Designathons in health research: a global systematic review

INTRODUCTION

A designathon is a three-stage participatory activity informed by design thinking. There is a growing literature on designathons in health. This study synthesised designathons' effectiveness and implementation-related factors to address health challenges.

METHODS

We searched Cochrane Library, Embase, PubMed, Scopus and the ClinicalTrials.gov registry for articles containing primary data on designathons for health from their dates of inception to 29 November 2022. We retrieved additional studies from citation searching and a complementary open call. We synthesised data on designathons' effectiveness (ie, engagement, outputs and implementation), required resources and implementation-related factors (ie, resources, facilitators, barriers, strengths and limitations). We assessed the risk of bias using a checklist adapted from Joanna Briggs Institute Critical Appraisal tools.

RESULTS

In total, 4973 citations were identified, and 42 studies were included. In total, 26 studies (62%) were from high-income countries. The median number of total participants was 49, divided into a median of 8 teams. The duration of the intensive collaboration phase ranged from 3 hours to 7 days. Common evaluation criteria were feasibility, innovation and impact. Idea and prototype outputs included mobile phone applications, educational programmes and medical devices. Interventions developed from a designathon was estimated to be highly cost-effective. The most common facilitators were interdisciplinary participants and high-quality mentorship. The most common barriers were suboptimal execution of the events, difficulties in balancing interdisciplinary participants across teams and limited support for participants along the process. There were limited data on required resources and further implementation of solutions after designathons.

CONCLUSION

Given designathons' adaptability in terms of budget, mode of delivery, type of output and involvement of diverse participants, including end users, designathons can be implemented in a wide range of contexts to address various health issues.

Cognitive Function in Adults With Acute Myeloid Leukemia Treated With Chemotherapy: A Systematic Review

BACKGROUND

Chemotherapy is essential for treating acute myeloid leukemia (AML). Previous studies concluded that survivors of cancer who were treated with chemotherapy experience cognitive impairment. Therefore, it is important to understand cognitive function in survivors of AML.

OBJECTIVE

The aim of this study was to explore distributions and correlates of cognitive function, and prediction of cognitive function on other outcomes in adults with AML who were treated with chemotherapy.

METHODS

A health science librarian systematically searched PubMed, CINAHL, PsycINFO, and EMBASE databases. Two reviewers independently conducted the title, abstract, and full-text screening. Data were extracted and synthesized based on the aims of the review.

RESULTS

A total of 10 articles were included. Findings indicate that up to 62.2% of adults with AML experienced impaired cognitive function after starting chemotherapy. Three studies found cognitive function remained stable over time. Education and cytokines were potential correlates of cognitive function. Worse cognitive function may predict lower physical performance and higher mortality, although the results were inconsistent across studies.

CONCLUSION

Impaired cognitive function was observed in adults with AML who were treated with chemotherapy. However, no study used a validated subjective cognitive-function-specific patient-reported questionnaire, and previous studies focusing on cognitive function included relatively young samples. Hence, further research on cognitive function in older adults with AML is needed.

IMPLICATIONS FOR PRACTICE

Because of the high prevalence of cognitive impairment identified, it is important to screen cognitive function in adults with AML who are planning to receive chemotherapy to intervene and provide support earlier.

Prevalence of persistent hypertension following pregnancy complicated by hypertensive disorders in low- and middle-income countries: a systematic review

Background

Hypertensive disorders of pregnancy can lead to persistent hypertension (pHTN) in the months and even years following delivery. However, its prevalence in low- and middle-income countries (LMICs) is not well characterized.

Objective

To synthesize available evidence on the pHTN prevalence following a pregnancy complicated by hypertensive disorders of pregnancy in LMICs.

Search strategy

PubMed, CINAHL Plus, Global Health (EBSCOhost), and Scopus from inception through a search date of July 12, 2022, and updated on January 2, 2024.

Selection criteria

Cross-sectional studies and cohort studies reporting pHTN prevalence were eligible.

Data collection and analysis

We conducted a narrative synthesis of data and categorized reported prevalence time points into several broader categories. We used the Newcastle-Ottawa checklist to assess the risk of bias. The protocol is registered in PROSPERO (CRD42022345739).

Results

We reviewed 1,584 abstracts and identified 22 studies that reported pHTN between 2000 and 2023 from 14 LMICs. The overall prevalence of pHTN ranged between 6.9% and 62.2%, with the highest prevalence noted within African studies and the lowest in South American studies. Estimates at different follow-up periods postpartum were 6.9%-42.9% at six weeks, 34.0%-62.2% at three months, 14.8%-62.2% at six months, 12.7%-61.2% at 12 months, and 7.5%-31.8% at more than 12 months. The quality score of the selected studies ranged from 50% to 100%.

Conclusions

The extant literature reports a high prevalence of pHTN in LMICs following a pregnancy complicated by hypertensive disorders. To reduce long-term complications of pHTN, programs should emphasize early screening and linkages to long-term care for at-risk women.

Early Infant Feeding Practices among Women Engaged in Paid Work in Africa: A Systematic Scoping Review

Around the world, paid work without appropriate structural support is a key barrier to optimal breastfeeding practices. To better protect, promote, and support optimal breastfeeding practices among working women in Africa, this scoping review sought to understand how paid work influences infant feeding practices in the first 6 mo of life and what support women need to manage work and optimal infant feeding practices. We systematically searched PubMed, Scopus, Global Health, and CINAHL Plus, screened 2436 abstracts, and reviewed 322 full-text articles using Covidence for review and charting. We identified 203 articles that met the inclusion criteria. We identified 32 quantitative, 10 qualitative, 3 mixed-methods, and 2 review articles that focused on examining the relationship between work and breastfeeding, and 109 quantitative, 22 qualitative, 21 mixed-methods, and 4 review articles that included work as part of broader breastfeeding research but did not focus on work. Most studies reported a significant negative association between work and exclusive breastfeeding. Three major domains were reported in the qualitative studies: challenges to managing work and infant feeding, receiving support from employers and family members/caregivers, and strategies for feeding infants when the mother is working. Reviewed studies proposed recommendations to increase support for breastfeeding through changes to policies and support within worksites, the health system, and childcare; however, evidence of previously implemented policies or programs is limited. We recommend more consistent definitions and measurement of women's work. Future research is needed on the impact of implementing various strategies and benefits for breastfeeding at workplaces, as well as efforts to support breastfeeding among informal workers.

Scoping review of values elicitation tools for treatment decisions in hepatocellular carcinoma

BACKGROUND

Treatment choices in hepatocellular carcinoma (HCC) involve consideration of tradeoffs between the benefits, toxicities, inconvenience, and costs. Stated preference elicitation methods have been used in the medical field to help evaluate complex treatment decision-making. The aim of this study was to conduct a scoping review to assess the evidence base for the use of preference elicitation tools or willingness to pay/willingness to accept methods for HCC treatment decision-making from both the patient and provider perspective.

METHODS

We performed a scoping review to identify abstracts or manuscripts focused on the role preference elicitation tools or willingness to pay/willingness to accept methods for HCC treatment options among patients, caregivers, and/or providers. Two researchers independently screened full-text references and resolved conflicts through discussion. We summarized key findings, including the type and setting of preference-elicitation tools used for HCC treatment decisions.

RESULTS

Ten published abstracts or manuscripts evaluated the role of preference elicitation tools for HCC treatments. The studies revealed several attributes that are considered by patients and providers making HCC treatment decisions. Many of the studies reviewed suggested that while patients place the most value on extending their overall survival, they are willing to forgo overall survival to avoid risks of treatments and maintain quality of life. Studies of physicians and surgeons found that provider preferences are dependent on patient characteristics, provider specialty, and surgeon or hospital-related factors.

