AbstractAimsTo help establish optimized treatment strategies for congestion in patients with acute heart failure, this study aimed to provide a detailed summary of real‐world diuretic use in hospitalized patients with heart failure requiring urgent therapy in Japan.Methods and resultsThis observational study used a Japanese medical records database to extract data of patients admitted to hospital with a heart failure diagnosis and an intravenous diuretic prescription from the day before admission to 2 days after. Time from hospital visit to first dose, second dose, and maximum dose of intravenous diuretics were determined. Patients were grouped according to whether they received diuretic modification, defined as an intravenous diuretic dose increase or concomitant use of other diuretics.ResultsOverall, 1577 patients were included in the study (without diuretic modification, n = 1140 [72.3%]; with diuretic modification, n = 437 [27.7%]). The study population was 49.5% female (n = 780) and the mean age ± standard deviation was 80.1 ± 12.7 years. Intravenous diuretic treatment was received within 1 h of their hospital visit in 43.5% of patients (686/1577) and ≤2 h in 16.4% of patients (258/1577). Among 437 patients with an inadequate response following their first dose, 42.1% received an intravenous dose titration, 56.5% received combination diuretics, and 1.4% received both. Over half of the patients (59.0% [258/437]) with diuretic modification received it after the first 24 h of the hospital visit. The median time from hospital visit to first dose titration was similar to time to first combination diuretic use (18.6 h and 17.0 h, respectively). The mean ± standard deviation duration of intravenous diuretic use was significantly longer for patients with versus without diuretic modification (6.3 ± 5.2 vs. 3.7 ± 3.2 days), and a significantly greater proportion of patients (44.6% [195/437] vs. 35.0% [399/1140]) received repeated intravenous diuretic administration. Other characteristics/outcomes of intravenous diuretic use were similar with versus without diuretic modification, including in‐hospital death (15.6% [68/437] vs. 13.9% [159/1140]) and mean ± standard deviation length of hospitalization (21.9 ± 14.7 days vs. 22.1 ± 21.2 days).ConclusionsIn Japan, real‐world patterns of intravenous diuretic administration for patients with heart failure remains far from the time‐sensitive approach recommended in Japanese, European, and United States guidelines.

AbstractIntroductionThe incidence of heart failure (HF) is increasing, largely because populations are both ageing and growing. Most clinical HF treatment trials are conducted on selected cohorts, only a few of which include elderly patients, among whom HF is common. HF registries can include all HF patients, independent of age or comorbidity profile, and thus reflect reality in healthcare management.MethodsThe Icelandic Heart Failure Registry (IHFR) was created in the autumn of 2019 and has operated since 1 January 2020. Based on the Swedish Heart Failure Registry (SwedeHF), it quickly acquired several extensions. All patients admitted for HF to the Department of Cardiology (DC) at Landspítali – The National University Hospital of Iceland are included. Several variables are collected, including the aetiology of HF, comorbidities, clinical assessment at admission, blood tests, imaging results, treatment given and medical therapy at discharge.ResultsDuring the 3 years from 2020 to 2022, the DC admitted 1890 patients. As some were readmitted during the study period, the true total was 2384 admissions. Because the IHFR 2023 edition includes 327 variables, automation of many of them is imperative for data collection.ConclusionHF is a heterogenous disease with numerous underlying factors. HF management differs among HF phenotypes. A registry can serve as an unbiased indicator of care quality and has the potential to be studied in the future to assess the long‐term effects of HF treatment. A registry like the IHFR, therefore, can impact the treatment of all patients recorded in it, reduce the rate of readmissions and even optimize HF management costs.

