Improving outcomes for patients experiencing ischemic stroke requires faster recognition and appropriate intervention within the treatment window (the first 24 hours after symptom onset). This article discusses the pathophysiology underlying the various types of ischemic stroke; the risk factors for ischemic stroke; stroke presentation; and the evidence-based treatments, nursing assessments, and monitoring protocols that are critical to patient recovery.
Recent research has focused on the relationship between shame and psychopathology. It has been shown that shame predicts depressive and anxious symptoms, as well as substance abuse, non-suicidal self-injury, and aggression. Methylarginine acetate However, it remains unclear, how one emotion can influence psychiatric symptoms of such a broad spectrum. It is assumed that as shame is such an intense and painful emotion, it needs to be coped with and that the coping-strategies influence the effect shame has on psychopathologies. The Compass of Shame Scale (CoSS) is a questionnaire measuring 4 shame coping-strategies (withdrawal, avoidance, attacking others, and attacking the self) and the ability to adapt to shame.

In this article, a German version of the CoSS (CoSS-d) is validated in a community sample and is used to predict psychopathology in a clinical and non-clinical sample.

The CoSS-d shows a 4-factorial structure, good reliability, and validity and is stable over time. The 4 poles of shame-coping show an impact on depressive symptoms, aggression, and self-injury.

The CoSS serves as a reliable and unique measurement of trait shame-coping. Shame-coping styles are associated with psychopathology.

Previous studies have shown that the relationship between hypertension (HT) and contrast-associated acute kidney injury (CA-AKI) is not clear. We apply a systematic review and meta-analysis to assess the association between HT and CA-AKI.

We searched for articles on the study of risk factors for CA-AKI in the Embase, Medline, and Cochrane Database of Systematic Reviews (by March 25, 2021). Two authors independently performed quality assessment and extracted data such as the studies' clinical setting, the definition of CA-AKI, and the number of patients. The CA-AKI was defined as a serum creatinine (SCr) increase ≥25% or ≥0.5 mg/dL from baseline within 72 h. We used fixed or random models to pool adjusted OR (aOR) by STATA.

A total of 45 studies (2,830,338 patients) were identified, and the average incidence of CA-AKI was 6.48%. There was an increased risk of CA-AKI associated with HT (aOR 1.378, 95% CI 1.211-1.567, I2 = 67.9%). In CA-AKI with a SCr increase ≥50% or ≥0.3 mg/dL from baseline within 72 h, an increased risk of CA-AKI was associated with HT (aOR 1.414, 95% CI 1.152-1.736, I2 = 0%). In CA-AKI with a Scr increase ≥50% or ≥0.3 mg/dL from baseline within 7 days, HT increases the risk of CA-AKI (aOR 1.317, 95% CI 1.049-1.654, I2 = 51.5%).

Our meta-analysis confirmed that HT is an independent risk factor for CA-AKI and can be used to identify risk stratification. Physicians should pay more attention toward prevention and treatment of patients with HT in clinical practice.

The aim of this study was to investigate whether diagnostic ureteroscopy (URS) biopsy is unfavourable for bladder tumour recurrence in upper urinary tract urothelial carcinoma (UTUC).

We performed a retrospective analysis of 195 patients diagnosed with UTUC, who were divided into a diagnostic URS group (URS+) and a nondiagnostic URS group (URS-) according to whether diagnostic ureteroscopic biopsy was performed. A Cox regression model was used to analyse the risk factors for intravesical recurrence (IVR)-free survival (IRFS) and overall survival (OS) in UTUC after radical nephroureterectomy (RNU). Kaplan-Meier analysis was used to estimate the influence of factors on the incidence of IVR and the cumulative survival rate of UTUC.

Patients with a maximum tumour diameter of less than 3.1 cm, low-stage tumours, and ureteral tumours were more likely to undergo diagnostic URS before radical surgery. Multivariate Cox regression analysis showed that tumour pathological stage and diagnostic ureteroscopic biopsy can be used as predictors of IVR after RNU (p = 0.019, 0.033). Kaplan-Meier survival analysis found that diagnostic ureteroscopic biopsy was a high-risk factor for IRFS (p = 0.034). Subcomponent analysis showed that pTa/Tis/T1, pT2, pT3/pT4 stage, and diagnostic ureteroscopic biopsy with pTa/Tis/T1 stage were unfavourable for IVR (p = 0.047).

Diagnostic ureteroscopic biopsy before RNU should be carefully selected for patients with atypical preoperative UTUC. We believe that intravesical chemotherapy drug perfusion can be used after surgery to prevent IVR if biopsy is unavoidable, but this still requires further prospective studies.

