RESUMEN

Background: Inpatient monitoring is recommended for sotalol initiation. Objective: The purpose of this study was to assess the safety of outpatient sotalol commencement. Methods: This is a multicenter, retrospective, observational study of patients initiated on sotalol in an outpatient setting. Serial electrocardiogram monitoring at day 3, day 7, 1 month, and subsequently as clinically indicated was performed. Corrected QT (QTc) interval and clinical events were evaluated. Results: Between 2008 and 2023, 880 consecutive patients who were commenced on sotalol were evaluated. Indications were atrial fibrillation/flutter in 87.3% (n = 768), ventricular arrhythmias in 9.9% (n = 87), and other arrhythmias in 2.8% (n = 25). The daily dosage at initiation was 131.0 ± 53.2 mg/d. The QTc interval increased from baseline (431 ± 32 ms) to 444 ± 37 ms (day 3) and 440 ± 33 ms (day 7) after sotalol initiation (P < .001). Within the first week, QTc prolongation led to the discontinuation of sotalol in 4 and dose reduction in 1. No ventricular arrhythmia, syncope, or death was observed during the first week. Dose reduction due to asymptomatic bradycardia occurred in 3 and discontinuation due to dyspnea in 3 within the first week. Overall, 1.1% developed QTc prolongation (>500 ms/>25% from baseline); 4 within 3 days, 1 within 1 week, 4 within 60 days, and 1 after >3 years. Discontinuation of sotalol due to other adverse effects occurred in 41 patients within the first month of therapy. Conclusion: Sotalol initiation in an outpatient setting with protocolized follow-up is safe, with no recorded sotalol-related mortality, ventricular arrhythmias, or syncope. There was a low incidence of significant QTc prolongation necessitating discontinuation within the first month of treatment. Importantly, we observed a small incidence of late QT prolongation, highlighting the need for vigilant outpatient surveillance of individuals on sotalol.

RESUMEN

The shortest distance around the Universe through us is unlikely to be much larger than the horizon diameter if microwave background anomalies are due to cosmic topology. We show that observational constraints from the lack of matched temperature circles in the microwave background leave many possibilities for such topologies. We evaluate the detectability of microwave background multipole correlations for sample cases. Searches for topology signatures in observational data over the large space of possible topologies pose a formidable computational challenge.

RESUMEN

Introduction: Many patients with chronic obstructive pulmonary disease (COPD) may derive inadequate benefit from dry powder inhalers (DPIs) because of suboptimal peak inspiratory flow (sPIF). Objectives: To assess the clinical burden of COPD by characterizing the clinical characteristics of participants with sPIF against medium-low resistance DPIs versus those with optimal PIF (oPIF) from two phase 3 clinical trials. Methods: Baseline data were collected from two randomized, controlled, phase 3 trials (NCT03095456; NCT02518139) in participants with moderate-to-severe COPD. oPIF (60 L/min) against the medium-low resistance DPIs was used as the threshold for defining the PIF subgroups (<60 L/min (sPIF) vs ≥60 L/min (oPIF)). Results: Most participants included in this analysis were White (92%) and male (63%); the mean (range) age was 65 (43-87) years. Participants with sPIF had significantly greater dyspnea than those with oPIF as measured using the modified Medical Research Council scoring (mean (95% CI): 2.1 (2.0-2.2) vs 1.6 (1.4-1.7); P < 0.001) and baseline dyspnea index (mean (95% CI): 5.1 (4.9-5.4) vs 6.1 (5.8-6.3); P < 0.001). Based on COPD Assessment Test scores, participants with sPIF had a higher COPD symptom burden than those with oPIF (mean (95% CI): 21.5 (19.7-23.3) vs 19.5 (18.6-20.4); P = 0.05). Conclusion: In these trials, participants with COPD who had sPIF against the medium-low resistance DPIs had more dyspnea and worse health status than those with oPIF. These results demonstrate that sPIF is associated with a higher clinical burden as measured by patient-reported outcomes.

