3 (for PET) and 45 h (for PLA). A longer excretion period of PLA may be related to its potential to break down in the earthworms' digestive tract. This not only promotes the environmental degradation of PLA but also suggests the ecological risk caused by nanoparticles.

In February 2021, the Storting decided to abolish the mandatory medical certificate required for driving licence renewals for drivers over the age of 80. The decision will affect older drivers, traffic safety in general, and the everyday work of GPs in particular.

A content analysis was performed of the parliamentary debates and supporting documentation on the issue of medical certificates for older drivers, from the time of the motion in December 2020 up to the debate on when to implement the decision in May 2021.

The majority decision was founded on an anti-discrimination argument with undertones of district politics, in which the traffic safety element was relativised. A minority argued for a traffic safety policy based on a health authority decision and with an emphasis on the added overall health value. Cognitive screening tests were unanimously rejected.

The parties that represent the majority decision framed cognitive testing in a way that suggests the decision is a reaction to these tests rather than to the medical certificate requirement as such. There was little discussion on how the decision will affect GPs' ability to identify impaired fitness to drive among the older population.

De Winter's sign represents a constellation of ECG changes including upward sloping ST depressions greater than 1mm at the J-point, which end in tall, symmetrical T waves in the precordial leads and reciprocal ST elevation in aVR. The pattern is considered specific for acute occlusion of the LAD.

A previously healthy man in his forties was referred from urgent care with suspected non-ST-elevation myocardial infarction (NSTEMI) which presented with acute chest pain, ECG with ST depressions and positive troponin-T. Repeat ECG at the local hospital showed further changes, leading to echocardiogram which revealed pronounced cardiac hypokinesia both in the septum and apex. The patient was transferred to the closest interventional cardiology centre and underwent successful PCI. ECG findings were later interpreted as consistent with de Winter's sign.

This case illustrates the importance of recognising other ECG changes in addition to ST elevation as indicative of acute reperfusion therapy.

Augmented reality (AR) applied to surgical procedures refers to the superimposition of preoperative or intraoperative images into the operative field. Augmented reality has been increasingly used in myriad surgical specialties including urology. The following study reviews advance in the use of AR for improvements in urologic outcomes.

We identified all descriptive, validity, prospective randomized/nonrandomized trials and retrospective comparative/noncomparative studies about the use of AR in urology until March 2021. The Medline, Scopus, and Web of Science databases were used for literature search. We conducted the study selection according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Statement) Guidelines. We limited included studies to only those using AR, excluding all that used virtual reality technology.

A total of 60 studies were identified and included in the present analysis. Overall, 19 studies were descriptive/validity/phantom studies for specific AR methodologies, 4 studies were case reports, and 37 studies included clinical prospective/retrospective comparative studies.

Advances in AR have led to increasing registration accuracy as well as increased ability to identify anatomic landmarks and improve outcomes during urologic procedures such as RARP and robot-assisted partial nephrectomy.

The benefit of neoadjuvant systemic therapy (NAST) is not yet supported by randomized controlled trials in upper tract urothelial carcinoma (UTUC), but the evidence is increasing. This narrative systematic review was conducted to evaluate the available evidence on the role of NAST in patients undergoing radical nephroureterectomy (RNU) for UTUC.

We searched for all relevant articles or conference abstracts published and indexed in PubMed, Embase, and Scopus on July 19, 2021. The study was reported according to the PRISMA criteria and designed within the PICOS framework. We included studies comparing patients with non-metastatic UTUC who received neoadjuvant chemotherapy (NAC) or immunotherapy (NAI) with patients who underwent definitive surgery alone or surgery plus adjuvant systemic therapy. Prospective uncontrolled studies were also included.

We identified 27 reports (NAC, N.=24 and NAI, N.=3) published between 2010 and 2021. Twenty of the 24 studies on NAC were retrospective comparative analyses, wheand the inability to predict responsiveness and thereby pinpoint the optimal candidates remains a major challenge. There is a need to compare NAST to adjuvant therapies using clearly defined primary endpoints as minimum reporting standards developed by a multidisciplinary team.

