Lifestyle changes are burdensome with my body broken by pain and obesity: patients' perspectives after pain rehabilitation.

Background: Despite the existing evidence regarding the interrelated relationship between pain and obesity, knowledge about patients' perspectives of this relationship is scarce, especially from patients with chronic pain and obesity after completing Interdisciplinary Pain Rehabilitation Program (IPRP).

Aims: This qualitative study expands the understanding of patients' perspectives on how chronic pain and obesity influence each other and how the two conditions affect the ability to make lifestyle changes.

Method: A purposive sample of patients with Body Mass Index (BMI) ≥ 30 kg/m and who had completed an IPRP were recruited for individual semi-structured interviews.

In-Hospital Mortality Following Traumatic Injury in South Africa.

Unlabelled: Trauma is a leading cause of death worldwide and in South Africa. We aimed to quantify the in-hospital trauma mortality rate in Pietermaritzburg, South Africa.

Background: The in-hospital trauma mortality rate in South Africa remains unknown, and it is unclear whether deficits in hospital care are contributing to the high level of trauma-related mortality.

Adrenergic nerves regulate intestinal regeneration through IL-22 signaling from type 3 innate lymphoid cells.

The intestinal epithelium has high intrinsic turnover rate, and the precise renewal of the epithelium is dependent on the microenvironment. The intestine is innervated by a dense network of peripheral nerves that controls various aspects of intestinal physiology. However, the role of neurons in regulating epithelial cell regeneration remains largely unknown.

Role of Underlying Liver Pathology in the Development of Immune-Related Hepatitis: A Case-Control Study.

Background: Immune-related hepatitis (irH) is a serious immune-related adverse event (IRAE) that may result in morbidity, immune checkpoint inhibitor (ICI) therapy interruption and, rarely, mortality. The impact of underlying liver pathology, including liver metastasis, on the incidence of irH remains poorly understood.

Objectives: We hypothesized that the presence of underlying liver pathology increased the risk of irH in patients with cancer treated with ICI.

Viral infection and allergy status impact severity of asthma symptoms in children with asthma exacerbations.

Background: Although viral infection is known to be associated with asthma exacerbations, prior research has not identified reliable predictors of acute symptom severity in virus-related asthma exacerbations (VRAEs).

Objective: To determine the effect of asthma control and viral infection on the severity of current illness and evaluate biomarkers related to acute symptoms during asthma exacerbations.

Methods: We prospectively enrolled 120 children with physician-diagnosed asthma and current wheezing who presented to Arkansas Children's Hospital emergency department.

The Spice of Death: Sudden Cardiac Arrest After Novel Psychoactive Substance Exposure.

Novel psychoactive substances (NPSs), commonly referred to as "K2" or "spice," are a relatively new toxicology challenge for pediatricians. Adolescents often incorrectly believe that these drugs are safe and can be used without major adverse effects. Although recent legislation attempts to ensure that these drugs are not commercially available, many are able to be purchased online as "not fit for human consumption" or under various misnomers such "incense.

Multispecialty Enterprise Imaging Workgroup Consensus on Interactive Multimedia Reporting Current State and Road to the Future: HIMSS-SIIM Collaborative White Paper.

Diagnostic and evidential static image, video clip, and sound multimedia are captured during routine clinical care in cardiology, dermatology, ophthalmology, pathology, physiatry, radiation oncology, radiology, endoscopic procedural specialties, and other medical disciplines. Providers typically describe the multimedia findings in contemporaneous electronic health record clinical notes or associate a textual interpretative report. Visual communication aids commonly used to connect, synthesize, and supplement multimedia and descriptive text outside medicine remain technically challenging to integrate into patient care.

IL-1R1-dependent signaling coordinates epithelial regeneration in response to intestinal damage.

Repair of the intestinal epithelium is tightly regulated to maintain homeostasis. The response after epithelial damage needs to be local and proportional to the insult. How different types of damage are coupled to repair remains incompletely understood.

Gremlin 1 fibroblastic niche maintains dendritic cell homeostasis in lymphoid tissues.

Fibroblastic reticular cells (FRCs) are specialized stromal cells that define tissue architecture and regulate lymphocyte compartmentalization, homeostasis, and innate and adaptive immunity in secondary lymphoid organs (SLOs). In the present study, we used single-cell RNA sequencing (scRNA-seq) of human and mouse lymph nodes (LNs) to identify a subset of T cell-zone FRCs defined by the expression of Gremlin1 (Grem1) in both species. Grem1-CreER knock-in mice enabled localization, multi-omics characterization and genetic depletion of Grem1 FRCs.

Distinct Mesenchymal Cell Populations Generate the Essential Intestinal BMP Signaling Gradient.

Intestinal stem cells (ISCs) are confined to crypt bottoms and their progeny differentiate near crypt-villus junctions. Wnt and bone morphogenic protein (BMP) gradients drive this polarity, and colorectal cancer fundamentally reflects disruption of this homeostatic signaling. However, sub-epithelial sources of crucial agonists and antagonists that organize this BMP gradient remain obscure.

Influence of penicillin treatment of horses with strangles on seropositivity to Streptococcus equi ssp. equi-specific antibodies.

