Aortic dissection or rupture is a major cause of mortality in vascular Ehlers-Danlos Syndrome (vEDS), a connective tissue disorder caused by heterozygous mutations in the COL3A1 gene. C57BL6/J (BL6) mice carrying the Col3a1 G938D/+ mutation recapitulate the vEDS vascular phenotype and die suddenly of aortic rupture/dissection. However, 129S6/SvEvTac (129) mice expressing the same Col3a1 G938D/+ mutation show near-complete life-long protection from vascular rupture.

Causal Inference With Observational Data and Unobserved Confounding Variables.

Ecol Lett

January 2025

Department of Ecology and Evolutionary Biology, University of Colorado Boulder, Boulder, Colorado, USA.

Experiments have long been the gold standard for causal inference in Ecology. As Ecology tackles progressively larger problems, however, we are moving beyond the scales at which randomised controlled experiments are feasible. To answer causal questions at scale, we need to also use observational data -something Ecologists tend to view with great scepticism.

Importance: During buprenorphine treatment for opioid use disorder (OUD), risk factors for opioid relapse or treatment dropout include comorbid substance use disorder, anxiety, or residual opioid craving. There is a need for a well-powered trial to evaluate virtually delivered groups, including both mindfulness and evidence-based approaches, to address these comorbidities during buprenorphine treatment.

Objective: To compare the effects of the Mindful Recovery Opioid Use Disorder Care Continuum (M-ROCC) vs active control among adults receiving buprenorphine for OUD.

Pyrimidinergic P2Y1-Like Nucleotide Receptors Are Functional in Rat Conjunctival Goblet Cells.

Invest Ophthalmol Vis Sci

January 2025

Schepens Eye Research Institute, Massachusetts Eye and Ear Infirmary, Department of Ophthalmology, Harvard Medical School, Boston, Massachusetts, United States.

Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.

Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.

Comparative Effectiveness of Individual Sodium-Glucose Cotransporter 2 Inhibitors.

JAMA Intern Med

January 2025

Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts.

Importance: Evidence on cardiovascular benefits and safety of sodium-glucose cotransporter 2 (SGLT-2) inhibitors is mainly from placebo-controlled trials. Therefore, the comparative effectiveness and safety of individual SGLT-2 inhibitors remain unknown.

Objective: To compare the use of canagliflozin or dapagliflozin with empagliflozin for a composite outcome (myocardial infarction [MI] or stroke), heart failure hospitalization, MI, stroke, all-cause death, and safety outcomes, including diabetic ketoacidosis (DKA), lower-limb amputation, bone fracture, severe urinary tract infection (UTI), and genital infection and whether effects differed by dosage or cardiovascular disease (CVD) history.

Background: The role of activating alterations in the MAPK pathway in predicting immunotherapy efficacy in lung squamous cell carcinoma (LSCC) patients is largely unknown. The aims of the randomized, phase II SQUINT trial were to assess the efficacy of nivolumab plus ipilimumab (NI) versus platinum-based chemotherapy plus nivolumab (N-CT) and to identify clinically available biomarkers of response to immunotherapy in patients with advanced or metastatic LSCC.

Methods: SQUINT was an open-label, randomized, parallel, non-comparative, phase II trial of NI versus N-CT in chemo-naïve, metastatic or recurrent LSCC adult patients.

Background: Anterior cruciate ligament (ACL) tears are frequent injuries in athletes that often require surgical reconstruction so that patients may return to their previous levels of performance. While existing data on patient-reported outcomes are similar between bone-patellar tendon-bone (BTB) and hamstring tendon (HT) autografts, the literature regarding return to sport (RTS), return to previous levels of sport activity, and graft failure rate remains limited.

Purpose: To compare rates of RTS, return to previous activity levels, and graft retears among athletes undergoing primary ACL reconstruction using a BTB versus HT autograft.

Percutaneous coronary interventions in highly calcified atherosclerotic lesions are challenging due to the high mechanical stiffness that significantly restricts stent expansion. Intravascular lithotripsy (IVL) is a novel vessel preparation technique with the potential to improve interventional outcomes by inducing microscopic and macroscopic cracks to enhance stent expansion. However, the exact mechanism of action for IVL is poorly understood, and it remains unclear whether the improvement in-stent expansion is caused by either the macro-cracks allowing the vessel to open or the micro-cracks altering the bulk material properties.

Liver masses are common in children, however primary malignant neoplasms are rare, representing only 1% of all pediatric cancers. Hepatocellular neoplasms are the most common primary liver malignancies and hepatoblastoma (HB) is the most frequently diagnosed. The incidence of HB, which is increasing, is approximately of 2 cases per million in the United States, followed by hepatocellular carcinoma (HCC).

Cardiovascular imaging in children with cardiac implantable electronic devices.

Pediatr Radiol

January 2025

Department of Cardiology, Boston Children's Hospital and Department of Pediatrics, Harvard Medical School, Boston, MA, 02115, USA.

The number of children with cardiac implantable electronic devices (CIEDs) is increasing at a time of rapid growth in cardiac magnetic resonance (MR) and cardiac computed tomography (CT) utilization. The presence of CIEDs poses challenges with respect to imaging safety and quality. A thoughtful approach to cardiovascular imaging in patients with CIEDs begins with an awareness of the clinical indications to determine the most appropriate imaging modality.

Introduction: Positionality statements accompanying peer-reviewed publications are increasingly being implemented in academic journals across many disciplines, including psychology. These statements serve as transparent, public acknowledgments of the authors' identities, which can offer valuable insight into the authors' work in the context of their lived experiences and potential biases. However, journal editors and associated staff risk harm by uniformly adopting a policy on positionality statements without consideration of the unintended consequences of implementing such practices.

Asthma is a genetically complex inflammatory airway disease associated with over 200 Single nucleotide polymorphisms (SNPs). However, the functional effects of many asthma-associated SNPs in lung and airway epithelial samples are unknown. Here, we aimed to conduct expression quantitative trait loci (eQTL) analysis using a meta-analysis of nasal and lung samples.

The plastisphere, defined as the ecological niche for microbial colonization of plastic debris, has been recognized as a hotspot of pathogenic and antibiotic-resistant bacteria. However, the interactions between bacteria and phages facilitated by the plastisphere, as well as their impact on microbial risks to public health, remain unclear. Here, we analyzed public metagenomic data from 180 plastisphere and environmental samples, stemming from four different habitats and two plastic types (biodegradable and nonbiodegradable plastics) and obtained 611 nonredundant metagenome-assembled genomes (MAGs) and 4061 nonredundant phage contigs.

Staging of pediatric Hodgkin lymphoma is currently based on the Ann Arbor classification, incorporating the Cotswold modifications and the Lugano classification. The Cotswold modifications provide guidelines for the use of CT and MRI. The Lugano classification emphasizes the importance of CT and PET/CT in evaluating both Hodgkin lymphoma and non-Hodgkin lymphoma but focuses on adult patients.
