ABSTRACT
Background: Cardiac rehabilitation is a beneficial multidisciplinary treatment of exercise promotion, patient education, risk factor management, and psychosocial counseling for people with coronary heart disease (CHD) that is underutilized due to substantial disparities in access, referral, and participation. Empirical studies suggest that cardiac telerehabilitation (CTR) have safety and efficacy comparable to traditional in-person cardiac rehabilitation, however, older adults are under-reported with effectiveness, feasibility, and usability remains unclear. Methods: The study randomized 43 older adults (84 % males) to the 12-week CTR intervention or standard of care. Guided by Social Cognitive Theory, participants received individualized in-person assessment and e-coaching sessions, followed by CTR usage at home. Data were collected at baseline (T0), six-week (T1), and 12-week (T2). Results: Participants in the CTR intervention group showed significant improvement in daily steps (T1: ß = 4126.58, p = 0.001; T2: ß = 5285, p = 0.01) and health-promoting lifestyle profile (T1: ß = 23.26, p < 0.001; T2: ß = 12.18, p = 0.008) across study endpoints. Twenty participants completed the intervention, with 40 % used the website for data-uploading or experiential learning, 90 % used the pedometer for tele-monitoring. Improving awareness of rehabilitation and an action focus were considered key facilitators while physical discomforts and difficulties in using the technology were described as the main barriers. Conclusions: The CTR is feasible, safe and effective in improving physical activity and healthy behaviors in older adults with CHD. Considering the variation in individual cardiovascular risk factors, full-scale RCT with a larger sample is needed to determine the effect of CTR on psychological symptoms, body weight and blood pressure, and quality of life.
ABSTRACT
A study was conducted to investigate the chemical composition and feeding value of rapeseed meal (RSM) batches produced at the same plant when fed to turkey poults. In total, seven RSM samples were obtained from a single manufacturer within a period of 90 days. Although the manufacturer followed the same procedures during oil extraction and RSM production, different batches of rapeseed were used. A balancer feed (BF) was formulated to contain 11.85 MJ/kg ME and 265 g/kg crude protein. Seven nutritionally complete test mash diets were prepared by mixing 200 g/kg of each RSM batch sample with 800 g/kg of the BF, totalling 8 diets. Diets were fed to female B.U.T. Premium turkeys from 12 to 21 d of age. Each diet was fed to six raised floor pens, housing two birds, following randomisation. During the experiment, a nitrogen corrected apparent metabolisable energy (AMEn) assay was performed using a total collection technique. The AMEn in RSM samples was calculated based on the differences between the AMEn values of basal and test diets. Associations were examined between AMEn and the chemical composition of the RSM samples. The overall determined AMEn value of the RSM ranged from 5.50 MJ/kg DM to 8.53 MJ/kg DM, giving an average AMEn of 7.29 MJ/kg DM. There was no difference (p > 0.05) in AMEn content between batches. There was a negative correlation (r = - 0.864; p < 0.05) between AMEn values and the neutral detergent fibre (NDF) content of the RSM samples. The results suggest that the NDF could be a good predictor of the AMEn of industry produced RSM. It may be inferred that processing rather than cultivar could be the main factor determining the feeding value of RSM for turkeys.
ABSTRACT
PURPOSE: Less than 50% of people with HIV (PWH) in the United States are retained in care, a key step along the HIV care continuum. We examined the impact of geographic access to care on retention in care for urban and rural PWH. METHODS: We used Medicaid claims and clinician data (Medicaid Analytic eXtract and MAX Provider Characteristics, 2009-2012) for 13 Southern states plus the District of Columbia. We calculated drive time from the enrollees' ZIP Code Tabulation Area to their usual source of care. We used generalized estimating equations to examine the association between drive time to care >30 min (versus ≤30 min) and retention in care, overall and stratified by rurality. In sensitivity analysis, we examined the definition of retention in care, states included in the analysis, and enrollee- and care-related characteristics. FINDINGS: The sample included 49,596 PWH. Overall, the association between drive time >30 min and retention was significant, but small (adjusted odds ratio [aOR] 1.01, 95% confidence interval [CI] 1.00, 1.01) and was not significant in urban areas; however, the significance and direction of the association differed in sensitivity analysis. In rural areas, driving >30 min to care was associated with 7% higher odds of retention in care (aOR 1.07, 95% CI 1.05, 1.08) and this association remained significant and positive in nearly all sensitivity analyses. CONCLUSIONS: For PWH in rural areas, greater drive time is consistently associated with greater retention in care. Disentangling the mechanisms of this relationship is a future research priority.
