RESUMEN
BACKGROUND: Physical activity can improve cognition; however, little is known regarding the relationships between longitudinal objectively-measured physical activity, cognition, and inflammation in older breast cancer survivors. METHODS: Older (≥60 yrs) breast cancer survivors (n = 216) and frequency-matched non-cancer controls (n = 216) were assessed at baseline (pre-systemic therapy for survivors) and annually for up to five years. Assessments included hip-worn ActiGraphs worn for seven days, neuropsychological tests, the Functional Assessment of Cancer Therapy-Cognitive Function Perceived Cognitive Impairment (FACT-Cog PCI) subscale, and circulating levels of C-reactive protein (CRP) and interleukin-6 (IL-6). Data were analyzed using linear mixed-effect, random-effect contemporaneous fluctuation, and multi-level mediation models, considering covariates; p < .05 (two-sided) was considered significant. RESULTS: Survivors had fewer minutes of moderate-to-vigorous physical activity (MVPA) than controls at 36-, 48-, and 60-month time points (p < .03). Fewer survivors met Aerobic Physical Activity Guidelines at 36 months than controls (17.7% vs 33.0%, p = .030). When Guidelines were met (vs not), FACT-Cog PCI scores were 2.1 ± 1.0 (p = .034) points higher. Higher MVPA and meeting Aerobic Guidelines were not related to objective neuropsychological performance. MVPA was inversely associated with CRP and IL-6 (p < .001), but inflammation did not mediate physical activity effects on perceived cognition. CONCLUSIONS: Older breast cancer survivors were less physically active than older non-cancer controls, especially farther from baseline. Meeting Aerobic Guidelines was associated with better perceived cognition in survivors. Survivorship care should consider physical activity monitoring and referral to rehabilitation and supervised exercise programs to promote physical activity and improve recovery in older survivors.
RESUMEN
Importance: In Medicare Advantage (MA), step therapy for physician-administered drugs is an approach to lowering drug spending. The impact of step therapy in MA on prescribing behavior and the magnitude of any changes has not been analyzed. Objective: To evaluate the impact of step therapy on macular degeneration drug prescribing patterns for 3 large MA insurers. Design, Setting, and Participants: This was a retrospective encounter-based analysis using 20% nationally representative MA outpatient and carrier encounter records for 2017 to 2019. Participants were MA beneficiaries who were 65 years or older and had received a macular degeneration drug administration. Macular degeneration drug administrations for beneficiaries of MA Aetna, Humana, and UnitedHealthcare (UHC) insurers were assessed. Humana implemented macular degeneration step therapy in 2019, setting bevacizumab as the plan-preferred drug, and aflibercept and ranibizumab as the plan-nonpreferred drugs. Aetna and UHC, which did not implement macular degeneration step therapy, served as the control group. Data analyses were performed from May 2024 to December 2024. Exposures: A macular degeneration drug administration subject to a step therapy policy. Main Outcome and Measures: A binary indicator of whether the drug administered was bevacizumab. Linear probability models and a difference-in-differences framework were used to quantify changes in prescribing patterns before and after the introduction of step therapy for MA insurers that did and did not implement step therapy. To empirically measure the impact of step therapy, the first administration of a treatment episode was assessed, followed by switching patterns. Results: A total of 18â¯331 MA beneficiaries, 21â¯683 treatment episodes, and 171â¯985 drug administrations were included across the control and treatment groups. The difference-in-differences regressions found a 7.8% (95% CI, 4.9%-10.7%; P < .001) greater probability of being prescribed bevacizumab for the first administration due to step therapy. The predicted probabilities of preferred-drug administration in the treatment group increased from 0.61 to 0.70 between the periods before and after step therapy implementation for the first administration. Step therapy was not significantly associated with an increased rate of medication switching (hazard ratio, 0.86; 95% CI, 0.71-1.06; P = .15). Conclusions and Relevance: The findings of this retrospective encounter-based analysis indicate that step therapy is associated with a greater probability of prescribing the plan-preferred drug for the first administration. The analysis failed to find a statistically significant greater rate of medication switching within a treatment episode. Step therapy changed macular degeneration prescribing patterns, but step therapy alone did not transition all administrations to the plan-preferred drug.

