Social media as a platform for cancer care decision-making among women: Internet survey-based study on trust, engagement, and preferences

BACKGROUND: Decision aids improve patient and clinician decision-making but are underused and often restricted to clinical settings. OBJECTIVE: Given limited studies analyzing the feasibility of disseminating decision aids through social media, this study aimed to evaluate the acceptability, trust, and engagement of women with social media as a tool to deliver online decision aids for cancer treatment. METHODS: To prepare for potential dissemination of a breast cancer decision aid via social media, a cross-sectional survey in February 2023 was conducted via Prime Panels, an online market research platform, of women aged 35-75 years in the United States. Demographics, health, cancer information-seeking behaviors, social media use, trust in social media for health information, as well as the likelihood of viewing cancer-related health information and clicking on decision aids through social media, were assessed. Statistical analyses included descriptive statistics, correlations, and multivariable ordinal regression. RESULTS: Of 607 respondents, 397 (65.4%) had searched for cancer information, with 185 (46.6%) using the internet as their primary source. Facebook (Meta) was the most popular platform (511/607, 84.2%). Trust in social media for health information was higher among Black (14/72, 19.4%) and Asian respondents (7/27, 25.9%) than among White respondents (49/480, 10.2%; P=.003). Younger respondents aged 35-39 years (17/82, 20.7%) showed higher trust than those aged 70-79 years (12/70, 17.1%; P\u3c.001). Trust in social media for health information was linked to a higher likelihood of viewing cancer information and accessing a decision aid online (P\u3c.001). Participants who rated social media as Trustworthy (n=73) were more likely to view cancer information (61/73, 83.6%) and click on decision aids (61/73, 83.6%) than those who found it Untrustworthy (n=277; view: 133/277, 48.0%; click: 125/277, 45.1%). Engagement with social media positively correlated with viewing online cancer information (Spearman ρ=0.20, P\u3c.001) and willingness to use decision aids (ρ=0.21, P\u3c.001). Multivariable ordinal regression analyses confirmed that perception of social media\u27s trustworthiness is a significant predictor of engagement with decision aids (untrustworthy vs trustworthy β=-1.826, P\u3c.001; neutral vs trustworthy β=-0.926, P=.007) and of viewing cancer information (untrustworthy vs trustworthy β=-1.680, P\u3c.001, neutral vs trustworthy β=-0.581, P=.098), while age and employment status were not significant predictors. CONCLUSIONS: This exploratory study suggests that social media platforms may increase access to health information and decision aids. No significant differences were observed between demographic variables and the use or trust in social media for health information. However, trust in social media emerged as a mediating factor between demographics and engagement with cancer information online. Before disseminating decision aids on social media, groups should identify existing trust and engagement patterns with different platforms within their target demographic

Measuring and interpreting individual differences in fetal, infant, and toddler neurodevelopment

As scientists interested in fetal, infant, and toddler (FIT) neurodevelopment, our research questions often focus on how individual children differ in their neurodevelopment and the predictive value of those individual differences for long-term neural and behavioral outcomes. Measuring and interpreting individual differences in neurodevelopment can present challenges: Is there a standard way for the human brain to develop? How do the semantic, practical, or theoretical constraints that we place on studying development influence how we measure and interpret individual differences? While it is important to consider these questions across the lifespan, they are particularly relevant for conducting and interpreting research on individual differences in fetal, infant, and toddler neurodevelopment due to the rapid, profound, and heterogeneous changes happening during this period, which may be predictive of long-term outcomes. This article, therefore, has three goals: 1) to provide an overview about how individual differences in neurodevelopment are studied in the field of developmental cognitive neuroscience, 2) to identify challenges and considerations when studying individual differences in neurodevelopment, and 3) to discuss potential implications and solutions moving forward

Patients\u27 attitudes to magnetic resonance imaging in perianal fistulizing Crohn\u27s disease: A global survey