ABSTRACT
OBJECTIVES: The aim of this study was to investigate GPT-3.5 in generating and coding medical documents with International Classification of Diseases (ICD)-10 codes for data augmentation on low-resource labels. MATERIALS AND METHODS: Employing GPT-3.5 we generated and coded 9606 discharge summaries based on lists of ICD-10 code descriptions of patients with infrequent (or generation) codes within the MIMIC-IV dataset. Combined with the baseline training set, this formed an augmented training set. Neural coding models were trained on baseline and augmented data and evaluated on an MIMIC-IV test set. We report micro- and macro-F1 scores on the full codeset, generation codes, and their families. Weak Hierarchical Confusion Matrices determined within-family and outside-of-family coding errors in the latter codesets. The coding performance of GPT-3.5 was evaluated on prompt-guided self-generated data and real MIMIC-IV data. Clinicians evaluated the clinical acceptability of the generated documents. RESULTS: Data augmentation results in slightly lower overall model performance but improves performance for the generation candidate codes and their families, including 1 absent from the baseline training data. Augmented models display lower out-of-family error rates. GPT-3.5 identifies ICD-10 codes by their prompted descriptions but underperforms on real data. Evaluators highlight the correctness of generated concepts while suffering in variety, supporting information, and narrative. DISCUSSION AND CONCLUSION: While GPT-3.5 alone given our prompt setting is unsuitable for ICD-10 coding, it supports data augmentation for training neural models. Augmentation positively affects generation code families but mainly benefits codes with existing examples. Augmentation reduces out-of-family errors. Documents generated by GPT-3.5 state prompted concepts correctly but lack variety, and authenticity in narratives.

Purpose: Given rising demand for gender affirmation surgery (GAS), lesbian, gay, bisexual, transgender, queer, and others' (LGBTQ+) patient care, and sexual and gender minority (SGM) representation in plastic surgery, we sought to analyze integrated residency programs' posts for LGBTQ+ content. Methods: Programs were identified from the American Council of Academic Plastic Surgeons website. Accounts were searched for on Instagram, Facebook, and Twitter. Posts uploaded through June 24, 2021 were analyzed. Mann-Whitney U- and Kruskal-Wallis tests were used to compare content between programs. Results: Of 82 programs, 76 (92.7%), 31 (37.8%), and 30 (36.6%) have Instagram, Facebook, and Twitter accounts, respectively. Two hundred eighty-one (1.3%) posts displayed LGBTQ+ content, including educational (29.9%), research (17.4%), news (11.0%), resident interests (10.7%), pride/diversity (9.6%), posts to attract applicants/patients (7.5%), operative/clinic cases (6.8%), faculty spotlights (6.4%), and patient testimonials (1.1%). One hundred eighty-one (64.4%) posts described GAS overall, 42 (23.2%) described top, 32 (17.7%) described genital, and 32 (17.7%) described facial surgery. Instagram and Facebook have more LGBTQ+ content than Twitter (p≤0.037). Newly accredited programs have significantly more LGBTQ+ content on Facebook (p=0.036). Programs in the West, having more perceived prestige, or GAS fellowships tended to have more LGBTQ+ content. Conclusion: Despite growing demand for GAS and thus training, 1% of content on plastic surgery residency social media accounts is LGBTQ+ related. Reasons for lack of representation require further investigation but may include (1) limited GAS and LGBTQ+ patient exposure during training or (2) lack of SGM inclusivity for residents, faculty, and patients.