CONCLUSION

This scoping review explored both patient and physician preferences towards treatment modalities in all stages of HCC. The studies revealed a large scope of potential attributes that may be important to patients and that many patients are willing to forgo survival to maintain quality of life. Further research should explore both preference elicitation of currently available and emerging therapies for HCC as well as the use of this data to develop patient-facing tools to assist in navigating treatment options.

Toddler milk: a scoping review of research on consumption, perceptions, and marketing practices

Toddler milk is an ultra-processed beverage consisting primarily of powdered milk, caloric sweeteners, and vegetable oil. Pediatric health authorities do not support the use of toddler milk, and emerging evidence suggests that toddler-milk marketing practices may mislead consumers. However, studies have not synthesized the extent of toddler-milk marketing practices or how these practices affect parents' decisions about whether to serve toddler milk. We aimed to summarize the literature about toddler milk to identify what is known about: (1) parents' toddler-milk purchasing and feeding behaviors, (2) toddler-milk marketing, and (3) how marketing practices influence parents' beliefs and perceptions about toddler milk. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR), we systematically searched 8 databases (PubMed, APA PsycINFO, Scopus, Cochrane Central, Embase, CINAHL, Communication & Mass Media Complete, and Business Source Premier). We identified 45 articles about toddler milk. Studies were conducted in 25 countries across 6 continents. Five types of findings emerged: (1) consumption and feeding behaviors, (2) demographic correlates of toddler-milk purchasing and consumption, (3) misperceptions and beliefs, (4) increased sales, and (5) increased marketing and responses to marketing. The included articles suggested that toddler-milk sales are growing rapidly worldwide. Findings also revealed that toddler-milk packages (eg, labels, branding) resemble infant formula packages and that toddler-milk marketing practices may indirectly advertise infant formula. Purchasing, serving, and consumption of toddler milk were higher in Black and Hispanic populations than in non-Hispanic White populations, and parents with higher educational attainment and income were more likely to offer toddler milk to their children. Findings suggest a need for policies to prevent cross-marketing of toddler milk and infant formula, reduce provision of toddler milk to infants and toddlers, and prevent caregivers from being misled about toddler-milk healthfulness.

Physical Activity Intervention Characteristics and Effects on Behavioral and Health-Related Outcomes Among Adolescents and Young Adults Living with and Beyond Cancer: A Systematic Review

Participation in physical activity (PA) during and after cancer treatment is safe and beneficial in the adolescent and young adult (AYA) cancer population. PA can positively impact health-related outcomes; however, participation remains low. This systematic review aims to describe PA intervention characteristics and outcomes in AYA survivors of cancer (AYASCa). This review followed Preferred Reporting Index for Systematic Reviews and Meta Analyses (PRISMA) guidelines and was registered with Prospero (CRD42022365661). PubMed, CINAHL, and Scopus databases were searched for randomized control trials (RCTs) and pre/post-test studies without a control group through December 31, 2022. Data included: participant demographics, PA intervention characteristics, and health-related outcomes. Studies were assessed using the National Institute of Health Critical Appraisal Tools, and findings were synthesized to identify common characteristics of PA interventions and outcomes. Twenty-three studies were included: 15 RCTs and 8 pre/post-test studies. Heterogeneity existed across design, sample demographics, intervention timing, and observed outcomes. The most common characteristics of PA interventions were supervision of PA, wearable device use, tailored/individualized PA prescriptions, and goal setting. PA interventions positively affected health-related outcomes, with 21 studies reporting statistically significant findings. Implementing personalized PA prescriptions, utilizing wearable devices, and incorporating goal setting as characteristics in PA interventions hold potential benefits for AYASCa, leading to improved outcomes. Still, additional research is needed to explore interventions that utilize these PA characteristics and determine which ones are most effective for AYASCa. By further investigating and identifying optimal PA characteristics, interventions can be better tailored to meet this population's specific needs and preferences, ultimately enhancing their overall well-being and recovery.

Unilateral Absent Pulmonary Artery in Pregnancy: A Case Report and Systematic Literature Review

OBJECTIVE

 Unilateral absence of a pulmonary artery (UAPA) is a rare congenital malformation associated with hemoptysis, pulmonary hypertension, and infection. Little is known about the impact on pregnancy outcomes. We sought to synthesize the existing literature on pregnancy outcomes in patients with maternal UAPA.

STUDY DESIGN

 We report a case of maternal UAPA and performed a systematic review of the existing literature. Articles in English reporting pregnancy outcomes among women with unilateral absence or hypoplasia of the pulmonary artery were included. Articles were reviewed at the abstract level and, if eligible, at the full-text level by two independent reviewers with disagreements adjudicated by a third reviewer. Data were abstracted by two independent reviewers. Outcomes of interest were mode of delivery, gestational age at delivery, intensive care admission, maternal death, and length of stay. Summary statistics for each outcome are presented.

RESULTS

 We identified 14 studies, including the presented case, reporting outcomes in 22 pregnancies impacted by maternal UAPA. Median age at diagnosis was 21 years. Concurrent cardiac comorbidities were reported in 6/13 (46.2%) with pulmonary hypertension in 5/20 (25%) of cases where this information was reported. We observed high rates of preterm birth (4/12, 33.3%), cesarean delivery (10/15, 66.7%), and operative vaginal delivery (2/5, 40.0%). There was one maternal death occurring in the immediate postpartum period for a mortality rate of 4.5%.

CONCLUSION

 Our study provides a comprehensive review of existing literature on maternal UAPA. Our findings suggest increased rates of adverse outcomes and underscore the importance of early diagnosis, identification of pulmonary hypertension, and multidisciplinary care.

KEY POINTS

· There may be increased adverse outcomes in maternal UAPA.. · Concurrent cardiac abnormalities are common in maternal UAPA.. · Early diagnosis, identification of pulmonary hypertension, and multidisciplinary care are important..

Parental Decision-Making Around Introducing Complementary Foods: An Integrative Review

A primary role in infant parenting is feeding, and this role undergoes a significant transition when introducing complementary foods (CF), with important long-term health implications. Understanding the influences on parental decision-making around timing the introduction to CF can help health care providers provide parents with effective support for feeding; however, the factors that influence parental decision-making have not been recently reviewed in the United States. To determine influences and information sources, this integrative review examined the literature from 2012 to 2022. Results indicated that parents are confused and distrustful of inconsistent and changing guidelines around CF introduction. Instead, developmental readiness signs may be a more appropriate way for practitioners and researchers to support parents in appropriate CF introduction. Future work is needed to evaluate interpersonal and societal influences on parental decision-making, as well as to develop culturally sensitive practices to support healthful parental decisions.

A Systematic Review of Interpersonal Interactions Related to Racism in Studies Assessing Breast and Gynecological Cancer Health Outcomes Among Black Women

OBJECTIVE

To identify how studies measure racism-related variables at the interpersonal level and identify associated breast and gynecological cancer disparities among Black women.

METHODS

A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Searches were conducted in PubMed, CINAHL Plus, and Scopus using terms centered on racism and cancer. Inclusion criteria consisted of the study being conducted in the USA with Black or African American women and the study stating an outcome or focus identified as a breast or gynecological cancer health disparity. Two researchers independently screened titles and abstracts and full texts articles and completed quality assessments of included studies. Data were extracted into a matrix table, and common concepts were identified and synthesized using the matrix method. The quality of included studies was assessed using the Joanna Briggs Institute's critical appraisal tools.

RESULTS

Thirteen studies that examined the effect of racism-related variables operating at the interpersonal level on breast, cervical, and ovarian cancer outcomes in Black women were identified for inclusion. Across studies, racism-related variables were measured as discrimination, trust, racism, and clinician-patient interactions. Additionally, across studies, disparities were identified in cancer screening, treatment received, survivorship quality of life, and incidence.

