Arterial stiffness mediates the association between age and processing speed at low levels of microvascular function in humans across the adult lifespan.

The function of micro- and macrovessels within the peripheral vasculature has been identified as a target for the investigation of potential cardiovascular-based promoters of cognitive decline. However, little remains known regarding the interaction of the micro- and macrovasculature as it relates to cognitive function, especially in cognitively healthy individuals. Therefore, our purpose was to unravel peripheral factors that contribute to the association between age and processing speed. Ninety-nine individuals (51 men, 48 women) across the adult life span (19-81 yr) were used for analysis. Arterial stiffness was quantified as carotid-femoral pulse-wave velocity (cfPWV) and near-infrared spectroscopy assessed maximal tissue oxygenation (Sto2max) following a period of ischemia. Processing speed was evaluated with Trail Making Test (TMT) Parts A and B. Measures of central (cPP) and peripheral pulse pressure (pPP) were also collected. Moderated mediation analyses were conducted to determine contributions to the age and processing speed relation, and first-order partial correlations were used to assess associations while controlling for the linear effects of age. A P ≤ 0.05 was considered statistically significant. At low levels of Sto2max, there was a significant positive (b = 1.92; P = 0.005) effect of cfPWV on time to completion on TMT part A. In addition, cPP (P = 0.028) and pPP (P = 0.027) remained significantly related to part A when controlling for age. These results suggested that the peripheral microvasculature may be a valuable target for delaying cognitive decline, especially in currently cognitively healthy individuals. Furthermore, we reinforced current evidence that pulse pressure is a key endpoint for trials aimed at preventing or delaying the onset of cognitive decline.NEW & NOTEWORTHY Arterial stiffness partially mediates the association between age and processing speed in the presence of low microvascular function, as demarcated by maximum tissue oxygenation following ischemia. Central and peripheral pulse pressure remained associated with processing speed even after controlling for age. Our findings were derived from a sample that was determined to be cognitively healthy, which highlights the potential for these outcomes to be considered during trials aimed at the prevention of cognitive decline.

Key stakeholders' perspectives: A gap analysis of hospital-acquired pressure injuries.

INTRODUCTION: Hospital-acquired pressure injuries (HAPIs) are a global high-stakes patient safety issue. Key stakeholder perspectives regarding their role and experiences with pressure injuries is critical as part of the solution to minimizing HAPI occurrence and attain sustainability. DESIGN: A qualitative, descriptive approach provided multiple perspectives of key stakeholders to support the complexity of HAPI care. The qualitative data are a part of a mixed method convergent research study examining pressure injury prevention and management practices. METHODS: Nursing system theory, mixed method convergent design, and participatory action research methodologies were chosen to address both the gap analysis development and results, achieve collaborative comprehensiveness, and enable key stakeholder involvement throughout this HAPI prevention and management initiative. Participants were recruited and enrolled from a large Level I trauma hospital and the key stakeholders. Demographic information were collected prior to the individual interview. Focused interviews were conducted virtually using zoom technology. Qualitative data were analyzed using NVivo software and thematic analysis was confirmed across the co-investigators for congruence and applicability to the research questions. RESULTS: Qualitative interviews with 26 key stakeholders provided data to support and integrate a link with gap analysis results on the complex health issue of HAPIs. Specific barrier and recommendation themes identified interventions that could be prioritized. The 52 barrier and 52 recommendation themes/sub-theme(s) respectively were organized by Donabedian (structure, process, and outcome) with structure elements the majority. The top three structure barrier themes involved equipment and standards for use, staff prevention education, and specialized health professionals. The top three structure recommendation themes involved specialized health professionals, equipment and standards for use, and an educational plan for those at risk or with HAPIs. CONCLUSION: The article provides findings from the qualitative portion of a mixed method study related to HAPIs. The qualitative findings associated with the gap analysis quantitative results, achieved the goal of the participatory action research key stakeholders' input into HAPI care and can be replicated internationally. CLINICAL RELEVANCE: The benefit of key stakeholder's involvement in solving a clinical problem is sustainability. A quantitative approach and integrating qualitative stakeholders' perspectives provide an in-depth solution that will advance nursing capacity toward health care delivery and HAPI nursing science and policy development on a global level.

