ABSTRACT
Understanding the progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) is needed to identify patients who would benefit from closer clinical surveillance. Given that two of the defining criteria of MM are renal failure and anemia, we described the trajectories of creatinine (Cr) and hemoglobin (Hgb) over time in patients with a diagnosis of MGUS. Patients diagnosed with MGUS (n = 424) were identified by a previously validated case-finding algorithm using health claims and electronic health record data (2007-2015) and followed through 2018. Group-based trajectory modeling identified patients with distinct laboratory value trajectories of Cr (mg/dl) and Hgb (g/dl). Most patients were non-Hispanic White (97.6%) with a mean age of 75 years at MGUS diagnosis. Three multi-trajectory groups were identified: (1) Normal Cr/Hgb (n = 225; 53.1%)-stable serum Cr levels and decreasing, normal Hgb levels; (2) Normal Cr/lower-normal Hgb group (n = 188; 44.3%)-stable, slightly elevated levels of Cr and decreasing levels of Hgb; and (3) High Cr/borderline Hgb group (n = 11; 2.6%)-increased Cr levels and stable low levels of Hgb. Patients with MGUS in Group 2 were older than patients in other groups, and patients in group 3 had more comorbidities than participants in all other groups. Few patients developed MM during the study period. We were able to identify distinct biomarker trajectories in patients with MGUS over time. Future research should investigate how these trajectories may be related to the risk of progression to MM, including M-protein levels.

INTRODUCTION: This study evaluated the impact of receiving a monoclonal gammopathy of undetermined significance (MGUS) diagnosis on healthcare utilization from patients at a community-based multispecialty provider organization. METHODS: A cohort of patients with MGUS (n = 429) were matched on sex, age, and length of enrollment to a cohort of patients without MGUS (n = 1286). Healthcare utilization was assessed: 1-12 months before, 1 month before and after, and 1-12 months after diagnosis/index date. Multivariable conditional Poisson models compared change in utilization of each service in patients with and without MGUS. RESULTS: During the 2 months around diagnosis/index date, the rates of emergency room, hospital and outpatient visits were higher for patients with MGUS than patients without MGUS. In the year before MGUS diagnosis, the association was still elevated, although attenuated. CONCLUSION: Understanding the care of MGUS patients is important given that multiple myeloma patients with a pre-existing MGUS diagnosis may have a better prognosis.

BACKGROUND: Motivational messaging is a frequently used digital intervention to promote positive health behavior changes, including smoking cessation. Typically, motivational messaging systems have not actively sought feedback on each message, preventing a closer examination of the user-system engagement. This study assessed the granular user-system engagement around a recommender system (a new system that actively sought user feedback on each message to improve message selection) for promoting smoking cessation and the impact of engagement on cessation outcome. METHODS: We prospectively followed a cohort of current smokers enrolled to use the recommender system for 6 months. The system sent participants motivational messages to support smoking cessation every 3 days and used machine learning to incorporate user feedback (i.e., user's rating on the perceived influence of each message, collected on a 5-point Likert scale with 1 indicating strong disagreement and 5 indicating strong agreement on perceiving the influence on quitting smoking) to improve the selection of the following message. We assessed user-system engagement by various metrics, including user response rate (i.e., the percent of times a user rated the messages) and the perceived influence of messages. We compared retention rates across different levels of user-system engagement and assessed the association between engagement and the 7-day point prevalence abstinence (missing outcome = smoking) by using multiple logistic regression. RESULTS: We analyzed data from 731 participants (13% Black; 73% women). The user response rate was 0.24 (SD = 0.34) and user-perceived influence was 3.76 (SD = 0.84). The retention rate positively increased with the user response rate (trend test P < 0.001). Compared with non-response, six-month cessation increased with the levels of response rates: low response rate (odds ratio [OR] = 1.86, 95% confidence interval [CI]: 1.07-3.23), moderate response rate (OR = 2.30, 95% CI: 1.36-3.88), high response rate (OR = 2.69, 95% CI: 1.58-4.58). The association between perceived message influence and the outcome showed a similar pattern. CONCLUSIONS: High user-system engagement was positively associated with both high retention rate and smoking cessation, suggesting that investigation of methods to increase engagement may be crucial to increase the impact of the recommender system for smoking cessation.

