Abstract

Background: Gene expression is regulated by transcription factors, cofactors, and epigenetic mechanisms. Coexpressed genes indicate similar functional categories and gene networks. Detecting gene-gene coexpression is important for understanding the underlying mechanisms of cellular function and human diseases. A common practice of identifying coexpressed genes is to test the correlation of expression in a set of genes. In single-cell RNA-seq data, an important challenge is the abundance of zero values, so-called “dropout”, which results in biased estimation of gene-gene correlations for downstream analyses. In recent years, efforts have been made to recover coexpressed genes in scRNA-seq data. Here, our goal is to detect coexpressed gene pairs to reduce the “dropout” effect in scRNA-seq data using a novel graph-based k-partitioning method by merging transcriptomically similar cells. Results: We observed that the number of zero values was reduced among the merged transcriptomically similar cell clusters. Motivated by this observation, we leveraged a graph-based algorithm and develop an R package, scCorr, to recover the missing gene-gene correlation in scRNA-seq data that enables the reliable acquisition of cluster-based gene-gene correlations in three independent scRNA-seq datasets. The graphically partitioned cell clusters did not change the local cell community. For example, in scRNA-seq data from peripheral blood mononuclear cells (PBMCs), the gene-gene correlation estimated by scCorr outperformed the correlation estimated by the nonclustering method. Among 85 correlated gene pairs in a set of 100 clusters, scCorr detected 71 gene pairs, while the nonclustering method detected only 4 pairs of a dataset from PBMCs. The performance of scCorr was comparable to those of three previously published methods. As an example of downstream analysis using scCorr, we show that scCorr accurately identified a known cell type (i.e., CD4+ T cells) in PBMCs with a receiver operating characteristic area under the curve of 0.96. Conclusions: Our results demonstrate that scCorr is a robust and reliable graph-based method for identifying correlated gene pairs, which is fundamental to network construction, gene-gene interaction, and cellular omic analyses. scCorr can be quickly and easily implemented to minimize zero values in scRNA-seq analysis and is freely available at https://github.com/CBIIT-CGBB/scCorr.

Abstract

Background Diagnosed between ages 20 and 39 years, young adult (YA) cancer survivors have faced disruption to their lives well before the COVID-19 pandemic. Often seen as an at-risk population within cancer survivors, YAs experience the demands of a serious illness, such as cancer, alongside meeting the typical milestones of young adulthood and often have worse quality of life than their noncancer peers. There is a need to further study the effect of the COVID-19 pandemic on specific populations, including YA cancer survivors (YACS), as it relates to work. Objectives The aim of this study was to explore working YACS' experiences during the COVID-19 pandemic and identify facets of cancer survivorship that researchers can use to explore COVID-19 survivorship further. Methods Secondary thematic analysis of 40 semistructured, qualitative interviews conducted through Zoom audio during the COVID-19 pandemic. YA hematologic cancer survivors were recruited through social media; they were eligible if they had completed active therapy, were within 5 years of their diagnosis, and working at the time of diagnosis. Interviews were transcribed verbatim and subjected to thematic content analysis. Results Themes surrounded COVID-19's influence on working YACS' experiences, with the overarching theme: "From solo to shared experience: A change in awareness and understanding."A subtheme was "Lesson reaffirmed: Reimagining the work environment."Discussion The consequences of COVID-19 on the overall quality of life for YACS are multilevel. Establishing the evidence for effective interventions to support YACS in the workplace, whether physical or virtual, is critically needed. Research is needed on YACS' risk and resilience factors that could ultimately impact future health and quality of life.

Abstract

Americans near the end of life experience high rates of nonbeneficial, burdensome, and preventable hospital-based care. If patients' goals of care are unknown or unclear, they have higher rates of hospitalization at the end of life. The demand for palliative care has grown exponentially because of its impact on quality of life, symptom burden, and resource use, requiring the development of new palliative care models. Nurses' holistic outlook and patient-centered focus make them ideal to deliver telephonic palliative care. This article discusses 4 cases delivered by a nurse-led telephonic palliative care program, a part of the Emergency Medicine Palliative Care Access project, which is a randomized controlled trial comparing outpatient palliative care with nurse-led telephonic case management after an emergency department visit. Telephonic nurses discuss patients' goals, fears, hopes, and concerns regarding their illness and its trajectory that inform decisions for future interventions and treatments. In addition, they share this information with the patients' surrogate decision-makers and clinicians to facilitate care coordination and symptom management. For seriously ill patients, nurses' abilities and expertise, as well as the difficulties of providing care through in-person models of palliative care delivery, make a nurse-led telephonic model an optimal option.

