HYPHAEdelity: a quantitative image analysis tool for assessing peripheral whole colony filamentation.

The yeast Saccharomyces cerevisiae, also known as brewer's yeast, can undergo a reversible stress-responsive transition from individual ellipsoidal cells to chains of elongated cells in response to nitrogen- or carbon starvation. Whole colony morphology is frequently used to evaluate phenotypic switching response; however, quantifying two-dimensional top-down images requires each pixel to be characterized as belonging to the colony or background. While feasible for a small number of colonies, this labor-intensive assessment process is impracticable for larger datasets. The software tool HYPHAEdelity has been developed to semi-automate the assessment of two-dimensional whole colony images and quantify the magnitude of peripheral whole colony yeast filamentation using image analysis tools intrinsic to the OpenCV Python library. The software application functions by determining the total area of filamentous growth, referred to as the f-measure, by subtracting the area of the inner colony boundary from the outer-boundary area associated with hyphal projections. The HYPHAEdelity application was validated against automated and manually pixel-counted two-dimensional top-down images of S. cerevisiae colonies exhibiting varying degrees of filamentation. HYPHAEdelity's f-measure results were comparable to areas determined through a manual pixel enumeration method and found to be more accurate than other whole colony filamentation software solutions.

Evaluation of a competency based medical curriculum in a Sub-Saharan African medical school.

BACKGROUND: Medical schools in Sub-Saharan Africa have adopted competency based medical education (CBME) to improve the quality of graduates trained. In 2015, Makerere University College of Health Sciences (MaKCHS) implemented CBME for the Bachelor of Medicine and Bachelor of Surgery (MBChB) programme in order to produce doctors with the required attributes to address community health needs. However, no formal evaluation of the curriculum has been conducted to determine whether all established competencies are being assessed. OBJECTIVE: To evaluate whether assessment methods within the MBChB curriculum address the stated competencies. METHODS: The evaluation adopted a cross-sectional study design in which the MBChB curriculum was evaluated using an Essential Course Evidence Form (ECEF) that was developed to collect information about each assessment used for each course. Information was collected on: (1) Assessment title, (2) Description, (3) Competency domain (4) Sub-competency addressed, (5) Student instructions, and (6) Grading method/details. Data were entered into a structured Access data base. In addition, face-to-face interviews were conducted with faculty course coordinators. RESULTS: The MBChB curriculum consisted of 62 courses over 5 years, focusing on preclinical skills in years 1-2 and clinical skills in years 3-5. Fifty-nine competencies were identified and aggregated into 9 domains. Fifty-eight competencies were assessed at least one time in the curriculum. Faculty cited limited training in assessment as well as large student numbers as hindrances to designing robust assessments for the competencies. CONCLUSION: CBME was successfully implemented evidenced by all but one of the 59 competencies within the nine domains established being assessed within the MBChB curriculum at MaKCHS. Faculty interviewed were largely aware of it, however indicated the need for more training in competency-based assessment to improve the implementation of CBME.

"It Was Never Enough": The Meaning of Nurses' Experiences Caring for Patients during the COVID-19 Pandemic.

This study's aim was to understand nurses' caring experiences during the recent pandemic in the United States. Using an interpretive phenomenological approach, 15 participants provided the meaning of the care they provided. Five major themes were interpreted: If not us, then who?; Accepting uncertainty; It was never enough; Finding self and our voices in a new role; and Believing it was worth it. The study results have implications for psychiatric-mental health nurse clinicians as they identify and meet the needs of individuals of this vulnerable group. Research that uncovers the meaning of the caring experiences of front line nurses can illuminate the discipline's current understanding of this phenomena.

Stumbling toward Vulnerability: Recovery from Substance Use Disorders and Co-Occurring Mental Illness.

This study investigated the recovery process for individuals engaged in treatment for substance use disorders (SUDs) who had co-occurring anxiety and depression. The participants were eight individuals engaged in treatment. The results of a Grounded Theory design and methods revealed the core category and substantive theory, Stumbling toward Vulnerability. Four phases in which the participants progressed in a linear way emerged. The study results have implications for the role of the advance practice psychiatric-mental health nurse in the early assessment of mental illness for clients with SUDs by providing integrated treatment for these individuals, and focusing on health and wellness as a recovery outcome. Based on the findings, hypotheses for further research are recommended.

