RESUMEN
Pulmonary balloon valvuloplasty (PBV) is the treatment of choice for subjects with isolated pulmonary valve stenosis (IPS). The purpose of this study was to define fetal echocardiographic features associated with an inpatient PBV prior to newborn hospital discharge and characterize resource utilization of IPS fetuses among participating centers. Six center, retrospective case series of singleton fetuses identified between 2010 and 2020 with IPS. Third-trimester echocardiogram data was compared with postnatal data, included pulmonary valve Doppler velocities, pulmonary valve insufficiency and ductus arteriosus flow direction. Comparison between subjects who underwent inpatient PBV during their newborn hospital admission versus those infants referred for outpatient PBV after initial hospital discharge. We analyzed data by logistic regression, student t test and Chi-Square testing with a p value of ≤ 0.05 considered statistically significant. Forty-nine IPS fetuses were identified. Thirty-eight (78%) underwent inpatient PBV at 5 (range 1-58) days and 11 (22%) underwent outpatient PBV at 51.8 (11-174) days. Newborns requiring an inpatient PBV were more likely to have one or more characteristics on 3rd-trimester fetal echocardiogram: left to right or bidirectional ductus arteriosus flow (61% vs 0%), and/or a peak pulmonary valve velocity > 3.0 m/s (odds ratio 16.9, 95% confidence interval 3.02-94.17) with a sensitivity of 90.4% and specificity of 97.7%. Ductus arteriosus flow direction and pulmonary valve peak velocity in the 3rd trimester can successfully predict the need for newborn inpatient PBV. We speculate these findings may be useful in choosing delivery site for the pregnancy complicated by fetal IPS.

Researchers have demonstrated associations between use of pornography and sexual objectification of women. We examine whether self-reported preference for degrading pornography moderated the relation between use frequency and sexual objectification of others. Participants were 1,342 heterosexual women and men residing in the United States. In women and men, pornography use frequency was associated with the sexual objectification of others, even after controlling for interest in generally explicit content. In men, interest in degrading pornography content significantly predicted sexual objectification of women. Our results suggest greater pornography use is associated with greater sexual objectification of others, across a variety of content categories.

More than 1 in 5 pregnant people in the United States experience depressive symptoms. Although treatments exist, many people remain under- or un-treated due to concerns about stigma, side effects, and costs of medications or psychotherapy, particularly those who are marginalized (defined as those who are minoritized, low-income, or with low-educational attainment). Further, the standard depression treatments do not address social connectedness, which is a potentially modifiable factor involved in depressive symptom etiology. This protocol presents the rationale, design, and status of the two-arm longitudinal parallel group randomized controlled trial - the Mindful Moms Study - which aims to evaluate the effects and mechanisms of a group-based mindful physical activity (yoga) intervention in marginalized pregnant people with depressive symptoms (n = 200) compared to a prenatal education control group. The primary aim is to evaluate effects of group assignment on depressive symptom severity, anxiety, and perceived stress over time from baseline to six weeks postpartum. Secondary aims include understanding the role of social connectedness as a moderator of the effects and to identify genome-wide DNA methylation patterns associated with depressive symptoms and perceived social connectedness at postpartum. A focus on adequate symptom management through non-pharmacologic, accessible therapies that address social connectedness during pregnancy in marginalized women is an urgent clinical and research priority. The successful completion of this study will provide important insights into social connectedness as a mechanism to decrease depressive symptoms in a largely understudied population. Trial registration: NCT04886856.

BACKGROUND: Cotesting with the Papanicolaou (Pap) and human papillomavirus tests detects most precancerous and cancerous lesions and increases the sensitivity for detecting high-grade precancerous and invasive cervical cancers compared with human papillomavirus testing alone. OBJECTIVE: To compare the use of the Papette brush (hereafter Papette) to the traditional spatula with endocervical brush (cytobrush) for cervical cancer screening. DESIGN: Pragmatic observational study. METHODS: Adult women aged 21-64 years who were eligible for a Papanicolaou test at a Midwest Community Internal Medicine practice underwent cervical cancer screening using the Papette or spatula with cytobrush from 18 August 2021 through 1 February 2022. Cluster sampling was used across the practice. Pathology reports were then analyzed to compare the number of satisfactory versus unsatisfactory results between the two collection techniques. RESULTS: We collected results for 756 Pap tests. The test results were satisfactory with the Papette 93.8% of the time compared with 93.0% for the spatula with cytobrush. CONCLUSION: The Papette is not inferior to a spatula with cytobrush as a collection method for Pap tests.

