Authors: Yumnam Gyanajeet , Devi Rajkumari Sofia , Singh Charoibam Ibohal
Published: June 2024

Purpose

The All India Institute of Medical Sciences (AIIMS) is a premier medical institution in India that has significantly contributed to cancer research. This study aims to highlight the cancer research productivity of AIIMS by assessing the impact and reach of the institution’s research output.

Design/methodology/approach

The study was based on 2,078 published papers on cancer of AIIMS indexed in the Web of Science (WoS) database from 1989 to 2021. A combination of tools such as Microsoft Excel, Biblioshiny, BibExcel and VOSviewer was used to evaluate and visualize the selected data.

Findings

The analysis revealed the interdisciplinary nature of research outputs, which have collaborative contributions from various fields such as oncology, pathology, radiology and surgery. The most productive research area within cancer was found to be breast cancer. In terms of international collaboration, the analysis revealed that AIIMS has a strong presence in the global cancer research community, with collaborations with researchers from more than 50 countries.

Research limitations/implications

This study has some limitations. First, the study is limited to using only the WoS Core Collection database. Other databases, such as Scopus and PubMed, were excluded. Second, there is ambiguity in author names and nonuniformity in the institutions’ names, which can significantly affect the study’s outcomes.

Practical implications

Identifying research productivity in cancer at AIIMS aids resource allocation, collaboration and strategic planning, enhancing India’s overall cancer research impact and patient outcomes.

Originality/value

To the best of the authors’ knowledge, this study is to use scientometric indicators to evaluate AIIMS’s research productivity with particular reference to cancer for the first time. This detailed analysis provides a deeper understanding of AIIMS’s contribution to cancer research and its potential implications.
Examining presence in immersive virtual reality and website interfaces through the cognitive fit and cognitive load theories
Authors: Martínez-Molés Víctor , Pérez-Cabañero Carmen , Cervera-Taulet Amparo
Published: June 2024

Purpose

The purpose of this paper is to assess the effects of presence on users’ information processing in mediated visualizations using immersive virtual reality (VR) and websites, focusing on information understanding and cognitive load. The impact of user interfaces on users’ perception of presence is also tested.

Design/methodology/approach

A between-subjects laboratory experiment using two user interfaces – immersive VR and website – is carried out. It is complemented by a self-administered survey on the participants.

Findings

The current results indicate that an immersive VR interface improves tourists’ information processing by producing a heightened sense of presence. The results confirm that presence facilitates tourists’ information processing by increasing information understanding and decreasing cognitive load. Finally, a negative relationship between cognitive load and information understanding is obtained.

Practical implications

VR user interfaces are not only visually appealing but also cognitively optimized. Immersive VR devices can be introduced in the specific sale process of cruise trips through both offline channels (physical stores and travel agencies) and online channels to facilitate tourists’ information processing during the prepurchase phase.

Originality/value

The primary contribution lies in the integration of the theory of presence with two influential information processing frameworks, namely, cognitive load theory and cognitive fit theory. This integration provides a holistic perspective on how user interfaces influence consumer information processing in the unique context of cruise tourism, particularly during the stage of a prepurchase information search.

Understanding Muslim consumers’ purchase intentions toward counterfeit sporting goods
Authors: Mohammadi Sardar , Ghasemi Siani Mojtaba , Dickson Geoff
Published: June 2024

Purpose

The purpose of this study was to investigate the determinants of purchase intentions for utilitarian and hedonic counterfeit sporting goods among Muslim’ consumers. The moderating effect of income and status consumption was also examined.

Design/methodology/approach

Questionnaires were distributed among male undergraduate university students who were consumers of sports goods. A total of 360 valid and usable questionnaires were collected and analyzed through descriptive and inferential statistics.

Findings

The results showed that perceived risk, personal gratification, religiosity, information susceptibility and normative susceptibility all have a positive and significant effect on negative attitudes toward counterfeit sports goods. The effect of a negative attitude toward counterfeit goods was also negative and significant for the intention to purchase utilitarian and hedonistic goods. Income was not a moderator in the relationship between negative attitudes and the intention to purchase utilitarian and hedonic goods. However, the moderating effect of status consumption on the intention to purchase both utilitarian and hedonic goods was significant.

