Consequently, the high photothermal energy of the PDA-Man appeared predominantly in the affected bacterialarea, while the overall environment remained at a low temperature. The fabricated nanoplatform showed excellent photothermal bactericidal effects, approximately 100% in a UTI model. Overall, this low-temperature photothermal nanoplatform provides an appropriate strategy for the elimination of bacteria in clinical applications. This article is protected by copyright.

Cigarette smoke is known to cause different forms of cancer and trigger the development of chronic diseases. In the last decade, electronic cigarettes have emerged as a healthier alternative associated to less harmful effects in comparison to traditional tobacco. However, the lack of standardization of electronic cigarettes products, makes it difficult to establish and compare the real effects on health of products from different manufacturers. To better understand the impact of smoking and vaping, the volatomic composition of urine samples from traditional tobacco smokers and electronic cigarette users was established and compared with non-smokers (control group), using headspace-SPME combined with GC-MS. A total of 45 urinary volatile organic metabolites belonging to different chemical families were identified in the urine of the studied groups. Benzene derivatives, terpenes, and aromatics were the chemical families that contributed the most to the urinary profile of smokers. The vapers urinary volatomic pattern was also dominated by terpenes and aromatics, in addition to alcohols. The orthogonal partial least squares-discriminant analysis of the data obtained indicated that the urinary profile of vapers is more closely related to the control group, reinforcing the hypothesis of the lowest harmfulness of electronic cigarettes. Further studies recruiting a higher number of subjects are therefore necessary to consolidate the data obtained. see more This article is protected by copyright. All rights reserved.

Port-wine stain (PWS) is a congenital capillary malformation that often occurs on the face. Feasible and quantitative evaluation of facial port-wine stain (FPWS) can significantly impact its clinical management and aid in future research.

To develop and validate an easy-to-use scoring system for FPWS evaluation.

A facial port-wine stain area and severity index (FSASI) scoring system was proposed. To determine the FSASI score, the face was divided into four regions forehead, right malar, left malar, and perioral. The severity of FPWS in each region was evaluated by three factors percentage of the area affected, lesion color, and thickness. To evaluate the intra- and inter-rater reliability of FSASI, two separate FSASI assessments on 111clinical pictures were conducted by each rater in a one-week interval, and the results from 6 independent raters at different time points were compared. Validity of the FSASI scores was assessed by comparing it with physician global assessment (PGA) and traditional classification data. Validity of the area and color elements of FSASI was also determined. The changes in FSASI scores after vascular-targeted photodynamic therapy (V-PDT) were analyzed to evaluate the treatment effect.

The FSASI scoring system showed good intra- and inter-rater reliability (ICC >0.75, p<0.001) and was found to be comparable to PGA scores (Spearman's r=0.752-0.907, p<0.001) and traditional classification data (Spearman's r=0.426-0.662, p<0.001). Efficacy analysis indicated that FSASI scores decreased after V-PDT treatment.

The results of this study demonstrated the reliability and validity of FSASI, which may be applied to assess the severity of FPWS and to evaluate treatment effects in clinical practice and research.

The results of this study demonstrated the reliability and validity of FSASI, which may be applied to assess the severity of FPWS and to evaluate treatment effects in clinical practice and research.

To evaluate the prognostic importance of concomitant non-regional lymph node (NRLN) and bone metastases in men with synchronous metastatic hormone-sensitive prostate cancer (mHSPC), determine whether M1b/M1c is the most appropriate M-stage and evaluate the additional importance to the distinction in low/high volume disease.

All men diagnosed with synchronous mHSPC from 2010-2018 in the Netherlands were identified in the Netherlands Cancer Registry (NCR). Men were categorized as having NRLN (M1a), bone (M1b), NRLN and bone (M1c), or visceral metastases (M1c). For men diagnosed since October 2015, disease volume could be determined. Analyses were performed in this cohort (>5.600 men), and repeated in the 2010-2018 cohort (>14.000 men). The Primary outcome measure in this observational cohort study was overall survival (OS) and cox regression was used to calculate hazard ratios (HR).