CONCLUSION

This review highlights the need for valid, reliable, and consistent measurement of racism operating at the interpersonal level to first understand its impact on cancer health disparities and to also facilitate the development and evaluation of interventions aimed at mitigating interpersonal-level racism.

Quality and safety education for nurses: A bibliometric analysis

PURPOSE

Since its origin in the United States in 2005, Quality and Safety Education for Nurses (QSEN) has guided nurses' preparation for alleviating preventable harm and improving quality safe care. QSEN's value is illustrated through specific inclusion in the competency-based 2021 American Association for Colleges of Nursing (AACN) Essentials. The purpose of this bibliometric analysis is to explore publication patterns of the extant QSEN literature to assess QSEN's spread and global penetration and to map the available knowledge and data regarding quality and safety education for nurses.

DESIGN

Bibliometric analysis.

METHOD

Two QSEN investigators and two health science librarians completed database searches to identify articles with keywords QSEN or Quality and safety education for nursing. Inclusion criteria were (1) QSEN-specific and (2) published in a peer-reviewed journal. Using PRISMA screening, the final sample included 221 articles between 2007 and 2021.

RESULTS

Average annual QSEN publications was 14.5 articles; the highest was 26 publications in 2017. Article types were 84 research, 77 descriptive/reviews, 28 quality improvement projects or case studies, 20 statements, and 12 editorials. Focus analysis revealed 165 education articles, 35 clinical practice, 17 professional development, and 4 leadership/administration. Fourteen journals published three or more; eight were education journals. Nine topic clusters indicated areas of publication focus, including clinical teaching, simulations, performance, context, and criteria of analysis, factors of efficacy, innovation and advanced practice, patient care and outcomes, academic concepts, and research frameworks.

CONCLUSIONS

Results reveal far less QSEN penetration for guiding professional practice, research measuring outcomes and impact, and global collaboration to examine cultural implications for diversity and inclusion. Results present future recommendations to assure all nurses worldwide have access to competency development to alleviate preventable healthcare harm.

CLINICAL RELEVANCE

Originating in the United States (US), the QSEN project provided the seminal framework for transforming education and practice through defining the six quality and safety competencies (patient-centered care, teamwork and collaboration, evidence-based practice, quality improvement, safety, and informatics) essential to alleviate preventable healthcare harm. Results reveal opportunities to advance QSEN penetration in developing professional practice, guiding research measuring outcomes and impact, and extending global collaboration to examine cultural implications for diversity and inclusion.

Characteristics of health care interventions in affordable senior housing: A scoping review

AIMS

Older adults in affordable senior housing often experience chronic illness and unmet health care needs. This review describes studies reporting the characteristics and primary outcomes of health care interventions for older adults living in affordable senior housing.

DESIGN

A scoping review METHODS: After a systematic search in three databases, a team of investigators screened 1,284 titles and abstracts and selected 31 records with reports on 28 studies for review. Narrative synthesis was used to describe studies of interventions in senior housing and primary outcomes.

RESULTS

Studies typically used observational designs and added clinical staff, such as nurses and social workers, to provide health care interventions in groups (n = 15) or with individuals (n = 13). Outcomes were classified in four groups: wellness, symptom management, health care use, and physical function. A subset of 23 studies (82.1%) reported effective interventions.

IMPACT

Findings identify innovative interventions to promote health in affordable senior housing.

Psychosocial Experiences of Cancer Survivors and their Caregivers in sub-Saharan Africa: A Synthesis of Qualitative Studies

OBJECTIVE

To synthesize and examine current literature on survivorship experiences and psychosocial oncologic care programs of individuals affected by cancer in sub-Saharan Africa (SSA).

METHODS

This was a systematic review guided by the PRISMA 2020 guidelines. We searched 6 databases for articles published from inception to October 21, 2021. Articles were appraised using the Johanna Briggs Institute's Checklist for Qualitative Research. For data synthesis, we used the World Health Organization (WHO) quality of life framework [WHOQOL] to organize experiences into 6 domains/themes.

RESULTS

Twenty-five qualitative studies were included in the synthesis. Studies focused on psychosocial care of adults (>18 years) affected by cancer in SSA. The common WHOQOL domains were social relations, spirituality/religion/personal beliefs, and psychological.

CONCLUSION

Findings echo need for individuals with cancer and their caregivers. Healthcare professionals are an essential resource for information and support services that can be tailored to individuals need. This synthesis highlighted caregiver stress and stressors from the community that could impact care of individuals with cancer. A holistic approach is needed that incorporates professional and social aspects of care. This article is protected by copyright. All rights reserved.

Mapping definitions, measures and methodologies of assessing police violence in the health literature: a scoping review protocol

INTRODUCTION

Police violence is a growing public health issue in the USA. Emerging evidence suggests that negative police encounters are associated with adverse physical and mental health outcomes. There is a critical need to examine the relationship between police violence and health disparities. However, the lack of consensus on a conceptual and operational definition of police violence is a limitation in scientific investigations on police violence and its health impacts. Here, we present the protocol for a scoping review that maps definitions, measures and methodologies of assessing police violence in the health literature.

METHODS AND ANALYSIS

We will comprehensively search PubMed, Cumulative Index to Nursing and Allied Health Literature and APA PsycInfo databases. We will use the following string of key terms separated with the Boolean operator 'or': 'police violence', 'police brutality', 'police use of force', 'law enforcement violence', 'law enforcement brutality', 'law enforcement use of force' and 'legal intervention'. An English language limit will be applied. We will include studies published in English or that have an English language abstract available. Eligible studies will include: (1) a definition of police violence and/or (2) a measurement of police violence.

ETHICS AND DISSEMINATION

This scoping review does not require ethical approval. The findings of this review will be disseminated through publication in a peer-reviewed journal and at conferences.

Family-based psychosocial interventions for adult Latino patients with cancer and their caregivers: A systematic review

Objective

This review aimed to systematically examine the characteristics and outcomes of family-based psychosocial interventions offered to adult Latino patients with cancer and their caregivers.

Methods

We searched six databases from their inception dates through June 2022. Studies were eligible for inclusion if they (1) targeted both adult Latino patients diagnosed with cancer and their adult caregivers or reported subgroup analyses of Latino patients and caregivers; (2) included family-based psychosocial interventions; (3) used randomized controlled trial (RCT) or quasi-experimental designs; and (4) were published in English, Spanish or Portuguese. Members of our multidisciplinary team assessed the risk of bias in the reviewed studies using the Cochrane Collaboration's Risk of Bias Tool.

Results

Our database searches yielded five studies. The studies were conducted in the U.S. and Brazil. Three studies were RCTs, and two used quasi-experimental designs. The sample sizes ranged from 18 to 230 patient-caregiver dyads. These studies culturally adapted the intervention contents and implementation methods and involved bilingual interventionists. The interventions had beneficial effects on multiple aspects of psychosocial outcomes for both patients and caregivers. We also identified methodological limitations in the reviewed studies.

Conclusions

Findings from this systematic review help deepen our understanding of family-based psychosocial interventions for Latinos affected by cancer. The small number of psychosocial interventions focused on adult Latino cancer patients and their caregivers is concerning, considering that Latino populations are disproportionally burdened by cancer. Future research needs to design and evaluate culturally-appropriate interventions to support Latino patients and families who cope with cancer.

Systematic review of psychosocial interventions for adult cancer patients and their family caregivers in Sub-Saharan Africa

Cancer is becoming a public health issue in the Sub-Saharan Africa (SSA). This systematic review aims to synthesise psychosocial interventions and their effects on the health outcomes of adult cancer patients and their family caregivers in SSA. We identified eligible publications in English language from PubMed, Cumulative Index of Nursing and Allied Health Literature Plus with Full Text, Embase, APA PsycInfo, Scopus, and African Index Medicus databases. We included psychosocial interventions targeted adult cancer patients/survivors or their family caregivers in SSA. This review identified five psychosocial interventions from six studies that support adult cancer patients and their family caregivers in SSA. The interventions focused on providing informational, psycho-cognitive, and social support. Three interventions significantly improved quality of life outcomes for cancer patients and their caregivers. Significant gaps exist between the rapidly increasing cancer burdens and the limited psychosocial educational interventions supporting adult cancer patients and their families in SSA. The reviewed studies provide preliminary evidence on development and testing interventions that aim to improve patients' and caregivers' quality of life.

