Trends in Continuation of Long-Acting Reversible Contraception Among Adolescents Receiving Medicaid.

PURPOSE: Despite increasing use of long-acting reversible contraception (LARC) among U.S. adolescents, there is limited literature on factors affecting intrauterine device (IUD) or subdermal implant use. This study aimed to describe statewide rates, and associated patient and provider factors of adolescent IUD or implant initiation and continuation. METHODS: This retrospective cohort study used N.C. Medicaid claims data. 10,408 adolescents were eligible (i.e., 13-19 years, female sex, continuous Medicaid enrollment, had an IUD or implant insertion or removal code from January 1, 2013, to October 1, 2015). Bivariate analyses assessed differences in adolescents using IUD versus implant. Kaplan-Meier curves were created to assess IUD or implant discontinuation through December 31, 2018. RESULTS: Adolescents initiated 8,592 implants and 3,369 IUDs (N = 11,961). There were significant differences in nearly all provider and patient factors for those who initiated implants versus IUDs. 16% of implants and 53% of IUDs were removed in the first year. Younger (i.e., age <18 years old), Hispanic, and Black adolescents had higher adjusted continuation of implants compared with older and White adolescents, respectively (both p < .001). Those whose IUD was inserted by an obstetrician/gynecologist provider had lower continuation of IUDs compared with non-obstetrician/gynecologist providers (p < .001). DISCUSSION: We found that age-related, racial, and ethnic disparities exist in both implant and IUD continuation. Practice changes to support positive adolescent experiences with implant and IUD insertion and removals are needed, including patient-centered health care provider training in contraception counseling, LARC initiation and removal training for adolescent-facing providers, and broader clinic capacity for LARC services.

The perceived impact of a post-Dobbs landscape on U.S. adolescents and young adults.

OBJECTIVE(S): To capture the perspectives and knowledge of adolescents and young adults on abortion-related topics following the Dobbs decision. STUDY DESIGN: Qualitative content analysis of an open-ended, five-question survey fielded on October 28, 2022 via the MyVoice project, a nationwide weekly text message poll of 14-24-year-olds. RESULTS: We found the respondents (N = 565, response rate 71%) had a mean age of 20.0 years and resided in 47 states. Many described pro- or anti-abortion changes to abortion access in their state, though expressed mixed emotions about the changes (negative, positive, or mixed/neutral). Most often, they had conversations about abortion with peers (28%), followed by parents or family (20%); nearly 20% stated they have never had a conversation about abortion. The majority of respondents (55%) believed they and their peers should have access to abortion care without required parental consent/notification, frequently citing individual rights/autonomy (31%) followed by harms of parental involvement (12%). Most (79%) provided a technique for how to determine if online information about abortion was trustworthy. CONCLUSION(S): Four months after the Dobbs decision, this national sample of adolescents and young adults were aware of changes to abortion access, had conversations about abortion, shared diverse opinions on parental consent or notification laws, and could determine trustworthiness of online abortion resources. Abortion-related policy and practice can be improved by understanding adolescents' and young adults' needs and preferences, trusting and supporting their autonomy, and reducing barriers to care. IMPLICATIONS: This study highlights the timely perspectives and experiences of a diverse, nationwide sample of adolescents and young adults on abortion-related topics. Findings can support centering adolescents and young adults in practice and policy changes to improve their knowledge about abortion and streamline access to essential reproductive health services post-Dobbs.

Technical recommendations for implementation of Volumetric Modulated Arc Therapy and Helical Tomotherapy Total Body Irradiation.

