AbstractBackground and AimOccupational injury is any personal injury that can lead to disease, disability, or death due to accidents sustained by workers while performing their work. The present study aimed to determine the prevalence of occupational injuries and associated factors among workers of textile and garment factories in Mekelle City, Northern Ethiopia during the era of COVID‐19.MethodsA cross‐ectional study was conducted among 348 Textile and Garment factories in Mekelle City, Northern Ethiopia on September and October 2020. Data were collected using a semi‐structured face‐to‐face interview questionnaire by trained data collectors and supervisors. Occupational injury was assessed by a yes/no question “Have you had any injury related to your occupation in the last 12 months?.” Epi Data version 3.1 was used to enter data and Statistical Package for Social Sciences (SPSS) version 23 was used for data analysis. A multivariable logistic regression model was used to determine the independent determinants of occupational injury, and variables with p < 0.05 were considered as statistically significant.ResultsThe annual prevalence rate of occupational injury among textile and garment factories was 27.8% (95% confidence interval [CI] = 23.2−32.9%). Factors like being a male (AOR = 3.65; 95% CI = 1.92−6.92), job satisfaction (AOR = 0.22; 95% CI = 0.11−0.43), sleeping disorder (AOR = 3.47; 95% CI = 1.91−6.32), job stress (AOR = 2.62; 95% CI = 1.44−4.73), and safety and health training (AOR = 0.40; 95% CI = 0.22−0.74) were significantly associated with the occurrence of occupational injury.ConclusionExpectedly, lockdown during COVID‐19 could lead to absenteeism and reduced prevalence of occupational injuries as the outcome of this study.

Published: March 2024

AbstractSome biomolecules involved in pathological calcification have been identified. However, the exact mechanism in which this intricate process occurs remains unknown. Extracellular DNA (exDNA) has recently been recognized as a partaker in this ectopic phenomenon. Extracellular DNA acts as an intercellular messenger that transmits information and orchestrates complex inflammatory responses. Changes in the morphology or function of exDNA may trigger calcification under pathological conditions. In the present review, recent advances on how DNA is released into the extracellular milieu to become exDNA will be highlighted in conjunction with how exDNA directly and indirectly contributes to the progression of pathological calcification. Emphasis is placed on the “gluing” effect of neutrophil extracellular traps that act as a bridge between inflammation and pathological calcification. Manipulation of exDNA may open new vistas for the development of enterprising strategies that prevent or treat pathological calcification.

Published: March 2024

AbstractInappropriate patient sexual behaviors (IPSBs) can negatively impact work performance, job satisfaction, and the psychological well‐being of clinicians and staff. Although the Veterans Health Administration (VHA) is the largest integrated healthcare system in the United States, the rate of IPSBs in VHA hospitals is unknown. The unique demographic and cultural characteristics of military populations may be associated with IPSBs. To evaluate the extent and impact of IPSBs within a large VA healthcare system (VAHS), a survey was disseminated to all staff. Among the 32% of staff who responded (N = 1359), over half (n = 789; 58.1%) of participants reported at least one instance of IPSB during the past year; this included 67.9% (n = 644) of staff who identified as women and 33.4% (n = 126) of staff who identified as men. There was a significantly greater impact of IPSBs for women, as compared to men, on psychological well‐being (X21 = 60.4, p < .001, odds ratio [OR] = 4.55, 95% confidence interval [CI]: [3.08, 6.79]), work satisfaction (X21 = 43.0, p < .001, OR = 3.51, 95% CI: [2.40, 5.18]), and workplace practices (X21 = 48.9, p < .001, OR = 4.02, 95% CI: [2.69, 6.11]). The results of this project highlight the need for overcoming barriers to reducing the pervasiveness and impact of these experiences.

Authors: Zhao Ziyu , Zhou Heng , Sun Qian (Chayn) 
Published: March 2024

AbstractJourney to crime describes the spatial patterns of offenders from their residential area to the crime location. When compared to other research topics regarding urban crime, there is still a lack of research on journey to crime, especially in China, as a result of which the behavioural motivation of offenders cannot be comprehensively examined. Four typical types of crimes committed against property (pickpocketing, robbery, theft and burglary) were investigated in the Nanguan District of Changchun from 2010 to 2016. The results showed significant effects of the demographic characteristics of offenders and spatiotemporal factors on the journey to crime. In terms of the place of household registration, offenders from the central urban districts of Changchun tend to commit short‐distance local robbery, whereas those from the suburban counties tend to commit long‐distance non‐local crimes. With increasing population density, the proportion of local plunders increases directly. This study aims to encourage urban managers to rethink the governance of floating populations, and assist police in strengthening social security.