Systematic Review of the Relation Between Feeding Problems and Sensory Processing in Children With Autism Spectrum Disorder

PURPOSE

Many studies have linked sensory sensitivities to feeding problems in children with autism spectrum disorder (ASD). Despite the importance of sensory processing for a variety of mealtime and eating skills, the specific sensory processes that may impact feeding problems in children with ASD have not been comprehensively reviewed. Thus, the goal of this systematic review was to understand the associations between sensory processing and feeding difficulties in children with ASD.

METHOD

This systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed, CINAHL Plus with Full Text (EBSCOhost), Scopus (Elsevier), and Embase (Elsevier) databases were searched from their dates of inception through the final search date of April 19, 2022, for English language studies that examined both sensory processing and feeding among children with ASD. Studies were assessed for quality using the Joanna Briggs Institute critical appraisal tools.

RESULTS

A total of 27 studies were included. Findings supported the existence of a relationship between sensory processing and feeding problems in children with ASD. Specifically, studies reported that overall scores on sensory processing measures as well as measures of oral sensory processing were frequently associated with feeding problems.

CONCLUSIONS

This review supports the development of future feeding interventions focusing on sensory processing given the relationship between sensory processing and feeding problems among children with ASD. Future research should focus on utilizing consistent feeding assessments specific to children with ASD and collect information on medical diagnoses that can impact feeding in order to report on feeding more holistically in this population.

Post-Traumatic Stress Disorder and Post-Traumatic Growth following Kidney Transplantation

Background

Kidney transplantation (KT) is a life-saving therapy for kidney failure. However, KT recipients can suffer from debilitating depression, post-traumatic stress disorder (PTSD), and suicide. In contrast to PTSD, post-traumatic growth (PTG) is a positive psychologic change in response to a challenging situation. PTG has been studied in other chronic diseases, but less is known about its role in the setting of KT. We sought to elucidate the prevalence, predictors, and the effect of PTSD and PTG on post-KT outcomes. We also considered the roles of benefit finding and resilience.

Methods

In a literature review, we identified publications that examined PTSD, PTG, benefit finding, and/or resilience in KT recipients. We excluded case reports and first-person narratives. Publications meeting the specified criteria after full text review underwent data abstraction and descriptive analysis.

Results

Of the 1013 unique citations identified, 39 publications met our criteria. PTSD was the most common construct evaluated (16 publications). Resilience was studied in 11 publications, PTG in nine, and benefit finding in five. Up to 21% of adult and 42% of pediatric KT recipients may experience PTSD, which is associated with lower quality of life (QOL), impaired sleep, and other psychiatric comorbidity. PTG was associated with improved QOL, kidney function, and reduced risk of organ rejection. Although benefit finding tended to increase post KT, resilience remained stable post KT. Like PTG, resilience was associated with lower psychologic distress and increased treatment adherence and confidence in the health care team.

Conclusions

PTG, resilience, and benefit finding appear to reduce the risk of PTSD, promote well-being, and reduce risk of graft failure in KT recipients. Future research to understand these relationships better will allow clinicians and researchers to develop interventions to promote PTG, resilience, and benefit finding, and potentially improve post-transplant outcomes such as adherence and reducing risk of organ rejection.

A bibliometric analysis of nursing and midwifery research in the Caribbean

PURPOSE

To determine the research output of Caribbean nurses and midwives.

METHODS

We searched the Scopus database to identify publications by Caribbean nurses and midwives during the period 2000-2020. Publications were included in the analysis if they had at least one author who was either a nurse or midwife and affiliated with a Caribbean geographic location. All publication types and languages were included in the analysis. Organization analysis and collaboration networks were created using the VOS Viewer application.

FINDINGS

The number of Scopus publications by Caribbean nurses and midwives progressively grew from 22 in 2000 to 584 in 2020. Cuba recorded the highest number of nursing research publications (319) followed by Jamaica (92), and Puerto Rico (59). Most publishing institutions were universities. The University of the West Indies (Jamaica) ranked highest with 15.2% of publications, followed by Universidad de Ciencias Médicas de La Habana with 14.4% of publications, Universidad de Puerto Rico ranked third with 9.8% of publications. The majority of publications (83.6%) were peer reviewed research articles, while review articles accounted for 9.8% of publications. Six out of the ten journals that published most research done by Caribbean nurse researchers were Cuban journals which published a total of n = 250 (75.8%) articles. All six journals had no impact factor and had low cite scores.

CONCLUSIONS

Our analysis of bibliometric indicators suggest that recent and steady growth in nursing and midwifery research in the Caribbean has had low visibility. Equipping nurses and midwives with the necessary knowledge and skills to lead, teach, and conduct high quality research through doctorate level education is an imperative for increasing research productivity among Caribbean nurses and midwives.

CLINICAL RELEVANCE

Nursing and midwifery research is critical for evidence-based nursing and midwifery practice. High quality and context specific research evidence will enable Caribbean nurses and midwives to provide quality and culturally sensitive nursing and midwifery care and contribute to evidence informed policy decisions.

Quality of life among patients with cancer and their family caregivers in the Sub-Saharan region: A systematic review of quantitative studies

Guided by the World Health Organization quality of life (WHOQOL) framework, this systematic review aimed to examine evidence about the prevalence and severity of QOL-related health problems and their influencing factors in Sub-Saharan Africa (SSA). We identified eligible publications in English language from PubMed, Cumulative Index of Nursing and Allied Health Literature Plus with Full Text, Embase, APA PsycInfo, Scopus, and African Index Medicus databases. We included quantitative descriptive studies that measured overall and subdomains of QOL as the outcome in adult patients/survivors with cancer in SSA. Twenty-six descriptive cross-sectional studies (27 papers) that were conducted since 1988 in different SSA countries among patients with various types of cancer met our inclusion criteria. We found inconsistencies in how the prevalence and severity of QOL-related health problems have been researched and reported across studies, which complicated comparing findings and drawing conclusions. The most common factors that influenced the overall and subdomains of QOL included coping; internal and external locus of control; symptoms and symptom management; and religious beliefs and religious care. Demographics (e.g., age and marital status), cancer-related factors (cancer stage and type of treatment), and social determinants of health (e.g., education, access to information and resources, financial distress, and urban vs rural residency) also impacted QOL and its subdomains. Our findings indicate the significant need for recognizing and managing QOL-related problems for cancer patients and caregivers in SSA. Research needs to use culturally adapted, standardized assessment tools and analysis approaches to better understand the QOL challenges this population faces. Comprehensive supportive care is needed to address the complex QOL issues in resource-limited SSA.

Systematic Review of Cognitive Impairment in Colorectal Cancer Survivors Who Received Chemotherapy

PROBLEM IDENTIFICATION

Cognitive impairment is a common and troublesome side effect experienced by many cancer survivors. It can have a significant impact on survivors' ability to function and enjoy a high quality of life. However, most cognitive impairment research has focused on breast cancer survivors, despite the high rates of colorectal cancer and the toxicity of treatment agents in some colorectal cancer chemotherapeutic regimens, which have been linked to cognitive impairment. This review provides a novel synthesis of what is known about cognitive impairment in colorectal cancer survivors.

LITERATURE SEARCH

CINAHL®, Cochrane Library, Embase®, PsycINFO®, and PubMed® were systematically searched by a health sciences librarian.