RESUMEN

BACKGROUND: Mohs micrographic surgery efficiently treats skin cancer through staged resection, but surgeons' varying resection rates may lead to higher medical costs. OBJECTIVE: To evaluate the cost savings associated with a quality improvement. MATERIALS AND METHODS: The authors conducted a retrospective cohort study using 100% Medicare fee-for-service claims data to identify the change of mean stages per case for head/neck (HN) and trunk/extremity (TE) lesions before and after the quality improvement intervention from 2016 to 2021. They evaluated surgeon-level change in mean stages per case between the intervention and control groups, as well as the cost savings to Medicare over the same time period. RESULTS: A total of 2,014 surgeons performed Mohs procedures on HN lesions. Among outlier surgeons who were notified, 31 surgeons (94%) for HN and 24 surgeons (89%) for TE reduced their mean stages per case with a median reduction of 0.16 and 0.21 stages, respectively. Reductions were also observed among outlier surgeons who were not notified, reducing their mean stages per case by 0.1 and 0.15 stages, respectively. The associated total 5-year savings after the intervention was 92 million USD. CONCLUSION: The implementation of this physician-led benchmarking model was associated with broad reductions of physician utilization and significant cost savings.

RESUMEN

The purpose of this study was to test whether the psychological inertia process believed to give rise to crime continuity is limited to aggressive delinquency or evolves from both aggressive and nonaggressive delinquency. Self-report data provided by 845 early adolescent youth (406 boys, 439 girls) were analyzed in an effort to test the hypothesis that aggressive rather than nonaggressive delinquency precipitates a rise in delinquency through the intervening influence of cognitive impulsivity but not moral neutralization. The hypothesis stated that of the four models evaluated in this study (aggressive delinquency → moral neutralization → offense variety; aggressive delinquency → cognitive impulsivity → offense variety; nonaggressive delinquency → moral neutralization → offense variety; nonaggressive delinquency → cognitive impulsivity → offense variety), only the aggressive delinquency → cognitive impulsivity → offense variety model would achieve significance. Consistent with this hypothesis, only the aggressive delinquency → cognitive impulsivity → offense variety pathway was, in fact, significant. The current findings suggest that the psychological inertia process may be driven by a pattern of aggressive delinquency followed by cognitive impulsivity and that neither nonaggressive delinquency nor moral neutralization contribute to the process. Theoretical and practical implications of these results are discussed.

RESUMEN

AIMS: To evaluate the clinical safety, tolerability, and pharmacokinetic and pharmacodynamic profile of the novel cannabinoid receptor-1 (CB1R) inverse agonist, INV-202, in adults with features of metabolic syndrome. MATERIALS AND METHODS: This was a multicentre, randomized, double-blind, placebo-controlled, 28-day repeat-dose (INV-202 [25 mg] or placebo, once-daily oral tablet), parallel-group study in 37 participants aged 18 to 65 years (46% female, mean age 55 years, glycated haemoglobin 5.7% [39 mmol/mol], body mass index [BMI] 38.1 kg/m2 ) with features of metabolic syndrome and glucose intolerance. An oral glucose tolerance test (OGTT) was performed at baseline and at the end of the study. Lipid profiles, weight, waist circumference and biomarkers were assessed weekly. Statistical comparisons were performed post hoc. RESULTS: INV-202 was well tolerated with no serious or severe treatment-emergent adverse events; the most common events related to known effects of CB1R blockade in the gastrointestinal tract. INV-202 produced a significant mean weight loss of 3.5 kg (3.3% compared with placebo participants who gained a mean 0.6 kg [0.5%]). INV-202 also exhibited significant reductions in waist circumference and BMI (P ≤ 0.03). There was no significant difference in OGTT 0- to 3-hour area under the curve for INV-202 versus placebo: least squares mean 29.38 versus 30.25 h*mmol/L, with an INV-202: placebo ratio of 97.1% (95% confidence interval 90.2, 105.6; P = 0.43). CONCLUSIONS: INV-202 was well tolerated, producing a signal for rapid weight loss with improvements in other metabolic syndrome markers in this population. These findings support further exploration and long-term assessment of cardiometabolic effects.