Ebstein anomaly is the most common form of tricuspid valve congenital anomalies. The tricuspid valve is abnormal with different degrees of displacement of the septal leaflet and abnormal rotation of the valve towards the right ventricular outflow tract. In severe forms, it results in significant tricuspid regurgitation and requires surgical repair. There is an increased interest in understanding the anatomy of the tricuspid valve in this lesion as the surgical repair has evolved with the invention and wide adoption of the cone operation. Multimodality imaging plays an important role in diagnosis, follow-up, surgical planning and post-operative care. This review provides anatomical tips for the cardiac imagers caring for patients with Ebstein anomaly and will help provide image-based personalized medicine.

Objective: Term congenital heart disease (CHD) neonates display abnormalities of brain structure and maturation, which are possibly related to underlying patient factors, abnormal physiology and perioperative insults. Our primary goal was to delineate associations between clinical factors and postnatal brain microstructure in term CHD neonates using diffusion tensor imaging (DTI) magnetic resonance (MR) acquisition combined with complementary data-driven connectome and seed-based tractography quantitative analyses. Our secondary goal was to delineate associations between mild dysplastic structural brain abnormalities and connectome and seed-base tractography quantitative analyses. These mild dysplastic structural abnormalities have been derived from prior human infant CHD MR studies and neonatal mouse models of CHD that were collectively used to calculate to calculate a brain dysplasia score (BDS) that included assessment of subcortical structures including the olfactory bulb, the cerebellum and the hippocampus. Methods: Neonates undergoing cardiac surgery for CHD were prospectively recruited from two large centers. Both pre- and postoperative MR brain scans were obtained. DTI in 42 directions was segmented into 90 regions using a neonatal brain template and three weighted methods. Clinical data collection included 18 patient-specific and 9 preoperative variables associated with preoperative scan and 6 intraoperative (e.g., cardiopulmonary bypass and deep hypothermic circulatory arrest times) and 12 postoperative variables associated with postoperative scan. We compared patient specific and preoperative clinical factors to network topology and tractography alterations on a preoperative neonatal brain MRI, and intra and postoperative clinical factors to network topology alterations on postoperative neonatal brain MRI. A composite BDS was created to score abnormal findings involving the cerebellar hemispheres and vermis, supratentorial extra-axial fluid, olfactory bulbs and sulci, hippocampus, choroid plexus, corpus callosum, and brainstem. The neuroimaging outcomes of this study included (1) connectome metrics: cost (number of connections) and global/nodal efficiency (network integration); (2) seed based tractography methods of fractional anisotropy (FA), radial diffusivity, and axial diffusivity. Statistics consisted of multiple regression with false discovery rate correction (FDR) comparing the clinical risk factors and BDS (including subcortical components) as predictors/exposures and the global connectome metrics, nodal efficiency, and seed based- tractography (FA, radial diffusivity, and axial diffusivity) as neuroimaging outcome measures. Results: A total of 133 term neonates with complex CHD were prospectively enrolled and 110 had analyzable DTI. Multiple patient-specific factors including d-transposition of the great arteries (d-TGA) physiology and severity of impairment of fetal cerebral substrate delivery (i.e., how much the CHD lesion alters typical fetal circulation such that the highest oxygen and nutrient rich blood from the placenta are not directed toward the fetal brain) were predictive of preoperative reduced cost (p < 0.0073) and reduced global/nodal efficiency (p < 0.03). Cardiopulmonary bypass time predicted postoperative reduced cost (p < 0.04) and multiple postoperative factors [extracorporeal membrane oxygenation (ECMO), seizures and cardiopulmonary resuscitation (CPR)] were predictive of postoperative reduced cost and reduced global/nodal efficiency (p < 0.05). Anthropometric measurements (weight, length, and head size) predicted tractography outcomes. Total BDS was not predictive of brain network topology. However, key subcortical components of the BDS score did predict key global and nodal network topology: abnormalities of the cerebellum predicted reduced cost (p < 0.0417) and of the hippocampus predicted reduced global efficiency (p < 0.0126). All three subcortical structures predicted unique alterations of nodal efficiency (p < 0.05), including hippocampal abnormalities predicting widespread reduced nodal efficiency in all lobes of the brain, cerebellar abnormalities predicting increased prefrontal nodal efficiency, and olfactory bulb abnormalities predicting posterior parietal-occipital nodal efficiency. Conclusion: Patient-specific (d-TGA anatomy, preoperative impairment of fetal cerebral substrate delivery) and postoperative (e.g., seizures, need for ECMO, or CPR) clinical factors were most predictive of diffuse postnatal microstructural dysmaturation in term CHD neonates. Anthropometric measurements (weight, length, and head size) predicted tractography outcomes. In contrast, subcortical components (cerebellum, hippocampus, olfactory) of a structurally based BDS (derived from CHD mouse mutants), predicted more localized and regional postnatal microstructural differences. Collectively, these findings suggest that brain DTI connectome and seed-based tractography are complementary techniques which may facilitate deciphering the mechanistic relative contribution of clinical and genetic risk factors related to poor neurodevelopmental outcomes in CHD.
RESUMEN
There are limited data for the clinical efficacy of bebtelovimab in preventing severe coronavirus disease 2019. Among outpatients unable to take nirmatrelvir-ritonavir at a large health system, 10 of 377 (2.7%) patients who received bebtelovimab and 17 of 377 (4.5%) matched untreated patients were hospitalized or died. The 43% observed risk reduction with bebtelovimab was not statistically significant (P = 0.14).

