Culpability Framing Influences on Community Support for Those Managing Illness: A Multi-Malady Comparison of Mediated Health Stigma.

Prior research demonstrates an influence of culpability framing on news consumers' perceptions about, and willingness to provide support for, those managing illness. Framing research of this sort has typically focused on the effect of frames on a particular health context (e.g. cancer). It is necessary to examine how three health frames which are overwhelmingly represented in health news could be uniquely influencing perceptions about those managing illness in a number of disparate health contexts. Specifically, we explore the nature of health frame influence as it relates to news reports regarding alcoholism, morbid obesity, and cancer. These illnesses represent the three of the most prominent health concerns for Americans that also vary in terms of how they relate to four chief cues for stigma communication. Experimental findings reveal unique ways in which culpability framing influences social support dispositions for those managing illness, as a function of intergroup anxiety perceptions.

A Medicaid-Funded Statewide Diabetes Quality Improvement Collaborative: Ohio 2020‒2022.

We used a collective impact model to form a statewide diabetes quality improvement collaborative to improve diabetes outcomes and advance diabetes health equity. Between 2020 and 2022, in collaboration with the Ohio Department of Medicaid, Medicaid Managed Care Plans, and Ohio's seven medical schools, we recruited 20 primary care practices across the state. The percentage of patients with hemoglobin A1c greater than 9% improved from 25% to 20% over two years. Applying our model more broadly could accelerate improvement in diabetes outcomes.

Exploring the factors affecting home dialysis patients' participation in telehealth-assisted home visits: A mixed-methods study.

BACKGROUND: Technology, such as telehealth, is increasingly used to support home dialysis patients. The challenges patients and carers face when home dialysis nursing visits are provided via telehealth have yet to be explored. OBJECTIVES: To explore patients' and carers' perspectives as they transition to telehealth-assisted home visits and identify the factors influencing their engagement in this modality. DESIGN: A mixed-methods approach, guideed by the behaviour change wheel using the capability, opportunity, motivation-behaviour model to explore individual's perceptions of telehealth. PARTCIPANTS: Home dialysis patients and their carers. MEASURUEMENTS: Suveys and qualitative interviews. METHODS: A mixed-methods approach was undertaken, combining surveys and qualitative interviews. It was guided by the Behaviour Change Wheel using the Capability, Opportunity, Motivation- Behaviour model to explore individuals' perceptions of telehealth. RESULTS: Thirty-four surveys and 21 interviews were completed. Of 34 survey participants, 24 (70%) preferred face-to-face home visits and 23 (68%) had previously engaged in telehealth. The main perceived barrier identified in the surveys was knowledge of telehealth, but participants believed there were opportunities for them to use telehealth. Interview results revealed that the convenience and flexibility of telehealth were perceived as the main advantages of telehealth. However, challenges such as the ability to conduct virtual assessments and to communicate effectively between clinicians and patients were identified. Patients from non-English speaking backgrounds and those with disabilities were particularly vulnerable because of the many barriers they faced. These challenges may further entrench the negative view regarding technology, as discussed by interview participants. CONCLUSION: This study suggested that a blended model combining telehealth and face-to-face services would allow patient choice and is important to facilitate equity of care, particularly for those patients who were unwilling or had difficulty adopting technology.

Quality of Care Program Reduces Unplanned Health Care Utilization in Patients With Inflammatory Bowel Disease.

INTRODUCTION: There is significant variation in processes and outcomes of care for patients with inflammatory bowel disease (IBD), suggesting opportunities to improve quality of care. We aimed to determine whether a structured quality of care program can improve IBD outcomes, including the need for unplanned health care utilization. METHODS: We used a structured approach to improve adult IBD care in 27 community-based gastroenterology practices and academic medical centers. Patient-reported outcomes (PRO) and health care utilization were collected at clinical visits. Outcomes were monitored monthly using statistical process control charts; improvement was defined by special cause (nonrandom) variation over time. Multivariable logistic regression was applied to patient-level data. Nineteen process changes were offered to improve unplanned health care utilization. Ten outcomes were assessed, including disease activity, remission status, urgent care need, recent emergency department use, hospitalizations, computed tomography scans, health confidence, corticosteroid or opioid use, and clinic phone calls. RESULTS: We collected data prospectively from 20,382 discrete IBD visits. During the 15-month project period, improvement was noted across multiple measures, including need for urgent care, hospitalization, steroid use, and opioid utilization. Adjusted multivariable modeling showed significant improvements over time across multiple outcomes including urgent care need, health confidence, emergency department utilization, hospitalization, corticosteroid use, and opioid use. Attendance at monthly coached webinars was associated with improvement. DISCUSSION: Outcomes of IBD care were improved using a structured quality improvement program that facilitates small process changes, sharing of best practices, and ongoing feedback. Spread of these interventions may facilitate broad improvement in IBD care when applied to a large population.

Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD): A feasibility study.

BACKGROUND: There is substantial variation in peritonitis rates across peritoneal dialysis (PD) units globally. This may, in part, be related to the wide variability in the content and delivery of training for PD nurse trainers and patients. AIM: The aim of this study was to test the feasibility of implementing the Targeted Education ApproaCH to improve Peritoneal Dialysis Outcomes (TEACH-PD) curriculum in real clinical practice settings. METHODS: This study used mixed methods including questionnaires and semi-structured interviews (pretraining and post-training) with nurse trainers and patients to test the acceptability and usability of the PD training modules implemented in two PD units over 6 months. Quantitative data from the questionnaires were analysed descriptively. Interviews were analysed using thematic analysis. RESULTS: Ten PD trainers and 14 incident PD patients were included. Mean training duration to complete the modules were 10.9 h (range 6-17) and 24.9 h (range 15-35), for PD trainers and patients, respectively. None of the PD patients experienced PD-related complications at 30 days follow-up. Three (21%) patients were transferred to haemodialysis due to non-PD-related complications. Ten trainers and 14 PD patients participated in the interviews. Four themes were identified including use of adult learning principles (trainers), comprehension of online modules (trainers), time to complete the modules (trainers) and patient usability of the manuals (patient). CONCLUSION: This TEACH-PD study has demonstrated feasibility of implementation in a real clinical setting. The outcomes of this study have informed refinement of the TEACH-PD modules prior to rigorous evaluation of its efficacy and cost-effectiveness in a large-scale study.

Advance Care Planning and End-of-Life Issues in Head and Neck Cancer.

Advance Care Planning and End of Life discussions are critical in all cancers but are often overlooked or delayed. Head and Neck Cancer patients have the added stigma of visible morbidity and negative quality of life issues. We present a case example and discussion of these issues in the Head and Neck cancer clinic.

Effect of Increased Blood Flow Rate on Hemodialysis Tolerability and Achieved Urea Reduction Ratio.

Long-term hemodialysis (HD) imposes a significant burden on the quality of life of end-stage kidney disease patients. Optimizing dialysis dose is an important consideration in this population; however, evidence exists that suggests that attainment of population dialysis targets is associated with increased intradialytic complications. In this prospective, before-after study, the blood flow rate (BFR) of 63 maintenance HD patients was increased by 100 mL/min to a maximum BFR of 400 mL/min to determine the impact on patient tolerability and urea reduction ratio (URR) of an increased BFR. Tolerability was assessed by time to recovery (TTR) after dialysis, a validated measure of patient tolerability, and intradialytic complications. Median pre-increase BFR was 252 mL/min compared to 349 mL/min post-increase. Mean TTR decreased from 4.67 h to 4.03 h (P = 0.688). No association was observed between percentage change in BFR (R2 = 0.0) or post-increase BFR (R2 = 0.0) and absolute change in TTR. A significant, positive association was observed between both the absolute and relative changes to BFR and the achieved URR. We found no evidence that increasing BFR by 100 mL/min diminishes patient tolerability.

Bronchodilator responsiveness assessed by forced oscillometry and multiple breath washout techniques in preschool children.

