Heart failure is a highly prevalent chronic health problem associated with poor quality-of-life and negative outcomes. Self-care is a cornerstone in patients suffering from heart failure. Nurses are commonly engaged in enhancing patients' self-care behaviors, but the specific condition of deficit on self-care is not clearly identified by nurses. No nursing diagnoses focused on self-care of heart failure patients is currently available. PF-543 nmr This study aimed to develop a new nursing diagnosis that focuses on self-care in heart failure patients.

A concept and content analysis were used. Some steps of the concept analysis were performed through an integrative literature review conducted searching in PUBMED and CINAHL databases to identify attributes, antecedents, and consequences of the diagnosis. Forty-five articles were selected from the 1450 studies found. Then, the content analysis was performed by an international panel of 29 experts. Two Delphi rounds were used to achieve consensus and an item content validpected to assist nursing clinicians, educators, and students in clinical reasoning with the aim to improve diagnostic accuracy in identifying patients with a heart failure self-care deficit, to select the most appropriate interventions and pursue better outcomes.

Glioma is the most common type of primary brain tumor in adults, and it causes significant morbidity and mortality, especially in high-grade glioma (HGG) patients. The accurate prognostic prediction of HGG is vital and helpful for clinicians when developing therapeutic strategies. Therefore, we propose a machine learning-based survival prediction model by analyzing clinical and dose-volume histogram (DVH) parameters, to improve the performance of the risk model in HGG patients.

Eight clinical variables and 39 DVH parameters were extracted for each patient, who received radiotherapy for HGG with active follow-up. Ninety-five patients were randomly divided into training and testing cohorts, and we employed random survival forest (RSF), support vector machine (SVM), and Cox proportional hazards (CPHs) models to predict survival. Calibration plots, concordance indexes, and decision curve analyses were used to evaluate the calibration, discrimination, and clinical utility of these three models.

The RSF model showed the best performance among the three models, with concordance indexes of 0.824 and 0.847 in the training and testing sets, respectively, followed by the SVM (0.792/0.823) and CPH (0.821/0.811) models. Specifically, in the RSF model, we identified age, gross tumor volume (GTV), grade, Karnofsky performance status (KPS), isocitrate dehydrogenase (IDH), and D99 as important variables associated with survival. link2 The AUCs of the testing set were 92.4%, 87.7%, and 84.0% for 1-, 2-, and 3-year survival, respectively. According to this model, HGG patients can be divided into high- and low-risk groups.

The machine learning-based RSF model integrating both clinical and DVH variables is an improved and useful tool for predicting the survival of HGG patients.