Compared to men with NRLN and bone metastases (reference group), OS of men with only NRLN (HR0.70, 95%CI0.55-0.88) wast NRLN and bone metastases as M1c or M1b is not appropriate. Adding a fourth M1-category to the ninth edition of the TNM classification should be contemplated. Furthermore, definitions of metastatic burden need to be re-evaluated.The Ki-67 proliferation index (PI) is a prognostic factor in neuroendocrine tumors (NETs) and defines tumor grade. Analysis of Ki-67 PI requires calculation of Ki-67-positive and Ki-67-negative tumor cells, which is highly subjective. To overcome this, we developed a deep learning-based Ki-67 PI algorithm (KAI) that objectively calculates Ki-67 PI. Our study material consisted of NETs divided into training (n = 39), testing (n = 124), and validation (n = 60) series. All slides were digitized and processed in the Aiforia® Create (Aiforia Technologies, Helsinki, Finland) platform. The ICC between the pathologists and the KAI was 0.89. In 46% of the tumors, the Ki-67 PIs calculated by the pathologists and the KAI were the same. In 12% of the tumors, the Ki-67 PI calculated by the KAI was 1% lower and in 42% of the tumors on average 3% higher. The DL-based Ki-67 PI algorithm yields results similar to human observers. While the algorithm cannot replace the pathologist, it can assist in the laborious Ki-67 PI assessment of NETs. In the future, this approach could be useful in, for example, multi-center clinical trials where objective estimation of Ki-67 PI is crucial.Primary hyperoxaluria type 1 (PH1) is associated with hepatic overproduction of oxalate. Kidneys gradually become unable to eliminate excess oxalate, leading to systemic oxalosis (SO) with deposits in organs.1 When kidney transplantation (KT) becomes necessary, this oxalate load can lead to oxalate nephropathy recurrence. We report the potential interest of 18-FluoroDeoxy-Glucose Positron Emission Computed Tomography (18-FDG-PET/CT) as a tool to assess SO in PH1 patients. Signed informed consent was obtained.Increasing rates of simultaneous heart-kidney (SHK) transplant in the United States exacerbate the overall shortage of deceased donor kidneys (DDK). Current allocation policy does not impose constraints on SHK eligibility, and how best to do so remains unknown. We apply a decision analytic model to evaluate options for heart transplant (HT) candidates with comorbid kidney dysfunction. We compare SHK with a "Safety Net" strategy, in which DDK transplant is performed six months after HT, only if native kidneys do not recover. We identify patient subsets for whom SHK using a DDK is efficient, considering the quality-adjusted life year (QALY) gains from DDKs instead allocated for kidney transplant-only. For an average-aged candidate with 50% probability of kidney recovery after HT-only, SHK produces 0.64 more QALYs than Safety Net at a cost of 0.58 more kidneys used. SHK is inefficient in this scenario, producing fewer QALYs per DDK used (1.1) than a DDK allocated for KT-only (2.2). SHK is preferred to Safety Net only for candidates with a lower probability of native kidney recovery (24 - 38%, varying by recipient age). This finding favors implementation of a Safety Net provision and should inform the establishment of objective criteria for SHK transplant eligibility.During recent years, a lot of interest has been focused on blood pressure in the context of pediatric anesthesia, trying to define what is normal in relation to age and what numeric values that should be regarded as hypotension, needing active intervention. However, blood pressure is mainly measured as a proxy for flow, that is, cardiac output. Thus, just focusing on specific blood pressure numbers may not necessarily be very useful or appropriate. The aim of this educational review is to put the issue of intraoperative blood pressure in the context of pediatric anesthesia in further perspective.This is the first report on the differences between adult primary herpetic oropharyngitis caused by the two types of the herpes simplex virus (HSV). Forty-one (25 type 1 and 16 type 2) HSV specific antigen positive cases among 68 immunoserologically confirmed adult primary HSV infection cases were investigated. A significantly low incidence of oral lesions and high incidence of nausea were seen in HSV type 2 oropharyngitis cases, which potentially indicates an association between the vagus nerve and HSV type 2 infection. Significantly increased white blood cell count and elevated C-reactive protein level were observed in HSV type 2 oropharyngitis cases. HSV type 2 possibly causes more severe symptoms and inflammatory reactions than HSV type 1.

Our primary objective was to describe the risk of major adverse cardiac events (MACE) at 1 month, 6 months and 12 months after a negative coronary CTA (cCTA), electrocardiogram (ECG) stress test, stress echocardiography, and myocardial perfusion scintigraphy (MPS) in low to intermediate-risk patients.

Initially, 952 articles were identified for screening, 81 met criteria for full-text review, and once risk of bias was assessed, 33 articles were included in this meta-analysis. We utilized a random-effects model to assess pooled MACE event proportion for patients undergoing evaluation of ACS when risk stratified to a low to intermediate-risk category after undergoing standard testing. Heterogeneity analysis was performed using Cochrane's Q test and I2 statistic.

Twenty-one studies evaluated follow up at 1 month with cCTA having a 0.09% (95CI 0.03% - 0.26%) pooled MACE compared to 0.23% (95CI 0.01% - 5.8%) of the exercise stress testing(p=1). MPS and cCTA had an overall event rate of 0.15% (95CI 0.06%-0.41, can be discharged without any further risk stratification if their ECG and troponin are reassuring given low MACE.As effects of climate change intensify, there is a growing need to understand the thermal properties of landscapes and their influence on wildlife. A key thermal property of landscapes is vegetation structure and composition. Management approaches can alter vegetation and consequently the thermal landscape, potentially resulting in underappreciated consequences for wildlife thermoregulation. Consideration of spatial scale can clarify how management overlaid onto existing vegetation patterns affects thermal properties of landscapes relevant to wildlife. We examined effects of temperature, fire management, and vegetation structure on multi-scale habitat selection of an ectothermic vertebrate (the turtle Terrapene carolina triunguis) in the Great Plains of the central United States by linking time-since-fire data from 18 experimental burn plots to turtle telemetry locations and thermal and vegetation height data. Within three 60-ha experimental landscapes, each containing six 10-ha sub-blocks that are periodically burned, we found that turtles select time-since-fire gradients differently depending on maximum daily ambient temperature.
