RESUMEN
PURPOSE: This study aimed to explore the association between preterm birth and telomere length of maternal peripheral blood in African American women. METHODS: 78 African American women were recruited for this study between 2018 and 2023 from 2 prenatal clinics in central and east Texas. Participants provided blood samples and completed clinic questionnaires, with clinical data collected from their post-delivery medical records. Telomere length was measured using monochrome multiplex quantitative real-time polymerase chain reaction. Linear regression and multinomial logistic regression were used to analyze the association between telomere length and gestational length. Kruskal-Wallis's test and Fisher's exact test were used to compare preterm birth, early-term birth and full-term birth by telomere length, social-demographic characteristics, stress and discrimination. RESULTS: The rates of preterm birth was higher in pregnant women with shorter telomeres. After adjusting for confounders, for every 10-units increase in the relative telomere-to-single-copy gene (T/S) ratio, gestational days increased by 1.090 days (90% CI 0.182, 1.997), and for every 10-units decrease in the T/S ratio, the odds of preterm birth was 2.664 (90% CI 1.064, 6.673) times greater than the odds of full-term birth. No statistically significant associations were observed between stress, discrimination, and either preterm birth or telomere length. CONCLUSIONS: Maternal peripheral blood telomere shortening is associated with preterm birth, providing support to further explore the clinical utility of maternal telomere testing for prediction and early intervention of preterm birth and the study of biological mechanisms of spontaneous preterm birth.
RESUMEN
OBJECTIVES: Black mothers experience markedly disproportionate maternal morbidity and mortality in the United States, with racism often cited as the root cause manifesting through several pathways. The study examined Black mothers' perceived provider communication, support needs, and overall experiences in the neonatal intensive care unit (NICU). DESIGN: This study used grounded theory embedded in the Black feminist theoretical (BFT) framework to generate new ideas grounded in the data. Data was collected through semi-structured interviews using videoconferencing, with questions related to the mother's overall NICU experiences, communication within the NICU, and perceived support needs. Data were analyzed using thematic analysis. RESULTS: Twelve mothers participated in the study; most were married (n = 10), had a cesarean birth, had a previous pregnancy complication (e.g., diabetes, hypertension), had attained a graduate degree or more (n = 9), earned an annual household income of $75,000 or more, and were between 35-44 years of age (n = 7). Three broad domains with several accompanying themes and sub-themes were identified, explicating the mother's experiences in the NICU. Specifically, factors influencing NICU hospitalization for mothers included maternal care/nursing experiences, interactions in the NICU, and the perceived support need that might attenuate negative care and birthing experiences. . CONCLUSION: The study adds to the growing literature championing Black maternal health equity and multilevel quality improvement strategies to foster equitable maternal health. Our study reinforces the need for racially congruent interventions and policy reformations to protect Black birthing people regardless of socioeconomic factors and social class using life course, holistic approaches, and intersectionality mindset. Importantly, using the BFT, this study calls for culturally sensitive research to capture the nuances associated with the multiplicity of experiences of Black people.

BACKGROUND: The association of maternal exposure to selective serotonin reuptake inhibitors (SSRIs) or serotonin and norepinephrine reuptake inhibitors (SNRIs) with the risk of system-specific congenital malformations in offspring remains unclear. We conducted a meta-analysis to examine this association and the risk difference between these two types of inhibitors. METHODS: A literature search was performed from January 2000 to May 2023 using PubMed and Web of Science databases. Cohort and case-control studies that assess the association of maternal exposure to SSRIs or SNRIs with the risk of congenital abnormalities were eligible for the study. RESULTS: Twenty-one cohort studies and seven case-control studies were included in the meta-analysis. Compared to non-exposure, maternal exposure to SNRIs is associated with a higher risk of congenital cardiovascular abnormalities (pooled OR: 1.64 with 95% CI: 1.36, 1.97), anomalies of the kidney and urinary tract (pooled OR: 1.63 with 95% CI: 1.21, 2.20), malformations of nervous system (pooled OR: 2.28 with 95% CI: 1.50, 3.45), anomalies of digestive system (pooled OR: 2.05 with 95% CI: 1.60, 2.64) and abdominal birth defects (pooled OR: 2.91 with 95%CI: 1.98, 4.28), while maternal exposure to SSRIs is associated with a higher risk of congenital cardiovascular abnormalities (pooled OR: 1.25 with 95%CI: 1.20, 1.30), anomalies of the kidney and urinary tract (pooled OR: 1.14 with 95%CI: 1.02, 1.27), anomalies of digestive system (pooled OR: 1.11 with 95%CI: 1.01, 1.21), abdominal birth defects (pooled OR: 1.33 with 95%CI: 1.16, 1.53) and musculoskeletal malformations (pooled OR: 1.44 with 95%CI: 1.32, 1.56). CONCLUSIONS: SSRIs and SNRIs have various teratogenic risks. Clinicians must consider risk-benefit ratios and patient history when prescribing medicines.

