Three-year Follow-up on the Safety and Effectiveness of Rituximab Plus Chemotherapy as First-Line Treatment of Diffuse Large B-Cell Lymphoma and Follicular Lymphoma in Real-World Clinical Settings in China: A Prospective, Multicenter, Noninterventional Study

Background: Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated. Methods: A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation. Results: In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50–67%) for DLBCL patients and 46% (95% CI: 20–69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively. Conclusions: R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.

Evidence of EBV infection in lymphomas diagnosed in Lusaka, Zambia

Introduction Epstein-Barr virus (EBV) is a ubiquitous virus that infects more than 90% of the world's population, and is implicated in lymphoma pathogenesis. However, in Zambia during the diagnosis of these lymphomas, the association of the virus with the lymphomas is not established. Since most patients with lymphomas have poor prognosis, the identification of the virus within the lymphoma lesion will allow for more targeted therapy. The aim of this study was to provide evidence of the presence of the EBV in lymphomas diagnosed at the University Teaching Hospital (UTH) in Lusaka, Zambia. Methods One hundred and fifty archival formalin-fixed paraffin embedded suspected lymphoma tissues stored over a 4-year period in the Histopathology Laboratory at the UTH in Lusaka, Zambia, were analysed. Histological methods were used to identify the lymphomas, and the virus was detected using Polymerase Chain Reaction (PCR). Subtyping of the virus was achieved through DNA sequencing of the EBNA-2 region of the viral genome. Chi square or fisher's exact test was used to evaluate the association between EBV status, type of lymphoma and gender. Results The majority of the lymphomas identified were non-Hodgkin's lymphoma (NHL) (80%) followed by Hodgkin's lymphoma (HL) (20%). EBV was detected in 51.8% of the cases, 54.5% of which were associated with NHL cases, while 40.9% associated with HL cases. The predominant subtype of the virus in both types of lymphomas was subtype 1. One of the lymphoma cases harboured both subtype 1 and 2 of the virus. Conclusion This study showed that EBV is closely associated with lymphomas. Therefore, providing evidence of the presence of the virus in lymphoma tissues will aid in targeted therapy. To our knowledge this is the first time such data has been generated in Zambia.
The Helmholtz Method: Using Perceptual Compression to Reduce Machine Learning Complexity

This paper proposes a fundamental answer to a frequently asked question in multimedia computing and machine learning: Do artifacts from perceptual compression contribute to error in the machine learning process and if so, how much? Our approach to the problem is a reinterpretation of the Helmholtz Free Energy formula from physics to explain the relationship between content and noise when using sensors (such as cameras or microphones) to capture multimedia data. The reinterpretation allows a bit-measurement of the noise contained in images, audio, and video by combining a classifier with perceptual compression, such as JPEG or MP3. Our experiments on CIFAR-10 as well as Fraunhofer's IDMT-SMT-Audio-Effects dataset indicate that, at the right quality level, perceptual compression is actually not harmful but contributes to a significant reduction of complexity of the machine learning process. That is, our noise quantification method can be used to speed up the training of deep learning classifiers significantly while maintaining, or sometimes even improving, overall classification accuracy. Moreover, our results provide insights into the reasons for the success of deep learning.

With interest we read the article by Truchetet et al.[1] concerning the presence of anti-carbamylated protein antibodies (anti-CarP) in early arthritis patients in the French ESPOIR cohort. They found anti-CarP positivity was associated with higher disease activity and inflammation at baseline. This article is protected by copyright. All rights reserved.
Automated Characterization of Stenosis in Invasive Coronary Angiography Images with Convolutional Neural Networks

The determination of a coronary stenosis and its severity in current clinical workflow is typically accomplished manually via physician visual assessment (PVA) during invasive coronary angiography. While PVA has shown large inter-rater variability, the more reliable and accurate alternative of Quantitative Coronary Angiography (QCA) is challenging to perform in real-time due to the busy workflow in cardiac catheterization laboratories. We propose a deep learning approach based on Convolutional Neural Networks (CNN) that automatically characterizes and analyzes coronary stenoses in real-time by automating clinical tasks performed during QCA. Our deep learning methods for localization, segmentation and classification of stenosis in still-frame invasive coronary angiography (ICA) images of the right coronary artery (RCA) achieve performance of 72.7% localization accuracy, 0.704 dice coefficient and 0.825 C-statistic in each respective task. Integrated in an end-to-end approach, our model's performance shows statistically significant improvement in false discovery rate over the current standard in real-time clinical stenosis assessment, PVA. To the best of the authors' knowledge, this is the first time an automated machine learning system has been developed that can implement tasks performed in QCA, and the first time an automated machine learning system has demonstrated significant improvement over the current clinical standard for rapid RCA stenosis analysis.
Content overlap analysis of 64 (hypo)mania symptoms among seven common rating scales