BACKGROUND/OBJECTIVES: In children, distinguishing anogenital warts (AGW) acquired innocently from those acquired by child sexual abuse (CSA) is challenging. High-quality studies examining this relationship are sparse. Here, we sought to evaluate the association between AGW and sexual abuse in children 12 years of age and younger with respect to wart location, age, and gender. METHODS: A systematic review of Ovid MEDLINE, Embase, and Web of Science was performed for studies published on or before 2/16/2018. Studies were eligible for inclusion if they contained at least 10 patients 12 years old and younger and reported the number of patients who were sexually abused. The principal summary measures were the odds ratios (OR) of reported CSA with respect to subject age, wart location, and gender. RESULTS: Three hundred twenty-seven studies were identified through record search. Twenty five were included in a summary synthesis (791 subjects); 10 were included in the final statistical analysis (199 subjects). In our overall review, 102 of 468 (21%) females and 36 of 204 (18%) males with AGW were abused or probably abused. Overlapping HPV types were found in abused and non-abused subjects. Perianal location and gender were not significant predictors of abuse. Both age and genital wart location (penis, vulva) did significantly predict CSA (α = .05). The odds ratio for sexual abuse of children aged 3-4 years was 7.45; 6.52 for ages 5-8 years; and 6.93 for ages 9-12 years compared to those 0-2 years of age. Genital location was associated with an OR of CSA of 5.93. CONCLUSIONS: Our systematic review supports a significant association between AGW in a child greater than 2 years of age and odds of CSA. Genital wart location significantly predicts CSA as well. HPV typing is not a reliable method to ascertain CSA. Male family members and acquaintances were the most likely perpetrators of abuse.

BACKGROUND: Research is limited on combining outpatient parenteral antimicrobial therapy (OPAT) with addiction treatment for people who inject drugs (PWID) with serious infections. METHODS: This is a retrospective study of PWID (nâ =â 68) requiring intravenous antibiotics evaluated for suitability for our OPAT program with concurrent addiction treatment. RESULTS: Most common infections were bacteremia and/or endocarditis (73.5%), bone and/or joint infections (32.4%), and epidural abscess (22.1%). Of the 20 patients (29.4%) who qualified, 100.0% completed the course of antibiotics, 30.0% experienced a 30-day readmission, and 15.0% relapsed. No overdoses, deaths, or peripherally inserted central catheter-line complications were reported. CONCLUSIONS: Outpatient parenteral antimicrobial therapy with addiction treatment may be feasible and safe for PWID with serious infections.

This review assesses the current state of knowledge of how the elements were produced in the Big Bang, in stellar lives and deaths, and by interactions in interstellar gas. We begin with statements of fact and discuss the evidence that convinced astronomers that the Sun is fusing hydrogen, that low-mass stars produce heavy elements through neutron capture, that massive stars can explode as supernovae and that supernovae of all types produce new elements. Nucleosynthesis in the Big Bang, through cosmic ray spallation, and in exploding white dwarfs is only ranked below the above facts in certainty because the evidence, while overwhelming, is so far circumstantial. Next, we highlight the flaws in our current understanding of the predictions for lithium production in the Big Bang and/or its destruction in stars and for the production of the elements with atomic number [Formula: see text]. While the theory that neutron star mergers produce elements through neutron-capture has powerful circumstantial evidence, we are unconvinced that they produce all of the elements past nickel. Also in dispute is the exact mechanism or mechanisms that cause the white dwarfs to explode. It is difficult to determine the origin of rare isotopes because signatures of their production are weak. We are uncertain about the production sites of some lithium and nitrogen isotopes and proton-rich heavy nuclei. Finally, Betelgeuse is probably not the next star to become a supernovae in the Milky Way, in part because Betelgeuse may collapse directly to a black hole instead. The accumulated evidence in this review shows that we understand the major production sites for the elements, but islands of uncertainty in the periodic table exist. Resolving these uncertainties requires in particular understanding explosive events with compact objects and understanding the nature of the first stars and is therefore primed for new discoveries in the next decades. This article is part of the theme issue 'Mendeleev and the periodic table'.
RESUMEN
Van den Heuvel and Tauris argue that if the red giant star in the system 2MASS J05215658+4359220 has a mass of 1 solar mass (M â), then its unseen companion could be a binary composed of two 0.9 M â stars, making a triple system. We contend that the existing data are most consistent with a giant of mass [Formula: see text] M â, implying a black hole companion of [Formula: see text] M â.
RESUMEN
Rates of pornography consumption in the U.S. are high and increasing. With exploratory aims, this study addresses the questions: What is the association between pornography consumption and liking of sexual behaviors commonly depicted in pornography, and is enjoyment moderated by gender? Sexual scripts theory suggests that increased pornography consumption is associated with increased engagement in pornographic sex acts, but it does not speak to enjoyment of the acts when engaged. The current study seeks to fill that gap. Based on data collected from a larger sample of 1,883 heterosexual men and women (predominantly, 86.6%, college or university students) in the U.S., and comparing correlations between pornography consumption (frequency of use) and reported enjoyment of a range of sexual behaviors by gender using Fisher's z transformations (α value set at <.0025), analysis revealed that pornography consumption, overall, was not significantly correlated with increased enjoyment of the sexual acts that comprise the pornographic sexual script. However, gender was a significant moderating factor in the enjoyment, specifically, of degrading and/or uncommon acts. Male respondents were significantly more likely to report enjoying these acts than their female counterparts. These findings have possible implications for consumers, educators, and mental health professionals.