The American College of Medical Genetics and Genomics (ACMG) recommends carrier screening for all pregnant women regardless of race or ethnicity. In recent years, the ACMG broadened the guidelines to include expanded carrier screening (ECS) which can screen for 112 conditions. This study seeks to explore the perceptions of pregnant Latina women about the benefits and concerns related to ECS use. Partnering with prenatal clinics in Texas, we conducted semi-structured qualitative interviews with 32 pregnant Latina women in their second or third trimester of pregnancy. NVivo 8 was used to conduct content analysis and emergent coding of the data. Participants reported the benefits of ECS as helping them prepare for the baby's arrival, informing them of the baby's risk for genetic conditions, ensuring the health of their baby, and preventing diseases before birth. The ECS-related concerns expressed by the participants included worries surrounding potential positive ECS results, insufficient knowledge about the genetic diseases screened for by ECS, the accuracy of the ECS, the potential harm ECS may cause the baby, and the affordability of ECS. After weighing both their perceived benefits and concerns, nearly all the participants believed that ECS should be offered to all pregnant women. This study contributes to an understudied research area in the genetic/genomic field. Our findings can help increase the awareness of obstetricians, genetic professionals, and other healthcare providers regarding pregnant Latina women's views on ECS and inform the design of culturally appropriate care as ECS is adopted into routine clinical practice.
RESUMEN
Integrated behavioral health can improve primary care and mental health outcomes. Access to behavioral health and primary care services in Texas is in crisis because of high uninsurance rates, regulatory restrictions, and lack of workforce. To address gaps in access to care, a partnership formed among a large local mental health authority in central Texas, a federally designated rural health clinic, and the Texas A&M University School of Nursing to create an interprofessional team-based health care delivery model led by nurse practitioners in rural and medically underserved areas of central Texas. Academic-practice partners identified 5 clinics for an integrated behavioral health care delivery model. From July 1, 2020, through December 31, 2021, a total of 3183 patient visits were completed. Patients were predominantly female (n = 1719, 54%) and Hispanic (n = 1750, 55%); 1050 (33%) were living at or below the federal poverty level; and 1400 (44%) were uninsured. The purpose of this case study was to describe the first year of implementation of the integrated health care delivery model, barriers to implementation, challenges to sustainability, and successes. We analyzed data from multiple sources, including meeting minutes and agendas, grant reports, direct observations of clinic flow, and interviews with clinic staff, and identified common qualitative themes (eg, challenges to integration, sustainability of integration, outcome successes). Results revealed implementation challenges with the electronic health record, service integration, low staffing levels during a global pandemic, and effective communication. We also examined 2 patient cases to illustrate the success of integrated behavioral health and highlighted lessons learned from the implementation process, including the need for a robust electronic health record and organizational flexibility.