PURPOSE: While meibomian gland dysfunction (MGD) is widely recognized as a major cause of evaporative dry eye disease, little is known about normal gland differentiation and lipid synthesis or the mechanism underlying gland atrophy and abnormal lipid secretion. The purpose of this study was to use single-cell and spatial transcriptomics to probe changes in cell composition, differentiation, and gene expression associated with two murine models of MGD: age-related gland atrophy in wild-type mice and altered meibum quality in acyl-CoA wax alcohol acyltransferase 2 (Awat2) knockout (KO) mice. METHODS: Young (6 month) and old (22 month) wild type, C57Bl/6 mice and young (3 month) and old (13 month) Awat2 KO mice were used in these studies. For single-cell analysis, the tarsal plate was dissected from the upper and lower eyelids, and single cells isolated and submitted to the UCI Genomic Core, while for the spatial analysis frozen tissue sections were shipped to Resolve Biosciences on dry ice and sections probed in duplicate using a meibomian gland specific, 100 gene Molecular Chartography panel. RESULTS: Analysis of gene expression patterns identified the stratified expression of lipogenic genes during meibocyte differentiation, which may control the progressive synthesis of meibum lipids; an age-related decrease in meibocytes; and increased immune cell infiltration. Additionally, we detected unique immune cell populations in the Awat2 KO mouse suggesting activation of psoriasis-like, inflammatory pathways perhaps caused by ductal dilation and hyperplasia. CONCLUSION: Together these findings support novel mechanism controlling gland function and dysfunction.
RESUMEN
BACKGROUND: Many adults aged 60 years or older have functional limitations and require home and community-based services (HCBS) to support their independence and delay the transition to an institutionalized setting. This systematic review provides an evidence map of the existing literature on HCBS identifying evidence gaps for policy and research. METHODS: A comprehensive literature search of multiple databases including Medline, Embase, and Scopus was conducted through December 7, 2023. Interviews with various stakeholders were conducted to solicit additional perspectives. Narrative and thematic synthesis was conducted to evaluate HCBS in terms of populations, interventions, outcomes, person-centeredness, and relevant quality measures. RESULTS: We identified 27 primary studies and 29 quality measures. Populations of HCBS studies can be categorized as those with functional disability, cognitive impairment, high-risk/frail conditions, and disease-specific conditions (Parkinson's disease, Alzheimer's disease, and post-stroke). HCBS interventions targeted optimization of person-centered planning, nonpharmacological approaches for dementia care, physical rehabilitation, self-directed home care, geriatric resources for practical support at home, and interdisciplinary care coordination for high-risk conditions. Person-centered planning and self-direction of HCBS services were not explicitly described in many studies and very few studies focused on addressing health-related social needs, whereas the majority reported primary clinical outcomes. Numerous quality measures exist for HCBS, some of which were validated, addressed multiple person-centered domains, and may apply across various conditions and populations. Key challenges in the literature on HCBS include limited number of randomized trials, inadequate descriptions of interventions to determine person-centeredness, limited information on facilitators and barriers, and limited information on workforce challenges in recruiting, retaining, and training personnel delivering HCBS. DISCUSSION: This evidence map describes the current state of HCBS and identifies evidence gaps for future research and policy decisions.