Fried ( ) quantified the overlap of items among seven widely used depression rating scales. The analysis revealed substantial heterogeneity of the depressive syndromes and a low overlap among the scales. To our best knowledge, there are no studies evaluating the content overlap of (hypo)mania scales. The goal of our study, therefore, is to quantify the overlap of items among seven widely used (hypo)manic scales, implementing the methodology developed by Fried ( ).
Seroprevalence of ToxocaraCanis in Asthmatic Children and its Relation to the Severity of Diseases - a Case-Control Study

Background: Toxocariasis is a common parasitic infectionworldwide even in developed countries. Through this health problem, the immune system is triggered and the antibody is produced, leading to some hypersensitive situations like asthma. In the present study, we tried to show a correlation between Toxocara Canis (T. canis) seropositivityand asthma in Isfahan city. Methods: This research is a cross-sectional study involving 40 asthmatics and 46 non-asthmatic cases aged 2-18 years. In all cases, T. canis IgG level was measured using enzyme-linked immunosorbent assay (ELISA) and compared between two groups. Results: The seroprevalence of IgG anti-T. canis antibodies were 45%in the asthmatic patients and 21.7% in thecontrols (P= 0.022). The more severe asthmatic patients had significantly more risk for T. canis seropositivity (P= 0.019). In the asthmatic patients, there was a significant correlation between Toxocara seropositivity and goingto park or playground (P= 0.001). Conclusion: In this study, we found a significantly positive serology of T. canis in asthmatic children especially in more severe disease. To verify the etiologic role of Toxocara in asthma, more advanced studies are needed.
Altered resting-state cerebellar-cerebral functional connectivity in obsessive-compulsive disorder

Abstract Background The role of the cerebellum in obsessive-compulsive disorder (OCD) has drawn increasing attention. However, the functional connectivity between the cerebellum and the cerebral cortex has not been investigated in OCD, nor has the relationship between such functional connectivity and clinical symptoms. Methods A total of 27 patients with OCD and 21 healthy controls (HCs) matched on age, sex and education underwent magnetic resonance imaging (MRI). Seed-based connectivity analyses were performed to examine differences in cerebellar-cerebral connectivity in patients with OCD compared with HCs. Associations between functional connectivity and clinical features in OCD were analyzed. Results Compared with HCs, OCD patients showed significantly decreased cerebellar-cerebral functional connectivity in executive control and emotion processing networks. Within the OCD group, decreased functional connectivity in an executive network spanning the right cerebellar Crus I and the inferior parietal lobule was positively correlated with symptom severity, and decreased connectivity in an emotion processing network spanning the left cerebellar lobule VI and the lingual gyrus was negatively correlated with illness duration. Conclusions Altered functional connectivity between the cerebellum and cerebral networks involved in cognitive-affective processing in patients with OCD provides further evidence for the involvement of the cerebellum in the pathophysiology of OCD, and is consistent with impairment in executive control and emotion regulation in this condition.
Accelerated and high‐resolution cardiac T2 mapping through peripheral k‐space sharing

To develop high‐spatial‐resolution cardiac T2 mapping that allows for a reduced acquisition time while maintaining its precision. We implemented and optimized a new golden‐angle radial T2 mapping technique named SKRATCH (Shared k‐space Radial T2 Characterization of the Heart) that shares k‐space peripheries of T2‐weighted images while preserving their contrasts.
Identifying and addressing the limitations of EVAR technology

ABSTRACT Introduction: Endovascular aortic repair (EVAR) has improved over the last two decades. Approximately 80% of the patients presenting with an abdominal aortic aneurysm (AAA) is nowadays primarily treated with EVAR. Areas covered: In this review, the differences between endovascular and open repair, the clinical characteristics needed for EVAR, the role of clinical imaging and the developments in EVAR technology will be discussed. Early mortality is lower in EVAR as compared to open repair, whereas this benefit is lost after 3 years postoperatively. EVAR comes with a high reintervention rate, with endoleak being the most important predictive factor for reintervention. Expanding technical possibilities have allowed surgeons to choose from a palate of endovascular approaches in aneurysm patients with challenging anatomies. Expert commentary: Although EVAR has taken a giant leap forward in development, the new developments have seemed to surpass the long-term limitations with older devices. It is important to start focusing on the current limitations of EVAR, in particular the durability of devices in the human variable anatomic and dynamic environment.
Obesity management among patients with type 2 diabetes and prediabetes: a focus on lifestyle modifications and evidence of antiobesity medications

