Experiences of UK Clinical Scientists (Physical Sciences modality) with their regulator, the Health and Care Professions Council: Results of a 2022 survey
Authors: McJury Mark 
Published: September 2023

Abstract
Background: In healthcare, regulation of professions is an important tool to protect the public. Professions find themselves increasingly under scrutiny, and regulators wield considerable power over registrants.
In recent years, there has been considerable public concern with regulator performance. In the literature, there is no data on the experiences of Clinical Scientists with their regulator, the Health and Care Professions Council.
This article reports the findings of a survey from Clinical Scientists (Physical science modality) about their experiences with their regulator the Health and Care Professions Council, and their perception of the quality and safety of that regulation.
Methods: Between July-October 2022, a survey was conducted via the Medical Physics and Engineering mail-base, open to all medical physicists & engineers. Questions covered typical topics of registration, communication, audit and fitness to practice. The questionnaire consisted of open and closed questions. Likert scoring, and thematic analysis were used to assess the quantitative and qualitative data.
Results: Of 146 responses recorded, analysis was based on 143 respondents. Overall survey sentiment was negative in terms of regulator performance (negative responses 159; positive 106; significant at p < 0.001). Continuous Professional Development audit was rated median 4; other topics were rated as neutral (fitness to practice, policies & procedures); and some as poor (value).
Conclusions: The Clinical Scientist (Physical Sciences) profession rates the performance of the regulator negatively which conflicts with other assessments (such as those by the Professional Standards Authority). Survey respondents suggested a variety of performance aspects, such as communication and fitness to practice, would benefit from improvement. Indications from this small dataset, suggest a larger survey of HCPC registrants would be useful.

Abstract

With the emergence of new competitors in today's globalizing world and the increase in investments in telecommunication services in an environment where change continues, the importance of marketing strategies and the conscious behavior of customers have become an important demand for companies. New regulations and technologies increase competition among mobile operators. Because acquiring a new customer is more expensive than acquiring active customers, companies seek solutions to reduce the churn rate. Therefore, telecommunications companies want to analyze the concept of the customer's desire to change the service provider and take the necessary measures to protect their existing customers. In this study, usage information, usage trends, subscription commitment, subscription age, ARPU (average revenue per user) and billing information, competitor familiarity, outgoing call information, number porting experience, etc. Loss estimation modeling was made taking into account the The data set includes 593 columns and 1826588 lines. Corporate mobile customers were analyzed by dividing into three subgroups as Single Line Mobile Customers, 2-5 Line Mobile Customers, and 6-15 Line Mobile Customers. In order to estimate customer loss, various data mining analyzes were made with machine learning techniques in the SAS application. Four different machine learning methods were used while creating loss prediction models. The machine learning methods used are random forest, logistic regression, decision tree, gradient boosting. The model was developed by modeling with 600 different variables and loss estimation was made. ROC curves and lift chart results for different corporate mobile customer groups were compared and the most suitable models were selected for each group. In this project, it is aimed to prevent loss of revenue for different corporate mobile segment groups by estimating potential customer losses.
Softening Effect in the Heat-Affected Zone of Laser-Welded Joints of High-Strength Low-Alloyed steels
Authors: Frátrik Martin , Mičian Miloš , Brůna Marek 
Published: September 2023

Abstract
The softening effect, which occurs as an undesirable consequence of microstructural changes in the heat affected zone (HAZ) as a result of the welding process, is an inherent aspect of welding high-strength low-alloyed (HSLA) steels. One of the recommended ways to minimize these changes is the application of laser beam welding (LBW) as a lower heat input technology. Hence, this work compares and investigates the effects of laser beam welding on the properties of weld joints made of the steels S690QL, S960QL, S1100QL, S700MC, S960MC, and S1100MC. The main objective of this work is to examine the variations in the mechanical properties, grain size, and microstructure of the HAZ of different structural materials welded under various conditions. For laser-welded HSLA steels, the results showed no significant changes in the weld joint properties when the heat input was increased. When individual steels are compared, more obvious changes in the softening effect, grain growth, and the extent of the coarse-grain HAZ (CGHAZ) are evident. According to measured values it has been demonstrated that as the amount of Nb, V, and Ti in material decreases, the grain size in the coarse-grain HAZ (CGHAZ) and the zones’ overall width increases. It was also further demonstrated that the Cr and Mo content had a significant impact on the weld metal's hardness in laser-welded weld joints. These variations can be explained by the initial microstructure and the different chemical composition, which have an impact on the softening characteristics, austenitic grain growth, and the size of the CGHAZ.

