Association between multisite musculoskeletal pain and disability trajectories among community-dwelling older adults.

BACKGROUND: Pain is linked to disability, but how multisite musculoskeletal pain leads to disability over time is not well elaborated. OBJECTIVE: To examine the associations of multisite musculoskeletal pain with disability among a nationally representative cohort. DESIGN: We used data from the National Health and Aging Trends Study (NHATS) 2015-22. Disability was assessed by basic activities of daily living (ADL) and instrumental activities of daily living (IADL). PARTICIPANTS: A total of 5557 individuals with multisite musculoskeletal pain dwelling in the community were included in this study. METHODS: Group-based trajectory models were applied to identify distinct profiles of disability in ADL and IADL. Design-based logistic regressions were used to examine associations among multisite musculoskeletal pain, disability, and dual trajectory group memberships, adjusted for sociodemographic, health status, behavioral, and mental characteristics. RESULTS: Persons who experienced multisite musculoskeletal pain were at higher risk of disability in ADL and IADL. We identified five heterogeneous disability trajectories and named them based on baseline levels and rates of increase over time. Approximately, 52.42% of older adults with multisite musculoskeletal pain were in trajectories with ADL and IADL declines, and 33.60% experienced a rapid decline. Multisite musculoskeletal pain was associated with elevated relative risk for the adverse disability trajectories, which generally increases with multisite musculoskeletal pain frequency and number of sites. CONCLUSIONS: Persons with multisite musculoskeletal pain had a higher risk of disability. It is essential to adopt effective pain management strategies to maintain the independent living ability of older adults and to realize active aging.

Multi-Omics Analysis of Gut Microbiota and Host Transcriptomics Reveal Dysregulated Immune Response and Metabolism in Young Adults with Irritable Bowel Syndrome.

The integrated dysbiosis of gut microbiota and altered host transcriptomics in irritable bowel syndrome (IBS) is yet to be known. This study investigated the associations among gut microbiota and host transcriptomics in young adults with IBS. Stool and peripheral blood samples from 20 IBS subjects and 21 healthy controls (HCs) collected at the baseline visit of an RCT were sequenced to depict the gut microbiota and transcriptomic profiles, respectively. The diversities, composition, and predicted metabolic pathways of gut microbiota significantly differed between IBS subjects and HCs. Nine genera were significantly abundant in IBS stool samples, including Akkermansia, Blautia, Coprococcus, Granulicatella, Holdemania, Oribacterium, Oscillospira, Parabacteroides, and Sutterella. There were 2264 DEGs found between IBS subjects and HCs; 768 were upregulated, and 1496 were downregulated in IBS participants compared with HCs. The enriched gene ontology included the immune system process and immune response. The pathway of antigen processing and presentation (hsa04612) in gut microbiota was also significantly different in the RNA-seq data. Akkermansia, Blautia, Holdemania, and Sutterella were significantly correlated with ANXA2P2 (upregulated, positive correlations), PCSK1N (downregulated, negative correlations), and GLTPD2 (downregulated, negative correlations). This study identified the dysregulated immune response and metabolism in IBS participants revealed by the altered gut microbiota and transcriptomic profiles.

Pain/Stress, Mitochondrial Dysfunction and Neurodevelopment in Preterm Infants.