Enhanced Skin Assessment Methodology to Detect Early Tissue Damage and Prevent Pressure Injuries.

PURPOSE: The purpose of this study was to evaluate a skin assessment technique, subepidermal moisture (SEM) assessment, to assess, identify, and prevent pressure injuries (PIs) in critically ill adults. DESIGN: This was a retrospective, descriptive, comparative research study. SUBJECTS AND SETTING: The sample comprised 69 critically ill adults; their mean age was 58.8 years (SD 18.1 years). The majority were male (n = 40, 58%), 29 (42%) were African American (AA), and 36 (52%) were White. The study setting was a surgical trauma intensive care unit (STICU) in a southern US Gulf Coast academic level I trauma hospital. Data were collected from September to November 2021. METHODS: We conducted a retrospective medical record review of subjects who had undergone SEM assessment. We also collected demographic and pertinent clinical information, including Braden Scale cumulative scores and subscale scores, documented PI prevention interventions, and PI occurrence and characteristics if developed within 7 days of SEM measurement. We also evaluated whether PI prevention interventions were appropriate. To examine nurse perception of the SEM device, we conducted a web-based survey of nurses providing care in our facility's STICU. Comparison of responses was done using Fisher's test or Chi-square test, and the mean responses from groups were compared using t test. RESULTS: Thirty-five (57%) subjects had a sacral SEM delta ≥0.6; 14 (40%) were AA; 20 (57%) were White; and 11 (31%) had a hospital-acquired PI (HAPI) or present-on-admission (POA) PI. Among the 14 HAPI and POA PI subjects with sacral SEM delta, 11 (79%) had sacral SEM delta ≥0.6. Among 26 AA subjects with sacral SEM delta, 5 had a HAPI or POA PI, and of those, 4 (80%) had sacral SEM delta ≥0.6. A significant and negative correlation was observed between cumulative Braden Scale scores on day 2 and sacral SEM delta (r = -0.28, P = .03) and R heel delta (r = -0.29, P = .03) scores, indicating higher PI risk. Of the 35 patients with a sacral SEM delta ≥0.6, 24 (69%) subjects did not have appropriate PI prevention interventions. Nurses (n = 13) indicated that the SEM device was easy to use and helped them perform an accurate skin assessment on patients with darker skin tones. CONCLUSIONS: This study demonstrates that SEM technology is beneficial to address racial disparities in skin assessment, enhance skin assessment accuracy beyond existing PI care, improve the accuracy of risk assessment, and promote appropriate location-specific PI prevention interventions.

Congenital granular cell epulis: 24 new cases with more differences than similarities to granular cell tumor.

Congenital granular cell epulis (CGCE) is a rare tumor of gingiva that is exclusive to newborns, has marked female predominance, and is rarely associated with other abnormalities. Although benign in behavior, CGCE can be lethal by obstruction of respiration and/or deglutition and can require a multidisciplinary team of specialist at birth for survival of an otherwise normal infant. Histologically, CGCE resembles granular cell tumor (GCT), but unlike GCT, which is Schwannian-derived, derivation of CGCE remains an enigma, largely because of its low prevalence. This study presents 24 new cases of CGCE, the largest series since the original description 150 years ago and permits detailed study of homogeneity of cases diagnosed as CGCE as well as detailed comparisons of CGCE with GCT by clinical, morphological, immunohistochemical, and ultrastructural studies. The data show homogeneity within the CGCE cases, more differences than similarities between CGCE and GCT, and no immunohistochemical staining for common placental proteins/hormones in CGCE. The findings support a primitive mesenchymal cell origin, and a progressive degenerative process in CGCE, rather than neoplasia. Prenatal detection of this lesion is important to facilitate adequate preparations for support of these infants during labor and delivery.

