Isolated and Combined Effects of Moderate Normobaric Hypoxia and Sleep Restriction on Energy Intake and Food Reward.

Hypoxia (HY) and sleep deprivation have opposite effects on appetite. As HY may alter sleep, it may be informative to assess the accumulative effects of these two stressors on hunger, energy intake (EI), and food reward. Seventeen young, active, healthy males completed four 5-hr sessions in normoxia (NO) or normobaric HY (FIO2 = 13.

A National Dental Practice-Based Research Network phase II, cluster-randomized clinical trial assessing nicotine replacement therapy sampling in dental settings: study protocol for the Free Samples for Health (FreSH) study.

Background: Cigarette smoking has major detrimental effects on oral health. Tobacco interventions in dental settings are effective, but rarely delivered. The American Dental Hygienists Association recommends that oral health providers: Ask patients about tobacco use, Advise quitting tobacco use, and Refer to state quitlines (Ask-Advise-Refer; AAR).

NAB2::STAT6 fusions and genome-wide DNA methylation profiling: Predictors of patient outcomes in meningeal solitary fibrous tumors.

Meningeal solitary fibrous tumors (SFT) are rare and have a high frequency of local recurrence and distant metastasis. In a cohort of 126 patients (57 female, 69 male; mean age at surgery 53.0 years) with pathologically confirmed meningeal SFTs with extended clinical follow-up (median 9.

Transcatheter Edge-to-Edge Repair for Acute Papillary Muscle Rupture After Transvenous Lead Extraction in a d-TGA.

We present a case of a patient known for dextrotransposition of the great arteries corrected with a Mustard procedure, in whom severe mitral valve regurgitation secondary to transvenous lead extraction was successfully repaired with transcatheter edge-to-edge repair using the TriClip device (Abbott Vascular).

Left Anterior Descending Coronary Artery Mimic: A Case of Coronary Artery to Pulmonary Artery Fistula.

Coronary artery fistulas (CAFs) are rare coronary anomalies involving the communication of an epicardial coronary artery and another cardiovascular structure. CAFs are usually easily distinguished from nearby coronary arteries. Here, we report a unique case of CAF that mimics the size, branching pattern, and appearance of a native epicardial left anterior descending artery.

The Cardiovascular Manifestations of COVID-19.

The Coronavirus 2019 (COVID-19) pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus, has resulted in unprecedented morbidity and mortality worldwide. While COVID-19 typically presents as viral pneumonia, cardiovascular manifestations such as acute coronary syndromes, arterial and venous thrombosis, acutely decompensated heart failure (HF), and arrhythmia are frequently observed. Many of these complications are associated with poorer outcomes, including death.

Atretic cephalocele and encephalocele: A single-institution clinicopathological study.

Background: Encephaloceles are neural tube defects characterized by herniation of meninges, neural tissue and cerebrospinal fluid, while atretic cephaloceles denote a rudimentary connection to the intracranial space with absence of herniated neural tissue and represent an infrequent dermatopathologic diagnosis. Limited reports of these entities confound the challenge in their histopathologic distinction. Accurate classification is important given associated anomalies and neurologic manifestations that impact prognosis.

Preadmission Oral Anticoagulation for Atrial Fibrillation/Flutter and Death or Thrombotic Events During COVID-19 Admission.

Atrial fibrillation/flutter (AF) and COVID-19 are associated with an elevated risk of arterial and venous thrombosis. Whether preadmission oral anticoagulation (OAC) for AF reduces the incidence of in-hospital death or thrombotic events among patients with COVID-19 is unknown. We identified 630 patients with pre-existing AF and a hospitalization diagnosis of COVID-19 and stratified them according to preadmission OAC use.

The Cardiovascular Manifestations of COVID-19.

The Coronavirus 2019 (COVID-19) pandemic, caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus, has resulted in unprecedented morbidity and mortality worldwide. While COVID-19 typically presents as viral pneumonia, cardiovascular manifestations such as acute coronary syndromes, arterial and venous thrombosis, acutely decompensated heart failure (HF), and arrhythmia are frequently observed. Many of these complications are associated with poorer outcomes, including death.

Preadmission Statin Treatment and Outcome in Patients Hospitalized With COVID-19.

Preadmission statin therapy is associated with improved outcome in patients hospitalized with COVID-19. Whether inhibition of inflammation and myocardial injury are in part responsible for this observation has not been studied. The aim of the present study was to relate preadmission statin usage to markers of inflammation, myocardial injury, and clinical outcome among patients with established atherosclerosis who were admitted with COVID-19.

Association Between COVID-19 Diagnosis and In-Hospital Mortality in Patients Hospitalized With ST-Segment Elevation Myocardial Infarction.

Importance: There has been limited research on patients with ST-segment elevation myocardial infarction (STEMI) and COVID-19.

Objective: To compare characteristics, treatment, and outcomes of patients with STEMI with vs without COVID-19 infection.

Design, Setting, And Participants: Retrospective cohort study of consecutive adult patients admitted between January 2019 and December 2020 (end of follow-up in January 2021) with out-of-hospital or in-hospital STEMI at 509 US centers in the Vizient Clinical Database (N = 80 449).

Alloantigen-specific type 1 regulatory T cells suppress through CTLA-4 and PD-1 pathways and persist long-term in patients.

Type 1 regulatory T (Tr1) cells are inducible, interleukin (IL)-10FOXP3 regulatory T cells that can suppress graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We have optimized an in vitro protocol to generate a Tr1-enriched cell product called T-allo10, which is undergoing clinical evaluation in patients with hematological malignancies receiving a human leukocyte antigen (HLA)–mismatched allo-HSCT. Donor-derived T-allo10 cells are specific for host alloantigens, are anergic, and mediate alloantigen-specific suppression.

Cardiovascular magnetic resonance findings in young adult patients with acute myocarditis following mRNA COVID-19 vaccination: a case series.

Background: Messenger RNA (mRNA) coronavirus disease of 2019 (COVID-19) vaccine are known to cause minor side effects at the injection site and mild global systemic symptoms in first 24-48 h. Recently published case series have reported a possible association between acute myocarditis and COVID-19 vaccination, predominantly in young males.

Methods: We report a case series of 5 young male patients with cardiovascular magnetic resonance (CMR)-confirmed acute myocarditis within 72 h after receiving a dose of an mRNA-based COVID-19 vaccine.

Multimodal Imaging for the Diagnosis of Isolated Cardiac Sarcoidosis.

We report a case of isolated cardiac sarcoidosis (CS) diagnosed using a multimodality imaging approach. A patient presented after an out-of-hospital, ventricular fibrillation-mediated cardiac arrest. The use of echocardiography, cardiac magnetic resonance, and fluorodeoxyglucose-positron emission tomography enabled the diagnosis of isolated CS.

The 2021 WHO Classification of Tumors of the Central Nervous System: a summary.

The fifth edition of the WHO Classification of Tumors of the Central Nervous System (CNS), published in 2021, is the sixth version of the international standard for the classification of brain and spinal cord tumors. Building on the 2016 updated fourth edition and the work of the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy, the 2021 fifth edition introduces major changes that advance the role of molecular diagnostics in CNS tumor classification. At the same time, it remains wedded to other established approaches to tumor diagnosis such as histology and immunohistochemistry.