AbstractThis study aimed to verify the relationship between changes in thigh muscle‐localized bioelectrical impedance analysis (ML‐BIA) parameters and performance in a multiple‐set exercise. The sample consisted of 30 female university students (22.1 ± 3.2 years). The ML‐BIA parameters, including localized muscle resistance (ML‐R), reactance (ML‐Xc), and phase angle (ML‐AngF), were evaluated using a tetrapolar bioelectric impedance device operating at a frequency of 50 KHz. The multiple sets protocol was performed with an isokinetic dynamometer. For body composition, total and leg lean soft tissue (LST) were evaluated using dual X‐ray absortiometry. Student's t‐test for paired samples was used to compare the ML‐BIA parameters and thigh circumference pre and postexercise. Linear regression analysis was performed to verify the ∆ML‐PhA as a predictor of peak torque for the three sets alone while controlling for total and leg LST. There were differences in the ML‐R (∆ = 0.02 ± 1.45 Ω; p = 0.001; and E.S = 0.19), ML‐Xc (∆ = 2.90 ± 4.12 Ω; p = 0.043; and E.S = 0.36), and thigh circumference (∆ = 0.82 ± 0.60 cm; p < 0.001; and E.S = 0.16) pre‐ and post‐multiple sets. ΔML‐PhA was a predictor of performance in the first set (p = 0.002), regardless of total and leg LST. However, the ΔML‐PhA lost its explanatory power in the other sets (second and third), and the variables that best explained performance were total and leg LST. The ML‐BIA (ML‐R and ML‐Xc) parameters were sensitive and changed after the multiple sets protocol, and the ΔML‐PhA was a predictor of performance in the first set regardless of the total and leg LST.

AbstractDolines are a widespread karst landform, and understanding their genesis can provide critical information about the evolution of subsurface karstification and groundwater flow zones. Swarms of collapse dolines characterise the karst in the southern portion of the Irecê Basin, northeastern Brazil. The basin comprises Neoproterozoic carbonate rocks approximately 100 m thick, bounded by less soluble older quartzites. The distribution of dolines is not uniform, as they cluster along NW‐SE axes and are aligned with cave systems and permeability (fracture) corridors mostly associated with the Almas and Água de Rega ephemeral rivers. Detailed analysis of sectors with a higher density of dolines was performed using LiDAR and unmanned aerial vehicle (UAV) imagery at two different scales to obtain morphometric and orientation patterns. As expected, scale dependency is observed, with an increase in density and circularity index at a higher resolution scale, but a decrease in mean area and perimeter. However, Voronoi polygon indices are similar at both scales (6.86 ± 1); the departure from the more stable number of six due to the clustering of dolines associated with NW‐SE oriented structural trends. Doline density trends closely follow the orientation of caves, but they are not always spatially connected, since doline evolution may either occlude the caves or be related to a non‐identified void. The Irecê Basin karst system displays a continuum of landforms evolving initially from high‐density fracture zones (fracture corridors), which work as favourable dissolution zones, grading into more integrated flow routes, cave systems and eventually clusters of collapse dolines. Collapse dolines are widespread karst landforms worldwide, and their genesis requires the presence of dissolution voids at depth, which may pass undetected from the surface. In some sectors of Irecê Basin, the existence of doline alignments but the absence of known caves indicates the potential of collapse dolines to be used as proxies for subsurface karstification. Such an approach may allow the prediction of the location and orientation of subsurface zones of enhanced dissolution that can potentially represent productive aquifers or favourable zones for geofluids.
Carbon‐Based Cathode Design for Next‐Generation Potassium‐Sulfur Batteries: Status and Perspective

Published: August 2024

ABSTRACTThe increasing concern for environmental pollution has fastened the development of energy storage devices. Among various devices, lithium‐ion battery (LIB) technology has been leapfrogged owing to its stable performance for various applications ranging from electronic gadgets to electric vehicles (EVs). For ever‐increasing number of EVs has increased the demand for batteries increasing the overall cost. An alternative energy storage device that can replace the dependence on lithium reserves can be another game changer in this area. Potassium‐sulfur batteries (KSBs) have attracted enormous attention owing to the higher abundance of sulfur and potassium. In addition, sulfur bears the highest capacity as a cathodic material (nearly five times higher than the commercial LIBs) and when clubbed with potassium anode can deliver a theoretical energy density of 914 Wh/kg (significantly higher for EVs). However, KSB development is still in the nascent stage owing to the intrinsic challenges including insulating sulfur, volume variation, and shuttle effect of polysulfides. In addition, unstable potassium anode and its dendrite formation is another thorny problem for KSB. The use of carbon matrices for cathode fabrication has been proven to be an excellent choice by initial research on KSB and experience with other metal‐sulfur batteries. This can be related to the higher electronic conductivity of carbon, easy tunability, high specific surface area, and porous morphology. This review is an attempt to show the usage of carbon as a sulfur host for KSBs and its performance. Further, we shed light on flexible and binder‐free carbon electrodes for the development of KSBs, which can be adopted to develop flexible batteries to be used in wearable devices. Finally, we present our perspective for developing a high‐performance carbon‐based cathode material for developing a reliable and long‐cycle life KSB.
Deep‐frying impact on food and oil chemical composition: Strategies to reduce oil absorption in the final product