BACKGROUND: There is limited patient involvement in radiological research for perianal fistulizing Crohn\u27s disease (pfCD), despite magnetic resonance imaging (MRI)\u27s critical role in diagnosis and management. Patient and public involvement is essential for aligning research with patient priorities. This study aimed to gather patient perspectives on the use of MRI in pfCD. METHODS: A mixed-methods approach was used, following Guidance for Reporting Involvement of Patients and the Public (GRIPP2) guidelines. An online survey, co-developed with a patient representative, included open and closed questions on MRI experiences, advantages, challenges, and the potential for Artificial Intelligence (AI)-generated reports. This was followed by a virtual session for further exploration of patient views. Thematic analysis was conducted on the data. RESULTS: Forty-seven patients with Crohn\u27s disease (37 with pfCD) from 6 countries participated, with 28/37 (76%) completing the survey. Key themes included patient expectations for MRI, preferences for scan intervals, and report content. Most (93%) wanted MRI reports to compare with previous scans, highlighting fistula changes and new abscesses. A majority (57%) preferred MRI scans annually when well, and more frequently after surgery (64.3% preferred scans at 3 months). Emotional relief was associated with MRI improvements, though access to services and report clarity remained challenging. Interest in AI-generated reports was expressed if clearly explained and validated by professionals. CONCLUSIONS: This is the first study exploring patient views on MRI use in pfCD, emphasizing the need for patient-centred MRI reporting and clearer communication. Future work should enhance patient access and validate AI-generated MRI reports

Racial equity in urine drug screening policies in labor and delivery

IMPORTANCE: Black pregnant patients are significantly more likely than their White counterparts to undergo peripartum urine drug screening (UDS) and subsequent reporting to child protective services (CPS). OBJECTIVE: To evaluate the association of removing isolated cannabis use and limited prenatal care as order indications, combined with clinician-facing clinical decision support, with racial parity in peripartum UDS and CPS reporting. DESIGN, SETTING, AND PARTICIPANTS: This quality improvement study assessed 9396 pregnant patients at a single tertiary care center in a Midwestern US urban metropolitan region who delivered before (June 1, 2021, to September 31, 2022) and after (October 1, 2022, to January 31, 2024) the intervention. EXPOSURE: Updated UDS indications combined with clinical decision support. MAIN OUTCOMES AND MEASURES: Primary outcomes included UDS and CPS report rate by race before vs after the intervention. The secondary outcome was the rate of nonprescribed, noncannabis substance-positive UDS. Neonatal outcomes were included as balancing measures. RESULTS: Of 9396 female patients (median [IQR] age, 29 [24-33] years; 4305 [45.8%] Black, 4277 [45.5%] White, and 814 [8.7%] other race) included in the analysis, 4639 and 4757 delivered in the preintervention and postintervention periods, respectively. There was a small but statistically significant decrease in the number of Black patients before vs after the intervention (2210 [47.6%] vs 2095 [44.0%], P = .005); there were no significant differences in other race groups, median age, or multiparity. Before the intervention, 513 (23.2%) and 228 (11.1%) Black and White patients, respectively, had UDS (P \u3c .001) compared with 95 (4.5%) and 79 (3.6%) Black and White patients, respectively, after the intervention (P = .40). Before the intervention, an association between Black race and CPS report was observed (249 [11.3%] Black and 119 [5.8%] White patients, P \u3c .001); there was no association between race and CPS report after the intervention (87 [4.2%] Black and 78 [3.5%] White patients, P = .67). There was no association between the intervention and the percentage of UDS results that were positive for nonprescribed, noncannabis substances (107 [2.5%] preintervention vs 88 [2.0%] postintervention; P = .14). There was no significant association between the intervention and any measured neonatal outcomes. CONCLUSIONS AND RELEVANCE: In this quality improvement study, removal of isolated cannabis use and limited prenatal care as UDS indications, coupled with clinical decision support, was associated with improved racial equity in UDS testing and CPS reporting. The intervention was not associated with a significant change in UDS positivity for nonprescribed, noncannabis substances. These findings suggest that this intervention improved equity in UDS practices without decreasing identification of clinically relevant substance use

Virologic effects of broadly neutralizing antibodies VRC01LS and VRC07-523LS on chronic HIV-1 infection

