Published: August 2024

AbstractHydrocephalus is the most common and devastating condition affecting the fetus. The aim of this study was to provide a comprehensive overview of the relevant literature through bibliometric analysis. The survey covers the articles related to congenital hydrocephalus published in the Web of Science Core Collection (WoSCC) database from January 1, 2003 to December 31, 2022. In addition to repeated literature, reviews and articles are included. We visualized the annual publication number, citation frequency, country/region, institution, author, periodical, and keywords with a range of software such as VOSviewer (1.6.18), Microsoft Excel 2019 (Redmond) and online analysis platform (https://bibliometric.com/ document). The results showed that the United States made the most important contribution to the research on fetal hydrocephalus. China's contribution has grown and developed strongly in recent years. The key words were mainly divided into four categories: basic research, epidemiology, treatment, and diagnostics. The number of publications related to fetal hydrocephalus has increased significantly, and it has a good development prospect in prenatal diagnosis and treatment.

Published: August 2024

AbstractMetal halide perovskites have demonstrated considerable promise across various optoelectronic applications. Surface passivation serves as a pivotal strategy to obtain high‐quality perovskite materials, either in a manner of bulk thin film or nanocrystal, with superior optoelectronic properties and stability. The current research focus in this regard primarily revolves around the use of organic molecules to passivate the surface of perovskites. However, organic passivation molecules always suffer from chemical instability and weak secondary bonding modes, resulting in an unstable surface passivation motif. Inorganic materials, possessing more stable chemical structures and stronger chemical bonding than their organic counterparts, offer the opportunities to construct more robust passivation for the perovskite surfaces. Herein, in this review, we summarized and assessed recent advancements in inorganic surface passivation strategies for perovskite materials and devices, ranging from nanocrystals to bulk films. By discussing the mechanisms behind various inorganic passivation strategies, we aim to offer mechanistic insights and guidelines for future developments of more targeted surface passivation approaches tailored for perovskite materials and devices.
Time for a renovation? A case study on the recruitment and retention of women into the turfgrass industry
Authors: Letot Carson , Merrick Brandi , Cho Joseph 
Published: August 2024

AbstractThere is a labor shortage in the turfgrass industry due to a decline in interested applicants, as well as a lack of gender diversity. Women make up roughly 2%–4% of the entire membership in the major professional associations for turfgrass managers in North America. There are many barriers that stand in the way of fixing the shortage and diversifying the workforce, but before interventions can be initiated, the current pathways of entry and sentiments held by those women in the industry must be investigated. A case study approach was used to assess the recruitment and retention of women in the golf course maintenance industry through a survey instrument administered to a sample of women who have volunteered on the golf course maintenance crew at the Women's United States Open Championships from 2021 to 2023. Results indicated a lack of exposure to the turfgrass industry for recruiting women, as well as insufficient support for mentorship and significant harassment events for those already in the industry. The current study offers a baseline to begin targeted work investigating specific challenges in the turfgrass industry that will improve the experience for women and promote future diversification and mentorship initiatives.

AbstractBackgroundThe quest to manufacture large amounts of syngas to bridge fossil fuels and the renewable energy ecosystem stimulates the creation of efficient and stable heterogeneous catalysts. The NiCeO2 catalysts, synthesized via ultrasonic‐assisted citric acid complexation, are highly efficient for the dry reforming of methane (DRM) reaction. Different promoter metals (Zr, La and Sr) were tested for catalytic performance and syngas production. A range of analyses, including X‐ray diffraction (XRD), N2 physisorption, H2 temperature‐programmed reduction, CO2 temperature‐programmed desorption, field emission scanning electron microscopy (FESEM), transmission electron microscopy and X‐ray photoelectron spectroscopy, were employed to characterize the physicochemical properties of the catalysts.ResultsXRD results indicated the formation of NiO, CeO2, solid solution ceria–zirconia, perovskite LaNiO3 and SrNiO3 crystalline phases. FESEM results showed the promoted catalysts (Zr, La, Sr) produce large pores to facilitate reactant diffusion, with zirconia specifically creating a spiderweb morphology. At 800 °C, the CH4 and CO2 conversions follow the sequence of NiCeO2 catalyst (CH4 = 54%, CO2 = 45%) < Sr/NiCeO2 (CH4 = 60%, CO2 = 67%) < La/NiCeO2 (CH4 = 85%, CO2 = 84%) < Zr/NiCeO2 (CH4 = 95%, CO2 = 87%). The integration of promoters in DRM catalysts has notably improved carbon formation resistance, as evidenced by the following ranking: Zr/NiCeO2 (5.1 wt%) < commercial catalyst (6.0 wt%) < La/NiCeO2 (7.85 wt%) < Sr/NiCeO2 (10.9 wt%) < NiCeO2 (11.3 wt%).ConclusionThis study demonstrates that incorporating promoters, particularly Zr, in NiCeO2 significantly enhances resistance to carbon formation. It offers valuable insights into selecting metal catalyst promoters for excellent catalytic performance in DRM. © 2024 Society of Chemical Industry (SCI).
Amino acid surface modified bioglass: A candidate biomaterial for bone tissue engineering1

