    Minen, M. T., Anglin, C., Boubour, A., Squires, A., & Herrmann, L. (2018). Headache, 58(1), 22-44. 10.1111/head.13212
    Abstract
    Abstract
    Background: Migraine is one of the top 10 most disabling conditions among adults worldwide. Most migraine research is quantitative and indicates concerns about medication adherence, stigma, and more. Qualitative studies might reveal an improved understanding of migraine patients’ perspectives regarding migraine treatment. Objective: The aim of this study was to synthesize the qualitative research on migraine patients’ perspectives regarding migraine treatment to (a) identify common patterns across various types of migraine treatment studies and (b) inform future research. Methods: A systematic search for qualitative studies in the HA (HA) literature was conducted in Medline (PubMed), PsycINFO, EMBASE, CINAHL, Web of Science, Joanna Briggs Institute EBP Database, and The Cochrane Library. Search terms (subject headings and keywords) were HA, HA disorders, migraine, qualitative studies, and qualitative research. Qualitative studies were systematically identified by using published qualitative search filters recommended by The InterTASC Information Specialists’ Sub-Group (ISSG). The search was limited to English only, peer reviewed publications, and studies published between 1996 and 2016. For screening, additional inclusion criteria were (1) adult migraine patients; (2) must mention treatment in the title or study design of the abstract. Ten studies met the inclusion criteria. The Critical Appraisal Skills Program tool was applied to appraise study quality. Thematic analysis produced the codes and themes. Two authors read articles separately and individually created codes. Code lists were synthesized and themes emerged iteratively from the process. Results: Study sample sizes ranged from 10 to 33 participants, with our findings representing 161 participants. Data were collected either using interviews or focus groups. The more common methodologies were grounded theory and phenomenology. Few (3) studies described the number of headache (HA) days for inclusion in the study. Eight out of 10 used International Classification of Headache Disorders (ICHD) criteria. Our synthesis produced five major themes. The first theme was “Migraine patients’ difficulties with health care utilization,” and it included issues surrounding the cost of migraine treatment (seeing providers and prescription medications). The second theme was “Migraine patients’ perceived relationships with their providers,” which included the role and relationship with the provider, as well as trust in the provider and the providers’ knowledge in managing HAs. The third theme was “Thoughts about the various migraine treatments.” It was based on patients’ comments indicating an aversion to prescription medications, the use of non-pharmacological interventions for treatment, behavioral modification as a form of treatment, and the need for additional treatment options. The fourth and fifth themes were “Understanding diagnosis/triggers” and “Societal implications,” respectively. The latter theme included feelings of not being taken seriously and issues surrounding quality of life. Discussion: The metasynthesis revealed several key commonalities regarding patients’ perspectives on migraine treatment and identified new areas for research using a qualitative approach. Researchers conducting qualitative research with patients experiencing migraines might consider using and reporting more of the inclusion and exclusion criteria commonly used in migraine research, for example, reporting whether the ICHD criteria were used and the number of HA days for patients to be in a study. Future studies might be done to determine how the role of allied health care providers, for example, pharmacists, physical therapists, and psychologists, might be expanded to help with migraine treatment and ultimately to improve patient outcomes.

    Migration and cognitive function: a conceptual framework for Global Health Research

    Xu, H., Vorderstrasse, A. A., McConnell, E. S., Dupre, M. E., Østbye, T., & Wu, B. (2018). Global Health Research and Policy, 3(1). 10.1186/s41256-018-0088-5
    Abstract
    Abstract
    Background: Migration is a fundamental demographic process that has been observed globally. It is suggested that migration is an issue of global health importance that can have an immediate and lasting impact on an individual’s health and well-being. There is now an increasing body of evidence linking migration with cognitive function in older adults. In this paper, we synthesized the current evidence to develop a general conceptual framework to understand the factors contributing to the association between migration and cognitive function. Methods: A comprehensive review of the literature was conducted on the associations between migration and cognition among middle-aged and older adults. Results: Five potential mechanisms were identified from the literature: 1) socioeconomic status—including education, occupation, and income; 2) psychosocial factors—including social networks, social support, social stressors, and discrimination; 3) behavioral factors—including smoking, drinking, and health service utilization; 4) physical and psychological health status—including chronic conditions, physical function, and depression; and 5) environmental factors—including both physical and social environment. Several underlying factors were also identified—including early-life conditions, gender, and genetic factors. Conclusions: The factors linking migration and cognitive function are multidimensional and complex. This conceptual framework highlights potential implications for global health policies and planning on healthy aging and migrant health. Additional studies are needed to further examine these mechanisms to extend and refine our general conceptual framework.