ABSTRACT Introduction: The prevalence of obesity has increased over the past three decades in the United States and worldwide. This article reviews landmark trials for lifestyle modifications as well as clinical evidence and implications for locaserin, phentermine with topiramate, buproprion with naltrexone, and liraglutide in patients with type 2 diabetes and obesity. Areas covered: A MEDLINE search, from 1970 to May 2017, was conducted using key search terms - lifestyle modifications, antiobesity medication, obesity and diabetes. Published clinical trials, in the English language, with the adult patient population of type 2 diabetes or prediabetes, were reviewed and critiqued. Expert commentary: Lifestyle modifications have shown to prevent the progression to type 2 diabetes mellitus. Pharmacologically, each medication has proven effect on both type 2 diabetes mellitus and obesity, specifically reducing weight from baseline by 4.7 kg, 10.2 kg, 5.0 kg, and 6.4 kg with lorcaserin, phentermine with topiramate, bupropion with naltrexone, and liraglutide, respectively. The most efficacious medication is phentermine with topiramate, but liraglutide has long-term evidence, up to 3 years, particularly in patient with prediabetes. A risk-benefit analysis should be completed to determine which specific medication should be initiated for a patient with type 2 diabetes and obesity.
A prospective study of the epidemiological and clinical patterns of recurrent dermatophytosis at a tertiary care hospital in India

Background: Recurrent and clinically unresponsive dermatophytosis is being increasingly encountered in our country. It runs a protracted course with exacerbations and remissions. However, there is little information regarding the extent of the problem and the characteristics of recurrent dermatophytosis in published literature. Aims: We sought to determine the prevalence, risk factors and clinical patterns of recurrent dermatophytosis in our institution. We also investigated the causative dermatophyte species and antifungal susceptibility patterns in these species. Methods: One hundred and fifty patients with recurrent dermatophytosis attending the outpatient department of the Postgraduate Institute of Medical Education and Research, Chandigarh, India were enrolled in the study conducted from January 2015 to December 2015. A detailed history was obtained in all patients, who were then subjected to a clinical examination and investigations including a wet preparation for direct microscopic examination, fungal culture and antifungal susceptibility tests. Results: Recurrent dermatophytosis was seen in 9.3% of all patients with dermatophytosis in our study. Trichophyton mentagrophytes was the most common species identified (36 patients, 40%) samples followed by T. rubrum (29 patients, 32.2%). In-vitro antifungal susceptibility testing showed that the range of minimum inhibitory concentrations (MIC) on was lowest for itraconazole (0.015–1), followed by terbinafine (0.015–16), fluconazole (0.03–32) and griseofulvin (0.5–128) in increasing order. Limitation: A limitation of this study was the absence of a suitable control group (eg. patients with first episode of typical tinea). Conclusion: Recurrence of dermatophytosis was not explainable on the basis of a high (MIC) alone. Misuse of topical corticosteroids, a high number of familial contacts, poor compliance to treatment over periods of years, and various host factors, seem to have all contributed to this outbreak of dermatophytosis in India.
Comparison of therapeutic response of lycopene and curcumin in oral submucous fibrosis: A randomized controlled trial.

OBJECTIVES To evaluate and compare the therapeutic response of lycopene and curcumin with placebo in patients suffering from oral submucous fibrosis (OSMF) and to correlate the habit variables of smoked and smokeless tobacco products in OSMF. METHODS A randomized placebo-controlled parallel clinical study was conducted on ninety OSMF patients, who were divided into three treatment groups using computer-generated randomization. Group A patients (n = 30) were given curcumin tablet (300 mg) twice daily, Group B patients (n = 30) received lycopene capsules (8 mg) twice daily, and for Group C (n = 30), placebo capsules were given once daily for a period of six months. Both the participant and outcome assessor were blinded. Pre- and post-treatment comparison of mouth opening, burning sensation, tongue protrusion, and cheek flexibility was analyzed at periodic follow-up of 9 months. RESULTS The overall improvement in mouth opening, burning sensation, tongue protrusion, and cheek flexibility was 3.9 ± 4.9 mm, 4.8 ± 2.6, 5.0 ± 7.2 mm, & 0.36 ± 0.71 mm, respectively, for curcumin and 4.1 ± 4.2 mm, 5.0 ± 2.3, 2.4 ± 3.5 mm, & 0.66 ± 0.80 mm, respectively, for lycopene with the p value <0.05. CONCLUSION Statistically significant improvement in clinical findings was observed in both curcumin and lycopene treatment groups in comparison with placebo. However, the therapeutic efficacy of curcumin and lycopene was found to be almost equal in OSMF patients.
Multiple sclerosis as an adverse drug reaction: clues from the FDA Adverse Event Reporting System