Published: August 2024

AbstractBioglasses are solid materials consisted of sodium oxide, calcium oxide, silicon dioxide and phosphorus in various proportions and have used in bone tissue engineering. There have been ongoing efforts to improve the surface properties of bioglasses to increase biocompatibility and performance. The aim of the present study is to modify the bioglass surface with an amino acid mixture consisting of arginine, aspartic acid, phenylalanine, cysteine, histidine and lysine, to characterize the surface, and to evaluate the performance and biocompatibility in vitro and in vivo. The untreated bioglass, bioglass kept in simulated body fluid (SBF), and modified bioglass were used in further evaluation. After confirmation of the surface modification with FT‐IR analyses and SEM analyses, MC3T3‐E1 preosteoblasts adhesion on the surface was also revealed by SEM. The modified bioglass had significantly higher ALP activity in colorimetric measurement, rate of calcium accumulations in Alizarin red s staining, lower rate of cell death in Annexin‐V/PI staining to determine apoptosis and necrosis. Having higher cell viability rate in MTT test and absence of genotoxicity in micronucleus test (OECD 487), the modified bioglass was further confirmed for biocompatibility in vitro. The results of the rat tibial defect model revealed that the all bioglass treatments had a significantly better bone healing score compared to the untreated negative control. However, the modified bioglass exhibited significantly better bone healing efforts especially during the first and the second months compared to the other bioglass treatment treatments. As a result, the amino acid surface modification of bioglasses improves the surface biocompatibility and osteogenic performance that makes the amino acid modified bioglass a better candidate for bone tissue engineering.Research Highlights
Bioglass surface modification with amino acids contributes to bioglass‐tissue interaction with an improved cell attachment.
Modified bioglass increases in vitro Alp activity and calcium accumulation, and also positively affects cell behavior by supporting cell adaptation.
Bioglass exerts osteogenic potential in vivo especially during early bone healing.

AbstractPediatric low‐hypodiploidy B‐cell acute lymphoblastic leukemia (LH‐ALL) with TP53 variants has been proposed to be considered a manifestation of Li‐Fraumeni syndrome (LFS). However, our study demonstrates that of the majority the pathogenic variants in the TP53 gene are somatic (70.5%), and only 12.5% of patients with germline fulfilled the criteria of LFS. We also describe the first case of hypodiploid BCP‐ALL with a mosaic pathogenic mutation in TP53 and the first case of the persistence of clonal hematopoiesis with the TР53 gene mutation in the child during 3‐year minimal residual disease‐negative remission, similar to what has been described in adults.

AbstractWe examined the impact of a hospital medicine medical procedure service (MPS) on hospital length of stay (LOS), postprocedure LOS, and completion of procedures on weekends. We included 4952 patients admitted to our large academic hospital between July 1, 2021 and July 31, 2023 who underwent thoracentesis, paracentesis, or lumbar puncture (LP). MPS performed 30% (1499) of these procedures. After adjusting for age, sex, body mass index, Charlson comorbidity score, and procedure type, procedure performance by MPS was associated with a shorter total hospital LOS (incidence rate ratio [IRR]: 0.93; 95% confidence interval [CI]: 0.87–0.99) and postprocedure LOS (IRR: 0.82; 95% CI: 0.76–0.88). Also, MPS‐performed procedures were twice as likely to occur on weekends compared to non‐MPS‐performed procedures (odds ratio [OR]: 2.05; 95% CI: 1.75–2.41). These findings support the beneficial impact of MPS on operational efficiency, an important outcome for both patients and hospitals.