ABSTRACT
Liquid-liquid phase separation is reported to enhance the catalytic reaction rates severalfold. Herein, we explored the interactions between a catalyst and a range of substrate concentrations to understand the impact on the droplet phase and catalytic reaction kinetics. We observed that the substrate above a critical concentration induces phase transitions within liquid condensates and restricts the free movement of both the substrate and products, resulting in an overall reduction of the reaction rate, an observation not reported earlier.
ABSTRACT
Despite the popularity of electronic cigarettes (ECIGs), limited research has examined the role of sweeteners, independent of other flavors, in shaping ECIG human abuse potential (HAP). This study examined the effects of sucralose and nicotine in unflavored ECIG liquid solutions to provide a basic understanding of the effects of sweeteners on ECIG HAP compared to combustible cigarettes. Individuals who smoked cigarettes daily (N = 14) completed five within-subject, Latin-square ordered study sessions that differed by product used: (a) own-brand combustible cigarettes (OB), (b) 0 mg/mL nicotine, unsweetened liquid, (c) 0 mg/mL nicotine, sucralose-sweetened liquid, (d) 15 mg/mL nicotine, unsweetened liquid, and (e) 15 mg/mL nicotine, sucralose-sweetened liquid. Participants completed subjective questionnaires and behavioral tasks following a 10-puff directed use bout during which puff topography was measured, and blood was sampled for later measurement of plasma nicotine concentration. On average, the OB condition had a greater increase in plasma nicotine concentration and produced more pronounced subjective effects compared to the ECIG conditions. The 15 mg/mL nicotine ECIGs delivered significantly more nicotine and produced greater drug effects and reductions in tobacco abstinence symptoms than the 0 mg/mL nicotine ECIGs. Sucralose-containing solutions increased ECIG product appeal, puff duration, and puff volume during the 10-puff directed bout. Findings revealed greater HAP for OB cigarettes relative to all ECIGs tested and suggest that adding sucralose and nicotine elevates ECIG HAP via different mechanisms; sucralose appears to influence HAP through product appeal, while nicotine influences HAP through drug effects and tobacco/nicotine abstinence symptom suppression.

We report on experiments where solid-density Mg plasmas are created by heating with the focused output of the Linac Coherent Light Source x-ray free-electron laser. We study the K-shell emission from the helium- and lithium-like ions using Bragg crystal spectroscopy. Observation of the dielectronic satellites in lithium-like ions confirms that the M-shell electrons appear bound for these high charge states. An analysis of the intensity of these satellites indicates that when modeled with an atomic-kinetics code, the ionization potential depression model employed needs to produce depressions for these ions which lie between those predicted by the well known Stewart-Pyatt and Ecker-Kroll models. These results are largely consistent with recent density functional theory calculations.
ABSTRACT
Sequencing human viruses in wastewater is challenging due to their low abundance compared to the total microbial background. This study compared the impact of four virus concentration/extraction methods (Innovaprep, Nanotrap, Promega, and Solids extraction) on probe-capture enrichment for human viruses followed by sequencing. Different concentration/extraction methods yielded distinct virus profiles. Innovaprep ultrafiltration (following solids removal) had the highest sequencing sensitivity and richness, resulting in the successful assembly of several near-complete human virus genomes. However, it was less sensitive in detecting SARS-CoV-2 by digital polymerase chain reaction (dPCR) compared to Promega and Nanotrap. Across all preparation methods, astroviruses and polyomaviruses were the most highly abundant human viruses, and SARS-CoV-2 was rare. These findings suggest that sequencing success can be increased using methods that reduce nontarget nucleic acids in the extract, though the absolute concentration of total extracted nucleic acid, as indicated by Qubit, and targeted viruses, as indicated by dPCR, may not be directly related to targeted sequencing performance. Further, using broadly targeted sequencing panels may capture viral diversity but risks losing signals for specific low-abundance viruses. Overall, this study highlights the importance of aligning wet lab and bioinformatic methods with specific goals when employing probe-capture enrichment for human virus sequencing from wastewater.

