AbstractExploring efficient, abundant, economical and stable materials for sustainable energy applications, such as electrochemical water splitting and supercapacitance, is a challenging task. Mixed transition metal spinel ferrites can rationally be customized to attain these features and deliver enhanced electrochemical activity. The catalytic performance of spinels is remarkably influenced by tuning the cationic occupancy at the tetrahedral or octahedral position. Herein, a set of spinel Ni1‐xZnxFe2O4 (0≤x≤1) nanocomposites were obtained via a scalable solventless thermolysis of metal acetylacetonate precursors at relatively mild temperatures. A suite of techniques such as powder p‐XRD, EDX, SEM, TEM, HRTEM, and SAED were employed to confirm the formation of the Ni−Zn ferrite solid solutions. It was found that small amounts of Ni at tetrahedral sites were beneficial for charge storage and hydrogen evolution. For instance, Ni0.2Zn0.8Fe2O4 nanocomposite demonstrated superior HER activity with a much lower overpotential of 87 mV compared to the pristine NiFe2O4 (213 mV) or ZnFe2O4 (164 mV) catalysts. However, Ni‐occupied tetrahedral sites were not suitable for OER, whereby the pristine ZnFe2O4 displayed high catalytic activity with an overpotential of 330 mV, outperforming other electrode compositions. The study helps to identify suitable compositions and site tuning for HER, OER and supercapacitors.

Published: June 2024

AbstractIn this work, copper oxide (CuO) nanograss (NGs) were synthesized on copper foil as electrodes through anodization and annealing processes. After the successful synthesis of the CuO NG electrode, it was characterized using field emission scanning electron microscopy (FESEM) and X‐ray diffraction (XRD) analysis. Anodization duration was optimized for NG synthesis and was found to be 20 min with the help of FESEM analysis. The synthesized electrodes were used to analyze the organophosphate pesticides (OPPs), namely ‘malathion’ and ‘chlorpyrifos’, in the absence and presence of interfering molecules using differential pulse voltammetry (DPV). The proposed sensor functions based on the current inhibition ratio. The parameters like pH, accumulation time, and ionic strength of supporting electrolyte were optimized to be 7 pH, 9 min, and 0.1 M potassium chloride (KCl), respectively, for determining the current inhibition ratio (ΔI/I0). The developed sensor was sensitive and selective, with limit of detection (LOD) as low as 1 ppb for both pesticides. The limit of quantification (LOQ) was 1 ppb for chlorpyrifos and 10 ppb for malathion. The sensor's selectivity was also studied by adding Pb(NO3)2, Zn(NO3)2, NiCl2, and carbendazim to a fixed malathion and chlorpyrifos concentration, and minimal interferences were observed in the detection of malathion and chlorpyrifos. The sensor's functionality was validated using an unknown concentration of malathion and chlorpyrifos in water and food samples with an average recovery of 95% when analyzed with the electrochemical method and high performance liquid chromatography (HPLC). The sensitivity of the electrochemical sensor for chlorpyrifos detection was found to be 0.6678 μA/ppb, and for malathion detection, it was found to be 1.139 μA/ppb.

AbstractBackgroundPhosphatidylinositol 3‐kinase (PI3K) inhibitors transformed management of various malignancies. This study preclinically characterized TQ‐B3525 (dual PI3Kα/δ inhibitor) and assessed the recommended phase 2 dose (RP2D), safety, efficacy, and pharmacokinetics in relapsed or refractory (R/R) lymphoma or advanced solid tumors (STs).MethodsOral TQ‐B3525 was given at eight dose levels on a 28‐day cycle. Primary end points were dose‐limiting toxicity (DLT), maximum tolerated dose (MTD), and safety.ResultsTQ‐B3525 showed high selectivity and suppressed tumor growth. Between June 12, 2018, and November 18, 2020, 80 patients were enrolled (63 in dose‐escalation cohort; 17 in dose‐expansion cohort). Two DLTs occurred in two (two of 63, 3.2%) DLT‐evaluable patients; MTD was not identified. TQ‐B3525 at 20 mg once daily was selected as RP2D. Grade 3 or worse treatment‐related adverse events mainly included hyperglycemia (16.3%), neutrophil count decreased (15.0%), and diarrhea (10.0%). Two (2.5%) treatment‐related deaths were reported. Sixty patients with R/R lymphoma and 11 advanced STs demonstrated objective response rates of 68.3% and 9.1%, disease control rates of 91.7% and 54.6%, median progression‐free survivals of 12.1 and 1.1 months; median overall survivals were not reached.ConclusionTQ‐B3525 exhibited rapid absorption and a nearly proportional increase in exposure. Acceptable safety and promising efficacy support further investigation of TQ‐B3525 (20 mg once daily) for R/R lymphoma.
Tumor and cancer stem cells‐derived exosomes interplay: A secret of cancer complications
Authors: Sonar Swarup , Nyahatkar Sidhanti , Kalele Ketki 
Published: June 2024