RESUMEN
INTRODUCTION: Breast cancer treatment patterns and quality of care among patients experiencing incarceration are underexplored. This study examined associations between incarceration and breast cancer disease and treatment characteristics. METHODS: This retrospective analysis was conducted at a tertiary center in the Southeastern United States that serves as the state's safety-net hospital and primary referral site for the state's prisons. All patients ≥18 years diagnosed with breast cancer between 4/14/2014-12/30/2020 were included. Incarceration status was determined through electronic health record review. Linear regression was used to estimate the association of incarceration with time to treatment. Unadjusted overall survival (OS) was estimated using the Kaplan-Meier method with log-rank tests to compare groups. RESULTS: Of the 4329 patients included, 30 (0.7%) were incarcerated at the time of diagnosis or treatment (DI) and 4299 (99.3%) had no incarceration history (NI). Compared to patients who were NI, patients who were DI were younger (p < 0.001), more likely to be unmarried (p < 0.001), and more likely to have family history of breast cancer (p = 0.02). Patients who were DI had an increased time from diagnosis to neoadjuvant chemotherapy (+47.2 days on average, 95% CI 3.9-90.5, p = 0.03) and from diagnosis to surgery (+20 days on average, 95% CI 6.5-33.5, p = 0.02) compared to NI patients. No difference in OS was observed (log-rank p = 0.70). CONCLUSIONS: Patients who are incarcerated experienced significant delays in breast cancer care. While no differences in mortality were appreciated, these findings are concerning, as they indicate poorer care coordination for patients who are incarcerated. Further research is necessary to understand the full scope of these disparities and elucidate factors that contribute to them.

INTRODUCTION: To evaluate the effects of oral contraceptive (OC) and hormonal intrauterine device (H-IUD) use, compared to an eumenorrheic (EUM) cycle, on maximal strength and power between hormone phases. METHODS: One repetition max (1RM) leg press and bench press, peak force (PF) from knee extension and upright row isometric dynamometry, and power from vertical jump height (VJH) and reactive strength index (RSI; cm/s) were measured in 60 healthy, active women (mean ± standard deviation [SD]; Age: 26.5 ± 7.0 yrs, BMI: 22.5 ± 3.7 kg/m2) who were monophasic OC users for ≥6 months (n = 21), had a H-IUD for ≥6 months (n = 20), or had regularly naturally occurring menstrual cycle for ≥3 months or were using a non-hormonal IUD (EUM; n = 19). Participants were randomly assigned to begin in the follicular phase/placebo pill (low hormone phase; LHP) or in the luteal phase/active pill (high hormone phase; HHP) and were tested once in each phase. Estimates of total lean mass (LM), leg LM, and arm LM were measured via dual energy x-ray absorptiometry. Separate univariate ANCOVAs were used to assess the change from HHP to LHP between groups, with LM and progesterone as covariates. RESULTS: Leg press 1RM was significantly different across phases between groups (p = 0.027), with higher leg press 1RM in the HHP for the OC group (mean difference[∆HHP-LHP] ± standard error: ∆7.4 ± 15.9 kg; p = 0.043) compared to the H-IUD group (∆-8.9 ± 23.8 kg; p = 0.043). All groups demonstrated similar bench press 1RM, PF, VJH, and RSI between phases (p > 0.05). CONCLUSIONS: Lower body strength was greater in the HHP for OC users (5.6% increase) suggesting lower body maximal strength outcomes may be influenced by hormonal contraception type.
RESUMEN
BACKGROUND: Solid organ transplantation (SOT) offers improved long-term survival for youth with end-stage organ disease. From a neurodevelopmental, cognitive, and academic perspective, children with solid organ transplant have a number of unique risk factors. While cognitive functioning may improve post-transplantation, it is important to understand the trajectory of neurocognitive development starting in transplant candidacy to evaluate the implications of early deficits. AIM: The aim of this paper is to describe the neurocognitive risks and long-term implications for adolescent transplant recipients. METHOD: This paper provides an overview of neurocognitive functioning in youth with end-stage organ dysfunction with discussion of implications for adolescent transplant recipients. RESULTS: Post-transplant, adolescent, and young adult solid organ transplant recipients exhibit significant levels of executive dysfunction, with implications for decision-making, regimen adherence, and transition to adult transplant care. CONCLUSION: Transplantation may reduce the risk for poor long-term neurocognitive effects, yet adolescent transplant recipients remain at increased risk, particularly in executive functioning, which has implications for adherence and transition to adulthood. Baseline and follow-up assessments for youth with end-stage organ disease and transplant are important for the monitoring of neurocognitive development and may be used to mitigate risk for low adherence to post-transplantation treatment regimens and reduce barriers to transitioning to adult transplant care.

