    Liquid biopsies offer a less invasive alternative to tissue biopsies for diagnosis, prognosis, and determining therapeutic potential in renal cell carcinoma (RCC). Unfortunately, clinical studies using liquid biopsy biomarkers in RCC are limited. Accordingly, we examine RCC biomarkers, derived from urine, plasma, serum and feces of potential impact and clinical outcome in these patients. A PRISMA checklist was used to identify valuable liquid biopsy biomarkers for diagnosis (plasma cfDNA, serum- or urine-derived circulating RNAs, exosomes and proteins), prognosis (plasma cfDNA, plasma- or serum-derived RNAs, and proteins), and therapeutic response (plasma- and serum-derived proteins). Although other analytes have been identified, their application for routine clinical use remains unclear. In general, panels appear more effective than single biomarkers. Important considerations included proof of reproducibility. Unfortunately, many of the examined studies were insufficiently large and lacked multi-center rigor. Cost-effectiveness was also not available. Accordingly, it is clear that more standardized protocols need to be developed before liquid biopsies can be successfully integrated into clinical practice in RCC.

    This study investigated the effect of different reheating treatments on gel properties and flavor changes of surimi products. As the reheating temperature increased from 90 °C to 121 °C, the heat-induced proteolysis produced more abundant umami and sweet amino acids, which took part in the conversion of IMP to AMP, thus enhancing the taste profiles. Reheating increased the exposure of active -NH2 terminals in proteins, which boosted Maillard and Strecker reactions with carbonyl compounds originated from fatty acid oxidation, thus not only reducing the aldehydes and esters contents but also lowering the whiteness of surimi products. Reheating at 90 °C prohibited the production of warmed-over flavor (WOF) and well-preserved the textural characteristics, but high temperatures ≥100 °C were prone to generate furan as the major WOF substance and to destroy gel structures. Collectively, this study provides new insights on understanding the role of reheating on sensory properties of surimi products.

    Cyclolinopeptides (CLs) have anti-inflammatory, anti-osteoporosis, and anti-tumor effects, however, low water and oil solubility greatly limit their application. Herein, CLs-loaded β-cyclodextrin (β-CD) emulsions were prepared with different oil phases. The in vitro digestibility, cellular absorption, and anti-inflammatory effects were evaluated. Camellia oil diacylglycerol (CO DAG) showed enhanced dissolving ability for CLs due to high polarity. β-CD formed inclusion complexes with DAG through hydrogen bond and the emulsions showed smaller size and higher physical stability with 50 % (w/w) oil. The in vitro digestibility of the DAG emulsion was increased and the CLs' bioavailability was 13.6-fold higher than CLs in oil. The CLs-loaded Pickering emulsion digesta exhibited a higher nitric oxides (NO) inhibition rate (58.62 %) and Caco-2 cell penetration (3.09 × 10-6 cm/s). Therefore, emulsion formulated with β-cyclodextrin and DAG can effectively improve the solubility and bioavailability of CLs, which has significant potential for application in functional foods and pharmaceutical industry.

    OBJECTIVE: To determine the mediating role of family cohesion in the relationship between death anxiety and readiness toward advance care planning (ACP).

    METHODS: This study included 965 Chinese community-dwelling older adults. Pearson correlation coefficient was conducted to assess the relationship between readiness toward ACP, death anxiety, and family cohesion. Structural equation model was used to examine the study hypothetical model.

    RESULTS: 965 valid questionnaires were collected. Death anxiety is significantly related to the readiness toward ACP (r = -0.437, P < 0.01) and family cohesion (r = -0.444, P < 0.01), and family cohesion exhibited a positive correlation with readiness toward ACP (r = 0.499, P < 0.01). Family cohesion partially mediated the effect of death anxiety on readiness toward ACP, accounting for 35.94 % of the total effect.

    CONCLUSIONS: Family cohesion mediates the relationship between death anxiety and readiness toward ACP. Healthcare professionals should implement measures to alleviate death anxiety and promote family cohesion in older adults, thereby enhancing their readiness toward ACP.