AbstractCancer stem cells (CSCs) are a small subset of tumor cells, efficient in self‐renewal within the tumor and also play a vital role in cancer resistance and metastasis. Recent cancer research has focused on exosomes, a tiny subpopulation of extracellular vesicles (EVs), known for their role in intercellular communication, and significantly contributing to tumor development and metastasis (Tumor derived exosomes‐TEXs). These exosomes complicate cancer treatment by promoting tumor and CSC formation and developing drug and therapeutic resistance. This article explores how tumor‐derived exosomes impact CSC survival, proliferation, and resistance to therapies, leading to tumor recurrence. In a tumor microenvironment (TME), exosomes facilitate tumor growth and metastasis. Targeting exosomes could disrupt CSC communication and improve cancer treatment efficacy. Current studies highlight the role of CSCs exosomes in cancer progression and therapeutic resistance. Understanding CSCs exosome‐based cell‐to‐cell communication in tumor opens a new horizon in cancer therapeutics development.

Published: June 2024

AbstractAimsPatients with transthyretin amyloid cardiomyopathy (ATTR‐CM) present with diverse left ventricular ejection fraction (LVEF). This study assessed tafamidis efficacy by baseline LVEF in the phase 3 Tafamidis in Transthyretin Cardiomyopathy Clinical Trial (ATTR‐ACT) and its long‐term extension (LTE) study.Methods and resultsPatients were randomized to 30 months of tafamidis or placebo treatment in ATTR‐ACT. On completion, patients could join an LTE study to receive tafamidis. All‐cause mortality (death, heart transplant, or cardiac mechanical assist device implantation) from baseline to the end of follow‐up was assessed in patients continuously treated with tafamidis (80 mg meglumine or 61 mg free acid) or delayed tafamidis treatment (placebo in ATTR‐ACT; tafamidis in the LTE study) according to baseline LVEF (<50% or ≥50%). Supportive outcomes were evaluated over a shorter follow‐up. Patients with baseline LVEF <50% (n = 177: 88 tafamidis‐ and 89 placebo‐treated) had signs of more severe heart failure, a higher proportion were Black, and had variant ATTR‐CM than those with LVEF ≥50% (n = 171: 85 tafamidis‐ and 86 placebo‐treated). At the end of follow‐up (median 60–64 months), all‐cause mortality was numerically higher in patients with baseline LVEF <50%; however, consistent with supportive findings, continuous tafamidis treatment was associated with a 47% reduction in mortality risk compared with delayed tafamidis treatment in patients with LVEF <50% and ≥50% (hazard ratio 0.53 [95% confidence interval 0.367–0.758]; p < 0.001, and 0.53 [0.344–0.818]; p < 0.01, respectively).ConclusionsEarly initiation of tafamidis is associated with reduced mortality in patients with ATTR‐CM, irrespective of initial LVEF value.Clinical Trial Registration: ClinicalTrials.gov NCT01994889, NCT02791230.

Published: June 2024

AbstractThis review and meta‐analysis aimed to describe the current rugby‐7s injury epidemiological literature by examining injury data from both sexes, all levels of play, and their associated risk factors. Studies published up until March 2024 were included. These studies were retrieved from six databases using search terms related to rugby‐7s or sevens, tackle, collision, collision sport, injury, athlete, incidence rate, mechanism, and risk factor. Only peer‐reviewed original studies using prospective or retrospective cohort designs with a clearly defined rugby‐7s sample were considered. Included studies needed to report one injury outcome variable. Non‐English and qualitative studies; reviews, conference papers, and abstracts were excluded. Twenty studies were included. The meta‐analysis used the DerSimonian–Laird continuous random‐effects method to calculate the pooled estimated means and 95% confidence interval. The estimated mean injury incidence rate for men was 108.5/1000 player‐hours (95% CI: 85.9–131.0) and 76.1/1000 player‐hours (95% CI: 48.7–103.5) for women. The estimated mean severity for men was 33.9 days (95% CI: 20.7–47.0) and 44.2 days (95% CI: 32.1–56.3) for women. Significantly more match injuries occurred in the second half of matches, were acute, located at the lower limb, diagnosed as joint/ligament, and resulted from being tackled. Fatigue, player fitness, and previous injuries were associated with an increased risk of injury. There were no statistically significant differences between women's and men's injury profiles. However, the inherent cultural and gendered factors which divide the two sports should not be ignored. The findings from this review will help pave the way forward beyond the foundational stages of injury prevention research in rugby‐7s.