IMPORTANCE: The forced oscillation (FOT) and multiple breath washout (MBW) techniques are passive tests of lung function, and are reliable for preschool-age children. There has not been comparison testing to determine which test could more accurately differentiate between healthy controls and poorly controlled asthmatics, or differentiate a response to bronchodilator administration. OBJECTIVE: To determine whether the MBW and/or FOT could differentiate between healthy controls and poorly controlled asthmatics, and whether the two tests could detect a response to bronchodilator administration. METHODS: Twenty-eight healthy controls and 23 poorly controlled asthmatics 3-6 years of age participated. All subjects were administered the MBW followed by the FOT. A bronchodilator was then administered and testing was repeated. Wilcoxon Rank Sum tests were used to compare the difference between healthy controls and poorly controlled asthmatics. Wilcoxon Signed Rank tests were used to compare the pre- and post-bronchodilator values. RESULTS: Neither MBW nor FOT differentiated healthy controls from poorly controlled asthmatics (pre-bronchodilator data); both groups had similar baseline gas mixing and airway mechanics. There was no improvement in any MBW outcomes post-bronchodilator administration. FOT detected a significant and similar degree of improvement in the airway mechanics in both groups. INTERPRETATION: Neither MBW nor FOT differentiated between poorly controlled asthmatics (when well) and healthy controls. MBW did not detect a significant bronchodilator response in either subject group, whereas FOT detected a similar degree of bronchodilator responsiveness in both groups. This discrepancy may reflect differential changes in airway mechanics and gas mixing properties in response to bronchodilators.

Pulmonary Alveolar Proteinosis in Association with Secondary Hemophagocytic Lymphohistiocytosis.

Pulmonary alveolar proteinosis (PAP) is a rare diffuse lung disease in the pediatric population. There are currently few cases documenting hemophagocytic lymphohistiocytosis as a cause for secondary PAP. We describe an ex-preterm child with secondary hemophagocytic lymphohistiocytosis, complicated by PAP and hypoxemic respiratory failure.

Genotype-phenotype characterization in 13 individuals with chromosome Xp11.22 duplications.

We report 13 new individuals with duplications in Xp11.22-p11.23. The index family has one male and two female members in three generations with mild-severe intellectual disability (ID), speech delay, dysmorphic features, early puberty, constipation, and/or hand and foot abnormalities. Affected individuals were found to have two small duplications in Xp11.22 at nucleotide position (hg19) 50,112,063-50,456,458 bp (distal) and 53,160,114-53,713,154 bp (proximal). Collectively, these two regions include 14 RefSeq genes, prompting collection of a larger cohort of patients, in an attempt to delineate critical genes associated with the observed phenotype. In total, we have collected data on nine individuals with duplications overlapping the distal duplication region containing SHROOM4 and DGKK and eight individuals overlapping the proximal region including HUWE1. Duplications of HUWE1 have been previously associated with non-syndromic ID. Our data, with previously published reports, suggest that duplications involving SHROOM4 and DGKK may represent a new syndromic X-linked ID critical region associated with mild to severe ID, speech delay +/- dysarthria, attention deficit disorder, precocious puberty, constipation, and motor delay. We frequently observed foot abnormalities, 5th finger clinodactyly, tapering fingers, constipation, and exercise intolerance in patients with duplications of these two genes. Regarding duplications including the proximal region, our observations agree with previous studies, which have found associations with intellectual disability. In addition, expressive language delay, failure to thrive, motor delay, and 5th finger clinodactyly were also frequently observed in patients with the proximal duplication.

Rethinking critical care: decreasing sedation, increasing delirium monitoring, and increasing patient mobility.

BACKGROUND: Sedation management, delirium monitoring, and mobility programs have been addressed in evidence-based critical care guidelines and care bundles, yet implementation in the ICU remains variable. As critically ill patients occupy higher percentages of hospital beds in the United States and beyond, it is increasingly important to determine mechanisms to deliver better care. The Institute for Healthcare Improvement's Rethinking Critical Care (IHI-RCC) program was established to reduce harm of critically ill patients by decreasing sedation, increasing monitoring and management of delirium, and increasing patient mobility. Case studies of a convenience sample of five participating hospitals/health systems chosen in advance of the determination of their clinical outcomes are presented in terms of how they got started and process improvements in sedation management, delirium management, and mobility. METHODS: The IHI-RCC program involved one live case study and five iterations of an in-person seminar in a 33-month period (March 2011-November 2013) that emphasized interdisciplinary teamwork and culture change. RESULTS: Qualitative descriptions of the changes tested at each of the five case study sites demonstrate improvements in teamwork, processes, and reliability of daily work. Improvement in ICU length of stay and length of stay on the ventilator between the pre- and postimplementation periods varied from slight to substantial. CONCLUSION: Changing critical care practices requires an interdisciplinary approach addressing cultural, psychological, and practical issues. The key lessons of the IHI-RCC program are as follows: the importance of testing changes on a small scale, feeding back data regularly and providing sufficient education, and building will through seeing the work in action.

