Association of Gut Microbiota With Fatigue in Black Women With Polycystic Ovary Syndrome

Background Fatigue is a highly prevalent symptom for individuals with polycystic ovary syndrome (PCOS); however, characterization of fatigue and investigation into the gut microbiome—a pathway that may contribute to fatigue—remains inadequately explored in Black women with PCOS. Objectives The purpose of this cross-sectional study was to examine fatigue and its relationship to the gut microbiome in adult Black women with PCOS. Methods Adult Black women with a diagnosis of PCOS were recruited for this cross-sectional study. The Multidimensional Fatigue Inventory-20 (MFI-20) and the PROMIS Fatigue Short Form were used to measure fatigue. The V3/V4 region of the bacterial 16S rRNA gene was sequenced to investigate gut microbial composition. Relative abundance and diversity values were calculated. Results We found that Black women with PCOS experience mild to moderate levels of fatigue. An inverse relationship between fatigue scores and alpha diversity values was found for the gut microbiome. We also found distinct beta diversity profiles based on fatigue. Lastly, when controlling for hypertension and body mass index, Ruminococcus bromii, Blautia obeum, Roseburia, and HT002 were associated with three subscales of the MFI-20. Discussion Black women with PCOS experience mild to moderate fatigue. Clinicians should be cognizant of this population’s increased risk for fatigue to adequately address their healthcare needs. We also found that gut microbial composition was associated with fatigue in Black women with PCOS. Specifically, a higher relative abundance of certain gut bacteria involved in short-chain fatty acid production and anti-inflammatory pathways was correlated with lower fatigue levels. Future studies should further investigate the link between the gut microbiome and fatigue to determine whether this relationship is causal as better insight could inform tailored diet and exercise interventions to alter the gut microbiome and reduce fatigue.

Comparison of Weighting Methods to Understand Improved Outcomes Attributable to Public Health Nursing Interventions

Background The complex work of public health nurses (PHNs) specifically related to mental health assessment, intervention, and outcomes makes it difficult to quantify and evaluate the improvement in client outcomes attributable to their interventions. Objectives We examined heterogeneity across parents of infants served by PHNs receiving different interventions, compared the ability of traditional propensity scoring methods versus energy-balancing weight (EBW) techniques to adjust for the complex and stark differences in baseline characteristics among those receiving different interventions, and evaluated the causal effects of the quantity and variety of PHN interventions on client health and social outcomes. Methods This retrospective study of 4,109 clients used existing Omaha System data generated during the routine documentation of PHN home visit data. We estimated the effects of intervention by computing and comparing weighted averages of the outcomes within the different treatment groups using two weighting methods: (a) inverse probability of treatment (propensity score) weighting and (b) EBWs. Results Clients served by PHNs differed in baseline characteristics with clients with more signs/symptoms. Both weighting methods reduced heterogeneity in the sample. EBWs were more effective than inverse probability of treatment weighting in adjusting for multifaceted confounding and resulted in close balance of 105 baseline characteristics. Weighting the sample changed outcome patterns, especially when using EBWs. Clients who received more PHN interventions and a wider variety of them had improved knowledge, behavior, and status outcomes with no plateau over time, whereas the unweighted sample showed plateaus in outcomes over the course of home-visiting services. Discussion Causal analysis of PHN-generated data demonstrated PHN intervention effectiveness for clients with mental health signs/symptoms. EBWs are a promising tool for evaluating the true causal effect of PHN home-visiting interventions.

Influence of Preterm Birth and Environmental Context on Academic Performance and Neurodevelopmental Outcomes

Background Preterm birth affects 10% of all births annually in the United States. Outcomes of people born preterm are challenging to predict because of multiple influences, including gestational age, birth weight, and social and environmental contexts, that contribute to an individual’s growth and developmental trajectory. The influence of toxic stress is underrepresented in the literature assessing preterm birth outcomes. Objectives The current analyses use the eco-bio-developmental model of poverty and preterm birth as a framework to model the pathways among toxic stress, preterm birth, and neurodevelopmental outcomes. Poverty and toxic stress were hypothesized to increase the risk for impaired neurodevelopmental and academic outcomes—both directly and indirectly. Methods The analytic sample of 55,873 children aged 6–17 years was derived from the National Survey of Children’s Health 2020–2021. Structural equation models with combined measurement and path models for each dependent variable were constructed using latent toxic stress variables. The structural path equations included direct paths from the latent measure of prenatal toxic stress, preterm birth status, and the latent measure of childhood toxic stress to the neurodevelopmental outcome, as well as an indirect, mediated path from prenatal toxic stress through preterm birth status to the outcome. Results Across models, higher levels of prenatal toxic stress were significantly associated with preterm birth and lower birth weight ranges. Preterm low birth weight status was associated with a greater likelihood of neurodevelopmental impairment, repeating a grade, and special education plans. The predicted probabilities of neurodevelopmental impairment, repeating grades, and special education plans are significantly higher with above-average levels of exposure to prenatal and childhood toxic stress. Discussion There is a need for prospective studies that assess predictors and outcomes of preterm birth that are stratified by gestational age and consider the timing, chronicity, and influence of toxic stress and environmental exposures. There is an imperative for public health programs and policies designed to support families, caregivers, and children to address the individual and structural social determinants of health that contribute to toxic stress, thereby increasing preterm birth rates and negatively affecting the outcomes of children born preterm.

