Content analysis of perceptions of combined pharmacobehavioral treatment for American Indian people with opioid use disorder.

Objective: Both opioid misuse and overdose mortality have disproportionately impacted the American Indian population. Although medications for opioid use disorder, such as buprenorphine (BUP-NX), are highly effective in reducing overdose mortality, questions have been raised about the cultural acceptability of Western medical approaches in this population. Understanding patients' desired recovery pathways can lead to more culturally appropriate, patient-centered, and effective approaches to opioid use disorder (OUD) treatment.

Stem-cell states converge in multistage cutaneous squamous cell carcinoma development.

Stem cells play a critical role in cancer development by contributing to cell heterogeneity, lineage plasticity, and drug resistance. We created gene expression networks from hundreds of mouse tissue samples (both normal and tumor) and integrated these with lineage tracing and single-cell RNA-seq, to identify convergence of cell states in premalignant tumor cells expressing markers of lineage plasticity and drug resistance. Two of these cell states representing multilineage plasticity or proliferation were inversely correlated, suggesting a mutually exclusive relationship.

Crowdsourcing temporal transcriptomic coronavirus host infection data: Resources, guide, and novel insights.

The emergence of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) reawakened the need to rapidly understand the molecular etiologies, pandemic potential, and prospective treatments of infectious agents. The lack of existing data on SARS-CoV-2 hampered early attempts to treat severe forms of coronavirus disease-2019 (COVID-19) during the pandemic. This study coupled existing transcriptomic data from severe acute respiratory syndrome-related coronavirus 1 (SARS-CoV-1) lung infection animal studies with crowdsourcing statistical approaches to derive temporal meta-signatures of host responses during early viral accumulation and subsequent clearance stages.

Combination Dabrafenib and Trametinib Versus Combination Nivolumab and Ipilimumab for Patients With Advanced -Mutant Melanoma: The DREAMseq Trial-ECOG-ACRIN EA6134.

Purpose: Combination programmed cell death protein 1/cytotoxic T-cell lymphocyte-4-blockade and dual BRAF/MEK inhibition have each shown significant clinical benefit in patients with -mutant metastatic melanoma, leading to broad regulatory approval. Little prospective data exist to guide the choice of either initial therapy or treatment sequence in this population. This study was conducted to determine which initial treatment or treatment sequence produced the best efficacy.

Risk Factors Associated With Postoperative Mortality Among COVID-19 Positive Patients: Results of 3027 Operations and Procedures.

Objective: To investigate the predictors of postoperative mortality in coronavirus disease 2019 (COVID-19)-positive patients.

Background: COVID-19-positive patients have more postoperative complications. Studies investigating the risk factors for postoperative mortality in COVID-19-positive patients are limited.

Defining Patient-Level Molecular Heterogeneity in Psoriasis Vulgaris Based on Single-Cell Transcriptomics.

Identifying genetic variation underlying human diseases establishes targets for therapeutic development and helps tailor treatments to individual patients. Large-scale transcriptomic profiling has extended the study of such molecular heterogeneity between patients to somatic tissues. However, the lower resolution of bulk RNA profiling, especially in a complex, composite tissue such as the skin, has limited its success.

The first international Delphi consensus statement on Laparoscopic Gastrointestinal surgery.

Background: Laparoscopic surgery has almost replaced open surgery in many areas of Gastro-Intestinal (GI) surgery. There is currently no published expert consensus statement on the principles of laparoscopic GI surgery. This may have affected the training of new surgeons.

Adaptive significance of flowering time variation across natural seasonal environments in Arabidopsis thaliana.

The relevance of flowering time variation and plasticity to climate adaptation requires a comprehensive empirical assessment. We investigated natural selection and the genetic architecture of flowering time in Arabidopsis through field experiments in Europe across multiple sites and seasons. We estimated selection for flowering time, plasticity and canalization.

Untargeted Metabolomics Analysis of the Serum Metabolic Signature of Childhood Obesity.

Obesity rates among children are growing rapidly worldwide, placing massive pressure on healthcare systems. Untargeted metabolomics can expand our understanding of the pathogenesis of obesity and elucidate mechanisms related to its symptoms. However, the metabolic signatures of obesity in children have not been thoroughly investigated.

