Increased Formation of Trions and Charged Biexcitons by Above-Gap Excitation in Single-layer WSe.

Two-dimensional semiconductors exhibit pronounced many-body effects and intense optical responses due to strong Coulombic interactions. Consequently, subtle differences in photoexcitation conditions can strongly influence how the material dissipates energy during thermalization. Here, using multiple excitation spectroscopies, we show that a distinct thermalization pathway emerges at elevated excitation energies, enhancing the formation of trions and charged biexcitons in single-layer WSe by up to 2× and 5× , respectively.

Meta-Analysis of Interobserver Agreement in Assessment of Interstitial Lung Disease Using High-Resolution CT.

Background High-resolution CT (HRCT) is central to the assessment of interstitial lung disease (ILD), and accurate classification of disease has important implications for patients. Evaluation of imaging features can be challenging, even for experienced thoracic radiologists. Previous work has provided equivocal evidence on the interpretation of HRCT features at ILD-related imaging.

Regulation of dermal circadian pathways by a novel topical formulation.

Skin health is impacted by a wide range of intrinsic and extrinsic factors (J Dermatol Sci, 2017, 85, 152), including those that impact circadian rhythm, such as sleep disruption (Textbook of Aging Skin, 2016), UV (Biomed Aging Pathol, 2013, 3, 161) and blue light (Int J Cosmet Sci, 2019, 41, 558). Disruption of the skin's endogenous circadian balance, even by a consistently late bedtime, has deleterious effects on multiple measurements of skin health, including hydration, skin barrier protection, microbiome counts and skin regeneration, among others (Clin Cosmet Investig Dermatol, 2022, 15, 1051). Skin repair processes occur at night and help to maintain important aspects of skin health (FEBS Lett, 2021, 595, 2413).

Unenhanced computed tomography as a diagnostic tool in suspected pulmonary hypertension: a retrospective cross-sectional pilot study.

Background: Computed tomography pulmonary angiography (CTPA) has been proposed to be diagnostic for pulmonary hypertension (PH) in multiple studies. However, the utility of the unenhanced CT measurements diagnosing PH has not been fully assessed. This study aimed to assess the diagnostic utility and reproducibility of cardiac and great vessel parameters on unenhanced computed tomography (CT) in suspected pulmonary hypertension (PH).

Rigid Sternal Fixation and Enhanced Recovery for Opioid-Free Analgesia After Cardiac Surgery.

Background: We evaluated the individual contributions of rigid-plate fixation (RPF) and an enhanced recovery protocol (ERP) on postoperative pain, opioid use, and other outcomes after median sternotomy as they were sequentially adopted into practice.

Methods: This single-center, retrospective, case-cohort study compared outcomes between median sternotomy patients (all comers) who underwent operation before implementation of RPF or ERP ("controls"), patients closed with RPF before ERP implementation ("RPF-only"), and patients managed with RPF and ERP during early "RPF+ERP-2020" and late "RPF+ERP-2022" implementation.

Results: The analysis included 608 median sternotomy patients (mean age, 65.

Implementing a Preoperative Anemia Optimization Protocol for Cardiovascular Surgery Patients: A Quality Improvement Project.

Background: Patients with anemia have poorer outcomes following cardiac surgery than do those without anemia. To improve outcomes, the Enhanced Recovery After Surgery cardiac recommendations include optimizing patients' condition, including treating anemia, before surgery.

Local Problem: Despite implementing Enhanced Recovery After Surgery initiatives, a midwestern cardiothoracic surgery group recognized a care gap in preoperative patients with anemia.

Incidence of Hypertriglyceridemia in Patients on Propofol, Clevidipine, or Both.

Background: Propofol and clevidipine (PC) are commonly used in the treatment of critically ill patients. While both medications are lipid emulsions, there is limited evidence concerning the incidence of hypertriglyceridemia (HTG) when these agents are used individually or concurrently.

Objective: The objective of this study is to determine the effects of propofol, clevidipine, or concurrent PC on triglycerides (TGs) and related outcomes in critically ill adults.

Effect of skin tone on the accuracy of the estimation of arterial oxygen saturation by pulse oximetry: a systematic review.

Background: Pulse oximetry-derived oxygen saturation (SpO) is an estimate of true arterial oxygen saturation (SaO). The aim of this review was to evaluate available evidence determining the effect of skin tone on the ability of pulse oximeters to accurately estimate SaO.

Methods: Published literature was screened to identify clinical and non-clinical studies enrolling adults and children when SpO was compared with a paired co-oximetry SaO value.

Impact of pediatric cancer on parents' relationships.