IL-17A induces Pendrin expression and chloride-bicarbonate exchange in human bronchial epithelial cells.

The epithelium plays an active role in the response to inhaled pathogens in part by responding to signals from the immune system. Epithelial responses may include changes in chemokine expression, increased mucin production and antimicrobial peptide secretion, and changes in ion transport. We previously demonstrated that interleukin-17A (IL-17A), which is critical for lung host defense against extracellular bacteria, significantly raised airway surface pH in vitro, a finding that is common to a number of inflammatory diseases. Using microarray analysis of normal human bronchial epithelial (HBE) cells treated with IL-17A, we identified the electroneutral chloride-bicarbonate exchanger Pendrin (SLC26A4) as a potential mediator of this effect. These data were verified by real-time, quantitative PCR that demonstrated a time-dependent increase in Pendrin mRNA expression in HBE cells treated with IL-17A up to 48 h. Using immunoblotting and immunofluorescence, we confirmed that Pendrin protein expression is increased in IL-17 treated HBE cells and that it is primarily localized to the mucosal surface of the cells. Functional studies using live-cell fluorescence to measure intracellular pH demonstrated that IL-17A induced chloride-bicarbonate exchange in HBE cells that was not present in the absence of IL-17A. Furthermore, HBE cells treated with short interfering RNA against Pendrin showed substantially reduced chloride-bicarbonate exchange. These data suggest that Pendrin is part of IL-17A-dependent epithelial changes and that Pendrin may therefore be a therapeutic target in IL-17A-dependent lung disease.

The relationship of bedside nurses' emotional intelligence with quality of care.

Emotional intelligence, a predictor of productivity and success, may impact behaviors responsible for quality of care. This study examined if emotional intelligence of units' bedside nurses is related to the quality of care delivered to the patients. In this study, emotional intelligence was found to be correlated to the number of Clostridium difficile infections, MRSA infections, patient falls with injury, and pressure ulcer screenings (P < .001) in the inpatient acute care setting.

The novel dry extract BNO 1011 stimulates chloride transport and ciliary beat frequency in human respiratory epithelial cultures.

BACKGROUND: Herbal remedies predate written history and continue to be used more frequently than conventional pharmaceutical medications. The novel dry extract BNO 1011 is based on a combination of five herbs that is used to treat acute and chronic rhinosinusitis. We evaluated the pharmacologic effects of the novel dry extract BNO 1011 on human respiratory epithelial cultures specifically addressing electrolyte transport and cilia beat frequency (CBF). METHODS: Well-differentiated human bronchial epithelial cultures grown at an air-liquid interface were treated on the apical or basolateral surface with varying concentrations of dry extract BNO 1011. Changes in transepithelial sodium and chloride transport were determined in Ussing chambers under voltage-clamped conditions. Changes in CBF were determined using the Sissons-Ammons Video Analysis system (Ammons Engineering, Mt. Morris, MI). RESULTS: When applied to the apical surface, dry extract BNO 1011 activated forskolin-stimulated chloride secretion and ciliary beat in a dose-dependent fashion. Basolateral application of dry extract BNO 1011 did not alter the measured physiological properties. CONCLUSION: Apical application of dry extract BNO 1011 stimulates both chloride secretion and CBF and therefore may augment mucociliary clearance.

Characterization of 12 polymorphic microsatellite markers in the liverwort Marchantia inflexa (Marchantiaceae).

PREMISE OF THE STUDY: Microsatellite markers were developed in Marchantia inflexa, a haploid liverwort with unisexual individuals, to identify clonal genotypes and measure population genetic variability. METHODS AND RESULTS: Twelve polymorphic primer sets were developed from three enriched genomic libraries. Primers were fluorescently labeled, and alleles were identified by fragment analysis. These primers were tested in four natural populations and revealed a moderate level of genetic variation within four populations, as indicated by the number of alleles per locus (range = 1-5). CONCLUSIONS: Development of polymorphic markers is crucial to the identification of individuals and will allow additional research into this species, particularly on its population genetics and metapopulation dynamics.

Protecting the Vulnerable: The Importance of Effective Parental Tobacco-Dependence Treatment During Prenatal and Newborn Care.

