Hospitalizations for Fungal Infections after Initiation of Chronic Dialysis in the United States

Aims: Hospitalized fungal infections are reported frequently in renal transplant recipients and peritoneal dialysis patients, but the frequency of hospitalized fungal infections in dialysis patients has not been studied in a national population. Methods: 327,993 dialysis patients in the United States Renal Data System initiated from January 1, 1992 to June 30, 1997 were analyzed in a retrospective registry study of fungal infections (based on ICD9 Coding). Results: Dialysis patients had an age-adjusted incidence ratio for fungal infections of 9.80 (95% confidence interval (CI) 6.34–15.25)) compared to the general population in 1996 (the National Hospital Discharge Survey). Candidiasis accounted for 79% of all fungal infections, followed by cryptococcosis (6.0%) and coccidioidomycosis (4.1%). In multivariate analysis, fungal infections were associated with earlier year of dialysis, diabetes, female gender, decreased weight and serum creatinine at initiation of dialysis, chronic obstructive lung disease and AIDS. In Cox regression analysis the hazard ratio for mortality of fungal infections was 1.35 (95% CI 1.28–1.42). Conclusions: Dialysis patients were at increased risk for fungal infections compared to the general population, which substantially decreased patient survival. Female and diabetic patients were at increased risk for fungal infections. Although candidiasis was the dominant etiology of fungal infections, the frequency of cryptococcosis and coccidioidomycosis were higher than previously reported.
Characteristics and Risk Factors of Late-onset Bloodstream Infection Beyond 6 Months After Liver Transplantation in Children

Background: Bloodstream infection (BSI) is a major cause of morbidity and mortality after pediatric liver transplantation (LT). However, most studies have focused on BSI occurring within a few months after LT. In this study, we evaluated the characteristics of BSI occurring beyond 6 months after pediatric LT. Methods: We conducted a retrospective cohort study at a pediatric LT center in Japan from November 2005 to March 2016. We evaluated the causative organisms and site of late-onset BSI in children ⩽ 18 years of age. The risk factors for developing late-onset BSI and the associations of late-onset BSI with long-term outcomes were also evaluated. Results: Three hundred forty cases of LT were evaluated. Thirty-eight BSI developed in 29 (9%) LT recipients. There were 42 organisms (nine Gram-positive cocci, 33 Gram-negative rods) isolated from the blood cultures of recipients with late-onset BSI. The most frequent sites of late-onset BSI was intraabdominal infection (18/38; 47%). There were also 14 (39%) episodes with no apparent focus. In multivariate analysis, a prolonged operative time > 12 hours (odds ratio [OR] = 3.55; P = 0.04) and biliary stenosis (OR = 4.60; P = 0.006) were independent risk factors for developing late-onset BSI. Late-onset BSI was associated with increased retransplantation rate (P = 0.04) and mortality (P < 0.001). Conclusion: Late-onset BSI developed in 9% of recipients after pediatric LT. Gram-negative rods accounted for the majority of late-onset BSI as a consequence of abdominal infection, but the focus was often unclear. Prolonged operative time at LT and biliary stenosis were independent risk factors for developing late-onset BSI.
Coffee drinking and colorectal cancer and its subsites: A pooled analysis of 8 cohort studies in Japan

Coffee is a rich source of bioactive compounds that have potential anticarcinogenic effects. However, it remains unclear whether coffee drinking is associated with colorectal cancer. Also, despite different etiological factors involved in gut physiology, few studies have investigated this association by anatomical site of the lesion. To address these issues, this study examined the association between coffee drinking and colorectal cancer in a pooled analysis from 8 cohort studies conducted in Japan. Among 320,322 participants followed up for 4,503,274 person‐years, 6,711 incident colorectal cancer cases were identified. Study‐specific hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models and then pooled using the random effects model. Coffee drinking was not materially associated with colorectal cancer risk in men or women (pooled HR 0.92, 95% CI 0.82–1.03 in men and pooled HR 0.90, 95% CI 0.76–1.07 in women). Analysis by subsite showed a lower risk of colon cancer among female drinkers of ≥3 cups coffee/day (pooled HR 0.80, 95% CI 0.64–0.99). There was no such association in men. Coffee drinking was not associated with risk of rectal cancer in men or women. Results were virtually the same among never smokers except for an increased risk of rectal cancer associated with frequent coffee consumption. Coffee drinking may be associated with lower risk of colon cancer in Japanese women.
Oxytocin Induces Apical and Basolateral Redistribution of Aquaporin-2 in Rat Kidney