    Ionic liquids (ILs) have emerged as more desirable liquids than conventional solvents for chemistry, material science, engineering and environmental science. The scientific literature reveals an exponential increase in the number of research projects aimed at exploring the chromatographic features of ionic liquids. The review provides sound scientific data to examine the structural characteristics of ionic liquids that make them ideal for use in chromatography. This contribution is distinctive since it integrates the synthesis, benefits, drawbacks, and possible uses of ionic liquids in several chromatographic separation processes. Keeping the cation the same, the introduction of different anions is also possible, and this strategy leads to the synthesis of a series of different ionic liquids with varying properties. A detailed probe is given on the influence of ionic liquid structure and properties on their chromatographic behavior, both as stationary phase and mobile phase and/or mobile phase additives. Ionic liquid based immobilized stationary phases and their analyte retention mechanisms (hydrogen bonding, electrostatic forces of attraction, π-π stacking, ion exchange, and hydrophilic interactions, etc.) are critically discussed. Finally, a thorough analysis of the literature suggests that IL-based stationary phases may undergo multi-mode and more flexible retention mechanisms. Their dual polarity can facilitate interaction with both polar and non-polar compounds. Similarly, using IL as a mobile phase can offer more pragmatic and sustainable options for enantiomer separation.

    BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by dysregulated immune responses and inflammation. Interleukin-37 (IL-37) is a recently discovered immunomodulatory cytokine with potential anti-inflammatory properties. This systematic review explores the relationship between IL and 37 and SLE disease activity, and evaluates its potential as a therapeutic agent.

    METHODS: Electronic databases were searched for studies investigating IL-37 and SLE. Data on IL-37 levels, SLE Disease Activity Index (SLEDAI) score, genetic polymorphisms, and its therapeutic effects from pre-clinical studies were extracted.

    RESULTS: Previous studies presented conflicting findings on IL-37 levels in SLE patients. Some reported positive correlations with disease activity, while others observed associations between lower IL-37 and increased activity. Genetic variations in the IL-37 gene linked to SLE susceptibility have been reported. Pre-clinical studies using engineered mesenchymal stem cells or direct IL-37 treatment showed promise in reducing disease severity in mouse models and cell cultures of SLE. The analysis of multiple studies reveals that IL-37 expression varies significantly across different SLE subtypes.

    CONCLUSIONS: While a potential link exists between IL and 37 and disease activity, genetic predisposition, and therapeutic benefit, further research is needed. Future studies with standardized designs, larger and more diverse populations, and mechanistic investigations are crucial to determine the therapeutic potential of IL-37 for SLE. This review highlights the need for well-designed clinical trials to evaluate the safety and efficacy of IL-37 therapy in patients with SLE.

    Aloe vera is commonly used as traditional medicine for cutaneous wound healing. Nonetheless, the wound healing mechanisms of Aloe vera remain unclear. This review aims to provide insight into the molecular mechanisms of Aloe vera in promoting cutaneous wound healing, with particular emphasis on the mechanisms that stimulate cell proliferation and migration. Aloe vera has been shown to upregulate growth factors such as keratinocyte growth factor-1 (KGF-1), transforming growth factor-β (TGF-β), cyclin D1, insulin-like growth factor 1 (IGF-1), vascular endothelial growth factor (VEGF), basic fibroblastic growth factor (bFGF), and microfibril-associated glycoprotein 4 (MFAP4), as well as collagen, fibrillin, elastin, α-smooth muscle actin (α-SMA), integrins, and platelet endothelial cell adhesion molecule 1 (PECAM-1, also known as CD31), while downregulating the expression of matrix metalloproteinases (MMPs). In addition, Aloe vera was also found to upregulate PI3K/Akt and MAPK pathways, as well as the TGF-β signalling pathway via Smad proteins. Furthermore, molecular docking studies revealed that certain chemical constituents of Aloe vera bind to some of the forementioned growth factors or signalling molecules. With regards to current applications, although human clinical trials have reported positive results from using Aloe vera in healing open wounds and burns and alleviating some inflammatory skin diseases, the current commercial uses of Aloe vera remain largely focused on cosmetic products. Thus, greater advances are required to promote the use of Aloe vera products in clinical settings.