Research limitations/implications

The use of a male-only student sample potentially limits the generalization of the findings, but not the underlying relationships between the variables. Efforts to discourage or prevent the purchase of counterfeit sporting goods should highlight the risk and reduced personal gratification associated with purchasing counterfeit products, while also appealing to a person’s faith-based ethics.

Originality/value

This study produces a novel model explaining the purchase intentions for utilitarian and hedonic counterfeit sporting goods. This model can inform the development of anti-counterfeiting strategies in Muslim countries.
Gamified immersive safety training in virtual reality: a mixed methods approach
Authors: Haj-Bolouri Amir , Katende Jesse , Rossi Matti
Published: June 2024

Purpose

The reemergence of immersive virtual technology (IVR) provides both opportunities and challenges for workplace learning (WPL). The purpose of this study is to explore and develop knowledge about how gamification influences the WPL experience by addressing two research questions: RQ1. What characterizes a gamified immersive safety training experience with IVR technology? and RQ2. How does gamified immersive safety training with IVR technology impact the WPL experience?

Design/methodology/approach

The study adopted a mixed methods approach by combining a systematic literature review with a case study on an empirical project about immersive fire safety training for train operators that are used at the Swedish train operating company SJ. The case study included data from semistructured interviews, Web survey and observation studies. The data was analyzed in two stages combining inductive and deductive data analysis for identifying themes and categories.

Findings

The findings of the study are twofold: (1) themes that conceptualize the gamified immersive safety training experience based on outputs from both the literature review and the first round of data analysis; and (2) a framework with three overarching categories that are mapped with the identified themes, and which were deduced throughout the second round of data analysis.

Originality/value

The originality of the findings stresses the implications of how a body of knowledge that synthesizes gamification concepts with immersive safety training, can inform the design of WPL experiences that are facilitated with IVR technology. As such, the implications of the findings are targeted toward both the advancement of the IVR discourse in the WPL field, but also toward practical considerations for design of immersive learning experiences that enrich WPL practices and culture.
Employee perceptions of responses to toxic leadership in the modern workplace: a Q methodological study
Authors: Bublitz-Berg Emily , Platt Carrie Anne , Hill Brent
Published: June 2024

Purpose

The purpose of this study is to explain why people respond to toxic leadership in different ways. The toxic triangle was applied as a lens and extended followership by investigating unsusceptible followers and susceptible followers.

Design/methodology/approach

This study employed Q methodology to illustrate the subjective viewpoints of 31 employees. Participants sorted 41 statements ranging from “most uncharacteristic” to “most characteristic” according to their beliefs using a forced distribution. We used qualitative data from the survey and follow-up interviews to document participant motivations.

Findings

Findings from this Q study demonstrated three distinct perceptions of responses to toxic leadership: Suffer in Silence (Perspective 1), Confront and Advocate (Perspective 2) and Quiet yet Concerned (Perspective 3). This study found that Perspectives 1 and 3 helped to explain differences in susceptible followership, whereas Perspective 2 helped to explain unsusceptible followership. Our research supports the need for organizations to provide safe whistleblowing channels for reporting unethical behavior by adopting clear policies for handling unethical behaviors and sharing those policies with all constituents within the organization.

Practical implications

Our research supports the need for organizations to provide safe whistleblowing channels for reporting unethical behavior by adopting clear policies for handling unethical behaviors and sharing those policies with all constituents within the organization.

Originality/value

Our study adds to the developing literature on followership by building a conceptual framework for response types that better explains the motivation and subsequent actions of susceptible and unsusceptible followers. This framework helps us identify new ways to combat toxic leadership by providing a more nuanced view of how employees perceive and respond to toxic leadership.
Capital structure and the firm performance nexus: the moderating and mediating roles of agency cost
Authors: Ronoowah Rishi Kapoor , Seetanah Boopen
Published: June 2024

Purpose

The purpose of this study is to examine the linear and non-linear relationship between capital structure (CS) and firm performance (FP) and the moderating and mediating roles of agency costs in the CS-FP nexus.

Design/methodology/approach

This study used static and quadratic panel data regression models to examine the linear and non-linear relationships and structured equation models to analyze the mediating effect of agency costs in the CS-FP nexus of 38 listed non-financial Mauritian firms from 2009 to 2019.

Findings

Leverage has a significant negative effect on FP supporting the pecking order theory. Agency costs are significantly and positively associated with FP. There is a strong non-linear relationship between leverage and FP supporting the trade-off and agency cost theories. Agency costs are an important moderator and mediator in the CS-FP nexus. Overall, the sensitivity analyses showed that the results were robust.