DATA EVALUATION

Data were extracted across studies; findings about the prevalence, severity, and correlates of cognitive impairment were synthesized.

SYNTHESIS

Across findings from 26 articles representing 24 independent studies, 13%-57% of participants had cognitive impairment. Potential demographic, physiologic, and psychological correlates of cognitive impairment were identified.

IMPLICATIONS FOR PRACTICE

Findings indicate a need to focus research and patient assessments on early identification of risk factors, assessing for existing cognitive deficits and testing interventions to decrease cognitive impairment in colorectal cancer survivors.

A Systematic Review on Outcomes of Preterm Small for Gestational Infants Born to Women With Hypertensive Disorders in Pregnancy

There is a lack of knowledge on the intersection between prematurity, small for gestational age, and hypertensive disorders of pregnancy (HDP). Therefore, the aim of this systematic review was to examine the outcomes of preterm infants who were small for gestational age born to women with HDP. Searches were conducted with no date restriction through the final search date of May 13, 2020, in the following databases: PubMed, Web of Science Core Collection, Cumulative Index of Nursing and Allied Health Literature Plus with Full Text (EBSCOhost), and Embase (Elsevier). A total of 6 studies were eligible for this review. The adjusted odds of mortality and necrotizing enterocolitis were significantly lower in the pregnancy-induced hypertension (PIH)/HDP group than in the non-PIH/HDP group. There was no significant difference in the odds of respiratory distress syndrome, bronchopulmonary dysplasia, and intraventricular hemorrhage between PIH/HDP and non-PIH/HDP groups. There was no significant difference between PIH/HDP and non-PIH/HDP groups in cystic periventricular leukomalacia, retinopathy of prematurity, late-onset sepsis, patent ductus arteriosus, length of hospital stays, duration of supplemental oxygen use, duration of mechanical ventilation, and continuous airway pressure. The studies included in this systematic review demonstrated that PIH/HDP is associated with lower infant mortality and necrotizing enterocolitis.

Building a Bridge: A Review of Information Literacy in Nursing Education

BACKGROUND

Although information literacy (IL) has been valuable in nursing education, guiding documents from librarianship (e.g., Framework for Information Literacy in Higher Education) remain relatively obscure among nursing faculty. This review analyzes the intersection of IL with nursing and offers analyses for a better understanding of integrating IL into nursing education settings.

METHOD

Scholarly literature was searched, and Covidence was used to track themes regarding how (and where) IL literature (n = 179) connects to nursing educational settings.

RESULTS

Librarians are not involved consistently within nursing education. Research and discussion on IL in nursing are published in librarianship, education, and health sciences literature, and the terminology does not always align across these disciplines.

CONCLUSION

Findings indicate an opportunity for librarians to share the Framework and its connections to the research literature with the nursing community. Researchers share suggestions for how common themes, language, and ideas can be shared between librarians and nursing faculty. [J Nurs Educ. 2021;60(8):431-436.].

Evaluating nursing faculty's approach to information literacy instruction: a multi-institutional study

Objective

In 2018, the Association of College & Research Libraries (ACRL) Health Sciences Interest Group convened a working group to update the 2013 Information Literacy Competency Standards for Nursing to be a companion document to the 2016 Framework for Information Literacy in Higher Education. To create this companion document, the working group first needed to understand how nursing faculty approached information literacy (IL) instruction.

Methods

The working group designed a survey that assessed how nursing faculty utilized IL principles in coursework and instruction. The survey consisted of nineteen mixed methods questions and was distributed to nursing faculty at eight institutions across the United States.

Results

Most (79%) faculty indicated that they use a variety of methods to teach IL principles in their courses. While only 12% of faculty incorporated a version of the ACRL IL competencies in course design, they were much more likely to integrate nursing educational association standards. Faculty perceptions of the relevance of IL skills increased as the education level being taught increased.

Conclusion

The integration of IL instruction into nursing education has mostly been achieved through using standards from nursing educational associations. Understanding these standards and understanding how faculty perceptions of the relevance of IL skills change with educational levels will guide the development of a companion document that librarians can use to collaborate with nurse educators to integrate IL instruction throughout nursing curriculums at course and program levels.

A Systematic Review of Physical Health Consequences and Acculturation Stress Among Latinx Individuals in the United States

The health of Latinx immigrants decays over time and across generations. Acculturation stress influences decays in behavioral and mental health in this population, but the effect on physical health outcomes is less understood. This systematic review synthesizes findings from 22 studies that examined the influence of acculturation stress on physical health outcomes among Latinx populations in the United States. The Society-to-Cell Resilience Framework was used to synthesize findings according to individual, physiological, and cellular levels. There is mounting evidence identifying acculturation stress as an important social contributor to negative physical health outcomes, especially at the individual level. More research is needed to identify the physiological and cellular mechanisms involved. Interventions are also needed to address the damaging effects of acculturation stress on a variety of physical health conditions in this population.

A Systematic Review of Randomized Trials Investigating Methods of Postoperative Void Trials Following Benign Gynecologic and Urogynecologic Surgeries

OBJECTIVE

To perform a systematic review of randomized controlled trials (RCTs) studying postoperative void trials (VTs) following gynecologic and urogynecologic surgery to investigate (1) the optimal postoperative VT methodology and (2) the optimal time after surgery to perform a VT.

DATA SOURCES

PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov.

METHOD OF STUDY SELECTION

We systematically searched the aforementioned data sources from inception to November 22, 2019, using a combination of subject headings and keywords for the following 3 concepts: gynecologic surgery (prolapse, benign gynecologic, and incontinence surgery), postoperative period, and voiding. We identified any RCT in English that studied VT methodology or timing in patients undergoing benign gynecologic or urogynecologic surgery. Discrepancies were adjudicated by a third reviewer. We followed the standard systematic review methodology and used the Jadad scoring system to assess bias. Extracted study outcomes included the following: proportion of patients discharged home with catheter, proportion of VT failure, surgery for retention, retention after initial VT, postoperative calls and visits, time in postanesthesia care unit (PACU), time to discharge, time to spontaneous void, duration of catheterization, patient and provider burden, and urinary tract infection (UTI).

TABULATION, INTEGRATION, AND RESULTS

We double screened 618 abstracts and clinical trial descriptions, assessed 56 full-text articles, and ultimately included 21 RCTs. The evidence was of low to moderate quality overall. The studies were divided into the following 2 categories: VT methodology (10 studies) and VT timing (11 studies). VT methodology included backfill-assisted (in operating room vs PACU), autofill, and force of stream studies. One RCT compared backfill-assisted with and without postvoid residual volume check. Outcomes were similar for all VT methods, except backfill-assisted decreased time to spontaneous void compared with autofill. In the VT timing category, earlier VT performance correlated with a shorter time to discharge, time to spontaneous void, duration of catheterization, and lower patient burden and UTI rate but had a higher rate of retention after initial VT. There was no difference between earlier vs later VT timing for proportion of discharged home with catheter or rate of VT failure. No studies reported outcomes of provider burden or postoperative calls.

CONCLUSION

In comparing VT methodologies, VT by backfill-assisted (in operating room vs PACU, ± postvoid residual volume), autofill, and force of stream resulted in similar outcomes with no one method being superior. Performing VT at an earlier postoperative time point results in shorter time to discharge and spontaneous void, shorter duration of catheterization, lower patient burden, and lower UTI risk, but it may increase the risk of retention after initial VT.

Avoiding predatory journals: Quick peer review processes too good to be true

PROBLEM

Nursing is experiencing the growth of predatory journals with questionable peer review processes. These journals publish submissions quickly and do not enhance the authors' reputation and scholarship of nursing.