A Phenomenological Study of Nurse Managers' and Assistant Nurse Managers' Experiences during the COVID-19 Pandemic in the United States.

AIM: To understand the experiences of hospital nurse managers and assistant nurse managers during the COVID-19 pandemic in the United States. BACKGROUND: Little research has been published about the experiences of nurse managers during the COVID-19 pandemic. Experiences of front-line nurses have been well documented. This is the first phenomenological study to date in the United States on experiences of hospital nurse managers during the COVID-19 pandemic. DESIGN: Phenomenological qualitative approach. METHODS: Thirteen managers, seven nurse managers and six assistant nurse managers were interviewed about their experiences using audio-video teleconferencing and a semi-structured interview guide. Consolidated Criteria for Reporting Qualitative Research criteria for reporting qualitative research were used. RESULTS: The four major themes that emerged were as follows: being there for everyone; leadership challenges; struggles, support and coping; and strengthening my role. There were 11 subthemes. CONCLUSIONS: A major focus of nurse managers during the pandemic was psychosocial support of front-line nurses while at the same time experiencing stress and exhaustion themselves. IMPLICATIONS FOR NURSING MANAGEMENT: More attention on the psychosocial needs of nurse managers, interventions to allay their exhaustion and provisions for readily available support are warranted.

It's Not Just Physical: Exercise Physiologist-Led Exercise Program Promotes Functional and Psychosocial Health Outcomes in Aged Care.

Regular physical activity has multiple benefits for older adults, including improved physical, cognitive, and psychosocial health. This exploratory study investigated the benefits of a 12-week exercise program for older adults (n = 11 control and n = 13 intervention) living in a residential aged care facility in Perth, Western Australia. The program, prescribed and delivered by an accredited exercise physiologist, aimed to maintain or improve participants' physical capacity. It comprised one-on-one exercise sessions (1 hr × 2 days/week × 12 weeks), involving a components-approach intervention. Physical performance measures (balance, strength, flexibility, and mobility) were assessed preintervention and postintervention. Qualitative interviews postintervention with residents participating in the exercise intervention, and with family members, staff, and research team members, explored barriers and enablers to participation and perceived psychosocial outcomes. Findings indicate the program provided physical benefits and enhanced social engagement for participants, illustrating the value of providing exercise physiology services in the aged care sector.

Nurses' Perceptions of Their Practice Following a Redesign Initiative.

A significant number of quantitative studies have associated a positive or healthy work environment with job satisfaction. Nurses, patients, and organizational characteristics have been studied as contributing factors. Other studies have focused on structural or physical environmental factors such as noise, space, or lighting as influencing to satisfaction. Little research has focused on how a changed work environment initiated by an organization for improved patient care affected the nurses' perceptions of how their practice had changed. The purpose of this qualitative study was to determine nurses' perceptions of a changed work environment on their practice, specifically patient care. Twelve nurses participated in the semistructured interviews. Interviews were transcribed verbatim and content analysis was used to identify categories of phrases and the resulting major themes. Most importantly, and the significant overall theme of patient- and family-centered improved care described their perceptions of this change. Other themes included camaraderie, nurse-patient relationships, being valued by the organization, and efficiency for decreasing stress. The results illuminate and extend some of the findings from prior quantitative studies on professional practice environments. A major contribution of this research is the perception of the nurses, often overlooked in quantitative studies. Significant was the nurses' view that the changed environment improved patient- and family-centered care although, as in other study findings, there was a view that peer camaraderie decreased.

Inotuzumab ozogamicin versus standard of care in relapsed or refractory acute lymphoblastic leukemia: Final report and long-term survival follow-up from the randomized, phase 3 INO-VATE study.