Ostomy Complications and Quality of Life of Ostomy Support Belt/Garment Wearers: A Web-Based Survey.

PURPOSE: The purpose of this study was to examine ostomy complications and health-related quality of life (QOL) in individuals with an ostomy who wear an ostomy support belt/garment. DESIGN: A mixed-methods descriptive study. SUBJECTS AND SETTING: Two hundred two community-living adults with an ostomy were recruited using an industry distribution list. The target sample had no geographic restrictions. METHODS: Descriptive analysis was conducted for all outcomes. Participants were separated into groups depending on type of ostomy belt or belt/garment worn or none. All categorical data were summarized using percentages and numerical data using mean ± standard deviation. Association between categorical factors was evaluated using a χ2 test and proportions of occurrences from 2 groups were compared using a 2-proportion z-test. The mean outcomes for 2 or more groups were compared using t tests or analysis of variance (ANOVA), respectively. If ANOVA showed difference among groups, post hoc analysis of group means was conducted using Tukey's Honestly Significant Difference (HSD) test. RESULTS: Two hundred two respondents completed the survey. Of the 174 participants who responded to the survey question on leakage, 157 (90%) reported experiencing leakage and 135 (77.59%) reported rash or skin irritation. Comparison of whether participants had ever experienced a leakage event was not significantly different across groups (P = .3663). Those who wore an ostomy support belt/garment reported leakage less often (less than once a month) versus respondents who wore other types of belts or no belt (n = 49, 73.13% vs n = 53, 59.55%; P = .0388). Of the 174 participants who responded to the peristomal skin question, 135 (77.59%) participants reported peristomal skin complications. Significantly fewer participants who wore an ostomy support belt/garment reported having peristomal skin irritation compared to those who wore other types of belts or no belt (69.01% vs 84.16%; P = .0080). The mean cumulative total City of Hope Quality of Life (COH QOL) Ostomy score for all participants was 6.45 ± 1.36 out of 10, with the psychosocial domain scoring the lowest at 5.67 ± 1.30 out of 10. No significant differences were observed in mean QOL domain and total scores by those who wore an ostomy support belt/garment, other type of belt/garment, and none. When comparing COH QOL mean scores and leakage frequency of more/less once a month, those who reported leakage more often had significantly worse QOL scores in all 4 domains as well as total scores: physical (P = .0008), psychological (P = .0154), social (P = .0056), spiritual (P = .0376), and total COH QOL score (P = .0018). CONCLUSION: This study provides important information related to ostomy complications and QOL associated with wearing an ostomy belt or belt/garment. The use of an ostomy support belt/garment may offer an additional intervention to decrease frequency of leakage and peristomal skin irritation and improve QOL.

Pressure Injury Prevention and Management: A Gap Analysis Using Key Stakeholder Engagement.

PURPOSE: The purpose of this study was to examine pressure injury prevention and management (PIPM) practices in an academic acute care setting. Specific aims were to (1) develop and examine key stakeholder engagement regarding PIPM practices, (2) develop a valid/reliable gap analysis instrument, and (3) conduct a gap analysis of current PIPM practices. DESIGN: Mixed-methods convergent design and participatory action research. SUBJECTS AND SETTING: A nurse-led council (Council) of key stakeholders from a large academic university healthcare setting was developed. The gap analysis was conducted in a southern gulf coast level I trauma academic acute care hospital in the Southeastern United States. METHODS: A multidisciplinary key stakeholder Council with 27 members was developed to accomplish study aims using the participatory action research approach to train, promote, and foster key stakeholder engagement in all aspects of the research process. The Pressure Injury Prevention Gap Analysis Instrument (PIPGAI) was developed and psychometrically tested. A gap analysis of PIPM practices across a level I trauma academic acute care hospital was conducted using the PIPGAI. RESULTS: The PIPGAI was developed using 2019 Pressure Ulcer/Injury Clinical Practice Guideline recommendations, an integrative literature review/appraisal, a concept map, and Council input. The overall PIPGAI content validity index of 0.95 demonstrated excellent content validity. The individual item content validity index scores ranged from 0.62 to1.0. Low-scoring items (0.62-0.75) were deleted or revised. Interrater reliability was demonstrated by percentage of agreement (62%-79%). Using a modified Delphi approach, items of disagreement were summarized and discussed until 100% consensus was achieved. A gap analysis of PIPM practices was conducted resulting in a cumulative score of 267/553 (48%), indicating gaps in PIPM practices. Fifty (73%) items had content present; 37 of 58 (64%) items had minimal detail, and 36 of 58 (62%) items were difficult or required notable effort to accomplish. Fifty items (63%) had a total score of 4 or less and were identified as a gap (range: 0-7). CONCLUSIONS: The main outcome of this study was an innovative and evidence-based gap analysis process. The study provides (1) a model for key stakeholder engagement, (2) a valid/reliable gap analysis instrument, and (3) a method to evaluate PIPM practices.

