RESUMEN

OBJECTIVE: Mobile health (mHealth), defined as the use of mobile phones or applications in healthcare, has been developed to enhance asthma care; yet implementation is inconsistent, and few studies have focused on provider perspectives on use in daily practice. The purpose of this study was to explore primary care pediatric provider perspectives regarding mHealth use in clinical practice for children with asthma. METHODS: A qualitative, descriptive approach was utilized to perform semi-structured interviews on asthma mHealth use with providers caring for children with asthma. Interview transcripts were coded by two independent investigators and any differences were reconciled. Interviews continued until thematic saturation was achieved. RESULTS AND CONCLUSIONS: Seventeen pediatric providers were recruited and interviewed. Three themes identified included implementation benefits, implementation barriers, and reporting desires, with 11 subthemes. Many subthemes were consistent across providers (e.g. self-management benefits and electronic medical record integration), while others such as provider clinical burden and approach to integrating mHealth data reports into daily workflow demonstrated variability. Provider perspectives highlight the potential of mHealth applications in asthma self-management while offering challenges related to clinical burden and suggestions for reporting and workflow integration. These results provide valuable perspectives on mHealth use and reporting to ensure provider efficiency and technology-enhanced asthma care. This study investigates pediatric provider perspectives on asthma mobile health use and reporting in daily practice, a topic that has not sufficiently been explored within the literature. Results can guide best practices, encourage more consistent use, and maximize the benefits of asthma mHealth tools by providers.

RESUMEN

PURPOSE: To assess the association between food insecurity and colorectal cancer screening uptake in screening eligible participants in New York State. METHODS: We analyzed 28,154 adults who participated in New York State Behavioral Risk Factor Surveillance System (BRFSS) from 2018 to 2021, were age-eligible for colorectal cancer screening based on the USPSTF guidelines at the time of survey administration and answered a version of the administered survey that included the module on food insecurity. Participants were defined as food insecure if they self-reported being always, usually, or sometimes stressed about having enough money to buy nutritious meals in the past 12 months. We compared demographic, healthcare access, overall health status, food insecurity by colorectal cancer screening status. Multivariable analyses were performed to assess the association of food insecurity and colorectal cancer screening status after adjusting for relevant covariates. Weighted analyses were performed using survey procedures to obtain population estimates. RESULTS: Food insecurity was statistically significantly associated a decreased likelihood of being up to date on colorectal cancer screening (ORadj 0.83, 95% CI [0.72, 0.94]) and being ever screened for colorectal cancer (ORadj 0.74, 95% CI [0.64, 0.87]) after adjusting for overall health status, healthcare coverage, interview year, age, race/ethnicity, sex, educational attainment, and income. Health status, health coverage, age, and Non-Hispanic Black race/ethnicity showed positive, statistically significant association with ever being screened and with being up to date for colorectal cancer screening. Lower income, lower educational attainment, and non-Hispanic Asian race/ethnicity were statistically significant inverse predictors of ever being screened and being up to date on screening. CONCLUSION: This project assessed the association between food insecurity and colorectal cancer screening uptake using the BRFSS survey. Food insecurity may be an important predictor for colorectal cancer screening uptake in eligible adults in the United States. The results from the study can inform future interventions and policies designed to improve participation in routine colorectal cancer screening.

RESUMEN

The emergence of plasmid-mediated resistance threatens the efficacy of polymyxins as the last line of defense against pan-drug-resistant infections. However, we have found that using Mueller-Hinton II (MHII), the standard minimum inhibitory concentration (MIC) medium, results in MIC data that are disconnected from in vivo treatment outcomes. We found that culturing putative colistin-resistant Acinetobacter baumannii clinical isolates, as defined by MICs of >2 mg/L in standard MHII testing conditions, in bicarbonate-containing media reduced MICs to the susceptible range by preventing colistin resistance-conferring lipopolysaccharide modifications from occurring. Furthermore, the lower MICs in bicarbonate-containing media accurately predicted in vivo efficacy of a human-simulated dosing strategy of colistin and polymyxin B in a lethal murine infection model for some polymyxin-resistant A. baumannii strains. Thus, current polymyxin susceptibility testing methods overestimate the contribution of polymyxin resistance-conferring mutations and incorrectly predict antibiotic activity in vivo. Polymyxins may remain a viable therapeutic option against Acinetobacter baumannii strains heretofore determined to be "pan-resistant."