With the advance of genetic technologies, the use of expanded carrier screening (ECS) in the prenatal setting is growing. ECS tests for a wide range of inherited genetic disorders regardless of racial/ethnic background and family history. Latinxs are an important ECS stakeholder group as they are the largest minority group with the highest fertility rate in the United States. Yet, the Latinx population has, to date, been underrepresented and understudied in genetics/genomics research. We conducted a study to explore the knowledge and perspectives of pregnant Latinas regarding ECS in which descriptive statistics and content analysis were used to analyze the data. Thirty-two pregnant Latinas - mostly of low educational levels (no education beyond high school) and with less than $20,000 annual household income living in rural areas were surveyed, provided with education about ECS, and interviewed. Participants were found to possess limited knowledge about ECS prior to being interviewed. Most (68.8%), however, expressed interest in pursuing ECS following the educational component that explained ECS. Their interest was mainly driven by the desire to know their baby's chance of developing a genetic disorder, the low risk of ECS procedures for both pregnant Latinas and their fetus, and the opportunity to better prepare for raising a child with a genetic condition. Our findings contribute to the limited research in the genetics/genomics field by providing in-depth insights into the perspectives of pregnant Latinas regarding ECS. Obstetric providers and genetic counselors should provide culturally appropriate education and counseling to empower pregnant Latinas to make informed decisions about the use of ECS.

PURPOSE: There are, currently, conflicting opinions about the adoption of exome sequencing (ES) into the standard newborn screening program. This study aimed to explore the views of pregnant Latinas, a hard-to-reach, underserved, and understudied population, about pursuing ES for their newborns. METHODS: We conducted semistructured interviews with 32 pregnant Latinas who predominately lived in rural areas and had low levels of income and education. An emergent coding approach was used to analyze the qualitative data collected. RESULTS: Our entire sample believed that ES should be offered as a part of newborn screening, which could empower pregnant Latinas to better understand their children's health and take early treatment actions. Although some participants were concerned about potentially bad ES results and had questions about the accuracy of ES results, nearly all interviewees reported that they would be willing to have their newborns undergo ES. The main reasons given were to be informed of diseases that the baby may have, and the perception that ES is a procedure that involves minimal risk. CONCLUSION: Pregnant Latinas in this study had favorable attitudes toward newborn ES. Their perspectives should be considered when decisions are made about incorporating ES into newborn screening.

BACKGROUND: The development of brain metastases (BM) is one of the most feared complications of cancer due to the substantial neurocognitive morbidity and a grim prognosis. In the past decade, targeted therapies and checkpoint inhibitors have demonstrated promising intracranial response rates for tumors of multiple histologies. As overall survival for these patients improves, there is a growing need to identify issues surrounding patient survivorship and to standardize physician practice patterns for these patients. To date, there has not been an adequate study to specifically explore these questions of survivorship and practice standardization for patients with advanced cancer and BM. METHODS: Here, we present results from a cross-sectional survey in which we analyze responses from 237 patients, 209 caregivers, and 239 physicians to identify areas of improvement in the clinical care of BM. RESULTS: In comparing physician and patient/caregiver responses, we found a disparity in the perceived discussion of topics pertaining to important aspects of BM clinical care. We identified variability in practice patterns for this patient population between private practice and academic physicians. Many physicians continue to have patients with BM excluded from clinical trials. Finally, we obtained patient/physician recommendations on high-yield areas for federal funding to improve patient quality of life. CONCLUSION: By identifying potential areas of unmet need, we anticipate this wealth of actionable information will translate into tangible benefits for both patients and caregivers. Future studies are needed to validate our findings.
RESUMEN
BACKGROUND: Prenatal genetic testing is an essential part of routine prenatal care. Yet, obstetricians often lack the time to provide comprehensive prenatal genetic testing education to their patients. Pregnant women lack prenatal genetic testing knowledge, which may hinder informed decision-making during their pregnancies. Due to the rapid growth of technology, mobile apps are a potentially valuable educational tool through which pregnant women can learn about prenatal genetic testing and improve the quality of their communication with obstetricians. The characteristics, quality, and number of available apps containing prenatal genetic testing information are, however, unknown. OBJECTIVE: This study aims to conduct a firstreview to identify, evaluate, and summarize currently available mobile apps that contain prenatal genetic testing information using a systematic approach. METHODS: We searched both the Apple App Store and Google Play for mobile apps containing prenatal genetic testing information. The quality of apps was assessed based on the criteria adopted from two commonly used and validated mobile app scoring systems, including the Mobile Application Rating Scale (MARS) and the APPLICATIONS evaluation criteria. RESULTS: A total of 64 mobile apps were identified. Of these, only 2 apps were developed for a specific prenatal genetic test. All others were either pregnancy-related (61/64, 95%) or genetics-related (1/64, 2%) apps that provided prenatal genetic testing information. The majority of the apps (49/64, 77%) were developed by commercial companies. The mean quality assessment score of the included apps was 13.5 (SD 2.9), which was equal to the average of possible theoretical score. Overall, the main weaknesses of mobile apps in this review included the limited number of prenatal genetic tests mentioned; incomprehensiveness of testing information; unreliable and missing information sources; absence of developmental testing with users (not evidence based); high level of readability; and the lack of visual information, customization, and a text search field. CONCLUSIONS: Our findings suggest that the quality of mobile apps with prenatal genetic testing information must be improved and that pregnant women should be cautious when using these apps for prenatal genetic testing information. Obstetricians should carefully examine mobile apps before referring any of them to their patients for use as an educational tool. Both improving the quality of existing mobile apps, and developing new, evidence-based, high-quality mobile apps targeting all prenatal genetic tests should be the focus of mobile app developers going forward.