Introduction Preterm infants experience tremendous early life pain/stress during their neonatal intensive care unit (NICU) hospitalization, which impacts their neurodevelopmental outcomes. Mitochondrial function/dysfunction may interface between perinatal stress events and neurodevelopment. Nevertheless, the specific proteins or pathways linking mitochondrial functions to pain-induced neurodevelopmental outcomes in infants are remain unidentified. Our study aims to investigate the associations among pain/stress, proteins associated with mitochondrial function/dysfunction, and neurobehavioral responses in preterm infants. Methods We conducted a prospective cohort study, enrolling 33 preterm infants between September 2017 and July 2022 at two affiliated NICUs located in Hartford and Farmington, CT. NICU Network Neurobehavioral Scale (NNNS) datasets were evaluated to explore potential association with neurobehavioral outcomes. The daily pain/stress experienced by infant's during their NICU stay was documented. At 36-38 weeks post-menstrual age (PMA), neurobehavioral outcomes were evaluated using the NNNS and buccal swabs were collected for further analysis. Mass spectrometry-based proteomics was conducted on epithelial cells obtained from buccal swabs to evaluate protein expression level. Lasso statistical methods were conducted to study the association between protein abundance and infants' NNNS summary scores. Multiple linear regression and Gene Ontology (GO) enrichment analyses were performed to examine how clinical characteristics and neurodevelopmental outcomes may be associated with protein levels and underlying molecular pathways. Results During NICU hospitalization, preterm premature rupture of membrane (PPROM) were negatively associated with neurobehavioral outcomes. The protein functions including leptin receptor binding activity, glutathione disulfide oxidoreductase activity and response to oxidative stress, lipid metabolism, phosphate and proton transmembrane transporter activity were negatively associated with neurobehavioral outcomes, in the contrast, cytoskeletal regulation, epithelial barrier and protection function were found to be associated with the optimal neurodevelopmental outcomes. In addition, mitochondrial function associated proteins including SPRR2A, PAIP1, S100A3, MT-CO2, PiC, GLRX, PHB2, and BNIPL-2 demonstrated positive association with favorable neurodevelopmental outcomes, while proteins of ABLIM1, UNC45A, Keratins, MUC1, and CYB5B showed positive association with adverse neurodevelopmental outcomes. Conclusion Mitochondrial function-related proteins were observed to be associated with early life pain/stress and neurodevelopmental outcomes in infants. Large-scale studies with longitudinal datasets are warranted. Buccal proteins could be used to predict potential neurobehavioral outcomes.

"They're scared that somebody's gonna judge them": Female African American youth in foster care's perspectives on sexual and reproductive health communication with caregivers.

BACKGROUND: Obtaining accurate information is critical for youth's sexual and reproductive health (SRH). Youth not in foster care often learn about SRH from their biological parents. Separated from their biological parents, youth in care depend on healthcare providers and caregivers for SRH information. However, they often receive insufficient information and feel unsupported in meeting their needs for SRH information. PURPOSE: This study explored female African American adolescents in foster care's perspectives on effective SRH communication with caregivers to help them avoid sexual risks. METHODS: A qualitative study was conducted using semi-structured interviews. We used purposive sampling to recruit 16 adolescents aged 18 to 20 years old with a history of foster care placement. The transcribed interviews underwent inductive thematic analysis. The Positive Youth Development theory underpinned this research. RESULTS: Two prominent themes emerged: establishing a relationship and preferred communication approach. Youth reported that for caregivers to engage in effective SRH communication, they must first establish a relationship by being aware of the youth's childhood trauma, building trust, having patience, and being vulnerable. Youth also appreciated caregivers who ensured comfortability and were honest and straightforward. DISCUSSION: Caregivers should be trained on adverse childhood experiences, trauma-informed approaches, SRH knowledge, and communication. IMPLICATIONS TO PRACTICE: Healthcare providers should make use of the time spent with youth and discuss SRH topics during clinical encounters. This time spent with youth may be their only chance to obtain accurate SRH information. Youth's perspectives regarding communication about SRH should be implemented in future SRH communication interventions.

Work-health balance of cancer survivors returning to work: A meta-ethnography.

PURPOSE: This meta-ethnography investigates the multifaceted health-related experiences of cancer survivors returning to work (RTW), recognizing the pivotal role of employment in overall well-being, particularly in the context of increasing cancer cases among working-age adults. METHOD: Following the methodology of Noblit and Hare, a comprehensive literature search was conducted from 2013 to 2023 in databases including PubMed, Scopus, CINAHL, PsycINFO, and Embase. Qualitative studies assessing cancer survivors' experiences, motivation, concern, resilience, and need in the process of RTW were identified. Eligible studies were assessed for quality using the Critical Appraisal Skills Program Checklist, and their findings were subsequently synthesized. RESULTS: Seventeen studies were included for analysis. The finding revealed five key themes: motivations (voluntary and involuntary), cancer-related concerns, resilience, needs for cancer healthcare support, and workplace accommodation. Voluntarily RTW was primarily linked to desires of normalcy, while involuntary RTW was often financially driven. Cancer survivors often face physical, psychological, and social challenges in the RTW process. Resilience played a crucial role in their readaptation to the workplace. Participants expressed the need for additional guidance from healthcare providers and tailored support from the workplace to facilitate a smoother RTW experience. CONCLUSION: Cancer survivors aspire to be actively engaged, have their specific needs addressed, and achieve success in their return-to-work endeavors. Occupational guidance and accommodation from healthcare providers and employers play a pivotal role in empowering survivors to balance cancer and work, facilitating the return-to-work process, and enhancing the quality of survivorship.

