Published: May 2023

Abstract
Background Quality and performance measurement as part of quality improvement in healthcare is integral for service delivery and development. This is particularly pertinent for health services that deliver care in ways that differ from traditional practice. Community Emergency Medicine (CEM) is a novel and evolving concept of care delivered by services in parts of the UK and Ireland. This scoping review aims to provide a broad overview of how quality and performance may be measured within services delivering CEM.Methods and Analysis Methodology follows the Preferred Reporting Items for Systematic review and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) and is guided by recognised work of Arksey and O’Malley and the guidelines developed by the Joanna Briggs Institute. Several databases will be searched: Medline, Embase, Emcare, CINAHL, Scopus, the Cochrane library and grey literature. Search terms have been developed by representatives within Community Emergency Medicine services. Two reviewers will independently screen eligible studies for final study selection. Results will be collected and analysed in descriptive and tabular form to illustrate the breadth of measurement that may be applicable to CEM services. This scoping review protocol has been registered with the Open Science Framework platform (osf.io/e7qxg).Discussion This is the first stage of a larger research study aimed at developing national quality indicators for CEM. The purpose of this scoping review is provide a comprehensive review of quality measures that could be used within CEM. The results will be mapped using a framework and identify gaps in the literature to help guide future focused research.

Published: May 2023

Abstract
The present study demonstrates the feasibility of a constructed wetland (CW) planted with Phragmites australis to treat the heavy metals (HMs) from wastewater. Wastewater samples were collected from the in-let, out-let of the CW and analyzed for HMs such as Cadmium (Cd), Zinc (Zn), Lead (Pb), and Copper (Cu) using standard methods. Similarly, samples of Phragmites australis and sediments were also analyzed for selected HMs. Results indicate that the removal efficiencies of the planted CWs for Cd, Zn, Cu and Pb were 89.34, 76.27, 68.14, and 66.42%, respectively. On the other hand, the removal efficiency of the unplanted system was significantly lower, ranging between 18.27 and 33.16%. The plant played a strategic role in the absorption and accumulation of pollutants, the greatest mean concentrations of HMs were found in the below-ground plant parts of P. australis. While, the survey revealed that the amount of HMs accumulated in the aerial horizon represents often an only small adsorbed fraction, but higher than the concentrations measured at the underground horizon of the soil. The biological accumulation factor confirms the previous observations, that the roots and the rhizomes are the most bio-accumulator of all analyzed elements and, the results of the transfer factor values were estimating the ability of P. australis to transfer HMs from roots to sheets, which varied between 0.97 and 1.61 by the following order: Cd > Pb > Zn > Cu.

Abstract

Tomato (Solanum lycopersicum L.) is the second most important vegetable crop after potatoes, and global demands have been steadily increasing in recent years. Conventional breeding has been applied to breed and domesticate tomato varieties to meet the need for higher yield or superior agronomical traits that allow to sustain under different climatic conditions. In the current study, we applied bulk population breeding by crossing eight tomato accessions procured from the Asian Vegetable Research and Development Center (AVRDC) with three heat-resistant tomato inbred lines from Vietnam and generated ten elite tomato (ET) lines in the F8 generation. The individual F8 lines exhibited robust vigor and adaptability to Vietnamese climate conditions. Among the ten lines, ET1 and ET3 displayed indeterminate growth. ET2 showed semi-determinate, while all the other lines had determinate growth. The different ET lines showed distinctive superior agronomical traits, including early maturing (ET4, ET7, and ET10), highly efficient fruit set (ET1), higher yield (ET1, ET8, ET10), jointless pedicels (ET2), and partial parthenocarpy (ET9). Molecular analysis revealed that the ET3 line consisted of Ty-1 and Ty-3 loci that positively contribute to Tomato yellow leaf curl virus (TYCLV) resistance in tomato plants. The elite tomato lines developed in this study would contribute significantly to the Vietnamese and Asian gene pool for improved tomato production and may be a valuable resource for various breeding goals.

Abstract
On a global scale, breast cancer (BC) is the most prevalent malignancy among women. Triple-negative breast cancer (TNBC) is a subtype with a poor prognosis and high recurrence, metastasis, and mortality rates. Numerous studies have shown that the TAGLN gene participates in tumorigenesis and tumor invasion. However, TAGLN function in TNBC remains unknown. In this study, we screened 201 TNBC differential genes, including 133 up-regulated and 68 down-regulated genes. Gene Set Enrichment Analysis (GSEA) results showed that these differential genes were mainly enriched in DNA metabolic, nucleic acid binding biological process and gene expression, Rho GTPase, RHOBTB3, and cell cycle signaling pathways. Western blot indicated that TAGLN expression is lower in breast tissue than in normal tissue. However, the GSE38959 database showed that TAGLN is highly expressed in TNBC cells compared with mammary duct cells, and the CancerSEA database indicated that TAGLN is positively correlated with EMT, invasion, angiogenesis, differentiation, apoptosis, metastasis, proliferation, and stemness. Functionally, TAGLN promoted TNBC cell proliferation, migration, invasion, and cell cycle progression in vitro and tumor cell growth in vivo. Further mechanistic studies demonstrated that TAGLN promoted TNBC cell growth by regulating the AKT/CDK2 pathway. In sum, TAGLN is highly expressed in TNBC and promotes cell proliferation, migration, and invasion in vitro and tumor cell growth in vivo.