OBJECTIVES: Despite the obstacles of limited education and employment opportunities-and the stress associated with immigration and pregnancy-Mexican immigrant women have low rates of preterm birth (PTB) compared to the US national average for all races and ethnicities. Stressors during pregnancy, and stressors associated with acculturation, may accelerate cellular aging manifested by shortened telomere length (TL) in pregnant women. Our objectives were to: (1) determine whether women with PTBs had shorter telomere lengths compared to women who had full term births; (2) assess the association of acculturation with TL and PTB. METHODS: This prospective pilot study collected data from 100 self-identified Mexican-origin pregnant women. Survey data included self-administered sociodemographic and acculturation measures and was collected from participants via paper and pen, while biologic data was collected via a single blood draw during a regularly scheduled prenatal visit between 26 and 36 weeks gestation. PTB data was collected from the participant's medical record after delivery. RESULTS: TL was significantly associated with PTB; the median TL of the women with PTB was less than the median TL for the full sample (p = 0.02). Based on regression analysis for PTB vs acculturation, we found no significant associations between acculturation and PTB or TL. CONCLUSIONS FOR PRACTICE: This study provides important evidence of the association between shortened maternal TL and adverse birth outcomes. By linking social, clinical and biologic data, we can enhance our understanding of social determinants that may affect racial and ethnic disparities in preterm birth.

PURPOSE: The COVID-19 pandemic has disrupted health care delivery and services around the world causing rapid changes to maternity care protocols and pregnant women to give birth with tight restrictions and significant uncertainties. There is a gap in evidence about expectant and new mothers' experiences with birthing during the pandemic. We sought to describe and understand pregnant and new mothers' lived experiences during the COVID-19 pandemic using authentic birth stories. STUDY DESIGN AND METHODS: Using a narrative analysis framework, we extracted relevant YouTube birth stories using predetermined search terms and inclusion criteria. Mothers' birth stories were narrated in their second or third trimester or those who had recently given birth during the pandemic. Birth stories were analyzed using an inductive and deductive approach to capture different and salient aspects of the birthing experience. RESULTS: N = 83 birth stories were analyzed. Within these birth stories, four broad themes and 13 subthemes were identified. Key themes included a sense of loss, hospital experiences, experiences with health care providers, and unique experiences during birth and postpartum. The birth stories revealed that the COVID-19 pandemic brought unexpected circumstances, both positive and negative, that had an impact on mothers' overall birthing experience. CLINICAL IMPLICATIONS: Results provided a detailed description of women's lived experience with giving birth during the COVID-19 pandemic. Maternity nurses should try to provide clear communication and compassionate patient-centered care to relieve women's anxieties about uncertain and unpredictable policy changes on COVID-19 as the pandemic continues to evolve.