Chronic hepatitis B (CHB) is the leading cause of hepatocellular carcinoma (HCC) globally. We described and evaluated the outcomes of patients with CHB-HCC in Canada. In this retrospective cross-sectional cohort study, data were analysed from CHB mono-infected subjects seen between 1 January 2012 and 31 December 2022, and entered the Canadian Hepatitis B Network Registry. Descriptive analysis and chi-squared modelling were used to compare cohorts, followed by multivariable survival analysis regarding survival post-diagnosis. Statistical analyses were completed in R version 2.2. Of the 6711 patients with CHB who met inclusion criteria, 232 (3.5%) developed HCC. Compared with the CHB cohort, the majority of CHB-HCC cohort were male, SEA and HBeAg negative and born in endemic area (80% vs. 56%, 73% vs. 55%, 84% vs. 54%, 64% vs. 40% and all p < 0001). Overall, median HBV DNA level was log 2.54 (IQR: 0-4.04). Advanced liver disease, defined as minimum Fibrosis stage F3, was seen in 9.4% of overall cohort, but 92% of HCC cohort. At diagnosis, median tumour size was 2.5 cm (IQR: 1.7-4.0) and mean tumour number was 1.33 (SD: 1.33), with 81% of patients BCLC 0-A. Fifty-three per cent of patients were diagnosed with HCC as part of surveillance protocols. The survival rate after HCC diagnosis was 78.7%, during the median follow-up of 52.9 months (IQR: 17-90). In multivariable analysis, survival was significantly correlated with diagnosis through the screening programme. In this large cohort of patients with CHB-HCC, the majority of patients were detected with early-stage HCC and received treatment with curative intent, resulting in strong survival rates.
RESUMEN
Nearly all patients with type 1 diabetes and 20-30 percent of patients with type 2 diabetes use insulin to manage glycemic control. Approximately one-quarter of patients who use insulin report underuse because of cost. In response, more than twenty states have implemented monthly caps on insulin out-of-pocket spending, ranging from $25 to $100. Using a difference-in-differences approach, this study evaluated whether state-level caps on insulin out-of-pocket spending change insulin usage among commercially insured enrollees. The study included 33,134 people ages 18-64 who had type 1 diabetes or who used insulin to manage type 2 diabetes with commercial insurance coverage that was subject to state-level oversight and was included in the 25 percent sample of the IQVIA PharMetrics database during 2018-21. Insulin out-of-pocket caps did not significantly increase quarterly insulin claims for enrollees who had type 1 diabetes or who used insulin to manage type 2 diabetes. State-level caps on insulin out-of-pocket spending for commercial enrollees did not significantly increase insulin use; that may be in part because of out-of-pocket expenses being lower than cap amounts.

Experience plays a pivotal role in determining our food preferences. Consuming food generates odor-taste associations that shape our perceptual judgements of chemosensory stimuli, such as their intensity, familiarity, and pleasantness. The process of making consummatory choices relies on a network of brain regions to integrate and process chemosensory information. The mediodorsal thalamus is a higher-order thalamic nucleus involved in many experience-dependent chemosensory behaviors, including olfactory attention, odor discrimination, and the hedonic perception of flavors. Recent research has shown that neurons in the mediodorsal thalamus represent the sensory and affective properties of experienced odors, tastes, and odor-taste mixtures. However, its role in guiding consummatory choices remains unclear. To investigate the influence of the mediodorsal thalamus in the consummatory choice for experienced odors, tastes, and odor-taste mixtures, we pharmacologically inactivated the mediodorsal thalamus during 2-bottle brief-access tasks. We found that inactivation altered the preference for specific odor-taste mixtures, significantly reduced consumption of the preferred taste and increased within-trial sampling of both chemosensory stimulus options. Our results show that the mediodorsal thalamus plays a crucial role in consummatory decisions related to chemosensory preference and attention.

