AimsRobotic arm-assisted surgery offers accurate and reproducible guidance in component positioning and assessment of soft-tissue tensioning during knee arthroplasty, but the feasibility and early outcomes when using this technology for revision surgery remain unknown. The objective of this study was to compare the outcomes of robotic arm-assisted revision of unicompartmental knee arthroplasty (UKA) to total knee arthroplasty (TKA) versus primary robotic arm-assisted TKA at short-term follow-up.MethodsThis prospective study included 16 patients undergoing robotic arm-assisted revision of UKA to TKA versus 35 matched patients receiving robotic arm-assisted primary TKA. In all study patients, the following data were recorded: operating time, polyethylene liner size, change in haemoglobin concentration (g/dl), length of inpatient stay, postoperative complications, and hip-knee-ankle (HKA) alignment. All procedures were performed using the principles of functional alignment. At most recent follow-up, range of motion (ROM), Forgotten Joint Score (FJS), and Oxford Knee Score (OKS) were collected. Mean follow-up time was 21 months (6 to 36).ResultsThere were no differences between the two treatment groups with regard to mean change in haemoglobin concentration (p = 0.477), length of stay (LOS, p = 0.172), mean polyethylene thickness (p = 0.065), or postoperative complication rates (p = 0.295). At the most recent follow-up, the primary robotic arm-assisted TKA group had a statistically significantly improved OKS compared with the revision UKA to TKA group (44.6 (SD 2.7) vs 42.3 (SD 2.5); p = 0.004) but there was no difference in the overall ROM (p = 0.056) or FJS between the two treatment groups (86.1 (SD 9.6) vs 84.1 (4.9); p = 0.439).ConclusionRobotic arm-assisted revision of UKA to TKA was associated with comparable intraoperative blood loss, early postoperative rehabilitation, functional outcomes, and complications to primary robotic TKA at short-term follow-up. Robotic arm-assisted surgery offers a safe and reproducible technique for revising failed UKA to TKA.Cite this article: Bone Joint J 2024;106-B(7):680–687.

AimsThe primary aim of this study was to assess the feasibility of recruiting and retaining patients to a patient-blinded randomized controlled trial comparing corticosteroid injection (CSI) to autologous protein solution (APS) injection for the treatment of subacromial shoulder pain in a community care setting. The study focused on recruitment rates and retention of participants throughout, and collected data on the interventions’ safety and efficacy.MethodsParticipants were recruited from two community musculoskeletal treatment centres in the UK. Patients were eligible if aged 18 years or older, and had a clinical diagnosis of subacromial impingement syndrome which the treating clinician thought was suitable for treatment with a subacromial injection. Consenting patients were randomly allocated 1:1 to a patient-blinded subacromial injection of CSI (standard care) or APS. The primary outcome measures of this study relate to rates of recruitment, retention, and compliance with intervention and follow-up to determine feasibility. Secondary outcome measures relate to the safety and efficacy of the interventions.ResultsA total of 53 patients were deemed eligible, and 50 patients (94%) recruited between April 2022 and October 2022. Overall, 49 patients (98%) complied with treatment. Outcome data were collected in 100% of participants at three months and 94% at six months. There were no significant adverse events. Both groups demonstrated improvement in patient-reported outcome measures over the six-month period.ConclusionOur study shows that it is feasible to recruit to a patient-blinded randomized controlled trial comparing APS and CSI for subacromial pain in terms of clinical outcomes and health-resource use in the UK. Safety and efficacy data are presented.Cite this article: Bone Jt Open 2024;5(7):534–542.

The landscape of ultrafast structured light pulses has significantly advanced thanks to the ability of high-order harmonic generation (HHG) to translate the spatial properties of infrared laser beams to the extreme-ultraviolet (EUV) spectral range. In particular, the up-conversion of orbital angular momentum (OAM) has enabled the generation of high-order harmonics whose OAM scales linearly with the harmonic order and the topological charge of the driving field. Having a well-defined OAM, each harmonic is emitted as an EUV femtosecond vortex pulse. However, the order-dependent OAM across the harmonic comb precludes the synthesis of attosecond vortex pulses. Here we demonstrate a method for generating attosecond vortex pulse trains, i.e., a succession of attosecond pulses with a helical wavefront, resulting from the coherent superposition of a comb of EUV high-order harmonics with the same OAM. By driving HHG with a polarization tilt-angle fork grating, two spatially separated circularly polarized high-order harmonic beams with order-independent OAM are created. Our work opens the route towards attosecond-resolved light-matter interactions with two extra degrees of freedom, spin and OAM, which are particularly interesting for probing chiral systems and magnetic materials.
Endorsement of HIV-related stigma among men in Ghana: What are the determinants?
Authors: Saaka Sulemana Ansumah , Antabe Roger 
Published: July 2024