This research tests the independent contribution of social capital and the use of the internet to obtain health information to support maternal-child communication about peer pressure to have sex among Puerto Rican families. A sample of 413 Puerto Rican households in Springfield, MA provides the data to independently test these hypotheses. The results of a logistic regression model suggest that Puerto Rican mothers with increased social capital and who accessed the internet for health information are more likely to communicate with their adolescent children about peer pressure to have sex. The combination of these two mechanisms provide opportunities to convey culturally generated resources to Puerto Rican mothers to assist them in helping their children develop healthy sexual behaviors.

BACKGROUND: Many research participants are misinformed about research terms, procedures, and goals; however, no validated instruments exist to assess individual's comprehension of health-related research information. We propose research literacy as a concept that incorporates understanding about the purpose and nature of research. OBJECTIVES: We developed the Research and Knowledge Scale (RaKS) to measure research literacy in a culturally, literacy-sensitive manner. We describe its development and psychometric properties. RESEARCH DESIGN: Qualitative methods were used to assess perspectives of research participants and researchers. Literature and informed consent reviews were conducted to develop initial items. These data were used to develop initial domains and items of the RaKS, and expert panel reviews and cognitive pretesting were done to refine the scale. We conducted psychometric analyses to evaluate the scale. SUBJECTS: The cross-sectional survey was administered to a purposive community-based sample (n=430) using a Web-based data collection system and paper. MEASURES: We did classic theory testing on individual items and assessed test-retest reliability and Kuder-Richardson-20 for internal consistency. We conducted exploratory factor analysis and analysis of variance to assess differences in mean research literacy scores in sociodemographic subgroups. RESULTS: The RaKS is comprised of 16 items, with a Kuder-Richardson-20 estimate of 0.81 and test-retest reliability 0.84. There were differences in mean scale scores by race/ethnicity, age, education, income, and health literacy (all P<0.01). CONCLUSIONS: This study provides preliminary evidence for the reliability and validity of the RaKS. This scale can be used to measure research participants' understanding about health-related research processes and identify areas to improve informed decision-making about research participation.

BACKGROUND: Overweight and obesity are prevalent among young women and are greater among minority and low-income women. The postpartum period is critical in women's weight trajectories as many women do not lose their pregnancy weight, and others lose some and then plateau or experience weight gain. Excess weight puts women at greater risk of chronic disease and thus weight loss in the postpartum period may be key to the long-term health of young women. This paper describes the design and methods of a randomized clinical trial of Fresh Start, an innovative narrative-based group intervention aimed at promoting postpartum weight loss among low-income, diverse women. METHODS/DESIGN: Study participants were recruited from the five sites of the Women, Infants and Children (WIC) program in central Massachusetts. Participants were English-speaking, age ≥ 18 years, 6 weeks to 6 months postpartum, with a body mass index (BMI) ≥ 27 kg/m(2). The Fresh Start postpartum weight loss intervention, adapted from the Diabetes Prevention Program (DPP) in collaboration with WIC staff and clients, consisted of an 8-week group-based curriculum followed by nine monthly telephone calls. It included a narrative component (i.e., storytelling), group discussions, print materials and access to exercise facilities. The study is a two-arm randomized controlled trial. The control condition included print materials and access to exercise facilities. In-person assessments were conducted at baseline and at 6 and 12 months following the eight-week intervention phase. DISCUSSION: The Fresh Start intervention translated key elements of an evidence-based weight loss protocol into a format that is hypothesized to be relevant, acceptable and effective for the target audience of low-SES postpartum women. This novel intervention was developed in collaboration with WIC to be sustainable within the context of its clinics, which reach approximately 9 million individuals per year across the U.S. via 10,000 clinics.