OBJECTIVE: Many older adults in the United States with serious persistent mental illness reside in long-term facilities, and evidence suggests increasing numbers of long-term care residents with serious persistent mental illness. Healthcare professionals in these settings may face challenges in providing care to these residents. The purpose of this study was to describe health care professionals' perceptions of the barriers and facilitators to caring for long-term care residents with serious persistent mental illness. METHODS: A qualitative descriptive design was employed. RESULTS: Ten healthcare professionals working in long-term care were interviewed. Themes that emerged from the interviews were: coming to know the individual and their unique needs takes time; offering choices and being flexible facilitates trust; respecting the inherent worth of each individual promotes caring. CONCLUSIONS: Caring for individuals with serious persistent mental illness in long-term care requires an individualized, person-centered approach.

Although CRISPR-Cas9 gene therapies have proven to be a powerful tool across many applications, improvements are necessary to increase the specificity of this technology. Cas9 cutting in off-target sites remains an issue that limits CRISPR's application in human-based therapies. Treatment of autosomal dominant diseases also remains a challenge when mutant alleles differ from the wild-type sequence by only one base pair. Here, we utilize synthetic peptide nucleic acids (PNAs) that bind selected spacer sequences in the guide RNA (gRNA) to increase Cas9 specificity up to 10-fold. We interrogate variations in PNA length, binding position, and degree of homology with the gRNA. Our findings reveal that PNAs bound in the region distal to the protospacer adjacent motif (PAM) site effectively enhance specificity in both on-target/off-target and allele-specific scenarios. In addition, we demonstrate that introducing deliberate mismatches between PNAs bound in the PAM-proximal region of the gRNA can modulate Cas9 activity in an allele-specific manner. These advancements hold promise for addressing current limitations and expanding the therapeutic potential of CRISPR technology.
RESUMEN
BACKGROUND: The enactment of the Health Information Technology for Economic and Clinical Health Act and the wide adoption of electronic health record (EHR) systems have ushered in increasing documentation burden, frequently cited as a key factor affecting the work experience of healthcare professionals and a contributor to burnout. This systematic review aims to identify and characterize measures of documentation burden. METHODS: We integrated discussions with Key Informants and a comprehensive search of the literature, including MEDLINE, Embase, Scopus, and gray literature published between 2010 and 2023. Data were narratively and thematically synthesized. RESULTS: We identified 135 articles about measuring documentation burden. We classified measures into 11 categories: overall time spent in EHR, activities related to clinical documentation, inbox management, time spent in clinical review, time spent in orders, work outside work/after hours, administrative tasks (billing and insurance related), fragmentation of workflow, measures of efficiency, EHR activity rate, and usability. The most common source of data for most measures was EHR usage logs. Direct tracking such as through time-motion analysis was fairly uncommon. Measures were developed and applied across various settings and populations, with physicians and nurses in the USA being the most frequently represented healthcare professionals. Evidence of validity of these measures was limited and incomplete. Data on the appropriateness of measures in terms of scalability, feasibility, or equity across various contexts were limited. The physician perspective was the most robustly captured and prominently focused on increased stress and burnout. DISCUSSION: Numerous measures for documentation burden are available and have been tested in a variety of settings and contexts. However, most are one-dimensional, do not capture various domains of this construct, and lack robust validity evidence. This report serves as a call to action highlighting an urgent need for measure development that represents diverse clinical contexts and support future interventions.
RESUMEN
Authorization of the Matrix-M (MM)-adjuvanted R21 vaccine by three countries and its subsequent endorsement by the World Health Organization for malaria prevention in children are a milestone in the fight against malaria. Yet, our understanding of the innate and adaptive immune responses elicited by this vaccine remains limited. Here, we compared three clinically relevant adjuvants [3M-052 + aluminum hydroxide (Alum) (3M), a TLR7/8 agonist formulated in Alum; GLA-LSQ, a TLR4 agonist formulated in liposomes with QS-21; and MM, the now-approved adjuvant for R21] for their capacity to induce durable immune responses to R21 in macaques. R21 adjuvanted with 3M on a 0, 8, and 23-week schedule elicited anti-circumsporozoite antibody responses comparable in magnitude to the R21/MM vaccine administered using a 0-4-8-week regimen and persisted up to 72 weeks with a half-life of 337 days. A booster dose at 72 weeks induced a recall response similar to the R21/MM vaccination. In contrast, R21/GLA-LSQ immunization induced a lower, short-lived response at the dose used. Consistent with the durable serum antibody responses, MM and 3M induced long-lived plasma cells in the bone marrow and other tissues, including the spleen. Furthermore, whereas 3M stimulated potent and persistent antiviral transcriptional and cytokine signatures after primary and booster immunizations, MM induced enhanced expression of interferon- and TH2-related signatures more highly after the booster vaccination. Collectively, these findings provide a resource on the immune responses of three clinically relevant adjuvants with R21 and highlight the promise of 3M as another adjuvant for malarial vaccines.