Abstract

Background Nursing care is essential to overall quality of healthcare experienced by patients and families - especially during childbearing. However, evidence regarding quality of nursing care during labor and birth is lacking, and established nurse-sensitive outcome indicators have limited applicability to maternity care. Nurse-sensitive outcomes need to be established for maternity care, and prior research suggests that the initiation of human milk feeding during childbirth hospitalization is a potentially nurse-sensitive outcome. Objective The aim of this study was to determine the relationship between nurse-reported staffing, missed nursing care during labor and birth, and exclusive breast milk feeding during childbirth hospitalization as a nurse-sensitive outcome. Methods 2018 Joint Commission PC-05 Exclusive Breast Milk Feeding rates were linked to survey data from labor nurses who worked in a selected sample of hospitals with both PC-05 data and valid 2018 American Hospital Association Annual Survey data. Nurse-reported staffing was measured as the perceived compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines by the labor and delivery unit. Data from the nurse survey were aggregated to the hospital level. Bivariate linear regression was used to determine associations between nurse and hospital characteristics and exclusive breast milk feeding rates. Generalized structural equation modeling was used to model relationships between nurse-reported staffing, nurse-reported missed care, and exclusive breast milk feeding at the hospital level. Results The sample included 184 hospitals in 29 states and 2,691 labor nurses who worked day, night, or evening shifts. Bivariate analyses demonstrated a positive association between nurse-reported staffing and exclusive breast milk feeding and a negative association between missed nursing care and exclusive breast milk feeding. In structural equation models controlling for covariates, missed skin-to-skin mother-baby care and missed breastfeeding within 1 hour of birth mediated the relationship between nurse-reported staffing and exclusive breast milk feeding rates. Discussion This study provides evidence that hospitals' nurse-reported compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines predicts hospital-exclusive breast milk feeding rates and that the rates are a nurse-sensitive outcome.

Abstract

Background. Quality patient care requires collaboration among health professionals. In 2016, 250,000 U.S. citizens died from preventable medical errors. One individual does not cause such errors. Researchers cite a lack of nurse–physician collaboration (NPC) as a contributing factor. Method. Streubert’s phenomeno-logical design guided this study. A rigorous analysis of eight nurse interviews was conducted and reached data saturation. Results. A developed formalized “ex-haustive description” of nurses’ lived experiences with NPC was validated by all nurse participants. One new finding was that nurses had difficulty initiating NPC for their patients early in their career and this remained an issue at times. Conclusion. This is the first U.S. qualitative study in which nurses described their positive and negative experiences with NPC and their desire to improve NPC for enhanced patient outcomes. Implications for nurse educator specialists, hospital adminis-trators, and researchers were derived.

Abstract

Chinese immigrants in the US are disproportionately affected by gestational diabetes mellitus (GDM) and type 2 diabetes (T2D). The aims of this study were to describe their physical activity (PA) and sedentary behaviors (SB) patterns and to identify determinates of objectively-measured PA and SB among Chinese immigrants in the US with prior GDM. We conducted a cross-sectional study among 106 Chinese immigrants with prior GDM across the US. PA and SB were measured by GT9X+ hip accelerometers for 7 consecutive days. Validated questionnaires in English and Chinese were used to assess knowledge and risk perceptions as well as cultural and psychosocial characteristics. Descriptive, bivariate, and multiple regression analyses were performed. Only 27% of participants met the PA guidelines. The median duration of moderate–vigorous-intensity PA (MVPA) per week was 79 (IQR 38–151) minutes. Participants had an average of 9.2 ± 1.4 h of sedentary time per day. Living with parents (who may provide family support) was associated with more MVPA minutes per week, more steps per day, and a greater likelihood of meeting PA guidelines. Higher levels of acculturative stress were associated with fewer MVPA minutes per week. Being employed and having a lower BMI were associated with more SB. Strategies are needed to increase MVPA among this high-risk group, including decreasing acculturative stress and increasing family support. Different strategies are needed to decrease SB among this population.