As a component of myeloablative conditioning before allogeneic hematopoietic stem cell transplantation (HSCT), Total Body Irradiation (TBI) is employed in radiotherapy centers all over the world. In recent and coming years, many centers are changing their technical setup from a conventional TBI technique to multi-isocenter conformal arc therapy techniques such as Volumetric Modulated Arc Therapy (VMAT) or Helical Tomotherapy (HT). These techniques allow better homogeneity and control of the target prescription dose, and provide more freedom for individualized organ-at-risk sparing. The technical design of multi-isocenter/multi-plan conformal TBI is complex and should be developed carefully. A group of early adopters with conformal TBI experience using different treatment machines and treatment planning systems came together to develop technical recommendations and share experiences, in order to assist departments wishing to implement conformal TBI, and to provide ideas for standardization of practices.

Disruption of dopamine D2/D3 system function impairs the human ability to understand the mental states of other people.

Difficulties in reasoning about others' mental states (i.e., mentalising/Theory of Mind) are highly prevalent among disorders featuring dopamine dysfunctions (e.g., Parkinson's disease) and significantly affect individuals' quality of life. However, due to multiple confounding factors inherent to existing patient studies, currently little is known about whether these sociocognitive symptoms originate from aberrant dopamine signalling or from psychosocial changes unrelated to dopamine. The present study, therefore, investigated the role of dopamine in modulating mentalising in a sample of healthy volunteers. We used a double-blind, placebo-controlled procedure to test the effect of the D2/D3 antagonist haloperidol on mental state attribution, using an adaptation of the Heider and Simmel (1944) animations task. On 2 separate days, once after receiving 2.5 mg haloperidol and once after receiving placebo, 33 healthy adult participants viewed and labelled short videos of 2 triangles depicting mental state (involving mentalistic interaction wherein 1 triangle intends to cause or act upon a particular mental state in the other, e.g., surprising) and non-mental state (involving reciprocal interaction without the intention to cause/act upon the other triangle's mental state, e.g., following) interactions. Using Bayesian mixed effects models, we observed that haloperidol decreased accuracy in labelling both mental and non-mental state animations. Our secondary analyses suggest that dopamine modulates inference from mental and non-mental state animations via independent mechanisms, pointing towards 2 putative pathways underlying the dopaminergic modulation of mental state attribution: action representation and a shared mechanism supporting mentalising and emotion recognition. We conclude that dopaminergic pathways impact Theory of Mind, at least indirectly. Our results have implications for the neurochemical basis of sociocognitive difficulties in patients with dopamine dysfunctions and generate new hypotheses about the specific dopamine-mediated mechanisms underlying social cognition.

Fluid Biomarkers in Individuals at Risk for Genetic Prion Disease up to Disease Conversion.

OBJECTIVES: To longitudinally characterize disease-relevant CSF and plasma biomarkers in individuals at risk for genetic prion disease up to disease conversion. METHODS: This single-center longitudinal cohort study has followed known carriers of PRNP pathogenic variants at risk for prion disease, individuals with a close relative who died of genetic prion disease but who have not undergone predictive genetic testing, and controls. All participants were asymptomatic at first visit and returned roughly annually. We determined PRNP genotypes, measured NfL and GFAP in plasma, and RT-QuIC, total PrP, NfL, T-tau, and beta-synuclein in CSF. RESULTS: Among 41 carriers and 21 controls enrolled, 28 (68%) and 15 (71%) were female, and mean ages were 47.5 and 46.1. At baseline, all individuals were asymptomatic. We observed RT-QuIC seeding activity in the CSF of 3 asymptomatic E200K carriers who subsequently converted to symptomatic and died of prion disease. 1 P102L carrier remained RT-QuIC negative through symptom conversion. No other individuals developed symptoms. The prodromal window from detection of RT-QuIC positivity to disease onset was 1 year long in an E200K individual homozygous (V/V) at PRNP codon 129 and 2.5 and 3.1 years in 2 codon 129 heterozygotes (M/V). Changes in neurodegenerative and neuroinflammatory markers were variably observed prior to onset, with increases observed for plasma NfL in 4/4 converters, and plasma GFAP, CSF NfL, CSF T-tau, and CSF beta-synuclein each in 2/4 converters, although values relative to age and fold changes relative to individual baseline were not remarkable for any of these markers. CSF PrP was longitudinally stable with mean coefficient of variation 9.0% across all individuals over up to 6 years, including data from converting individuals at RT-QuIC-positive timepoints. DISCUSSION: CSF prion seeding activity may represent the earliest detectable prodromal sign in E200K carriers. Neuronal damage and neuroinflammation markers show limited sensitivity in the prodromal phase. CSF PrP levels remain stable even in the presence of RT-QuIC seeding activity.