AbstractTo clarify the relevance of physical activity (PA) with respect to a decrease in minimal joint space (MJS) of the nonoperative hip in female patients at 24 months post‐contralateral total hip arthroplasty (THA). This prospective cohort study was conducted from six to 24 months post‐THA. The subjects were 85 female patients with hip osteoarthritis (OA) who had undergone unilateral THA. The primary outcome was a change in MJS (ΔMJS). Daily step counts and moderate to vigorous physical activity were measured. To identify factors related to ΔMJS, a generalized linear model approach was used, with adjustment factors, Kellgren–Lawrence (KL) grade, PA, and interaction terms between PA and KL grade as explanatory variables. The interaction term between daily step count and KL grade was significant. The regression coefficient of the daily step count for ΔMJS was significant in the KL ≥ 1 group, but not in the KL = 0 group. A model with adjustment factors, an interaction term, and PA showed that the daily step count increased ΔMJS. PA was related to ΔMJS of the nonoperative hip in female patients with KL grade ≥1, but was not related to ΔMJS in patients without OA post‐THA. Excessive daily step count may be a risk factor for a decrease in MJS of the nonoperative hip.

AbstractLinear N‐substituted polyacrylamides bearing tricarboxylic moieties pendant to the backbone are synthesized, and coordinative binding approach is developed to convert them into Gd3+/Eu3+‐metallopolymers. Inner‐sphere coordination of the lanthanide ions with the pendant chelating moieties, together with their outer‐sphere stabilization by the randomly coiled backbone, are the reasons for peculiar water proton relaxation and luminescence properties of the metallopolymers obtained. Indeed, for Gd3+‐metallopolymer, the values of longitudinal and transverse relaxivity (r1 and r2) are 50 and 60 mm−1·s−1, respectively, while for the Eu3+‐counterpart, Eu3+‐centered luminescence is significantly raised compared to Eu3+ aquaions. Coil‐like conformation of the metallopolymer molecules undergoes a swelling at pH values above 5.0 as evidenced by transmission electron microscopy TEM and dynamic light scattering (DLS) data, which is followed by the changes in the Eu3+‐centered luminescence and r1(2)‐values of Gd3+/Eu3+‐metallopolymers. The phosphates additives (adenosine monophosphoric acid (AMP), adenosine diphosphoric acid (ADP), HPO42− and adenosine triphosphoric acid (ATP) induce well detectable changes in both water proton relaxation and luminescence of Gd3+/Eu3+‐metallopolymers. The luminescent changes distinguish AMP from the other phosphates, while the changes in water proton relaxation are greater for HPO42− and ATP compared to AMP and ADP. This study explains this by interplay of the effects associated with the formation of ternary phosphate‐lanthanide‐polymer complexes and stripping of lanthanide ions from the polymer molecules.

AbstractNanomedicines loaded in macrophages (MAs) can actively target tumors without dominantly relying on the enhanced permeability and retention (EPR) effect, making them effective for treating EPR‐deficient malignancies. Herein, copper‐crosslinked carbon dot clusters (CDCs) are synthesized with both photodynamic and chemodynamic functions to manipulate MAs, aiming to direct the MA‐mediated tumor targeting. First, green fluorescent CDs (g‐CDs) are prepared by a one‐step hydrothermal method. Subsequently, the g‐CDs are complexed with divalent copper ions to form copper‐crosslinked CDCs (g‐CDCs/Cu), which are incubated with MAs for their manipulation. Experimental results revealed that the prepared g‐CDCs/Cu displayed good aqueous dispersibility and fluorescent emission properties. The nanoassemblies can be activated to deplete the overexpressed glutathione (GSH) and generate reactive oxygen species (ROS) in the presence of laser irradiation through the combined Cu‐mediated chemodynamic therapy and CD‐mediated photodynamic therapy. Furthermore, the ROS produced in MAs enabled polarization of MAs to antitumor M1 phenotype, suggesting the future potential use to reverse the immunosuppressive tumor microenvironment. These results obtained from the current study suggest a significant potential to develop g‐CDCs/Cu for GSH depletion, ROS generation, and MA M1 polarization as a theransotic agent to tackle cancer.