BACKGROUND: Inotuzumab ozogamicin (InO) is an antibody-drug conjugate used for adults with relapsed/refractory B-cell precursor (BCP) acute lymphoblastic leukemia (ALL). The INotuzumab Ozogamicin trial to inVestigAte Tolerability and Efficacy (INO-VATE) previously reported improved outcomes with InO versus standard-of-care (SoC) chemotherapy. This article reports the final INO-VATE results (≥2 years of follow-up) and additional analyses of patient characteristics associated with improved outcomes. METHODS: Between August 27, 2012, and January 4, 2015, this multicenter, parallel, open-label, phase 3 trial randomized 326 adults with relapsed/refractory ALL to InO (n = 164) or SoC (n = 162); 307 received 1 or more doses of the study drug (164 in the InO arm and 143 in the SoC arm). RESULTS: The complete remission (CR)/complete remission with incomplete hematologic recovery (CRi) rate was higher with InO versus SoC (73.8% vs 30.9%; 1-sided P < .0001), with consistent CR/CRi rates across patient subgroups. The median overall survival (OS) was 7.7 months with InO and 6.2 months with SoC, with 2-year OS rates of 22.8% and 10.0%, respectively (overall hazard ratio, 0.75; 97.5% confidence interval [CI], 0.57-0.99; 1-sided P = .0105). The predictors of OS with InO were the best minimal residual disease status, baseline platelet count, duration of first remission, achievement of CR/CRi, and follow-up hematopoietic stem cell transplantation (HSCT; all 2-sided P values < .05). More InO arm patients proceeded directly to HSCT after achieving CR/CRi before any follow-up induction therapy (39.6% [95% CI, 32.1%-47.6%] vs 10.5% [6.2%-16.3%]; 1-sided P < .0001). The most frequent all-grade and grade 3 or higher adverse events in both arms were hematologic. Veno-occlusive disease (VOD)/sinusoidal obstruction syndrome (SOS) was more frequent with InO (23 of 164 [14.0%] vs 3 of 143 [2.1%]). CONCLUSIONS: In patients with relapsed/refractory BCP ALL in INO-VATE, InO was associated with a greater likelihood of CR/CRi across key patient subgroups, and it served as a bridge to HSCT. Potential VOD/SOS risk factors must be considered when InO treatment decisions are being made.

Prognostic implications of cytogenetics in adults with acute lymphoblastic leukemia treated with inotuzumab ozogamicin.

Karyotype is frequently used to predict response and outcome in leukemia. This post hoc exploratory analysis evaluated the relationship between baseline cytogenetics and outcome in patients with relapsed/refractory acute lymphoblastic leukemia (R/R ALL) treated with inotuzumab ozogamicin (InO), a humanized CD22 antibody conjugated to calicheamicin, in the phase 3, open-label, randomized INO-VATE trial. Data as of March 8, 2016, are presented in this analysis. Of the 326 patients randomized, 284 had screening karyotyping data (144 in the InO arm and 140 in the standard care [SC] arm). With InO, complete remission or complete remission with incomplete hematologic recovery (CR/CRi), minimal residual disease negativity rates, and overall survival (OS) were not significantly different between cytogenetic subgroups. CR/CRi rates favored InO over SC in the diploid with ≥20 metaphases, complex, and "other" cytogenetic subgroups. The OS hazard ratio favored InO over SC in the diploid with ≥20 metaphases, complex, and other cytogenetic subgroups. Generally, InO is effective and provides substantial clinical benefit in patients with R/R ALL who have specific baseline karyotypes.

The relationship amongst ethical position, religiosity and self-identified culture in student nurses.

BACKGROUND/PURPOSE: Research from other disciplines demonstrates that ethical position, idealism, or relativism predicts ethical decision-making. Individuals from diverse cultures ascribe to various religious beliefs and studies have found that religiosity and culture affect ethical decision-making. Moreover, little literature exists regarding undergraduate nursing students' ethical position; no studies have been conducted in the United States on students' ethical position, their self-identified culture, and intrinsic religiosity despite an increase in the diversity of nursing students across the United States. PARTICIPANTS AND RESEARCH CONTEXT OBJECTIVES: The study's two aims were to determine the relationship of self-identified culture, religiosity, and ethics position of undergraduate nursing student and whether students' level of education and past ethics courses taken related to idealism. Two hundred and twelve volunteer undergraduate students participated. RESEARCH DESIGN: A descriptive cross-sectional study was designed for participants who completed the Ethical Position Questionnaire, The intrinsic subscale of the Religious Orientation Scale, and a Demographic, Cultural, Ethnicity Form. To test the five hypotheses, analyses included t-tests, correlations, and ANOVA. ETHICAL CONSIDERATIONS: The study was approved by the Institutional Review Board at Adelphi University. RESULTS: Idealism and intrinsic religiosity were significantly related. Differences were observed for intrinsic religiosity and idealism for cultural identity and cultural dimensions such as parents' place of birth, and if participants were US born. Students' level of education or participation in past courses on ethics did not influence idealism. CONCLUSIONS: The study's findings were similar to most of the research from other disciplines on culture, ethics position, and religiosity. Generic courses on ethics taken prior to clinical work may not assist nursing students in integrating principles into complex ethical dilemmas. Self-identified culture, religion, and intrinsic religiosity related to ethics position; completing ethics courses and level of education, juniors compared with seniors, did not influence idealism. Faculty should consider integrating students' culture, religious orientation, and ethics position into teaching ethics for all levels of nursing education.