Practical implications

Firms need to carefully consider the levels and types of debt and equity in their CS involving the use of dynamic strategies to adjust CS in response to changing economic conditions and FP. The moderating effect of agency costs may guide firms in optimizing CS and may contribute to corporate governance discussions, emphasizing the importance of aligning interests to foster sustainable business practices.

Originality/value

This study adds to the extant literature by providing new evidence on the non-linear relationship between leverage and FP and the moderating and mediating roles of agency costs in the CS-FP nexus in emerging capital markets, where such studies are rare.
An analysis of capital structure heterogeneity for manufacturing and service sector firms
Authors: Shukla Ravindra Nath , Vyas Vishal , Chaturvedi Animesh
Published: June 2024

Purpose

We aim to analyze the capital structure heterogeneity for manufacturing and service sector firms. Additionally, we analyze the impact of the COVID-19 pandemic on the leverage adjustments of corporate firms.

Design/methodology/approach

This study applies the two-step system generalized method of moments (system-GMM) and panel data of 1,115 manufacturing and 482 service sector firms listed with the Bombay Stock Exchange (S&P BSE) from 2010 to 2023. We developed and analyzed three models. Model 1 analyzes the leverage determinants and speed of adjustment (SOA) for the manufacturing and service sectors. Model 2 evaluates the leverage SOA for various sub-sectors, and Model 3 analyzes the impact of the COVID-19 pandemic on the leverage SOA.

Findings

This study suggests the three following. First, the direction of leverage determinants suggests that manufacturing firms are highly tangible. In contrast, service sector firms are high-growth firms and recorded a higher SOA (12.01%) than manufacturing (9.09%). Second, analyzing the leverage heterogeneity, we found that SOA varies across the sub-sectors. For manufacturing, food and beverage sub-sector recorded the highest SOA (12.58%), while consumer durables reported the lowest (6.38%). Communication recorded the highest (24.15%) for services, while industrial services recorded the lowest (11.18%). Third, firms across sectors and sub-sectors increased their SOA during COVID-19 pandemic.

Research limitations/implications

This in-depth analysis of leverage heterogeneity for different sectors and subsectors will assist policymakers, corporate managers and other stakeholders in making agile financial decisions.

Originality/value

The analysis of leverage heterogeneity for the manufacturing and service sector from the emerging Indian economy marks a novel contribution to existing literature.
The impact of memory effect in the higher-order time-fractional derivative for hygrothermoelastic cylinder
Authors: Sheikh Shahala , Khalsa Lalsingh , Varghese Vinod
Published: June 2024

Purpose

The influence of the temperature discrepancy parameter and higher order of the time-derivative is discussed. Classical coupled and generalized hygrothermoelasticity models are recovered by considering the various special cases and illustrated graphically.

Design/methodology/approach

The theory of integral transformations has been used to study a new hygrothermal model that includes higher-order time derivatives with three-phase-lags and memory-dependent derivatives (MDD). This model considers the microscopic structure’s influence on a non-simple hygrothermoelastic infinitely long cylinder. The generalized Fourier and Fick’s law was adopted to derive the linearly coupled partial differential equations with higher-order time-differential with the two-phase lag model, including memory-dependent derivatives for the hygrothermal field. The investigation of microstructural interactions and the subsequent hygrothermal change has been undertaken as a result of the delay time and relaxation time translations.

Findings

These two-phase-lag models are also practically applicable in modeling nanoscale heat and moisture transport problems applied to almost all important devices. This work will enable future investigators to gain insight into non-simple hygrothermoelasticity with different phase delays of higher order in detail.

Originality/value

To the best of my knowledge, and after completing an intensive search of the relevant literature, the author could not learn any published research that presents a general solution for a higher-order time-fractional three-phase-lag hygrothermoelastic infinite circular cylinder with memory memory-dependent derivative.
“I’d like to carry the world sustainably” – examining sustainable consumption behavior using reusable shopping bags
Authors: Tan Caroline S.L. , Ota Satoshi
Published: June 2024

Purpose

In this study, the authors developed a conceptual model to investigate sustainable consumption behavior, specifically the intention to use reusable bags, and its relationship with two crucial factors influencing the use of single-use plastic bags: cost savings and convenience. This study also aims to explore the mediating roles of environmental concern, guilt and self-efficacy.