Objective Only 9 % of women with young children consume a high quality diet. The association between sleep duration and health may be U-shaped. We examined diet quality in relation to sleep duration among US women within 5 years of childbirth. Methods Data were from non-pregnant women aged 20-44 years within 5 years of childbirth who completed two 24-h dietary recalls (N = 896) in the National Health and Nutrition Examination Survey 2005-2012. Self-reported weekday/workday sleep duration was categorized as short (≤6 h), adequate (7-8 h), or long (≥9 h). The Healthy Eating Index (HEI-2010, range 0-100) estimated overall and components of diet quality. Multivariable-adjusted linear regression models estimated the association between sleep duration and diet quality, adjusting for age, race/ethnicity, and education. Results Thirty-four percent of women reported short, 57.1 % adequate, and 8.6 % long sleep duration. The average diet quality total score was 47.4 out of 100. Short sleep duration was not associated with diet quality. Long sleep duration was associated with lower quality diet (ß = -4.3; 95 % CI -8.1 to -0.4), lower consumption of total fruit (ß = -0.7; 95 % CI -1.3 to -0.1), whole fruit (ß = -0.9; 95 % CI -1.6 to -0.2), and total protein (ß = -0.7; 95 % CI -1.3 to -0.03), and higher consumption of empty calories (ß = 2.2; 95 % CI -4.3 to -0.1). Conclusions for practice Future studies should examine the longitudinal association between sleep duration and diet quality among women following childbirth and whether interventions to improve sleep can enhance diet quality.

INTRODUCTION: The present study characterizes the tobacco use, quitting behaviors, and health characteristics of cigarette smokers who did not change their smoking pattern over the past 6 months and have used electronic cigarettes (ECs) in the past 30 days. This is an important subpopulation to characterize if EC dual use with cigarettes continues to grow. METHODS: Participants (N = 2,376) from a research survey panel completed an online cross-sectional survey between June and August 2012. Sampling was stratified to recruit equal numbers of cigarette smoking participants by race/ethnicity (Black, Hispanic, and Caucasian) and smoking frequency (nondaily and daily). All displayed a stable rate of smoking for the past 6 months and were not currently in treatment. Bivariate and multivariate analyses were used to examine correlates of current EC use (any use within the past 30 days). RESULTS: Current EC use was reported by 9.2% (n = 219) of the total sample. Of current EC users, 44% reported having used ECs as a quit method. Bivariate and multivariate analyses showed that current EC use was significantly associated with greater nicotine dependence, concurrent poly-tobacco use, more past-year quit attempts, past use of multiple cessation methods, and more depressive symptoms. No demographic variables were significantly associated with current EC use. CONCLUSIONS: This study suggests that stable smokers who currently use ECs possess characteristics that are associated with difficulty in achieving smoking cessation. These characteristics should be considered when examining the effectiveness of ECs on cessation and in designing future cessation trials using ECs.

INTRODUCTION: Women with a history of gestational diabetes mellitus (GDM) have elevated risk of developing type 2 diabetes. Diet quality plays an important role in the prevention of type 2 diabetes. We compared diet quality among childbearing women with a history of GDM with the diet quality of childbearing women without a history of GDM. METHODS: We used data from the National Health and Nutrition Examination Survey for 2007 through 2010. We included women without diabetes aged 20 to 44 years whose most recent live infant was born within the previous 10 years and who completed two 24-hour dietary recalls. The Healthy Eating Index (HEI)-2010 estimated overall and component diet quality. Multivariable linear regression models estimated the association between a history of GDM and current diet quality, adjusting for age, education, smoking status, and health risk for diabetes. RESULTS: A history of GDM was reported by 7.7% of women. Compared with women without a history of GDM, women with a history of GDM had, on average, 3.4 points lower overall diet quality (95% confidence interval [CI], -6.6 to -0.2) and 0.9 points lower score for consumption of green vegetables and beans (95% CI, -1.4 to -0.4). Other dietary component scores did not differ by history of GDM. CONCLUSION: In the United States, women with a history of GDM have lower diet quality compared with women who bore a child and do not have a history of GDM. Improving diet quality may be a strategy for preventing type 2 diabetes among childbearing women.

BACKGROUND: The Community Health Advisor (CHA) model has been widely used to recruit rural and low-income, mostly African American women into clinical and behavioral research studies. However, little is known about its effectiveness in promoting retention and adherence of such women in clinical trials. METHODS: The Community-Based Retention Intervention Study evaluated the effectiveness of a community-based intervention strategy using the CHA model and the empowerment theory to improve the retention and adherence of minority and low-income women in clinical trials. The research strategy included the training and use of the volunteer CHAs as research partners. The target population included women participating in the University of Alabama at Birmingham clinical site of the Atypical Squamous Cells of Undetermined Significance-Low-Grade Squamous Intraepithelial Lesion (ASCUS-LSIL) Triage Study (ALTS), a multicenter, randomized clinical trial. Two communities in Jefferson County, Alabama, that were matched according to population demographics were identified and randomly assigned to either an intervention group or a control group. Thirty community volunteers were recruited to be CHAs and to implement the intervention with the ALTS trial participants. In total, 632 ALTS participants agreed to participate in the project, including 359 in the intervention group, which received CHA care, and 273 in the control group, which received standard care. RESULTS: Adherence rates for scheduled clinic visits were significantly higher in the intervention group (80%) compared with the control group (65%; P < .0001). CONCLUSIONS: The results indicate that volunteer CHAs can be trained to serve as research partners and can be effective in improving the retention and adherence of minority and low-income women in clinical trials.