Published: September 2023

Abstract

Background: The purpose of this study was to construct a clinical medication pathway for children with tic disorder (TD) and provide a reference for rational drug use for children with TD.
Methods: A literature review was conducted to develop an initial clinical medication pathway. Next, a two-round Delphi survey was conducted via a WeChat group. Experts were invited to rate the importance of each item on a 5-point Likert scale. The response rate, authority of the experts, coefficient of variation, and Kendall’s W were also calculated.
Results: In total, 26 experts from medical institutions in Sichuan Province were included in the Delphi survey. After two rounds of expert consultation, a clinical medication pathway was constructed that included 41 items in eight categories. These categories were: participants in clinical medication management, TD assessment, comorbidities assessment, treatment objectives and plans, tic drug treatment, comorbid attention-deficit hyperactivity disorder (ADHD) medication treatment, recurrence and referral management, and medication compliance management.
Conclusion: This study actively explored clinical medication pathways for children with TD in China and provided a standardized and highly operable medication pathway for reference in clinical practice. This pathway is expected to be widely used in treatment for children with TD. We suggest that further research should update and improve the clinical medication pathway using the latest evidence.

Published: September 2023

Abstract
Background: One of the most important challenges to global public health is antimicrobial resistance. The risk factors for antimicrobial resistant in severe pneumonia are constantly growing. This study aimed to identify risk factors forantimicrobial resistance and conduct a survival analysis of severe pneumonia patients with single and multiple pathogen.
Methods: This retrospective study collected secondary data from severe pneumonia patients admitted to the intensive care unit (ICU) at Cipto Mangunkusumo Indonesia National Referral Hospital from January 2016 to December 2022. Respiratory specimens were collected via bronchial washing. Univariate and multivariate analysis was performed to analyze risk factors for antimicrobial resistance. Kaplan‒Meier survival curves were generated with the log-rank test to compare 30-day mortality between patients infected with single and multiple pathogen.
Results: A total of 333 patients from 415 patients enrolled in this study were analyzed. Klebsiella pneumoniae (29%), Acinetobacter baumannii (24%) and Pseudomonas aeruginosa (12%) were the most frequently isolated pathogens. Risk factors for resistance to aminoglycoside, carbapenem, and quinolone are sepsis, cerebrovascular disease and ventilator-associated-pneumonia (VAP) (P<0.05). The Kaplan-Meier curves revealed that multiple pathogen influenced the survival rate of severe pneumonia patients (P<0.05).
Conclusions : Sepsis, cerebrovascular disease, and VAP were associated with antimicrobial resistance in severe pneumonia patients. The survival rate of severe pneumonia patients infected with multiple pathogen is low. This suggests the importance of further awarness of empirical antibiotic stewardship and mortality assessment in severe pneumonia patients.

Published: September 2023

Abstract

Development of effective methods for analyzing hypochlorite is of great significance due to the crucial role of hypochlorite in live organisms, as an endogenously produced reactive oxygen specie (ROS) in the human immune system. In this paper a novel fluorescent probe based on 6-methylthiocoumarinyl formate was designed and synthesized in one step for detection of hypochlorite in MeCN/PBS (8:2, v/v, pH 7.4) medium. The probe showed high specificity for hypochlorite over other competitive ROS analytes, extreme large Stokes shift of 265 nm, rapid response to hypochlorite within 20 s, low detection limit of 1.57 µM, and a wide applicable range of pH 3−10. The sensing mechanism was demonstrated to be based on oxidation of methyl phenyl sulfide to sulfoxide by hypochlorite. The probe may have extensive application for selective and convenient detection of hypochlorite due to its multiple advantages.