AbstractObjectivesThis study aimed to evaluate the efficacy of different repetitive transcranial magnetic stimulation (rTMS) modes in stroke patients with cognitive impairment, and to rank the best option according to the outcome measures.MethodsLiterature was searched in PubMed, Cochrane Library, Web of Science, Embase, SinoMed, China National Knowledge Infrastructure, Wanfang Database, and VIP Database, from database inception to September 2023. We included randomized controlled trials (RCTs) investigating the efficacy of all rTMS modes for post‐stroke cognitive impairment. The selected studies assessed at least one of the following outcome measures: Montreal Cognitive Assessment (MoCA), Mini‐Mental State Examination (MMSE), P300 latency and amplitude, and modified Barthel Index (MBI) or BI. Two researchers independently conducted data extraction. Quality assessment was performed using RevMan 5.3 software based on the Cochrane Collaboration's tool, and statistical analysis was conducted by GeMTC 0.14.3 software and Stata 17.0 software.ResultsThe network meta‐analysis included 74 RCTs with a total of 5478 patients. The best probability ranking indicated that intermittent theta burst stimulation (iTBS) was the most effective in enhancing MoCA, MMSE and MBI scores (85%, 54%, 42%, respectively), followed by 10 Hz rTMS (79%, 50%, 39%, respectively), for P300 amplitude, ≤1 Hz rTMS was ranked first (52%).ConclusionsThe current limited evidence suggests that iTBS may be the optimal approach for improving cognitive and daily life abilities of stroke patients, followed by 10 Hz rTMS, ≤1 Hz rTMS may be the preferred option for enhancing P300 amplitude.Trail registration: PROSPERO 2023 CRD42023424771 available from: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=424771.

Published: June 2024

AbstractObjectivesThe objective of this in vitro study was to assess the efficiency of incorporating Biosilicate particles (30 and 50 mg) into an experimental orodispersible film and its efficacy in the remineralization process of bovine dental enamel under cariogenic and erosive challenges.MethodsNinety‐nine intact incisors, devoid of cracks or fractures, yielding 198 samples (6 × 6 × 2 mm) via vestibular sectioning using a low‐speed diamond disc under water cooling. After flattening the enamel surface with 600, 1200, and 2000 grit sandpaper, the samples were divided into two groups based on the challenges they underwent: cariogenic (0.1 M lactic acid at pH 5.0) or erosive (0.05 M citric acid solution at pH 2.3). Samples from each challenge were further categorized into 11 groups (n = 9) according to the duration of cariogenic (3, 7, and 14 days) or erosive (3, 7, and 10 days) challenge, along with positive control groups (fragments untreated with challenges and treated with different Biosilicate concentrations) and negative controls (fragments treated with artificial saliva for the same periods established for cariogenic and erosive challenges). Treatments with orodispersible films containing Biosilicate (30 and 50 mg) were administered for 2 min per day for 15 days.ResultsThe highest remineralizing potential was observed in samples treated with Biosilicate after 14 days of cariogenic challenge, irrespective of the concentration tested. For samples subjected to erosive challenge, erosion time did not affect Biosilicate's remineralizing potential.ConclusionBiosilicate shows promise in terms of remineralizing potential in enamel subjected to cariogenic challenge due to its ability to form hydroxycarbonapatite in mineralized tissues.

AbstractPrior research suggests that culturally aligned, accessible and lower‐barrier interventions are well‐placed to align with the needs of American Indian and Alaska Native (AI/AN) people with alcohol use disorder (AUD). Taking into account community members' suggestions and the need for physical distancing during the COVID‐19 pandemic, our team developed a protocol for virtual Harm Reduction Talking Circles (HaRTC) to incorporate these points. The aims of this 8‐week, single‐arm pilot were to initially document feasibility, acceptability, and outcomes associated with attendance at virtual HaRTC, which integrates the accessibility of virtual connection, a lower‐barrier harm‐reduction approach, and a culturally aligned intervention. Participants (N = 51) were AI/AN people with AUD (current or in remission) across 41 Tribal affiliations and 25 US states. After a baseline interview, participants were invited to attend 8, weekly virtual HaRTC sessions. At the baseline, midpoint and post‐test assessments, we collected data on virtual HaRTC acceptability, cultural connectedness, quality of life, and alcohol outcomes. Of the 123 people approached, 63% were interested in and consented to participation. Participants attended an average of 2.1 (SD = 2.02) virtual HaRTC sessions, with 64% of participants attending at least one. On a scale from 1 to 10, participants rated the virtual HaRTC as highly acceptable (M = 9.3, SD = 1.9), effective (M = 8.4, SD = 2.9), culturally aligned (M = 9.2, SD = 1.5), helpful (M = 8.8, SD = 1.9), and conducted in a good way (M = 9.8, SD = 0.5). Although the single‐arm study design precludes causal inferences, participants evinced statistically significant decreases in days of alcohol use and alcohol‐related harm over the three timepoints. Additionally, both sense of spirituality, which is a factor of cultural connectedness, and health‐related quality of life increased over time as a function of the number of HaRTC sessions attended. Virtual HaRTC shows initial feasibility and acceptability as a culturally aligned intervention for AI/AN people with AUD. Future randomized controlled trials will provide a test of the efficacy of this approach.
A highly efficient, eco‐friendly method for antireflection nanostructures on poly (ethylene terephthalate)
Authors: Zhou Hongkun , Mu Lan , Liang Ruibin , Lan Linfeng 
Published: June 2024

