Published: March 2024

AbstractThe oxygen vacancies and surface oxygen species play pivotal roles in CO catalytic oxidation. In this study, Co3O4−CeO2 supported on resin based spherical activated carbon was fabricated and the effect of CeO2 on surface oxygen species was demonstrated through controlling various Ce contents. When Ce content was optimal (nCo : nCe=9), the maximum surface adsorbed oxygen content (60.3 %) is displayed and the catalyst achieved good CO conversion (T100=110 °C), water resistance and robust stability. DFT simulation calculation confirmed that the energy barriers of two transition states significantly decreased to 0.60 eV and 0.37 eV, respectively, with the addition of CeO2. The results indicate that the presence of CeO2 is conducive to the increasement of surface adsorbed oxygen content and optimal Co/Ce ratio is the most favorable for the CO oxidation. It is attributed to the visible decline of the energy barrier between oxygen vacancies and gas–phase oxygen at the Co3O4−CeO2 interface, and the process of oxygen vacancies replenishment could be more prone to occur at the interface. This study may provide a protocol for further improving surface species on supporting catalysts.

AbstractEnhancing the low‐potential capacity of anode materials is significant in boosting the operating voltage of full‐cells and constructing high energy‐density energy storage devices. Graphitic carbons exhibit outstanding low‐potential potassium storage performance, but show a low K+ diffusion kinetics. Herein, in&nbsp;situ defect engineering in graphitic nanocarbon is achieved by an atomic self‐activation strategy to boost the accessible low‐voltage insertion. Graphitic carbon layers grow on nanoscale‐nickel to form the graphitic nanosphere with short‐range ordered microcrystalline due to nickel graphitization catalyst. Meanwhile, the widely distributed K+ in the precursor induces the activation of surrounding carbon atoms to in situ generate carbon vacancies as channels. The graphite microcrystals with defect channels realize reversible K+ intercalation at low‐potential and accessible ion diffusion kinetics, contributing to high reversible capacity (209 mAh g−1 at 0.05 A g−1 under 0.8 V) and rate capacity (103.2 mAh g−1 at 1 A g−1). The full‐cell with Prussian blue cathode and graphitic nanocarbon anode maintains an obvious working platform at ca. 3.0 V. This work provides a strategy for the in situ design of carbon anode materials and gives insights into the potassium storage mechanism at low‐potential for high‐performance full‐cells.

AbstractThe article shows the outstanding properties and luminescence ability of Eu3+/Dy3+ co–doped BaMoO4 (BMED) materials, which have been successfully fabricated by the hydrothermal method. The crystalline structure analysis of BMED nanophosphor by X–ray diffraction (XRD) shows that it has a structure single–phase structure, with tetragonal BaMoO4 (JCPDS 029–0193), consist of spherical nanoparticles with a size diameter of 31.79–52.99 nm. The characteristic vibrational modes of molybdate lattice in the Raman spectroscopy confirmed the successful Eu3+/Dy3+ co–doped into the host matrix. The field emission scanning electron microscopy (FE–SEM) image shows that the BMED consists of quite uniform nanoparticle with sizes less than 50 nm. The energy dispersive spectra (EDS) confirm the purity and uniform distribution of elements Eu, Dy, Mo, O, Ba throughout in the solid sample. The BMED nanophosphor has is small bandgap from 2.83 to 3.00 eV. The photoluminescence spectra show that BMED have strong red emission at 616 nm of the transition (5D0 → 7F2) with luminescence lifetime from 0.330 to 1.429 ms. The BMED nanophosphor have potential application for the production of warm wLEDs, agricultural lighting and biomedical marking.

Published: March 2024

AbstractOvarian dermoid cyst is characterised by the presence of hair follicles, sebaceous glands grossly observed as clusters of matted hair in greyish cheesy material in the vicinity of ovaries. Upon examination of 235 buffalo genitalia, five were found to have abnormal ovarian texture and were relatively large in size. Further investigation revealed presence of dermoid cyst in these ovaries. Histopathological analysis showed degenerated primary, secondary and tertiary/Graafian follicles in the ovarian parenchyma, with patches of neuro‐ectodermal rosette‐like structures composed of glial cells. Other extra‐gonadal tissues often less organised were also observed like cartilage, fibrous connective tissue and glandular structures. In two of the specimens, corpus luteum with degenerated luteal cells was also present in the parenchyma of the ovary. These detailed investigations pointed to the infertility problems in buffaloes associated with this condition and often dictated in slaughterhouse‐derived ovaries. It has clinical significance as these structures are often confused with cystic ovarian disease upon rectal palpation, and treatment is unsuccessful in reducing the size of the ovary at the field level.

