RATIONALE: Interstitial lung disease (ILD) is an important cause of morbidity and mortality in scleroderma (Scl). Risk prediction and prognostication in Scl-ILD patients is challenging because of heterogeneity in the disease course. METHODS: We aimed to develop a clinical mortality risk prediction model for Scl-ILD. Patients with Scl-ILD were identified from two ongoing longitudinal cohorts: 135 patients at the University of California, San Francisco (UCSF, derivation cohort) and 90 patients at the Mayo Clinic (validation cohort)...

OBJECTIVE: To discern recurrence risk stratification and investigate its influence on postoperative surveillance in patients with esophageal adenocarcinoma (EAC) after neoadjuvant chemoradiotherapy (CRT). BACKGROUND: Reports documenting recurrence risk stratification in EAC after neoadjuvant CRT are scarce. METHODS: Between 1998 and 2014, 601 patients with EAC who underwent neoadjuvant CRT followed by esophagectomy were included for analysis...

In our continued effort to discover and develop best-in-class Bruton's tyrosine kinase (Btk) inhibitors for the treatment of B-cell lymphomas, rheumatoid arthritis, and systemic lupus erythematosus, we devised a series of novel tricyclic compounds that improved upon the druglike properties of our previous chemical matter. Compounds exemplified by G-744 are highly potent, selective for Btk, metabolically stable, well tolerated, and efficacious in an animal model of arthritis.

Improving access to the carbohydrate content of lignocellulose is key to reducing recalcitrance for microbial deconstruction and conversion to fuels and chemicals. Caldicellulosiruptor bescii completely solubilizes naked microcrystalline cellulose, yet this transformation is impeded within the context of the plant cell wall by a network of lignin and hemicellulose. Here, the bioavailability of carbohydrates to C. bescii at 70°C was examined for reduced lignin transgenic switchgrass lines COMT3(+) and MYB Trans, their corresponding parental lines (cultivar Alamo) COMT3(-) and MYB WT, and natural variant cultivar Cave-in-Rock (CR)...

Three MOF-74-type Co(II) frameworks with one-dimensional hexagonal channels have been prepared. Co(II) spins in a chain are ferromagnetically coupled through carboxylate and phenoxide bridges. Interchain antiferromagnetic couplings via aromatic ring pathways operate over a Co-Co length shorter than ∼10.9 Å, resulting in a field-induced metamagnetic transition, while being absent over lengths longer than ∼14.7 Å.

The American Joint Committee for Cancer has adopted a size-based T stage system (eighth edition) for pancreatic ductal adenocarcinoma (PDAC), defined as follows: pT1≤2 cm (pT1a≤0.5 cm, pT1b>0.5 and<1 cm, and pT1c 1-2 cm); pT2>2 and ≤4 cm; and pT3> 4 cm. However, the prognostic value of this new T staging system has not been validated in patients who underwent pancreaticoduodenectomy (PD) after neoadjuvant therapy. In this study, we analyzed 398 PDAC patients who underwent neoadjuvant therapy and PD at our institution from 1999 to 2012...

OBJECTIVES: We sought to evaluate the effectiveness and safety of utilizing radiotherapy (RT) with standard fractionation, with or without intraoperative radiotherapy (IORT), to treat locally recurrent rectal cancer (LRRC). METHODS: Retrospective review of 25 patients with LRRC treated with standard fractionation RT from 2005-2011. Fifteen patients (60%) had prior pelvic RT and ten (40%) had synchronous metastases. The median equivalent dose in 2 Gy fractions was 30 Gy and 49...

Implications of assessing the proximal and far para-tracheal or sub-carinal nodes (para-tracheal [PTN] or sub-carinal [SCN]) associated with lower primary esophageal carcinomas (ECs) are unclear. To evaluate the value of endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) for PTN and SCN, we analyzed results by positron emission tomography (PET) avidity, 4 EUS node malignancy features, and EUS-FNA results in all patients with Siewert's I or II EC. Of 133 patients (PTN, n=102; SCN, n=31) with EUS-FNA, 47 (35%) patients had malignant node, leading to treatment modifications...

While molecular subgrouping has revolutionized medulloblastoma classification, the extent of heterogeneity within subgroups is unknown. Similarity network fusion (SNF) applied to genome-wide DNA methylation and gene expression data across 763 primary samples identifies very homogeneous clusters of patients, supporting the presence of medulloblastoma subtypes. After integration of somatic copy-number alterations, and clinical features specific to each cluster, we identify 12 different subtypes of medulloblastoma...

To expand upon our previous observation that HIV-1 Gag-specific IgG antibodies were highest in HIV controllers not carrying HLA-B*57:01, we analysed these antibodies in a larger cohort of viremic controllers (VCs) or elite controllers (ECs) considering carriage of 'protective' HLA-B alleles. HIV-1 p24-specific IgG1 and IgG2 antibodies were higher only in HLA-B*57:01 VCs but there were no differences in ECs. Associations of HIV-1 gp140-specific IgG antibodies with HLA-B*57:01 carriage were inconsistent amongst VCs and ECs...

The cyanotic congenital heart diseases are a rare and heterogeneous group of disorders, often requiring urgent neonatal management. Although echocardiography is the mainstay for imaging, continued technological advances have expanded the role for computed tomography and magnetic resonance imaging, helping to limit invasive cardiac catheterization. In this article, the authors review the broad spectrum of cyanotic congenital heart disease, focusing on the utility of advanced noninvasive imaging modalities while highlighting key clinical features and management considerations...

Angiotensin system inhibitors (ASIs) can improve prognosis in multiple cancer types, including pancreatic ductal adenocarcinoma (PDAC). However, no study has examined the effect of ASIs alone or combined with adjuvant chemotherapy in resected PDAC patients.<br /><br />Experimental Design: We performed an analysis of the records of ASI users and non-user patients with PDAC seen at Massachusetts General Hospital between January 2006 and December 2010. To identify mechanisms of ASIs in PDAC, we performed RNA-Seq of resected primary lesions...

OBJECTIVE In 2004, the WHO classified atypical pituitary adenoma as a distinct adenoma subtype. However, the clinical significance of this distinction remains undetermined. The authors sought to define patient characteristics, tumor features, and treatment outcomes associated with atypical pituitary adenoma. METHODS The authors reviewed records of patients who underwent resection of pituitary adenoma at the University of California, San Francisco, between 2007 and 2014. Per institutional protocol, adenomas exhibiting mitotic activity underwent evaluation for all 3 markers of atypicality (mitotic index, extensive p53 staining, and MIB-1 index ≥ 3%)...

Background:JAK2 V617F mutation (mut) in acute myeloid leukemia (AML) is rare. We describe the clinicopathologic findings of a single-institution series of 11 de novo AML cases with JAK2 V617. Methods: We identified cases of de novo AML with JAK2 V617F over a 10-year period. We reviewed diagnostic peripheral blood and bone marrow (BM) morphologic, cytogenetic, and molecular studies, including next-generation sequencing. The control group consisted of 12 patients with JAK2 wild-type (wt) AML matched for age, sex, and diagnosis...

Parahydrogen induced polarization (PHIP) is a method for enhancing NMR sensitivity. The pairwise addition of parahydrogen in aqueous medium by heterogeneous catalysts can lead to applications in chemical and biological systems. Polarization enhancement can be transferred from 1H to 13C for longer lifetimes by use of zero field cycling. In this work, water-dispersible N-acetylcysteine- and L-cysteine-stabilized palladium nanoparticles are introduced and carbon polarizations up to two orders of magnitude higher than previous aqueous heterogeneous PHIP systems are presented...