Increasing access to LARC removal in pediatrics to support adolescent reproductive justice in the United States.

BACKGROUND: In the United States (U.S.), adolescents and young adults are increasingly using contraception, including long-acting reversible contraception (LARC) [e.g., subdermal implants (e.g., Nexplanon®) and intrauterine devices (IUDs)]; however, access to LARC device removal may be difficult for adolescents and young adults. Reproductive justice is the right to bodily autonomy, have children, not have children, and safely parent the children we have. METHODS: In this commentary, we discuss that while the specialties of family medicine and obstetrics and gynecology have incorporated the principles of reproductive justice into their contraceptive care, further work is needed to ingrain this philosophy into pediatrics training. Since LARC devices are historically only removable by health care providers, pediatricians may act as gatekeepers to removing LARC, obstructing the reproductive justice of adolescents and young adults. RESULTS: We describe that adolescents and young adults in the U.S. face unique barriers to LARC removal including limited access to the health care system, potential breaches in confidentiality, and provider bias. These barriers may lead adolescents and young adults to remove their own LARC device when experiencing unwanted side effects or desiring pregnancy. While IUD self-removal is a safe and accessible option, safety and efficacy data on subdermal implant self-removal is currently limited. CONCLUSION: In order to promote reproductive justice in adolescents and young adults, we recommend that (1) pediatricians should address potential barriers to LARC removal prior to insertion, (2) pediatricians must offer unbiased LARC removal, (3) pediatricians who place LARC must be knowledgeable about complicated LARC removal, and (4) pediatricians should discuss LARC self-removal options with adolescents and young adults.

Mapping Conformational Changes in the Saliva Proteome Potentially Associated with Oral Cancer Aggressiveness.

Diverse proteomics-based strategies have been applied to saliva to quantitatively identify diagnostic and prognostic targets for oral cancer. Considering that these targets may be regulated by events that do not imply variation in protein abundance levels, we hypothesized that changes in protein conformation can be associated with diagnosis and prognosis, revealing biological processes and novel targets of clinical relevance. For this, we employed limited proteolysis-mass spectrometry in saliva samples to explore structural alterations, comparing the proteome of healthy control and oral squamous cell carcinoma (OSCC) patients with and without lymph node metastasis. Thirty-six proteins with potential structural rearrangements were associated with clinical patient features including transketolase and its interacting partners. Moreover, N-glycosylated peptides contribute to structural rearrangements of potential diagnostic and prognostic markers. Altogether, this approach utilizes saliva proteins to search for targets for diagnosing and prognosing oral cancer and can guide the discovery of potential regulated sites beyond protein-level abundance.

Amphotericin B resistance in Leishmania amazonensis: In vitro and in vivo characterization of a Brazilian clinical isolate.