COVID-19 mRNA vaccine, but not a viral vector-based vaccine, promotes neutralizing anti-type I interferon autoantibody production in a small group of healthy individuals.

Coronavirus disease 2019 (COVID-19) vaccines are highly effective but also induce adverse events, in particular, autoimmunity. Findings from several studies revealed that patients with life-threatening SARS-CoV-2 infection had increased, pre-existing, neutralizing antibodies against type I interferons (IFNs). However, whether COVID-19 vaccination induces the anti-type I IFN antibody remains unclear. In the current study, we evaluated plasma levels of 103 autoantibodies against various human self-antigens and 16 antibodies against viral antigens in healthy individuals pre- and post-COVID-19 vaccination. Twelve participants received a COVID-19 mRNA vaccine (Pfizer-BioNTech or Moderna), and 8 participants received a viral vector-based vaccine (Janssen). All participants produced increased antibody levels against SARS-CoV-2 antigens following vaccination. Among the 103 autoantibodies, only plasma levels of IgG autoantibodies against type I IFNs increased in participants who received a mRNA vaccine (3/12), but not in those who received the viral vector-based vaccine (0/8) at postvaccination compared to pre-vaccination. Among the three individuals showing increased anti-IFN IgG following vaccination, both plasma samples and plasma-purified total IgGs showed a dose-dependent binding ability to IFN-α; two of the three showed neutralizing activity to IFN-α-2a-induced phosphorated STAT1 responses in human peripheral blood mononuclear cells postvaccination compared to baseline in vitro. Among the 103 autoantibodies tested, the COVID-19 mRNA vaccine, but not the viral vector-based vaccine, specifically induced neutralizing anti-type I IFN autoantibodies in a small group of healthy individuals (~10%). Findings from this study imply that COVID-19 mRNA vaccines may suppress IFN-mediated innate immunity and impair immune defense through induced autoimmunity in some healthy individuals, who may need to switch to another type of COVID-19 vaccine (e.g., a viral vector-based vaccine).

Experiences of nurses managing parenthood and career. A systematic review and meta-synthesis.

AIM: Consolidate and synthesize evidence on working nurse-parent experiences of parenthood. BACKGROUND: Demands in healthcare strain the workforce, causing burnout and high turnover rates, especially among nurses. Balancing work and family responsibilites is even more challenging for nurse-parents. INTRODUCTION: Nursing is highly stressful, and the experiences of nurse-parents are under-researched highlighting the need to better understand and support nurse-parents in their dual roles. METHODS: Seven databases (PubMed, Embase, CINAHL, PsycINFO, ProQuest, Scopus, and Web of Science) were systematically searched for published and unpublished primary qualitative studies. Extracted data were meta-summarized and synthesized using Sandelowski and Barroso's approach. FINDINGS: Twelve peer-reviewed studies, conducted between 2007 and 2022, investigated the challenges faced by 339 female nurse-parents across various countries. The meta-synthesis revealed two main themes: (a) Clashes of dual roles, and (b) Accept, adapt, and compromise, which were supported by six subthemes. Nurse-parents struggled with dual roles, often neglected self-care, and experienced work-family conflicts. However, they learned to accept their situations, adapt by seeking help from family, friends, and colleagues, and compromise on career aspirations to prioritize their families. The importance of organizational support and flexibility in accommodating their dual roles was emphasized. DISCUSSION: Female nurse-parents face challenges in balancing their dual roles, resulting in fatigue, compromised self-care, and limited social interactions. The culture of self-sacrifice in nursing contributes to these challenges, impacting patient safety. Supportive interventions like mindfulness programs and exercise classes can promote well-being. Staffing shortages and shift work further affect the work-life balance for nurse-parents. CONCLUSION AND IMPLICATIONS FOR NURSING AND HEALTH POLICY: Creating a supportive work environment for nurse-parents is crucial. Family-friendly shifts revised parental leave policies, and improved childcare support are needed. Supporting nurse-parents benefits their well-being and enhances patient care. Collaboration between healthcare organizations and policymakers is essential to address workforce shortages and implement changes.