RESUMEN

Current assessment protocols for attention-deficit/hyperactivity disorder (ADHD) focus heavily on a set of highly overlapping symptoms, with well-validated factors like cognitive disengagement syndrome (CDS), executive function (EF), age, sex, and race and ethnicity generally being ignored. Using machine learning techniques, the current study aimed to validate recent findings proposing a subset of ADHD symptoms that, together, predict ADHD diagnosis, severity, and impairment level better than the full symptom list, while also testing whether the inclusion of the factors listed above could further increase accuracy. Parents of 1,922 children (50.1% male) aged 6-17 years completed rating scales of ADHD, CDS, EF, and impairment. Results suggested nine symptoms as most important in predicting outcomes: (a) has difficulty sustaining attention in tasks or play activities; (b) does not follow through on instructions and fails to finish work; (c) avoids tasks (e.g., schoolwork, homework) that require sustained mental effort; (d) is often easily distracted; (e) has difficulty organizing tasks and activities; (f) is often forgetful in daily activities; (g) fidgets with hands or feet or squirms in seat; (h) interrupts/intrudes on others; and (i) shifts around excessively or feels restless or hemmed in. The abbreviated algorithm achieved accuracy rates that did not significantly differ compared to an algorithm comprising all 18 symptoms in predicting impairment, while also demonstrating excellent discriminative ability in predicting ADHD diagnosis. Adding CDS and EF to the abbreviated algorithm further improved the prediction of global impairment. Continued refinement of screening tools will be key to ensuring access to clinical services for youth at risk for ADHD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMEN

Due to the pervasive use of oil for energy and other industrial applications, solutions to oil-water separation have received a great deal of attention lately to address the environmental damage of oil spills and groundwater contamination. However, many of these separation methods are materially expensive and environmentally hazardous, require elaborate fabrication, or rely on large amounts of energy to function. Herein, we provide an effective low-cost method for oil-water separation based on the hydrophobicity induced by self-assembled bioinspired diphenylalanine peptide nanowires grown on polyester fabric. This modified polyester fabric mesh exhibits parahydrophobicity and oleophilicity due to the hierarchical nano-to-microscale surface roughness. This mesh also achieves consistent high water separation efficiencies of over 99% and an ultrahigh oil flux of up to 26.7 ± 5 kLm-2·h-1. The growth of bioinspired peptide-based nanostructures on fabrics using facile technique and their application in oil-water separation presents the potential for using bioinspired materials for environmental remediation while minimizing environmental footprint.

RESUMEN

Freshwater crayfish are vital species in ecosystems where they naturally occur, as they hold keystone and ecological engineering positions in these systems. Non-native species are common and widely spread throughout Earth's freshwater ecosystems and can have severe impacts on native crayfish populations. There has yet to be a comprehensive global review of the impacts of non-native species on native crayfish. Two literature searches were conducted using Web of Science and Google Scholar to find articles to address four key aims: (1) summarise trends in the literature; (2) examine the mechanisms by which invasive crayfish impact native crayfish species; (3) examine the mechanisms by which other non-native species, such as fish, impact native crayfish species; and (4) identify gaps in knowledge and research priorities. This review highlights that a far greater amount of research has addressed the effects of invasive crayfish than other non-native species. The research on invasive crayfish focuses on four types of interactions with native crayfish: competition, predation, introduction of disease, and reproductive impacts. Studies addressing the impacts of other non-native species on crayfish indicate that predation and habitat destruction by these species are the key processes impacting native crayfish. It is evident that field-based research, particularly concerning competition between invasive and native crayfish, is limited. Therefore, further in situ research is needed to assess the validity of laboratory results in a natural setting. Additionally, in many cases, the impact of certain non-native species on native crayfish populations has gone unmonitored. For this reason, it is recommended that additional research focus on assessing the impact of these non-native species. To conclude, the impacts of invasive crayfish on native crayfish are profound and wide-ranging, often leading to population decline or extirpation. Further, other non-native species are also likely to have a highly deleterious impact on native crayfish populations; however, more research is required to understand the scope of this impact.