One in four women has experienced intimate partner violence in their lifetimes. The effects of intimate partner violence on women's mental health may be long-term; possible conditions include post-traumatic stress disorder, depression, and anxiety. Latina women may be particularly vulnerable to long-term effects of intimate partner violence. The purpose of this study was to describe Latina women's experiences in long-term support groups for survivors of intimate partner violence. Forty-nine Latina women were interviewed about their experiences in a nurse-led long-term support group, with participation from 2 months to 9 years. The women ranged in age from 26 to 73 years and all but two interviews were in Spanish. Five themes emerged from the qualitative data: awakening, transformation, community, empowerment, and advocate. Women described their thoughts of still feeling the 'ugliness of the abuse', even years after it occurred with some women enduring abuse for as long as 32 years. The need for long-term support groups was evident as women described the value of the group for providing support and gaining an understanding that they are not alone, or their awakening to the idea that they can have a life without abuse. Long-term support groups give voice to Latina women who are survivors of intimate partner violence. By raising their awareness and sense of community, women survivors can be transformed and empowered to improve their lives and advocate for others who face similar struggles.

Pregnant Hispanic women are underserved with their needs for genetic counseling, despite birth defects remaining the leading cause of infant death in the United States. We present the qualitative findings of a study to understand knowledge and perceptions of prenatal testing in a sample of hard-to-reach underrepresented Hispanic pregnant women in South Texas. The sample for this study was 10 Hispanic pregnant women who were recruited from a high-risk prenatal clinic in South Texas in 2019. The semi-structured interview questions were created based on the researchers' clinical experiences with this population and were designed to examine knowledge and perceptions of participants toward prenatal testing. Analysis of the qualitative data yielded several themes related to prenatal testing: (a) knowledge, (b) confusion, (c) partner's and support persons' opinions, (d) information sharing from providers, (e) psychological benefits, (f) preparation for baby, (g) obstacles, (h) religious influence, and (i) educational tools to assist with understanding. Women's understanding and knowledge of prenatal testing was limited, specifically regarding its purpose, how it works, the benefits, and why it was recommended by their provider. Lack of clarity about why they should take the test and its risks for them and their babies was perceived as something that could impede their acceptance of prenatal testing. All participants agreed that healthcare providers should share more information about prenatal testing in a way that uses 'everyday language' so that they can understand it better. All respondents mentioned that prenatal testing provides information about their baby's health conditions, alleviates their stress and concerns, and psychologically prepares them and their family for what is to come. Identifying ways to increase culturally appropriate education delivered by genetic counselors such as through the adoption of telemedicine and mobile technology can help fill the gap for this underserved population.

INTRODUCTION: Explanations for racial disparities in preterm birth (PTB) are elusive, especially when comparing high rates in some racial groups with low rates in Mexican-immigrant women. The purpose of this study was to examine potential protective factors against PTB such as religiosity and acculturation. METHODS: This study was a prospective investigation of Mexican- and U.S.-born pregnant women. Women were recruited from a low-income-serving prenatal clinic in Texas. Survey instruments included socioeconomic variables, acculturation, and religiosity/spirituality (R/S). Logistic regression was used to examine the associations between acculturation, religiosity, and PTB. Because of the low prevalence of PTB in our sample, we were not able to adjust for confounding characteristics. RESULTS: Ninety-one low-income women, mostly Mexican immigrants, participated in the study. PTB in our sample was lower than the national average in the United States (5.5% vs. 9.9%) and was positively but moderately associated with high R/S. R/S scores were high, particularly for frequency of attendance, prayer, and religious coping. Women with lower acculturation had higher scores on the religiosity measures. CONCLUSION: Further research is needed with a larger sample to include other ethnic and racial minorities to more fully understand the relationships between acculturation, religiosity, and PTB.

The resurgence of interest in the influence of religion and spirituality on health is examined within the context of the holistic paradigm and historical connection between nursing and spirituality. While nursing and spirituality often intersect with end-of-life considerations, this article presents findings from studies that demonstrate that religious involvement favors health and longevity across the life course. Examples include protective associations with stress, depression, self-rated health, and infant birth weight. Theoretical and empirical explanations for this relationship are offered, such as social and psychological resources and healthy behaviors. The effects of religion on biological functioning, including allostatic load and telomere length, are also discussed, although this area is understudied. Considerations for the "dark-side" of religious involvement are also offered. Suggestions for nurses wishing to protect and promote the health of their patients using a holistic approach include expanding knowledge of research on religion and health and advocating for patients' spiritual needs by conducting a comprehensive spiritual assessment in primary, secondary, and tertiary clinical settings.