Until recently, wastewater-based monitoring for pathogens of public health concern primarily used PCR-based quantification methods and targeted sequencing for specific pathogens (e.g., SARS-CoV-2). In the past three years, researchers have expanded sequencing to monitor a broad range of pathogens, applying probe capture enrichment to wastewater. The goals of those studies included (1) monitoring and expanding fundamental knowledge of disease dynamics for known pathogens and (2) evaluating the potential for early detection of emerging diseases resulting from zoonotic spillover or novel viral variants. Several studies using off-the-shelf probe panels designed for clinical and environmental surveillance reported that enrichment increased virus relative abundance but did not recover complete genomes for most nonenteric viruses. Based on our experience and recent results reported by others using these panels for wastewater, clinical, and synthetic samples, we discuss challenges and technical factors that affect the rates of false positive and false negative results. We identify trade-offs and opportunities throughout the workflow, including in wastewater sample processing, probe panel design, and bioinformatic analysis. We suggest tailored methods of virus concentration and background removal, carefully designed probe panels, and multithresholded bioinformatics analysis.

INTRODUCTION: Research is key to academic advancement in plastic surgery. However, access to publication opportunities may be inequitable as seen in other fields. We compared authorship trends of plastic surgery manuscripts that underwent single-blinded review (SBR) versus double-blinded review (DBR) to identify potential disparities in publication opportunities. METHODS: Publications from two plastic surgery journals using SBR and two using DBR from September 2019 to September 2021 were evaluated. Name and institution of the article's first and senior author and journal's editor-in-chief (EIC) were recorded. Chi-squared and Fisher's exact analyses were used to compare author characteristics between SBR and DBR articles. RESULTS: Of 2500 manuscripts, 65.7% underwent SBR and 34.3% underwent DBR. SBR articles had higher percentages of women as first authors (31.9% versus 24.3%, P < 0.001) but lower percentages of first (50.7% versus 71.2%, P < 0.001) and senior (49.6% versus 70.3%, P < 0.001) authors from international institutions. First (26.0% versus 12.9%, P < 0.001) and senior (27.9% versus 18.0%, P = 0.007) authors of SBR articles tended to have more plastic surgery National Institutes of Health funding. Journals using SBR tended to have higher rates of authorship by EICs or authors sharing institutions with the EIC (P ≤ 0.005). CONCLUSIONS: While associated with greater female first authorship suggesting potential efforts toward gender equity in academia, SBR of plastic surgery articles tends to favor authors from institutions with higher National Institutes of Health funding and disadvantage authors from international or lower-resourced programs. Careful consideration of current peer-review proceedings may make publication opportunities more equitable.

BACKGROUND: There was a substantial documented call for healthcare professionals to provide compassionate care during the COVID-19 pandemic and significant criticism voiced when it was lacking. This study aimed to explore perspectives on compassionate care among healthcare professionals providing care during the COVID-19 pandemic. The study focuses on healthcare professionals who participated in a wide range of COVID-19 measures, including testing, quarantine, diagnosis, and care provision (patients with COVID-19 or patients with other illnesses and comorbid with COVID-19). METHODS: A qualitative design with an interpretative phenomenological analysis approach was used. Twenty frontline healthcare professionals (15 nurses and five physicians) who had worked in COVID-19 facilities in China were interviewed individually. RESULTS: Participants stated that a commitment to 'offering oneself' and 'balancing the advantages/disadvantages' in providing care during the pandemic were key to alleviate population-level suffering. On a personal level, they described a desire for obtaining 'mutual support' and improving 'professional competencies' to safeguard their physical and mental well-being. Two professional competencies were notable: coping with grief and implementing infection control across the organization. Additionally, they emphasized the importance of receiving support from the health care organization, the public, and leaders in creating an 'environment conducive to fostering compassionate care.' CONCLUSION: Healthcare professionals recognized the centrality of compassionate care during the pandemic which entailed a commitment to offering themselves, the balancing of advantages and disadvantages in order to find the best solution, as well as the need to safeguard themselves using professional competencies. Such findings can enrich the contemporary understanding of compassion, including when it is lacking. Support from the healthcare organization, the public, and leadership were crucial in fostering compassionate care in healthcare professionals during the pandemic and in moving the field forward in the future.