Published: March 2024

AbstractObjectivesThis review aims to evaluate the utility of nonmedicated middle meatal packing compared to no packing on synechia formation up to 12 weeks after endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS).MethodsWe conducted a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. A literature search was performed on Medline (PubMed), EBSCO CINAHL plus, CENTRAL, and Clinicaltrials.org and included randomized controlled trials in the English language only. We extracted all relevant data and conducted quality assessment using the Cochrane risk of Bias tool (version 2). We also performed the quality assessment of the outcomes using Grading of Recommendations Assessment, Development and Evaluation.ResultsOur search identified 390 articles of which four met our eligibility criteria. A total of 139 patients were randomized to receive middle meatal pack in either of the nostrils. At 4 weeks of follow‐up, there was no difference in the risk of synechia formation on either the packed side or the unpacked side, with a relative risk (RR) of 0.77 (95% confidence interval [CI]: 0.48–1.25). Similarly, no difference was seen at either 8–12 weeks of follow‐up, with an RR of 0.68 (95% CI: 0.42–1.20). Nasal congestion was reported to be less on the packed side on the follow‐up in one of the trials.ConclusionsOur systematic review, with limited evidence, indicates no difference in synechia formation between the nonmedicated packed and unpacked middle meatus at four and eight or 12 weeks after ESS for CRS. Further studies are required to ascertain the true effect of packing the middle meatus with different materials and its long‐term sequelae.

AbstractObjectivesHospital‐acquired catheter‐associated urinary tract infections (UTIs) have been regarded as preventable adverse events, yet their risk in endoscopic skull base surgery (ESBS) has not been well described despite common use. We determine the incidence of UTI following ESBS and identify contributing clinical factors.MethodsRetrospective review was conducted for a cohort of 229 consecutive adult patients who underwent endoscopic endonasal surgery for treatment of any skull base pathology between July 2018 and June 2022 at a tertiary academic skull base surgery program. Postoperative UTI comprised the primary outcome. Independent variables included patient demographics, use and length of urinary catheterization, and pre‐existing genitourinary conditions.ResultsNosocomial UTIs were identified in 1.3% (3/229) of patients, occurring on postoperative days 2, 9, and 14, respectively; all were catheter‐associated. Overall, 86.0% (197/229) of patients received urinary catheters (mean duration 2.2 ± 1.8 days). Compared to those without, patients with UTI were older (70.0 ± 15.4 vs. 52.2 ± 16.8 years, p = 0.034), had lengthier stays (94.7 ± 126.8 vs. 5.9 ± 8.4 days, p < 0.001), and had prolonged catheterizations (9.3 ± 5.5 vs. 2.1 ± 1.5 days, p < 0.001). Preoperative genitourinary conditions were also associated with UTI development, namely, chronic urinary retention/obstruction (66.7% vs. 4.0%, p = 0.006), urinary incontinence (66.7% vs. 6.2%, p = 0.013), prostate disease (100.0% vs. 17.8%, p = 0.035), and renal dysfunction (100.0% vs. 9.7%, p = 0.001). Among intraoperative cerebrospinal fluid leak patients, postoperative CSF leak incidence was not associated with catheter use versus nonuse (3.3% vs. 12.5%, p = 0.276).ConclusionAlthough UTIs are uncommon in ESBS patients, advanced age, length of stay, duration of indwelling urinary catheterization, and comorbid genitourinary conditions may elevate risk.

Abstract
Background
French Guiana (FG) is a French territory located in South America with the highest rate of armed assaults. FG presents a poorly developed road system and a young and precarious population that makes the geographical and socio-demographic characteristics specific. No data concerning the firearm injury management are available in this country. Studying thesis trauma could permit to improve the management of victims. The objective of this study is to investigate the epidemiology of firearm injuries in FG, to define characteristics of the victims, and to assess factors associated with death. These identified factors could enable target primary prevention and intensification of medical management.

Methods
From January 2016 to December 2019, we conducted a retrospective study at the Cayenne General Hospital (CGH), including all patients admitted for firearm injuries in the emergency department, the medical emergency and resuscitation service, and the forensic service. A bivariate analysis was performed to assess relevant clinical data that were entered into a logistic regression model to assess factors associated with death.