Abstract

Insects have developed a variety of sex-determining regulatory mechanisms throughout their evolution. In this study, we analyzed differentially expressed genes (DEG) from the ovary and testis transcriptomes ofAthetis dissimilis. A total of 11065 differentially expressed genes (DEGs) between the males and females were identified, of which 6685 genes were up-regulated and 4380 genes were down-regulated in females. AAdistra-2(525 bp) gene was obtained from the transcriptome ofA. dissimilis, and sequence alignment with other related species revealed a highly conserved RRM domain. Phylogenetic analysis showed that the Adistra-2 protein is a close relative of the lepidopterous tra-2 protein. The qRT-PCR of theAdistra-2temporal and spatial expression pattern showed that it is more abundant during embryonic development than other stages, and its expression was higher in ovaries than in testes. This work provides a theoretical reference for the sex differentiation and genetic manipulation of this insect.
Downregulating of hsa-miR-143-3p induced by low fluid shear stress promotes chondrocyte proliferation and extracellular matrix secretion by promoting ERK5/KLF4 signal pathway
Authors: Zhao Jun , Xia Yayi 
Published: September 2023

Abstract
Objective
Low fluid shear stress (FSS, ≤2dyn/cm2) can protect chondrocytes. Despite this, the function of miRNA in FSS-induced chondrocyte proliferation, maintenance of extracellular matrix stability and the potential molecular mechanism remains is still unknown. The intention of this research was to examine whether hsa-miR-143-3p played a defensive effect on chondrocytes after loading FSS and its related molecular mechanism.
Materials and methods
The level of hsa-miR-143-3p was examined by qRT-PCR. The expressions of ERK5, phosphorylated ERK5 and KLF4 were detected by Western blot. Double luciferase reporter gene assay was utilized to confirm the target gene of hsa-miR-143-3p. proliferation of cells was analyzed with CCK-8 method and EdU method. The ability of chondrocytes to secrete extracellular matrix was detected by type II collagen immunohistochemical staining and toluidine blue staining methods.
Results
When SW1353 cells were exposed to low FSS (1.8 dyn/cm2,60 min), hsa-miR-143-3p was reduced. Then we confirmed the increase of hsa-miR-143-3p inhibited the proliferation of chondrocytes, the secretion of type II collagen and proteoglycan within extracellular matrix. Besides, FSS promoted extracellular matrix secretion and chondrocyte proliferation through down-regulating hsa-miR-143-3p. Double luciferase reporter gene assay revealed ERK5 was a direct target of hsa-miR-143-3p. QRT-PCR and Western blotting methods confirmed hsa-miR-143-3p targeted ERK5/KLF4 signal pathway to promote cell proliferation and maintain extracellular matrix stability.
Conclusion
This research shows the downregulation of hsa-miR-143-3p induced by low FSS promotes the proliferation of chondrocytes, the secretion of type II collagen and proteoglycan of cartilage by activating ERK5/KLF4 signal pathway. These findings may provide a new molecular mechanism for moderate mechanical stimulation to protect cartilage.

Published: September 2023

Abstract
This study investigates antenna performance based on its manufacturing process. Two types of planar antennas are manufactured on FR-4 dielectric using three different techniques: traditional lithography, laser ablation, and the novel SSAIL (selective surface activation by laser) technique. Various characteristics, such as reflection coefficient, gain, half-power beamwidth, and surface conductivity, are measured to compare the results. These findings can provide valuable guidelines for selecting an optimal antenna manufacturing technique. In both types of antennas, the highest gain is achieved using laser ablation, with the slot loaded patch antenna reaching 8.5 dBi and the Yagi-Uda antenna reaching 9.76 dBi. Antennas manufactured using SSAIL technology are notable for their great resolution and usefulness in constructing structures on non-metallized dielectrics.

Abstract
Objectives. To describe electronic cigarette (e-cigarette) usage behaviors, beliefs, and spirometry patterns in people with HIV (PWH) who smoke tobacco cigarettes.Design: Cross-sectional, observational, pilot study conducted in an HIV care center in the Bronx, New York.Methods Enrolled PWH who confirmed tobacco cigarette usage completed an audio computer-assisted self-interview and spirometry. Because a minority of PWH tobacco users have ever used e-cigarettes, we purposely oversampled current and past e-cigarette users.Results We enrolled 42 participants into the study. Of these, 19 were current e-cigarette users, 13 were past users, and 10 were never users. Current and past e-cigarette users were significantly younger than never users, and they were more likely to have ever used other tobacco products (mostly pipes and cigars). There were no significant differences in tobacco smoking frequency, daily cigarette consumption, nicotine dependence, or motivation to quit between e-cigarette users and non-users. Current and past users were less likely to demonstrate an obstructive pattern on spirometry than never users. Current e-cigarette users cited assistance in attempting to quit tobacco cigarettes as the most common reason for their use. Our sample used eight different vaping devices and most commonly used tobacco/nicotine as their vaping substrate.Conclusions PWH tobacco cigarette smokers who use e-cigarettes most commonly vape tobacco/nicotine products. Current e-cigarette users did not smoke fewer tobacco cigarettes per day than non-users. The observation that those who had never used e-cigarettes were more likely to demonstrate obstruction on spirometry was surprising and may merit further investigation.