Introduction
Stigma and discrimination against people living with HIV (PLHIV) remain a major barrier to effective HIV prevention. Despite the understanding that the creation of a socially inclusive environment for PLHIV is crucial for the promotion of testing, status disclosure, and treatment uptake, HIV stigma persists. Additionally, evidence suggests the endorsement of HIV stigma may be gender specific. Nonetheless, very little is known about the factors influencing men’s discrimination against PLHIV in the Ghanaian context. Guided by the theory of planned behavior, our study fills this void by exploring the factors associated with the endorsement of HIV stigma in Ghana.

Methods
Utilizing a nationally representative data from the 2022 Ghana Demographic and Health Survey (DHS) (N = 7044 men with ages ranging from 15–49 years), and applying logistic regression models, this study examined the factors associated with the endorsement of HIV-related stigma in Ghana.

Results
The notion that HIV can be transmitted through the sharing of food with PLHIV was significantly associated with increased odds of stigma endorsement against children with HIV (OR = 3.381; P<0.001) and vendors with HIV (OR = 3.00; P<0.001). On the contrary, knowing that a healthy-looking person can have HIV was significantly associated with decreased odds of endorsement of stigma against children living with HIV (OR = 0.505; P<0.001), and vendors living with HIV (OR = 0.573; P<0.001). Likewise, having knowledge of drugs that help PLHIV to live longer, was significantly associated with decreased odds of stigma endorsement against children living with HIV (OR = 0.768; P<0.001), and vendors living with HIV (OR = 0.719; P<0.001). Moreover, participants with higher educational attainment reported lower odds of stigma endorsement against children living with HIV (OR = 0.255; P<0.01), and vendors living with HIV (OR = 0.327; P<0.01). Furthermore, age was significant and inversely associated with the endorsement of HIV stigma against children living with HIV (OR = 0.951; P<0.05), and vendors living with HIV (OR = 0.961; P<0.05). Also, wealth, ethnicity, and the region of residence significantly predicted endorsement of HIV stigma.

Conclusion
For Ghana to achieve UNAIDS target 95-95-95 by 2030, targeted educational campaigns are necessary to dispel misconceptions about HIV and to promote social inclusion for reducing HIV-related stigma and discrimination in the country.

Introduction
Compelling evidence shows that the COVID-19 pandemic has detrimental effects on the mental health of university students. However, little is known about the psychological distress experienced by students from high schools during the pandemic. This study, therefore, sought to examine the prevalence of depression, anxiety and stress and their associated factors among students from high schools in Rwanda.

Methods and materials
A retrospective, cross-sectional study was conducted on 384 students randomly selected from high schools. Data were collected using standardized measures of mental disorders and their associated factors. Bivariate and multivariate analyses based on the odds ratio were used to indicate the associated factors of anxiety, depression, and stress.

Results
The results indicated that slightly above half of the participants (51%, n = 195) had clinically significant symptoms of depression, 30.3% (n = 116) had stress and 67.3% (n = 259) had anxiety. Our analyses identified several key risk factors associated with increased odds of these mental disorders. These include exposure to domestic violence, COVID-19 symptoms like cough and myalgia, eating twice per day, having one of the three mental disorders, gender, with females showing higher susceptibility, and direct contact with the people who positively tested covid-19. Conversely, protective factors such as heightened awareness about Covid-19, positive mental health, social support, eating three times, belonging to the third Ubudehe category, and a high resilience emerged as significant elements mitigating the risks of these mental health challenges within our sample. Intriguingly, religious affiliation emerged as a notable factor, with students affiliated with the Witness of Jehovah and Adventist denominations exhibited lower risks for depression and anxiety.

Conclusion
Our findings highlighted a high prevalence of depression, anxiety, and stress among students from secondary schools. Interestingly, this study also revealed the associated risk and protective factors of depression, anxiety, and stress in Rwandan students in high schools. Therefore, mental health interventions targeting the impact of COVID-19 on students, as young people are needed.