    Minority stress and leukocyte gene expression in sexual minority men living with treated HIV infection

    Flentje, A., Kober, K. M., Carrico, A. W., Neilands, T. B., Flowers, E., Heck, N. C., & Aouizerat, B. E. (2018). Brain, Behavior, and Immunity, 70, 335-345. 10.1016/j.bbi.2018.03.016
    Abstract
    Abstract
    Sexual minority (i.e., non-heterosexual) individuals experience poorer mental and physical health, accounted for in part by the additional burden of sexual minority stress occurring from being situated in a culture favoring heteronormativity. Informed by previous research, the purpose of this study was to identify the relationship between sexual minority stress and leukocyte gene expression related to inflammation, cancer, immune function, and cardiovascular function. Sexual minority men living with HIV who were on anti-retroviral medication, had viral load < 200 copies/mL, and had biologically confirmed, recent methamphetamine use completed minority stress measures and submitted blood samples for RNA sequencing on leukocytes. Differential gene expression and pathway analyses were conducted comparing those with clinically elevated minority stress (n = 18) and those who did not meet the clinical cutoff (n = 20), covarying reactive urine toxicology results for very recent stimulant use. In total, 90 differentially expressed genes and 138 gene set pathways evidencing 2-directional perturbation were observed at false discovery rate (FDR) < 0.10. Of these, 41 of the differentially expressed genes and 35 of the 2-directionally perturbed pathways were identified as functionally related to hypothesized mechanisms of inflammation, cancer, immune function, and cardiovascular function. The neuroactive-ligand receptor pathway (implicated in cancer development) was identified using signaling pathway impact analysis. Our results suggest several potential biological pathways for future work investigating the relationship between sexual minority stress and health.

    Moving Beyond Age: An Exploratory Qualitative Study on the Context of Young African American Men and Women’s Sexual Debut

    Lanier, Y., Stewart, J. M., Schensul, J. J., & Guthrie, B. J. (2018). Journal of Racial and Ethnic Health Disparities, 5(2), 261-270. 10.1007/s40615-017-0366-9
    Abstract
    Abstract
    African American youth continue to be disproportionately affected by HIV. Early sexual debut has been identified as a major determinant of HIV risk. However, emerging research suggests that the overarching context in which first sex occurs may have greater implications for sexual health than simply age alone. The purpose of this exploratory, qualitative study was to better understand the broader context of African Americans’ sexual debut. In-depth, semi-structured interviews were conducted with 10 African American men and women aged 18–24 years. Thematic analysis was used to analyze the data. The mean age at sexual debut for the sample was 15.4 (SD = 3.3), and youth framed their sexual debut as positive (50%), negative (30%), and both positive and negative (20%). The majority of youth initiated pre-sex conversations with their partners to gauge potential interest in engaging in sexual activity, and all youth utilized at least one HIV/sexually transmitted infection and pregnancy prevention method. However, most youth failed to talk to their partners prior to sex about their past sexual histories and what the experience meant for their relationship. Key differences emerged between youth who framed the experience as positive and those who framed the experience as negative or both positive and negative in terms of their motivations for initiating sex (i.e., readiness to initiate sex, pressure, and emotionally safety) and post-sex emotions (i.e., remorse and contentment). Findings provide further support for examining the broader sexual context of African American’s sexual debut. A more comprehensive understanding of sexual debut will aid in the development and tailoring of sexual risk reduction programs targeting African American youth.