    Point-of-care ultrasound (POCUS) bridges diagnostic gaps across the continuum of care worldwide and is a particularly potent tool in resource-limited settings (RLS). To capture the scope of its current impact in RLS, this narrative review of POCUS use in public health, primary care, outpatient specialty, pre-hospital, and palliative care settings discusses its use in reducing diagnostic health care inequities. Disease-specific protocols, longitudinal training, quality assurance, and task shifting are key to robust expansion of POCUS in RLS.

    PURPOSE: Appendicular skeleton markers are commonly used for maturity assessment for Adolescent Idiopathic Scoliosis (AIS) patients. Traditionally, Risser has been a standard skeletal maturity assessment method. More recently, Sanders classification (SSMS), as a more comprehensive system, became popular, especially in decision-making for Vertebral Body Tethering (VBT). Thumb-Ossification Composite Index (TOCI), using ossification of thumb epiphyses, has been claimed to more accurately stage patients around their peak height velocity. However, growth peaks may occur separately at lower limbs and trunk. Hence, Cervical Vertebral Maturity (CVM), using cervical spine morphology, possesses a potential to better estimate spinal growth as it uses axial skeleton markers instead of appendicular skeleton markers. The aim of the study was to compare various axial and appendicular skeletal maturity assessment methods for longitudinal growth and curve modulation after VBT.

    METHODS: A retrospective analysis of prospectively collected data was conducted. Skeletal maturity was determined using Risser, SSMS, TOCI and CVM for each patient. Crosstabulations of axial vs. appendicular markers were formed to analyze their concordance and discordance. Logistic and logarithmic regression models were run to assess longitudinal growth (postoperative height gain and leg-length growth) and curve modulation (follow-up instrumented Cobb correction after index operation), respectively. Models were compared using Akaike information criterion (AIC).

    RESULTS: 34 patients (32 F/2 M, mean age: 12.8 ± 1.5 years, mean follow-up: 47.7 (24-80) months) were included. The median preoperative maturity stages were: Risser: 1 (-1-4), SSMS: 4 (1-7), TOCI: 6 (1-8) and CVM: 4 (1-6). At latest follow-up, all patients reached skeletal maturity. Concordance and discordance were observed between axial vs. appendicular systems that demonstrated a range of possible distributions of CVM, where trunk peak height velocity occurred before, simultaneously with or after the standing height peak height velocity. R-squared values for Risser, SSMS, TOCI and CVM were 0.701, 0.783, 0.810 and 0.811, respectively, for prediction of final height; 0.759, 0.821, 0.831 and 0.775 for final leg-length, and 0.507, 0.588, 0.668 and 0.673 for curve modulation. Delta AIC values demonstrated that different skeletal maturity assessment methods provided distinctive information regarding follow-up height gain, leg-length growth and curve behavior.

    CONCLUSIONS: Risser score provided considerably less information for all three outcome variables. TOCI and SSMS provided substantial information regarding remaining leg-length assessments, while in terms of assessment of total height gain and curve modulation after surgery, CVM and TOCI offered substantial information and SSMS offered strong information. Mutual use of axial and appendicular markers may provide valuable insight concerning timing of surgery and magnitude of surgical correction.

    INTRODUCTION: The evolving landscape of general practice (GP)/family medicine (FM) in the post-COVID-19 era, focussing on integrating telemedicine and remote consultations requires a new definition for this specialty. Hence, a broader consensus-based definition of post-COVID-19 GP/FM is warranted.

    METHODS: This study involved a modified electronic Delphi technique involving 27 specialists working in primary care recruited via convenient and snowball sampling. The Delphi survey was conducted online between August 2022 and April 2023, utilizing the Google Forms platform. Descriptive statistics were employed to analyse consensus across Delphi rounds.

    RESULTS: Twenty-six international experts participated in the survey. The retention rate through the second and third Delphi rounds was 96.2% (n = 25). The broader consensus definition emphasizes person-centred care, collaborative patient-physician partnerships, and a holistic approach to health, including managing acute and chronic conditions through in-person or remote access based on patient preferences, medical needs, and local health system organization.

    CONCLUSION: The study highlights the importance of continuity of care, prevention, and coordination with other healthcare professionals as core values of primary care. It also reflects the role of GP/FM in addressing new challenges post-pandemic, such as healthcare delivery beyond standard face-to-face care (e.g. remote consultations) and an increasingly important role in the prevention of infectious diseases. This underscores the need for ongoing research and patient involvement to continually refine and improve primary healthcare delivery in response to changing healthcare landscapes.

