Human pluripotent stem cells (hPSCs) have been reported in naive and primed states. However, the ability to generate mature cell types remains the imperative property for utility of hPSCs. Here, we reveal that the naive state enhances self-renewal while restricting lineage differentiation in vitro to neural default fate. Molecular analyses indicate expression of multiple lineage-associated transcripts in naive hPSCs that failed to predict biased functional differentiation capacity. Naive hPSCs can be converted to primed state over long-term serial passage that permits recovery of multi-germ layer differentiation...

OBJECTIVE: While tocilizumab (TCZ) is known to increase LDL cholesterol, it is unclear whether TCZ increases cardiovascular (CV) risks in patients with rheumatoid arthritis (RA). METHODS: To examine comparative CV safety, we conducted a cohort study of RA patients who newly started TCZ or TNFi using claims data from Medicare, IMS PharMetrics and MarketScan. All patients were required to have previously used a different TNFi, abatacept, or tofacitinib. The primary outcome was a composite CV endpoint of hospitalization for myocardial infarction (MI) or stroke...

BACKGROUND: Neuroblastoma (NB), a tumor of the primitive neural crest, despite aggressive treatment portends a poor long-term survival for patients with advanced high stage NB. New treatment strategies are required. METHODS: We investigated coordinated targeting of essential homeostatic regulatory factors involved in cancer progression, histone deacetylases (HDACs) and carbonic anhydrases (CAs). RESULTS: We evaluated the antitumor potential of the HDAC inhibitor (HDACi), pyridylmethyl-N-{4-[(2-aminophenyl)-carbamoyl]-benzyl}-carbamate (MS-275) in combination with a pan CA inhibitor, acetazolamide (AZ) on NB SH-SY5Y, SK-N-SH and SK-N-BE(2) cells...

In this study, we report the gut microbial composition and predictive functional profiles of zebrafish, Danio rerio, fed with a control formulated diet (CFD), and a gluten formulated diet (GFD) using a metagenomics approach and bioinformatics tools. The microbial communities of the GFD-fed D. rerio displayed heightened abundances of Legionellales, Rhizobiaceae, and Rhodobacter, as compared to the CFD-fed counterparts. Predicted metagenomics of microbial communities (PICRUSt) in GFD-fed D. rerio showed KEGG functional categories corresponding to bile secretion, secondary bile acid biosynthesis, and the metabolism of glycine, serine, and threonine...

OBJECTIVE: Giant cell arteritis (GCA) is an inflammatory vasculitis preferentially affecting large and medium-sized arteries. High-dose oral glucocorticoids (GCs) are the mainstay of GCA therapy. Using data from the UK Clinical Practice Research Datalink (CPRD), we examined the risk of oral GC-related serious adverse events (SAEs) in a UK population of patients with giant cell arteritis (GCA). METHODS: We conducted a series of nested case-control analyses in GCA patients to examine the effect of increasing dose of prednisolone on the risk of developing diabetes, glaucoma, osteoporosis, fractures, serious infection requiring hospitalization, and death...

Ticks are important vectors of emerging and re-emerging zoonoses, the majority of which originate from wildlife. In recent times, this has become a global public health concern that necessitates surveillance of both known and unknown tick-borne pathogens likely to be future disease threats, as well as their tick vectors. We carried out a survey of the diversity of ticks and tick-borne pathogens in Kenya's Shimba Hills National Reserve (SHNR), an area with intensified human-livestock-wildlife interactions, where we collected 4297 questing ticks (209 adult ticks, 586 nymphs and 3502 larvae)...

Dysregulation of the type I interferon (IFN) system is associated with various immunologic diseases, such as systemic lupus erythematosus (SLE). Targeting this dysregulation presents an attractive approach for SLE therapy. Sifalimumab, a fully human immunoglobulin G1 κ monoclonal antibody that binds to and neutralizes most IFN-α subtypes, has been recently evaluated in a Phase IIb study in patients with moderate to severe SLE. Insights gained from earlier studies were used to inform design of the Phase IIb study, to provide a more comprehensive evaluation of sifalimumab...

Chronic Lymphocytic Leukaemia (CLL) is a monoclonal lymphoid malignancy characterized by progressive accumulation of small, mature but functionally incompetent neoplastic lymphocytes in the peripheral blood, bone marrow and lymphoid organs. Patients present a variable course and may not require early intervention unlike other malignancies. Patients with rapidly deteriorating blood counts, and organomegaly need treatment. Alkylating agent live Bendamustine combined with Rituximab, anti-CD 20 monoclonal antibody have shown promising results in such patients...

Thoracic endovascular aortic repair (TEVAR) offers a less invasive treatment for aortic arch aneurysms. Clinical challenges arise when there is inadequate proximal landing for zone 1 TEVAR, such that a median sternotomy with total aortic debranching is required before stent deployment. The chimney technique was reported as an alternative approach to stent the arch branches and avoid sternotomy, but it was still associated with considerable chance of a type IA endoleak. We report a case of aortic arch aneurysm with an inadequate proximal landing for zone 1 TEVAR that was treated with debranching of head and neck vessels followed by TEVAR and preemptive and targeted coil embolization of the arch aneurysmal sac...

Young adults have low rates of outpatient service utilization and higher rates of emergency service use compared to older adults. This study explored pathways to crisis service use for uninsured young adults who accessed emergency psychiatric treatment. Participants were 55 young adults (ages 18-25) who were on an inpatient short-term stabilization unit and had qualifying diagnoses for outpatient services (bipolar, major depression, or schizophrenia). Semistructured qualitative interviews were conducted to understand decision-making and the events that led to service use...

Invasive species may impact pathogen transmission by altering the distributions and interactions among native vertebrate reservoir hosts and arthropod vectors. Here, we examined the direct and indirect effects of the red imported fire ant (Solenopsis invicta) on the native tick, small mammal and pathogen community in southeast Texas. Using a replicated large-scale field manipulation study, we show that small mammals were more abundant on treatment plots where S. invicta populations were experimentally reduced...

An elderly man presented with fever and evidence of Salmonella infection, and was diagnosed to have coexisting constrictive pericarditis and mycotic aneurysm of the aortic arch. Pericardiectomy was performed under cardiopulmonary bypass with good result. To avoid deep hypothermic circulatory arrest, an aorto-brachiocephalic bypass, instead of total arch replacement, was performed. This was followed by a staged carotid-carotid bypass, thoracic endovascular stent graft placement. He was subsequently treated with prolonged antibiotics, and inflammatory marker normalized afterwards...