However, current strategies address corrosion control from a global perspective for a whole component, without considering local adaptations to functionality specifications or inhomogeneous environments. Here, a novel concept is presented the local control and guidance of corrosion through a laser surface treatment. Immersion tests in saline solution of AZ31 magnesium alloy samples show degradation rates reduced up to 15 times with the treatment, owing to a fast passivation after the induced microstructural modifications. By controlling the treatment conditions, the degradation can be restricted to delimited regions and driven towards specific directions. The applicability of the method for the design of tailored degradation biomedical implants is demonstrated and uses for cathodic protection systems and batteries can also be anticipated.Photodynamic therapy is a new type of anti-tumor therapy with excellent therapeutic effects and minor side effects. The key factor for photodynamic therapy is highly efficient loading and protection of photosensitizers. Covalent organic framework is a new type of organic porous material with rich sources and has huge development potential in the loading of photosensitizers. However, the π-π interaction between the rigid monomers inevitably causes aggregation and quenching between photosensitizers, which in turn affects the rate of reactive oxygen production. Here, newly designed cationic flexible organic framework nanoparticles (PEI-Por NPs) are synthesized via one-step method with PEI25K and meso-tetra(p-formylphenyl)porphyrin under microwave irradiation. The structure of the flexible organic framework can effectively inhibit the aggregation and quenching of porphyrin. In addition, PEI-Por NPs had excellent gene transfection ability both in vitro and in vivo. link3 Excellent antitumor effect can be achieved by combining PEI-Por NPs' photodynamic therapy capacity and PEI-Por NPs-mediated PD-L1 gene silencing with the guidance of fluorescence imaging and photoacoustic imaging. This cationic flexible organic framework material combines the advantages of flexible building units and rigid monomers, which provides a basis for the development of nano-photosensitizers and excellent gene carriers, and has great potential for clinical application.As part of the European Union-funded project designated Paediatric Rare Tumours Network - European Registry (PARTNER), the European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT) is continuously developing consensus recommendations in order to harmonize standard care for very rare solid tumors of children and adolescents. This paper presents the internationally recognized recommendations for the diagnosis and treatment of sex cord stromal tumors (SCST). The clinical approach to sex cord stromal tumors of the testis (TSCST) and ovary (OSCST) depends on histological differentiation and tumor stage. Virtually all TSCSTs present as localized nonmetastatic tumors, with excellent prognosis after complete resection. In contrast, the prognosis of OSCSTs may be adversely affected by tumor spillage during surgery or presence of metastases. In these cases, cisplatin-based chemotherapy is recommended. Of note, some SCSTs may develop in the context of tumor predisposition syndromes, for example, DICER-1, so that specific follow-up is indicated. SCSTs should be diagnosed and treated according to standardized recommendations that include reference pathology, genetic testing for tumor predisposition syndromes in selected cases, and stratified adjuvant chemotherapy in patients with unfavorable risk profile. To ensure high quality of diagnosis and therapy, patients should be enrolled into prospective registries.Silkworm silk is a promising natural biopolymer for textile and biomedical applications for its remarkable flexibility, excellent biocompatibility and controllable biodegradability. The functionalization of silks makes them more versatile for flexible displays and visible bioscaffolds. However, fluorescent silks are normally fabricated through unstable physical absorption or complicated chemical reactions under harsh conditions. Herein, we developed a simple strategy for preparing fluorescent silks. Five aggregation-induced emission luminogens (AIEgens) with activated alkynes were synthesized by rational molecular design, and then reacted with silk fibers through facile metal-free click bioconjugation. The resulting conjugates show bright full-color emissions and high stability. A white light-emitting silk was fabricated by simultaneous bioconjugation with red-, green- and blue-emissive AIEgens. The red-emissive AIEgen-functionalized silks were successfully applied for long-term cell tracking and two-photon bioimaging, demonstrating great potential for tissue engineering and bioscaffold monitoring.

This study applied network analyses to illustrate patterns of associations between cancer-related physical and psychological symptoms (CPPS) and quality of life (QOL) before and after surgery.

Participants consisted of 256 gastric cancer patients admitted for curative section surgery at the surgical department in a teaching hospital in Korea between May 2016 and November 2017. Participants completed the survey, including MD Anderson Symptom Inventory, Hospital Anxiety and Depression Scale, and Functional Assessment of Cancer Therapy-Gastric Cancer before surgery (T0), 1 week after surgery (T1), and 3-6 months after surgery (T2).

Three networks featured several salient connections with varying magnitudes between CPPS and QOL across all time points. Particularly, anxiety was tightly connected to emotional wellbeing (EWB) across all time points and physical wellbeing (PWB) at T1. On the other hand, depression was connected to functional wellbeing at T0 and T2, gastric cancer concerns (CS) at T1, and PWB at T2. Distress and sadness were the most central symptoms in the three networks. Other central symptoms included shortness of breath at T0, fatigue at T0 and T1, and PWB and CS at T2. Anxiety, depression, and EWB served as bridges connecting CPPS to QOL across all time points with varying degrees of importance, as did PWB at T1 and T2.

Treating psychological distress and enhancing EWB and PWB can be high impact intervention targets throughout the cancer trajectory.

In the recent years, this liquid chromatography mode has been recognized as an important solution for the analysis of compounds not amenable to reverse phase chromatography. In this work, we evaluated three different hydrophilic liquid chromatography stationary phases for the determination of 14 highly polar anionic molecules including pesticides such as glyphosate, glufosinate, ethephon and fosetyl, their main metabolites, and bromide, chlorate, and perchlorate. Several mobile phase compositions were evaluated combined with different gradients for the chromatographic run. The two columns that presented the best results were used to assess the performance for the determination of the 14 compounds in challenging highly complex feed materials. Very different matrix effects were observed for most of the compounds in each column, suggesting that different interactions can occur. Using isotopically labeled internal standards, acceptable quantitative performance and identification could be achieved down to 0.02 mg kg-1 (the lowest level tested) for most compounds. While one column was found to be favorable in terms of scope (suited for all 14 compounds), the other one was more suited for quantification and identification at lower levels, however, not for all analytes tested.
