Article Synopsis
  • - Purulent pericarditis is a serious infection of the pericardial space, exemplified by a case of a 41-year-old man who developed this condition alongside a pulmonary infection, likely triggered by histoplasmosis complicating his health.
  • - The patient experienced cardiac tamponade, requiring immediate drainage, and had complicated symptoms leading to a diagnosis of pericardial constriction confirmed by cardiac MRI, indicating inflammation and abnormal heart function.
  • - Treatment involved antibiotics and antifungal medications, emphasizing the need for a comprehensive evaluation of underlying infections, the need for emergency interventions, and the roles of echocardiography and possible surgery (pericardiectomy) in managing severe cases.

Introduction: Mental health symptoms such as depression, anxiety and sleep problems are commonly observed in individuals suffering from acute COVID-19 infection to post-COVID-19 syndrome. Studies have provided preliminary evidence for the efficacies of cognitive behavioural therapy, mindfulness-based interventions, acceptance and commitment therapy, and many other treatments for this population. Although there have been attempts to synthesise the literature on these psychological interventions, previous reviews have been limited in terms of the sources, symptoms and interventions that they included.

Perforin is a key effector of lymphocyte-mediated cell death pathways and contributes to transplant rejection of immunologically mismatched grafts. We have developed a novel series of benzenesulfonamide (BZS) inhibitors of perforin that can mitigate graft rejection during allogeneic bone marrow/stem cell transplantation. Eight such perforin inhibitors were tested for their murine pharmacokinetics, plasma protein binding, and their ability to block perforin-mediated lysis and to block the rejection of major histocompatibility complex (MHC)-mismatched mouse bone marrow cells.

Older horses and those prone to obesity may be at a higher risk for inflammation than younger and leaner counterparts. Previous research indicated a postprandial elevation in plasma concentrations of interleukin-1β (IL-1β), a pro-inflammatory cytokine, after consuming 1.2 g of non-structural carbohydrates/kilogram of body weight.

Objectives: Out-of-hospital cardiac arrest (OHCA) is associated with excessively high mortality rates. Recent studies suggest benefits from extracorporeal cardiopulmonary resuscitation (ECPR) performed in selected patients. We sought to present the first results from our interdisciplinary ECPR program with a particular focus on early outcomes and potential risk factors associated with in-hospital mortality.

Background: Transsternal open thymectomy has long been the most widely used approach for thymectomy, but recent decades have seen the introduction of minimally invasive surgery (MIS), such as video-assisted thoracoscopic surgery (VATS) and robot-assisted thoracoscopic surgery (RATS) thymectomy. This retrospective cohort study provides a national comparison of trends, outcomes, and resource utilization of open, VATS, and RATS thymectomy.

Methods: Admissions for thymectomies from 2008 to 2014 were identified in the National Inpatient Sample.

Penile fracture (PF) is a surgical emergency. Given its rarity, we queried a national cohort over an 11-year period to study the temporal and demographic variations in presentation, evaluation, and management of patients with PF compared with a cohort of control patients. The National Inpatient Sample was queried between the years 2005 and 2016 for patients with a diagnosis of PF.

Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for portal hypertensive complications, but its effect on renal function is not well characterized. Here we describe renal function and characteristics associated with renal dysfunction at 30 days post-TIPS. Adults with cirrhosis who underwent TIPS at 9 hospitals in the United States from 2010 to 2015 were included.

Variant allele frequencies (VAF) are an important measure of genetic variation that can be estimated at single-nucleotide variant (SNV) sites. RNA and DNA VAFs are used as indicators of a wide-range of biological traits, including tumor purity and ploidy changes, allele-specific expression and gene-dosage transcriptional response. Here we present a novel methodology to assess gene and chromosomal allele asymmetries and to aid in identifying genomic alterations in RNA and DNA datasets.

Malnutrition is associated with increased mortality in open cardiac surgery, but its impact on transcatheter aortic valve implantation (TAVI) is unknown. This study utilized the National Readmissions Database to evaluate the impact of malnutrition on mortality, complications, length of stay (LOS), 30-day readmission, and total charges following TAVI. Adult patients undergoing isolated TAVI for severe aortic stenosis were identified using the 2011 to 2016 National Readmissions Database, which accounts for 56.