In Brazil, Leishmania amazonensis is the etiological agent of cutaneous and diffuse cutaneous leishmaniasis. The state of Maranhão in the Northeast of Brazil is prevalent for these clinical forms of the disease and also has high rates of HIV infection. Here, we characterized the drug susceptibility of a L. amazonensis clinical isolate from a 46-year-old man with diffuse cutaneous leishmaniasis coinfected with HIV from this endemic area. This patient underwent several therapeutic regimens with meglumine antimoniate, liposomal amphotericin B, and pentamidine, without success. In vitro susceptibility assays against promastigotes and intracellular amastigotes demonstrated that this isolate had low susceptibility to amphotericin B, when compared with the reference strain of this species that is considered susceptible to antileishmanial drugs. Additionally, we investigated whether the low in vitro susceptibility would affect the in vivo response to amphotericin B treatment. The drug was effective in reducing the lesion size and parasite burden in mice infected with the reference strain, whereas those infected with the clinical isolate and a resistant line (generated experimentally by stepwise selection) were refractory to amphotericin B treatment. To evaluate whether the isolate was intrinsically resistant to amphotericin B in animals, infected mice were treated with other drugs that had not been used in the treatment of the patient (miltefosine, paromomycin, and a combination of both). Our findings demonstrated that all drug schemes were able to reduce lesion size and parasite burden in animals infected with the clinical isolate, confirming the amphotericin B-resistance phenotype. These findings indicate that the treatment failure observed in the patient may be associated with amphotericin B resistance, and demonstrate the potential emergence of amphotericin B-resistant L. amazonensis isolates in an area of Brazil endemic for cutaneous leishmaniasis.

Immune mechanisms in the pathophysiology of hypertension.

Hypertension is a leading risk factor for morbidity and mortality worldwide. Despite current anti-hypertensive therapies, most individuals with hypertension fail to achieve adequate blood pressure control. Moreover, even with adequate control, a residual risk of cardiovascular events and associated organ damage remains. These findings suggest that current treatment modalities are not addressing a key element of the underlying pathology. Emerging evidence implicates immune cells as key mediators in the development and progression of hypertension. In this Review, we discuss our current understanding of the diverse roles of innate and adaptive immune cells in hypertension, highlighting key findings from human and rodent studies. We explore mechanisms by which these immune cells promote hypertensive pathophysiology, shedding light on their multifaceted involvement. In addition, we highlight advances in our understanding of autoimmunity, HIV and immune checkpoints that provide valuable insight into mechanisms of chronic and dysregulated inflammation in hypertension.

A systematic review of the efficacy of group social skills interventions on social functioning and social participation in children with acquired brain injury or cerebral palsy.

AIM: The aim of this study was to evaluate the efficacy of Group social skills interventions (GSSIs) versus any comparator on social functioning in children aged 5-12 years with acquired brain injury or cerebral palsy. BACKGROUND: GSSIs are an evidence-based approach to foster social skills development in children with autism spectrum disorder. Currently, limited literature exploring GSSIs in children with acquired brain injury and cerebral palsy is available. RESULTS: MEDLINE, SCOPUS, Embase, CINAHL, Cochrane Library, PsycINFO, clinicaltrials.gov, ICTRP and ProQuest Dissertations and Theses were systematically searched. Study screening, risk-of-bias, Grading of Recommendations Assessment, Development and Evaluation and data extraction were performed in duplicate. Six studies were included in the narrative synthesis (one randomised controlled trial and five nonrandomised studies). Results indicate that GSSIs may increase children's social skills as measured on the Social Skills Rating System and Social Skills Questionnaire. Very low certainty evidence was found for improvements in social functioning and competence. CONCLUSIONS: There is low certainty evidence that participation in GSSI may lead to gains in social functioning for children with acquired brain injury or cerebral palsy. Given the certainty of the evidence, these results must be interpreted with caution. Only one randomised controlled trial of GSSIs for children with acquired brain injury was identified, underscoring the need for additional high-quality studies.

TRIM33 Is a Co-Regulator of Estrogen Receptor Alpha.