Women are disproportionately affected by symptoms of angina with nonobstructive coronary arteries (ANOCA) which is associated with significant mortality and economic impact. Although distinct endotypes of ANOCA have been defined, it is underdiagnosed and is often incompletely characterized when identified. Patients are often unresponsive to traditional therapeutic options, which are typically antianginal, and the current ability to guide treatment modification by specific pathways is limited. Studies have associated specific genetic loci, transcriptomic features, and biomarkers with ANOCA. Such panomic data, in combination with known imaging and invasive diagnostic techniques, should be utilized to define more precise pathophysiologic subtypes of ANOCA in women, which will in turn help to identify targeted, effective therapies. A precision medicine-based approach to managing ANOCA incorporating these techniques in women has the potential to significantly improve their clinical care.

RESUMEN
Adjuvant endocrine therapy (AET) reduces mortality in early-stage breast cancer, but adherence is low. We developed a multicomponent intervention to support AET adherence comprising: text messages, information leaflet, acceptance and commitment therapy (ACT), and side-effect website. Guided by the multiphase optimization strategy, the intervention components were tested in the ROSETA pilot optimization trial. Our mixed-methods process evaluation investigated component acceptability. The pilot optimization trial used a 24-1 fractional factorial design. Fifty-two women prescribed AET were randomized to one of eight experimental conditions, containing unique component combinations. An acceptability questionnaire was administered 4 months post-randomization, and semi-structured interviews with 20 participants further explored acceptability. Assessments were guided by four constructs of the theoretical framework of acceptability: affective attitude, burden, perceived effectiveness, and coherence. Quantitative and qualitative findings were triangulated to identify agreements/disagreements. There were high overall acceptability scores (median = 14-15/20, range = 11-20). There was agreement between the qualitative and quantitative findings when triangulated. Most participants "liked" or "strongly liked" all components and reported they required low effort to engage in. Between 50% (leaflet) and 65% (SMS) "agreed" or "strongly agreed," it was clear how each component would help adherence. Perceived effectiveness was mixed, with 35.0% (text messages) to 55.6% (ACT) of participants "agreeing" or "strongly agreeing" that each component would improve their adherence. Interview data provided suggestions for improvements. The four components were acceptable to women with breast cancer and will be refined. Mixed-methods and triangulation were useful methodological approaches and could be applied in other optimization trial process evaluations.
RESUMEN
Bariatric surgery (BS) is a leading treatment for obesity; however, adverse side effects (e.g., pain and infection) can deter patients or affect weight maintenance. This study investigates how a post-operative virtual health coaching lifestyle program, monitoring virtual weekly goal progress made by patients, affects weight loss after BS, specifically sleeve gastrectomy. Patients recruited for this 6-month study were classified with a BMI > 30 kg/m2 90 days post-operatively. Patients were prescribed lifestyle support delivered by certified health and wellness coaches (InHealth Lifestyle Therapeutics™). Demographic variables (e.g., age, weight, height, and gender) were obtained and compared according to initial, 3-, 6-month, and current weight through repeated measures ANOVA and post hoc comparison. Thirty-eight adult participants were included, with a mean age of 52 years ± 12.9 and with a majority (n = 35; 97%) of them being female. There were significant differences in weight reported across all five time points (p < 0.05), with the greatest weight difference seen between the initial (250.3 ± 45.5 lbs.) and final time points (226.7± 40.4 lbs.). This study suggests post-operative virtual health coaching can enhance weight loss outcomes after sleeve gastrectomy. Further research is needed to assess the long-term effects and cost-effectiveness of such a form of coaching for bariatric surgery patients.