    Moving Beyond Pain as the Fifth Vital Sign and Patient Satisfaction Scores to Improve Pain Care in the 21st Century

    Scher, C., Meador, L., Van Cleave, J. H., & Reid, M. C. (2018). Pain Management Nursing, 19(2), 125-129. 10.1016/j.pmn.2017.10.010
    Abstract
    Abstract
    In an attempt to address the issue of undertreated pain, the Pain as the Fifth Vital Sign (P5VS) Initiative was established to improve the quality of pain care across clinical settings. This initiative included policy efforts such as mandatory pain screening and the implementation of pain-related questions on patient satisfaction surveys. These policies have failed to enhance the treatment of pain and may have unintentionally contributed, in part, to the opioid epidemic. To assess pain more effectively, an inter-professional team approach using multi-dimensional pain assessment tools is needed. The inter-professional team can use these multi-dimensional tools to conduct comprehensive assessments to measure aspects of the pain experience (e.g., psychological, spiritual and socio-emotional pain; impact on daily functioning) beyond its sensory component and establish realistic goals that align with patients' needs. To implement multi-dimensional pain assessments in busy clinical practices, nurses will need to play a central role. Nurses can work to ensure that patients complete the questionnaires prior to the visit. Nurses can also take the lead in the use of new technologies in the form of tablets, smart phones, and mobile apps to facilitate collecting patient-level data in the home or in a waiting room before their visits.

    Nursing Humanities: Teaching for a Sense of Salience

    Lim, F., & Marsaglia, M. J. (2018). Nursing Education Perspectives, 39(2), 121-122. 10.1097/01.NEP.0000000000000184
    Abstract
    Abstract
    Reports have indicated that nursing programs in the United States are not generally effective in teaching nursing science, natural science, the social sciences, and the humanities. The value of the lifelong study of humanities for nurses is the invitation for contemplation on the human experience so we can make informed moral, spiritual, and intellectual sense of the world. In essence, when we understand, we become more empathetic. This article adds to the call for teaching for a sense of salience in nursing through the meaningful synthesis of humanities in baccalaureate education.

    Nutrition Literacy among Cancer Survivors: Feasibility Results from the Healthy Eating and Living Against Breast Cancer (HEAL-BCa) Study: a Pilot Randomized Controlled Trial

    Parekh, N., Jiang, J., Buchan, M., Meyers, M., Gibbs, H., & Krebs, P. (2018). Journal of Cancer Education, 33(6), 1239-1249. 10.1007/s13187-017-1238-z
    Abstract
    Abstract
    Knowledge of nutrition among breast cancer patients is insufficient, despite their motivation to seek valid information about healthy food choices. This study examines the feasibility of nutrition education workshops for cancer survivors, to inform the design of a multi-center intervention. Fifty-nine female English-speaking breast cancer patients, who had completed treatment, were enrolled. Participants were randomized to the intervention or control group. The intervention group attended six nutrition education sessions, and the control group received brochures. Measurements were done at baseline and 3-month follow-up and included the Assessment Instrument for Breast Cancer (NLit-BCa), fruit/vegetable and general health literacy screeners. Height and weight were measured. Changes in nutrition literacy, health literacy, and food intake from baseline to follow-up (within-group change) were calculated for both groups (effect sizes were reported as Cohen’s d). Participants were mostly white, with a mean age of 58 years, BMI of 31.6 kg/m2, and had college degrees. Follow-up rates were high (89% = control and 77% = intervention group). At baseline, participants scored high for most NLit-BCa assessment components except food portions in both groups. At the 3-month follow-up, effect sizes (d) on the NLit-BCa ranged from −0.5 to 0.16. The study met its recruitment goals within 6 months. Focus groups indicated that (a) attending six sessions was acceptable, (b) patients found social/emotional support, (c) improvements should include information for special diets and booster sessions. This pilot study suggests that the intervention was acceptable and that scaling up of this intervention is feasible and could provide benefit to breast cancer survivors.