BackgroundAcoustically activatable perfluoropropane droplets (PD) can be formulated from commercially available microbubble preparations. Diagnostic transthoracic ultrasound frequencies have resulted in acoustic activation (AA) predominately within myocardial infarct zones (IZ).ObjectiveWe hypothesized that the AA area following acute coronary ischemia/reperfusion (I/R) would selectively enhance the developing scar zone, and target bioeffects specifically to this region.MethodsWe administered intravenous PD in 36 rats and 20 pigs at various stages of myocardial scar formation (30 minutes, 1 day, and 7 days post I/R) to determine what effect infarct age had on the AA within the IZ. This was correlated with histology, myeloperoxidase activity, and tissue nitrite activity.ResultsThe degree of AA within the IZ in rats was not associated with collagen content, neutrophil infiltration, or infarct age. AA within 24 hours of I/R was associated with increased nitric oxide utilization selectively within the IZ (P < .05 compared with remote zone). The spatial extent of AA in pigs correlated with infarct size only when performed before sacrifice at 7 days (r = .74, P < .01).ConclusionsAcoustic activation of intravenous PD enhances the developing scar zone following I/R, and results in selective tissue nitric oxide utilization.
Technology paternalism: Development and validation of a measurement scale

Published: March 2024

AbstractAs technologies become smarter, they tend to protect their users, much like parents protect their children. However, caring too much about a user can lead to technology paternalism, a construct that is becoming increasingly relevant with the advent of smart technologies. Nonetheless, very little is known about what technology paternalism is or how it can be measured. The authors applied established procedures from scale development methodology followed by quantitative measurement to present and validate a three‐factor scale (limiting, overruling, and welfare). The approach offers first empirical evidence linking technology paternalism to associated concepts, showing that it correlates as expected with established constructs in the literature on technology acceptance. This study contributes to the literature by uncovering a construct of interest to a critical discussion of technology paternalism and by providing a measurement tool that can be used by researchers, policy makers, and managers.

Published: March 2024

AbstractThis paper presents the design and prototype development of a compact frequency‐selective surface (FSS) for shielding WLAN signals. The FSS unit‐cell geometry is evolved by modifying the arms of the conventional crossed dipole element. The footprint of the unit cell is only 6 mm × 6 mm × 1.6 mm. The proposed FSS offers stop band characteristics at 5 GHz for both transverse electric (TE) and transverse magnetic (TM) modes. In addition, the FSS offers angular stability up to 60°. A prototype of the proposed FSS is fabricated and measured to validate its simulations. Measured bandwidth of the stop band is 410 MHz, referenced at −20 dB for both TE and TM modes. Equivalent circuit model of the FSS is derived and the results are compared with the simulations.

AbstractPurposeTo understand how macromolecular content varies in the human brain with age in a large cohort of healthy subjects.MethodsIn‐vivo 1H‐MR spectra were acquired using ultra‐short TE STEAM at 7T in the posterior cingulate cortex. Macromolecular content was studied in 147 datasets from a cohort ranging in age from 19 to 89 y. Three fitting approaches were used to evaluate the macromolecular content: (1) a macromolecular resonances model developed for this study; (2) LCModel‐simulated macromolecules; and (3) a combination of measured and LCModel‐simulated macromolecules. The effect of age on the macromolecular content was investigated by considering age both as a continuous variable (i.e., linear regressions) and as a categorical variable (i.e., multiple comparisons among sub‐groups obtained by stratifying data according to age by decade).ResultsWhile weak age‐related effects were observed for macromolecular peaks at ˜0.9 (MM09), ˜1.2 (MM12), and ˜1.4 (MM14) ppm, moderate to strong effects were observed for peaks at ˜1.7 (MM17), and ˜2.0 (MM20) ppm. Significantly higher MM17 and MM20 content started from 30 to 40 y of age, while for MM09, MM12, and MM14, significantly higher content started from 60 to 70 y of age.ConclusionsOur findings provide insights into age‐related differences in macromolecular contents and strengthen the necessity of using age‐matched measured macromolecules during quantification.