Design/methodology/approach

A quantitative study using online survey involving 421 respondents was conducted, and data analysis performed using structural equation modeling.

Findings

The results indicate that self-efficacy influenced environmental concern and sustainable consumption, while perceived savings did not. Perceived convenience significantly influenced sustainable consumption behavior. Environmental concern had indirect effects on the relationships between perceived savings, perceived convenience and sustainable consumption behavior, whereas guilt did not moderate the relationship between environmental concern and sustainable consumption behavior.

Originality/value

The main contribution lies in the insights for promoting the sustainable use of reusable shopping bags, benefiting both theoretical understanding and practical applications in efforts to encourage sustainable consumption behavior.
The effect of organizational learning on business sustainability – the role of distributed leadership
Authors: Zgrzywa-Ziemak Anna Helena , Walecka-Jankowska Katarzyna Anna , Zimmer Joanna
Published: June 2024

Purpose

The paper aims to investigate the importance of leadership – distributed leadership (DL) – for the relationship between organizational learning (OL) and business sustainability (BS).

Design/methodology/approach

Extensive literature research was carried out to investigate the relationship among leadership, OL and BS. Two theoretical frameworks of the relationship among DL, OL and BS were formulated and tested on the basis of the empirical studies conducted in 694 Polish and Danish companies. The moderated multiple regression and mediation analysis were used.

Findings

In-depth, critical literature analysis has shown that the theoretical foundation of the relationship between leadership and BS is limited and not empirically verified. However, the empirical study has revealed a positive, statistically significant effect of DL on both OL and BS and the mediating role of OL on the relationship between DL and BS (a partial and complimentary mediation).

Research limitations/implications

It would be valuable to simultaneously consider other leadership types (beyond DL) in terms of their impact on OL and BS. Additionally, due to the nature of BS challenges and the specificity of DL, other factors influencing BS should be included for a more profound understanding of the relationships under investigation. Finally, additional contextual factors need to be taken into account.

Originality/value

To the best of the authors’ knowledge, the paper is one of the first studies that present the relationship between OL and BS with reference to factors influencing BS, i.e. leadership. The value of the paper is the development of two alternative models of the relationship among DL, OL and BS and their verification through large-scale empirical cross-country research. Furthermore, the results obtained in the course of the research open up new research directions with respect to the development of the concept of sustainable leadership and deepen the knowledge of the relationship between leadership types and OL.
A review on improving the sensitivity and color stability of naturally sourced pH‐sensitive indicator films
Authors: Guo Chang , Li Ying , Zhang Hao , Zhang Quanyu , Wu Xiaodan , Wang Ying , Sun Fangda , Shi Shuo , Xia Xiufang
Published: June 2024

Naturally sourced pH‐sensitive indicator films are of interest for real‐time monitoring of food freshness through color changes because of their safety. Therefore, natural pigments for indicator films are required. However, pigment stability is affected by environmental factors, which can in turn affect the sensitivity and color stability of the pH‐sensitive indicator film. First, natural pigments (anthocyanin, betalain, curcumin, alizarin, and shikonin) commonly used in pH‐sensitive indicator films are presented. Subsequently, the mechanisms behind the change in pigment color under different pH environments and their applications in monitoring food freshness are also described. Third, influence factors, such as the sources, types, and pH sensitivity of pigments, as well as environmental parameters (light, temperature, humidity, and oxygen) of sensitivity and color stability, are analyzed. Finally, methods for improving the pH‐sensitive indicator film are explored, encapsulation of natural pigments, incorporation of a hydrophobic film‐forming matrix or function material, and protective layer have been shown to enhance the color stability of indicator films, the addition of copigments or mental ions, blending of different natural pigments, and the utilization of electrospinning have been proved to increase the color sensitivity of indicator films. This review could provide theoretical support for the development of naturally sourced pH‐sensitive indicator films with high stability and sensitivity and facilitate the development in the field of monitoring food freshness.
State efforts to enforce firearm dispossession through relinquishment laws
Authors: Oliphant Stephen N. , Zeoli April M.
Published: June 2024

Research Summary

Although federal law prohibits firearm possession by individuals who have been convicted of a disqualifying offense and those who are subject to certain domestic violence protective orders (DVPOs), it does not provide a mechanism for enforcing firearm dispossession. Some states have adopted relinquishment laws to enforce firearm possession restrictions among prohibited persons following a disqualifying status or conviction. To date, limited research has assessed the statutory characteristics of firearm relinquishment laws related to DVPOs. We build on this work by assessing DVPO and conviction‐based relinquishment statutes, including legislative changes through time, to identify gaps in policy.