The aquaporin-2 (AQP2) water channel is mainly located in the apical plasma membrane of collecting duct epithelial cells, but there has been some evidence of a moderate amount of basolateral localization of AQP2 at least in the inner medullary collecting duct (IMCD). Previous in vitro microperfusion studies showed that oxytocin has an antidiuretic action, most likely mediated by the vasopressin V2 receptor (V2R) in rat IMCD. By using immunohistochemistry in kidneys from male Sprague-Dawley rats, we observed acute effects of oxytocin on AQP2 localization which were prevented by a V2R antagonist. After intraperitoneal administration of oxytocin (10 U), immunohistochemistry of IMCD revealed that AQP2 was shifted from diffuse cytoplasmic localization in controls to the apical and basolateral membrane domains in oxytocin-treated rats. This pattern of AQP2 redistribution was noted in connecting tubule, cortical collecting duct and outer medullary collecting duct as well as in IMCD, although the tendency to basolateral localization was somewhat less. The pretreatment using a V2R antagonist blocked redistribution of AQP2 in response to oxytocin. We conclude that oxytocin induces a V2R-mediated redistribution of AQP2-containing cytoplasmic vesicles to both apical and basolateral plasma membrane domains in rat kidney. Oxytocin may be one of the factors that accounts for vasopressin-independent AQP2 targeting in the kidney.
Modeling Williams syndrome with induced pluripotent stem cells

ABSTRACT The development of induced pluripotent stem cells (iPSCs) like never before has opened novel opportunity to study diseases in relevant cell types. In our recent study, Williams syndrome (WS), a rare genetic neurodevelopmental disorder, that is caused by hemizygous deletion of 25–28 genes on chromosome 7, is of interest because of its unique cognitive and social profiles. Little is known about haploinsufficiency effect of those deleted genes on molecular and cellular phenotypes at the neural level due to the lack of relevant human cellular model. Using the cellular reprogramming approach, we reported that WS iPSC-derived neural progenitor cells (NPCs) has increased apoptosis and therefore increased doubling time, which could be rescued by complementation of frizzled 9, one of the genes typically deleted in WS. Moreover, WS iPSC-derived CTIP2-positive pyramidal neurons exhibit morphologic alterations including longer total dendrites and increasing dendritic spine number. In addition, WS iPSC-derived neurons show an increase in calcium transient frequency and synchronized activity likely due to increased number of dendritic spines and synapses. Our work integrated cross-level data from genetics to behavior of WS individuals and revealed altered cellular phenotypes in WS human NPCs and neurons that could be validated in other model systems such as magnetic resonance imaging (MRI) in live subjects and postmortem brain tissues.
Role of single nucleotide polymorphisms in pharmacogenomics and their association with human diseases