AIM: We explored faculty and staff perceptions of the challenges and opportunities of working on regional campuses of a large academic health science center. BACKGROUND: The growth of multicampus academic institutions presents numerous issues for intercampus planning and for organizational/professional relationships. We were interested in learning how regional campus faculty and staff experienced these issues, with the practical goal of making recommendations to both central and regional campus administrations. METHOD: A cross-sectional, online survey was distributed to faculty and staff who worked at regional campuses of a large health sciences university. RESULTS: Regional faculty and staff felt more valued by local colleagues and administrators than by their central campus counterparts. Top challenges were central administration's lack of communication and understanding of regionals' unique circumstances and needs. CONCLUSION: Regional campuses' workplace experience is significantly different from that of central campus. More timely communication and active solicitation of regional campus input are needed.

Despite widened access to HIV testing, around half of those infected worldwide are unaware of their HIV-positive status and linkage to care remains a major challenge. Current rapid HIV tests are typically analogue risking incorrect interpretation, no facile electronic data capture, poor linkage to care and data loss for public health. Smartphone-connected diagnostic devices have potential to dramatically improve access to testing and patient retention with electronic data capture and wireless connectivity. We report a pilot clinical study of surface acoustic wave biosensors based on low-cost components found in smartphones to diagnose HIV in 133 patient samples. We engineered a small, portable, laboratory prototype and dual-channel biochips, with in-situ reference control coating and miniaturised configuration, requiring only 6 µL plasma. The dual-channel biochips were functionalized by ink-jet printing with capture coatings to detect either anti-p24 or anti-gp41 antibodies, and a reference control. Biochips were tested with 31 plasma samples from patients with HIV, and 102 healthy volunteers. SH-SAW biosensors showed excellent sensitivity, specificity, low sample volumes and rapid time to result, and were benchmarked to commercial rapid HIV tests. Testing for individual biomarkers found sensitivities of 100% (anti-gp41) and 64.5% (anti-p24) (combined sensitivity of 100%) and 100% specificity, within 5 min. All positive results were recorded within 60 s of sample addition with an electronic readout. Next steps will focus on a smartphone-connected device prototype and user-friendly app interface for larger scale evaluation and field studies, towards our ultimate goal of a new generation of affordable, connected point-of-care HIV tests.
RESUMEN
Latina immigrant women are vulnerable and may experience higher levels of interpersonal or intimate partner violence (IPV) due to their immigrant status and cultural emphasis on familism. The concept of empowerment within the cultural context of Latina immigrant women experiencing IPV was analyzed using a modified version of Walker and Avant's concept analysis technique. The technique considers usage and definitions in the literature, antecedents, attributes, empirical referents, and the inclusion of a model and contrary case. This analysis encompasses a comparative approach and includes a discussion of how the definition of empowerment compares across the nursing literature. Defining attributes include reciprocal relationships, autonomy, and accountability. Antecedents comprise willingness to learn and motivation to create change. Consequences encompass self-esteem, self-efficacy, and competence for making life decisions. Empowerment has the potential to improve total well-being, having a positive and profound impact on the lives of women experiencing IPV.

Although research has documented factors associated with maternal smoking, we need a more in-depth understanding of the risk factors associated with changes in smoking behaviors during the postpartum period. We investigate smoking patterns during pregnancy and 1 year postpartum as a function of relevant psychosocial factors. We use data on 3,522 postpartum mothers from the Fragile Families and Child Wellbeing Study to analyze the predictors of smoking among mothers who did not smoke during pregnancy but smoked at 1 year postpartum, mothers who smoked both during pregnancy and postpartum, and mothers who did not smoke during either period. Our covariates are grouped into four categories of risk factors for smoking: socioeconomic status, health care, life course and health, and partner and social support. Postpartum mothers in our sample were more likely to smoke throughout or after their pregnancies if they had only a high school education or less, had a household income three or more times below the poverty line, had public or no health insurance, breastfed for less than 5 months, were not married to the infant's father, if the infant's father currently smoked, and if they attended religious services less than once a week. Mental health problems were consistently associated with an increased risk of constant and postpartum smoking relative to non-smoking. Psychosocial factors play a role in postpartum smoking, but they have a stronger effect in predicting smoking that persists throughout pregnancy and the first year postpartum.