Published: August 2024

AbstractObjectiveTreatment options for recurrent early glottic carcinoma's include conservative and radical surgical options. These options offer similar survival benefits with different impacts of patient's quality of life. We previously present our experience with vertical partial laryngectomy (VPL) and showed high locoregional control rates with high‐quality voice results and normal swallowing.Study DesignA long‐term retrospective review.SettingTertiary Care Center.MethodsWe analyzed all patients underwent VPL between the years 1995 to 2018. Long‐term oncologic and functional outcomes were collected.ResultsA total of 40 patients were included. The majority of whom were male (n = 38, 95%) with a mean age of 64.9 years (SD ± 9.5). With a median follow up time of 12 years (range 0‐24), 9 patients (22.5%) had disease recurrence; the majority of whom (8 patients), had local recurrence and all were salvaged with total laryngectomy. Eight patients (20%) developed second primaries in the head and neck region with a median time to diagnosis of 77 months (range 8‐227 months). Ten‐years overall survival, disease specific survival, and local disease‐free survival were 80%, 90%, and 80%, respectively. Five patients had postoperative laryngeal dysfunction with a total 10‐years laryngectomy free survival of 70%.ConclusionVPL has a sustainable oncologic outcome with a high long‐term laryngectomy free survival rate. This entity is an acceptable conservative salvage option for selected postradiated recurrent laryngeal squamous cell carcinoma patients.
Are public housing projects good for kids after all?
Authors: Han Jeehee , Schwartz Amy Ellen 
Published: August 2024

AbstractIs public housing bad for children? The net effect of moving into public housing on children's academic outcomes is theoretically ambiguous and likely to depend on changes to neighborhood and school characteristics. Drawing on detailed individual‐level longitudinal data on New York City public school students, we exploit plausibly random variation in the precise timing of entry into public housing to estimate credibly causal effects of public housing residency on academic outcomes. Both difference‐in‐differences and event study analyses suggest positive effects of public housing on test scores, with larger effects after the initial year. Stalled academic performance at entry may reflect disruptive effects of residential and school mobility. Effects on test scores are larger among students who move from lower‐income neighborhoods due, perhaps, to increases in neighborhood and school quality. For some subgroups, attendance improves and the incidence of obesity declines. Our results contradict the popular belief that public housing is bad for kids.

AbstractAimThis pilot examined the effect of online peer support on mental health problems among individuals with post‐acute sequelae of COVID‐2019 (PASC).MethodsA single‐arm pre‐post design of online peer‐support design consisting of eight sessions of 1 h per week with three to six participants and two facilitators per group was performed. Participants were recruited from online communities, social media, and medical clinics for the PASC between May and August 2023. The degrees of depression, anxiety, loneliness, social withdrawal, and self‐esteem were measured pre‐ and post‐intervention. Participants' statements during the sessions were analyzed using thematic analyses.ResultsOf the 18 participants, three dropped out of the interventions, and 17 (including two participants who dropped out) completed the pre‐ and post‐intervention questionnaires. Depression severity significantly decreased in the paired t‐test and linear mixed model. The following interactions were extracted: conveying the same feelings, dealing with difficulties, showing empathy, enhancing the atmosphere, and adapting to suit health conditions. Impressions extracted from participating in the interventions included feelings of emotional support, a sense of bonding, changes in perspective, changes in behaviors or new actions through participation, inadequacy during sessions, and adverse effects associated with participation.ConclusionOnline peer support may be helpful in treating depression in individuals with PASC.

Published: August 2024

ABSTRACTBackgroundThe association between opioid use and the risk of ventricular arrhythmias (VA) is poorly understood.AimsThe objective of this study was to synthesize the evidence on the risk of VA associated with opioid use.Materials & MethodsWe systematically searched the Cochrane Library, Embase, MEDLINE, and CINAHL databases in July 2022. Risk of bias was assessed using the Cochrane risk for bias tool for randomized controlled trials (RCTs) and ROBINS‐I for observational studies. Certainty of evidence was assessed using GRADE.ResultsWe included 15 studies (12 observational, 2 post hoc analyses of RCTs, 1 RCT). Most studies focused on opioid use for maintenance therapy (n = 9), comparing methadone to buprenorphine (n = 13), and reported QTc prolongation (n = 13). Six observational studies had a critical risk of bias, and one RCT was at high risk of bias. Two studies could not be included in the meta‐analysis as they reported a different outcome and studied an opioid antagonist. Meta‐analysis of 13 studies indicated that the use of methadone was associated with an increased risk of VA compared to the use of buprenorphine, morphine, placebo, or levacetylmethadol (risk ratio [RR], 2.39; 95% CI, 1.31–4.35; I2 = 60%). The pooled estimate varied greatly between observational studies (RR, 2.12; 95% CI, 1.15–3.91; I2 = 62%) and RCTs (RR, 14.09; 95% CI, 1.52–130.61; I2 = 0%), but both indicated an increased risk.ConclusionIn this systematic review and meta‐analysis, we found that methadone use is associated with more than twice the risk of VA compared to comparators. However, our findings should be interpreted cautiously given the limited quality of the available evidence.