Based on finite-element method, the phonon band structure and the transmission spectrum of the pentamode metamaterial are calculated, and then the pentamodal behavior of this structure is theoretically verified from two aspects, i.e. the physical properties and the mathematical definition. Results show that in the phonon band structure, there is a wider single-mode band gap, corresponding to the remarkable loss in the transmission spectrum. The ratio of bulk modulusBto shear modulusGis more than 300, which is obviously larger than that of traditional materials. Except for the isotropic bulk modulusB, the other mechanical moduli are all anisotropic. Five of six eigenvalues of elastic coefficient matrix are nearly zero for the microstructure, and only one is non-zero. These results demonstrate that this metamaterial microstructure performs excellent pentamodal characteristics, and also conforms to the mathematical definition of 'pentamode'.An unusually broad bell-shaped component (BSC) has been previously observed in surface electron diffraction on different types of 2D systems. It was suggested to be an indicator of uniformity of epitaxial graphene (Gr) and hexagonal boron nitride (hBN). In the current study we use low-energy electron microscopy and micro-diffraction to directly relate the BSC to the crystal quality of the diffracting 2D material. Specially designed lateral heterostructures were used to map the spatial evolution of the diffraction profile across different 2D materials, namely pure hBN, BCN alloy and pure Gr, where the alloy region exhibits deteriorated structural coherency. The presented results show that the BSC intensity has a minimum in the alloyed region, consequently showing that BSC is sensitive to the lateral domain size and homogeneity of the material under examination. This is further confirmed by the presence of a larger number of sharp moiré spots when the BSC is most pronounced in the pure hBN and Gr regions. Consequently, it is proposed that the BSC can be used as a diagnostic tool for determining the quality of the 2D materials.Estimation of joints' trajectories is commonly used in human gait analysis, and in the development of motion planners and high-level controllers for prosthetics, orthotics, exoskeletons and humanoids. Human locomotion is the result of the cooperation between leg joints and limbs. This suggests the existence of underlying relationships between them which lead to a harmonic gait. In this study we aimed to estimate knee and ankle trajectories using thigh and shank angles. To do so, an estimation approach was developed that continuously mapped the inputs to the outputs, which did not require switching rules, speed estimation, gait percent identification or look-up tables. The estimation algorithm was based on a nonlinear auto-regressive model with exogenous inputs. The method was then combined with wavelets theory, and then the two were used in a neural network. To evaluate the estimation performance, three scenarios were developed which used only one source of inputs (i.e., only shank angles or only thigh angles). First, knee angles $theta_k$ (outputs) were estimated using thigh angles $theta_th$ (inputs). Second, ankle angles $theta_a$ (outputs) were estimated using thigh angles $theta_sh$ (inputs), and third, the ankle angles were estimated using shank angles (inputs). The proposed approach was investigated for twenty-two subjects at different walking speeds and the leave-one-subject-out procedure was used for training and testing the estimation algorithm. Average RMS errors were 3.9$^circ$--5.3$^circ$ and 2.1$^circ$--2.3$^circ$ for knee and ankle angles, respectively. Average mean absolute errors MAEs were 3.2$^circ$--4$^circ$ and 1.7$^circ$--1.8$^circ$, and average correlation coefficients $rho_cc$ were 0.95 -- 0.98 and 0.94 -- 0.96 for knee and ankle angles, respectively. The limitations and strengths of the proposed approach are discussed in detail and the results are compared with several studies.In order to support bone tissue regeneration, porous biomaterial implants (scaffolds) must offer chemical and mechanical properties, besides favorable fluid transport. Titanium implants provide these requirements, and depending on their microstructural parameters, the osteointegration process can be stimulated. The pore structure of scaffolds plays an essential role in this process, guiding fluid transport for neo-bone regeneration. The objective of this work was to analyze geometric and morphologic parameters of the porous microstructure of implants and analyze their influences in the bone regeneration process, and then discuss which parameters are the most fundamental. Bone ingrowths into two different sorts of porous titanium implants were analyzed after 7, 14, 21, 28, and 35 incubation days in experimental animal models. Measurements were accomplished with x-ray microtomography image analysis from rabbit tibiae, applying a pore-network technique. Taking into account the most favorable pore sizes for neo-bone regeneration, a novel approach was employed to assess the influence of the pore structure on this process the analyses were carried out considering minimum pore and connection sizes. With this technique, pores and connections were analyzed separately and the influence of connectivity was deeply evaluated. This investigation showed a considerable influence of the size of connections on the permeability parameter and consequently on the neo-bone regeneration. The results indicate that the processing of porous scaffolds must be focused on deliver pore connections that stimulate the transport of fluids throughout the implant to be applied as a bone replacer.