ABSTRACT
Background: Self-efficacy expresses a learner's perception of how well they can do in the online academic setting. Although students' academic successes can be measured by online learning self-efficacy, there is a scarcity of evidence targeted toward allied health students. Objective: The primary aim of this study is to determine the level of online self-efficacy among students from skill-based allied health programs. The secondary aim is to correlate online self-efficacy with age, sex, year level, and program of the students. Methods: This cross-sectional analytic study utilized the Online Learning Self-Efficacy Scale (OLSE) to determine students' level of self-efficacy via a survey conducted with students who underwent the Enriched Virtual Mode of learning. Descriptive statistics was used to characterize the study participants, describe the level of self-efficacy, and compare the subscales of OLSE. Inferential statistics using Spearman's rho was performed to determine the correlation. Results: A total of 117 respondents with a mean age ± SD of 20.59 ± 0.11 years old, predominantly female (71%) were included in the study. The students from allied health programs had an online self-efficacy overall mean score of 3.83 (SD=0.05; range 2.64-5.00) with the use of technology subscales weighted the highest mean score (4.24). Females have a higher average OLSE score (M=3.92, SD=0.05) compared to males. Significant correlation was found between OLSE scores to sex (r=0.260, p=0.005) and year level (r=-0.199, p=0.031) while nonsignificant correlation was found between OLSE scores to the program (r=-0.048, p=0.604) and age (r=-0.123, p=0.185). Conclusion: Students of allied health programs generally have a very good level of online self-efficacy. This study assists educators in developing proactive strategies and approaches to promote students' self-confidence across all domains and encourage them to adopt a dynamic remote learning-based approach. Educational institutions should use this opportunity to assess how well they have implemented remote learning to ensure educational continuity, especially in times of crisis.
ABSTRACT
INTRODUCTION: The US Food and Drug Administration is poised to restrict the availability of menthol cigarettes and flavored cigars, products disproportionately used by Black/African American (B/AA) individuals. We examined B/AA youth and adult perceptions regarding factors contributing to tobacco use, as well as prevention/cessation resources. METHODS: In 2 mixed-methods studies in Richmond, Virginia, we conducted cross-sectional surveys among youth (n = 201) and adult (n = 212) individuals who were primarily B/AA and reported past 30-day cigar smoking or nontobacco use, followed by focus groups with a subset (youth: n = 30; adults: n = 24). Focus groups were analyzed using a thematic analysis framework, and descriptive survey data provided context to themes. RESULTS: Among focus group participants, 20% of youth and 75% of adults reported current cigar smoking. Six themes emerged across the groups: advertising/brands, sensory experiences, costs, social factors, youth-related factors, and dependence/cessation. Youth and adults perceived cigars as popular; cigar use was attributed to targeted advertising, flavors, affordability, and accessibility. While adults expressed concern regarding youth tobacco use, youth did not perceive tobacco prevention programs as helpful. Adults and youth reported limited access to community tobacco prevention/cessation programs. DISCUSSION: Expanded tobacco prevention and cessation resources for B/AA people who smoke could leverage federal regulatory actions to ban tobacco products targeted toward this group and decrease disparities in tobacco-related morbidity and mortality.