Abstract
Entoloma clypeatum is an edible ectomycorrhizal fungus that is often symbiotic with Rosaceae fruit trees. Malus domestica is one of the main economic fruit trees in China. The symbiotic culture of E. clypeatum and M. domestica rootstock, Malus robusta for mycorrhizal synthesis was carried out. The mycorrhizal infection rate, biomass, chlorophyll content, photosynthetic index, plant hormone content, antioxidant enzyme activity and osmotic adjustment substance content of mycorrhizal seedlings and non-mycorrhizal seedlings seedlings were determined by morphological observation of mycorrhizal roots. The effects of E. clypeatum on symbiotic plants were expounded, which provided a basis for further research and application of the fungus. The results showed that E. clypeatum and M. robusta could form cylindrical or clavate mycorrhizal (52.5%), which could increase the biomass of symbiotic plants. The chlorophyll content increased by 95.4% compared with the control group, which improved the photosynthesis of seedlings. The contents of ZT, IAA and GA3 in roots, stems and leaves of plants were significantly higher than those in the uninoculated group (30.7%-186.45%), ABA content decreased (11.5-76.2%), antioxidant enzyme content increased (13.1%-111.5%), soluble protein, soluble sugar and free proline content increased, and malondialdehyde content decreased. The results showed that E. clypeatum had a positive effect on the growth of M. robusta and could enhance its adaptability and stress resistance. This also lays a foundation for the development and application of E. clypeatum and promotes the development of fruit tree industry, and provides a reference for the study of ectomycorrhizal fungi.

Published: September 2023

Abstract

Cross-laminated timber (CLT) is increasingly used as shear walls in timber structures due to its excellent structural properties, fire resistance, dimension stability, carbon sequestration capabilities, and energy efficiency, but the effectiveness of this material for airborne sound insulation has received little attention. Here, airborne sound insulation was tested for nine full-scale CLT walls. The impacts of half-lap joints, CLT thickness, and CLT composite wall with gypsum board (GB) and light frame cladding were determined. Single number indexes and weighted sound reduction index (Rw) values were calculated. The results revealed that half-lap joints had no impact on sound insulation of CLT bare wall. The 175 mm thick CLT and 105 mm thick CLT bare wall sheathed with GB and light wood frame exhibited slightly better airborne sound insulation than the 105 thick CLT bare wall, with an increase in Rw from 32 to 38 dB and change in sound insulation class from 3 to 4, but these materials do not meet the requirement for internal separation components in residential buildings. The CLT composite walls sheathed with stagger studs, light steel frame, damping coating, and deadening felt achieved Rw values ≥42 dB, leading to increases in airborne sound insulation class to levels 5 and 6. A simplified statistical energy analysis model was developed for the CLT composite wall system with a light frame and the predicted Rw values matched well with the experimental results.

Abstract

Although video recording is now a standard feature in smartphones and other digital devices, digital records are affordable and straightforward to take and distribute on social media. Furthermore, digital recordings have recently become an essential part of our daily lives, ranging from personal experiences to surveillance footage that may now be utilised as evidence of proof. Thus, it is essential to create detection algorithms for this kind of captured video because the number of high-standard counterfeit videos on social networks and other media is increasing exponentially. Evaluating the integrity of surveillance videos is crucial with the advanced equipment of surveillance systems. As a result, the rapid increase in surveillance cameras has made progress in physical security, including in building homes, stores, governmental buildings, agencies, etc. Moreover, surveillance videos have lately been extensively used as significant evidence in the courts. The evidence from the video can be crucial for a court of justice and investigators to comprehend the incidents as they happened. Unfortunately, due to the widespread of video editing programs, the video forgery/ tampering process has become incredibly simple. Consequently, the courts refuse to accept these videos as evidence because there is some margin of doubt about their authenticity and integrity. Therefore, to avoid such a situation in the future, more efforts are needed in video forensics. For this reason, this paper reviews primarily all the techniques and methods proposed so far to find out forgery in surveillance recordings and how the authenticity of such videos is proven.