METHODS

A qualitative, descriptive study design examined the legitimacy of the peer-review process described on the websites of predatory nursing journals. Posted review processes (n = 53) were examined for quality indicators related to language use, author control, and transparency.

FINDINGS

Of the 53 predatory nursing journals describing a peer-review process, the majority indicated that all submitted content was sent for peer review (n = 34, 64.15%). Most journals did not describe the criteria on which submitted articles would be evaluated ( n = 39, 73.58%). Quality indicators for language included multiple grammatical errors and odd language and phrases ( n = 39, 73.58%). Author control of tracking, revisions, and review of galley proofs were inconsistent in the described peer-review processes. The majority did not provide a way to track a manuscript through the process ( n = 29, 54.72%). Most journals did not explain the types of peer review they conducted ( n = 31, 58.49%).

CONCLUSION

Authors can sidestep the trap of publishing in predatory journals by paying attention to the peer review process when selecting a journal for publication.

Learning Cybercivility: A Qualitative Needs Assessment of Health Professions Students

BACKGROUND

Literature on cyberincivility in health professions education has mainly focused on intraprofessional communication. This study explored health professions students' experiences with cyberincivility, as well as their perspectives on interprofessional cybercivility learning.

METHOD

This qualitative study used semistructured interviews with a purposive sample of 25 students in nursing, medicine, physician assistant, or physical therapy programs at a private university in the United States. Thematic analysis was used to identify recurrent patterns in the data.

RESULTS

Students defined cyberincivility in various ways and shared experiences of uncivil communication in virtual communities. They also expressed great interest in learning cybercivility in the context of interprofessional education. Diverse learning preferences were suggested.

CONCLUSION

This study highlights the importance and benefits of establishing interprofessional cybercivility learning programs to improve student interactions in the virtual environment. Future research should explore professional differences and similarities in how learners experience cyberincivility and its influence on their roles as future health care providers.

Cyberincivility in the Massive Open Online Course Learning Environment: Data-Mining Study

BACKGROUND

Cyberincivility is a pervasive issue that demands upfront thinking and can negatively impact one's personal, professional, social, and educational well-being. Although massive open online courses (MOOCs) environments could be vulnerable to undesirable acts of incivility among students, no study has explored the phenomena of cyberincivility in this learning environment, particularly in a health-related course in which mostly current or eventual health professions students enroll.

OBJECTIVE

This study aimed to analyze the characteristics of text entries posted by students enrolled in a medicine and health care MOOC. The objectives were to (1) examine the prevalence of posts deemed disrespectful, insensitive or disruptive, and inconducive to learning; (2) describe the patterns and types of uncivil posts; and (3) highlight aspects that could be useful for MOOC designers and educators to build a culture of cybercivility in the MOOC environment.

METHODS

We obtained data from postings in the discussion forums from the MOOC Medical Neuroscience created by a large private university in the southeast region of the United States. After cleaning the dataset, 8705 posts were analyzed, which contained (1) 667 questions that received no responses; (2) 756 questions that received at least one answer; (3) 6921 responses that applied to 756 posts; and (4) 361 responses where the initiating post was unknown. An iterative process of coding, discussion, and revision was conducted to develop a series of a priori codes. Data management and analysis were performed with NVivo 12.

RESULTS

Overall, 19 a priori codes were retained from 25 initially developed, and 3 themes emerged from the data-Annoyance, Disruption, and Aggression. Of 8705 posts included in the analysis, 7333 (84.24%) were considered as the absence of uncivil posts and 1043 (11.98%) as the presence of uncivil posts, while 329 (3.78%) were uncodable. Of 1043 uncivil posts analyzed, 466 were coded to >1 a priori codes, which resulted in 1509 instances. Of those 1509 instances, 826 (54.74%) fell into "annoyance", 648 (42.94%) into "disruption", and 35 (2.32%) into "aggression". Of 466 posts that related to >1 a priori codes, 380 were attributed to 2 or 3 themes. Of those 380 posts, 352 (92.6%) overlapped both "annoyance" and "disruption," 13 (3.4%) overlapped both "disruption" and "aggression," and 9 (2.4%) overlapped "annoyance" and "aggression," while 6 (1.6%) intersected all 3 themes.

CONCLUSIONS

This study reports on the phenomena of cyberincivility in health-related MOOCs toward the education of future health care professionals. Despite the general view that discussion forums are a staple of the MOOC delivery system, students cite discussion forums as a source of frustration for their potential to contain uncivil posts. Therefore, MOOC developers and instructors should consider ways to maintain a civil discourse within discussion forums.

Uncovering cyberincivility among nurses and nursing students on Twitter: A data mining study

BACKGROUND

Although misuse of social networking sites, particularly Twitter, has occurred, little is known about the prevalence, content, and characteristics of uncivil tweets posted by nurses and nursing students.

OBJECTIVE

The aim of this study was to describe the characteristics of tweets posted by nurses and nursing students on Twitter with a focus on cyberincivility.

METHOD

A cross-sectional, data-mining study was held from February through April 2017. Using a data-mining tool, we extracted quantitative and qualitative data from a sample of 163 self-identified nurses and nursing students on Twitter. The analysis of 8934 tweets was performed by a combination of SAS 9.4 for descriptive and inferential statistics including logistic regression and NVivo 11 to derive descriptive patterns of unstructured textual data.

FINDINGS

We categorized 413 tweets (4.62%, n = 8934) as uncivil. Of these, 240 (58%) were related to nursing and the other 173 (42%) to personal life. Of the 163 unique users, 60 (36.8%) generated those 413 uncivil posts, tweeting inappropriately at least once over a period of six weeks. Most uncivil tweets contained profanity (n = 135, 32.7%), sexually explicit or suggestive material (n = 37, 9.0%), name-calling (n = 14, 3.4%), and discriminatory remarks against minorities (n = 9, 2.2%). Other uncivil content included product promotion, demeaning comments toward patients, aggression toward health professionals, and HIPAA violations.

CONCLUSION

Nurses and nursing students share uncivil tweets that could tarnish the image of the profession and violate codes of ethics. Individual, interpersonal, and institutional efforts should be made to foster a culture of cybercivility.

Strategies for Integrating Technology as a Team Member

Interdisciplinary health care teams have numerous opportunities to investigate more efficient health care delivery mechanisms using technology that bridges information science and human-centered care. At the onset of team formation, technology can be strategically integrated to enhance health care delivery for patients and providers using multiple strategies.

Guidance Provided to Authors on Citing and Formatting References in Nursing Journals

Reference citations should be accurate, complete, and presented in a consistent format. This study analyzed information provided to authors on preparing citations and references for manuscripts submitted to nursing journals (n = 209). Half of the journals used the American Psychological Association reference style. Slightly more than half provided examples of how to cite articles and books; there were fewer examples of citing websites and online journals. Suggestions on improving accuracy of references are discussed.

Quality of Author Guidelines in Nursing Journals

Purpose

The aims of this study were to (a) describe the information provided in author guidelines in nursing journals, (b) assess the completeness of this information, and (c) identify the extent and types of reporting guidelines used in nursing journals.

Design

Content analysis of author guidelines for 245 nursing journals included in the Directory of Nursing Journals maintained at the International Academy of Nursing Editors website.

Methods

Using Research Electronic Data Capture, data on 19 criteria for completeness were extracted from published author guidelines. Additional details about journal requirements, such as allowed length of manuscripts and format for the abstract, were also recorded. Reliability was established by simultaneous review of 25 journals (10%) by the research assistant and a senior member of the research team.

Findings

Author guidelines were easily accessible at journal websites or through links to download the information. A majority (73.5%) had completeness scores of 75% or higher; six journals had guidelines that were 100% complete. Half of the journals used the American Psychological Association reference style, and 26.3% used the American Medical Association style. Less than one fourth had stated requirements to use reporting guidelines such as Consolidated Standards of Reporting Trials (CONSORT) and Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA).