Policy Implications

Our analysis revealed that many states still lack statutory elements that are expected to increase the likelihood of firearm dispossession, such as requiring the court to order relinquishment, strict standards for providing proof of firearm transfer or some form of compliance verification, and provisions that authorize law enforcement to recover unrelinquished firearms. The absence of such elements may facilitate unlawful firearm retention by those who become prohibited possessors. States might consider adopting relinquishment provisions that outline clear requirements for actors (i.e., judges, prohibited possessors, law enforcement) at each stage of the process to ensure that firearms are relinquished following a disqualifying conviction or DVPO.
Performance measure skewness and the structure of CEO compensation: Theory and evidence
Authors: Chaigneau Pierre , Chang Woo‐Jin , Hillegeist Stephen A.
Published: June 2024

While research has analyzed how the structure of incentive pay relates to the dispersion of the performance measure distribution, as measured by its variance or volatility, we examine how it relates to the asymmetry of the distribution, as measured by its skewness. In contrast to the variance, skewness affects the relative informativeness of high and low performance about the agent's effort, which determines the relative efficiency of providing rewards and punishments for incentive purposes. Therefore, skewness is an important determinant of compensation convexity, which is determined by the relative holdings of stock and options. Consistent with our analytical and numerical results, we find that the skewness of expected earnings is negatively associated with the convexity of CEO compensation. Our results are economically significant, robust to alternative specifications, and do not appear to be driven by reverse causality. In addition, we find that earnings skewness is negatively associated with total CEO compensation and that this association is driven by lower options‐based compensation. These findings are consistent with CEOs preferring positively skewed performance metrics. Overall, we provide theoretical, numerical, and empirical evidence suggesting that skewness is a more important determinant of the convexity and structure of CEO compensation than volatility.
Ireland: Political Developments and Data in 2023
Authors: ARLOW JONATHAN , O'MALLEY EOIN
Published: June 2024

Ireland had, for a long time, been an outlier in European politics in that, despite having experienced large‐scale immigration in the 2000s, it had not seen a significant expression of anti‐immigrant sentiment, and it was almost absent at a political level. The year 2023 saw a significant rise in the number of people seeking international protection or asylum. The state struggled to cope with the rise in numbers, which saw it take control of hotels and other private premises across the country. Protests grew in some localities, but the political reaction was negligible until in late November, there was a riot in Dublin city centre causing millions of euros worth of damage. There was an expected impact on Irish politics that might change the shape of politics in Ireland.

Employment, education or training status (NEET) at baseline predicts high‐threshold symptomatic remission in first episode psychosis: A cohort study
Authors: Buckle Jessica , Kavanagh Gail , Connolly Aries , Arora Sophie , Forshall Emily , Murphy Titus , Pereira Marco , Whale Richard
Published: June 2024

Aim

Clinical studies following a first episode of psychosis (FEP) have increasingly exposed the complexity of identifying predictive outcome variables. We aimed to explore the utility of NEET status (not in education, employment or training) at FEP onset in predicting high threshold clinical remission (absence of positive symptoms and off antipsychotic medication for 6 months) at 3 years following treatment with an early intervention for psychosis service.

Methods

We studied an established retrospective naturalistic cohort of 354 patients with FEP (the S1P cohort).

Results

Baseline NEET status was identified in 172 patients (49%) and was significantly associated with mean duration of untreated psychosis (p = .035). Only 64 (21%) achieved defined remission criteria by 3 years. Multivariate logistic regression analysis revealed baseline NEET status as the only variable significantly associated with remission status (p < .001).