Perforin is a key effector protein in the vertebrate immune system and is secreted by cytotoxic T lymphocytes and natural killer cells to help eliminate virus-infected and transformed target cells. The ability to modulate perforin activity in vivo could be extremely useful, especially in the context of bone marrow stem cell transplantation where early rejection of immunologically mismatched grafts is driven by the recipient's natural killer cells, which overwhelmingly use perforin to kill their targets. Bone marrow stem cell transplantation is a potentially curative treatment for both malignant and nonmalignant disorders, but when the body recognizes the graft as foreign, it is rejected by this process, often with fatal consequences.

Protein phosphatase 1 isoforms α, β, and γ (PP1α, PP1β, and PP1γ) are highly homologous in the catalytic domains but have distinct subcellular localizations. In this study, we utilized both primary cell culture and knockout mice to investigate the isoform-specific roles of PP1s in the heart. In both neonatal and adult cardiac myocytes, PP1β was mainly localized in the nucleus, compared to the predominant presence of PP1α and PP1γ in the cytoplasm.

Hepatocellular carcinoma (HCC) remains the most common primary liver malignancy. Pain comprises one of the most pervasive and troubling symptoms of HCC and may have severely negative effects on patient's quality of life. Furthermore, because HCC frequently arises in the setting of cirrhosis, treating pain related to this malignancy poses a clinical challenge.

Article Synopsis
  • - BM-MSCs have shown promise in treating CNS demyelinating diseases like multiple sclerosis (MS), but clinical trials reveal mixed results, possibly due to the source of the cells.
  • - A study comparing gene expression in BM-MSCs from EAE (a model of MS) and healthy animals found significant changes in gene expression, particularly in pathways linked to inflammation and neural development.
  • - The findings suggest that EAE-derived BM-MSCs may inhibit remyelination instead of promoting it, indicating the potential need for using non-autologous MSCs in future MS clinical trials.

Asymmetric allele content in the transcriptome can be indicative of functional and selective features of the underlying genetic variants. Yet, imbalanced alleles, especially from diploid genome regions, are poorly explored in cancer. Here we systematically quantify and integrate the variant allele fraction from corresponding RNA and DNA sequence data from patients with breast cancer acquired through The Cancer Genome Atlas (TCGA).

The structure-activity relationships for a series of arylsulphonamide-based inhibitors of the pore-forming protein perforin have been explored. Perforin is a key component of the human immune response, however inappropriate activity has also been implicated in certain auto-immune and therapy-induced conditions such as allograft rejection and graft versus host disease. Since perforin is expressed exclusively by cells of the immune system, inhibition of this protein would be a highly selective strategy for the immunosuppressive treatment of these disorders.

The pore-forming protein perforin is a key component of mammalian cell-mediated immunity and essential to the pathway that allows elimination of virus-infected and transformed cells. Perforin activity has also been implicated in certain auto-immune conditions and therapy-induced conditions such as allograft rejection and graft versus host disease. An inhibitor of perforin activity could be used as a highly specific immunosuppressive treatment for these conditions, with reduced side-effects compared to currently accepted therapies.

A Pd-catalysed amination method is used to convert seco-CBI, a synthetic analogue of the alkylating subunit of the duocarmycin natural products, from the phenol to amino form. This allows efficient enantioselective access to the more potent S enantiomer of aminoCBI and its incorporation into analogues of DNA minor groove cross-linking agents. Evaluation in a panel of nine human tumour cell lines shows that the bifunctional agents containing aminoCBI are generally less cytotoxic than their phenolCBI analogues and more susceptible to P-glycoprotein-mediated resistance.

In Leo Tolstoy's famous novella, The Death of Ivan Ilyich, a rich and meaningful inner life is sacrificed in pursuit of material rewards and social status. How can we cultivate something intrinsic that transcends our worldly accomplishments? Assuming that a basic model or map of human nature is needed to navigate the road to the good life, what desires, tendencies, and aversions constitute our core nature? How has our evolutionary history shaped our moral impulses? Are we inherently good or fundamentally flawed? Steve Paulson, executive producer and host of To the Best of Our Knowledge, moderated a discussion with philosopher Christian Miller, neuroscientist Heather Berlin, and historian of science Michael Shermer to examine our moral ecology and its influence on our underlying assumptions about human nature.