    OBJECTIVE: Our study aimed to assess the heart failure/cardiomyopathy-related population-level mortality trends among patients with obesity in the United States and disparities across demographics.

    METHODS: We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database among adults aged ≥25 from 1999 to 2019. Heart failure/cardiomyopathy were listed as the main causes of death, with obesity as a contributing cause. We calculated age-adjusted mortality rates (AAMR) per 100,000 individuals and estimated the average annual percent change (AAPC). We also evaluated the social vulnerability of United States counties (2014-2018).

    RESULTS: There were 29,334 deaths related to heart failure/cardiomyopathy among patients with comorbid obesity. The overall AAMR increased from 0.41 in 1999 to 0.94 in 2019, with an AAPC of 3.78 (95 % CI, 3.41-4.14). The crude mortality rate increase for heart failure/cardiomyopathy was greater in individuals with comorbid obesity than in those without. Males had a higher AAMR than females (0.78 vs 0.55). African Americans also had higher AAMR than Whites (1.35 vs 0.62). The AAMR was higher in rural areas than in urban regions (0.76 vs 0.66). The overall AAMR was higher in counties with social vulnerability index-Quartile 4 (SVI-Q4) (most vulnerable) (1.08) compared to SVI-Q1 (least vulnerable) (0.63) with a risk ratio of 1.71 (95 % CI: 1.61-1.83).

    CONCLUSION: Heart failure/cardiomyopathy mortality in individuals with comorbid obesity was rising. Males, African Americans, and individuals from rural regions had higher AAMR than their counterparts.

    Non-toxic, biocompatible, biodegradable, and bioadhesive, characteristics, of natural polysaccharides, are widely recognized and well accepted. Their usage in dietary, medicinal, biomedical, and cosmetic, applications is due to their unique and fascinating attributes. Xanthan gum, a microbial polysaccharide possesses diverse-wonderful features. It is a naturally occurring heteropolysaccharide, with large molecular weight, derived from the Gram-negative bacteria, Xanthomonas Campestris. This biopolymer has been studied extensively as a matrix for tablets, nanoparticles, microparticles, hydrogels, and various other formulation types. However, indigenous xanthan gum has its own set of restrictions, which may be overcome by chemical modification, to fine-tune the characteristics of the native gum, for attaining unmet demands. This approach has huge potential in the drug delivery and numerous other promising applications. The objective of this review is to provide a consolidated source of information on xanthan gum-based gastroretentive systems. Several approaches of floating techniques, with recent research avenues and patents, utilizing the natural polysaccharide xanthan gum is also discussed.

    This study investigates the preliminary efficacy of drug encapsulation in chitosan hydrogels by cathodic electrodeposition for the encapsulation of the aromatic dye methyl orange to enhance drug delivery in biological systems. Chitosan, a biocompatible and transparent polymer, is known for its ability to effectively encapsulate and transport therapeutic agents, which is critical for sustained and targeted drug release. Methyl orange was selected as a model drug to study the effects of deposition and immersion times on encapsulation efficiency. The effects of deposition and immersion times on encapsulation efficiency were analyzed by synthesizing multilayer hydrogels via electrochemical oxidation. Characterization techniques, including UV-visible spectroscopy, FTIR, and NMR, were employed; FTIR indicated an effective absorption of 4.34 % for Td50Ti60, while UV-Vis showed 46.41 % at Td60Ti50. NMR analysis revealed effective concentrations of 0.47 mM for Td70Ti60 and 0.38 mM for Td60Ti50, indicating that longer immersion times enhance absorption. These findings provide a foundation for further studies aimed at optimizing drug delivery strategies and improving the therapeutic efficacy of encapsulated agents in biological applications.