Published: August 2024

AbstractDuring frying, oils can deteriorate due to autoxidation and hydrolytic alterations, processes influenced by the oil's fatty acid composition (FAC) and antioxidant content. However, there are different techniques to improve fried food quality and reduce oil absorption. This review aims to assess existing literature on the interactions between frying methods, oil selection, and the chemical composition of foods. To achieve this goal, the article examines the impact of oil FAC, antioxidants, pretreatments, and alternative frying technologies. A literature search was conducted from 2016 to 2023. The keywords used were (AND/OR) frying, fried foods, oil, oil absorption, and fatty acids. Oils rich in monounsaturated fatty acids and antioxidants, such as olive oil, are recommended for their nutritional benefits and improved oil stability. The water content and structure of the food also play a significant role in oil absorption. Pretreatments to diminish food moisture content contribute to a lower oil absorption in the fried food while mitigating excessive accumulation of lipid oxidation products. Proper selection of frying oils, incorporation of antioxidants, and the use of pretreatments could help prevent chemical changes and minimize oil absorption during frying. These measures contribute to maintaining the nutritional quality and safety of fried foods while also enhancing their overall sensory appeal.

Published: August 2024

ABSTRACTChromosomal rearrangements involving Janus kinase 2 (JAK2) are rare but recurrent findings in lymphoid or myeloid neoplasia. Detection of JAK2 fusion genes is important as patients with aberrantly activated JAK2 may benefit from treatment with tyrosine kinase inhibitors such as ruxolitinib. Here, we report a novel fusion gene between the transcriptional co‐repressor‐encoding gene transducin‐like enhancer of split 3 (TLE3) and JAK2 in a patient initially diagnosed with chronic eosinophilic leukemia with additional mutations in PTPN11 and NRAS. The patient was successfully treated with the JAK2 inhibitor ruxolitinib for 8 months before additional somatic mutations were acquired and the disease progressed into an acute lymphoblastic T‐cell leukemia/lymphoma. The present case shows similarities to previously reported cases with PCM1::JAK2 and BCR::JAK2 with regard to disease phenotype and response to ruxolitinib, and importantly, provides an example that also patients harboring other JAK2 fusion genes may benefit from treatment with JAK2 inhibitors.
Medicaid expansion and opioid prescriptions: Evidence from the Medical Expenditure Panel Survey
Authors: McClellan Chandler , Moriya Asako 
Published: August 2024

AbstractEvidence is mixed on whether increased access to insurance, specifically through the ACA's Medicaid expansion, exacerbated the opioid public health crisis through increased opioid prescribing. Using survey data on retail prescription drug fills from 2008 to 2019, we did not find a significant relationship between Medicaid expansion and opioid prescribing in the newly eligible Medicaid population. It may be that the dangers of opioids were known well enough by the time of the Medicaid expansion that lack of access to care was no longer a binding constraint on opioid prescription receipt.

AbstractIn this global phase 2 study in patients with relapsed/refractory follicular lymphoma (FL), zandelisib was administered on intermittent dosing to mitigate immune‐related adverse events and infections that have been reported with oral PI3Kδ inhibitors administered daily continuously. Eligible patients with measurable disease and progression after at least two prior therapies were administered zandelisib until disease progression or intolerability. The primary efficacy endpoint was objective response rate (ORR) and the key secondary efficacy endpoint was duration of response (DOR). We report on 121 patients with FL administered zandelisib on intermittent dosing after 8 weeks of daily dosing for tumor debulking. The median number of prior therapies was 3 (range, 2–8) and 45% of patients had refractory disease. The ORR was 73% (95% confidence interval [CI], 63.9–80.4), the complete response (CR) rate was 38% (95% CI, 29.3–47.3), and the median DOR was 16.4 months (95% CI, 9.5–not reached). With a median follow‐up of 14.3 months (range, 1–30.5), the median progression‐free survival was 11.6 months (95% CI, 8.3–not reached). Twenty‐one patients (17%) discontinued therapy due to an adverse event. Grade 3–4 class‐related toxicities included 6% diarrhea, 5% lung infections, 3% colitis (confirmed by biopsy or imaging), 3% rash, 2% AST elevation, and 1% non‐infectious pneumonitis. Zandelisib achieved a high rate of durable responses in heavily pretreated patients with relapsed/refractory FL. The intermittent dosing resulted in a relatively low incidence of severe class‐related toxicities, which supports the evaluation of zandelisib as a single agent and in combination with indolent B‐cell malignancies.