Dacomitinib versus gefitinib as first-line treatment for patients with EGFR-mutation-positive non-small-cell lung cancer (ARCHER 1050): a randomised, open-label, phase 3 trial.

BACKGROUND: Dacomitinib is a second-generation, irreversible EGFR tyrosine kinase inhibitor. We compared its efficacy and safety with that of the reversible EGFR tyrosine kinase inhibitor gefitinib in the first-line treatment of patients with advanced EGFR-mutation-positive non-small-cell lung cancer (NSCLC). METHODS: In this international, multicentre, randomised, open-label, phase 3 study (ARCHER 1050), we enrolled adults (aged ≥18 years or ≥20 years in Japan and South Korea) with newly diagnosed advanced NSCLC and one EGFR mutation (exon 19 deletion or Leu858Arg) at 71 academic medical centres and university hospitals in seven countries or special administrative regions. We randomly assigned participants (1:1) to receive oral dacomitinib 45 mg/day (in 28-day cycles) or oral gefitinib 250 mg/day (in 28-day cycles) until disease progression or another discontinuation criterion was met. Randomisation, stratified by race and EGFR mutation type, was done with a computer-generated random code assigned by a central interactive web response system. The primary endpoint was progression-free survival assessed by masked independent review in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, number NCT01774721, and is ongoing but no longer recruiting patients. FINDINGS: Between May 9, 2013, and March 20, 2015, 452 eligible patients were randomly assigned to receive dacomitinib (n=227) or gefitinib (n=225). Median duration of follow-up for progression-free survival was 22·1 months (95% CI 20·3-23·9). Median progression-free survival according to masked independent review was 14·7 months (95% CI 11·1-16·6) in the dacomitinib group and 9·2 months (9·1-11·0) in the gefitinib group (hazard ratio 0·59, 95% CI 0·47-0·74; p<0·0001). The most common grade 3-4 adverse events were dermatitis acneiform (31 [14%] of 227 patients given dacomitinib vs none of 224 patients given gefitinib), diarrhoea (19 [8%] vs two [1%]), and raised alanine aminotransferase levels (two [1%] vs 19 [8%]). Treatment-related serious adverse events were reported in 21 (9%) patients given dacomitinib and in ten (4%) patients given gefitinib. Two treatment-related deaths occurred in the dacomitinib group (one related to untreated diarrhoea and one to untreated cholelithases/liver disease) and one in the gefitinib group (related to sigmoid colon diverticulitis/rupture complicated by pneumonia). INTERPRETATION: Dacomitinib significantly improved progression-free survival over gefitinib in first-line treatment of patients with EGFR-mutation-positive NSCLC and should be considered as a new treatment option for this population.

White Paper AGA: An Episode-of-Care Framework for the Management of Obesity-Moving Toward High Value, High Quality Care: A Report From the American Gastroenterological Association Institute Obesity Episode of Care and Bundle Initiative Work Group.

The American Gastroenterological Association acknowledges the need for gastroenterologists to participate in and provide value-based care for both cognitive and procedural conditions. Episodes of care are designed to engage specialists in the movement toward fee for value, while facilitating improved outcomes and patient experience and a reduction in unnecessary services and overall costs. The episode of care model puts the patient at the center of all activity related to their particular diagnosis, procedure, or health care event, rather than on a physician's specific services. It encourages and incents communication, collaboration, and coordination across the full continuum of care and creates accountability for the patient's entire experience and outcome. This paper outlines a collaborative approach involving multiple stakeholders for gastrointestinal practices to assess their ability to participate in and implement an episode of care for obesity and understand the essentials of coding and billing for these services.