Authors: Peggie Djunijanti , Supadi Supadi 
Published: July 2024

Idea blanchardii is one of many endemic butterfly species in Sulawesi, Indonesia. This species is among the highly traded butterfly species thus requires biological information on the captive breeding. The aim of this study was to obtain data on the adult life-span, to report the multivoltine generation, and to provide conservation-related insight. Captive breeding research on this species was conducted within the period of September 2018 until February 2020. The host plant, Parsonsia alboflavescens, was used to support the life of this species for ovipositing and larval food plant. The adults would visit almost any flowers available at the facility. In total, 696 individuals were observed. Data on mating information of the species is presented here. Observations on when a female lays eggs are also revealed. This research showed that I. blanchardii is polygamous and polyandrous. Individuals of this species could live much longer than other butterfly species. A few could live over 80 days and one still seen laying eggs at the age of 136 days old.
No Country for God: The Brutality of Western Territorial Appropriation in Blood Meridian
Authors: García Jiménez Sergio 
Published: July 2024

Abstract
In 1985 American author Cormac McCarthy published Blood Meridian, a novel that is set against the backdrop of the conquest of the West, a momentous and still relevant process that has acquired quasi-mythical dimensions throughout history and that is undoubtedly embedded in the United States’ national consciousness. In this article I will show the different mechanisms employed by Cormac McCarthy to deconstruct conventional Western narratives that glorify and sanction the Westward expansion as a courageous endeavour that shaped the American nation, hence underplaying the more devastating and pernicious side of this chapter of America’s imperialistic undertakings. To that end, I will argue that McCarthy contests the main tenets of the crucial 1893 Frontier Thesis proposed by Frederick Jackson Turner, in particular the depiction of American colonial expansion as a source of progress and democratic development; likewise I will contend that, in Blood Meridian, McCarthy aligns himself with the ideas of New Western Historians that offer a revisionist perspective of the country’s past, revealing such brutality and wickedness exerted in the appropriation of the western territories that seemed to deprive the process of any hope of God’s mercy.

Published: July 2024

Abstract
Increasing environmental awareness and concerns about global warming have resulted in a significant demand for sustainable and eco-friendly resources, such as naturally available fibers, that can be suitable alternatives to petroleum/synthetic materials such as glass, carbon and Kevlar in reinforced composites. The exploration of natural fibers as reinforcements in composites is increasing in popularity, particularly in the development of transport and household components. However, natural fibers also have a few limitations that should be addressed appropriately, including lack of compatibility between fiber-matrix, fiber swelling, excess absorption of moisture, resistance to chemicals and fire. Consequently, various processes have been used to improve the fiber surface, to obtain a better fiber–matrix interface. The primary objective of this work is to review the impact that a 5 % NaOH (sodium hydroxide) treatment has on the chemical, mechanical, and thermal properties of natural fiber-reinforced composites (NFRC).

Published: July 2024

Abstract
In this paper, we define and study the variety of tense modal pseudocomplemented De Morgan algebras. This variety is a proper subvariety of the variety of tense tetravalent modal algebras. A tense modal pseudocomplemented De Morgan algebra is a modal pseudocomplemented De Morgan algebra endowed with two tense operators G and H satisfying additional conditions. Also, the variety of tense modal pseudocomplemented De Morgan algebras is intimately connected with some well-known varieties of De Morgan algebras with tense operators.
Less is sometimes more – some examples of the reduction of hazardous substances in metallographic etching
Authors: Schnarr H. 
Published: July 2024

Abstract
In metallography, the choice of the right etchant is crucial for visualizing the microstructure. As conventional etching agents generally contain a more or less high proportion of hazardous substances that need to be reduced in the future, examples are given of how this reduction is possible in principle. This reduction in hazardous substances is mainly achieved through microscopy contrasts, dilution of etching solutions and electrolytic etching.

Published: July 2024

In many parts of the world, degradation of grazing lands is one of the most important environmental issues. This study analyzed farmers’ perception of area closure and its associated factors of participation in degraded grazing land restoration in Sede-Muja Woreda, Northwest Ethiopia. A cross-sectional research design and a mixed research approach were applied in this study. The 384 sample respondents were randomly selected. Household surveys, interviews, focus groups, and field study techniques were used to acquire the data. A binary logistic regression model was used to identify the determinant elements that affect farmers' participation in the area closure of degraded grazing land restoration. All of the total respondent farmers (100%) have a positive attitude towards multi-functionality benefits of area closures for local farmers. The model results show that the grazing experience (AOR = 2.981,95% CI = (1.143-7.775), access to safety net program (AOR = 2.787,95% CI = (1.146-6.77), access to livestock forage (AOR = 4.493,95% CI = (1.149-14.028), access to extension service (AOR = 2.522,95% CI = (1.917-6.6397), livestock ownership (AOR = 0.026,95% CI = (0.008-0.087), improved cattle breeds (AOR = 4.955,95% CI = (1.944-12.630), access to training (AOR = 3.169,95% CI = (1.409-7.131), farmers’ perception (AOR = 0.085,95%CL = (0.023-0.310), and communities’ consensus (AOR = 4.230, 95% CI = (1.377-12.996) were determinant factors that affect farmers' participation in the area closure of degraded grazing land restoration. To address the current grazing land degradation issues, every one of the relevant authorities as well as communities needs to work together to create modern grazing land management mechanisms such as grazing land enclosures, reduce animal size through improved cattle breeds, implement zero-grazing systems, and ensure the sustainability of existing enclosures.
Land use/land cover (LULC) changes modeling and susceptibility mapping using the binary logistic regression at the territorial level in eastern DR Congo