Factors Affecting Research Participation Among Specialist Dementia Nurses

Background Research involvement and engagement is a vital aspect of nursing practice. However, research in dementia care remains limited compared to research focused on finding a cure, presenting a significant gap that specialist dementia nurses (Admiral Nurses) can help bridge by participating in research themselves and facilitating recruitment to research. Objectives This study aimed to assess the research involvement and support needs of Admiral Nurses and identify factors affecting their participation in research. This research is particularly timely as Dementia UK has launched its first research strategy, which necessitates strengthening research capacity within Admiral Nursing. Methods We used a mixed methods convergent parallel synthesis design, simultaneously collecting quantitative and qualitative data. An online survey was conducted in January 2023, targeting current Admiral Nurses across the United Kingdom. The survey included questions addressing demographics, research experience, goals, barriers, facilitators, and support needs. Data analysis involved descriptive statistics, frequencies, univariate analyses, and thematic analysis. Results A positive relationship was found between the highest level of academic achievement and current or previous research involvement, as well as interest in becoming involved in research in the future. Although most nurses recognized the importance of research, only half reported current or past research involvement, indicating a need for increased support. A lack of access and opportunities for peer discussion hindered engagement with research findings. Time constraints, lack of support, and low confidence were major barriers to research involvement. Support needs varied but included mentorship, coaching, and the potential for a community of practice for research. Discussion This survey of Admiral Nurses sheds light on their research involvement, support needs, and barriers to participation. Recognizing the significance of research while identifying challenges and support requirements is crucial for enhancing research capacity among these specialized nurses. This study contributes valuable insights into the world of specialist dementia nursing and lays the foundation for future strategies to increase research engagement in this field.

Systematic Review and Meta-Analysis of Psychological Distress and Acute Exacerbation of Chronic Obstructive Pulmonary Disease and Consequences

Background People with chronic obstructive pulmonary disease (COPD) occasionally develop acute exacerbation of COPD—a potentially fatal condition. Psychological distress was associated with acute exacerbation of COPD. However, the evidence on the effect of psychological distress on acute exacerbation of COPD remains unclear. Objective The aim of this study was to explore the influence of psychological distress on acute exacerbation of COPD and its consequences. Methods The current review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using three databases (PubMed, CINAHL, and PsyINFO) that were searched to identify relevant articles. Pooled risk ratios and 95% confidential interval were calculated from the included studies’ data with random-effect methods to estimate the effect of psychological distress on acute exacerbation of COPD and its consequences. Results Nineteen articles were included in the review. Most revealed that psychological distress was significantly associated with increased risk of acute exacerbation of COPD and its consequences. The meta-analyses showed that psychological distress increased risk of acute exacerbation of COPD, COPD-related hospitalization, and death. Conclusion Psychological distress had negative effects on acute exacerbation of COPD and its consequences. The results of the meta-analyses show that persons with COPD and psychological distress had a greater risk of acute exacerbation of COPD, hospitalization, and death.

Methodology for Analyzing Qualitative Data in Multiple Languages

Background Translation strategies are commonly used for qualitative interview data to bridge language barriers. Inconsistent translation of interviews can lead to conceptual inequivalence, where meanings of participants' experiences are distorted, threatening scientific rigor. Objectives Our objective is to describe a systematic method developed to analyze multilingual, qualitative interview data while maintaining the original language of the transcripts. Methods A literature review of translation strategies, cross-language, and multilingual qualitative research was conducted. Combined with criteria for qualitative content analysis and trustworthiness, the methodology was developed and used for a qualitative descriptive study. Results The study had interview data in both English and Spanish. The research team consisted of both native Spanish and English speakers, who were grouped based on language. Verbatim transcription of data occurred in the original languages. All codes were kept in English, allowing the research team to view the data set as a whole. Two researchers within each group coded each transcript independently before reaching a consensus. The entire research team discussed all transcripts, and finally, major themes were determined. Participants' quotes remained in the original language for publication, with an English translation included when needed. Discussion Analyzing transcripts in the original language brought forth cultural themes that otherwise may have been overlooked. This methodology promotes conceptual equivalence and trustworthiness that is paramount in cultural, linguistic, and social determinants of health research to advance health equity.