Abstract Global statistical data shed light on an alarming trend that every year thousands of people die due to adverse drug reactions as each individual responds in a different way to the same drug. Pharmacogenomics has come up as a promising field in drug development and clinical medication in the past few decades. It has emerged as a ray of hope in preventing patients from developing potentially fatal complications due to adverse drug reactions. Pharmacogenomics also minimizes the exposure to drugs that are less/non-effective and sometimes even found toxic for patients. It is well reported that drugs elicit different responses in different individuals due to variations in the nucleotide sequences of genes encoding for biologically important molecules (drug-metabolizing enzymes, drug targets and drug transporters). Single nucleotide polymorphisms (SNPs), the most common type of polymorphism found in the human genome is believed to be the main reason behind 90% of all types of genetic variations among the individuals. Therefore, pharmacogenomics may be helpful in answering the question as to how inherited differences in a single gene have a profound effect on the mobilization and biological action of a drug. In the present review, we have discussed clinically relevant examples of SNP in associated diseases that can be utilized as markers for “better management of complex diseases” and attempted to correlate the drug response with genetic variations. Attention is also given towards the therapeutic consequences of inherited differences at the chromosomal level and how associated drug disposition and/or drug targets differ in various diseases as well as among the individuals.
Choosing a Physician on Social Media: Comments and Ratings of Users are More Important than the Qualification of a Physician

ABSTRACT Social media provides users with descriptions, comments, and ratings from others to facilitate decision-making. In this study, we want to assess how users make decisions with the help of the tools provided by social media. In order to do so, we simulate a physician rating website in which participants had to choose one physician among four options in a task of 20 trials. For this, we used a choice-based conjoint design, which allowed us to experimentally observe which features of social media have more impact on the decisions of the participants. Furthermore, personal characteristics of the participants, such as executive functions, cognitive styles, and personality traits, were measured. We found that the subjective features of social media, such as the comments and ratings provided by other users, have a greater impact on the decision of the participants when compared with the objective characteristics such as experience or specialty. Regarding the personal characteristics, we found that the executive functions cognitive flexibility and categorization were higher for those participants who preferred objective features (e.g. availability, specialty, experience of the physician) than for those participants who preferred subjective features. The results of the current study help understand how users make decisions with social media tools. We also stress the importance of the comments and ratings of users in decision making on social media. Furthermore, we suggest considering these results in the fields of recommender systems and information retrieval, in order to improve the human–computer interaction in platforms that use recommendations as an important part of the decision-making process of users.
Experience With the Enlite Sensor in a Multicenter Pediatric Study

Purpose The purpose of this article is to outline the experience of certified diabetes educators (CDEs) using the Enlite continuous glucose monitoring sensor system in a pediatric multicenter randomized controlled trial. Continuous glucose monitoring (CGM) is becoming popular as a tool for educators and families to improve glycemic control. CGM can be a valuable educational tool to demonstrate to the user the impact of insulin dosing and effects of physical activity, food intake, and other life events such as work, illness, and stress on their glycemic control. The authors will share education tips and practical applications for diabetes educators to facilitate education and sustained use of Enlite glucose sensors in children and adolescents using insulin pump therapy. Conclusions The Enlite glucose sensor is a comfortable and user-friendly device. Improvements to both the insertion device and the Enlite glucose sensor have resulted in improved level of comfort on insertion and with ongoing wear, which may translate into greater adherence and effectiveness.
EphA2 as a Diagnostic Imaging Target in Glioblastoma: A Positron Emission Tomography/Magnetic Resonance Imaging Study

Noninvasive imaging is a critical technology for diagnosis, classification, and subsequent treatment planning for patients with glioblastoma. It has been shown that the EphA2 receptor tyrosine kinase (RTK) is overexpressed in a number of tumors, including glioblastoma. Expression levels of Eph RTKs have been linked to tumor progression, metastatic spread, and poor patient prognosis. As EphA2 is expressed at low levels in normal neural tissues, this protein represents an attractive imaging target for delineation of tumor infiltration, providing an improved platform for image-guided therapy. In this study, EphA2-4B3, a monoclonal antibody specific to human EphA2, was labeled with 64Cu through conjugation to the chelator 1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA). The resulting complex was used as a positron emission tomography (PET) tracer for the acquisition of high-resolution longitudinal PET/magnetic resonance images. EphA2-4B3-NOTA-64Cu images were qualitatively and quantitatively compared to the current clinical standards of [18F]FDOPA and gadolinium (Gd) contrast–enhanced MRI. We show that EphA2-4B3-NOTA-64Cu effectively delineates tumor boundaries in three different mouse models of glioblastoma. Tumor to brain contrast is significantly higher in EphA2-4B3-NOTA-64Cu images than in [18F]FDOPA images and Gd contrast–enhanced MRI. Furthermore, we show that nonspecific uptake in the liver and spleen can be effectively blocked by a dose of nonspecific (isotype control) IgG.
Comparison of the effect of a hyaluronate–trehalose solution to hyaluronate alone on Ocular Surface Disease Index in patients with moderate to severe dry eye disease