Efficacy and Safety of Full-thickness Resection Device (FTRD) for Colorectal Lesions Endoscopic Full-thickness Resection: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: Endoscopic full-thickness resection (eFTR) is a field of increasing interest that offers a minimally invasive resection modality for lesions that are not amenable for resection by conventional methods. Full-thickness resection device (FTRD) is a new device that was developed for a single-step eFTR using an over-the scope-clip. In this meta-analysis, we aim to assess the efficacy and safety of FTRD for eFTR of colorectal lesions. METHODS: A Comprehensive literature review of different databases to identify studies reporting FTRD with outcomes of interest was performed. Studies with <10 cases were excluded. Rates of histologic complete resection (R0), technical success, and complications were extracted. Efficacy was assessed by using the technical and the R0 rates whereas safety was assessed by using the complications rates. Weighted pooled rates (WPRs) and the 95% confidence interval (CI) were calculated depending on the heterogeneity (I2 statistics). RESULTS: Nine studies including 551 patients with 555 lesions were included in this study. The WPR for overall R0 was 82.4% (95% CI: 79.0%-85.5%),with moderate heterogeneity (I2=34.8%). The WPR rate for technical success was 89.25% (95% CI: 86.4%-91.7%), with low heterogeneity (I2=23.7%). The WPR for total complications rate was 10.2% (7.8, 12.8%) with no heterogeneity. The pooled rate for minor bleeding, major bleeding, postpolypectomy syndrome, and perforation were 3.2%, 0.97%, 2.2%, and 1.2%, respectively. Of 44 periappendicular lesions, the pooled rate for acute appendicitis was 19.7%. CONCLUSIONS: FTRD seems to be effective and safe for eFTR of difficult colorectal lesions. Large prospective studies comparing FTRD with conventional resection techniques are warranted.

Nurse's Achilles Heel: Using Big Data to Determine Workload Factors That Impact Near Misses.

PURPOSE: To explore how big data can be used to identify the contribution or influence of six specific workload variables: patient count, medication count, task count call lights, patient sepsis score, and hours worked on the occurrence of a near miss (NM) by individual nurses. DESIGN: A correlational and cross-section research design was used to collect over 82,000 useable data points of historical workload data from the three unique systems on a medical-surgical unit in a midsized hospital in the southeast United States over a 60-day period. Data were collected prior to the start of the Covid-19 pandemic in the United States. METHODS: Combined data were analyzed using JMP Pro version 12. Mean responses from two groups were compared using a t-test and those from more than two groups using analysis of variance. Logistic regression was used to determine the significance of impact each workload variable had on individual nurses' ability to administer medications successfully as measured by occurrence of NMs. FINDINGS: The mean outcome of each of the six workload factors measured differed significantly (p < .0001) among nurses. The mean outcome for all workload factors except the hours worked was found to be significantly higher (p < .0001) for those who committed an NM compared to those who did not. At least one workload variable was observed to be significantly associated (p < .05) with the occurrence or nonoccurrence of NMs in 82.6% of the nurses in the study. CONCLUSIONS: For the majority of the nurses in our study, the occurrence of an NM was significantly impacted by at least one workload variable. Because the specific variables that impact performance are different for each individual nurse, decreasing only one variable, such as patient load, will not adequately address the risk for NMs. Other variables not studied here, such as education and experience, might be associated with the occurrence of NMs. CLINICAL RELEVANCE: In the majority of nurses, different workload variables increase their risk for an NM, suggesting that interventions addressing medication errors should be implemented based on the individual's risk profile.