RESUMEN

OBJECTIVE: Youth living with HIV (YLHIV) in the southern United States experience poor outcomes across the HIV care continuum and are at high-risk for virologic failure. This study used a qualitative, community-engaged approach to inform the development of a tailored mobile Health (mHealth) tool for YLHIV in South Carolina (SC). METHODS: Semistructured qualitative interviews were conducted with YLHIV in SC (n = 16) and their HIV care providers (n = 15). Focus group discussions (FGDs) were also conducted with HIV-focused community-based organization staff (n = 23). Interviews and FGDs queried desired components for a future mHealth tool tailored for YLHIV. Data were analyzed using a team-based rapid qualitative approach. RESULTS: Across informants, key themes emerged related to medical management of HIV, including a desire for connections with medical providers, appointment and medication reminders, and accurate HIV information. In addition, informants voiced a desire for mental health resources to be integrated into the app. Connection with HIV-positive peers also emerged as a key desire from youth informants. In terms of app design, informants emphasized the need for strict privacy practices, a youth-friendly design, compensation for use, and integration with existing healthcare systems. CONCLUSIONS: mHealth interventions developed for YLHIV should meet the mental health and social needs of YLHIV in addition to their medical needs. In addition, the highly stigmatized nature of HIV requires careful consideration when designing digital tools-youth want their privacy prioritized, but also express strong desire for social support to help cope with the isolation and stigma of this chronic health condition.

RESUMEN

The purpose of this study was to examine how demographics, etiology, and clinical examination findings are related to visual outcomes in subjects with open globe injury (OGI) across a large and generalizable sample. A retrospective cohort analysis was performed using data collected from the electronic medical records of four tertiary university centers for subjects with OGI presenting from 2018 to 2021. Demographic information, injury mechanisms, clinical exam findings, visual acuity (VA) at presentation and most recent follow-up were recorded. In subjects with bilateral OGIs, only right eyes were included. A modified ocular trauma score (OTS) using presenting VA, the presence of perforating injury, OGI, and afferent pupillary defect was calculated. The risk of subjects' demographic characteristics, ocular trauma etiology, clinical findings and modified OTS on the presence of monocular blindness at follow-up were assessed using univariable and multivariable regression models. 1426 eyes were identified. The mean age was 48.3 years (SD: ± 22.4 years) and the majority of subjects were men (N = 1069, 75.0%). Univariable analysis demonstrated that subjects of Black race were 66% (OR: 1.66 [1.25-2.20]; P < 0.001) more likely to have monocular blindness relative to White race at follow-up. OTS Class 1 was the strongest predictor of blindness (OR: 38.35 [21.33-68.93]; P < 0.001). Based on multivariable analysis, lower OTS category (OTS Class 1 OR: 23.88 [16.44-45.85]; P < 0.001) moderately predicted visual outcomes (R2 = 0.275, P < 0.001). OGI has many risks of poor visual outcome across patient groups that vary by demographic category, mechanism of injury, and clinical presentation. Our findings validate that a modified OTS remains a strong predictor of visual prognosis following OGI in a large and generalizable sample.

RESUMEN

Individuals with chronic obstructive pulmonary disease (COPD) experience high symptom burden, severe illness, and frequent deterioration in quality of life. Women with COPD represent a unique population with potential unmet care needs yet remain underrepresented in palliative care (PC) literature. The purpose of this study was to investigate specific needs of women with COPD, learn how COPD symptoms impact women, and explore factors related to PC knowledge, access, and barriers. A total of 30 individuals were enrolled in this prospective, single-arm multimethod study, using an adapted Maslow's hierarchy of needs framework. Fifteen participated in semistructured interviews. Women with advanced COPD identified care needs and barriers including access to medications/oxygen and resources (pulmonary rehabilitation/support groups), information about disease/treatment, and effect of weather conditions on symptoms. Some participants were not under the direct care of a pulmonologist but recognized the importance of their services. None of the participants had been referred to or received PC. This study provides evidence that women have unmet care needs, high symptom burden, and disease uncertainty. Women with COPD should have the opportunity to have the supportive care that PC offers. Palliative care and hospice nurses have opportunities to address unmet care needs, increased symptom burden, and disease uncertainty.