BACKGROUND: Multiple short delirium detection tools have been validated in research studies and implemented in routine care, but there has been little study of these tools in real-world conditions. This systematic review synthesized literature reporting completion rates and/or delirium positive score rates of detection tools in large clinical populations in general hospital settings. METHODS: PROSPERO (CRD42022385166). Medline, Embase, PsycINFO, CINAHL, and gray literature were searched from 1980 to December 31, 2022. Included studies or audit reports used a validated delirium detection tool performed directly with the patient as part of routine care in large clinical populations (n ≥ 1000) within a general acute hospital setting. Narrative synthesis was performed. RESULTS: Twenty-two research studies and four audit reports were included. Tools used alone or in combination were the Confusion Assessment Method (CAM), 4 'A's Test (4AT), Delirium Observation Screening Scale (DOSS), Brief CAM (bCAM), Nursing Delirium Screening Scale (NuDESC), and Intensive Care Delirium Screening Checklist (ICDSC). Populations and settings varied and tools were used at different stages and frequencies in the patient journey, including on admission only; inpatient, daily or more frequently; on admission and as inpatient; inpatient post-operatively. Tool completion rates ranged from 19% to 100%. Admission positive score rates ranged from: CAM 8%-51%; 4AT 13%-20%. Inpatient positive score rates ranged from: CAM 2%-20%, DOSS 6%-42%, and NuDESC 5-13%. Postoperative positive score rates were 21% and 28% (4AT). All but two studies had moderate-high risk of bias. CONCLUSIONS: This systematic review of delirium detection tool implementation in large acute patient populations found clinically important variability in tool completion rates, and in delirium positive score rates relative to expected delirium prevalence. This study highlights a need for greater reporting and analysis of relevant healthcare systems data. This is vital to advance understanding of effective delirium detection in routine care.

Reductions in nonresidential water demand during the COVID-19 pandemic highlighted the importance of understanding how water age impacts drinking water quality and microbiota in piped distribution systems. Using benchtop model distribution systems, we aimed to characterize the impacts of elevated water age on microbiota in bulk water and pipe wall biofilms. Five replicate constant-flow reactors were fed with municipal chloraminated tap water for 6 months prior to building closures and 7 months after. After building closures, chloramine levels entering the reactors dropped; in the reactor bulk water and biofilms the mean cell counts and ATP concentrations increased over an order of magnitude while the detection of opportunistic pathogens remained low. Water age, and the corresponding physicochemical changes, strongly influenced microbial abundance and community composition. Differential initial microbial colonization also had a lasting influence on microbial communities in each reactor (i.e., historical contingency).

Brucella abortus causes infections in humans and livestock. Bacterial isolates are challenging to obtain, and very little is known about the genomic epidemiology of this species in Africa. Here, we report the complete genome sequence of a Brucella abortus isolate cultured from a febrile human in northern Tanzania.
ABSTRACT
We examine whether cigarettes serve as substitutes for electronic nicotine delivery systems (ENDS) among ENDS users and demonstrate methodological extensions of data from a cross-price purchase task to inform policies and interventions. During a clinical laboratory study, n = 19 exclusive ENDS users and n = 17 dual cigarette/ENDS users completed a cross-price purchase task with cigarettes available at a fixed price while prices of own-brand ENDS increased. We estimated cross-price elasticity using linear models to examine substitutability. We defined five additional outcomes: nonzero cross-price intensity (purchasing cigarettes if ENDS were free), constant null demand (not purchasing cigarettes at any ENDS price), cross-product crossover point (first price where participants purchased more cigarettes than ENDS), dual-demand score (percentage of prices where both products were purchased), and dual-use break point (minimum relative price to force complete substitution). The cross-price elasticity results indicated that cigarettes could serve as substitutes for ENDS among ENDS users on average, but this average effect masked substantial heterogeneity in profiles of demand (here, a measure of the drug's reinforcement potential). Policies and regulations that increase ENDS prices appear unlikely to steer most exclusive ENDS users toward cigarette use, as most would not purchase cigarettes at any ENDS price, but they could prompt some dual users to substitute cigarettes completely while others remain dual users. This heterogeneity in consumer responses suggests additional indices of cross-product demand are useful to characterize the anticipated and unanticipated effects of tobacco price policies more fully.