    Oncologists’ and Patients’ Perceptions of Initial, Intermediate, and Final Goals of Care Conversations

    Schulman-Green, D., Smith, C. B., Lin, J. J., Feder, S., & Bickell, N. A. (2018). Journal of Pain and Symptom Management, 55(3), 890-896. 10.1016/j.jpainsymman.2017.09.024
    Abstract
    Abstract
    Context: Although recommendations are for goals of care (GoC) conversations to happen early and often, their timing and content over the disease course remain unclear. Objectives: To describe perceptions of the timing and content of GoC conversations among oncologists and patients with advanced cancer. Methods: Semi-structured interviews with oncologists and patients at four hospitals in New York and Connecticut. We analyzed data using interpretive description. Results: Oncologists (n = 21) were 67% male, averaged 46 years old (range 34–68 years), and had a mean 20 years (range 8–42 years) in practice. Advanced cancer patients (n = 39) were 59% female with a mean age of 58 years (range 26–88 years). Oncologists and patients viewed GoC conversations along an initial, intermediate, and final continuum. Oncologists reported having initial GoC conversations to build rapport, provide disease information, and clarify and consider treatment intent and options. Intermediate conversations focused on changes in treatment and side effects. Final conversations occurred when patients were hospice-eligible and covered the shift to comfort care, a treatment summary, and advance directives. Timing and content were influenced by cancer type, disease status, and emotional state. Patients supported beginning GoC conversations early, but had different preferences for content of initial conversations. Some wanted complete information; others found this overwhelming. Patients felt intermediate GoC conversations should occur at decision points with time for processing. Content of intermediate and final conversations was dependent on patients’ prognosis, questions, and treatment decisions. Conclusion: Although GoC conversations should follow individual patient preferences, our findings offer structure for their timing and content.

    Organizational predictors and determinants of nurses' reported outcomes

    Abstract
    Abstract
    A 10-year research program systematically examined organizational features of nurses' workplaces in relation to nurse and patient outcomes. Its major results have been published in peer-reviewed international journals and presented here with replicated analyses and largely new datasets. First, a set of measures of nurse practice environment features and nurse work characteristics such as workload, decision latitude, and social capital along with burnout and work engagement as well as nurses' self-assessed job outcomes and quality of care was developed. These were examined in various populations of nurses such as those working in acute care hospitals and in long-term facilities. Secondly, models to explain associations between these selected variables were developed and tested in samples of acute hospital nurses. Thirdly, multilevel analyses of the associations between these variables confirmed that the phenomenon of organizational influences on work experiences occurred not only at the individual level but also at the team level in various study populations and across healthcare domains. Next, a longitudinal study design was set up to investigate the impact of planned transformations in the hospital organization as well as the implementation of the Productive Ward-Releasing Time to Care program aimed at strengthening practice environments and outcomes in a university hospital. Finally, a phenomenological study was undertaken to examine staff nurse and nurse manager perceptions and experiences of structural empowerment and the extent to which structural empowerment supports high-quality patient care. In addition, an explanatory sequential mixed methods design blended qualitative study results regarding staff nurses' experiences and perceptions of workload with prior quantitative results regarding structural empowerment to explain and interpret the findings of both models.

    Participation of Racial and Ethnic Minorities in Technology-Based Interventions to Self-Manage Type 2 Diabetes: A Scoping Review

    Jang, M., Johnson, C. M., D’Eramo-Melkus, G., & Vorderstrasse, A. A. (2018). Journal of Transcultural Nursing, 29(3), 292-307. 10.1177/1043659617723074
    Abstract
    Abstract
    Purpose: Strategies to decrease societal and cultural barriers for ethnic minorities to participate in health research are well established. However, limited data are available regarding participation of ethnic minorities in mobile and Internet technology–based interventions to self-manage type 2 diabetes where health disparities are predominant. Thus, the purpose was to understand the participation of ethnic minorities in technology-based intervention programs to manage type 2 diabetes. Design/Method: A scoping review was used to review a total of 21 intervention studies containing participant information about ethnic minorities and one qualitative study discussing participation of ethnic minorities. Findings: There was limited enrollment and participation of ethnic minorities. Technological barriers in addition to existing societal and cultural barriers were identified. Strategies to decrease the barriers were recommended. Conclusions: Technological barriers were identified on top of the societal and cultural barriers in traditional interventions. Further research to reduce the barriers is warranted.