RESUMEN

Background: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has resulted in illness, deaths and societal disruption on a global scale. Societies have implemented various control measures to reduce transmission of the virus and mitigate its impact. Individual behavioural changes are crucial to the successful implementation of these measures. One commonly recommended measure to limit risk of infection is face covering. It is important to identify those factors that can predict the uptake and maintenance of face covering. Objectives: We aimed to identify and synthesise the evidence on malleable psychological and psychosocial factors that determine uptake and adherence to face covering aimed at reducing the risk of infection or transmission of COVID-19. Search Methods: We searched various literature sources including electronic databases (Medline ALL, Child Development & Adolescent Studies, ERIC, PsycInfo, CINAHL & Web of Science), web searches, conference proceedings, government reports, other repositories of literature and grey literature. The search strategy was built around three concepts of interest including (1) context (terms relating to COVID19), (2) behaviour of interest and (3) terms related to psychological and psychosocial determinants of COVID Health-Related Behaviours and adherence or compliance with face covering, to capture malleable determines. Searches capture studies up until October 2021. Selection Criteria: Eligibility criteria included observational studies (both retrospective and prospective) and experimental studies that measure and report malleable psychological and psychosocial determinants and handwashing at an individual level, amongst the general public. Screening was supported by the Cochrane Crowd. Studies titles and abstracts were screened against the eligibility criteria by three independent screeners. Following this, all potentially relevant studies were screened at full-text level by the research team. All conflicts between screeners were resolved by discussion between the core research team. Data Collection and Analysis: All data extraction was managed in EPPI-Reviewer software. All eligible studies, identified through full-text screening were extracted by one author. We extracted data on study information, population, determinant, behaviour and effects. A second author checked data extraction on 20% of all included papers. All conflicts were discussed by the two authors until consensus was reached. We assessed methodological quality of all included studies using an adapted version of the Joanna Briggs Institute Quality appraisal tool for cross-sectional studies. Main Results: Our initial searches yielded 23,587 results, of which 23 were included in this review. The included studies were cross-sectional in design, came from nine countries and had a combined sample of 54,401 participants. The vast majority of studies had samples from the general public, with five of the studies focusing on specific samples. All included studies considered people over the age of 18. The quality of 10 of the studies was rated as unclear, 10 were rated as low, and 3 rated high risk of bias, predominately due to lack of reporting of recruitment, sample characteristics and methodology. Ten studies were included in the meta-analysis and 16 in the narrative synthesis. Findings from the meta-analysis indicated that knowledge of COVID-19 (0.341, 95% confidence interval [CI] = 0.06, 0.530, I 2 = 100%) was the malleable determinant most associated with face covering behaviour. Perceived susceptibility of COVID-19 (r = 0.088, 95% CI = -0.004, 0.180, I 2 = 80%) and COVID-related worry and anxiety (r = 0.064, 95% CI = -0.066, 0.191, I 2 = 93% had little to no effect on face covering behaviour. In the narrative synthesis, the strongest association was found between perceived benefits and effectiveness of behaviours and mask wearing behaviour. Authors' Conclusions: Understanding the effects of various malleable determinants on COVID-related face covering can aid in the development and implementation of interventions and public health campaigns to promote face covering behaviour in potential new waves of COVID-19 or other respiratory infections. Knowledge of COVID and perceived benefits of face coverings warrant further consideration in future research and policy.

RESUMEN

Background: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has resulted in illness, deaths and societal disruption on a global scale. Societies have implemented various control measures to reduce transmission of the virus and mitigate its impact. Individual behavioural changes are crucial to the successful implementation of these measures. One commonly recommended measure to limit risk of infection is frequent handwashing. It is important to identify those factors that can predict the uptake and maintenance of handwashing. Objectives: We aimed to identify and synthesise the evidence on malleable psychological and psychosocial factors that determine uptake and adherence to handwashing aimed at reducing the risk of infection or transmission of COVID-19. Search Methods: We searched various literature sources including electronic databases (Medline ALL, Child Development & Adolescent Studies, ERIC, PsycInfo, CINAHL and Web of Science), web searches, conference proceedings, government reports, other repositories of literature and grey literature.

