REVIEW
David Wu, Megan S Lim, Elaine S Jaffe
The term Castleman disease encompasses several distinct lymphoproliferative disorders with different underlying disease pathogenesis, and clinical outcomes. It includes unicentric and multicentric diseases with limited versus significant systemic symptoms, respectively. Importantly, the histopathologic features encountered in the various forms of Castleman disease are diverse, and for the most part, lack specificity, because they are seen to varying degrees in different clinical variants of Castleman disease, and in reactive (autoimmune/infectious) and malignant (lymphoma) contexts...

Leishmania is a single-celled eukaryotic parasite afflicting millions of humans worldwide, with current therapies limited to a poor selection of drugs that mostly target elements in the parasite's cell envelope. Here we determined the atomic resolution electron cryo-microscopy (cryo-EM) structure of the Leishmania ribosome in complex with paromomycin (PAR), a highly potent compound recently approved for treatment of the fatal visceral leishmaniasis (VL). The structure reveals the mechanism by which the drug induces its deleterious effects on the parasite...

REVIEW
Caoimhe Egan, Elaine S Jaffe
Benign and malignant proliferations of histiocytes and dendritic cells may be encountered in lymph nodes. Reactive histiocytic and dendritic cell infiltrates occur in response to diverse stimuli and in addition to causing lymphadenopathy, may be present unexpectedly in lymph nodes excised for other indications. This review summarizes the pathogenesis and histopathological features of the various non-neoplastic histiocytic and dendritic cell infiltrates that can occur in lymph nodes.

Eduardo Luiz Rossini, Maria Izabel Milani, Emanuel Carrilho, Leonardo Pezza, Helena Redigolo Pezza
In this paper, we describe a validated paper-based microfluidic analytical device for the simultaneous quantification of two important biomarkers of renal function in urine. This paper platform provides an inexpensive, simple, and easy to use colorimetric method for the quantification of creatinine (CRN) and uric acid (UA) in urine samples. The microfluidic paper-based analytical device (μPAD) consists of a main channel with three identical arms, each containing a circular testing zone and a circular uptake zone...

A major challenge is to understand maladaptive changes in ion channels that sets neurons on a course towards epilepsy development. Voltage- and calcium-activated K+ (BK) channels contribute to early spike timing in neurons, and studies indicate that the BK channel plays a pathological role in increasing excitability early after a seizure. Here, we have investigated changes in BK channels and their accessory β4 subunit (KCNMB4) in dentate gyrus (DG) granule neurons of the hippocampus, key neurons that regulate excitability of the hippocampus circuit...

Leishmania spp. are medically important unicellular parasites transmitted by phlebotomine sand flies. The World Health Organization recently highlighted the importance of reliable diagnostic tools for leishmaniasis. Our study of human infection was conducted in two endemic foci of Leishmania tropica in the Galilee region, northern Israel. Elevated anti-Leishmania antibodies were present in the majority (78.6%) of L. tropica-PCR positive individuals. Moreover, the enzyme-linked immunosorbent assay showed high sensitivity, specificity, and negative and positive predictive values (ranging between 73% and 79%), thus fulfilling the basic requirement for future development of a serodiagnostic and screening tool...

BACKGROUND : Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals. METHODS : This was a multicenter pragmatic stepped-wedge before-and-after trial in 7 New Zealand acute care hospitals with 31 332 patients investigated for suspected ACS with serial troponin measurements...

OBJECTIVE: Adults presenting to pediatric emergency departments are transferred to general emergency departments in proportions between 20% and 60%. How illness severity is related to the decision to transfer is poorly understood. We compared the proportion of adults with emergent and nonemergent conditions with respect to their final disposition. We also determined characteristics associated with transfer. METHODS: We conducted a retrospective review of the electronic medical record and identified all patients 25 years and older presenting to a large urban freestanding pediatric emergency department from 2008 to 2013...

We present a detailed report of an awake craniotomy for recurrent third ventricular colloid cyst in a patient with severe pulmonary arterial hypertension in the setting of Eisenmenger syndrome, performed 6 weeks after we managed the same patient for a more conservative procedure. This patient has a high risk of perioperative mortality and may be particularly susceptible to perioperative hemodynamic changes or fluid shifts. The risks of general anesthesia induction and emergence must be balanced against the risks inherent in an awake craniotomy on a per case basis...

Mortality associated with high-risk pulmonary embolism (PE) remains high. Extra-corporeal membrane oxygenation (ECMO) allows for acute hemodynamic stabilization and potentially for administration of other disease process altering therapies. We sought to compare two eras: pre-ECMO and post-ECMO in relation to high-risk PE treatment and mortality. A single-center retrospective chart review was conducted of high-risk PE patients. High-risk PE was defined as acute PE and cardiac arrest or shock. A total of 60 patients were identified, 31 in the pre-ECMO era and 29 in the post-ECMO era...

We examined 18,654 patients who underwent cardiac catheterization in a single center to clarify the association between catheterization indication, body mass index (BMI), and long-term survival over a mean follow-up of 81 months. Patients were grouped by indication for catheterization: (a) acute coronary syndromes (ACS), 7,426 patients; (b) coronary artery disease (CAD) evaluation in stable clinical presentation, 6,911 patients; and (c) primarily non-CAD cardiac evaluations, 4,317 patients. Compared with normal weight, overweight and obesity (but not morbid obesity) was associated with lower risk of long-term mortality...

Although Escherichia coli has been engineered to perform N-glycosylation of recombinant proteins, an optimal glycosylating strain has not been created. By inserting a codon optimised Campylobacter oligosaccharyltransferase onto the E. coli chromosome, we created a glycoprotein platform strain, where the target glycoprotein, sugar synthesis and glycosyltransferase enzymes, can be inserted using expression vectors to produce the desired homogenous glycoform. To assess the functionality and glycoprotein producing capacity of the chromosomally based OST, a combined Western blot and parallel reaction monitoring mass spectrometry approach was applied, with absolute quantification of glycoprotein...

Isolated MYC rearrangement without other recurrent genetic abnormalities is rare in B lymphoblastic leukemia/lymphoma (B-ALL/LBL), with most cases reported in pediatric patients. We report 3 adult cases with lymphoblasts showing a precursor B cell immunophenotype, and isolated MYC/IGH translocation. All 3 cases occurred in male patients with initial presentation of diffuse lymphadenopathy. Cases 1 and 2 had B-ALL with significantly increased lymphoblasts in peripheral blood and bone marrow. Case 3, a patient with human immunodeficiency virus infection, had the diagnosis of B-LBL made on a retroperitoneal lymph node biopsy and had no peripheral blood or bone marrow involvement...