Interest in Improving Access to Pediatric Trauma Care Through Telemedicine.

Despite improved outcomes at pediatric trauma centers (PTC), 90% of injured children are not treated at PTCs. Telemedicine may play a role in ensuring patients are transferred to the appropriate level of care. We aimed to determine the level of interest in trauma telemedicine with our PTC among referring facilities.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database: 2021 Update on Echocardiography.

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) is the world's premier clinical outcomes registry for adult cardiac surgery and a driving force for quality improvement in cardiac surgery. Echocardiographic data provide a wealth of hemodynamic, structural, and functional data and have been part of STS ACSD data collection since its inception. An increasing body of evidence suggests that the use of echocardiography in patients undergoing cardiac surgery has a positive impact on postoperative outcomes.

Combining conventional QTL analysis and whole-exome capture-based bulk-segregant analysis provides new genetic insights into tuber sprout elongation and dormancy release in a diploid potato population.

Tuber dormancy and sprouting are commercially important potato traits as long-term tuber storage is necessary to ensure year-round availability. Premature dormancy release and sprout growth in tubers during storage can result in a significant deterioration in product quality. In addition, the main chemical sprout suppressant chlorpropham has been withdrawn in Europe, necessitating alternative approaches for controlling sprouting.

Combining sonodynamic therapy with chemoradiation for the treatment of pancreatic cancer.

Treatment options for patients with pancreatic cancer are limited and survival prospects have barely changed over the past 4 decades. Chemoradiation treatment (CRT) has been used as neoadjuvant therapy in patients with borderline resectable disease to reduce tumour burden and increase the proportion of patients eligible for surgery. Antimetabolite drugs such as gemcitabine and 5-fluorouracil are known to sensitise pancreatic tumours to radiation treatment.

Perioperative and long-term functional outcomes of neonatal versus delayed primary endorectal pull-through for children with Hirschsprung disease: A pediatric colorectal and pelvic learning consortium study.

Background/purpose: the timing of endorectal pull-through for Hirschsprung disease (HD) is controversial. Neonatal primary endorectal pull-through theoretically prevents preoperative enterocolitis. Delayed primary endorectal pull-through offers the surgeon the benefit of more robust perineal anatomy and allows primary caregivers the time to emotionally process the diagnosis and to gain experience with rectal irrigations.

Dexmedetomidine, Delirium, and Adverse Outcomes: Analysis of the Society of Thoracic Surgeons Adult Cardiac Surgery Database.

Background: We tested the hypothesis that dexmedetomidine was associated with a reduced incidence of postoperative delirium (POD) and adverse outcomes in cardiac surgery patients from The Society of Thoracic Surgeons Adult Cardiac Surgery Database including the Adult Cardiac Anesthesiology subsection.

Methods: We identified 55,905 patients in The Society of Thoracic Surgeons Adult Cardiac Surgery Database who underwent cardiac surgery between July 2014 and December 2018. Using propensity score-weighted regression analysis, we analyzed the effect of intraoperative dexmedetomidine on the primary (POD) and secondary outcomes (highest pain score on day 3 and at discharge, stroke, prolonged ventilation, postoperative intubation/reintubation, additional postoperative hours ventilated, renal failure, atrial fibrillation, and 30-day mortality).

Immune cell infiltrates as prognostic biomarkers in pancreatic ductal adenocarcinoma: a systematic review and meta-analysis.

Immune cell infiltration has been identified as a prognostic biomarker in several cancers. However, no immune based biomarker has yet been validated for use in pancreatic ductal adenocarcinoma (PDAC). We undertook a systematic review and meta-analysis of immune cell infiltration, measured by immunohistochemistry (IHC), as a prognostic biomarker in PDAC.

Pulmonary Manifestations of Inflammatory Bowel Disease in Children.

The recognition of pulmonary manifestations of inflammatory bowel disease (IBD) is important as these diseases can be confused with infectious etiologies (e.g., tuberculosis or fungal infection) and, as a result, may unnecessarily delay institution of appropriate therapy (e.