Published: July 2024

The Land Use and Land Cover (LULC) changes are commonly used to determine the landscape conditions and have significant impacts on the earth's surface processes. During the last three decades, there has been an acceleration of LULC changes in Eastern DR Congo. However, there is no comprehensive overview of the drivers of these changes at the territorial level in this region, even though the knowledge of these drivers is important for land use planning and spatial modeling of environmental changes. Using the Kalehe Territory as a case study, this work sought to fill this gap by analyzing the drivers of LULC changes during the 1987-2020 period. A mixed approach combining remote sensing, Geographic Information System, and logistic regression modeling was used. The results indicated that the prominent LULC changes in the study area are deforestation, built-up area expansion, cropland expansion, and shrubland expansion. These changes are significantly influenced by biophysical factors (slope, altitude, and soil type), conservation zoning, population dynamics, and accessibility factors at different levels. The occurrence of conservation zones decreases the susceptibility to deforestation, built-up land, and cropland expansions. In contrast, the proximity factors (distance to road, artisanal mining, and locality) increase the susceptibility to LULC changes. These factors can be integrated into spatial models to forecast LULC changes susceptibility in this region. Furthermore, the establishment of future land use management policy at the territorial level in eastern DR Congo should be space-specific as the susceptibility of LULC changes shows a spatial trend.

The aim of the study was to evaluate the antimicrobial effect of single and repeated nitric oxide (NO) exposure on the major pathogens of nosocomial pneumonia isolated from the sputum of cardiac surgery patients.Materials and Methods. A 24-hour culture of microorganisms from pan-resistant isolates of Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, and Klebsiella pneumoniae from the sputum of inpatient cardiac surgery patients with nosocomial pneumonia, as well as strains of P. aeruginosa and E. coli from the American Type Culture Collection (ATCC), were exposed to 200 ppm NO (experimental sample) or medical air (control sample) in a sealed chamber for 30 minutes. After a single or 4 repeated gas exposure at 4 h intervals, Petri dishes were placed in a thermostat at 37°C and the results were evaluated at 24 and 48 h or at 12, 24, 36 and 48 h, respectively. Grown colonies were counted using an automated colony counter and recorded as CFU/mL.Results. No growth of clinical isolates of P. aeruginosa and E. coli was observed 24 and 48 h after a single exposure to NO. Growth of A. baumannii was lower compared to controls at 24 h but continued at 48 h. No effect of a single exposure to 200 ppm NO on other microorganisms was observed. After 4 exposures to NO, the growth of ATCC E. coli was not detected, the growth of other experimental strains was significantly lower compared to the control (P<0.05).Conclusion. Our results provide a rationale for the use of multiple intermittent inhalation of 220 ppm NO for the treatment of patients with hospital-acquired bacterial pneumonia.

Authors: Fasa Azmi 
Published: July 2024

Numerous educational institutions in Indonesia suffer financial deficits, negatively impacting educational quality. This study aims to ascertain the Tuition Fees at Nurul Fajri Islamic Boarding School Majalengka utilizing the Activity-Based Costing (ABC) method. It investigates the application of the ABC method in determining Tuition Fees within educational foundation institutions, a novel approach, particularly for pesantren foundations. The research adopts a qualitative methodology with a problem-focused approach. Data collection involved interviews and an analysis of pertinent financial and operational documents. Cost activity data was processed using ABC costing, resulting in tuition fees calculations based on the ABC method. These calculations were then juxtaposed with the Tuition Fees established by the school administration. The analysis identified a cost discrepancy (undercharging), where the cost per student exceeded the total Tuition Fees income and School Operational Funds (SOF) or Government Subsidy. For junior high school grades 1, 2, and 3, the differences were Rp 68,092, Rp 65,877, and Rp 85,668, respectively. For high school levels 1, 2, and 3, the discrepancies were Rp 6,674, Rp 49,014, and Rp 51,354, respectively. The study recommends that the school increase the monthly tuition fees to adequately cover the actual costs of education.