BACKGROUND AND OBJECTIVES: The impact of medications for opioid use disorder (MOUD) on against medical advice (AMA) discharges among people who inject drugs (PWID) hospitalized for endocarditis is unknown. METHODS: A retrospective review of all PWID hospitalized for endocarditis at our institution between 2016 and 2018 (n = 84). RESULTS: PWID engaged with MOUD at admission, compared with those who were not, were less likely to be discharged AMA but this did not reach statistical significance in adjusted analysis (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.033-1.41; P = .11). Among out-of-treatment individuals, newly initiating MOUD did not lead to significantly fewer AMA discharges (OR, 0.98; 95% CI, 0.26-3.7; P = .98). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: PWID hospitalized for endocarditis are at high risk for discharge AMA but more research is needed to understand the impact of MOUD. (Am J Addict 2020;29:155-159).

Peripheral nerves are routinely examined microscopically during the nonclinical safety assessment of therapeutics. In addition to test article-related on- or off-target changes, microscopic changes in peripheral nerves may also be caused by study procedures, such as parenteral test article administration and blood or tissue sampling. We present 2 nonclinical case studies in which nonstandard peripheral nerves had study procedure-related histologic changes. The first case study describes mouse trigeminal nerve changes as a result of blood sampling via retro-orbital sinus puncture. These changes included minimal-to-mild nerve fiber (axonal) degeneration associated with macrophage infiltration. The second case study presents rat brachial plexus changes associated with animal handling and blood sampling. Brachial plexus changes included minimal-to-moderate inflammation, focal hemorrhage, and nerve fiber degeneration. In both cases, the histological changes were morphologically indistinguishable from those that might be due to test article. Therefore, careful consideration of the incidence and severity across groups and a review of study procedures to rule out handling-related nerve damage are essential before identifying a test article-related effect on peripheral nerves. Study design considerations to avoid such procedure-related changes will be discussed, as well as sampling strategies to help distinguish these from test article-related effects.

OBJECTIVES: Infective endocarditis (IE) among people who inject drugs is associated with high rates of mortality and repeat episodes of endocarditis. We sought to report on longer-term clinical outcomes of patients with IE who were offered buprenorphine or methadone treatment for opioid use disorder (OUD) at their initial hospital admission. METHODS: Individuals with OUD hospitalized between 2013 and 2015 with IE were included for the retrospective study. The following data were extracted from the medical record: sociodemographic data, mortality, repeat episodes of endocarditis, and evidence of ongoing buprenorphine and methadone treatment. The impact of medication use on mortality and repeat episode of endocarditis was examined using survival analysis. RESULTS: Overall, 26 individuals were included in the study. The mean duration of follow-up was 45.0 months (SD 7.2, range 34.0-56.0). During the index admission, 8 received buprenorphine, 8 received methadone, and 10 declined medications. During the follow-up period, 4 (15.4%) individuals died and 10 (38.5%) individuals experienced a repeat episode of endocarditis. Survival analysis of mortality (log-rank Pâ=â0.066) and repeat episode of endocarditis (log-rank Pâ=â0.86) comparing those who received buprenorphine, received methadone, and declined medication did not differ significantly. CONCLUSIONS: Initiation of medication treatment alone may not be sufficient to impact long-term mortality and rates of repeat episode of endocarditis. More research is needed to identify optimal treatment strategies for people who inject drugs with IE.