Results
A total of 871 files were analyzed concerning 340 patients included after cross-checking. Victims were mainly males (90%) and young (30 ± 11 years old). The injury occurred mainly at night (60%), in a context of assaults (83%) and with long-barreled guns (82%). Among the 290 patients managed at the CGH, 60% were hospitalized including 12% that were in the intensive care unit, 41% that required surgical treatment, and 7% that died in hospital. The overall average length of stay was 10 ± 18 days. Overall mortality (n = 71, 21%) is statistically associated with male gender (p = 0.007) and suicide context (p < 0.001). In multivariate analysis, the sites of wounds (head and neck, thorax; p < 0.001) as well as induced organ injuries (neurological, respiratory, and vascular; p < 0.005) were independent factors associated to mortality.

Conclusions
This work underlines the high incidence of ballistic trauma in FG. This mainly involves a young and male population linked to the use of long arms and assaults. Despite the geographical difficulties of the territory and the technical platform deficits (no neurosurgery, no cardiothoracic surgery, no interventional radiology), the mortality is comparable to other studies, but remains more than twice as high as in mainland France. Finally, despite a change in legislation restricting access to firearms, our results show that gunshot firearm injuries remain a major public health concern requiring greater political actions.

Zusammenfassung
Hintergrund
Urogenitale Tumoren zählen zur den häufigsten soliden Malignomen nach Nierentransplantation (NTX).

Fragestellung
Es erfolgte die Erfassung von Inzidenz und Mortalität urogenitaler Tumoren nach NTX im eigenen Patientengut und die Übertragung der Erkenntnisse in Bezug auf empfohlene Nachsorgenotwendigkeit und -frequenz.

Material und Methode
Durchführung einer retrospektiven monozentrischen Erfassung von Tumorerkrankungen allgemein und Urogenitaltumoren spezifisch von Patienten, die zwischen 2010 bis 2020 eine Nierentransplantation am Transplantationszentrum Dresden erhalten haben. Daraus wurden Handlungsempfehlungen für die Praxis als Nachsorgekonzept abgeleitet.

Ergebnisse
Insgesamt 13 % (93/710) der nierentransplantierten Patienten entwickelten eine Neoplasie. Patienten mit einem höheren Alter (60,1 ± 10,6 vs. 53,8 ± 12,5 Jahre; p < 0,001), einem erhöhten Charlson-Score (≥ 4: 68 % vs. 46 %; p < 0,001) und einer früheren Tumoranamnese (18 % vs. 8 %; p < 0,001) wiesen häufiger eine Tumordiagnose nach Transplantation auf. In der multivariaten Analyse zeigte sich dabei die frühere Tumoranamnese als unabhängiger Prädiktor für eine Tumorentwicklung nach Transplantation (OR 2,2; 95 %-KI [1,2–4,1]; p = 0,01). Von allen Tumorerkrankungen entfielen 30 % (28/93) auf urogenitale Tumoren. Am häufigsten dabei war die Entwicklung eines Nierenzellkarzinoms der Nativnieren (n = 12), am zweithäufigsten Prostatakarzinome (n = 9).

Schlussfolgerung
Urogenitale Tumoren bilden einen Großteil solider Malignome nach NTX. Aufgrund der Häufigkeit besteht die dringende Notwendigkeit einer dauerhaften Nachsorge sowie der spezialisierten urologischen Therapie. Bereits vor Listung zur Transplantation können Risikofaktoren erkannt und individuelle Konzepte zur Nachbetreuung erstellt werden.

Embedding Arbitrary Boolean Circuits into Fungal Automata
Authors: Modanese Augusto , Worsch Thomas 
Published: March 2024

AbstractFungal automata are a variation of the two-dimensional sandpile automaton of Bak et al. (Phys Rev Lett 59(4):381–384, 1987. https://doi.org/10.1103/PhysRevLett.59.381). In each step toppling cells emit grains only to some of their neighbors chosen according to a specific update sequence. We show how to embed any Boolean circuit into the initial configuration of a fungal automaton with update sequence HV. In particular we give a constructor that, given the description B of a circuit, computes the states of all cells in the finite support of the embedding configuration in $$O(\log \left| {B}\right| )$$

Published: March 2024

AbstractNowadays, a healthier and more sustainable lifestyle is the subject of much research. One example is the use of crossover trials to investigate the uptake of proteins, usually from alternatives to animal-based sources, by healthy volunteers. The data analysis is complex and requires many decisions on the part of the scientists involved. Such a process can be streamlined and made more objective and reproducible through bespoke software. This paper describes such a software package, $$\textbf{aaresponse}$$
aaresponse
, for the $$\textsf{R}$$
R
environment, available as open source. It features ample visualization functions, supports consistent curation strategies, and compares amino acid uptake of different protein meals (interventions) through the use of mixed models analysing parameters of interest like the area under the curve (AUC). The defining feature is the use of parametric curves to fit the amino acid levels over time, increasing the robustness of the approach and allowing for more strict quality control strategies.