Estrogen receptor alpha (ER)-positive breast cancer is responsible for over 60% of breast cancer cases in the U.S. Among patients diagnosed with early-stage ER+ disease, 1/3 will experience recurrence despite treatment with adjuvant endocrine therapy. ER is a nuclear hormone receptor responsible for estrogen-driven tumor growth. ER transcriptional activity is modulated by interactions with coregulators. Dysregulation of the levels of these coregulators is involved in the development of endocrine resistance. To identify ER interactors that modulate transcriptional activity in breast cancer, we utilized biotin ligase proximity profiling of ER interactomes. Mass spectrometry analysis revealed tripartite motif containing 33 (TRIM33) as an estrogen-dependent interactor of ER. shRNA knockdown showed that TRIM33 promoted ER transcriptional activity and estrogen-induced cell growth. Despite its known role as an E3 ubiquitin ligase, TRIM33 increased the stability of endogenous ER in breast cancer cells. TRIM33 offers a novel target for inhibiting estrogen-induced cancer cell growth, particularly in cases of endocrine resistance driven by ER (ESR1) gene amplification or overexpression.

Unveiling the Antiviral Capabilities of Targeting Human Dihydroorotate Dehydrogenase against SARS-CoV-2.

The urgent need for effective treatments against emerging viral diseases, driven by drug-resistant strains and new viral variants, remains critical. We focus on inhibiting the human dihydroorotate dehydrogenase (HsDHODH), one of the main enzymes responsible for pyrimidine nucleotide synthesis. This strategy could impede viral replication without provoking resistance. We evaluated naphthoquinone fragments, discovering potent HsDHODH inhibition with IC50 ranging from 48 to 684 nM, and promising in vitro anti-SARS-CoV-2 activity with EC50 ranging from 1.2 to 2.3 µM. These compounds exhibited low toxicity, indicating potential for further development. Additionally, we employed computational tools such as molecular docking and quantitative structure-activity relationship (QSAR) models to analyze protein-ligand interactions, revealing that these naphthoquinones exhibit a protein binding pattern similar to brequinar, a potent HsDHODH inhibitor. These findings represent a significant step forward in the search for effective antiviral treatments and have great potential to impact the development of new broad-spectrum antiviral drugs.

Plasma VEGFA and PGF impact longitudinal tau and cognition in preclinical Alzheimer's disease.

Vascular dysfunction is increasingly recognized as an important contributor to the pathogenesis of Alzheimer's disease. Alterations in vascular endothelial growth factor (VEGF) pathways have been implicated as potential mechanisms. However, the specific impact of VEGF proteins in preclinical Alzheimer's disease and their relationships with other Alzheimer's disease and vascular pathologies during this critical early period remain to be elucidated. We included 317 older adults from the Harvard Aging Brain Study, a cohort of individuals who were cognitively unimpaired at baseline and followed longitudinally for up to 12 years. Baseline VEGF family protein levels (VEGFA, VEGFC, VEGFD, PGF and FLT1) were measured in fasting plasma using high-sensitivity immunoassays. Using linear mixed effects models, we examined the interactive effects of baseline plasma VEGF proteins and amyloid PET burden (Pittsburgh Compound-B) on longitudinal cognition (Preclinical Alzheimer Cognitive Composite-5). We further investigated if effects on cognition were mediated by early neocortical tau accumulation (flortaucipir PET burden in the inferior temporal cortex) or hippocampal atrophy. Lastly, we examined the impact of adjusting for baseline cardiovascular risk score or white matter hyperintensity volume. Baseline plasma VEGFA and PGF each showed a significant interaction with amyloid burden on prospective cognitive decline. Specifically, low VEGFA and high PGF were associated with greater cognitive decline in individuals with elevated amyloid, i.e. those on the Alzheimer's disease continuum. Concordantly, low VEGFA and high PGF were associated with accelerated longitudinal tau accumulation in those with elevated amyloid. Moderated mediation analyses confirmed that accelerated tau accumulation fully mediated the effects of low VEGFA and partially mediated (31%) the effects of high PGF on faster amyloid-related cognitive decline. The effects of VEGFA and PGF on tau and cognition remained significant after adjusting for cardiovascular risk score or white matter hyperintensity volume. There were concordant but non-significant associations with longitudinal hippocampal atrophy. Together, our findings implicate low VEGFA and high PGF in accelerating early neocortical tau pathology and cognitive decline in preclinical Alzheimer's disease. Additionally, our results underscore the potential of these minimally-invasive plasma biomarkers to inform the risk of Alzheimer's disease progression in the preclinical population. Importantly, VEGFA and PGF appear to capture distinct effects from vascular risks and cerebrovascular injury. This highlights their potential as new therapeutic targets, in combination with anti-amyloid and traditional vascular risk reduction therapies, to slow the trajectory of preclinical Alzheimer's disease and delay or prevent the onset of cognitive decline.