Tobacco use among pregnant women, as well as second- and third-hand smoke exposure of their infants, translates into the startling fact that more than one third of American children live with at least one parent who smokes cigarettes daily. Maternal smoking or second-hand smoke exposure during pregnancy is deleterious to the mother's health and contributes to prematurity, low birth-weight infants, and increased risk of sudden infant death syndrome (SIDS) and recurrent wheezing during the first year of life. Pregnant women who stop tobacco use during pregnancy are at high risk for postpartum relapse frequently associated with a partner who smokes tobacco, stress, poverty, and lack of social and medical support to remain tobacco free. Enhanced efforts to identify and support pregnant women who smoke, and to implement strategies to prevent exposure of their fetus and newborn to the hazards of tobacco-smoke exposure, are paramount in our public health efforts to eliminate health disparities in the United States. We discuss the critical elements of programs to assist mothers to stop smoking during pregnancy and toward family efforts to maintain a smoke-free environment for their infant. Postpartum interventions, whether in the neonatal intensive care unit (NICU), newborn nursery, or postnatal care setting, can provide assistance that women need to remain smoke free, to educate spouses or significant others and their families, and to aide in establishing goals of maintaining a tobacco smoke-free home and car. Physicians and other perinatal healthcare providers have a duty to identify pregnant women who smoke for "meaningful use" in the electronic medical record, and to provide advice and assistance in evidence-based smoking interventions in obstetrical care settings. Pediatricians, neonatologists, and others providing postpartum, "normal" nursery or NICU care have an opportunity to protect infants and young children from second- and third-hand smoke exposure by assisting their parents and family members in maintaining a tobacco-free environment to improve the health of infants, toddlers, and young children.

Mechanics of lipid bilayer junctions affecting the size of a connecting lipid nanotube.

In this study we report a physical analysis of the membrane mechanics affecting the size of the highly curved region of a lipid nanotube (LNT) that is either connected between a lipid bilayer vesicle and the tip of a glass microinjection pipette (tube-only) or between a lipid bilayer vesicle and a vesicle that is attached to the tip of a glass microinjection pipette (two-vesicle). For the tube-only configuration (TOC), a micropipette is used to pull a LNT into the interior of a surface-immobilized vesicle, where the length of the tube L is determined by the distance of the micropipette to the vesicle wall. For the two-vesicle configuration (TVC), a small vesicle is inflated at the tip of the micropipette tip and the length of the tube L is in this case determined by the distance between the two interconnected vesicles. An electrochemical method monitoring diffusion of electroactive molecules through the nanotube has been used to determine the radius of the nanotube R as a function of nanotube length L for the two configurations. The data show that the LNT connected in the TVC constricts to a smaller radius in comparison to the tube-only mode and that tube radius shrinks at shorter tube lengths. To explain these electrochemical data, we developed a theoretical model taking into account the free energy of the membrane regions of the vesicles, the LNT and the high curvature junctions. In particular, this model allows us to estimate the surface tension coefficients from R(L) measurements.

Highly sensitive detection of exocytotic dopamine release using a gold-nanoparticle-network microelectrode.

Here we report a new type of microelectrode sensor for single-cell exocytotic dopamine release. The new microsensor is built by forming a gold-nanoparticle (AuNP) network on a carbon fiber microelectrode. First a gold surface is obtained on a carbon fiber microdisk electrode by partially etching away the carbon followed by electrochemical deposition of gold into the pore. The gold surface is chemically functionalized with a sol-gel silicate network derived from (3-mercaptopropyl)trimethoxysilane (MPTS). A AuNP network is formed by immobilizing Au nanoparticles onto the thiol groups in the sol-gel silicate network. The AuNP-network microelectrode has been characterized by scanning electron microscopy (SEM) and steady-state voltammetry. The AuNP-network microelectrode has been used for amperometric detection of exocytotic dopamine secretion from individual pheochromocytoma (PC12) cells. The results show significant differences in the kinetic peak parameters including shorter rise time, decay time, and half-width as compared to a bare carbon fiber electrode equivalent. These results indicate AuNP-network microelectrodes possess an excellent sensing activity for single-cell exocytotic catecholamine release, specifically dopamine. Moreover, key advantageous properties inherent to bare carbon fiber microelectrodes (i.e., rigidity, flexibility, and small size) are maintained in addition to an observed prolonged shelf life stability and resistance to cellular debris fouling and dopamine polymerization.