Published: March 2024

AbstractDrug delivery systems, including liposomes, gels, prodrugs, and so forth, are used to enhance the tissue benefit of a pharmaceutical drug or conventional substance at a specific diseased site with little toxicological impact. Nanotechnology can be a rapidly developing multidisciplinary science that enables the production of polymers at the manometer scale for different medical applications. The use of biopolymers in drug delivery systems provides compatibility, biodegradability and low immunogenicity biologically. Large‐scale and smaller‐than‐expected medication particles can be delivered using biopolymers such as silk fibroins, collagen, gelatine, and others that are easily formed into suspensions. These drug carrier systems are functional at improving drug delivery and can be used in intranasal, transdermal, dental, and ocular delivery systems. This study discusses the latest developments in drug delivery methods based on nanomaterials, mainly using biopolymers like proteins and polysaccharides.

Published: March 2024

AbstractIn recent years, polymer nanospheres have been considered as one of the most common materials in the drug delivery domain. In this research, polycaprolactone‐polyethylene glycol (PCL‐PEG) blend nanospheres were produced using the electrospray method to load doxorubicin. Also, these nanospheres can be used for injection in the treatment site by poloxamer‐chitosan thermogel. In this research, PCL and PEG were used as raw materials to produce nanospheres. Then, doxorubicin was used for loading in nanospheres. The electrospray method was chosen as the method of nanosphere production. In the next step, poloxamer‐chitosan thermogel was used for injection at the treatment site. In this method, Fourier transform infrared spectroscopy, scanning electron microscopy, and rheometer techniques were used to identify the compounds and properties of the obtained specimens. Also, the MTT test was used to investigate toxicity. The results showed that PCL‐PEG polymer nanospheres were produced by loading doxorubicin using the electrospraying method with a diameter of 185 ± 23 nm. Also, these nanospheres were used for injection in the treatment site using poloxamer‐chitosan thermogel. The amount of drug release in the PLX‐CS (DOX‐PCL‐PEG)NSs was 63% in 144 h at medium pH 5.5. In the drug release system, the in‐vitro method was utilized to study the release of PLX‐CS (DOX‐PCL‐PEG) NSs. PCL‐PEG nanospheres combined in poloxamer‐chitosan thermogel polymer showed the controlled release of doxorubicin, therefore, the evaluated drug release system is considered a valuable perspective as an efficient and safe route for drug delivery in the target tissue and treating various types of cancer. This research can be used as a new method in drug delivery systems.
Delay‐independent conditions of exponential ISS for linear time‐varying delay differential systems
Authors: De Iuliis Vittorio , Manes Costanzo 
Published: March 2024

AbstractThis work focuses on linear continuous‐time systems with time‐varying delays, in the general case of time‐varying matrices. Initially, we explore the case of positive systems within this class and introduce two distinct delay‐independent conditions of exponential input‐to‐state stability. Moreover, we provide guaranteed exponential convergence rates for such conditions, explicitly stating the ISS gains. Then, we extend our analysis to systems without sign constraints, adopting a state‐bounding approach that takes advantage of the properties of positive systems. Due to the time‐varying nature of the systems, all proposed conditions are in terms of an infinite number of inequalities. Hence, implementation issues are discussed and significant special cases in which the conditions can be cast into a linear programming problem of finite dimension are presented.
Co‐channel interference cancellation based on BSS for multi‐satellite MIMO communication systems with FFR
Authors: Qin Yuan , Zhang Hang , Li Wen , Zhu Hongpeng , Li Jiong 
Published: March 2024

SummaryMultiple‐input multiple‐output (MIMO) technology can boost the capacity of conventional satellite communications, and full frequency reuse (FFR) can further improve the capacity by making full use of frequency resources. However, FFR will cause severe co‐channel interference and lead to a degradation of channel capacity. Blind source separation (BSS) algorithm can be used to eliminate co‐channel interference and does not require prior information, which avoids the extra occupation of channel frequency resources. While the multi‐satellite MIMO communication system have delay mixing characteristic, the separation performance will be degraded if the delay is ignored. In this paper, DMBSS algorithm for delay mixing is proposed. Firstly, the DMBSS algorithm utilizes Taylor expansion to achieve dimension expansion of observed signals and so as to transform the delay mixing into instantaneous mixing with extended dimension. Secondly, complex non‐orthogonal joint diagonalization algorithm is used to solve the separation matrix equation of extended observation signals and extended source signals and thus to eliminate the co‐channel interference. Simulation results show that for multi‐satellite MIMO communication scenarios with FFR, the proposed algorithm can effectively improve the performance of co‐channel interference cancellation and reduce the value of BER. Furthermore, the influence of order of Taylor expansion on the separation performance is also analyzed and simulated in this paper to show the cost performance of the proposed algorithm.
Steps to Improve the Teaching of Clinical Reasoning in Dermatology: A Scoping Review and Proposal