Enhanced Mitochondrial DNA Repair Resuscitates Transplantable Lungs Donated After Circulatory Death.

BACKGROUND: Transplantation of lungs procured after donation after circulatory death (DCD) is challenging because postmortem metabolic degradation may engender susceptibility to ischemia-reperfusion (IR) injury. Because oxidative mitochondrial DNA (mtDNA) damage has been linked to endothelial barrier disruption in other models of IR injury, here we used a fusion protein construct targeting the DNA repair 8-oxoguanine DNA glycosylase-1 (OGG1) to mitochondria (mtOGG1) to determine if enhanced repair of mtDNA damage attenuates endothelial barrier dysfunction after IR injury in a rat model of lung procurement after DCD. MATERIALS AND METHODS: Lungs excised from donor rats 1 h after cardiac death were cold stored for 2 h after which they were perfused ex vivo in the absence and presence of mt-OGG1 or an inactive mt-OGG1 mutant. Lung endothelial barrier function and mtDNA integrity were determined during and at the end of perfusion, respectively. RESULTS AND CONCLUSIONS: Mitochondria-targeted OGG1 attenuated indices of lung endothelial dysfunction incurred after a 1h post-mortem period. Oxidative lung tissue mtDNA damage as well as accumulation of proinflammatory mtDNA fragments in lung perfusate, but not nuclear DNA fragments, also were reduced by mitochondria-targeted OGG1. A repair-deficient mt-OGG1 mutant failed to protect lungs from the adverse effects of DCD procurement. CONCLUSIONS: These findings suggest that endothelial barrier dysfunction in lungs procured after DCD is driven by mtDNA damage and point to strategies to enhance mtDNA repair in concert with EVLP as a means of alleviating DCD-related lung IR injury.

Deficiency of tumor suppressor Merlin facilitates metabolic adaptation by co-operative engagement of SMAD-Hippo signaling in breast cancer.

The NF2 gene encodes the tumor and metastasis suppressor protein Merlin. Merlin exerts its tumor suppressive role by inhibiting proliferation and inducing contact-growth inhibition and apoptosis. In the current investigation, we determined that loss of Merlin in breast cancer tissues is concordant with the loss of the inhibitory SMAD, SMAD7, of the TGF-ß pathway. This was reflected as dysregulated activation of TGF-ß signaling that co-operatively engaged with effectors of the Hippo pathway (YAP/TAZ/TEAD). As a consequence, the loss of Merlin in breast cancer resulted in a significant metabolic and bioenergetic adaptation of cells characterized by increased aerobic glycolysis and decreased oxygen consumption. Mechanistically, we determined that the co-operative activity of the Hippo and TGF-ß transcription effectors caused upregulation of the long non-coding RNA Urothelial Cancer-Associated 1 (UCA1) that disengaged Merlin's check on STAT3 activity. The consequent upregulation of Hexokinase 2 (HK2) enabled a metabolic shift towards aerobic glycolysis. In fact, Merlin deficiency engendered cellular dependence on this metabolic adaptation, endorsing a critical role for Merlin in regulating cellular metabolism. This is the first report of Merlin functioning as a molecular restraint on cellular metabolism. Thus, breast cancer patients whose tumors demonstrate concordant loss of Merlin and SMAD7 may benefit from an approach of incorporating STAT3 inhibitors.