Published: May 2023

Abstract
The novelty of the proposed control approach lies in hybridization of control technique based on Nonsingular Terminal Sliding Mode (NTSM) Control, metaheuristic optimization algorithms and adaptive super-twisting based on Lyapunov stability analysis for controlling Quanser Aero simulator helicopter. Firstly, the he NTSM and NTSM Super Twisting (NTSTW) controllers are designed Followed by optimization of the designed controllers using Grey Wolf Optimizer (GWO), Whale Optimization Algorithm (WOA), Salp Swarm Algorithm (SSA) and Ant Lion Optimizer (ALO). Qualitative and quantitative comparisons between the obtained optimized controllers is then thoroughly analyzed. Results confirmed that the Optimized NTSTW (O-NTSTW) based on GWO demonstrated overperformance compared with other controllers. In order to achieve superior performance with robustness, this controller is hybridized with an adaptive Lyapunov super-twisting algorithm resulting in a new controller Adaptive O-NTSTW (AO-NTSTW). Visualization using ROS-Gazebo is done while validating AONTSTW and O-NTSTW.Simulation results demonstrated the effectiveness and the superiority of AO-NTSTW compared to O-NTSTW.

Abstract
Squamous cervical cancer (SCC) is a major cause of death in women, yet its molecular characteristics are poorly understood. Here, we profiled histopathological and molecular alterations in SCC, and used large language models (LLMs) for interpretation, reasoning, and understanding of multi-modal data. We implemented an immersive-knowledge prompting (iKLP) strategy to trigger LLMs, which interpreted 17.8%-20.3% of omic alterations known to be associated with cancer. Also, the emergence of cross-disciplinary reasoning in LLMs helped for interpreting phenotypic effects of SCC molecular alterations, exemplified by a prognostic biomarker HRG, and targetable kinases, CDK18 and CDK9. With experimental validations, LLM-reasoning showed >2-fold increased confidence for 68.5% of analyzed molecules. Strikingly, LLMs understood the information flow of cell-cell communications, and uncovered a CDK18-mediated immune escaping axis in orchestrating the crosstalk of malignant, immune, and niche cells. We anticipate that LLMs can be used for completely distinguishing between knowns and unknowns in any scientific problems.
Effects of Intimate Partner Violence and Childhood Trauma on Depression in Ghanaian Women: A Cross-sectional Study
Authors: Longla Terence Acheliu , Ogum-Alangea Deda , Hal Guido Van 
Published: May 2023

Abstract

Background: Intimate partner violence (IPV) and childhood trauma are highly prevalent in sub-Saharan Africa (SSA), especially among women. These two traumatic experiences can adversely affect the physical and mental health status of the victims. One of the mental health consequences is major depressive disorder, a relatively neglected health issue in SSA. This study aims to examine the association between IPV and depression and determine if there is any significant interaction between IPV and childhood trauma as predictors of depression among Ghanaian women.
Methods: The current study is a secondary analysis of cross-sectional data obtained from 1877 women during the Ghana Community-Based Action Teams Study in the central region of Ghana between 2016-2019. The negative binomial regression model was used for univariable and multivariable analyses, and interaction plots were used to study interaction effects. The level of statistical significance was set at 0.05.
Results: Emotional violence was the most commonly reported form of IPV, with a prevalence of 24.6% (95% CI: 20.5-29.2). Regression analysis showed that after controlling for childhood trauma, age, income level, marital status, level of education, disability and pregnancy status, only emotional (coef. =1.038, 95%CI: 1.018– 1.058, p-value <0.001) and sexual (coef. =1.037, 95%CI: 1.022– 1.053, p-value <0.001) IPV were significant predictors of depression. Except for economic IPV, there was a statistically significant interaction effect between IPV and childhood trauma (coef. = 0.995, 95%CI: 0.992– 0.998, p-value=0.003).
Conclusion: Exposure to emotional and sexual IPV significantly predisposes women to develop depressive symptoms. There is a significant interaction effect between early and late-life trauma on the occurrence of depression. Public health interventions to reduce IPV and childhood trauma must be strengthened in addition to early case identification and support through screening.