RESUMEN

Diabetic cardiomyopathy describes heart disease in patients with diabetes who have no other cardiac conditions but have a higher risk of developing heart failure. Specific therapies to treat the diabetic heart are limited. A key mechanism involved in the progression of diabetic cardiomyopathy is dysregulation of cardiac energy metabolism. The aim of this study was to determine if increasing the expression of medium-chain acyl-coenzyme A dehydrogenase (MCAD; encoded by Acadm), a key regulator of fatty acid oxidation, could improve the function of the diabetic heart. Male mice were administered streptozotocin to induce diabetes, which led to diastolic dysfunction 8 weeks post-injection. Mice then received cardiac-selective adeno-associated viral vectors encoding MCAD (rAAV6:MCAD) or control AAV and were followed for 8 weeks. In the non-diabetic heart, rAAV6:MCAD increased MCAD expression (mRNA and protein) and increased Acadl and Acadvl, but an increase in MCAD enzyme activity was not detectable. rAAV6:MCAD delivery in the diabetic heart increased MCAD mRNA expression but did not significantly increase protein, activity, or improve diabetes-induced cardiac pathology or molecular metabolic and lipid markers. The uptake of AAV viral vectors was reduced in the diabetic versus non-diabetic heart, which may have implications for the translation of AAV therapies into the clinic. KEY MESSAGES: The effects of increasing MCAD in the diabetic heart are unknown. Delivery of rAAV6:MCAD increased MCAD mRNA and protein, but not enzyme activity, in the non-diabetic heart. Independent of MCAD enzyme activity, rAAV6:MCAD increased Acadl and Acadvl in the non-diabetic heart. Increasing MCAD cardiac gene expression alone was not sufficient to protect against diabetes-induced cardiac pathology. AAV transduction efficiency was reduced in the diabetic heart, which has clinical implications.

RESUMEN

BACKGROUND: Amid a movement toward value-based healthcare, increasing emphasis has been placed on outcomes and cost of medical services. To define and demonstrate the quality of services provided by Mohs surgeons, it is important to identify and understand the key aspects of Mohs micrographic surgery (MMS) that contribute to excellence in patient care. OBJECTIVE: The purpose of this study is to develop and identify a comprehensive list of metrics in an initial effort to define excellence in MMS. METHODS: Mohs surgeons participated in a modified Delphi process to reach a consensus on a list of metrics. Patients were administered surveys to gather patient perspectives. RESULTS: Twenty-four of the original 66 metrics met final inclusion criteria. Broad support for the initiative was obtained through physician feedback. LIMITATIONS: Limitations of this study include attrition bias across survey rounds and participation at the consensus meeting. Furthermore, the list of metrics is based on expert consensus instead of quality evidence-based outcomes. CONCLUSION: With the goal of identifying metrics that demonstrate excellence in performance of MMS, this initial effort has shown that Mohs surgeons and patients have unique perspectives and can be engaged in a data-driven approach to help define excellence in the field of MMS.

RESUMEN

BACKGROUND: There is a paucity of data comparing periprosthetic hip fracture (PPHFx) outcomes and resource utilization to native fractures. Many surgeons consider periprosthetic hip fractures to be more severe injuries than native fractures. The aim of this systematic review is to characterize the outcomes of PPHFx and assess their severity relative to native hip fractures (NHFx). METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-Analysis systematic review was conducted using Medline, Biosis, and Cinahl. Primary outcomes were time to surgery, length of stay (LOS), cost of management, disposition, complication rates, readmission rates, and mortality. RESULTS: 14 articles (13,489 patients) from 2010 to 2018 were included in the study. Study quality was generally low. Patient follow-up ranged from 1 month to 3.2 years. LOS ranged from 5.2 to 38 days. US cost of management was best estimated at $53,669 ± 19,817. Discharge to skilled nursing facilities ranged from 64.5 to 74.5%. Time to surgery ranged from 1.9 to 5.7 days. Readmission rates ranged from 12 to 32%. Per Clavien-Dindo classification, 33.9% suffered minor complications; 14.3% suffered major complications. 1 month and 1 year mortality ranged from 2.9% to 10% and 9.7% to 45%, respectively. CONCLUSION: Time to surgery and LOS were longer for PPHFx relative to NHFx. Complications' rates were higher for PPHFx compared to NHFx. There is no evidence for differences in LOS, cost, discharge, readmission rates, or mortality between PPHFx and NHFx. These results may serve as a baseline in future evaluation of PPHFx management.