Published: March 2024

Abstract
Clinical reasoning (CR) is an area of active interest since faults in the diagnostic process can result in errors and possibly delays in care or even patient harm. The purpose of this scoping review was to collect information from the medical literature on approaches utilized to teach and assess CR in dermatology, identify gaps, and prepare a proposal on how to enhance the speciality’s ability to develop trainee CR skills. We conducted a review of the published literature (1990–2020) from four databases. The initial search yielded 780 papers, and 42 relevant CR publications met inclusion criteria. Demographic, thematic content, theoretical frameworks, continuum of authenticity, competency/milestone, and assessment/educational intervention data were recorded by two screeners. Trainees at different educational levels from 17 different countries have been assessed in the dermatology literature. Most publications were of a single intervention, appeared underpowered, and had small sample sizes. Only two publications examined work-based assessments (use real patients/stimuli). Knowledge-based studies were the dominant theoretical framework with no studies exclusively focused on process-based CR interventions. Simulation was well represented with 23 (55%) investigations. Rigorous studies that examine CR teaching and assessment in dermatology are lacking. Evidence-based best practices for use of work-based assessments, especially direct observation, need to be developed/adapted for dermatology and validated. Dermatology training programs would benefit from longitudinal data on trainee CR development, process-based CR educational programs, metacognition CR exploration specific to skin disease diagnosis, and studies that yield practical recommendations on how to structure multi-faceted assessments that assess CR.
The foundations of mind‐body medicine: Love, good relationships, and happiness modulate stress and promote health

Published: March 2024

AbstractAlthough stress is an everyday fact of life, it can lead to poor health outcomes, particularly when intense or prolonged. However, humans have unique cognitive abilities and thus may be able to combat stress by engaging critical psychological defence mechanisms. In this review, we discuss the field of mind‐body medicine, which focuses on improving our understanding of the mechanisms underlying this response and developing interventions that might be used to limit the effects of chronic stress. We review the findings of past and current research in this field that has focused on the impact of psychological, emotional, and behavioural factors, including love, social connectedness, and happiness on human health and the amelioration of pain as well as other signs and symptoms of disease. While these studies have not yet led to confirmed, quantifiable conclusions, the overall weight of evidence suggests that happiness (defined as a personal sense of well‐being) may be directly associated with improved health parameters and reductions in debilitating symptoms. Collectively, these findings suggest that interventions designed to promote stress mitigation, notably those that encourage social activity, may lead to significant improvements in human health.

AbstractInnovative advances in the exploitation of effective electrocatalytic materials for the reduction of nitrogen (N2) to ammonia (NH3) are highly required for the sustainable production of fertilizers and zero‐carbon emission fuel. In order to achieve zero‐carbon footprints and renewable NH3 production, electrochemical N2 reduction reaction (NRR) provides a favorable energy‐saving alternative but it requires more active, efficient, and selective catalysts. In current work, sulfur vacancy (Sv)‐rich NiCo2S4@MnO2 heterostructures are efficaciously fabricated via a facile hydrothermal approach followed by heat treatment. The urchin‐like Sv‐NiCo2S4@MnO2 heterostructures serve as cathodes, which demonstrate an optimal NH3 yield of 57.31 µg h−1 mgcat−1 and Faradaic efficiency of 20.55% at −0.2 V versus reversible hydrogen electrode (RHE) in basic electrolyte owing to the synergistic interactions between Sv‐NiCo2S4 and MnO2. Density functional theory (DFT) simulation further verifies that Co‐sites of urchin‐like Sv‐NiCo2S4@MnO2 heterostructures are beneficial to lowering the energy threshold for N2 adsorption and successive protonation. Distinctive micro/nano‐architectures exhibit high NRR electrocatalytic activities that might motivate researchers to explore and concentrate on the development of heterostructures for ambient electrocatalytic NH3 generation.