Abstract Objective: To describe a post hoc analysis comparing the effect of a hyaluronic acid (HA)–trehalose solution to an established eyedrop solution containing HA alone using Ocular Surface Disease Index (OSDI) score <19 as a threshold for moderate to severe dry eye disease (DED). Methods: A phase III, randomized, controlled, single-blind, multicenter study was conducted in France and Tunisia to evaluate the efficacy and safety of HA–trehalose (N = 52) and HA (N = 53) administered for 84 days. Eligible patients had moderate to severe DED with OSDI ≥18. Here the results of a post hoc analysis of the percentage of patients with OSDI <19 on Day 35 and Day 84 are reported. Results: Significantly more patients had OSDI <19 at Day 84 in the HA–trehalose group than in the HA group (78.8% versus 58.5%; p = .025). At Day 35, more patients had OSDI <19 in the HA–trehalose group than in the HA group, but this difference was not statistically significant. Furthermore, approximately twice as many patients in the HA group (41.5%) still had OSDI 19–100 at Day 84 compared to the HA–trehalose group (21.2%). Conclusions: This data supports the addition of trehalose to HA-containing eyedrop solutions to provide better symptomatic relief from moderate to severe DED, based on an OSDI score of <19 after 84 days of treatment.
Measuring reliable change in cognition using the Edinburgh Cognitive and Behavioural ALS Screen (ECAS)

Abstract Background: Cognitive impairment affects approximately 50% of people with amyotrophic lateral sclerosis (ALS). Research has indicated that impairment may worsen with disease progression. The Edinburgh Cognitive and Behavioural ALS Screen (ECAS) was designed to measure neuropsychological functioning in ALS, with its alternate forms (ECAS-A, B, and C) allowing for serial assessment over time. Objective: The aim of the present study was to establish reliable change scores for the alternate forms of the ECAS, and to explore practice effects and test-retest reliability of the ECAS’s alternate forms. Method: Eighty healthy participants were recruited, with 57 completing two and 51 completing three assessments. Participants were administered alternate versions of the ECAS serially (A-B-C) at four-month intervals. Intra-class correlation analysis was employed to explore test-retest reliability, while analysis of variance was used to examine the presence of practice effects. Reliable change indices (RCI) and regression-based methods were utilized to establish change scores for the ECAS alternate forms. Results: Test-retest reliability was excellent for ALS Specific, ALS Non-Specific, and ECAS Total scores of the combined ECAS A, B, and C (all > .90). No significant practice effects were observed over the three testing sessions. RCI and regression-based methods produced similar change scores. Conclusion: The alternate forms of the ECAS possess excellent test-retest reliability in a healthy control sample, with no significant practice effects. The use of conservative RCI scores is recommended. Therefore, a change of ≥8, ≥4, and ≥9 for ALS Specific, ALS Non-Specific, and ECAS Total score is required for reliable change.
Increase in avoidable hospital admissions after the Great East Japan Earthquake

