Cephalosporin is the most commonly used empirical agent for urinary tract infection in children. However, increasing use of cephalosporins can lead to an increase in resistant pathogens. Therefore, this study aims to investigate the effects of monotherapy with ampicillin-sulbactam as an alternative to cephalosporins.

All 2- to 24-month-old patients who were hospitalized at Pusan National University Children's Hospital due to a first episode of febrile UTI during the 2-year period from 2012 to 2014 were included in the study. The subjects were divided into two groups according to their empirical therapy (cefotaxime or ampicillin-sulbactam). We determined the patients' UTI pathogens and their antibiotic susceptibilities and compared the effectiveness and the occurrence of adverse effects of ampicillin-sulbactam and cephalosporin therapy.

Forty-six patients were treated with cefotaxime (group A) and 41 patients with ampicillin-sulbactam as empirical antibiotic (group B). The most common pathogen in both groups was Escherichia coli, and antibiotic susceptibilities of the bacterial strains isolated from both groups were similar in ampicillin-sulbactam and cefotaxime . In addition, there was no significant difference in the duration of fever after treatment between the two groups (Group A 2.0 vs. Group B 3.0, P = 0.331). There were no treatment failures and no recurrence in either group, even in patients with resistant pathogens. The most common side effect of the antibiotic agents was diarrhea.

Ampicillin-sulbactam could be an effective alternative to cephalosporin as empiric antibiotic for the treatment of first-episode UTI in patients under 24 months of age.

It is important to investigate the behavior of protein hydrolysate components in both in vitro and in vivo studies, to support the elucidation of their biological functions. As protein hydrolysates and biological matrices are highly complex mixtures, it is essential to apply fully reliable and flexible analytical approaches.

A novel and generic Liquid Chromatography/Mass Spectrometry methodology was developed to analyze short peptides. #link# A stable-isotope-labeled labeling agent 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (

C

) was synthesized and used to prepare internal standards from non-labeled analyte peptides. The amino acid and peptides p, pG, Pp, GPp and PpG (where p stands for hydroxyproline) were used for proof of principle.

The method showed acceptable performance in solvent, in simulated gastrointestinal fluid and in serum. The (linear) dynamic range expanded to over four orders of magnitude, which is very useful when multiple analytes are analyzed in a biological matrix, due to the larg elucidation of the biological functions of protein hydrolysate components.Notch signaling plays a pivotal role in many cancers, including glioblastoma (GBM). Recombination signal binding protein for immunoglobulin kappa J region (RBPJ) is a key transcription factor of the Notch signaling pathway. Here, we interrogated the function of RBPJ in GBM. Firstly, RBPJ expression of GBM samples was examined. Then, we knocked down RBPJ expression in 2 GBM cell lines (U251 and T98) and 4 glioblastoma (GBM) stem-like cell lines derived from surgical samples of GBM (KGS01, KGS07, KGS10 and KGS15) to investigate the effect on cell proliferation, invasion, stemness, and tumor formation ability. Expression of possible downstream targets of RBPJ was also assessed. RBPJ was overexpressed in the GBM samples, downregulation of RBPJ reduced cell proliferation and the invasion ability of U251 and T98 cells and cell proliferation ability and stemness of glioblastoma stem-like cells (GSC) lines. These were accompanied by reduced IL-6 expression, reduced activation of STAT3, and inhibited proneural-mesenchymal transition (PMT). Tumor formation and PMT were also impaired by RBPJ knockdown in vivo. In conclusion, RBPJ promotes cell proliferation, invasion, stemness, and tumor initiation ability in GBM cells through enhanced activation of IL-6-STAT3 pathway and PMT, inhibition of RBPJ may constitute a prospective treatment for GBM.

Atopic dermatitis (AD) is driven by the interplay between a dysfunctional epidermal barrier and a skewed cutaneous immune dysregulation. As part of the complex skin barrier dysfunction, abnormalities in lipid organization and microbiome composition have been described. We set out to systematically investigate the composition of the stratum corneum lipidome, skin microbiome and skin physiology parameters at three different body sites in patients with AD and healthy volunteers.

We analysed tape strips from different body areas obtained from 10 adults with AD and 10 healthy volunteers matched for FLG mutation status for 361 skin lipid species using the Metabolon mass spectrometry platform. 16S rRNA data were available from all probands.

Our study showed that the lipid composition differs significantly between body sites and between AD patients and healthy individuals. Ceramide species NS was significantly higher in AD patients compared to healthy volunteers and was also higher in AD patients with a FLG mutation compared to AD patients without a FLG mutation. The correlation analysis of skin lipid alterations with the microbiome showed that Staphylococcus colonization in AD is positively correlated with ceramide subspecies AS, ADS, NS and NDS.