Pain sensation and gut microbiota profiles in older adults with heart failure.

Objectives: Patients with heart failure (HF) experience severe pain and may have altered pain sensation; however, the underlying mechanisms of these symptoms are not yet fully understood. Identifying pain sensation and genomic biomarkers of pain in older adults with HF is a critical step toward developing personalized interventions to improve pain management and outcomes. This study aimed to investigate the differences in pain sensation, gut microbiota, self-reported pain, and symptoms in older adults with and without HF. Methods: Twenty older adults with HF and age-matched healthy controls (HCs) were recruited in the Northeastern United States. Quantitative sensory testing and conditioned pain modulation were performed on the nondominant upper arm to detect the mechanical, thermal, and pressure pain thresholds and pain modulations. Stool samples were collected, and the 16S rRNA V4 gene region of stool samples was sequenced and processed using the Mothur 1.42.3 pipeline. Self-reported pain and symptoms were measured by the Brief Pain Inventory and the NIH Patient-reported Outcomes Measurement Information System. The associations between pain sensation, gut microbiota α-diversity indices, and pain and symptoms were explored using the Spearman correlations. Results: The HF and HC subjects' mean ages were 73.50 (SD = 8.33) and 67.10 (SD = 7.64), respectively. The HF subjects reported significantly higher pain intensity and interference, sleep disturbance, fatigue, anxiety, and depression than the HCs. The HF subjects also had a significantly lower level of physical function and participation in social roles and activities. Compared with the HCs, the HF subjects had significantly altered conditioned pain modulation heat effect and gut microbiota compositions and predicted metabolic functions. The Statistical Analysis Of Metagenomic Profiles indicated that the HF subjects had a significantly decreased cardiac muscle contraction pathway compared with the HCs. The correlation analysis showed that the quantitative sensory testing profiles and gut microbiota diversity index were significantly associated with pain and symptoms in older adults with HF. Conclusions: Older adults with HF had more severe self-reported pain and symptoms, altered pain sensation, and different gut microbiota composition and function compared with age-matched HCs. Pain sensation and gut microbiota may contribute to pain and symptoms in older adults with HF and could serve as biomarkers of pain and symptoms of HF. Further research with a larger sample size is warranted to confirm these findings.

Expression of fatty acid related gene promotes astaxanthin heterologous production in Chlamydomonas reinhardtii.

Natural astaxanthin is a high-value ketone carotenoid mainly derived from Haematococcus pluvialis, which is an excellent antioxidant for human consumption. To study the role of lipids in accumulation of astaxanthin, the H. pluvialis-derived astaxanthin synthesis pathway genes (ß-carotene ketolase gene, BKT and ß-carotene hydroxylase gene, BCH) and fatty acid elongation gene (mitochondrial trans-2-enoyl-coa reductase gene, MECR) were heterologously co-expressed in C. reinhardtii. Zeaxanthin, the precursor of astaxanthin synthesis, was significantly increased after BKT and BCH were expressed. In contrast, the α-carotene that competes with astaxanthin synthesis for lycopene decreased significantly. This redistribution of carbon flow was conducive to the synthesis of astaxanthin. In addition, the transformant only expressed astaxanthin metabolism related genes (BKT, BCH) would lead to an increase in total lipid, a decrease in monounsaturated fatty acids and an increase in polyunsaturated fatty acids. On this basis, the expression of MECR gene further increased the total lipid, and the relative content of different fatty acids also changed. The astaxanthin content of algal strains transformed with BKT and BCH genes was nearly 50% higher than that of the wild type. On this basis, the astaxanthin content of transformants expressing MECR gene related to long-chain fatty acid synthesis was increased by 227.5%. In this study, an astaxanthin production model similar to H. pluvialis by combining carotenoid metabolism and fatty acid metabolism was constructed in C. reinhardtii. The results suggest that the increase in astaxanthin is indeed linked to the regulation of fatty acid metabolism, and this link may involve the type of fatty acids and the dynamics of astaxanthin ester in cells. The strategy of promoting the synthesis of fatty acids has potential to achieve efficient production of astaxanthin in C. reinhardtii.

