Research is needed to identify specific family and patient characteristics that facilitate weight gain and to develop corresponding interventions to improve outcome. © 2020 Wiley Periodicals, Inc.BACKGROUND AND AIM Over the past years, three-dimensional (3D) models of patient-specific anatomical conditions are being used to improve the comprehension and surgical management of a variety of diseases. It is an additional diagnostic tool that aids clinical decision-making. Furthermore, this technology is still not routinely used in the medical field since its availability is limited by cost and complex process. METHODS AND RESULTS We describe a patient with a balanced-type double aortic arch encircling trachea and esophagus. Considering the clinical symptoms, surgical decompression of these structures and defined aortic arch reconstruction was indicated. The 3D printed model revealed narrowing of the left aortic arch at the junction of the descending thoracic aorta that did not clearly appear on the conventional images reconstruction. The left aortic arch was divided and the symptoms completely disappeared. No immediate or late complications occurred. CONCLUSION 3D printed models can be helpful in surgical planning of congenital heart malformations. It should be strongly considered as an additional tool in complex cases. © 2020 Wiley Periodicals, Inc.Metallophilic macrophages (MMs) are a distinct cell type of the rodent thymus. Our previous research has focused on the morphological characteristics of MMs, as well as on the molecular mechanisms involved in the development and tissue positioning of these cells. However, the postnatal development of MMs has not been sufficiently studied. In the present study, we investigated the positioning of MMs in the rat thymus between postnatal day 0 (P0) and P30. On P0, MMs were evenly distributed all over the thymic tissue-that is, the cortex, cortico-medullary zone and medulla. From P0 to P15, the number of MMs in the thymic cortex significantly decreased, and after P15, this number did not change. Thus, the present study shows that on P15, MMs almost completely disappear from the thymic cortex and show their adult position in the cortico-medullary zone and in the medulla. © 2020 Blackwell Verlag GmbH.Microbially derived surfactants, so-called biosurfactants, have attracted significant attention as an environmentally friendly alternative to their chemically synthesized counterparts. Particularly, rhamnolipids offer a large potential with their outstanding surfactant properties such as complete biodegradability, low toxicity, and stability. Rhamnolipids are naturally synthesized by the opportunistic human pathogen Pseudomonas aeruginosa under the tight regulation of a highly complex quorum-sensing system. The heterologous production of mono-rhamnolipids by a newly isolated nonpathogenic strain of the genus Pantoea was investigated. Analysis of the genome obtained by a chimeric assembly of Nanopore long reads and high-quality Illumina reads suggested that the strain has evolved to an epiphytic rather than a pathogenic lifestyle. Functional heterologous expression of the mono-rhamnolipid operon rhlAB derived from a P. aeruginosa strain was established and confirmed by HPLC analysis. Transcriptome analysis indicated destabilizing effects of the produced rhamnolipids on the cell envelope of the host resulting in the induction of molecular stress responses. After integration of the rmlBCDA operon, extracellular rhamnolipids in amounts up to 0.4 g/L could be detected and were identified as a mono-rhamnolipid Rha-C10 -C10 by MALDI-TOF mass spectrometry. © 2020 The Authors. MicrobiologyOpen published by John Wiley & Sons Ltd.Per- and poly-fluoroalkyl substances (PFAS) are a broad class of environmentally persistent chemicals that include thousands of potentially toxic synthetic organic molecules. Some PFAS have been shown to cause adverse health effects including decreased total cholesterol, birth weight, and reproductive success in laboratory animals; however, a lack of chronic toxicity data exists for PFAS in avian ecological receptors. The present study reports the chronic toxicity of perfluorooctane sulfonic acid (PFOS) and a mixture of PFOS and perfluorohexane sulfonic acid (PFHxS) to Northern Bobwhite quail (Colinus virginianus) via oral exposure from drinking water. Female weight gain was significantly adversely affected at an average daily intake (ADI) of 3.10x10-3 ± 0.15x10-3 mg PFOSPFHxS (1.21) mixture x kg-1 body weight x day-1 . Successful liberation from shell once pipped was significantly adversely affected at an ADI of 2.45x10-3 ± 0.01x10-3 mg PFOS x kg-1 body weight x day-1 . These values are comparatively much lower than the current dietary avian toxicity reference value (TRV) where birds were exposed via the feed suggesting the need for updated avian TRVs. Relationships between test chemical (PFOS) and test substance (PFOSPFHxS) showed that PFOS and PFHxS have possible interacting effects in avian receptors and likely differing mechanisms of toxicity depending on chemical co-occurrence and dose. see more Both the single chemical and mixture exposures produced similar and possibly additive toxicity values.