AbstractBiomarkers for immune checkpoint inhibitors (ICIs) response and resistance include PD‐L1 expression and other environmental factors, among which the gut microbiome (GM) is gaining increasing interest especially in lymphomas. To explore the potential role of GM in this clinical issue, feces of 30 relapsed/refractory lymphoma (Hodgkin and primary mediastinal B‐cell lymphoma) patients undergoing ICIs were collected from start to end of treatment (EoT). GM was profiled through Illumina, that is, 16S rRNA sequencing, and subsequently processed through a bioinformatics pipeline. The overall response rate to ICIs was 30.5%, with no association between patients clinical characteristics and response/survival outcomes. Regarding GM, responder patients showed a peculiar significant enrichment of Lachnospira, while non‐responder ones showed higher presence of Enterobacteriaceae (at baseline and maintained till EoT). Recognizing patient‐related factors that may influence response to ICIs is becoming critical to optimize the treatment pathway of heavily pretreated, young patients with a potentially long‐life expectancy. These preliminary results indicate potential early GM signatures of ICIs response in lymphoma, which could pave the way for future research to improve patients prognosis with new adjuvant strategies.

AbstractImmunotherapy shows great promise for treating advanced cancers, but its effectiveness varies widely among different patients and cancer types. Identifying biomarkers and developing robust predictive models to discern which patients are most likely to benefit from immunotherapy is of great importance. In this context, we have developed the tumor immunotherapy gene expression R package (tigeR 1.0) to address the increasing need for effective tools to explore biomarkers and construct predictive models. tigeR encompasses four distinct yet closely interconnected modules. The Biomarker Evaluation module enables researchers to evaluate whether the biomarkers of interest are associated with immunotherapy response via built‐in or custom immunotherapy gene expression data. The Tumor Microenvironment Deconvolution module integrates 10 open‐source algorithms to obtain the proportions of different cell types within the tumor microenvironment, facilitating the investigation of the association between immune cell populations and immunotherapy response. The Prediction Model Construction module equips users with the ability to construct sophisticated prediction models using a range of built‐in machine‐learning algorithms. The Response Prediction module predicts the immunotherapy response for the patients from gene expression data using our pretrained machine learning models or public gene expression signatures. By providing these diverse functionalities, tigeR aims to simplify the process of analyzing immunotherapy gene expression data, thus making it accessible to researchers without advanced programming skills. The source code and example for the tigeR project can be accessed at http://github.com/YuLab-SMU/tigeR.

AbstractNickel tetraphenyl‐porphyrin (NiTPPH₂) and zinc tetra(4‐methophenyl)‐porphyrin (ZnTPPH₂(p‐methyl)) were successfully synthesized and characterized using 1H NMR spectroscopy. Their antioxidant activities and interactions with the superoxide anion radical () were evaluated using cyclic voltammetry. Remarkably, NiTPPH₂ displayed superior antioxidant activity with an IC50 value of 54.57 μg mL−1, significantly outperforming α‐tocopherol (IC50 = 353.27 μg mL−1), indicating its potential as a potent antioxidant. Binding free energy calculations demonstrated that electrostatic interactions predominantly govern the binding, with values of −23.47 kJ mol−1 for NiTPPH₂ and −22.50 kJ mol−1 for ZnTPPH₂(p‐methyl). These values suggest robust binding affinities with . Quantum chemical parameters, obtained through density functional theory (DFT), showed a strong correlation with experimental results, validating the computational approach. Additionally, ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) and drug‐likeness assessments, alongside molecular docking studies, highlighted favorable pharmacokinetic profiles and binding affinities. These findings underscore the potential of NiTPPH₂ and ZnTPPH₂(p‐methyl) as promising candidates for antioxidant therapy, exhibiting drug‐like properties and favorable pharmacokinetics. This research advances the understanding of these porphyrin derivatives and their application in the development of novel antioxidant therapeutics.