The Family Meal Challenge: A Faith-Based Intervention to Empower Families.

African Americans have increased rates of overweight and obesity and are least likely to participate in family meals compared with other racial groups. A Family Meal Challenge (FMC) was developed with the objective of empowering individuals to eat healthy meals together as a family. The FMC was presented through four classes in three churches, two faith-based ministries, and two community service programs in health disparity zip codes. Surveys (N = 257) indicated a positive response. Engaging participants and teaching the benefits of eating healthy family meals in a faith-based environment are feasible and may increase the frequency of family meals. Information is provided to create and implement an FMC in any faith setting.

Pediatric obesity screening and prevention strategies.

Childhood overweight and obesity is a major health concern in the United States. It is recommended that every well-child examination include body mass index measurements and obesity prevention discussions that encourage healthy eating habits, regular physical exercise, and limited television and computer screen time. Providers can make a difference through strategic intervention.

Women's perceptions of body mass graphics and their preferences for weight counselling.

Health care providers may lack data-driven guidance about best practises for discussing weight. We assessed women's self-perception of body mass index (BMI) and preferences for weight counselling by provider characteristics and the initiating question. A voluntary, anonymous survey was completed by 756 women (age ≥ 19 year) at our tertiary care obstetrics and gynaecology clinics in autumn 2021. The respondents' height and weight were collected before respondents selected graphics from a validated Body Image Scale that they felt best represented their current body size and which graphs should prompt weight loss or gain recommendations. Respondents were asked their preferences about provider characteristics for discussion about weight and to identify which of six initiating questions from a provider was most and least preferred. Blank responses were allowed. In 708 responses, 366 women (52%) selected the most accurate graphic that corresponded to their BMI; the selected graphic represented a lower than actual BMI in 268 women (38%) and higher in 74 women (10%). In 648 responses, 374 women (58%) preferred a female provider, but provider body shape, ethnicity/race and age were not important to most women. The most preferred question to initiate a discussion about weight was "A lot of women have trouble achieving or maintaining a healthy weight; is that something we can discuss?" in 181 of 555 women (33%), and the least preferred question was "Do you feel like you are at an appropriate weight?" in 172 of 554 women (31%). Provider knowledge about patient preferences regarding questions may facilitate the discussion about weight.

Amyloid-ß and caspase-1 are indicators of sepsis and organ injury.

Background: Sepsis is a life-threatening condition that results from a dysregulated host response to infection, leading to organ dysfunction. Despite the prevalence and associated socioeconomic costs, treatment of sepsis remains limited to antibiotics and supportive care, and a majority of intensive care unit (ICU) survivors develop long-term cognitive complications post-discharge. The present study identifies a novel regulatory relationship between amyloid-ß (Aß) and the inflammasome-caspase-1 axis as key innate immune mediators that define sepsis outcomes. Methods: Medical ICU patients and healthy individuals were consented for blood and clinical data collection. Plasma cytokine, caspase-1 and Aß levels were measured. Data were compared against indices of multiorgan injury and other clinical parameters. Additionally, recombinant proteins were tested in vitro to examine the effect of caspase-1 on a functional hallmark of Aß, namely aggregation. Results: Plasma caspase-1 levels displayed the best predictive value in discriminating ICU patients with sepsis from non-infected ICU patients (area under the receiver operating characteristic curve=0.7080). Plasma caspase-1 and the Aß isoform Aßx-40 showed a significant positive correlation and Aßx-40 associated with organ injury. Additionally, Aß plasma levels continued to rise from time of ICU admission to 7 days post-admission. In silico, Aß harbours a predicted caspase-1 cleavage site, and in vitro studies demonstrated that caspase-1 cleaved Aß to inhibit its auto-aggregation, suggesting a novel regulatory relationship. Conclusions: Aßx-40 and caspase-1 are potentially useful early indicators of sepsis and its attendant organ injury. Additionally, Aßx-40 has emerged as a potential culprit in the ensuing development of post-ICU syndrome.