Exploring the factors that influence the decision to adopt and engage with an integrated assistive telehealth and telecare service in Cambridgeshire, UK: a nested qualitative study of patient 'users' and 'non-users'.

BACKGROUND: There is a political drive in the UK to use assistive technologies such as telehealth and telecare as an innovative and efficient approach to healthcare delivery. However, the success of implementation of such services remains dependent on the ability to engage the wider population to adopt these services. It has been widely acknowledged that low acceptance of technology, forms a key barrier to adoption although findings been mixed. Further, it remains unclear what, if any barriers exist between patients and how these compare to those who have declined or withdrawn from using these technologies. This research aims to address this gap focusing on the UK based Cambridgeshire Community Services Assistive Telehealth and Telecare service, an integrated model of telehealth and telecare. METHODS: Qualitative semi-structured interviews were conducted between 1st February 2014 and 1st December 2014, to explore the views and experiences of 'users' and 'non-users' using this service. 'Users' were defined as patients who used the service (N = 28) with 'non-users' defined as either referred patients who had declined the service before allocation (N = 3) or had withdrawn after using the ATT service (N = 9). Data were analysed using the Framework Method. RESULTS: This study revealed that there are a range of barriers and facilitators that impact on the decision to adopt and continue to engage with this type of service. Having a positive attitude and a perceived need that could be met by the ATT equipment were influential factors in the decision to adopt and engage in using the service. Engagement of the service centred on 'usability', 'usefulness of equipment', and 'threat to identity and independence'. CONCLUSIONS: The paper described the influential role of referrers in decision-making and the need to engage with such agencies on a strategic level. The findings also revealed that reassurance from the onset was paramount to continued engagement, particularly in older patients who appeared to have more negative feelings towards technology. In addition, there is a clear need for continued product development and innovation to not only increase usability and functionality of equipment but also to motivate other sections of the population who could benefit from such services. Uncovering these factors has important policy implications in how services can improve access and patient support through the application of assistive technology which could in turn reduce unnecessary cost and burden on overstretched health services.

Emergency room psychiatric services: a qualitative study of nurses' experiences.

Emergency nurses working in general emergency divisions (EDs) are primarily trained to assess and treat acute physical problems. However, ED nurses often care for psychiatric patients and the perceptions of nurses in EDs regarding their experiences with psychiatric patients have not been well-studied. Using focus groups, the purpose of this study was to explore and describe ED nurses' experiences, and feelings caring for patients with mental illness. Krueger and Casey's qualitative analysis for focus groups was utilized to code and categorize phrases and identify themes from transcribed interviews. Four themes emerged; powerlessness best captured the overarching and substantive experience of the participants. Based on the findings, implications for emergency room care of psychiatric patients are described.

How Can Framed Mammography Screening Messages Be Optimally Persuasive for Foreign-Born Chinese American Women?

BACKGROUND: Foreign-born Chinese American women (FBCAW) have the lowest mammography rates compared with other racial groups despite the overwhelming evidence of the benefits of screening. Message framing based on the prospect theory has shown significant but inconsistent effects on mammogram screening among ethnic minority groups. OBJECTIVE: Using data from a randomized controlled trial, this secondary analysis aims to identify factors that interact with message framing to improve mammography screening in FBCAW. METHODS: In the parent study, participants were randomized to receive either a gain- or loss-framed brochure that encouraged mammography screening. Data were collected at baseline and 2 months using validated questionnaires. For this secondary analysis, ordinal logistic regression was performed to identify moderation effects using both per-protocol and intention-to-treat principles. RESULTS: Participants predominantly had low income, a low level of English proficiency, and no insurance. Lack of access to mammography services, knowledge of making a mammogram appointment, knowledge of insurance coverage for breast cancer treatment, education levels, and mammogram history were significant moderators of the framing effects. Overall, the moderation effects were larger when using per-protocol analysis. Some moderation results under intention-to-treat analysis were different from those using per-protocol analysis. CONCLUSIONS: The persuasive effects of the loss- or gain-framed messages depend on the characteristics of FBCAW. Future studies can identify algorithms to select tailored messages that match individual FBCAW's characteristics to optimize the effects of framed messages. IMPLICATIONS FOR PRACTICE: Findings of this study can guide healthcare providers, especially nurses, to choose different wording when communicating with their clients.