Background: Antibiotic treatment of horses with strangles is reported to impair the development of immunity to subsequent exposure to Streptococcus equi ssp equi (S. equi). However, apart from a single clinical report, evidence-based studies for this hypothesis are lacking.

Nucleoporin insufficiency disrupts a pluripotent regulatory circuit in a pro-arrhythmogenic stem cell line.

Nucleoporins have been reported to regulate pluripotent biology, but how they do so remains partially characterized. This study examined the effects of nup155 gene disruption on mouse embryonic stem cells to gain insights into possible mechanisms by which nucleoporins regulate pluripotency in a pro-arrhythmogenic stem cell line. Embryonic stem cells with gene-trapped nup155 exhibited aberrant colony morphology underscored by abnormal transcriptome remodeling.

A New Dawn in Nationalism Studies? Some Fresh Incentives to Overcome Historiographical Nationalism.

Nationalism studies does not seem to be a very innovative field of research. The path-breaking views of Anderson, Gellner and Hobsbawm - all published in 1983 - still form the starting point for almost all existing investigations. Moreover, most recent studies focus on one national case, which implicitly results in a vast collection of 'unique' trajectories.

Emerging roles for nucleoporins in reproductive cellular physiology .

Nucleoporins are a specialized subset of nuclear proteins that comprise the nuclear pore complex and regulate nucleocytoplasmic transport. Recent demonstrations of roles for individual nucleoporins in multiple paradigms of differentiation via mechanisms independent of nuclear trafficking represent conceptual advances in understanding the contributions of nucleoporins to cellular development. Among these, a functional role for nucleoporins in reproductive fitness and gametogenesis has been identified, supported by robust models and clinical studies that leverage the power of next generation sequencing technology to identify reproductive-disease-associated mutations in specific nucleoporins.

NUP155 insufficiency recalibrates a pluripotent transcriptome with network remodeling of a cardiogenic signaling module.

Background: Atrial fibrillation is a cardiac disease driven by numerous idiopathic etiologies. NUP155 is a nuclear pore complex protein that has been identified as a clinical driver of atrial fibrillation, yet the precise mechanism is unknown. The present study employs a systems biology algorithm to identify effects of NUP155 disruption on cardiogenicity in a model of stem cell-derived differentiation.

Clinical outcome of Guillain-Barré syndrome after prolonged mechanical ventilation.

Background: Patients with Guillain-Barré syndrome (GBS) may suffer from respiratory failure for months or longer. The aim of this study was to determine the frequency, clinical course and outcome of patients with GBS requiring prolonged mechanical ventilation (MV).

Methods: Prospectively collected data from 526 patients with GBS participating in previous trials were analysed to determine the frequency and duration of prolonged MV (longer than 2 months).

Hemispheric Cerebral Oximetry Monitoring During Pediatric Seizure Activity in a Pediatric Emergency Department.

Background: Sustained neuronal activity during seizures causes cellular perturbations, alterations in cerebral physiology, and potentially neurological injury, a neurological emergency. With variable clinical manifestations of seizures, frequent failure of seizure recognition by providers in pediatric and developmentally challenged patients can increase seizure complications. Neuroresuscitation should include rapid cerebral physiology assessment for increased seizure recognition and optimal neurological outcomes.

Searching for Primordial Black Holes in the Radio and X-Ray Sky.

We model the accretion of gas onto a population of massive primordial black holes in the Milky Way and compare the predicted radio and x-ray emission with observational data. We show that, under conservative assumptions on the accretion process, the possibility that O(10)M_{⊙} primordial black holes can account for all of the dark matter in the Milky Way is excluded at 5σ by a comparison with a Very Large Array radio catalog at 1.4 GHz and at ≃40σ by a comparison with a Chandra x-ray catalog (0.

A distinct role for Lgr5 stem cells in primary and metastatic colon cancer.

Cancer stem cells (CSCs) have been hypothesized to represent the driving force behind tumour progression and metastasis, making them attractive cancer targets. However, conclusive experimental evidence for their functional relevance is still lacking for most malignancies. Here we show that the leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5) identifies intestinal CSCs in mouse tumours engineered to recapitulate the clinical progression of human colorectal cancer.

Dual display of proteins on the yeast cell surface simplifies quantification of binding interactions and enzymatic bioconjugation reactions.

Yeast surface display, a well-established technology for protein analysis and engineering, involves expressing a protein of interest as a genetic fusion to either the N- or C-terminus of the yeast Aga2p mating protein. Historically, yeast-displayed protein variants are flanked by peptide epitope tags that enable flow cytometric measurement of construct expression using fluorescent primary or secondary antibodies. Here, we built upon this technology to develop a new yeast display strategy that comprises fusion of two different proteins to Aga2p, one to the N-terminus and one to the C-terminus.

Hfq and three Hfq-dependent small regulatory RNAs-MgrR, RyhB and McaS-coregulate the locus of enterocyte effacement in enteropathogenic Escherichia coli.

Enteropathogenic Escherichia coli (EPEC) is a significant cause of infantile diarrhea and death in developing countries. The pathogenicity island locus of enterocyte effacement (LEE) is essential for EPEC to cause diarrhea. Besides EPEC, the LEE is also present in other gastrointestinal pathogens, most notably enterohemorrhagic E.