Symptom Patterning Across the Cancer Care Trajectory for Patients Receiving Chemoradiation for Head and Neck Cancer: A Retrospective Longitudinal Study Using Latent Transition Analysis.

BACKGROUND: Patients with head and neck cancer (HNC) experience a multitude of symptoms because of the tumor and its treatment. OBJECTIVE: To identify the symptom patterns present in cancer treatment and survivorship periods for patients with HNC using latent class analysis. METHODS: A retrospective longitudinal chart review was conducted to examine symptoms reported by patients who received concurrent chemoradiation for HNC in a regional Northeastern United States cancer institute. Latent class analysis was performed to identify the latent classes present across multiple timepoints during treatment and survivorship for the most commonly reported symptoms. RESULTS: In 275 patients with HNC, the latent transition analysis revealed 3 latent classes for both treatment and survivorship periods: (1) mild, (2) moderate, and (3) severe symptoms. Patients were more likely to report a greater number of symptoms in a more severe latent class. During treatment, moderate and severe classes had representation of all most common symptoms: pain, mucositis, taste alterations, xerostomia, dysphagia, and fatigue. Different symptom patterns emerged for survivorship, with prominence of taste alterations and xerostomia across all classes, and all symptoms present in the severe class. The probability of symptom expression varied more in the survivorship period compared with the treatment period. CONCLUSIONS: Patients reported numerous symptoms during active treatment persisting into survivorship. Patients tended to transition to more severe symptomatology as treatment progressed and to more moderate symptomatology as survivorship evolved. IMPLICATIONS FOR PRACTICE: Examining the trend of persistent moderate symptomatology into survivorship is useful to optimize symptom management.

The Impact of Early Life Experiences and Gut Microbiota on Neurobehavioral Development in Preterm Infants: A Longitudinal Cohort Study.

OBJECTIVES: The objective of this study is to investigate the impact of early life experiences and gut microbiota on neurobehavioral development in preterm infants during neonatal intensive care unit (NICU) hospitalization. METHODS: Preterm infants were followed from NICU admission until their 28th postnatal day or until discharge. Daily stool samples, painful/stressful experiences, feeding patterns, and other clinical and demographic data were collected. Gut microbiota was profiled using 16S rRNA sequencing, and operational taxonomic units (OTUs) were selected to predict the neurobehaviors. The neurobehavioral development was assessed by the Neonatal Neurobehavioral Scale (NNNS) at 36 to 38 weeks of post-menstrual age (PMA). Fifty-five infants who had NNNS measurements were included in the sparse log-contrast regression analysis. RESULTS: Preterm infants who experienced a high level of pain/stress during the NICU hospitalization had higher NNNS stress/abstinence scores. Eight operational taxonomic units (OTUs) were identified to be associated with NNNS subscales after controlling demographic and clinical features, feeding patterns, and painful/stressful experiences. These OTUs and taxa belonging to seven genera, i.e., Enterobacteriaceae_unclassified, Escherichia-Shigella, Incertae_Sedis, Veillonella, Enterococcus, Clostridium_sensu_stricto_1, and Streptococcus with five belonging to Firmicutes and two belonging to Proteobacteria phylum. The enriched abundance of Enterobacteriaceae_unclassified (OTU17) and Streptococcus (OTU28) were consistently associated with less optimal neurobehavioral outcomes. The other six OTUs were also associated with infant neurobehavioral responses depending on days at NICU stay. CONCLUSIONS: This study explored the dynamic impact of specific OTUs on neurobehavioral development in preterm infants after controlling for early life experiences, i.e., acute and chronic pain/stress and feeding in the NICU. The gut microbiota and acute pain/stressful experiences dynamically impact the neurobehavioral development in preterm infants during their NICU hospitalization.

Palliative care referral criteria and application in pediatric illness care: A scoping review.