"It Means Being Safe, Having Power over One's Body": Black Female Adolescent Experiences with Reproductive Health Counseling in Primary Care.

STUDY OBJECTIVE: There is limited research examining the sexual and reproductive health (SRH) care needs and experiences of Black adolescents who are assigned female at birth (AFAB). This study aimed to understand the perspectives of Black AFAB adolescents in their receipt of SRH counseling in primary care and elicit preferences for SRH-related communication with clinicians. METHODS: We interviewed English-speaking Black AFAB adolescents, ages 13-17, living in North Carolina between February and June 2022 about their SRH care experiences. The interviews were conducted via video conferencing, audio-recorded, professionally transcribed, and analyzed using a thematic approach. RESULTS: We interviewed 23 adolescents (mean age 15.8 years) across 10 geographically diverse counties in North Carolina. Most conveyed positive perceptions of clinicians regarding trust and comfort. However, many expressed concerns about clinicians not doing enough to ensure patient confidentiality, provide them with enough information to make informed and autonomous decisions, and destigmatize discussing SRH issues during the clinical encounter. Suggested improvements include sociodemographic congruence between patients and clinicians (eg, younger Black women), ensuring time alone with clinicians across adolescence, and proactively sharing information to promote respect and autonomy. CONCLUSION: Although Black AFAB adolescents had positive perceptions of their health care providers regarding relational components of care, many participants shared significant gaps and areas for improvement in the quality of care received to better align services with their preferences for SRH care. These findings can inform the development of SRH counseling best practices and clinician education to support respect and autonomy, which are routinely denied to Black AFAB adolescents.

Cerebrospinal fluid biomarker profiling of diverse pathophysiological domains in Alzheimer's disease.

INTRODUCTION: While Alzheimer's disease (AD) is defined by amyloid-ß plaques and tau tangles in the brain, it is evident that many other pathophysiological processes such as inflammation, neurovascular dysfunction, oxidative stress, and metabolic derangements also contribute to the disease process and that varying contributions of these pathways may reflect the heterogeneity of AD. Here, we used a previously validated panel of cerebrospinal fluid (CSF) biomarkers to explore the degree to which different pathophysiological domains are dysregulated in AD and how they relate to each other. METHODS: Twenty-five CSF biomarkers were analyzed in individuals with a clinical diagnosis of AD verified by positive CSF AD biomarkers (AD, n = 54) and cognitively unimpaired controls negative for CSF AD biomarkers (CU-N, n = 26) using commercial single- and multi-plex immunoassays. RESULTS: We noted that while AD was associated with increased levels of only three biomarkers (MMP-10, FABP3, and 8OHdG) on a group level, half of all AD participants had increased levels of biomarkers belonging to at least two pathophysiological domains reflecting the diversity in AD. LASSO modeling showed that a panel of FABP3, 24OHC, MMP-10, MMP-2, and 8OHdG constituted the most relevant and minimally correlated set of variables differentiating AD from CU-N. Interestingly, factor analysis showed that two markers of metabolism and oxidative stress (24OHC and 8OHdG) contributed independent information separate from MMP-10 and FABP3 suggestive of two independent pathophysiological pathways in AD, one reflecting neurodegeneration and vascular pathology, and the other associated with metabolism and oxidative stress. DISCUSSION: Better understanding of the heterogeneity among individuals with AD and the different contributions of pathophysiological processes besides amyloid-ß and tau will be crucial for optimizing personalized treatment strategies. Highlights: A panel of 25 highly validated biomarker assays were measured in CSF.MMP10, FABP3, and 8OHdG were increased in AD in univariate analysis.Many individuals with AD had increased levels of more than one biomarker.Markers of metabolism and oxidative stress contributed to an AD multianalyte profile.Assessing multiple biomarker domains is important to understand disease heterogeneity.