BACKGROUNDHIV-1-specific broadly neutralizing monoclonal antibodies (bNAbs) have emerged as promising interventions with the potential to effectively treat and prevent HIV-1 infections. We conducted a phase I clinical trial evaluating the potent CD4-binding site-specific (CD4bs-specific) bNAbs VRC01LS and VRC07-523LS in people with HIV-1 (PWH) not receiving antiretroviral therapy (ART).METHODSParticipants received a single intravenous 40 mg/kg dose of either VRC01LS (n = 7) or VRC07-523LS (n = 9) and did not initiate ART for a minimum of 14 days. The primary study objective was to evaluate safety and tolerability; the secondary study objectives were to evaluate pharmacokinetics (PK) and the impact of administered bNAbs on viral loads (VL) and CD4+ T cell counts in the absence of ART.RESULTSThis trial enrolled 16 PWH aged 20 to 57 years. Both bNAbs were safe and well tolerated. Mild local reactogenicity was only reported in participants who received VRC07-523LS, while both bNAbs were associated with mild systemic symptoms. Maximum serum concentrations (Cmax) following VRC01LS or VRC07-523LS were 1,566 ± 316 and 1,295 ± 376 μg/mL, respectively. VRC07-523LS administration significantly decreased VL in 8 out of 9 participants, with an average decline of 1.7 ± 0.8 log10 copies/mL within 14 days after administration. In contrast, VRC01LS administration resulted in a smaller average decline (0.8 ± 0.8 log10 copies/mL), and 3 out of 7 participants showedno change in VL. Postinfusion maximum decline in VL correlated with post hoc baseline in vitro viral susceptibility results for both bNAbs.CONCLUSIONThe results of this trial support inclusion of potent CD4bs-specific bNAbs, such as VRC07-523LS, into next-generation treatment regimens for HIV-1.TRIAL REGISTRATIONClinicalTrials.gov NCT02840474.FUNDINGNational Institute of Allergy and Infectious Diseases (NIAID)/NIH (grants UM1 AI068634, UM1 AI068636, UM1 AI106701, UM1AI069424, UM1AI069501, UM1AI69415, UM1AI069534, UM1AI69494); the Intramural Research Program of the NIAID/NIH; National Center for Advancing Translational Sciences/NIH (grants UM1TR004548, UL1TR001881, and UL1TR001878); and the National Cancer Institute/NIH (contract 75N91019D00024)

Phosphorylation of CRYAB induces a condensatopathy to worsen post-myocardial infarction left ventricular remodeling

Protein aggregates are emerging therapeutic targets in rare monogenic causes of cardiomyopathy and amyloid heart disease, but their role in more prevalent heart-failure syndromes remains mechanistically unexamined. We observed mislocalization of desmin and sarcomeric proteins to aggregates in human myocardium with ischemic cardiomyopathy and in mouse hearts with post-myocardial infarction ventricular remodeling, mimicking findings of autosomal-dominant cardiomyopathy induced by the R120G mutation in the cognate chaperone protein CRYAB. In both syndromes, we demonstrate increased partitioning of CRYAB phosphorylated on serine 59 to NP40-insoluble aggregate-rich biochemical fraction. While CRYAB undergoes phase separation to form condensates, the phosphomimetic mutation of serine 59 to aspartate (S59D) in CRYAB mimics R120G-CRYAB mutants with reduced condensate fluidity, formation of protein aggregates, and increased cell death. Conversely, changing serine to alanine (phosphorylation-deficient mutation) at position 59 (S59A) restored condensate fluidity and reduced both R120G-CRYAB aggregates and cell death. In mice, S59D CRYAB knockin was sufficient to induce desmin mislocalization and myocardial protein aggregates, while S59A CRYAB knockin rescued left ventricular systolic dysfunction after myocardial infarction and preserved desmin localization with reduced myocardial protein aggregates. 25-Hydroxycholesterol attenuated CRYAB serine 59 phosphorylation and rescued post-myocardial infarction adverse remodeling. Thus, targeting CRYAB phosphorylation-induced condensatopathy is an attractive strategy to counter ischemic cardiomyopathy

RAG suppresses group 2 innate lymphoid cells

Antigen specificity is the central trait distinguishing adaptive from innate immune function. Assembly of antigen-specific T cell and B cell receptors occurs through V(D)J recombination mediated by the Recombinase Activating Gene endonucleases RAG1 and RAG2 (collectively called RAG). In the absence of RAG, mature T and B cells do not develop and thus RAG is critically associated with adaptive immune function. In addition to adaptive T helper 2 (Th2) cells, group 2 innate lymphoid cells (ILC2s) contribute to type 2 immune responses by producing cytokines like Interleukin-5 (IL-5) and IL-13. Although it has been reported that RAG expression modulates the function of innate natural killer (NK) cells, whether other innate immune cells such as ILC2s are affected by RAG remains unclear. We find that in RAG-deficient mice, ILC2 populations expand and produce increased IL-5 and IL-13 at steady state and contribute to increased inflammation in atopic dermatitis (AD)-like disease. Furthermore, we show that RAG modulates ILC2 function in a cell-intrinsic manner independent of the absence or presence of adaptive T and B lymphocytes. Lastly, employing multiomic single cell analyses of RAG1 lineage-traced cells, we identify key transcriptional and epigenomic ILC2 functional programs that are suppressed by a history of RAG expression. Collectively, our data reveal a novel role for RAG in modulating innate type 2 immunity through suppression of ILC2s