Conclusions

Author guidelines for nursing journals are generally complete and informative. Although specific reporting guidelines such as CONSORT and PRISMA improve the accuracy and completeness of manuscripts on various types of studies, most nursing journals do not indicate use of these for manuscript preparation. Editors who want to improve their author guidelines should use the 19 criteria for completeness as a gauge for updating and revision.

Clinical Relevance

Nurses rely on the published literature to inform their practice and ensure that it is based on evidence. Guidelines for publishing in the scholarly literature assist clinicians and scholars to ensure that published articles are complete, current, concise, and accurate.

Student evaluations of teaching (SET): Guidelines for their use

Student evaluations of teaching (SET) provide a structured way of collecting feedback from students about the course and teacher's effectiveness. We reviewed literature describing use of SET across a broad range of disciplines in undergraduate and graduate education to provide guidelines for faculty in using SET in a nursing or other health professions program. On SET tools, students typically rate their satisfaction with a course and perceptions about the quality of the teaching. It is important to evaluate SET tools prior to their use including pilot testing tools with students because studies show students may not interpret items or questions on a SET tool as faculty intended. Common uses of the evaluation data from SET include improvement of courses and teaching, and for personnel decisions.

Social media use and cybercivility guidelines in U.S. nursing schools: A review of websites

This research analyzes to what extent U.S. nursing schools use social media, their policies or guidelines on cybercivility in social media, online classrooms, and email correspondence, and whether these protocols are readily available to students. This website-based study employs a descriptive, cross-sectional, non-experimental search design. Data were collected in nursing schools offering master's programs (n=197) and online graduate programs in master's degree (n=110) listed in the 2017 edition of U.S. News and World Report. School ranking was positively correlated with the total number of social networking sites being used in the schools, but not with the presence of cybercivility guidelines. About a third of the nursing schools in the sample had policies/guidelines concerning social media, while fewer than 10% had policies/guidelines about online classroom conduct (n=14) or email use (n=16). Key features of these protocols were professionalism, expected behaviors, and consequences. Establishing and implementing policies and guidelines regarding cybercivility is a vital step to promote a culture of civility online. It is especially important to do so in nursing schools where standards should reflect the values of the profession.

Quality of articles published in predatory nursing journals

BACKGROUND

Predatory journals exist in nursing and lack the safeguards of traditional publishing practices.

PURPOSE

To examine the quality of articles published in predatory nursing journals.

METHOD

Randomly selected articles (n = 358) were reviewed for structural content and eight quality indicators.

FINDINGS

Two-thirds (67.4%) of the articles were published between 2014 and 2016, demonstrating the acceleration of publications in predatory nursing journals. The majority (75.9%) of the articles were research reports. Most followed the IMRAD presentation of a research report but contained errors, or the study was not pertinent to the nursing discipline.

CONCLUSIONS

Nursing research published in predatory journals may appear legitimate by conforming to an expected structure. However, a lack of quality is apparent, representing inadequate peer review and editorial processes. Poor quality research erodes the scholarly nursing literature.

Closing the loop on nursing library instruction: using student performance to improve outcomes

Two librarians analyzed nursing students' performance on an information literacy assignment to determine how they could change their instruction to better assist the students in comprehending the material. After identifying major areas of difficulty, including the use of search techniques, they revised both the instruction and the assignment, closing the loop by utilizing their assessment data. Next, they analyzed those results to evaluate the effectiveness of their changes and to make further improvements, thus demonstrating the iterative nature of instruction and assessment. The evidence-based instruction cycle of teaching, assessing, and revising should be repeated frequently to keep the assignment fresh and relevant.

Evaluation of esophageal motor function in clinical practice

Esophageal motor function is highly coordinated between central and enteric nervous systems and the esophageal musculature, which consists of proximal skeletal and distal smooth muscle in three functional regions, the upper and lower esophageal sphincters, and the esophageal body. While upper endoscopy is useful in evaluating for structural disorders of the esophagus, barium esophagography, radionuclide transit studies, and esophageal intraluminal impedance evaluate esophageal transit and partially assess motor function. However, esophageal manometry is the test of choice for the evaluation of esophageal motor function. In recent years, high-resolution manometry (HRM) has streamlined the process of acquisition and display of esophageal pressure data, while uncovering hitherto unrecognized esophageal physiologic mechanisms and pathophysiologic patterns. New algorithms have been devised for analysis and reporting of esophageal pressure topography from HRM. The clinical value of HRM extends to the pediatric population, and complements preoperative evaluation prior to foregut surgery. Provocative maneuvers during HRM may add to the assessment of esophageal motor function. The addition of impedance to HRM provides bolus transit data, but impact on clinical management remains unclear. Emerging techniques such as 3-D HRM and impedance planimetry show promise in the assessment of esophageal sphincter function and esophageal biomechanics.

The effects of methane and hydrogen gases produced by enteric bacteria on ileal motility and colonic transit time

BACKGROUND

Gases produced by intestinal flora may modulate intestinal motor function in healthy individuals as well as those with functional bowel disease. Methane, produced by enteric bacteria in the human gut, is associated with slowed intestinal transit and constipation. The effects of hydrogen, another main gas produced by bacterial fermentation in the gut, on small bowel and colonic motor function remains unrecognized. Therefore, we set out to investigate whether intestinal gases including methane and hydrogen could influence the small bowel motility and colonic transit.

METHODS

Guinea pig ileum was placed in the peristaltic bath with tension transducers attached to measure velocity and amplitude of peristaltic contraction before and after the infusion of control, hydrogen, and methane gases. Also, changes in the intraluminal pressures were monitored before and after the gas infusions.

KEY RESULTS

Methane decreased peristaltic velocity and increased contraction amplitude significantly of guinea pig ileum (P < 0.05). The AUC of intraluminal pressure was significantly increased with methane in guinea pig ileum (P < 0.05). In a second experiment, guinea pig colon was placed in the peristaltic bath to measure transit time before and after control, hydrogen, methane, and methane-hydrogen mixture gas infusions. Hydrogen shortened colonic transit time by 47% in the proximal colon, and by 10% in the distal colon, when compared with baselines (P < 0.05).

CONCLUSIONS & INFERENCES

Methane delayed ileal peristaltic conduction velocity by augmenting contractility. Hydrogen shortened colonic transit, and that effect was more prominent in the proximal colon than distal colon.

Efficacy of the glucagon-like peptide-1 agonist exenatide in the treatment of short bowel syndrome

BACKGROUND

Short bowel syndrome (SBS) is a serious clinical disorder characterized by diarrhea and nutritional deprivation. Glucagon-like peptide-1 (GLP-1) is a key hormone, produced by L-cells in the ileum, that regulates proximal gut transit. When extensive ileal resection occurs, as in SBS, GLP-1 levels may be deficient. In this study, we test whether the use of GLP-1 agonist exenatide can improve the nutritional state and intestinal symptoms of patients with SBS.

METHODS

Five consecutive patients with SBS based on ≤90 cm of small bowel and clinical evidence of nutritional deprivation were selected. Baseline SBS symptoms, demographic and laboratory data were obtained. Antroduodenal manometry was performed on each subject. Each patient was then started on exenatide and over the following month, the baseline parameters were repeated.

KEY RESULTS

The subjects consisted of four males and one female, aged 46-69 years. At baseline, all had severe diarrhea that ranged from 6 to 15 bowel movements per day, often occurring within minutes of eating. After exenatide, all five patients had immediate improvement in bowel frequency and form; bowel movements were no longer meal-related. Total parenteral nutrition was stopped successfully in three patients. Antroduodenal manometry revealed continuous low amplitude gastric contractions during fasting which completely normalized with exenatide.