ABSTRACT Background: Possible relationship between drug exposure and multiple sclerosis (MS) development is insufficiently investigated, and further challenged by the incomplete understanding of MS etiopathogenesis. The study aims to investigate whether drug exposure could contribute to MS, by analyzing worldwide spontaneous reporting archives of adverse drug reaction (ADRs). Research design and methods: We retrieved information from the US Food and Drug Administration Adverse Event Reporting System (FAERS) over a 13-year period. Reporting odds ratio (ROR) for MS was calculated for each single substance. Disproportionality signals were considered when at least 10 cases were retrieved with a lower limit of the 95% confidence interval (CI) >1. Results: After a customized data-mining process, 3,226 reports of MS were retrieved. ‘Antineoplastic and immunomodulating drugs’ (33% of total reports) were the most frequently reported, with 10 disproportionality signals, including etanercept (445 cases; ROR: 2.48; 95% Cl: 2.24–2.74), adalimumab (329; 2.05; 1.83–2.30), and infliximab (119; 2.25; 1.87–2.70). We also observed signals for drugs acting on hormone balance, bone density, and central nervous system. Conclusion: Our findings suggest that immunomodulatory drugs increase the risk of MS and point out that some other drug classes should be further investigated for this risk.
Late Quaternary climate legacies in contemporary plant functional composition

The functional composition of plant communities is commonly thought to be determined by contemporary climate. However, if rates of climate‐driven immigration and/or exclusion of species are slow, then contemporary functional composition may be explained by paleoclimate as well as by contemporary climate. We tested this idea by coupling contemporary maps of plant functional trait composition across North and South America to paleoclimate means and temporal variation in temperature and precipitation from the Last Interglacial (120 ka) to the present. Paleoclimate predictors strongly improved prediction of contemporary functional composition compared to contemporary climate predictors, with a stronger influence of temperature in North America (especially during periods of ice melting) and of precipitation in South America (across all times). Thus, climate from tens of thousands of years ago influences contemporary functional composition via slow assemblage dynamics.
Brassica rapa hairy root based expression system leads to the production of highly homogenous and reproducible profiles of recombinant human alpha‐L‐iduronidase

Summary The Brassica rapa hairy root based expression platform, a turnip hairy root based expression system, is able to produce human complex glycoproteins such as the alpha—L—iduronidase (IDUA) with an activity similar to the one produced by Chinese Hamster Ovary (CHO) cells. In this article, a particular attention has been paid to the N‐ and O‐glycosylation that characterize the alpha‐L‐iduronidase produced using this hairy root based system. This analysis showed that the recombinant protein is characterized by highly homogeneous post translational profiles enabling a strong batch to batch reproducibility. Indeed, on each of the 6 N‐glycosylation sites of the IDUA, a single N‐glycan composed of a core Man3GlcNAc2 carrying one beta(1,2)‐xylose and one alpha(1,3)‐fucose epitope (M3XFGN2) was identified, highlighting the high homogeneity of the production system. Hydroxylation of proline residues and arabinosylation were identified during O‐glycosylation analysis, still with a remarkable reproducibility. This platform is thus positioned as an effective and consistent expression system for the production of human complex therapeutic proteins.
Propagule Pressure Build-Up by the Invasive Hymenoscyphus fraxineus Following Its Introduction to an Ash Forest Inhabited by the Native Hymenoscyphus albidus

Dieback of European ash, caused by the ascomycete Hymenoscyphus fraxineus originating from Asia, has rapidly spread across Europe, and is threatening this keystone tree at a continental scale. High propagule pressure is characteristic to invasive species. Consistently, the enormous production of windborne ascospores by H. fraxineus in an ash forest with epidemic level of disease obviously facilitates its invasiveness and long distance spread. To understand the rate of build-up of propagule pressure by this pathogen following its local introduction, during 2011–2017 we monitored its sporulation at a newly infested ash stand in south-western Norway characterized with mild winters and cool summers. We also monitored the propagule pressure by Hymenoscyphus albidus, a non-pathogenic native species that competes for the same sporulation niche with H. fraxineus. During the monitoring period, crown condition of ash trees had impaired, and 20% of the dominant trees were severely damaged in 2017. H. fraxineus showed an exponential increase in spore production between 2012 and 2015, followed by drastic decline in 2016 and 2017. During 2011–2013, the two Hymenoscyphus species showed similar sporulation level, but thereafter spores of H. albidus were no longer detected. The data suggest that following local introduction, the population of H. fraxineus reaches rapidly an exponential growth stage if the local weather conditions are favorable for ascomata maturation across years. In the North Atlantic climate, summer temperatures critically influence the pathogen infection pressure, warm summers allowing the population to grow according to its biotic potential, whereas cold summers can cause a drastic decline in propagule pressure.