Abstract

Objective: Despite recent research focused on aging well, little is known regarding the goals and expectations from long-term services and supports (LTSS) use among older adults. Methods: To address this knowledge gap, interviewer-guided surveys with older adults newly receiving LTSS in home and community-based, assisted living, and nursing home settings in Philadelphia, New Jersey, and New York were conducted. Results: Twelve subthemes regarding the goals and expectations of 464 older adults receiving LTSS and in the context of Aging Well emerged from our analysis: maintaining function, optimizing health and circumstances, maintaining the status quo, transitioning back to the previous state, achieving independence, preserving cognitive function and capacity for psychosocial and emotional health, achieving purpose, increasing quality of life, receiving social support, increasing engagement, relieving burden, and feeling a sense of security/safety. Discussion: This in-depth analysis of qualitative data provides context for LTSS use among older adults.

Abstract

Opioid overdose continues to affect thousands each year in the United States, with nearly 850,000 lives lost within the last 20 years. It will take a comprehensive and coordinated approach from all members of the health care team and health care institutions, in addition to governmental officials, public safety, and community organizations to mitigate this crisis. Nurses can be instrumental in educating patients, families, and community members about ways to combat this epidemic, instrumental in advocating for their patients, advocating for reform, as well as continuing to bring awareness to this health crisis and provoke dialogue about ongoing solutions to end it.

Abstract

Background: The coronavirus disease 2019 (COVID-19) pandemic has highlighted the importance of understanding the underlying conditions that lead to COVID-19. Oral health has systemic implications in the maintenance of a healthy state. This study aimed to summarize evidence on the prevalence of oral health conditions in participants with COVID-19 and assess the associations between oral health conditions and COVID-19 related outcomes.Methods: Article searches were conducted in five databases and the gray literature from December 1, 2019 to March 1, 2021. Studies that reported oral health conditions for participants with COVID-19 and/or examined associations between oral health and COVID-19 were included.Results: We identified 15 articles that encompassed 5,377 participants with COVID-19 from 10 countries. Dry mouth was the most common oral health condition reported (41.0%), followed by oral lesions (38.8%), orofacial pain (18.3%), and periodontal symptoms (11.7%). Based on the pooled odds ratios (ORs), periodontal symptoms were not associated with COVID-19 positivity (OR = 1.1; 95% confidence intervals [CI], 0.73-1.65) or mortality (OR = 2.71; 95% CI, 0.64-11.51), but were associated with COVID-19 severity (OR = 3.18; 95% CI, 1.81-5.58).Conclusions: Oral health conditions are common in participants with COVID-19 and should be considered in both the onset and progression of this disease. Knowledge in this area is still limited, and the quality of the data extracted was low. Further longitudinal studies are needed to ascertain whether oral health conditions are a consequence of infection with SARS-CoV-2 or whether they predate infection and are risk factors for COVID-19.

Abstract

Introduction: The aim of this research was to assess the association between inflammation and oral health and diabetes, as well as the mediating role of oral hygiene practice in this association. Methods: Data were from the 2009–2010 National Health and Nutrition Examination Survey. The analytical sample consisted of 2,191 respondents aged 50 and older. Poor oral health was clinically defined by significant tooth loss (STL) and periodontal disease (PD). Diabetes mellitus (DM) was determined by glycemic levels. The outcome variable was serum C-reactive protein (CRP) level, dichotomised as ≥1 mg/dL (elevated CRP) vs <1 mg/dL (not elevated CRP). Two path models, one using STL and DM as the independent variable, the other using PD and DM as the independent variable, were estimated to assess the direct effects of having poor oral health and DM on elevated CRP and the mediating effects of dental flossing. Results: In path model 1, individuals having both STL and DM (adjusted odds ratio [AOR], 1.92; 95% confidence interval [CI], 1.30–2.82) or having STL alone (AOR, 2.30; 95% CI, 1.68–3.15) were more likely to have elevated CRP than those with neither STL nor DM; dental flossing (AOR, 0.92, 95% CI, 0.88–0.96) was associated with lower risk of elevated CRP. In path model 2, no significant association was found between having both PD and DM and elevated CRP; dental flossing (AOR, 0.91; 95% CI:, 0.86–0.94) was associated with lower risk of elevated CRP. Conclusions: Findings from this study highlight the importance of improving oral health and oral hygiene practice to mitigate inflammation. Further research is needed to assess the longer-term effects of reducing inflammation.