OBJECTIVES: Much of the excessive morbidity and mortality from cardiovascular disease among African Americans results from low adherence to anti-hypertensive medications. Therefore, we examined the association between weight-based discrimination and medication adherence. METHODS: We used cross-sectional data from low-income African Americans with hypertension. Ordinal logistic regression estimated the odds of medication non-adherence in relation to weight-based discrimination adjusted for age, sex, education, income, and weight. RESULTS: Of all participants (n = 780), the mean (SD) age was 53.7 (9.9) years and the mean (SD) weight was 210.1 (52.8) lbs. Reports of weight-based discrimination were frequent (28.2%). Weight-based discrimination (but not weight itself) was associated with medication non-adherence (OR: 1.94; 95% CI: 1.41-2.67). A substantial portion 38.9% (95% CI: 19.0%-79.0%) of the association between weight-based discrimination and medication non-adherence was mediated by medication self-efficacy. CONCLUSION: Self-efficacy is a potential explanatory factor for the association between reported weight-based discrimination and medication non-adherence. Future research should develop and test interventions to prevent weight-based discrimination at the societal, provider, and institutional levels.

OBJECTIVES: Depression is common during pregnancy and the year following childbirth (the perinatal period). This study assessed the association of depressive symptoms and contraception decisions in perinatal individuals. STUDY DESIGN: We conducted a secondary analysis using data from the PRogram in Support of Moms (PRISM) study, a cluster randomized controlled trial of active interventions which aimed to address perinatal depression. This analysis included 191 individuals aged 18-45 who screened positive for depression on the Edinburgh Postnatal Depression Scale (EPDS, score ≥10) during pregnancy or up to 3 months postpartum. We assessed contraception intent and method choice at 1-3 months postpartum. At 5-7 months postpartum, we assessed contraceptive method used and EPDS depression scores. We used logistic regressions to examine the relationship between depression and contraceptive use/method. RESULTS: At 1-3 months postpartum, the majority of participants (76.4%) expressed an intention to use contraception. Of those, over half (53.4%) indicated a preference for higher effectiveness contraception methods. Participants with persistent depression symptoms (positive EPDS) at 5-7 months were significantly less likely to report using higher effectiveness contraceptive methods (aOR = 0.28, 95% CI = 0.11-0.70) compared to those without. Among participants with persistent depressive symptoms, 21.1% reported using a contraception method of lower effectiveness than had originally intended. CONCLUSION: Perinatal individuals with persistent depressive symptoms at 5-7 months postpartum reported greater use of less-effective contraception methods than originally planned. IMPLICATIONS: We found associations between perinatal depression and use of less effective contraception use. Provider discussions regarding contraception planning is important, particularly in those with perinatal depression symptoms.

BACKGROUND: Diagnostic yield of video capsule endoscopy (VCE) may be higher if it is performed closer to the time of overt obscure GI bleeding (OOGIB). OBJECTIVE: To evaluate the diagnostic yield of VCE and rate of therapeutic intervention for OOGIB for inpatients and outpatients with respect to timing of the intervention. DESIGN: Retrospective cohort study. SETTING: Tertiary academic center. PATIENTS: Patients who had VCE for OOGIB between August 2008 and August 2010. INTERVENTIONS: VCE for inpatients versus outpatients. MAIN OUTCOME MEASURES: Diagnostic yield and rate of therapeutic intervention for inpatients versus outpatients. RESULTS: One hundred forty-four inpatients (65 women) and 116 outpatients (49 women) were included. Diagnostic yield was 65.9% for inpatients versus 53.4% for outpatients (P = .054). Inpatients were divided into those who had VCE within 3 days (<3 days; n = 90) of admission versus after 3 days (>3 days; n = 54). Active bleeding and/or an angioectasia was found in 44.4% of the <3-day group compared with 27.8% of the >3-day group (P = .046) versus 25.8% of the outpatients. Therapeutic intervention was performed in 18.9% of the <3-day group versus 7.4% of the >3-day group (P = .046) versus 10.3% of outpatients. Diagnostic yield and therapeutic intervention rate between the >3-day group and outpatients were not significantly different. Length of stay (days) was less in the <3-day cohort, at 6.1 versus 10.3 in the >3-day cohort (P < .0001). LIMITATIONS: Long-term outcomes were not studied. This was a retrospective study. CONCLUSIONS: Early deployment of VCE within 3 days of admission results in a higher diagnostic yield and therapeutic intervention rate and an associated reduction of length of stay.