Main Results: Our initial searches yielded 23,587 results, of which 56 studies were included in this review. The included studies were cross sectional in design, came from 22 countries and had a combined sample of 199,376 participants. The vast majority of studies had samples from the general public, with eight of the studies focusing on specific samples. All included studies considered people over the age of 18. The quality of the majority of the studies was good (n = 30 rated low risk of bias), with 8 rated high risk of bias, predominately due to lack of reporting of recruitment, sample characteristics and methodology. Thirty-four studies were included in the narrative synthesis and 28 in the meta-analysis.Findings indicated that emotions about COVID-19 (worry [0.381, confidence interval [CI] = 0.270-0.482, I 2 = 92%) and anxiety (0.308, CI = 0.154-0.448, I 2 = 91%]), knowledge of COVID-19 (0.323, CI = 0.223-0.417, I 2 = 94%), and perceived social norms (0.303, CI = 0.184-0.413, I 2 = 92%) were among the malleable determinants most associated with handwashing. Perceived severity (0.006, CI = -0.011-0.023) and susceptibility of COVID-19 (0.041, CI = -0.034 to 0.115) had little to no effect on handwashing behaviour. Authors' Conclusions: Understanding the effects of various malleable determinants on COVID-related handwashing can aid in the development and implementation of interventions and public health campaigns to promote handwashing behaviour in potential new waves of COVID-19 or other respiratory infections. Emotions about COVID, knowledge of COVID and perceived social norms warrant further consideration in future research and policy.

RESUMEN

Bordetella pertussis is a Gram-negative bacterium that is the causative agent of the respiratory disease known as pertussis. Since the switch to the acellular vaccines of DTaP and Tap, pertussis cases in the US have risen and cyclically fallen. We have observed that mRNA pertussis vaccines are immunogenic and protective in mice. Here, we further evaluated the pertussis toxoid mRNA antigen and refined the formulation based on optimal pertussis toxin neutralization in vivo. We next evaluated the mRNA pertussis vaccine in Sprague-Dawley rats using an aerosol B. pertussis challenge model paired with whole-body plethysmography to monitor coughing and respiratory function. Female Sprague-Dawley rats were primed and boosted with either commercially available vaccines (DTaP or wP-DTP), an mRNA-DTP vaccine, or mock-vaccinated. The mRNA-DTP vaccine was immunogenic in rats and induced antigen-specific IgG antibodies comparable to DTaP. Rats were then aerosol challenged with a streptomycin-resistant emerging clinical isolate D420Sm1. Bacterial burden was assessed at days 1 and 9 post-challenge, and the mRNA vaccine reduced burden equal to both DTaP and wP-DTP. Whole-body plethysmography revealed that mRNA-DTP vaccinated rats were well protected against coughing which was comparable to the non-challenged group. These data suggest that an mRNA-DTP vaccine is immunogenic in rats and provides protection against aerosolized B. pertussis challenge in Sprague-Dawley rats.

RESUMEN

Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne illness in the United States. Despite the rise in Lyme disease incidence, there is no vaccine against B. burgdorferi approved for human use. Little is known about the immune correlates of protection needed to prevent Lyme disease. In this work, a mouse model was used to characterize the immune response and compare the protection provided by two USDA-approved vaccines for use in canines: Duramune (bacterin vaccine) and Vanguard crLyme (subunit vaccine composed of two outer surface proteins, OspA and OspC). C3H/HeNCrl mice were immunized with two doses of either Duramune or Vanguard, and immune responses and protection against B. burgdorferi were assessed in short (35 days) and long-term (120 days) studies. Flow cytometry, ELISPOT detection of antibody-producing cells, and antibody affinity studies were performed to identify correlates of vaccine-mediated protection. Both vaccines induced humoral responses, with high IgG titers against B. burgdorferi. However, the levels of anti-B. burgdorferi antibodies decayed over time in Vanguard-vaccinated mice. While both vaccines triggered the production of antibodies against both OspA and OspC, antibody levels against these proteins were also lower in Vanguard-vaccinated mice 120 days post-vaccination. Both vaccines only provided partial protection against B. burgdorferi at the dose used in this model. The protection provided by Duramune was superior to Vanguard 120 days post-vaccination, and was characterized by higher antibody titers, higher abundance of long-lived plasma cells, and higher avidity antibodies than Vanguard. Overall, these studies provide insights into the importance of the humoral memory response to veterinary vaccines against Lyme disease and will help inform the development of future human vaccines.