Older adults' name-face association learning is facilitated for names with high-frequency first syllables.

Older adults have even greater difficulty learning name-face associations than young adults, although many variables reflecting properties of the names have been shown to affect young and older adults' name learning similarly. Older adults' name-face association learning was compared for names with high-frequency (HF) first syllables versus names with low-frequency (LF) first syllables. Twenty-eight adults ages 65 to 80 learned five names with HF first syllables and five names with LF first syllables in association with 10 new faces over repeated testing rounds with feedback. Participants learned more name-face associations when the names had HF first syllables than LF first syllables. Findings indicate that older adults benefit from increased frequency of phonological segments within a word on a task other than word retrieval and are consistent with a theoretical framework that accounts for learning new name-face associations, the effects of linguistic properties of the names, and ageing.

The Association of eHealth Literacy Skills and mHealth Application Use Among US Adults With Obesity: Analysis of Health Information National Trends Survey Data.

BACKGROUND: Physical inactivity and a poor diet are modifiable behaviors that contribute to obesity. Obesity is a well-recognized risk factor for chronic diseases, including diabetes. Mobile health (mHealth) apps can play an important adjuvant role in preventing and treating chronic diseases and promoting positive health behavior change among people with obesity, and eHealth literacy skills have the potential to impact mHealth app use. OBJECTIVE: The purpose of this study was to explore the associations between the 2 dimensions, access and application, of eHealth literacy skills and mHealth app use among US adults (≥18 years of age) with obesity (BMI ≥30 kg/m2). METHODS: Data were obtained from February to June 2020 using the Health Information National Trends Survey 5. A total of 1079 respondents met the inclusion criteria of adults with obesity and owners of smartphones. Individual associations between mHealth app use and sociodemographic variables were explored using weighted chi-square and 2-tailed t tests. A multivariable weighted logistic regression model was fitted, and adjusted odds ratios (ORs) of using mHealth apps with corresponding 95% CIs were reported across multiple sociodemographic variables. An Ising model-weighted network visualization was produced. A receiver operating characteristic curve was calculated, and the area under the curve was reported with the corresponding Delong 95% CI. RESULTS: A majority of respondents were female (550/923, 59.6%) or non-Hispanic White (543/923, 58.8%). Individuals in households earning less than US $50,000 comprised 41.4% (382/923) of the sample. All sociodemographic variables were found to be univariately significant at the 5% level, except employment and region. Results from the multivariable weighted logistic regression model showed that the adjusted odds of using an mHealth app are 3.13 (95% CI 1.69-5.80) and 2.99 (95% CI 1.67-5.37) times higher among those with an access eHealth literacy skill of using an electronic device to look for health or medical information for themselves and an application eHealth literacy skill of using electronic communications with a doctor or doctor's office, respectively. Several sociodemographic variables were found to be significant, such as education, where adjusted ORs comparing subgroups to the lowest educational attainment were substantial (ORs ≥7.77). The network visualization demonstrated that all eHealth literacy skills and the mHealth app use variable were positively associated to varying degrees. CONCLUSIONS: This work provides an initial understanding of mHealth app use and eHealth literacy skills among people with obesity, identifying people with obesity subpopulations who are at risk of a digital health divide. Future studies should identify equitable solutions for people with obesity (as well as other groups) and their use of mHealth apps.

Perception of Specific Musical Attributes in Dependence of the Insertion Depth of Cochlear Implant Electrodes Using the Montreal Battery of Evaluation of Amusia.