Disparity in pseudohyphal morphogenic switching response to the quorum sensing molecule 2-phenylethanol in commercial brewing strains of Saccharomyces cerevisiae.

Saccharomyces cerevisiae can undergo filamentous growth in response to specific environmental stressors, particularly nitrogen-limitation, whereby cells undergo pseudohyphal differentiation, a process where cells transition from a singular ellipsoidal appearance to multicellular filamentous chains from the incomplete scission of the mother-daughter cells. Previously, it was demonstrated that filamentous growth in S. cerevisiae is co-regulated by multiple signaling networks, including the glucose-sensing RAS/cAMP-PKA and SNF pathways, the nutrient-sensing TOR pathway, the filamentous growth MAPK pathway, and the Rim101 pathway, and can be induced by quorum-sensing aromatic alcohols, such as 2-phenylethanol. However, the prevalent research on the yeast-pseudohyphal transition and its induction by aromatic alcohols in S. cerevisiae has been primarily limited to the strain Σ1278b. Due to the prospective influence of quorum sensing on commercial fermentation, the native variation of yeast-to-filamentous phenotypic transition and its induction by 2-phenylethanol in commercial brewing strains was investigated. Image analysis software was exploited to enumerate the magnitude of whole colony filamentation in 16 commercial strains cultured on nitrogen-limiting SLAD medium; some supplemented with exogenous 2-phenylethanol. The results demonstrate that phenotypic switching is a generalized, highly varied response occurring only in select brewing strains. Nevertheless, strains exhibiting switching behavior altered their filamentation response to exogenous concentrations of 2-phenylethanol.

Communication services for First Nations peoples after stroke and traumatic brain injury: Alignment of Sustainable Development Goals 3, 16 and 17.

PURPOSE: Colonisation and continuing discrimination have significantly and negatively impacted the physical, social and emotional wellbeing of First Nations peoples globally. In Australia, Aboriginal cultures thrive despite ongoing barriers to health care. This paper describes challenges and new initiatives for Australian Aboriginal people with acquired communication disability after brain injury and their alignment with the global aims forming the Sustainable Development Goals. RESULT: Research undertaken by an Aboriginal and non-Aboriginal multidisciplinary team over a decade in Western Australia identified and responded to mismatches between community needs and services. Initiatives described include the Missing Voices, Healing Right Way, Brain Injury Yarning Circles and Wangi/Yarning Together projects. Recommendations implemented related to (a) greater incorporation of Aboriginal cultural protocols and values within services, (b) more culturally secure assessment and treatment tools, (c) support after hospital discharge, (d) Aboriginal health worker involvement in support. Implementation includes cultural training of hospital staff, trialling new assessment and treatment methods, and establishing community-based Aboriginal Brain Injury Coordinator positions and relevant peer support groups. CONCLUSION: Culturally secure brain injury rehabilitation in Australia is in its infancy. Our initiatives challenge assumptions about worldviews and established Western biomedical models of healthcare through incorporating Indigenous methodologies and leadership, and community-driven service delivery. This commentary paper focuses on Sustainable Development Goals 3, 16 and 17.

Seeing Voices: A Dynamic, Interprofessional Approach to Teaching Performing Arts and Speech-Language Pathology Students About Vocal Anatomy and Physiology.