Abstract
Introduction
Denosumab, a fully human anti-RANKL monoclonal antibody, is a widely used osteoporosis treatment that is increasingly being used in patients undergoing dialysis; however, its long-term efficacy and safety in these patients remain unknown.

Materials and methods
This observational study comprised individuals aged ≥ 20 years undergoing hemodialysis and receiving denosumab. After denosumab administration, we analyzed the long-term changes in bone mineral density (BMD) and levels of bone turnover markers (BTMs) and calcium.

Results
The study included 45 patients who have been receiving denosumab for a median duration of 3.8 (interquartile range, 2.5–6.7) years. Tartrate-resistant acid phosphatase 5b (TRACP-5b) levels decreased from a median of 595 (434–778) mU/dL at baseline to 200 (141–430) mU/dL after 6 months of denosumab administration (P < 0.001) and remained low thereafter. Similarly, bone-specific alkaline phosphatase (BAP) levels decreased from a median of 18.2 (15.9–25.8) μg/L at baseline to 12.4 (9.9–15.6) μg/L after 6 months (P < 0.001) and remained low thereafter. Meanwhile, BMD, as assessed with dual energy X-ray absorptiometry and measured at the distal 1/3 of the radius, did not decrease (0.465 ± 0.112 g/cm2 at baseline vs. 0.464 ± 0.112 g/cm2 after administration; P = 0.616). Regarding hypocalcemia, corrected calcium levels reached were the lowest at 7 days after administration and normalized within 30 days.

Conclusion
The study showed long-term suppression of TRACP-5b and BAP levels and sustaining BMD after denosumab administration over an extended period in patients undergoing hemodialysis.

AbstractThe district of Arauca is the second-largest producer of cacao in Colombia. However, despite its quality, it faces issues for export due to levels of cadmium (Cd) higher than the regulatory thresholds. A central question is how it may impact agricultural performance in the presence of Cd in cacao and chocolates. This study quantified Cd in cacao plantations from Arauca. Thus, 180 farms were assessed in the municipalities of Arauquita, Fortul, Saravena, and Tame. Five sample types (soil, irrigation channel sediment, soil litter, cacao seeds, and chocolates) were assessed for Cd. As a technological innovation, the new MXRF technology was used for Cd in chocolates. The sequence of Cd content was soil litter > chocolate > soils > cacao seeds > irrigation-channel sediment. A gradient north–south of Cd content in soil was observed, where highest content was found in farms near the Arauca River, and lower farther away. In irrigation channel sediment, Cd levels averaged 0.07 mg kg−1. The Cd content in cacao seeds was 0.78 mg kg−1 on average. Cd content in chocolates was above the threshold (1.10 mg kg−1 on average, including several cacao mass percentages). These artisanal chocolate bars produced by single farms were near the limit of Cd set by the European Union (up to 0.8 mg kg−1). Therefore, mixing beans from different farms could reduce their Cd content. The present study underscores the complexity of Cd distribution, emphasizing the importance of integrating soil, crop, and landscape features in managing and mitigating Cd levels in cacao.

AbstractThree new dinuclear triple helicates were synthesised using a ditopic semi-rigid pyridylylimine ligand L, separated by a diphenoxy-biphenol spacer providing considerable length to the backbone. L and the new large dinuclear triple helicate complexes [Fe2L3](BF4)4 (1), [Ni2L3](BF4)4 (2) and [Zn2L3](BF4)4 (3) have been characterised in solution and solid state. Single crystal X-ray diffraction was used to investigate overall complex ion shape as the coordination sphere was modulated by metal ion selection. Small differences in complex shape were seen to arise due to subtle distortions in coordination sphere environments. This study sheds light on how the length and twist of dinuclear triple helicates can be tuned by selection of coordinating metal ion.

Published: March 2024

AbstractWe present an economic and straightforward method to introduce 13C-19F spin systems into the deuterated aromatic side chains of phenylalanine as reporters for various protein NMR applications. The method is based on the synthesis of [4-13C, 2,3,5,6-2H4] 4-fluorophenylalanine from the commercially available isotope sources [2-13C] acetone and deuterium oxide. This compound is readily metabolized by standard Escherichia coli overexpression in a glyphosate-containing minimal medium, which results in high incorporation rates in the corresponding target proteins.