HYPOTHESIS: The insertion angle of the electrode array has an influence on the perception of different musical features. BACKGROUND: A deeper insertion of the electrodes is associated with a greater coverage of the cochlea with possible stimulus locations. This could lead to an improved or extended perception of pitches and pitch changes as well as to a better perception of contours in musical pieces. METHODS: A Montreal Battery of Evaluation of Amusia test battery was conducted with a collective of 19 cochlear implant (CI) users and 9 normal-hearing subjects. For the CI users, the insertion angles of the intracochlear electrode arrays were calculated using Otoplan software. RESULTS: Compared with normal-hearing users, CI users performed worse in the detection of melodic features of music. CI users performed better with temporal features than with melodic features. An influence of the insertion depth of the electrodes on the results of the Montreal Battery of Evaluation of Amusia could be proven neither for Cochlear nor for MED-EL CI users. CONCLUSION: Deeper insertion of electrode arrays may only better approximate the spatial-frequency map. Alone, it does not have an effect on better detection and identification of pitch and tonality and, consequently, better perception of musical attributes. Anatomy-based calculation of electrode locations and matching to characteristic frequencies will be sought in subsequent studies.

Long-Acting Reversible Contraception Initiation Among Adolescents After an American Academy of Pediatrics Policy Statement.

This cross-sectional study compares monthly rates of long-acting reversible contraception (LARC) insertions among adolescents before and after an American Academy of Pediatrics (AAP) policy statement recommending LARC for this age group.

Racial and ethnic disparities in inferior vena cava filter placement for deep vein thrombosis in the United States.

OBJECTIVE: We sought to determine whether racial and ethnic disparities existed in inferior vena cava (IVC) filter (IVCF) placement rates among Black and Latino patients for the treatment of acute proximal lower extremity (LE) deep vein thrombosis (DVT) in the United States from 2016 to 2019. METHODS: We performed a retrospective review of National Inpatient Sample data to identify adult patients with a primary discharge diagnosis of acute proximal LE DVT from January 2016 to December 2019, including self-reported patient race and ethnicity. IVCF placement rates were identified using International Classification of Diseases, 10th revision, codes. Weighted multivariable logistic regression was used to compare IVCF use by race and ethnicity. The regression model was adjusted for patient demographics (ie, sex, primary payer, quartile classification of household income), hospital information (ie, region, location, teaching status, bed size), weekend admission, and clinical characteristics (ie, modified Charlson comorbidity index, hypertension, atrial fibrillation, diabetes mellitus type 2, congestive heart failure, dyslipidemia, coronary artery disease, smoking, obesity, alcohol abuse, chronic kidney disease, pulmonary embolism, malignancy, contraindications to anticoagulation, including other major bleeding). RESULTS: Of 134,499 acute proximal LE DVT patients, 18,909 (14.1%) received an IVCF. Of the patients who received an IVCF, 12,733 were White (67.3%), 3563 were Black (18.8%), and 1679 were Latino (8.9%). IVCF placement decreased for all patient groups between 2016 and 2019. After adjusting for the U.S. population distribution, the IVCF placement rates were 11 to 12/100,000 persons for Black patients, 7 to 8/100,000 persons for White patients, and 4 to 5/100,000 persons for Latino patients. The difference in IVCF placement rates was statistically significant between patient groups (Black patients vs White patients, P < .05; Black patients vs Latino patients, P < .05; Latino patients vs White patients, P < .05). CONCLUSIONS: This nationwide study showed that Black patients have higher IVCF placement rates compared with White and Latino patients. Given the known long-term complications and uncertain benefits of IVCFs, coupled with the 2010 U.S. Food and Drug Administration safety warning regarding adverse patient events for these devices, proactive measures should be taken to address this disparity among the Black patient population to promote health equity. Future work should assess whether clinician bias might be perpetuating this disparity.