    The development of cost-effective, highly active, and stable electrocatalysts for water splitting to produce green hydrogen is crucial for advancing clean and sustainable energy technologies. Herein, we present an innovative in-situ synthesis of FeOOH nanorods@NiOOH nanosheets on nickel foam (FeOOH@NiOOH/NF) at an unprecedentedly low temperature, resulting in a highly efficient electrocatalyst for overall water splitting. The optimized FeOOH@NiOOH/NF sample, evaluated through time-dependent studies, exhibits exceptional oxygen evolution reaction (OER) performance with a low overpotential of 261 mV at a current density of 20 mA cm-2, alongside outstanding hydrogen evolution reaction (HER) activity with an overpotential of 150 mV at a current density of 10 mA cm-2, demonstrating excellent stability in alkaline solution. The water-splitting device featuring FeOOH@NiOOH/NF-2 electrodes achieves a voltage of 1.59 V at a current density of 10 mA cm-2, rivalling the state-of-the-art RuO2/NF||PtC/NF electrode system. Density functional theory (DFT) calculations unveil the efficient functionality of the Fe sites within the FeOOH@NiOOH heterojunction as the active OER catalyst, while the Ni centres are identified as the active HER sites. The enhanced performance of OER and HER is attributed to the tailored electronic structure at the heterojunction, modified magnetic moments of active sites, and increased electron density in the dx2-y2 orbital of Fe. This work provides critical insights into the rational design of advanced electrocatalysts for efficient water splitting.

    Severe restrictions on human travel and consumption during the lockdown (LD) have affected global marine traffic and operations. The LD period is ideal for studying the emissions as there were restricted human activities. Although several pollutants are emitted by ships, the most important is nitrogen dioxide (NO2), and can be considered an indicator of shipping emissions. Therefore, we examine the changes in NO2 pollution over the shipping lanes, ports and coasts across the globe during LD. Here, we find a significant decline in NO2 during LD over the major lanes, including the USA-Europe trade routes through the North Atlantic Ocean, Asia-Middle East through the Arabian Sea, Interasia, and Intereuropean through the North Sea and Baltic Sea, about 10-20%, as analysed form the TROPOMI satellite measurements. A similar reduction over the sea straight pass, such as the Cape of Good Hope and the Strait of Malacca is also estimated. Furthermore, the major global ports of Callao, Santos, Antwerp, Rotterdam, Busan, Tubarao, Richards Bay, Barcelona, Durban and Chennai exhibit a significant decrease in NO2 during LD, about 30%. The decline in NO2 over the shipping routes and ports can be attributed to reduced cargo, passenger, fishing and tanker vessel density due to the LD restrictions; consistent with the emission inventory analysis. Henceforth, this study suggests strict environmental policies in the shipping sector to curb emissions, as pollution is a great concern for public health in the port cities and coastal regions.

    BACKGROUND: Chronic obstructive pulmonary disease (COPD) significantly impacts global health due to persistent airflow limitation and inflammation. Despite standard therapies, symptoms persist. Ensifentrine, targeting both bronchoconstriction and inflammation as a dual phosphodiesterase 3 and 4 inhibitor, offers a promising therapeutic advancement for COPD management. This meta-analysis evaluates the safety and efficacy of ensifentrine in improving lung function, dyspnea, and quality of life in COPD patients.

    METHODS: We searched PubMed, Embase, and Web of Science through August 2024 for randomized controlled trials evaluating ensifentrine in COPD patients over a minimum of four weeks. Data extraction and screening utilized Knowledge software, and meta-analyses were performed using R v4.4 with a random-effects model.

    RESULTS: From 206 studies identified, four met our inclusion criteria. Ensifentrine improved FEV1 significantly at a dose of 3 mg (LS mean difference: 40.90 mL; 95 % CI: 19.65-62.15). It also improved dyspnea as measured by the Transition Dyspnea Index (TDI) (LS mean difference: 0.91; 95 % CI: 0.61-1.21) and quality of life according to the St. George's Respiratory Questionnaire-C (SGRQ-C) scores (LS mean difference: -1.92; 95 % CI: -3.28 to -0.55). Safety profiles were comparable between the ensifentrine and placebo groups, with no significant increase in treatment-emergent adverse events (TEAEs) (RR: 1.02; 95 % CI: 0.94-1.10).

    CONCLUSION: Ensifentrine significantly enhances lung function, reduces dyspnea, and improves quality of life in COPD patients, especially at a 3 mg dose. These benefits, coupled with a stable safety profile, support its use as an adjunctive therapy in COPD management.