RESUMEN

OBJECTIVE: Although reciprocity between variables is a topic of interest in the field of criminology, we cannot simply assume that all or even most criminological relationships are bidirectional without testing them empirically. The objective of the current investigation was to test whether delinquency and antisocial cognition are reciprocally or bidirectionally related. HYPOTHESES: The hypotheses evaluated as part of the present study proposed that antisocial cognition would predict delinquency, delinquency would predict antisocial cognition, and bidirectional models would display significantly better fit than the unidirectional models on which they are based. METHOD: Using data from the Pathways to Desistance study (1,354 serious justice-involved youths), I explored whether antisocial cognition predicts delinquency and a change in delinquency and whether delinquency predicts antisocial cognition and a change in antisocial cognition. I paired two forms of antisocial cognition-moral neutralization and cognitive impulsivity-with delinquency to predict a single future outcome with a zero-order correlation and a lagged outcome or change with a partial correlation. RESULTS: Findings showed that 40 out of 40 prospective zero-order correlations and 36 out of 40 prospective partial correlations achieved significance, with moderate and small effect sizes, respectively. Structural equation modeling revealed that the bidirectional models linking moral neutralization to delinquency and cognitive impulsivity to delinquency using lagged outcome measures both achieved significantly better fit than the unidimensional models on which they were based. CONCLUSION: The results of this study are congruent with the conclusion that the relationship between antisocial cognition and delinquency is reciprocal and that antisocial cognition is as much a predictor of delinquency as delinquency is a predictor of antisocial cognition. Thus, both patterns need to be taken into account for the purposes of theory integration in criminology, clinical practice in forensic psychology, and policy implementation in criminal justice.

RESUMEN

Periodontal health is dependent on a symbiotic relationship of the host immune response with the oral microbiota. Pathologic shifts of the microbial plaque elicit an immune response that eventually leads to the recruitment and activation of osteoclasts and matrix metalloproteinases and the eventual tissue destruction that is evident in periodontal disease. Once the microbial stimulus is removed, an active process of inflammatory resolution begins. The goal of this work was to use scRNAseq to demonstrate the unique cellular immune response across three distinct conditions of periodontal health, disease, and resolution using mouse models. Periodontal disease was induced using a ligature model. Resolution was modeled by removing the ligature and allowing the mouse to recover. Immune cells (Cd45+) were isolated from the periodontium and analyzed via scRNAseq. Gene signature shifts across the three conditions were characterized and shown to be largely driven by macrophage and neutrophils during the periodontal disease and resolution conditions. Resolution of periodontal disease was characterized by the differential regulation of unique gene subsets. Clustering analysis characterized multiple cellular subpopulations within B Cells, macrophages, and neutrophils that demonstrated differential expansion and contraction across conditions of periodontal health, disease, and resolution. Interestingly, we identified a transcriptionally distinct macrophage subpopulation that expanded during the resolution condition and demonstrated an immunoregulatory gene signature. We identified a cell surface marker for this resolution-associated macrophage subgroup (Cd74) and validated the expansion of this subgroup during resolution via flow cytometry. This work presents a robust immune cell atlas for study of the immunological changes in the oral mucosa during three distinct conditions of periodontal health, disease, and resolution and it improves our understanding of the cellular and molecular markers that characterize health from disease for the development of future diagnostics and therapies.