CONCLUSIONS & INFERENCES

Exenatide is a novel and safe treatment option for SBS. It produced substantial improvement in the bowel habits, nutritional status and quality of life of SBS patients. Successful treatment with exenatide may significantly reduce the need for parenteral nutrition and small bowel transplant.

Redefining the role of lymphocytes in gastroesophageal reflux disease and eosinophilic esophagitis

Eosinophilic esophagitis (EoE) and reflux esophagitis (RE) overlap clinically and histologically. RE is characterized by epithelial infiltration with small numbers of neutrophils and eosinophils, EoE by a prominent eosinophilic infiltrate. Lymphocytic esophagitis (LE), a new entity characterized by peripapillary lymphocytosis, questions the role lymphocytes play in esophageal inflammation. We test the hypothesis that lymphocyte infiltration in RE differs from EoE. One blinded pathologist read esophageal biopsies from 39 RE and 39 EoE patients. Both groups demonstrated significant numbers of lymphocytes (RE 22.7 +/- 2.2/HPF, EoE 19.8 +/- 1.8/HPF). Eosinophils/HPF in RE and EoE were 2.8 +/- 0.7 and 74.9 +/- 8.2, respectively (P < 0.001). Neutrophils were uncommon in RE (0.26 +/- 0.16/HPF) and EoE (0.09 +/- 0.04; P = 0.07). Eight of the 39 RE specimens had >or=50 lymphocytes in >or=1 HPF. Two were consistent with LE. There was an inverse correlation between numbers of eosinophils and lymphocytes in EoE (R = -0.47; P = 0.002), and no correlation between them in RE (R = 0.18; P = 0.36). The patients with EoE who used antireflux medications had fewer lymphocytes (16.3 +/- 1.3 vs 22.2 +/- 2.3/HPF; P = 0.030) and eosinophils (55.6 +/- 5.2 vs 76.0 +/- 8.7/HPF; P = 0.042) than those who did not. The pathological role of lymphocytes in RE and EoE may be underestimated. Our observation that 5% of the RE specimens meet histopathological criteria for LE potentially blurs the line between these entities. The observation that eosinophil counts are lower in EoE when antireflux meds are used supports the notion that reflux plays a role in the clinical expression of EoE.

Heterotopic gastric mucosa (inlet patch) in a patient with laryngopharyngeal reflux (LPR) and laryngeal carcinoma: a case report and review of literature

The inlet patch is an area of heterotopic gastric mucosa most commonly located in the postcricoid portion of the esophagus at, or just below, the level of the upper esophageal sphincter. Esophageal and supraesophageal symptoms are commonly associated with inlet patch, while esophageal adenocarcinoma rarely complicates it. Laryngeal adenocarcinoma associated with inlet patch is not described in the literature. Herein, we present the first reported case of inlet patch associated with laryngeal carcinoma. A 33-year-old female with long-standing asthma and presumed gastroesophageal reflux developed laryngeal cancer at age 22 years that was treated with concomitant radiation and induction chemotherapy. Subsequently, she had refractory heartburn, dysphagia, and cough. These symptoms continued despite two Nissen fundoplications, glottic web division, and optimal medical management. Upper endoscopy at our institution revealed an upper esophageal stricture and a 1 cm inlet patch. Biopsies showed columnar mucosa (predominantly gastric cardiac/fundic type) consistent with inlet patch, with focal intestinal metaplasia. Subsequent endoscopic mucosal resection of the inlet patch resulted in an amelioration of throat and chest pain, cough, and hoarseness. Dysphagia and regurgitation were improved by serial dilatations of the upper esophageal stricture. This case reveals a number of clinical findings associated with inlet patch--chest pain, dysphagia, cough, and hoarseness--as well as a clinical finding that has not been previously associated with inlet patch: laryngeal cancer. Symptoms refractory to optimal medical management and/or surgical intervention should make the clinician and endoscopist more cognizant of the inlet patch.

Morphometric evaluation of oesophageal wall in patients with nutcracker oesophagus and ineffective oesophageal motility

The pathogenesis of nutcracker oesophagus (NE) and ineffective oesophageal motility (IEM) is unclear. Damage to the enteric nervous system or smooth muscle can cause oesophageal dysmotility. We tested the hypothesis that NE and IEM are associated with abnormal muscular or neural constituents of the oesophageal wall. Oesophageal manometry was performed in patients prior to total gastrectomy for gastric cancer. The oesophageal manometries were categorized as normal (n = 7), NE (n = 13), or IEM (n = 5). Histologic examination of oesophageal tissue obtained during surgery was performed after haematoxylin and eosin (H&E) and trichrome staining. Oesophageal innervation was examined after immunostaining for protein gene product-9.5 (PGP-9.5), choline acetyltransferase (ChAT) and neuronal nitric oxide synthase (nNOS). There were no significant differences in inner circular smooth muscle thickness or degree of fibrosis among the three groups. Severe muscle fibre loss was found in four of five patients with IEM. The density of PGP-9.5-reactive neural structures was not different among the three groups. The density of ChAT immunostaining in the myenteric plexus (MP) was significantly greater in patients with NE (P < 0.05) and the density of nNOS immunostaining in the circular muscle (CM) was significantly greater in IEM patients (P < 0.05). The ChAT/nNOS ratio in both MP and CM was significantly greater in NE patients. NE may result from an imbalance between the excitatory and inhibitory innervation of the oesophagus, because more than normal numbers of ChAT-positive myenteric neurones are seen in NE. Myopathy and/or increased number of nNOS neurones may contribute to the hypocontractile motor activity of IEM.

The effect of sildenafil on segmental oesophageal motility and gastro-oesophageal reflux

BACKGROUND

Sildenafil is an inhibitor of type 5 phosphodiesterase. It relaxes or inhibits contraction of smooth muscle by increasing cellular concentrations of cyclic guanosine monophosphate. Multichannel intraluminal impedance manometry/pH allow the precise evaluation of oesophageal bolus transit and acid/non-acid reflux.

AIM

To investigate the effect of sildenafil on segmental oesophageal motor function and gastro-oesophageal reflux.

METHODS

Eight healthy volunteers underwent multichannel intraluminal impedance manometry baseline, and 15, 30 and 45 min before and after a 50-mg dose of sildenafil successively. The subjects underwent 2-h multichannel intraluminal impedance/pH studies on two separate days after either water or sildenafil ingestion.

RESULTS

Sildenafil decreased the resting lower oesophageal sphincter pressure and prolonged the duration of lower oesophageal sphincter relaxation for the 45 min following its ingestion. At 15 min, distal onset velocity, total bolus transit time, bolus presence time and segmental transit time were delayed in the mid to distal oesophagus. At 30 min, distal onset velocity was restored but bolus presence time and bolus presence time were still delayed in distal smooth muscle segment. At 45 min, total bolus transit time and distal onset velocity were restored but bolus presence time and segmental transit time were delayed more in the transition zone. Sildenafil did not alter the reflux.

CONCLUSION

Sildenafil alters lower oesophageal sphincter function and oesophageal bolus transit, but not induce gastro-oesophageal reflux.

Regional differences in oesophageal motor function

We tested the hypotheses that oesophageal bolus transit and motor function vary regionally, with bolus viscosity and with body position. In healthy volunteers, we measured the bolus head advance time, bolus presence time and bolus transit time in the proximal and distal oesophagus using water and viscous materials. We compared concurrent manometric responses. Bolus head advance time, bolus presence time and bolus transit time were longer in the distal oesophagus during water and viscous swallows in the upright and supine positions. The total bolus head advance time and transit time, measured across the entire oesophageal body, were shorter for water than viscous swallows. The amplitudes of peristaltic pressure waves were lower for viscous swallows, and varied as a function of region. These studies demonstrated true functional differences between the proximal and distal oesophagus using multichannel intraluminal impedance and that the viscosity of the bolus is a determinant of oesophageal function.