However, this device has never been studied in people with bronchiectasis. Hence, the objective of this study was to compare the effect of bubble-PEP device, the active cycle of breathing technique (ACBT) and no intervention (control) on sputum clearance in people with bronchiectasis. METHODS This was a prospective, randomised cross-over trial with concealed allocation, assessor blinding and intention-to-treat analysis. Adult participants with stable bronchiectasis and productive of sputum daily were recruited. Participants performed 30-min of bubble-PEP, ACBT or control in random order whilst sitting, followed by 60-min of quiet sitting, on three separate days at the same time within a 10-day period. Primary outcome measure was wet weight of expectorated sputum during 30-min intervention, 60-min post intervention and total wet weight (30 min plus 60 min). RESULTS Thirty-five-participants (11 males, mean [standard deviation] age 75 [8] years, forced expiratory volume in 1 s 72 [20] % predicted) were recruited and 34 completed the study. There was no significant difference in sputum wet weight between bubble-PEP and ACBT during 30-min intervention (mean difference [95% confidence interval]) -0.59 g [-1.37, 0.19] and total wet weight (0.74 g [-0.54, 2.02]). Sputum wet weight was significantly greater in bubble-PEP than ACBT at 60-min post intervention (1.33 g [0.19, 2.47]). CONCLUSION Sputum wet weight was significantly greater with bubble-PEP than control at all time periods, and greater than ACBT at 60-min-post. Bubble-PEP could be considered an alternative sputum clearance technique to ACBT. © 2020 John Wiley & Sons, Ltd.The marine sulfur cycle is substantially fueled by the phytoplankton osmolyte dimethylsulfoniopropionate (DMSP). This metabolite can be metabolized by bacteria, which results in the emission of the volatile sulfur species methanethiol (MeSH) and the climate-cooling dimethylsulfide (DMS). It is generally accepted that bacteria contribute significantly to DMSP turnover. We show that the other low molecular weight zwitterionic dimethylsulfonio compounds dimethylsulfonioacetate (DMSA) and gonyol are also widely distributed in phytoplankton and can serve as alternative substrates for volatile production. DMSA was found in 11 of the 16 surveyed phytoplankton species, and gonyol was detected in all haptophytes and dinoflagellates. These prevalent zwitterions are also metabolized by marine bacteria. The patterns of bacterial MeSH and DMS release were dependent on the zwitterions present. Certain bacteria metabolize DMSA and gonyol and release MeSH, in others gonyol inhibited DMS-producing enzymes. If added in addition to DMSP, gonyol entirely inhibited the formation of volatiles in Ruegeria pomeroyi. In contrast, no substantial effect of this compound was observed in the DMSP metabolism of Halomonas sp. We argue that the production of DMSA and gonyol and their inhibitory properties on the release of volatiles from DMSP has the potential to modulate planktonic sulfur cycling between species. © 2020 The Authors. MicrobiologyOpen published by John Wiley & Sons Ltd.A bleached kraft pulp mill discharging effluent to the Mattagami River in northern Ontario, Canada, closed after almost 90 years of operation. During its operation, effluent from the mill influenced biota in the downstream areas. To assess shifts in the reliance of biota from mill-derived nutrients, the isotopic composition (δ13 C and δ15 N) of white sucker (Catostomus commersoni) muscle and whole mayflies (Hexagenia sp.) were compared before (1990s) and after the pulp mill's closure (2012-2014). To better understand other potential sources of spatial and temporal change, samples from three other tributaries in the basin with dams, ongoing pulp mill operations, sites receiving sewage, and at several reference sites were collected and compared. Irrespective of time period, biota collected at sites downstream of both dams and active pulp mills tended to have elevated δ13 C values, but variable changes in δ15 N (negligible in most cases) when compared to upstream samples. The isotopic composition of mayflies varied at reference sites over time, with decreasing values of δ13 C and δ15 N (mayflies only) with increasing depth, and there was evidence of lower δ13 C in fish after the pulp mill closure. Overall, these results suggest the importance of long-term, regional-scale measurements for documenting the effects of stressors on nutrient use by aquatic species.

There has been a rise in resistant urinary tract infections (UTIs) which is the most common infection in pregnancy. This can be challenging in pregnancy due to the additional need to safeguard foetal development. The study's aim was to explore views about AMR in women who experienced UTIs in pregnancy. DESIGN Fifteen semi-structured interviews were conducted in the UK and analysed using thematic analysis. RESULTS Results highlighted two themes conceptualization of AMR and pregnancy as a deviation from the norm, with an overarching theme of 'self-efficacy'. Results show that participants were concerned about AMR but uncertain about the effect on society compared to individual's taking antibiotics and about completing antibiotic courses. Participants reported an unsparing use of antibiotics was justified in pregnancy, and behaviours like drinking adequate water were ineffective at preventing UTIs. In summary, women had low self-efficacy regards tackling AMR and managing their health. CONCLUSION Misconceptions about how AMR affects society vs the individual translated into viewing it as a future problem to be tackled by the health-care sector. Consequently, AMR requires reconceptualization as a current problem requiring collective action. This research also indicates women endorse a biomedical model of UTIs in pregnancy which attributes resolving illness to interventions such as medicines, implying an automatic reliance on antibiotics. Subsequently, there is a need for self-efficacy by focusing on a behavioural model which emphasizes behaviours for infection prevention, thus reducing the need for antibiotics. © 2020 The Authors Health Expectations published by John Wiley & Sons Ltd.