Abstract

The recovery of CaCO3 from periwinkle shells as a precursor for the synthesis of CaO nanoparticles is validated in this work. The sol-gel synthesized CaO nanoparticles were characterized by XRD, FT-IR, UV visible spectrophotometer, SEM, BET and ICP instrumentation. Information obtained from the characterization showed that the material has a band gap of 4.12 eV, porosity in the mesoporous range (average pore size of 3.02 nm), crystalline size of 18 nm, BET surface area and pore volume of 220.11 m2/g and 8.43 cc/g respectively. The application of the nanoparticles for the separation of lead (II) from aqueous solution yielded results that indicated a strong dependency of the adsorption efficiency on decreasing temperature but increasing pH (up to 6.5), initial concentration of Pb2+, adsorbent dosage and period of contact. The interaction of concentration, time, temperature and adsorbent dosage indicated that optimum efficiency greater than 80% can be obtained at a temperature of 318 K, concentration of 250 ppm, an adsorbent dosage of 0.5 g and contact period of 75 minutes. Enhanced removal capacities (reaching almost 100% efficiency) were obtained under UV-activated adsorption experiments. The adsorbent showed an excellent ability to favourably adjust the pH, dissolved oxygen, alkalinity and conductivity of the contaminated water. It also displayed an appreciable tendency towards reusability and the total recovery of the adsorbed heavy metal ions from its surface. The pseudo-first-order kinetic, liquid film diffusion, Freundlich, Halsey and Elovich adsorption isotherms best fitted the adsorption process and confirmed the multimolecular adsorption layer with physical adsorption profile. Also, the adsorption of the heavy metal ions is limited by liquid film diffusion and supported surface heterogeneity and physical adsorption mechanism.
Coexistence of Crowned Dens Sign and Calcification of Ligamentum Flavum in the cervical Spine: coincidence or association?
Authors: Meng Yake , Pan Weicheng , Zhang Weihang , Zhang Wei , Pan Hao , Guo Yongfei 
Published: May 2023

Abstract
Background: Calcification of the cervical ligamentum flavum(CLF) and periodontoid calcification are two rare diseases in the orthopaedic clinic. Only few reports have described these coexisting conditions.
Objectives: We present our cases of cervical radiculomyelopathy caused by CLF combined with or without periodontoid calcification, and the relationship between the two clinical conditions are briefly discussed on the review of data of the literature.
Methods: We retrospectively reviewed 33 patients with CLF. In our case series, the clinical and radiological characteristics of patients are described and analyzed. The calcification surrounding the dens is termed as crowned dens sign(CDSign) in our study. And the relationship between the two conditions of CLF and CDSign are discussed.
Results:There were 28 women and 5 men aged between 56 and 86 years. Neurological symptoms and neck pain were presented in most patients. Calcification sites on axial CT images were described in 33 cases with 81 levels, C4-5 and C5-6 were attacked most frequently, and multiple- rather than single-level involvement could be observed in our series. CDSign was identified in 26 cases, and the the prevalence were 79%. Following evaluation, 23 patients received posterior surgery, and 8 patients underwent anterior cervical surgery.
Conclusions: The coexistence of CDSign and CLF is an uncommon phenomenon. The association of these two diseases is stronger than a coincidence. It is possible that the coexistence of CLF with CDSign may be a rare form of the cervical manifestation of calcium pyrophosphate dihydrate (CPPD) deposition disease.

Abstract
Background Tuberculosis continues to be a serious health problem, and drug-resistant tuberculosis is an increasing threat that directly impacts the tuberculosis control program. These can be prevented or controlled by combining several drugs with antituberculous activity. In the present study, an attempt is made to understand the combinatorial effect of two medicinal plant extracts i.e. Piper longum and Cressa cretica against Mycobacterium tuberculosis.Methodology 2D checkerboard assay was used to study the combinatorial effect of the crude extracts. The 2-∆∆Ct method was used to determine the changes in gene expression of selected genes rpoB, gyrA and gyrB involved in transcription and DNA replication and intrinsic resistance of Mycobacterium tuberculosis to front-line drugs.Results Determination of the effect on gene expression at the subminimum inhibitory concentration of the crude extracts. The required MIC concentration, 125 µg/ml, was inversely reduced up to 7 µg/ml for P. longum. Similarly, the required MIC concentration of 250µg/mL of C. cretica is reduced to 10µg/mL.Conclusions The relative change in gene expression for rpoB and gyrA was 2 and 4-fold, respectively, and 1-fold for gyrB. Further characterization of the downstream target genes and in vivo studies may provide the mode of action of these two anti-mycobacterial agents.