Purpose: Cancer in children leads to changes in family life, which can also affect the stability and quality of the parents' relationships. Studies show that parents' educational level, duration of partnership until diagnosis, child's cancer, and grandparents' relationship stability may influence parental partnership. The aim of this study was to investigate the influence of childhood cancer on the stability and quality of parental relationships in Germany.

Telemedicine Consult for Shortness of Breath Due to Sympathetic Crashing Acute Pulmonary Edema.

Audience: This simulation is appropriate for senior and junior emergency medicine residents.

Introduction: Shortness of breath is a very common presentation in the emergency department and can range from mild to severe as well as a chronic or acute onset. In sympathetic crashing acute pulmonary edema (SCAPE), patients typically present with acute onset of dyspnea occurring within minutes to hours and have significantly elevated blood pressure.

Establishing minimally important differences for cardiac MRI end-points in pulmonary arterial hypertension.

Background: Cardiac magnetic resonance (CMR) is the gold standard technique to assess biventricular volumes and function, and is increasingly being considered as an end-point in clinical studies. Currently, with the exception of right ventricular (RV) stroke volume and RV end-diastolic volume, there is only limited data on minimally important differences (MIDs) reported for CMR metrics. Our study aimed to identify MIDs for CMR metrics based on US Food and Drug Administration recommendations for a clinical outcome measure that should reflect how a patient "feels, functions or survives".

Genome-wide association identifies key loci controlling blackberry postharvest quality.

Introduction: Blackberry ( subgenus ) is a soft-fruited specialty crop that often suffers economic losses due to degradation in the shipping process. During transportation, fresh-market blackberries commonly leak, decay, deform, or become discolored through a disorder known as red drupelet reversion (RDR). Over the past 50 years, breeding programs have achieved better fruit firmness and postharvest quality through traditional selection methods, but the underlying genetic variation is poorly understood.

Non-invasive detection of severe PH in lung disease using magnetic resonance imaging.

Introduction: Severe pulmonary hypertension (mean pulmonary artery pressure ≥35 mmHg) in chronic lung disease (PH-CLD) is associated with high mortality and morbidity. Data suggesting potential response to vasodilator therapy in patients with PH-CLD is emerging. The current diagnostic strategy utilises transthoracic Echocardiography (TTE), which can be technically challenging in some patients with advanced CLD.

Alberta Collaborative Quality Improvement Strategies to Improve Outcomes of Moderate and Late Preterm Infants (ABC-QI) Trial: a protocol for a multicentre, stepped-wedge cluster randomized trial.

Background: Evidence-based Practice for Improving Quality (EPIQ) is a collaborative quality improvement method adopted by the Canadian Neonatal Network that led to decreased mortality and morbidity in very preterm neonates. The Alberta Collaborative Quality Improvement Strategies to Improve Outcomes of Moderate and Late Preterm Infants (ABC-QI) Trial aims to evaluate the impact of EPIQ collaborative quality improvement strategies in moderate and late preterm neonates in Alberta, Canada.

Methods: In a 4-year, multicentre, stepped-wedge cluster randomized trial involving 12 neonatal intensive care units (NICUs), we will collect baseline data with the current practices in the first year (all NICUs in the control arm).

Brachial Artery Vasospasm From Sequential Use of Intravenous Promethazine and Dihydroergotamine for Treatment of Status Migrainosus: A Case Report.

Promethazine, a common antiemetic, can cause severe tissue injury with intravenous (IV) injection. Dihydroergotamine (DHE), commonly used for the acute treatment of migraine, can cause arterial vasoconstriction. We report a rare complication of brachial artery vasospasm in a patient receiving IV promethazine and DHE sequentially through the same midline IV catheter.

Contemporary cardiovascular computed tomography (CCT) training: Serial surveys of the international CCT community by the Fellow and Resident Leaders of the Society of Cardiovascular Computed Tomography (SCCT) Committee (FiRST) and SCCT Future Leaders Program (FLP).

Background: As cardiovascular computed tomography (CCT) practice evolves, the demand for specialists continues to increase. However, CCT training remains variable globally with limited contemporaneous data to understand this heterogeneity. We sought to understand the role of CCT globally and the training available to underpin its use.

Aspirin use is associated with improvement in distant metastases outcome in patients with residual disease after neoadjuvant chemotherapy.

Purpose: Aspirin (ASA) use has been correlated with improved outcomes in high-risk patients at risk for distant metastases. Breast cancer (BC) patients with residual disease, particularly nodal disease (ypN +) after neoadjuvant chemotherapy (NAC), are high-risk patients portending worse outcomes. We hypothesized that ASA use can reduce distant metastases and improve outcomes in these patients.