OBJECTIVES: Seeing Voices was an interprofessional, technology-enabled, large-scale, teaching and learning event developed to address the need to improve voice students' knowledge of laryngeal anatomy and physiology toward understanding and maintaining vocal health. Seeing Voices trialed a novel interprofessional educational approach, collected both quantitative and qualitative data about student experiences of laryngostroboscopic examination, and built a databank of laryngeal recordings for future student learning. METHODS: Seeing Voices involved two 3-hour seminars in a large, university lecture space, run by an interprofessional team (speech-language pathologists, vocal coach, Ear Nose and Throat consultant) with quality equipment projecting laryngeal images to large screens with expert commentary in real time. Participants were 18 students who volunteered for laryngeal examination (9 per seminar) and student attendees (n = 175) from performing arts courses (classical singing, contemporary, jazz, musical theater, acting) and a speech-language pathology course. A quantitative evaluation of knowledge gained was undertaken using a Qualtrics survey. Results from pre (n = 175; performing arts = 120; speech-language pathology (SLP) = 55) and postevent (n = 99; performing arts = 56; SLP = 43) questionnaires were received from the students who attended. Interviews were collected from 15 of the 18 student volunteers about their experiences of nasendoscopic evaluation and data were analyzed using qualitative description and qualitative content analysis. RESULTS: Quantitative results demonstrated a strong trend toward increased knowledge following attendance at the event across year cohorts for both student groups. Qualitative interviews highlighted the value in seeing multiple examples of normal laryngeal functioning across different vocal techniques in real time. For those undertaking nasendoscopic examination, simultaneously seeing and feeling laryngeal maneuvers used in training appeared to promote understanding of their own vocal mechanism and the purpose of different vocal techniques. CONCLUSIONS: Seeing Voices offers a novel way to improve interprofessional collaboration, and engagement with, and understanding of, laryngeal anatomy and vocal health by students in performing arts and speech-language pathology courses.

Leveraging mHealth and Patient Supporters for African Americans' and Latinxs' Engagement in HIV Care (LEAN): Protocol for a Randomized, Controlled, Effectiveness-Implementation Trial.

BACKGROUND: Despite substantial investments in ending the HIV epidemic, disparities in HIV care persist, and there is an urgent need to evaluate novel and scalable approaches to improving HIV care engagement and viral suppression in real-world settings. OBJECTIVE: This paper aims to describe a study protocol for a pragmatic type II hybrid effectiveness-implementation randomized controlled trial comparing existing standard of care clinic HIV linkage, adherence, and retention (LAR) protocols to a mobile health (mHealth)-enhanced linkage, adherence, and retention (mLAR) intervention. METHODS: The study will enroll 450 participants from clinics in Baltimore City. Eligibility criteria include being ≥18 years of age, having a new HIV diagnosis or being HIV-positive and out of care, or being HIV-positive and deemed by clinic staff as someone who could benefit from linkage and retention services. Participants randomized to the intervention receive mHealth-supported patient navigation for 12 months. Participants in the control group receive the referring clinic's standard of care patient support. The primary outcome is HIV virologic suppression at 12 months. A subset of participants will be interviewed at 12 months to learn about their HIV care experiences and, for those in the intervention arm, their experiences with the mLAR intervention. This protocol was developed in collaboration with the Baltimore City Health Department (BCHD) and the Maryland Department of Health (MDH) and with input from a community advisory board. RESULTS: Enrollment began on February 25, 2020. As of August 11, 2022, 411 of the 450 target participants had been enrolled. CONCLUSIONS: Pragmatic implementation science trials designed with input from key stakeholders, including health departments and community members, can help evaluate the evidence for mHealth interventions to reduce HIV health disparities. TRIAL REGISTRATION: ClinicalTrials.gov NCT03934437; https://clinicaltrials.gov/ct2/show/NCT03934437. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/42691.

Impact of latently infected cells on strain archiving within HIV hosts.

Latently infected cells are a barrier to HIV eradication on therapy due to long half-lives of between 6 and 44 months. The mechanism behind this long term maintenance is unclear although bystander proliferation and asymmetric division have both been put forward for consideration in mathematical models. The latently infected cell reservoir seems to act as an archive for strains of HIV no longer dominant in the blood, such as wild-type virus when the individual is on therapy. This is particularly significant when patients wish to come off medication and wild-type virus re-emerges. We use a two target cell model capable of producing low-level viral load on therapy and include latent cells and two strains of virus, wild-type and drug resistant, to investigate the impact of two possible mechanisms of latent cell reservoir maintenance on strain archiving. We find that although short term (less than a year) archiving of viral strains is possible in a model with no mechanism for reservoir maintenance, both bystander proliferation and asymmetric division of latent cells allow archiving to occur over much longer timescales (2 or more years). We suggest that regardless of the mechanism involved, latent cell reservoir maintenance allows strain archiving to occur. We interpret our results for clinical consideration.