RESUMEN

BACKGROUND: Current treatments for Tourette syndrome (TS) and persistent tic disorder (PTD) are often insufficiently effective, inaccessible, and frequently associated with adverse events. Thus, we must continue to develop and test effective, accessible, and safe treatment options. OBJECTIVE: We aimed to conduct a pilot randomized controlled trial (RCT) comparing a novel, videoconference-delivered group mindfulness-based intervention for tics (MBIT) to videoconference-delivered group psychoeducation, relaxation, and supportive therapy (PRST) for adults with TS or PTD. METHODS: Thirty-two adults with TS or PTD were randomly assigned to receive 8 weeks of either MBIT or PRST. Tic severity, tic-related impairment, and global improvement were assessed by a trained, independent evaluator who was masked to treatment condition at baseline (week 0), posttreatment (week 9), 1-month follow-up, and 6-month follow-up. All study procedures were conducted online via secure videoconferencing. RESULTS: Twenty-eight participants began treatment and were included in analyses. MBIT, relative to PRST, was associated with a significantly greater decline in tic severity (d = 0.85) and tic-related impairment (d = 0.99) from baseline to posttreatment. Treatment response was significantly higher in MBIT (69%) than in PRST (13%). Neither treatment resulted in serious adverse effects. The durability of treatment outcomes is also reported and discussed. CONCLUSIONS: The results from this pilot RCT suggest that videoconference-delivered group MBIT may be an efficacious, accessible, and safe intervention for adults with tics. Future research is necessary to confirm these preliminary findings. © 2024 The Author(s).

RESUMEN

Introduction: The objective of this study was to determine the sensitivity of brain magnetic resonance imaging (MRI) in the detection of choroidal metastasis (CM) from systemic primary cancers. Methods: A retrospective chart review identified patients with clinically confirmed CM seen on the Oncology Service (Byers Eye Institute) between January 2018 and March 2022. Patients had an MRI brain and/or orbits performed within 3 months of CM diagnosis. Evaluation of CM detection by MRI was then divided into two parts: an initial "standard read," where determination of CM detection was based solely on the original radiology report, to reflect real-world performance, and a subsequent "dedicated read," for which a board-certified neuroradiologist, blinded to the laterality and location of the CM, reevaluated the studies to provide an objective "gold standard" interpretation regarding the radiographic detection of CM. Results: The study included 42 eyes of 40 patients with confirmed CM. On standard read, MRI detection of CM occurred in 21 of 42 eyes (50%), with no significant difference between MRI brain and orbit protocols (p = 0.249). Features associated with improved detection were increased tumor basal diameter (p < 0.001) and ultrasonographic tumor thickness (p = 0.003). On dedicated read, MRI detection of CM improved to 26 of 33 eyes (76%; limited to eyes with full complement of pre- and post-gadolinium sequences). Post-gadolinium 3D fluid-attenuated inversion recovery (FLAIR) sequence with fat suppression was the most sensitive (88%) for CM detection. 42% and 58% of lesions were visualized using conventional pre-gadolinium T1- and T2-weighted imaging, respectively. Conclusions: MRI sensitivity to detect CM improved from 50% to 76% with focused reinterpretation. Increased utilization of the post-gadolinium 3D FLAIR sequence and increased ocular scrutiny in cancer patients undergoing brain imaging may facilitate earlier diagnosis of CM.

RESUMEN

Cancer screenings aid in the early detection of cancer and can help reduce cancer-related mortality. The current model of care for cancer screening is often siloed, based on the targeted cancer site. We tested the acceptability of a new model of care, called the One-Stop-Shop Cancer Screening Clinic, that centralizes cancer screenings and offers patients the option to complete all their recommended cancer screenings within one to two visits. We administered surveys to 59 community members and 26 healthcare providers to gather feedback about the One-Stop-Shop model of care. Both community members and providers identified potential benefits (e.g., decreased patient burden, increased completion of cancer screenings) and also potential challenges (e.g., challenges with workflow and timing of care) of the model of care. The results of the study support the acceptability of the model of care. Of the community members surveyed, 89.5% said, if offered, they would be interested in participating in the One-Stop-Shop Cancer Screening Clinic. Future studies are needed to formally evaluate the impact and cost effectiveness of the One-Stop-Shop Cancer Screening Clinic.