Effectiveness of simulation-based orientation of baccalaureate nursing students preparing for their first clinical experience.

This study evaluated the effectiveness of a 2-day, simulation-based orientation for baccalaureate nursing students preparing to begin their first clinical experience. Students were recruited for participation in the study from a clinical foundation course. Actors (standardized patients) provided students with the chance to engage with simulated real patients in realistic clinical situations prior to entering the clinical setting. Students' perceived stress, knowledge acquisition, anxiety, self-confidence, and satisfaction with the orientation process were assessed. Findings indicated a statistically significant increase in knowledge of and confidence in skills needed when first entering the clinical setting and a decrease in anxiety following the orientation activity. Students had a positive attitude about interaction with real patients, faculty, and other students during the experience. Improved self-confidence and satisfaction were reported as a result of participation in simulation-based orientation.

Transforming Care at the Bedside (TCAB): enhancing direct care and value-added care.

AIM: The purpose of this study was to examine the effectiveness of a Transforming Care at the Bedside initiative from a unit perspective. BACKGROUND: Improving patient outcomes and nurses' work environments are the goals of Transforming Care at the Bedside. Transforming Care at the Bedside creates programs of change originating at the point of care and directly promoting engagement of nurses to transform work processes and quality of care on medical-surgical units. METHODS: This descriptive comparative study draws on multiple data sources from two nursing units: a Transforming Care at the Bedside unit where staff tested, adopted and implemented improvement ideas, and a control unit where staff continued traditional practices. Change theory provided the framework for the study. RESULTS: Direct care and value-added care increased on Transforming Care at the Bedside unit compared with the control unit. Transforming Care at the Bedside unit decreased in incidental overtime. Nurses reported that the process challenged old ways of thinking and increased nursing innovations. Hourly rounding, bedside reporting and the use of pain boards were seen as positive innovations. CONCLUSIONS: Evidence supported the value-added dimension of the Transforming Care at the Bedside process at the unit level. IMPLICATIONS FOR NURSING MANAGEMENT: Nurses recognized the significance of their input into processes of change. Transformational leadership and frontline projects provide a vehicle for innovation through application of human capital.

A Quality Improvement Project: Implementation of the Centers for Disease Control and Prevention's Hepatitis C Virus Treatment Guidelines at an Addiction Treatment Center.

PURPOSE: This quality improvement project was introduced at an addiction treatment center to implement the Centers for Disease Control and Prevention's (CDC's) hepatitis C virus (HCV) treatment guidelines and offer anticraving medications to patients to improve standards of care of patients with substance use disorders. LITERATURE REVIEW: Patients with opioid use disorders are at the highest risk of contracting HCV. More than 80% of people in the United States with opioid use disorders who use intravenous drugs have contracted HCV. Despite the high prevalence of HCV, patients at treatment centers are being screened only for HCV antibodies (HCV-AB) and are not receiving the CDC's HCV treatment guidelines. The CDC has treatment recommendations of hepatitis panels, full STD testing, and early follow-up care. METHOD: This quality improvement project utilized the Plan-Do-Study-Act tool. With the application of Plan-Do-Study-Act, for patients identified with HCV-AB, the established CDC HCV treatment guidelines were followed, and the clinical progress of the implementation of the guidelines was monitored. Chart reviews comparing compliance of guidelines before and after the study were implemented. PARTICIPANTS: A convenience sample of 125 patients were collected, and of these, 32 patients were found to be HCV-AB+. FINDINGS: The findings revealed that 18.75% of patients followed the CDC's HCV recommendations after the quality improvement project compared with 6.25% of patients before the intervention. The number of HIV testing offered increased by 40.00% as a result of the implementation of the project.

Impact of Weight on Severity of Hospital Course in Children Admitted With COVID-19.

