#1
Vincent H J F Mooren, Michiel W P Bleeker, Jakko van Ingen, Mirjam H A Hermans, Peter C Wever
A disseminated peritoneal dialysis-related Mycobacterium abscessus infection is very rare. M. abscessus belongs to the rapidly growing mycobacteria and can be misidentified as a diphtheroid bacterium, which in our case delayed diagnosis and optimal treatment. Due to intrinsic resistance to most antimicrobials, therapeutic options in M. abscessus infections are limited. Infection often leads to catheter loss. A fatal outcome, like in our case, is not exceptional.

Hypersensitivity reactions (HSR) to pegylated liposomal doxorubicin (PLD; Caelyx(®)) have been reported, and symptoms usually resolve with drug withdrawal. However, the risk of relapse of severe HSR and prevention remain poorly described. To report the management and outcome in four patients with HSR due to PLD. Patient characteristics, premedication regimen, rate of infusion, time between onset and HSR, clinical manifestations, and management were documented. A first cycle of PLD was received for cutaneous T-cell lymphoma (n = 3) and Kaposi sarcoma (n = 1)...

The characteristics of patients with dermatitis herpetiformis (DH) in France is poorly documented. Furthermore, the risk of fractures and bone mineral density (BMD) in DH remain under-described, and recommendations for systematic screening for osteoporosis in DH are lacking. To describe the characteristics of DH in a large French cohort and evaluate the association between BMD and features of osteoporosis. Patients were recruited from the French Association of Gluten Intolerants (AFDIAG) and a single university dermatology department...

Site-specific histone ubiquitylation plays a central role in orchestrating the response to DNA double-strand breaks (DSBs). DSBs elicit a cascade of events controlled by the ubiquitin ligase RNF168, which promotes the accumulation of repair factors such as 53BP1 and BRCA1 on the chromatin flanking the break site. RNF168 also promotes its own accumulation, and that of its paralog RNF169, but how they recognize ubiquitylated chromatin is unknown. Using methyl-TROSY solution NMR spectroscopy and molecular dynamics simulations, we present an atomic resolution model of human RNF169 binding to a ubiquitylated nucleosome, and validate it by electron cryomicroscopy...

Magnetic inequivalence of nuclear spins is well known to cause additional splittings that complicate spectral analysis. Here, we present an extraordinary case of magnetic inequivalence, manifested in the 13-spin system of a (13)C,(15)N-labeled trimethylated amine. All methyl group protons are chemically equivalent due to the molecular symmetry, but not all are magnetically equivalent as they have different (1)JCH and (3)JCH couplings. In general, spectra of such a large spin system can be expected to be extremely complicated by the presence of hundreds if not thousands of extra lines, caused by the strong coupling between inequivalent nuclei...

BACKGROUND: High doses of corticosteroids are considered the standard treatment for pemphigus. Because long-term corticosteroid treatment can cause severe and even life-threatening side-effects in patients with this disease, we assessed whether first-line use of rituximab as adjuvant therapy could improve the proportion of patients achieving complete remission off-therapy, compared with corticosteroid treatment alone, while decreasing treatment side-effects of corticosteroids. METHODS: We did a prospective, multicentre, parallel-group, open-label, randomised trial in 25 dermatology hospital departments in France (Ritux 3)...

For all visually competent organisms, the driving force behind the adaptation of photoreceptors involves obtaining the best balance of resolution to sensitivity in the prevailing light regime, as an increase in sensitivity often results in a decrease in resolution. A number of marine species have an additional problem to deal with, in that the juvenile stages live in relatively brightly lit shallow (100-200 m depth) waters, whereas the adult stages have daytime depths of more than 600 m, where little downwelling light remains...

INTRODUCTION: Non-tuberculous mycobacteria (NTM) can cause disease which can be clinically and radiologically undistinguishable from tuberculosis (TB), posing a diagnostic and therapeutic challenge in high TB settings. We aim to describe the prevalence of NTM isolation and its clinical characteristics in children from rural Mozambique. METHODS: This study was part of a community TB incidence study in children <3 years of age. Gastric aspirate and induced sputum sampling were performed in all presumptive TB cases and processed for smear testing using fluorochrome staining and LED Microscopy, liquid and solid culture, and molecular identification by GenoType® Mycobacterium CM/AS assays...

The monotypic Neotropical genus Claudiella Reichardt & Vanin, 1976 is currently known only from Brazil (C. ingens Reichardt & Vanin, 1976). We describe here three new species from Brazil, C. jefersoni sp. n., C. jeaneae sp. n. and C. anamariae sp. n., from Roraima, Minas Gerais and Bahia states, respectively, bringing to four the number of species included in Claudiella. These species can be distinguished by different characteristics observed in the legs, mouth parts, metathoracic wings and male genitalia.

Deletions and mutations affecting lymphoid transcription factor IKZF1 (IKAROS) are associated with an increased relapse risk and poor outcome in B-cell precursor acute lymphoblastic leukemia. However, additional genetic events may either enhance or negate the effects of IKZF1 deletions on prognosis. In a large discovery cohort of 533 childhood B-cell precursor acute lymphoblastic leukemia patients, we observed that single copy losses of BTG1 were significantly enriched in IKZF1-deleted B-cell precursor acute lymphoblastic leukemia (P=0...

The halogenated alkaloid chloromethylhalicyclamine B (1), together with the known natural compound halicyclamine B (2), was isolated from the extract of the sponge Acanthostrongylophora ingens. The structure of compound 1 was determined by spectroscopic means, and it was shown that 1 is produced by reaction of 2 with CH2Cl2 used for extraction. Compound 1 was a selective CK1δ/ε inhibitor with an IC50 of 6 μM, while the natural compound 2 was inactive. The absolute configuration of 1 was determined by quantum mechanical calculation of its ECD spectrum, and this also determined the previously unknown absolute configuration of the parent halicyclamine B (2)...

Changes in the chemical composition of plant defense compounds during herbivory can impact herbivore resource allocation patterns and thereby herbivore survival, growth, and immune response against endoparasitoid infection. Few studies have investigated folivore responses to changes in plant chemistry that occur under outbreak conditions in mature conifer systems. Using data from an earlier observational field study, we carried out laboratory bioassays to test how variation in monoterpenes in piñon pine trees (Pinus edulis, Pinaceae) during an outbreak affects growth, consumption, and immune response of a specialist herbivore, the Southwestern tiger moth (Lophocampa ingens, Arctiidae)...

Lung infections with Mycobacterium abscessus, a species of multidrug-resistant nontuberculous mycobacteria, are emerging as an important global threat to individuals with cystic fibrosis (CF), in whom M. abscessus accelerates inflammatory lung damage, leading to increased morbidity and mortality. Previously, M. abscessus was thought to be independently acquired by susceptible individuals from the environment. However, using whole-genome analysis of a global collection of clinical isolates, we show that the majority of M...

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare condition usually considered to have a favourable prognosis. However, it is not known whether polychemotherapy or immunosuppressive-based therapy is the best approach for treating SPTCL. Using data collected between 2000 and 2012 in France, we analysed clinical, biological and pathological data of 27 patients with SPTCL. Medical history revealed that 40% of patients had been previously diagnosed with an autoimmune disorder and 22% with inflammatory panniculitis...