BACKGROUND: Specialty pediatric palliative care services can help to address unmet care needs for children with complex and serious illness. Current guidelines support the identification of unmet palliative care needs; however, it is unknown how these guidelines or other clinical characteristics influence pediatric palliative care referral in research and practice. AIM: To evaluate the identification and application of palliative care referral criteria in pediatric illness care and research. DESIGN: A scoping review with a content analysis approach to summarize results. DATA SOURCES: Five electronic databases (PubMed, CINAHL, PsycINFO, SCOPUS, and Academic Search Premier) were used to identify peer-reviewed literature published in English between January 2010 and September 2021. RESULTS: We included 37 articles focused on the referral of pediatric patients to palliative care teams. The identified categories of referral criteria were: disease-related; symptom-related; treatment communication; psychosocial, emotional, and spiritual support; acute care needs; end-of-life care needs; care management needs; and self-referrals for pediatric palliative care services. We identified two validated instruments to facilitate palliative care referral and seven articles which described population-specific interventions to improve palliative care access. Nineteen articles implemented a retrospective health record review approach that consistently identified palliative care needs with varying rates of service use. CONCLUSIONS: The literature demonstrates inconsistent methods for identifying and referring children and adolescents with unmet palliative care needs. Prospective cohort studies and clinical trials would inform more consistent pediatric palliative care referral practices. More research is needed on palliative care referral and outcomes in community-focused pediatrics.

The other six OTUs were also associated with infant neurobehavioral responses depending on days at NICU stay. Conclusions: This study explored the dynamic impact of specific OTUs on neurobehavioral development among preterm infants after controlling for early life experiences, i.e., acute and chronic pain/stress, and feeding in the NICU.

COVID-19 is associated with bystander polyclonal autoreactive B cell activation as reflected by a broad autoantibody production, but none is linked to disease severity.

Coronavirus disease 2019 (COVID-19) is associated with autoimmune features and autoantibody production in a small subset of the population. Pre-existing neutralizing antitype I interferons (IFNs) autoantibodies are related to the severity of COVID-19. Plasma levels of IgG and IgM against 12 viral antigens and 103 self-antigens were evaluated using an antibody protein array in patients with severe/critical or mild/moderate COVID-19 disease and uninfected controls. Patients exhibited increased IgGs against Severe acute respiratory syndrome coronavirus-2 proteins compared to controls, but no difference was observed in the two patient groups. 78% autoreactive IgGs and 93% autoreactive IgMs were increased in patients versus controls. There was no difference in the plasma levels of anti-type I IFN autoantibodies or neutralizing anti-type I IFN activity of plasma samples from the two patient groups. Increased anti-type I IFN IgGs were correlated with higher lymphocyte accounts, suggesting a role of nonpathogenic autoantibodies. Notably, among the 115 antibodies tested, only plasma levels of IgGs against human coronavirus (HCOV)-229E and HCOV-NL63 spike proteins were associated with mild disease outcome. COVID-19 was associated with a bystander polyclonal autoreactive B cell activation, but none of the autoantibody levels were linked to disease severity. Long-term humoral immunity against HCOV-22E and HCOV-NL63 spike protein was associated with mild disease outcome. Understanding the mechanism of life-threatening COVID-19 is critical to reducing mortality and morbidity.

The association between psychological factors and self-care in patients with heart failure: an integrative review.

AIMS: This integrative review aims to describe the current evidence concerning the relationship between a broad range of psychological factors (depression, depressive symptoms, anxiety, stress, and type-D personality) and self-care in patients with heart failure. METHODS AND RESULTS: Six electronic databases were searched and keywords were used to identify potential eligible studies published within the last 10 years. To be eligible, individuals with heart failure aged 18 years or older and who were included in any type of observational study that examined the association between psychological factors and self-care were considered. Twenty articles were included, and 16 of them reported that depression/depressive symptoms were associated with poorer self-care, after controlling for age, sex, education level, cardiac history, or comorbidities. Five studies found that self-care confidence/self-efficacy mediates the relationship between depression/depressive symptoms and self-care. The association between depression/depressive symptoms and self-care varied in assessment methods and statistical approaches. Seven studies showed an inverse association between anxiety and self-care. Four studies found a stronger association between self-care and depression compared with the relationship between self-care and other psychological factors. Stress and type-D personality were both associated with self-care in four studies. CONCLUSION: Depression/depressive symptoms and anxiety were found to be inversely associated with self-care in patients with heart failure. Depression exhibited a stronger impact on self-care than other psychological factors. Limited studies assessed stress and type-D personality; the results should be considered with caution. Further studies are warranted on different psychological factors and their underlying mechanisms in individuals with heart failure.