RESUMEN

Cardiomyocyte calcium homeostasis is a tightly regulated process. The mitochondrial calcium uniporter (MCU) complex can buffer elevated cytosolic Ca2+ levels and consists of pore-forming proteins including MCU, and various regulatory proteins such as mitochondrial calcium uptake proteins 1 and 2 (MICU1/2). The stoichiometry of these proteins influences the sensitivity to Ca2+ and the activity of the complex. However, the factors that regulate their gene expression remain incompletely understood. Long noncoding RNAs (lncRNAs) regulate gene expression through various mechanisms, and we recently found that the lncRNA Tug1 increased the expression of Mcu and associated genes. To further explore this, we performed antisense LNA knockdown of Tug1 (Tug1 KD) in H9c2 rat cardiomyocytes. Tug1 KD increased MCU protein expression, yet pyruvate dehydrogenase dephosphorylation, which is indicative of mitochondrial Ca2+ uptake, was not enhanced. However, RNA-seq revealed that Tug1 KD increased Mcu along with differential expression of >1,000 genes including many related to Ca2+ regulation pathways in the heart. To understand the effect of this on Ca2+ signaling, we measured phosphorylation of Ca2+/calmodulin-dependent protein kinase II (CaMKII) and its downstream target cAMP Response Element-Binding protein (CREB), a transcription factor known to drive Mcu gene expression. In response to a Ca2+ stimulus, the increase in CaMKII and CREB phosphorylation was attenuated by Tug1 KD. Inhibition of CaMKII, but not CREB, partially prevented the Tug1 KD-mediated increase in Mcu. Together, these data suggest that Tug1 modulates MCU expression via a mechanism involving CaMKII and regulates cardiomyocyte Ca2+ signaling, which could have important implications for cardiac function.NEW & NOTEWORTHY Calcium is essential for signaling, excitation contraction, and energy homeostasis in the heart. Despite this, molecular regulators of these processes are not completely understood. We report that knockdown of lncRNA Tug1 alters the calcium handling transcriptome and increases mitochondrial calcium uniporter expression via a mechanism involving CaMKII. As overexpression of MCU is known to be protective against pathological cardiac remodeling, targeting Tug1 may be a potential strategy for treating cardiovascular disease.

RESUMEN

This study sought to assess whether two scales from a criminal thinking inventory displayed bipolar properties such that high scores on these scales reflect a risk effect and low scores a promotive effect. To test this hypothesis, the proactive criminal thinking (PCT) and reactive criminal thinking (RCT) scales from the Psychological Inventory of Criminal Thinking Styles (PICTS) were organized into three categories-top 25% of scores (high group), the middle 50% of scores (intermediate group), and bottom 25% of scores (low group)-and crossed with preincarceration (prior convictions and age at first conviction), peri-incarceration (total and aggressive institutional infractions), and postincarceration (revocation and rearrest) outcome indicators. Participants for this study were 3,039 male inmates who completed the PICTS while confined in a medium-security federal prison. Results showed that the PCT and RCT each achieved a mixed (risk and promotive) effect for four out of six outcomes. Of the four unipolar effects, PCT achieved a promotive effect but not a risk effect for the two preincarceration outcomes, whereas RCT produced a risk but not promotive effect for the two postincarceration outcomes. These results provide support for the notion that PCT and RCT are primarily bipolar dimensional constructs in which high scores are associated with negative criminal justice outcomes and low scores with positive criminal justice outcomes, although there may be unipolar aspects to each scale as well.