Abstract

Purpose:RNs have served as the bedrock of the response to the COVID-19 pandemic, working under unprecedented and difficult conditions. In this study, we sought to understand the experiences of nurses working across a range of care settings in the United States during the first six months of the pandemic, and to learn more about barriers to and facilitators of their work.Methods:This is a qualitative descriptive study. We recruited participants online through regional professional nursing membership listservs, program directors of occupational health nursing training programs, and social media. After completing a survey, potential participants were invited to complete an individual semistructured interview via the Zoom platform. From June through August 2020, we conducted 34 interviews. Content analysis was performed using ATLAS.ti software.Results:The overarching theme - "Losing the art and failing the science of nursing" - underscored the barriers nurses faced in the early months of this pandemic. It reflected the deeply painful disruptions in the care nurses were accustomed to providing their patients. Themes that reflected barriers included disrupted nurse-patient connection, lack of personal protective equipment and fear of infection, lack of evidence-based guidance, and understaffing, all of which drastically altered the delivery of nursing care. Themes that reflected facilitators to nurses' work included camaraderie and strength and resourcefulness.Conclusions:The study findings give important direction to nurse leaders, researchers, and organizations concerning potential areas of support that nurses need during and after this pandemic. Future research should investigate the long-term impact of COVID-19 and similar public health crises on nurses, as well as interventions that could support the workforce after an extended crisis.

Abstract

Objective: To examine the prevalence of orofacial pain and associated factors in Chinese older adults at the end of life. Methods: This cross-sectional study included 1646 participants (65 years or older) in their last year of life from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We used the 6-month prevalence questions to measure two specific orofacial pain symptoms: toothache, and jaw or facial pain. Logistic regression analyses were used to examine factors, such as socioeconomic status, health behaviours and chronic diseases, that were associated with these two orofacial pain symptoms in the last year of life. Results: The 6-month prevalence estimates for toothache and jaw pain or facial pain for older adults in the last year of life were 14.1% and 4.5% respectively. Higher socioeconomic status was associated with lower odds of toothache and jaw pain or facial pain. Smoking was associated with high odds of toothache. Participants who brushed their teeth at least once a day were more likely to have toothache and jaw or facial pain than those who did not. Having any chronic conditions was associated with higher odds of toothache and jaw or facial pain. Older adults who had at least one tooth were more likely to have jaw or facial pain than those without any teeth. Conclusion: A considerable proportion of Chinese older adults in their last year of life reported toothache and/or jaw pain or facial pain. These findings suggest that appropriate measures need to be taken to address the oral health needs in these vulnerable individuals, especially those of low socioeconomic status and chronic conditions.

Abstract

The COVID-19 pandemic and public health response of the US health care system and government provided unique opportunities for nursing education as it disrupted the usual mode of operation. An honors program at a private university at the epicenter of the pandemic pivoted multiple times to avoid failing to support the capstone projects of its inaugural cohort. Collaborative outreach with mentors and instructional technologists created opportunities for virtual delivery of patient and nursing student education and program evaluation. The lessons learned became part of the roster of resources for future cohorts to sustainably design and deliver their capstone projects.

Abstract

Using survey data collected from January to September 2018 (N = 430), this study examined how neighborhood physical conditions and social cohesion were associated with psychological well-being via pathway of self-management abilities among Chinese older adults living in Honolulu, Hawai’i. Results showed that, for the whole sample, neighborhood physical conditions and social cohesion were significantly associated with psychological well-being, and the main associations were mediated by self-management abilities in the amount of 34% and 60%, respectively. Similar results were found for the foreign-born, whereas for the U.S.-born, psychological well-being was significantly related to neighborhood physical conditions only. Our findings reveal the importance of neighborhood conditions and individual psychological resources on psychological well-being of Chinese older adults.