RESUMEN

PIWI-interacting RNAs (piRNAs) are 24-32 nucleotide RNA sequences primarily expressed in germ cells and developing embryos that suppress transposable element expression to protect genomic integrity during epigenetic reprogramming events. We characterized the expression of piRNA sequences and their encoding clusters in sperm samples from an idiopathic fertility model of Holstein bulls with high and low Sire Conception Rates. The piRNA populations were determined to be mostly similar between fertility conditions when investigated by principal component and differential expression analysis, suggesting that a high degree of conservation in the piRNA system is likely necessary for the production of viable sperm. Both fertility conditions demonstrated evidence of 'ping-pong' activity - a secondary biogenesis pathway associated with active transposable element targeting and suppression. Most sperm-borne piRNAs were between 29-30 nucleotides in length and originated from 226 clusters across the genome, with the exception of chromosome 20. Mapping analysis revealed abundant targeting of several transposable element families, suggesting a suppressive function of sperm piRNAs consistent with their established roles. Expression of genes targeted by sperm-borne piRNAs is significantly reduced throughout early embryogenesis compared to the mRNA population. Limited transposable element expression is known to be essential for spermatogenesis, thus epigenetic regulation of this pathway is likely to influence sperm quality and fertilizing capacity.

RESUMEN

Dyspnea is the most common and activity-limiting symptom for those with chronic obstructive pulmonary disease (COPD). Treatment is complex, palliative care (PC) dyspnea relief interventions are poorly understood, and PC remains underutilized in COPD despite national guidelines and recommendations. The purpose of this rapid review was to explore the concept of dyspnea and role of PC through the lens of providers, caregivers, and patients with COPD. A systematic approach for synthesis was used to identify 13 articles published between January 2018 and October 2023. Team members compared data via visualization and theme clustering to identify key conclusions describing operationalization of dyspnea, management, and PC implications. Dyspnea operationalization was challenging, with inconsistent measurement and terminology. Dyspnea was a significant burden in COPD and contributed to complexity of treatment. Opioids were used most often to treat dyspnea, but provider perspectives and biases can influence treatment decisions and perceptions of opioid therapy by the patient and caregiver. Evidence-based clinical practice guidelines and policies are needed to clarify the use of opioid therapy for dyspnea management to reduce stigmatization and barriers to treatment. Provider education should emphasize a multipronged approach to treatment of dyspnea in COPD with integration of PC early in the care continuum.

RESUMEN

BACKGROUND: Provider burnout is a work-related syndrome that is under-recognized, under-reported, and has negative repercussions on the individual, system, and patients. This study investigated burnout incidence and its association with wellness characteristics such as resilience, psychological safety, and perceptions of the workplace to inform future work in improving well-being. METHODS: Electronic surveys were sent to 153 physicians and advanced practice providers (APPs) in the department of surgery at a single institution. Survey topics included demographics, intention to stay, engagement, and items from validated measures for workplace perceptions including work pace/stress (Mini Z), burnout, psychological safety, and resilience. Descriptive statistics, bivariate associations, and logistic regression were used to evaluate responses. RESULTS: Overall response rate was 47%. The majority of providers reported feeling burned out (56%), and 48% indicated they would probably leave the organization within three years. Additionally, 61% reported being satisfied with their job and 55% felt that they contributed professionally in the ways they value most (meaningful work/engagement). Significant predictors for burnout included negative work environment perceptions (work pace/stress), low resilience, low meaningful work, and professional role (physician vs APP). DISCUSSION: Maintaining a healthy workforce requires investigation into the factors that support workplace well-being. The strongest predictors of burnout were work pace/stress. Protective factors against burnout were psychological safety and resilience. An organizational culture that promotes psychological safety, as well as workplace improvements to enhance providers' sense of meaning in work, and decreasing work pace and stress may contribute to the prevention of burnout and the retention.