    Patient Activation: A Key Component of Successful Advance Care Planning

    David, D., Barnes, D. E., McMahan, R. D., Shi, Y., Katen, M. T., & Sudore, R. L. (2018). Journal of Palliative Medicine, 21(12), 1778-1782. 10.1089/jpm.2018.0096
    Abstract
    Abstract
    Background: Patient activation - or knowledge, confidence, and skill managing overall health - is associated with improved health behaviors such as exercise; it is unknown whether it is associated with advance care planning (ACP). Objective: To determine whether patient activation is associated with ACP. Design: This is a cross-sectional study. Setting/Subjects: A total of 414 veterans (≥60 years) with serious and chronic illness enrolled in an ACP trial. Measures: Patient characteristics and self-report surveys included the validated 13-item patient activation measure (PAM, five-point Likert) (e.g., "Taking an active role in your own healthcare is the most important factor⋯") categorized into four levels (e.g., Level 1: "disengaged and overwhelmed" to Level 4: "maintaining behaviors"). ACP was measured with the ACP Engagement Survey including 57-item process scores (i.e., knowledge, contemplation, self-efficacy, readiness, 5-point Likert scale) and 25-item action scores (i.e., surrogate designation, yes/no items). Associations were determined with linear regression. Results: Participants were 71.1 ± 7.8 years of age, 43% were non-white, 9% were women, and 20% had limited health literacy. Higher PAM levels were associated with higher finances, having adult children, lower comorbidity, and more social support (p < 0.05). After adjusting for these characteristics, higher PAM (Level 4 vs. Level 1) was associated with higher ACP engagement (ACP process scores, 2.8 ± 0.7 vs. 3.8 ± 0.7 and action scores 9.7 ± 4.4 vs. 15.1 ± 6.0, p < 0.001). Conclusions: Higher patient activation to manage one's overall healthcare is associated with higher engagement in ACP. Interventions designed to foster general patient activation and self-efficacy to engage in health behaviors and disease management may also improve engagement in the ACP process.

    Patients' and oncologists' views on family involvement in goals of care conversations

    Lin, J. J., Smith, C. B., Feder, S., Bickell, N. A., & Schulman-Green, D. (2018). Psycho-Oncology, 27(3), 1035-1041. 10.1002/pon.4630
    Abstract
    Abstract
    Objective: Family members can significantly impact advanced cancer patients' treatment and are important participants in goals of care (GoC) conversations. Yet, research on patient and physician perspectives about family involvement and influence on GoC conversations is limited. Our purpose was to describe patients' and oncologists' perspectives about family involvement and influence on GoC conversations among patients with advanced cancer. Methods: We conducted semi-structured interviews at academic, community, and municipal hospitals (n = 4) with patients with advanced cancer (n = 39) and their oncologists (n = 21). Interviews were audiotaped and transcribed. We analyzed data using interpretive description. Three coders independently coded transcripts, compared codes, and resolved discrepancies. Results: We identified 4 themes common to patients and oncologists regarding family involvement in GoC conversations: (1) Presence and Duration of Family Involvement; (2) Family Expectations; (3) Protecting patients'/Family Members' Feelings; and (4) Patient-Family Disagreement. For patients, we identified 2 additional themes: (1) Family and Oncologist Relationship and (2) Effects of Cancer on Family. Both patients and oncologists emphasized the importance of family support for the patient's understanding of their illness and on patients' emotions. We also identified ways in which family involvement may benefit or prove challenging to GoC conversations. Conclusions: Patients and oncologists have similar views about family involvement in GoC conversations. Learning how to communicate with family members should be a critical component of physician education in palliative care.