Background Hypertension is an important modifiable risk factor of serious maternal morbidity and mortality. Social determinants of health (SDoH) influence hypertension outcomes and may contribute to racial and ethnic differences in hypertension control. Our objective was to assess SDoH and blood pressure (BP) control by race and ethnicity in US women of childbearing age with hypertension. Methods and Results We studied women (aged 20-50 years) with hypertension (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg or use of antihypertensive medication) in the National Health and Nutrition Examination Surveys 2001 to 2018. SDoH and BP control (systolic BP <140 mm Hg and diastolic BP <90 mm Hg) were examined by race and ethnicity (White race, Black race, Hispanic ethnicity, and Asian race). Using multivariable logistic regression, odds of uncontrolled BP by race and ethnicity were modeled, adjusting for SDoH, health factors, and modifiable health behaviors. Responses on hunger and affording food determined food insecurity status. Across women of childbearing age with hypertension (N=1293), 59.2% were White race, 23.4% were Black race, 15.8% were Hispanic ethnicity, and 1.7% were Asian race. More Hispanic and Black women experienced food insecurity than White women (32% and 25% versus 13%; both P<0.001). After SDoH, health factor, and modifiable health behavior adjustment, Black women maintained higher odds of uncontrolled BP than White women (odds ratio, 2.31 [95% CI, 1.08-4.92]), whereas Asian and Hispanic women showed no difference. Conclusions We identified racial inequities in uncontrolled BP and food insecurity among women of childbearing age with hypertension. Further exploration beyond the SDoH measured is needed to understand the inequity in hypertension control in Black women.

Importance: Novel data science and marketing methods of smoking-cessation intervention have not been adequately evaluated. Objective: To compare machine learning recommender (ML recommender) computer tailoring of motivational text messages vs a standard motivational text-based intervention (standard messaging) and a viral peer-recruitment tool kit (viral tool kit) for recruiting friends and family vs no tool kit in a smoking-cessation intervention. Design, Setting, and Participants: This 2 ×2 factorial randomized clinical trial with partial allocation, conducted between July 2017 and September 2019 within an online tobacco intervention, recruited current smokers aged 18 years and older who spoke English from the US via the internet and peer referral. Data were analyzed from March through May 2022. Interventions: Participants registering for the online intervention were randomly assigned to the ML recommender or standard messaging groups followed by partially random allocation to access to viral tool kit or no viral tool kit groups. The ML recommender provided ongoing refinement of message selection based on user feedback and comparison with a growing database of other users, while the standard system selected messages based on participant baseline readiness to quit. Main Outcomes and Measures: Our primary outcome was self-reported 7-day point prevalence smoking cessation at 6 months. Results: Of 1487 participants who smoked (444 aged 19-34 years [29.9%], 508 aged 35-54 years [34.1%], 535 aged ≥55 years [36.0%]; 1101 [74.0%] females; 189 Black [12.7%] and 1101 White [78.5%]; 106 Hispanic [7.1%]), 741 individuals were randomly assigned to the ML recommender group and 746 individuals to the standard messaging group; viral tool kit access was provided to 745 participants, and 742 participants received no such access. There was no significant difference in 6-month smoking cessation between ML recommender (146 of 412 participants [35.4%] with outcome data) and standard messaging (156 of 389 participants [40.1%] with outcome data) groups (adjusted odds ratio, 0.81; 95% CI, 0.61-1.08). Smoking cessation was significantly higher in viral tool kit (177 of 395 participants [44.8%] with outcome data) vs no viral tool kit (125 of 406 participants [30.8%] with outcome data) groups (adjusted odds ratio, 1.48; 95% CI, 1.11-1.98). Conclusions and Relevance: In this study, machine learning-based selection did not improve performance compared with standard message selection, while viral marketing did improve cessation outcomes. These results suggest that in addition to increasing dissemination, viral recruitment may have important implications for improving effectiveness of smoking-cessation interventions.