Objective. To describe the impact of weight on length of stay (LOS) and oxygen requirement among hospitalized children with COVID-19. Methods. This is a retrospective review of 153 children admitted for COVID-19 from March 2020 to October 2021. Body mass index (BMI) percentile and weight-for-age (WFA) percentile were used to determine weight status for children ≥2 years and <2 years respectively. Results. We found 2 distinct patterns for patients <2 years and ≥2 years; The likelihood of needing oxygen and LOS ≥ 5 days was higher for children ≥2 years with BMI ≥ 85th percentile (P = .0415 and P = .0197). Among those <2 years, mean WFA percentile decreased with increasing oxygen need (P = .0325). There was a negative correlation between LOS and WFA percentile (r = -.31, P = .0123). Conclusion. It is important to stratify patients' risk according to their age, BMI and WFA percentile during hospitalization for COVID 19.

Effect of Bariatric Surgery on Plasma Cell-Free Mitochondrial DNA, Insulin Sensitivity and Metabolic Changes in Obese Patients.

While improvement of mitochondrial function after bariatric surgery has been demonstrated, there is limited evidence about the effects of bariatric surgery on circulatory cell-free (cf) mitochondrial DNA (mtDNA) and intracellular mtDNA abundance. Plasma and peripheral blood mononuclear (PBM) cells were isolated from healthy controls (HC) and bariatric surgery patients before surgery and 2 weeks, 3 months, and 6 months after surgery. At baseline, the plasma level of short cf-mtDNA (ND6, ~100 bp) fragments was significantly higher in obese patients compared to HC. But there was no significant variation in mean ND6 values post-surgery. A significant positive correlation was observed between preop plasma ND6 levels and HgbA1c, ND6 and HOMA-IR 2 weeks post-surgery, and mtDNA content 6 months post-surgery. Interestingly, plasma from both HC and obese groups at all time points post-surgery contains long (~8 kb) cf-mtDNA fragments, suggesting the presence of near-intact and/or whole mitochondrial genomes. No significant variation was observed in mtDNA content post-surgery compared to baseline data in both PBM and skeletal muscle samples. Overall, bariatric surgery improved insulin sensitivity and other metabolic parameters without significant changes in plasma short cf-mtDNA levels or cellular mtDNA content. Our study provides novel insights about possible molecular mechanisms underlying the metabolic effects of bariatric surgery and suggests the development of new generalized approaches to characterize cf-mtDNA.

The adherence to the American Association for the Study of Liver Diseases 2018 guidelines in the management of hepatocellular carcinoma and its impact on survival.

Introduction: In two Korean and Italian studies, the adherence rate (AR) to ASSLD 2005 guidelines in the management of hepatocellular carcinoma (HCC) was 60%. In a US study, the AR to American Association for the Study of Liver Disease (AASLD) 2005 guidelines was 73.3%, 26.8%, 25.3%, and 58.8% for patients with Barcelona Clinic Liver Cancer (BCLC) Stage A, B, C, and D, respectively, and nonadherence to guidelines was associated with longer overall survival (OS) in patients with BCLC Stage D. Here, we explored the AR to AASLD 2018 guidelines and its impact on OS. Methods: Between 2017 and 2019, 148 unique treatment-naïve patients with HCC were identified. Patients were staged according to the BCLC staging system and their AR to AASLD 2018 guidelines was noted. OS was estimated using Kaplan-Meier method. Survivals among patients from different groups was compared using Log-rank test. Results: The overall AR to AASLD 2018 guidelines was 83%. The AR for BCLC Stages 0, A, B, C, and D were 100%, 97%, 77%, 77%, and 38%, respectively. In patients with BCLC Stage D, the OS of patients treated with modalities adherent versus nonadherent to AASLD 2018 guidelines was 0.03 vs. 5.2 months (P = 0.0005). Otherwise, adherence versus nonadherence to AASLD 2018 guidelines showed no statistically significant differences in OS for patients with BCLC Stages 0, A, B, and C. Conclusion: The overall AR to AASLD 2018 guidelines was 83%. Nonadherence to AASLD 2018 guidelines in patients with BCLC Stage D translated into better OS.