Background The Great East Japan Earthquake and subsequent tsunami and nuclear disaster on 11 March 2011 had a short-term influence on the increase in emergency department visits and hospital admissions due to various diseases. However, it remains unclear whether the earthquake and tsunami disaster affected the long-term health conditions of people in the affected areas. Methods Using a national inpatient database in Japan, we investigated people's ambulatory care sensitive conditions (ACSCs), which are defined as conditions for which effective management and treatment should prevent admission to a hospital. We compared the number of admissions for ACSCs before-quake (July 2010 to February 2011) with after-quake (July 2012 to February 2013) periods in the disaster area compared with other areas using a difference-in-differences design. Linear regression models with the interaction between periods and areas were used to estimate the impact of the earthquake on admissions for ACSCs. Results No significant difference in difference was seen in preventable ACSCs (where immunisation and other interventions can prevent illness) or chronic ACSCs (where effective care can prevent flare-ups), while acute ACSCs (where early intervention can prevent more serious progression) increased significantly (3.3 admissions per 100 000 population; 95% CI 0.4 to 6.3; p=0.028). Conclusions Preventable and chronic ACSCs may have increased just after the earthquake and then immediately decreased. However, avoidable admissions due to acute ACSCs remained high in the long term after the earthquake and tsunami disaster.
All-fiber mode converter based on long-period fiber gratings written in few-mode fiber.

We investigated an all-fiber mode converter based on long-period fiber gratings (LPFGs) written in the few-mode fiber. Mode conversion between the fundamental core mode and different higher-order core modes (LP11, LP21, and LP02 modes) can be realized via a single LPFG with an efficiency of 99% at the resonance wavelength. Moreover, optimized mode conversion between the LP01 and LP21 modes can be realized by cascading two LPFGs with different grating pitches. The maximum conversion efficiency is estimated to be ∼99.5% at 1553 nm. The orbital angular momentum states with different topological charges (±1,±2) are demonstrated experimentally. The all-fiber LPFG mode converters could have promising applications in the mode-division multiplexing optical communications.
Role of sialic acid‐containing glycans of matrix metalloproteinase‐9 (MMP‐9) in the interaction between MMP‐9 and staphylococcal superantigen‐like protein 5

Staphylococcal superantigen‐like proteins (SSL) show no superantigenic activity but have recently been considered to act as immune suppressors. It was previously reported that SSL5 bound to P‐selectin glycoprotein ligand‐1 (PSGL‐1) and matrix metalloproteinase (MMP)‐9, leading to inhibition of leukocyte adhesion and invasion. These interactions were suggested to depend on sialic acid‐containing glycans of MMP‐9, but the roles of sialic acids in the interaction between SSL5 and MMP‐9 are still controversial. In the present study, we prepared recombinant glutathione S‐transferase‐tagged SSL5 (GST‐SSL5) and analyzed its binding capacity to MMP‐9 by pull‐down assay after various modifications of its carbohydrate moieties. We observed that GST‐SSL5 specifically bound to MMP‐9 from a human monocytic leukemia cell line (THP‐1 cells) and inhibited its enzymatic activity in a concentration‐dependent manner. After MMP‐9 was treated with neuraminidase, its binding activity towards GST‐SSL5 was markedly decreased. Furthermore, recombinant MMP‐9 produced by sialic acid‐deficient Lec2 mutant cells showed much lower affinity for SSL5 than that produced by wild‐type CHO‐K1 cells. Treatment of MMP‐9 with PNGase F to remove N‐glycan resulted in no significant change in the GST‐SSL5/MMP‐9 interaction. In contrast, the binding of GST‐SSL5 to MMP‐9 secreted from THP‐1 cells cultured in the presence of an inhibitor for the biosynthesis of O‐glycan (benzyl‐GalNAc) was weaker than the binding of GST‐SSL5 to MMP‐9 secreted from untreated cells. These results strongly suggest the importance of the sialic acid‐containing O‐glycans of MMP‐9 for the interaction of MMP‐9 with GST‐SSL5.
The RES complex is required for efficient transformation of the precatalytic B spliceosome into an activated Bact complex

In this study, Bao et al. investigated the role of the trimeric retention and splicing (RES) complex protein Snu17 and its interaction partners during spliceosome assembly and catalytic activation. Their findings reveal novel roles for the RES complex proteins during spliceosome activation as well as a potential proofreading function of the spliceosomal ATPase Prp2.