AbstractAntireflection surfaces are widely used in optical devices (such as vehicle display, solar cells, and architectural glass) to reduce the reflection and increase transmittance. Plasma etching shows great potential in making subwavelength antireflection structures for its advantage of scalable, low‐cost, and applicable in flexible substrates. Here, we demonstrate an antireflection nanostructure by O2 plasma etching on poly (ethylene terephthalate) (PET) substrate without additional corrosive gas species or antireflective coatings. Nanopores on the surface were formed due to the different etching rates of the organic region and silica region of the surface. The solar weighted average transmittance was improved from 91.6% to 94.8% for single‐side treated PET with silica antiblocking layer. The transmission increment was attributed to the gradient refractive index of the nanostructured surface due to the elimination of step discontinuity in refractive index. The result shows a highly efficient, eco‐friendly, solvent‐free, economical, and sputtering target‐free method for reducing the reflection and increasing the transmittance of the substrates.
Critical appraisal of total gastrectomy plus total colectomy with hyperthermic intraperitoneal chemotherapy as a treatment for advanced pseudomyxoma peritonei
Authors: Sugarbaker Paul H. , Chang David 
Published: June 2024

AbstractBackgroundThe absolute requirement for a long‐term favorable result with cytoreductive surgery for pseudomyxoma peritonei is a complete resection of all visible disease. A combination of parietal peritonectomy procedures and visceral resections is required for this to occur. The cytoreductive surgery is supplemented by hyperthermic intraperitoneal chemotherapy.MethodsWe searched our database and secured files for patients who required a total gastrectomy and a total colectomy to achieve a complete cytoreductive surgery. Survival of low‐grade mucinous neoplasm (LAMN) and mucinous appendiceal adenocarcinoma (MACA) histologies were determined. Clinical and histologic variables were assessed for their impact on survival.ResultsThirteen of 450 patients (2.9%) with LAMN histology and 14 of 186 patients (7.5%) with MACA histology had these visceral resections. Median survival of these 27 patients was 10 years. LAMN and MACA patients showed the same survival. For LAMN histology, this requirement for extensive visceral resection markedly reduced survival (p < 0.0001). For MACA, there was no adverse impact on survival (p = 0.4359). Class 4 adverse events caused reduced survival (p = 0.0014).ConclusionsA 10‐year median survival accompanies total gastrectomy plus total colectomy for advanced pseudomyxoma peritonei. Systemic chemotherapy and class 4 adverse events reduced survival.

Published: June 2024

AbstractBackground and ObjectivesGastric cancer (GC) prognosis is influenced by the extent of the tumor, lymph node involvement (LNM), and metastasis. Endoscopic resection (ER) or gastrectomy with lymphadenectomy are standard treatments for early GC (EGC). This study evaluated LNM frequency according to eCura categories, clinicopathological characteristics, disease‐free (DFS), and overall (OS) survival rates.MethodsWe included EGC patients who underwent curative gastrectomy between 2009 and 2020 from our single‐center database. Anatomopathological and clinical reports were reviewed to analyze eCura categories.ResultsWe included 160 EGC patients who underwent gastrectomy with eCura categories A, B, and C, comprising 26.3%, 13.8%, and 60%, respectively. Baseline clinical characteristics showed no intergroup disparities. LNM incidence for A, B, and C was 4.8%, 18.2%, and 19.8%. When evaluating the criteria for ER and its association with eCura categories, we found that 95.2% of eCura A and 100% of eCura B patients had classic or expanded criteria for ER. On the other hand, 97.9% of eCura C patients were referred to surgical resection. Multivariate analysis demonstrated that lymphatic (OR = 5.57, CI95% = 1.45–21.29, p = 0.012) and perineural (OR = 15.8, CI95% = 1.39–179.88, p = 0.026) invasions were associated with a higher risk of LNM. No significant differences in DFS or OS were found among eCura categories.ConclusionThe eCura categories were associated with the occurrence of LNM. In most patients, those with classic and expanded indication criteria for ER were classified as eCura A and B.