BACKGROUND: Storytelling is emerging as a powerful tool for health promotion in vulnerable populations. However, these interventions remain largely untested in rigorous studies. OBJECTIVE: To test an interactive storytelling intervention involving DVDs. DESIGN: Randomized, controlled trial in which comparison patients received an attention control DVD. Separate random assignments were performed for patients with controlled or uncontrolled hypertension. (ClinicalTrials.gov registration number: NCT00875225) SETTING: An inner-city safety-net clinic in the southern United States. PATIENTS: 230 African Americans with hypertension. INTERVENTION: 3 DVDs that contained patient stories. Storytellers were drawn from the patient population. MEASUREMENTS: The outcomes were differential change in blood pressure for patients in the intervention versus the comparison group at baseline, 3 months, and 6 to 9 months. RESULTS: 299 African American patients were randomly assigned between December 2007 and May 2008 and 76.9% were retained throughout the study. Most patients (71.4%) were women, and the mean age was 53.7 years. Baseline mean systolic and diastolic pressures were similar in both groups. Among patients with baseline uncontrolled hypertension, reduction favored the intervention group at 3 months for both systolic (11.21 mm Hg [95% CI, 2.51 to 19.9 mm Hg]; P = 0.012) and diastolic (6.43 mm Hg [CI, 1.49 to 11.45 mm Hg]; P = 0.012) blood pressures. Patients with baseline controlled hypertension did not significantly differ over time between study groups. Blood pressure subsequently increased for both groups, but between-group differences remained relatively constant. LIMITATION: This was a single-site study with 23% loss to follow-up and only 6 months of follow-up. CONCLUSION: The storytelling intervention produced substantial and significant improvements in blood pressure for patients with baseline uncontrolled hypertension.

Background: There is scarcity of smoking cessation programs that take gender into account during its development, implementation, and evaluation. We evaluated the efficacy of a theory-based, culturally, and gender-relevant smoking cessation intervention delivered by Community Health Workers (CHWs) among Brazilian women that augments the smoking cessation program offered through the public health system (PHS). Materials and Methods: A total of 328 women current smokers (100% cigarette smokers) were recruited across 8 towns in a tobacco producing state in Brazil between 2014 and 2017. Four towns were randomly assigned to the intervention (12 home visits by a CHW and a scheduled appointment to attend the smoking cessation program at the PHS) and four towns to the control condition (scheduled appointment to attend the cessation program at the PHS). The primary outcome was self-reported 7-day smoked tobacco abstinence at 7-month follow-up with biochemical verification. Results: Retention at 7-month follow-up was 80.7% (intervention) and 85.1% (control). Using intention-to-treat analysis, abstinence at 7-month-follow-up was 20% in the intervention arm versus 11% in the control arm. Multivariable modeling showed that participants in the intervention arm had 1.88 times the odds of self-reported smoking cessation than control participants after adjustment for depressive symptomatology, self-efficacy, and having someone in the house who smokes. Besides the intervention, only self-efficacy remained significant in the full model as a predictor of cessation. Replication of these analyses using the objective measure of carbon monoxide at a cutoff score of 8 ppm yielded similar results. Conclusions: A theory-based, culturally, and gender-relevant intervention, delivered by CHWs, can successfully promote smoking cessation among women. Clinical Trial Registration No. NCT03845413.

BACKGROUND AND AIM: Patients with lung cancer experience high rates of psychosocial distress. They are also more likely to have unresolved, unmet social needs which may contribute to psychosocial distress. Despite this, neighborhood-level social determinants of health (SDOH) in relation to psychosocial distress have not been adequately investigated in patients with lung cancer. The goal of this study is to examine the association between neighborhood-level SDOH and psychosocial distress among a sample of newly diagnosed patients with lung cancer. METHODS: This cross-sectional study included newly diagnosed, adult lung cancer patients from an accredited cancer center. Psychosocial distress was measured with the Distress Thermometer. Neighborhood-level SDOH indicators for income and education were used to create a composite SDOH variable categorized into low, medium, and high deprivation levels. Covariates were age, gender, race/ethnicity, comorbidity index, cancer stage, and insurance status. Using multivariate logistic regression modeling, the association of psychosocial distress with the neighborhood-level SDOH was examined. RESULTS: The prevalence of psychosocial distress in the sample was 58.4%. Neighborhood-level SDOH indicators were not significantly associated with psychosocial distress. Higher odds of psychosocial distress were significantly associated with being female and having distant or regional cancer versus localized cancer. The age group 66-75 years was significantly associated with lower distress compared with those aged <65 years. CONCLUSIONS: Psychosocial distress was consistently high across all the SDOH deprivation categories; but these neighborhood-level SDOH indicators do not appear to be predictive of psychosocial distress at the time of diagnosis of lung cancer.