Abstract

This study examined the mediator role of social capital on the association between perceived neighborhood environment and life satisfaction among older adults in urban China, and further tested the moderating effect of gender in the above paths (i.e., from neighborhood environment to life satisfaction; from neighborhood environment to social capital; from social capital to life satisfaction). We used quota sampling approach to recruit 472 respondents aged 60 years old or older in Shanghai in 2020. From the perspective of structural equation modeling, multiple group analysis was conducted to examine the proposed hypotheses. The measurement model of social capital was well established in urban Chinese community contexts. Based on the whole sample, the results of the mediation model showed that social capital played a mediation role in the association between neighborhood environment and life satisfaction. Furthermore, the results of multiple group analysis showed that the association between neighborhood environment and cognitive social capital was only significant among older women. The findings highlight the role of neighborhood environment and social capital in building age-friendly communities.

Abstract

Refining existing dietary assessment methods to reduce measurement error and facilitate the routine evaluation of dietary quality is essential to inform health policy. Notable advancements in technology in the past decade have enhanced the precision and transformation of dietary assessment methods with applications toward both population health and precision nutrition. Within population health, innovative applications of big data including use of automatically collected food purchasing data, quantitative measurement of food environments, and novel, yet simplified dietary quality metrics provide important complementary data to traditional self-report methods. Precision nutrition is similarly advancing with greater use of validated biomarkers for assessing dietary patterns and understanding individual variability in metabolism. Concurrently enhancing our understanding of diet-disease relations at the population health and precision nutrition levels provides tremendous potential to generate evidence needed to advance public health nutrition policy. This commentary highlights the importance of these advances toward progressing the field of dietary assessment and discusses the application of food purchasing data, data analytics, alternative dietary quality metrics, and -omics technology in population and clinical medicine.

Abstract

OBJECTIVES: To describe symptoms of malignant pleural mesothelioma (MPM), a rare cancer associated with a poor prognosis and significant symptoms, via a pilot mixed-methods study, because it is unclear whether MPM symptom assessment tools accurately characterize these symptoms. SAMPLE & SETTING: Participants with MPM were recruited from a large northeastern U.S. academic medical center with an interprofessional MPM program. METHODS & VARIABLES: A mixed-methods pilot approach was employed using the Lung Cancer Symptom Scale for Mesothelioma (LCSS-Meso) to quantitatively describe MPM symptoms and semistructured interviews to qualitatively capture these symptoms. RESULTS: Seven participants with MPM completed the LCSS-Meso and qualitative interviews. The five symptoms evaluated by the LCSS-Meso were confirmed as symptoms of MPM in participant interviews. However, the presence and severity of some symptoms were either under-or overestimated by the scale. Two additional symptoms, distress and sleep disturbance, also emerged from the qualitative interviews. IMPLICATIONS FOR NURSING: Nurses caring for people with MPM should have a thorough understanding of common symptoms, but they must also explore additional symptoms that are meaningful to each patient.

Abstract

Introduction: Well-being and turnover intent represent key aspects to the promotion of a healthy workforce. Alarming levels of burnout and low levels of well-being have been documented in health professionals across care settings. Not only do high levels of burnout, low well-being and high turnover affect health professionals, but they are associated with poor patient care. However, limited research has investigated this topic specifically in hospice interdisciplinary team (IDT) members, nurses, chaplains, social workers. Thus, the purpose of this study was to explore hospice IDT members’ well-being, and turnover intent. Methods: This observational, pilot study used quantitative surveys to examine the well-being, and turnover intention at baseline and at 3 months. Twenty-five hospice IDT members at one site participated. Results: Paired t-tests and percent change demonstrated significant decreases in compassion satisfaction (44.5 vs. 42.1, p = 0.04) and secondary traumatic stress score (18.5 vs. 13.3, p = 0.0001) and a significant increase in burnout score (17.6 vs. 20.5, p = 0.03) from baseline to follow up. Employee turnover slightly decreased from baseline to follow-up. Conclusions: In this pilot study, hospice IDT members had low levels of well-being at baseline that worsened over 3-months indicating a higher potential risk for burnout. Moreover, given the COVID-19 pandemic, this may be an ominous sign of what lies ahead for hospice providers regarding turnover, leading to significant long-term staffing problems in the field. If these results hold true in a larger sample, it could necessitate developing and testing further strategies to ensure a healthy and stable workforce.