RESUMEN

We have investigated the effects that partial-sleep-restriction (PSR0, 4-h sleep retiring at 02:30 and waking at 06:30 h for two consecutive nights) have on 07:30 and 17:00 h cognitive and submaximal weightlifting; and whether this performance improves at 17:00 h following a 13:00 h powernap (0, 30 or 60-min). Fifteen resistance-trained males participated in this study. Prior to the experimental protocol, one repetition max (1RM) bench press and back squat, normative habitual sleep and food intake were recorded. Participants were familiarised with the testing protocol, then completed three experimental conditions: (i) PSR with no nap (PSR0); (ii) PSR with a 30-min nap (PSR30) and (iii) PSR with a 60-min nap (PSR60). Conditions were separated by 7 days with trial order counterbalanced. Intra-aural temperature, Profile of Mood Scores, word-colour interference, alertness and tiredness values were measured at 07:30, 11:00, 14:00, 17:00 h on the day of exercise protocol. Following final temperature measurements at 07:30 h and 17:00 h, participants completed a 5-min active warm-up before performing three repetitions of left and right-hand grip strength, followed by three repetitions at each incremental load (40, 60 and 80% of 1RM) for bench press and back squat, with a 5-min recovery between each repetition. A linear encoder was attached perpendicular to the bar used for the exercises. Average power (AP), average velocity (AV), peak velocity (PV), displacement (D) and time-to-peak velocity (tPV) were measured (MuscleLab software) during the concentric phase of the movements. Data were analysed using general linear models with repeated measures. The main findings were that implementing a nap at 13:00 h had no effect on measures of strength (grip, bench press or back squat). There was a main effect for time of day with greatest performance at 17:00 h for measures of strength. In addition to a significant effect for "load" on the bar for bench press and back squat where AP, AV, PV, D values were greatest at 40% (P < 0.05) and decreased with increased load, whereas tPV and RPE values increased with load; despite this no interaction of "load and condition" were present. A post lunch nap of 30- and 60-minute durations improved mood state, with feelings of alertness, vigour and happiness highest at 17:00 h, in contrast to confusion, tiredness and fatigue (P < 0.05), which were greater in the morning (07:30 h). The word-colour interference test, used as an indicator of cognitive function, reported significant main effect for condition, with the highest total test score in PSR60 condition (P = 0.015). In summary, unlike strength measures the implementation of a 30 or 60-minute nap improved cognitive function when in a partially sleep restricted state, compared to no nap.

RESUMEN

OBJECTIVE: To determine changes in opioid prescribing among veterans with headaches during the coronavirus disease of 2019 (COVID-19) pandemic by comparing the stay-at-home phase (March 15 to May 30, 2020) and the reopening phase (May 31 to December 31, 2020). BACKGROUND: Opioid prescribing for chronic pain has declined substantially since 2016; however, changes in opioid prescribing during the COVID-19 pandemic among veterans with headaches remain unknown. METHODS: This retrospective cohort study utilized regression discontinuity in time and difference-in-differences design to analyze veterans aged ≥18 years with a previous diagnosis of headache disorders and an outpatient visit to the Veterans Health Administration (VHA) during the study period. We measured the weekly number of opioid prescriptions, the number of days supplied, the daily dose in morphine milligram equivalents (MMEs), and the number of prescriptions with ≥50 morphine equivalent daily doses (MEDD). RESULTS: A total of 81,376 veterans were analyzed with 589,950 opioid prescriptions. The mean (SD) age was 51.6 (13.5) years, 57,242 (70.3%) were male, and 53,464 (65.7%) were White. During the pre-pandemic period, 323.6 opioid prescriptions (interquartile range 292.1-325.8) were dispensed weekly, with an median (IQR) of 24.1 (24.0-24.4) days supplied and 31.8 (31.2-32.5) MMEs. Transition to stay-at-home was associated with a 7.7% decrease in the number of prescriptions (incidence rate ratio [IRR] 1.077, 95% confidence interval [CI] 0.866-0.984) and a 9.8% increase in days supplied (IRR 1.098, 95% CI 1.078-1.119). Similar trends were observed during the reopening period. Subgroup analysis among veterans on long-term opioid therapy also revealed 1.7% and 1.4% increases in days supplied during the stay-at-home (IRR 1.017, 95% CI 1.009-1.025) and reopening phase (IRR 1.014, 95% CI 1.007-1.021); however, changes in the total number of prescriptions, MME/day, or the number of prescriptions >50 MEDD were insignificant. CONCLUSION: Prescription opioid access was maintained for veterans within VHA during the pandemic. The de-escalation of opioid prescribing observed prior to the pandemic was not seen in our study.

RESUMEN

Translational impact assessment is key to selecting those biomedical research discoveries most likely to be converted into viable new products to improve human health. However, metrics for translational success are variable, are not limited to commercial success, and may not be relevant to every case or institution. Societal impact is a top translational priority in a globalized society.
