The median OS was 10.0 months. The 6-month, 1-year, and 2-year survival was 68.0%, 42.6%, and 17.0%, respectively. Cox regression analysis showed that patients receiving biopsy (P= 0.042) or chemotherapy (P= 0.029) had the better OS and these were regarded as independent prognostic factors. Further survival analysis showed that chemoradiotherapy had better survival benefit than other regimens.

In this study, we summarized the characteristics of patients with pineal GBM and showed the correlation between clinical characteristics and prognosis. This study may give readers a deep understanding of these rare GBMs and provide some references for future management.

Recurrent urinary tract infections (rUTIs) occur frequently after kidney transplantation (KT), however their optimal management remains undefined. This study aimed to identify risk factors for rUTI and to validate a protocol for UTI and rUTI treatment after KT.

This retrospective cohort study involved patients undergoing KT between January 2013 and July 2016. Patients were followed-up from day of KT until graft loss, death or end of follow-up (31 December 2018). We analysed all episodes of symptomatic UTI. The main outcome measure was rUTI after KT. Analysis was done per episode in a multilevel approach; patient features were considered in the distal level and UTI features in the proximal level. Univariate and multivariate analyses were performed by Cox regression. A propensity score was used to adjust the risk of patients with carbapenem-resistant Enterobacteriaceae.

During the study period, 787 patients underwent KT, of whom 152 (19.3%) developed 356 UTI episodes. selleck screening library The most common micro-organisms wereEscherichia coli (165/356; 46.3%) and Klebsiella pneumoniae (101/356; 28.4%). Multidrug-resistant micro-organisms were isolated in 161 UTIs (45.2%). Risk factors for rUTI were diabetic nephropathy as the cause of end-stage renal disease (P = 0.02), UTI in first 180 days after KT (P = 0.04), anatomic alteration of the urinary tract at UTI diagnosis (P = 0.004) and length of time to effective therapy (P = 0.002); UTI treatment duration according to institutional protocol (P = 0.04) was the only protective factor identified.

Appropriate therapy duration has an impact on rUTI prevention after KT.

Modulation of methylation pattern through mutations in ribosomal methyltransferases is a key mechanism of bacterial drug resistance. However, RsmG (GidB), which specifically methylates G527 in 16S rRNA, remains the only conserved methyltransferase known to be associated with low-level drug resistance in mycobacterial isolates. The mycobacterial RsmE homologue methylates U1498 in 16S rRNA in a highly specific manner. U1498 lies in the vicinity of the binding site for various aminoglycosides in the ribosome. However, the association of methylation at U1498 with altered drug response remains poorly understood.

A deletion mutant of the RsmE homologue in Mycobacterium smegmatis was generated by a suicidal vector strategy and drug susceptibility assays were performed on wild-type, knockout and complemented strains with varying concentrations of ribosomal- and non-ribosomal-targeting drugs.

Deletion of the RsmE homologue of M. smegmatis led to an at least two-fold increase in the minimum inhibitory concentrations (MICs) of aminoglycosides that bind in the decoding centre proximal to U1498 in the 30S subunit. The change in MICs was highly specific and reproducible and did not show any cross-resistance to other drug classes. Surprisingly, Rv2372c, the RsmE homologue of Mycobacterium tuberculosis, has the largest number of mutations among conserved ribosomal methyltransferases, after gidB, highlighting the role of mutations in RsmE methyltransferase as a key emerging mechanism of resistance in clinical strains.

We present the first evidence of an association of methylation of U1498 in 16S rRNA with development of low-level resistance in mycobacteria that must be tackled in a timely manner.

Implementation of cytarabine (araC) into induction and salvage regimen became standard of care for majority of MCL patients. In this study, tailored N-(2-hydroxypropyl)methacrylamide (HPMA)-based polymer nanotherapeutics containing covalently bound araC (araC co-polymers) were designed, synthesized and evaluated for their anti-lymphoma efficacy in vivo using a panel of six patient-derived lymphoma xenografts (PDX) derived from newly diagnosed and relapsed / refractory (R/R) MCL. While free araC led to temporary inhibition of growth of MCL tumors, araC co-polymers induced long-term disappearance of the engrafted lymphomas with no observed toxicity even in the case of PDX models derived from patients, who relapsed after high-dose araC-based treatments. The results provide sound preclinical rationale for the use of HPMA-based araC co-polymers in induction, salvage or palliative therapy of MCL patients.

Lower urinary tract symptoms (LUTSs), especially overactive bladder, are frequent in people with multiple sclerosis (PwMS). Urinary urgency and urge urinary incontinence could lead to precipitation and thus could increase the risk of falling in these individuals.

We aimed to assess the association between severity of LUTSs and risk of falling in PwMS.

PwMS with LUTSs were recruited in a neuro-urology department. Participants were asked about the number of falls in the past 3 months and their circumstances. Severity of LUTSs was assessed by the Urinary Symptoms Profile (USP) score, and individuals were classified as with or without urinary incontinence.

This cross-sectional study included 154 patients (69% women); the mean (SD) age was 50.1 (11.5) years and median EDSS was 5 (interquartile range 3-6). Overall, 20 (13%) patients reported one fall during the past 3 months, and 43 (28%) reported at least 2 falls. Only 9 (6%) patients reported a fall on the way to the toilet, 6 during a urinary urgency. No link was found between falls and urinary incontinence (P=0.