Healthcare policies around the globe are aimed at achieving patient-centeredness. The patient is understood as a prosumer of healthcare, wherein healthcare service co-production and value co-creation take center stage. The article endeavors to unpack the state of the literature on the innovations promoting the transition toward patient-centeredness, informing policy and management interventions fostering the reconceptualization of the patient as a prosumer of healthcare services.

A hybrid review methodology consisting of a bibliometric-interpretive review following the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR-4-SLR) protocol is used. The bibliometric component enabled us to objectively map the extant scientific knowledge into research streams, whereas the interpretive component facilitated the critical analysis of research streams.

Patient-centeredness relies on a bundle of innovations that are enacted through a cycle of patients' activation, empowerment, involvement and engagement, wherein the omission of any steps arrests the transition toward service co-production and value co-creation. Institutional, organizational and cognitive barriers should be overcome to boost the transition of patients from consumers to prosumers in a patient-centered model of healthcare.

The article delivers the state of the art of the scientific literature in the field of innovations aimed at sustaining the transition toward patient-centeredness and provides some food for thoughts to scholars and practitioners who wish to push forward service co-production and value co-creation in healthcare.

Highly sensitive detection is crucial for all-optical photoacoustic (PA) imaging. However, free-space optical detectors are prone to optical aberrations, which can degrade the pressure sensitivity and result in deteriorated image quality. While spatial mode-filtering has been proposed to alleviate these problems in Fabry-Pérot-based pressure sensors, their real functional advantage has never been properly investigated.

We rigorously and quantitatively compare the performance of free-space and fiber-coupled detectors for Fabry-Pérot-based pressure sensors.

We develop and characterize a quantitative correlative setup capable of simultaneous PA imaging using a free space and a fiber-coupled detector.

We found that fiber-coupled detectors are superior in terms of both signal level and image quality in realistic all-optical PA tomography settings.

Our study has important practical implications in the field of PA imaging, as for most applications and implementations fiber-coupled detectors are relatively easy to employ since they do not require modifications to the core of the system but only to the peripherally located detector.

We show that FAPs from late-stage mdx mice exhibit aberrant HDAC activity and genome-wide alterations of histone acetylation that are not fully reversed by HDACi. In particular, combinatorial H3K27 and/or H3K9/14 hypo-acetylation at promoters of genes required for cell cycle activation and progression, as well as glycolysis, are associated with their downregulation in late-stage mdx FAPs. These alterations could not be reversed by HDACi, due to a general resistance to HDACi-induced H3K9/14 hyperacetylation. Conversely, H3K9/14 hyper-acetylation at promoters of Senescence Associated Secretory Phenotype (SASP) genes is associated with their upregulation in late-stage mdx FAPs; however, HDACi could reduce promoter acetylation and blunt SASP gene activation. These data reveal that during DMD progression FAPs develop disease-associated features reminiscent of cellular senescence, through epigenetically distinct and pharmacologically dissociable events. Wntagonist1 They also indicate that HDACi might retain anti-fibrotic effects at late stages of DMD.

The root of Tetrastigma hemsleyanum (RTH) has been widely used as a folk medicine in China. Meanwhile, its stems (STH) and leaves (LTH) are consumed as functional tea and food supplementation. Therefore, it is important to get a better understanding of the distribution of bioactive constituents in different parts of T. hemsleyanum.

To develop a method for quantitative analysis of multiple bioactive constituents and comparing their distribution in RTH, STH and LTH.

Ultra-performance liquid chromatography triple quadrupole ion trap tandem mass spectrometry (UPLC-QTRAP-MS/MS) was used for the quantitative analysis. The quantitative data were further analysed by principal component analysis (PCA), hierarchical cluster analysis (HCA) and partial least squares determinant analysis (PLS-DA).

Forty-two constituents in RTH, STH and LTH, including 14 flavonoids, three phenolic acids, 15 amino acids and 10 nucleosides, were quantitatively determined. The contents of flavonoids and phenolic acids in LTH were significantly higher than those in RTH and STH.