Health disparities in preterm births.

Introduction: Black African American (B/AA) women have a 2-fold to 3-fold elevated risk compared with non-Hispanic White (W) women for preterm birth. Further, preterm birth is the leading cause of mortality among B/AA infants, and among survivors, preterm infant adverse health outcomes occur disproportionately in B/AA infants. Racial inequities in maternal and infant health continue to pose a public health crisis despite the discovery >100 years ago. The purpose of this study was to expand on reported preterm infant outcome disparities. A life-course approach, accumulation of lifelong stress, including discrimination, may explain social factors causing preterm birth rate and outcome inequities in B/AA mothers. Methods: Anthropometric measures and clinical treatment information for 197 consented participants were milled from electronic health records across 4 years. The Neonatal Infant Stressor Scale was used to tally acute and chronic painful/stressful procedures. Neurobehavioral differences were investigated using the Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale. Results: B/AA mothers gave birth to preterm infants earlier than W mothers. NICU hospitalization stays were extended more than 2 weeks for the significantly smaller B/AA preterm infants in comparison to the age-matched W preterm infants. A higher number of chronic lifesaving procedures with demonstrated altered stress response patterns were recorded for B/AA preterm infants. Discussion: This cross-sectional analysis of preterm birth rates and preterm infant developmental and neurodevelopmental outcomes are presented in the context of NICU stress and pain, with attendant implications for infant mortality and future health disparities. Preterm birth rate and outcome inequities further support the need to develop interventions and policies that will reduce the impact of discrimination and improve social determinants of health for Black, Indigenous, and other People of Color.

Nurses' experiences of caring for preterm infants in pain: A meta-ethnography.

Objective: Preterm infants are subjected to numerous painful procedures during their neonatal intensive care unit (NICU) hospitalization. Despite advancements in pain alleviation, nurses remain challenged to provide timely and effective pain management for preterm infants. Greater understanding of the lived experience of nurses caring for preterm infants in pain could provide novel insights to improve pain management for this vulnerable population. The aim of this meta-ethnography was to synthesize and interpret qualitative findings of nurses' experiences of taking care of preterm infants in pain. Methods: An extensive literature search in PubMed, CINAHL, PsycINFO, Scopus, BIOSIS and ProQuest Dissertation and Theses Database was conducted, including studies within the past 10 years. Two nursing researchers conducted data extraction and analysis independently. Inclusion criteria were applied to search for qualitative studies of nurse participants who worked in the NICU taking care of preterm infants. Studies published in a language other than English, articles that did not include qualitative data and qualitative data that could not be extracted from the findings or did not discuss nurses' experiences were excluded. Critical Appraisal Skills Programme was used for literature quality evaluation. Results: Eight studies remained after further screening according to inclusion and exclusion criteria. These eight studies were conducted from 2013 to 2018 and totally enrolled 205 nurses from Iran, Canada, the United States, Finland, Sweden, Switzerland, and Australia. Five themes emerged on the nurses' perspectives of taking care of preterm infants in pain: 1) They sense the neonatal pain; 2) Adverse consequences of unrelieved pain; 3) Barriers of managing pain; 4) Concerns of available approaches for pain relief; 5) Failure to work with parents. Conclusions: This meta-ethnography identified nurses' understanding of pain in preterm infants that can be assessed, and they acknowledged that unrelieved pain could cause developmental deficits in infants. The barriers are lack of training and support on pain assessment and intervention in preterm infants. Optimizing workload and environment, developing age-specified pain assessment and intervention, receiving emotional support and training, and building up a rapport with parents are urgent needs for nurses to provide better care to infants having pain.

COVID-19 mRNA vaccine BNT162b2 induces autoantibodies against type I interferons in a healthy woman.