Neutralizing antibody immune correlates in COVAIL trial recipients of an mRNA second COVID-19 vaccine boost

Neutralizing antibody titer has been a surrogate endpoint for guiding COVID-19 vaccine approval and use, although the pandemic\u27s evolution and the introduction of variant-adapted vaccine boosters raise questions as to this surrogate\u27s contemporary performance. For 985 recipients of an mRNA second bivalent or monovalent booster containing various Spike inserts [Prototype (Ancestral), Beta, Delta, and/or Omicron BA.1 or BA.4/5] in the COVAIL trial (NCT05289037), titers against 5 strains were assessed as correlates of risk of symptomatic COVID-19 ( COVID-19 ) and as correlates of relative (Pfizer-BioNTech Omicron vs. Prototype) booster protection against COVID-19 over 6 months of follow-up during the BA.2-BA.5 Omicron-dominant period. Consistently across the Moderna and Pfizer-BioNTech vaccine platforms and across all variant Spike inserts assessed, both peak and exposure-proximal ( predicted-at-exposure ) titers correlated with lower Omicron COVID-19 risk in individuals previously infected with SARS-CoV-2, albeit significantly less so in naïve individuals [e.g., exposure-proximal hazard ratio per 10-fold increase in BA.1 titer 0.74 (95% CI 0.59, 0.94) for naïve vs. 0.41 (95% CI 0.23, 0.64) for non-naïve; interaction p = 0.013]. Neutralizing antibody titer was a strong inverse correlate of Omicron COVID-19 in non-naïve individuals and a weaker correlate in naïve individuals, posing questions about how prior infection alters the neutralization correlate

Clinical impact of endoscopy in severely thrombocytopenic patients with hematologic malignancy experiencing gastrointestinal bleeding

BACKGROUND: Gastrointestinal bleeding (GIB) is a major cause of hospitalization worldwide. Patients with hematologic malignancies have a higher risk of GIB as a result of thrombocytopenia and platelet dysfunction. There is no consensus on the optimal platelet level that would be safe for endoscopic intervention, although a platelet level of \u3e 50 × 10 AIM: To assess the safety of endoscopic intervention of inpatients with hematological malignancies and severe thrombocytopenia presenting with acute overt GIB. METHODS: This is a single center retrospective study. The data was collected from the electronic health record from 2018 to 2020. Inpatients with hematologic malignancy who presented with acute overt GIB and platelet count ≤ 50 × 10 RESULTS: A total of 76 patients were identified. The mean platelet count is 24.3 in the endoscopy arm and 14.6 in the conservative management arm. There was no statistically significant difference between patients who had endoscopy CONCLUSION: Medical supportive treatment without endoscopy could be considered as an alternative to endoscopic therapy for patients with hematologic malignancy complicated by severe thrombocytopenia and acute non-variceal GIB

SLC35A2 gene product modulates paramyxovirus fusion events during infection

Paramyxoviruses are significant human and animal pathogens that include mumps virus (MuV), Newcastle disease virus (NDV) and the murine parainfluenza virus Sendai (SeV). Despite their importance, few host factors implicated in paramyxovirus infection are known. Using a recombinant SeV expressing destabilized eGFP (rSeVCdseGFP) in a loss-of-function CRISPR screen, we identified the CMP-sialic acid transporter (CST) gene SLC35A1 and the UDP-galactose transporter (UGT) gene SLC35A2 as essential for paramyxovirus infection. As expected, SLC35A1 knockout (KO) cells showed drastic reduction in infections with SeV, NDV and MuV due to the lack of cell surface sialic acids receptors. However, SLC35A2 KO cells revealed unknown critical roles for this factor in virus-cell and cell-to-cell fusion events for the different paramyxoviruses. While UGT was essential for virus-cell fusion during SeV entry to the cell, it was not required for NDV or MuV entry. Importantly, UGT promoted the formation of syncytia during MuV infection, suggesting a role in cell-to-cell virus spread. Our findings demonstrate that paramyxoviruses can bind to or enter A549 cells in the absence of canonical galactose-bound sialic-acid decorations and show that UGT facilitates paramyxovirus fusion processes involved in entry and spread