BACKGROUND: Hypertension (HTN) in pregnancy is a leading cause of maternal mortality in the United States. Contraception is widely used, and estrogen-based combined hormonal forms are known to increase blood pressure (BP). With nearly half of pregnancies unplanned and many antihypertensive medications teratogenic, appropriate contraception is critical in child-bearing age women with HTN. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) from 2001 to 2018, we evaluated contraception and antihypertensive medication use in women of child-bearing age (20-50âyears). Women who had undergone sterilization or menopause were excluded. HTN was defined based on a self-reported provider diagnosis and BP ≥130/80âmm Hg or antihypertensive medication use. Contraception included non-barrier methods (pills/patch/ring, injections, long-acting reversible contraceptives) or consistent condom use. Multivariable logistic regression was used to model the odds of contraception use. Temporal trends in contraception use were reported. RESULTS: Of the 8726 women, 12.4% had HTN with mean age (standard error) 36.0 (0.3) years. In women with HTN, 9.2% used non-barrier contraception and 10.4% used condoms only. Over half (52.7%) of women with HTN on antihypertensive medications were taking medications contraindicated in pregnancy, with no difference seen by contraceptive status. In logistic regression models, contraceptive use was lower in the older-aged women. In women with HTN on non-barrier contraception, combined hormonal contraceptive use declined, from 100% (2001-2006) to 81.4% (2013-2018, Pâ<â0.001). CONCLUSIONS: Many women with self-reported HTN are not using adequate contraception. Of the small proportion on non-barrier contraceptives, the majority are using estrogen-based, BP-raising methods.

OBJECTIVE: To examine trends in the direct acting antiviral (DAA) uptake in a multi-state Medicaid population with hepatitis C virus (HCV) prior to and after ledipasvir/sofosbuvir (LDV/SOF) approval and changes in prior authorization (PA) requirements. DATA SOURCES: Analyses utilized enrollment, medical, and pharmacy claims in four states, December 2013-December 2017. STUDY DESIGN: An interrupted time series examined trends in uptake (1+ claim for a DAA) before and after two events: LDV/SOV approval (October 2014) and lifting of PA requirements for 40% of members (July 2016). Analyses were also performed in subgroups defined by the number and dates of change in PA requirements in members' Medicaid plans. DATA COLLECTION/EXTRACTION METHODS: Members aged 18-64 years with an ICD code for HCV were included in the sample from diagnosis date until treatment initiation or Medicaid disenrollment. PRINCIPAL FINDINGS: The annual sample size ranged from 38,302 to 45,005 with approximately 30% ages 18-34 years and 40% female. In December 2013, 0.08% was treated, rising to 0.74% in December 2017 (p < 0.001). Uptake increased from 0.34%/month in October 2014 to 0.70%/month after LDV/SOF approval, (p < 0.001), and increased relative to the pre-LDV/SOV trend through June 2016 (p = 0.04). Uptake increased to 1.18%/month after PA change, (p < 0.001) and remained flat through 2017 (p = 0.64). Cumulatively, 20.1% were treated by December 2017. In plans with few/no requirements through 2017, uptake increased to 1.19%/month after LDV/SOF approval (p < 0.001) and remained flat through 2017 (p = 0.11), with 22.2% cumulatively treated. Among plans that lifted PA requirements from three to zero in mid-2016, uptake did not increase after LDV/SOF approval (p = 0.36) but did increase to 1.41%/month (p < 0.001) after PA change, with 18.1% cumulatively treated. CONCLUSIONS: HCV Treatment increased through 2017. LDV/SOF approval and lifting PA requirements led to an increase in uptake followed by flat monthly utilization. Cumulative uptake was higher in plans with few/no PA requirements relative to those with three requirements through mid-2016.