Coronavirus disease (COVID-19) caused by SARS-CoV-2 virus is associated with a wide range of clinical manifestations, including autoimmune features and autoantibody production in a small subset of patients. Pre-exiting neutralizing autoantibodies against type I interferons (IFNs) are associated with COVID-19 disease severity. In this case report, plasma levels of IgG against type I interferons (IFNs) were increased specifically among the 103 autoantibodies tested following the second shot of COVID-19 vaccine BNT162b2 compared to pre-vaccination and further increased following the third shot of BNT162b2 in a healthy woman. Unlike COVID-19 mediated autoimmune responses, vaccination in this healthy woman did not induce autoantibodies against autoantigens associated with autoimmune diseases. Importantly, IFN-α-2a-induced STAT1 responses in human PBMCs in vitro were suppressed by adding plasma samples from the study subject post- but not pre-vaccination. After the second dose of vaccine, the study subject exhibited severe dermatitis for about six months and responded to treatments with Betamethasone Dipropionate Ointment and antihistamines for about one month. Immune responses to type I IFN can be double-edged swords in enhancing vaccine efficacy and immune responses to infectious diseases, as well as accelerating chronic disease pathogenesis (e.g., chronic viral infections and autoimmune diseases). This case highlights the BNT162b2-induced neutralizing anti-type I IFN autoantibody production, which may affect immune functions in a small subset of general population and patients with some chronic diseases.

Associations of Mitochondrial Function, Stress, and Neurodevelopmental Outcomes in Early Life: A Systematic Review.

Early life stress is commonly experienced by infants, especially preterm infants, and may impact their neurodevelopmental outcomes in their early and later lives. Mitochondrial function/dysfunction may play an important role underlying the linkage of prenatal and postnatal stress and neurodevelopmental outcomes in infants. This review aimed to provide insights on the relationship between early life stress and neurodevelopment and the mechanisms of mitochondrial function/dysfunction that contribute to the neuropathology of stress. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to develop this systematic review. PubMed, Scopus, PsycINFO, and Biosis databases were searched for primary research articles published between 2010 and 2021 that examined the relationships among mitochondrial function/dysfunction, infant stress, and neurodevelopment. Thirty studies were identified. There is evidence to support that mitochondrial function/dysfunction mediates the relationship between prenatal and postnatal stress and neurodevelopmental outcomes in infants. Maternal transgenerational transmission of mitochondrial bioenergetic patterns influenced prenatal stress induced neurodevelopmental outcomes and behavioral changes in infants. Multiple functionally relevant mitochondrial proteins, genes, and polymorphisms were associated with stress exposure. This is the first review of the role that mitochondrial function/dysfunction plays in the association between stress and neurodevelopmental outcomes in full-term and preterm infants. Although multiple limitations were found based on the lack of data on the influence of biological sex, and due to invasive sampling, and lack of longitudinal data, many genes and proteins associated with mitochondrial function/dysfunction were found to influence neurodevelopmental outcomes in the early life of infants.

Somatosensory Profiles Differentiate Pain and Psychophysiological Symptoms Among Young Adults With Irritable Bowel Syndrome: A Cluster Analysis.

OBJECTIVE: The aim of this study was to investigate if somatosensory profiles can differentiate pain and psychophysiological symptoms among young adults with irritable bowel syndrome (IBS). METHODS: We performed a cluster analysis of data collected from a randomized clinical trial of 80 IBS patients and 21 age-matched healthy controls (HCs) to stratify pain and symptoms among young adults with IBS by their peripheral sensory profiles. Data of quantitative sensory testing and IBS-related pain and symptoms were collected at baseline and 6-week and 12-week follow-ups. RESULTS: Using the K-means method, IBS patients were classified into 2 clusters, the "IBS normal threshold" (IBS-NT) and the "IBS increased threshold" (IBS-IT). The IBS-NT cluster had a similar pain threshold as the HCs, and the IBS-IT cluster had an increased threshold of somatic pain perception (lower cold pain threshold, higher heat pain threshold, and higher pressure pain threshold, all P<0.001) than HCs. Compared with the IBS-NT cluster, the IBS-IT cluster reported higher levels of IBS-related pain intensity, anxiety, fatigue, and sleep disturbance over the 3 visits (all P<0.05). DISCUSSION: Young adults with IBS fell into 2 clusters, one with a similar sensory threshold as the HCs and another with an increased pain threshold, who reported higher pain intensity and more severe symptoms. Somatic sensory profiles should be integrated into further personalized self-management intervention among patients with IBS.