    Perceived Empowerment, Social Support, and Quality of Life Among Chinese Older Residents in Long-Term Care Facilities

    Wang, J., Wang, J., Cao, Y., Jia, S., & Wu, B. (2018). Journal of Aging and Health, 30(10), 1595-1619. 10.1177/0898264318795724
    Abstract
    Abstract
    Objective: This study examines how older residents’ social support and perceived empowerment are associated with their quality of life (QOL) in long-term care (LTC) facilities in Shanghai, China, controlling for their health-related conditions, facility type, and other socio-demographic characteristics. Method: Using a convenient sampling approach, we selected nine LTC facilities in Shanghai, China. We surveyed 515 older residents from these facilities. Results: Older participants in this study rate their QOL, social support, and perceived empowerment as moderate, and these variables are positively associated with their QOL. Older residents who live in government-owned and private-run LTC facilities are more likely to have a higher level of perceived QOL compared with those living in government-run facilities. Discussion: There is an urgent need to increase staff awareness and capacity to empower older residents, and to engage them in their care plan and delivery. LTC facilities could provide more opportunities for older residents’ social networking within and outside LTC facilities. Improvement of older residents’ QOL is critical in the future development of resident-centered care models in LTC facilities.

    Perceived Stress, Its Physiological Correlates, and Quality of Life in Patients With Irritable Bowel Syndrome

    Weaver, K. R., Melkus, G. D., Fletcher, J., & Henderson, W. A. (2018). Biological Research for Nursing, 20(3), 312-320. 10.1177/1099800418756733
    Abstract
    Abstract
    Irritable bowel syndrome (IBS) is a chronic, common disorder of the gastrointestinal tract associated with high psychological comorbidity and diminished quality of life. Patients with IBS display a heightened sensitivity to stress, although the literature is inconsistent as to whether they have a dysregulated stress response. The purpose of the present investigation, a substudy of a larger research effort, was to examine physiological correlates of perceived stress in patients with IBS (cortisol and adrenocorticotropic hormone) and to explore associations between perceived stress and quality of life. A total of 101 participants (35 with IBS [predominant subtypes IBS-constipation and IBS-diarrhea] and 66 healthy controls [HCs]) completed self-report inventories regarding perceived stress and quality of life, and fasting peripheral blood was drawn. Participants with IBS did not differ from the HC in demographic or physiological measures but did differ in psychological measures, reporting significantly higher levels of perceived stress and lower levels of quality of life. Perceived stress and quality of life were not significantly associated in IBS participants. However, differential findings of the stress response were found within IBS participants by sex, race, and subtype. These findings illustrate the heterogeneity of the IBS patient population, underscore the necessity of evaluating larger sample sizes and increasing the diversity of such samples to include males and ethnic minorities, and demonstrate the importance of taking an individualized approach to evaluation and treatment in the IBS patient population.

    Place of Residence and Cognitive Function among the Adult Population in India

    Xu, H., Ostbye, T., Vorderstrasse, A. A., Dupre, M. E., & Wu, B. (2018). Neuroepidemiology, 50(3), 119-127. 10.1159/000486596
    Abstract
    Abstract
    Background: The place of residence has been linked to cognitive function among adults in developed countries. This study examined how urban and rural residence was associated with cognitive function among adults in India. Methods: The World Health Organization Study on Global AGEing and Adult Health data was used to examine cognition among 6,244 community-residing adults age 50+ in 6 states in India. Residential status was categorized as urban, rural, urban-to-urban, rural-to-urban, rural-to-rural, and urban-to-rural. Cognition was assessed by immediate and delayed recall tests, digit span test, and verbal fluency test. Multilevel models were used to account for state-level differences and adjusted for individual-level sociodemographic, psychosocial, and health-related factors. Results: Urban residents and urban-to-urban migrants had the highest levels of cognition, whereas rural residents and those who migrated to (or within) rural areas had the lowest cognition. The differences largely persisted after adjustment for multiple covariates; however, rural-to-urban migrants had no difference in cognition from urban residents once socioeconomic factors were taken into account. Conclusion: Cognition among adults in India differed significantly according to their current and past place of residence. Socioeconomic factors played an important role in the cognitive function of adults in urban areas.