This is the first study to reveal site-specific lipid alterations and correlations with the skin microbiome in AD.

However, the precise mechanisms for this control are still not clear. To specifically investigate how leptin signalling on the NPY neurone contributes to the control of energy homeostasis, we generated an inducible adult-onset NPY neurone-specific leptin receptor (Lepr) knockout model and performed a comprehensive metabolic phenotyping study. Here, we show that the NPY neurone subpopulation that is directly responsive to leptin is not required for the inhibition of fasting-induced hyperphagia by leptin, although it is essential for the regulation of adiposity independent of changes in energy balance or diet composition. Furthermore, under obesogenic conditions such as a high-fat diet, a lack of Lepr signalling on NPY neurones results in significant increases in food intake and concomitant reductions in energy expenditure, leading to accelerated accumulation of fat mass. Collectively, these findings support the notion that Lepr-expressing NPY neurones act as the key relay point where peripheral adipose storage information is sensed, and corresponding responses are initiated to protect adipose reserves.

This study aims to evaluate the cost-effectiveness of using heat and moisture exchangers (HMEs) vs alternative stoma covers (ASCs) following laryngectomy in the United States.

DNA Damage inhibitor -effectiveness and budget impact analysis were conducted including uncertainty analyses using real-world survey data with pulmonary events and productivity loss.

HME use was more effective and less costly compared with ASCs. Quality-adjusted life years were slightly higher for HME-users. Total costs per patient (lifetime) were $59 362 (HME) and $102 416 (ASC). Pulmonary events and productivity loss occurred more frequently in the ASC-users. Annual budget savings were up to $40 183 593. Costs per pulmonary event averted were $3770.

HME utilization in laryngectomy patients was cost-effective. Reimbursement of HME devices is thus recommended. Utilities may be underestimated due to the generic utility instrument used and sample size. Therefore, we recommend development of a disease-specific utility tool to incorporate in future analyses.

Some studies have demonstrated a positive association of the rs7799039 genetic variant of the LEP gene with energy intake and metabolic parameters. The present study aimed to analyse the effects of the rs7799039 genetic variant of the LEP gene on metabolic parameters after weight loss secondary to a partial meal-replacement (pMR) hypocaloric diet.

We conducted a non-randomised, single-treatment study in 122 obese subjects with body mass index (BMI)>35kgm

. The subjects were treated with two intakes of a normocaloric hyperproteic formula during 12weeks. Anthropometric parameters and biochemical profile were measured at basal time and after 12weeks. The variant genetic variant (rs7799039) of the LEP gene was assessed by a real-time polymerase chain reaction.

We recruited 122 subjects [26 GG (21.3%), 59 GA (29.5%) and 37 AA (30.3%)]. link2 The mean (SD) age of the all group was 59.4(6.3)years (range 45-63years) and the mean (SD) BMI was 39.3(2.8)kgm

(range 36.2-45.1kgm

). After the pMR hypocaloric diet,t.

A multi-centre study to determine the outcomes and risks for invasive fungal disease (IFD) in myeloma (MM) patients treated with second-generation immunomodulatory drugs, proteasome inhibitors and monoclonal antibodies was conducted.

Clinical and microbiology records were reviewed to capture patient demographics, disease characteristics, treatment, IFD episodes and outcomes. Categorical and continuous variables between patients with IFD and without IFD were compared using chi-square test, Fisher's exact test and Mann-Whitney rank sum test, respectively, with P-value<.05 considered statistically significant.

Five out of 148 (3.4%) MM patients were diagnosed with five episodes of IFI 3 were proven, 1 probable and 1 possible. link3 Median time from commencement of new generation therapy to IFD diagnosis was 4.0months (Interquartile range [IQR] 3.4-5.7). In patients with IFD, median cumulative steroid dose over 60days was 1119mg (IQR 1066-1333mg). None of the patients with IFD had prolonged neutropenia (neutrophil count<0.5 × 10

/L for more than 10days). Common sites of infection were the respiratory tract (40.0%) and bloodstream (40.0%). Cryptococcus neoformans (n=2) and Candida krusei (n=1) were the fungal pathogens isolated in the three proven cases. 30-day mortality rate was 40.0%. Patients with IFD were younger (median 58 versus 68years, P=.52) and treated with more lines of therapy (median 5 vs 3, P=.04).

IFD rate is low in heavily treated MM patients treated with second-generation therapy including monoclonal antibodies. Patients do not appear to have traditional risk factors such as prolonged neutropenia.