    Pre-pregnancy or first-trimester risk scoring to identify women at high risk of preterm birth

    Baer, R. J., McLemore, M. R., Adler, N., Oltman, S. P., Chambers, B. D., Kuppermann, M., Pantell, M. S., Rogers, E. E., Ryckman, K. K., Sirota, M., Rand, L., & Jelliffe-Pawlowski, L. L. (2018). European Journal of Obstetrics and Gynecology and Reproductive Biology, 231, 235-240. 10.1016/j.ejogrb.2018.11.004
    Abstract
    Abstract
    Objective To develop a pre-pregnancy or first-trimester risk score to identify women at high risk of preterm birth. Study design In this retrospective cohort analysis, the sample was drawn from California singleton livebirths from 2007 to 2012 with linked birth certificate and hospital discharge records. The dataset was divided into a training (2/3 of sample) and a testing (1/3 of sample) set for discovery and validation. Predictive models for preterm birth using pre-pregnancy or first-trimester maternal factors were developed using backward stepwise logistic regression on a training dataset. A risk score for preterm birth was created for each pregnancy using beta-coefficients for each maternal factor remaining in the final multivariable model. Risk score utility was replicated in a testing dataset and by race/ethnicity and payer for prenatal care. Results The sample included 2,339,696 pregnancies divided into training and testing datasets. Twenty-three maternal risk factors were identified including several that were associated with a two or more increased odds of preterm birth (preexisting diabetes, preexisting hypertension, sickle cell anemia, and previous preterm birth). Approximately 40% of women with a risk score ≥ 3.0 in the training and testing samples delivered preterm (40.6% and 40.8%, respectively) compared to 3.1–3.3% of women with a risk score of 0.0 [odds ratio (OR) 13.0, 95% confidence interval (CI) 10.7–15.8, training; OR 12.2, 95% CI 9.4–15.9, testing). Additionally, over 18% of women with a risk score ≥ 3.0 had an adverse outcome other than preterm birth. Conclusion Maternal factors that are identifiable prior to pregnancy or during the first-trimester can be used create a cumulative risk score to identify women at the lowest and highest risk for preterm birth regardless of race/ethnicity or socioeconomic status. Further, we found that this cumulative risk score could also identify women at risk for other adverse outcomes who did not have a preterm birth. The risk score is not an effective screening test, but does identify women at very high risk of a preterm birth.

    Prediction of preterm birth with and without preeclampsia using mid-pregnancy immune and growth-related molecular factors and maternal characteristics

    Jelliffe-Pawlowski, L. L., Rand, L., Bedell, B., Baer, R. J., Oltman, S. P., Norton, M. E., Shaw, G. M., Stevenson, D. K., Murray, J. C., & Ryckman, K. K. (2018). Journal of Perinatology, 38(8), 963-972. 10.1038/s41372-018-0112-0
    Abstract
    Abstract
    Objective:: To evaluate if mid-pregnancy immune and growth-related molecular factors predict preterm birth (PTB) with and without (±) preeclampsia. Study design:: Included were 400 women with singleton deliveries in California in 2009–2010 (200 PTB and 200 term) divided into training and testing samples at a 2:1 ratio. Sixty-three markers were tested in 15–20 serum samples using multiplex technology. Linear discriminate analysis was used to create a discriminate function. Model performance was assessed using area under the receiver operating characteristic curve (AUC). Results:: Twenty-five serum biomarkers along with maternal age <34 years and poverty status identified >80% of women with PTB ± preeclampsia with best performance in women with preterm preeclampsia (AUC = 0.889, 95% confidence interval (0.822–0.959) training; 0.883 (0.804–0.963) testing). Conclusion:: Together with maternal age and poverty status, mid-pregnancy immune and growth factors reliably identified most women who went on to have a PTB ± preeclampsia.