Conclusion

NEET may represent an important predictive variable of symptomatic outcomes which requires prospective evaluation.
Letermovir as secondary prophylaxis of cytomegalovirus infection after allogeneic hematopoietic cell transplantation: A single center experience
Authors: Desai Nihar , Pasic Ivan , Law Arjun D. , Lam Wilson , Gerbitz Armin , Viswabandya Auro , Kim Dennis D. , Kumar Rajat , Mattsson Jonas , Novitzky‐Basso Igor , Michelis Fotios V.
Published: June 2024

Letermovir, a novel anti‐cytomegalovirus (CMV) agent acts by inhibiting the viral terminase complex and is approved for primary prophylaxis in CMV seropositive patients post allogeneic hematopoietic cell transplantation (HCT). The favorable efficacy and safety profile make it an attractive option for use as secondary prophylaxis in patients at high‐risk for CMV reactivation. In this study, we report the efficacy and safety of letermovir secondary prophylaxis after at least one treated episode of CMV reactivation in a cohort of 39 high‐risk patients. Thirty two (82%) patients received anti‐thymocyte globulin (ATG), 27 (69%) received a combination of ATG and post‐transplant cyclophosphamide for graft‐versus‐host disease (GVHD) prophylaxis. Twenty one patients (54%) received CMV seronegative grafts. In addition, 18 (46%) patients had HLA mismatched unrelated or haploidentical donors while 18 (46%) had active GVHD requiring immunosuppression at the time of commencing secondary prophylaxis. Letermovir was initiated at a median of 47 days (range, 41–56) after HCT and was administered for a median duration of 77 days (range, 46–90). A single breakthrough CMV reactivation was noted in this high‐risk cohort. Four additional episodes of CMV reactivation occurred at a median of 28 days (range, 23–59 days) after discontinuation of secondary prophylaxis. The drug was well tolerated and 77% of the cohort completed the planned duration of secondary prophylaxis. None of the patients discontinued treatment due to treatment‐related adverse effects. In conclusion, letermovir is effective and well tolerated and may be considered for secondary prophylaxis in patients at high risk for CMV reactivation. Prospective studies are required to validate these findings.
ERTRÄUMTE RÄUME DER FREIHEIT: LUISE MÜHLBACHS PROTAGONISTINNEN ZWISCHEN REALITÄT UND WUNSCHVORSTELLUNG
Authors: Popławska Magdalena
Published: June 2024

On the basis of selected works by the ‘Vormärz’ writer Luise Mühlbach, this article examines the extent to which the writer's assertions relate to the image she portrays of her protagonists. This question seems all the more interesting because Mühlbach was socially and politically engaged, practised social criticism and pleaded for a change in the situation of women. The upheavals in the social and political spheres of the nineteenth century enabled Mühlbach to include aspects of women's emancipation in her writing. The focus of this article is on her portrayal of female protagonists. In addition, it questions whether Mühlbach's women accept their role in life, or whether they are able to protest against male domination and thus to secure their freedom.
Accuracy and clinical role of digital templating for total knee arthroplasty performed on haemophilic knees
Authors: Vahabi Arman , Er Erdem , Biçer Elcil Kaya , Şahin Fahri , Kavakli Kaan , Aydoğdu Semih
Published: June 2024

Introduction

In total knee arthroplasty (TKA), choosing the correct implant size is important. There is lack of data on accuracy of templating on haemophilic knees. Our aim was to test the accuracy of 2D digital templating for TKA on haemophilic arthropathy (HA) of knee.

Materials and Methods

TKAs performed on HA between January 2011 and January 2022 were screened. Osteoarthritis (OA) group was created as control group by a one‐to‐one matching regarding type of implant used. Intra‐ and interobserver correlations were measured in HA, then correlation between templated and implanted sizes was investigated in four assessments (femur AP, femur lateral, tibia AP, tibia lateral), then compared with OA group. Fifty‐eight knees in each group included.

Results

Regarding intraobserver correlation in HA, there was excellent correlation for femur AP [.93 (.73–.98)], femur lateral [.98 (.91–.99)], and tibia AP (1.0) templating. Regarding interobserver correlation in HA, excellent correlation was observed for femur lateral [.93 (.74–.98)] and tibia AP templating [.90 (.65–.97)]. Regarding correlation of templated and applied sizes in HA; tibia AP, tibia lateral and femur lateral templating showed good correlation [.81 (.70–.89), .86 (.77–.91), .79 (.67–.87) while femur AP templating showed moderate correlation [.67 (.50–.79)]. Comparing HA and OA, there was no difference in correlation levels regarding femur AP, femur lateral, tibia AP and tibia lateral templating (p = .056, p = .781, p = .761, p = .083, respectively).

Conclusion

Although 2D digital templating shows comparable correlation in HA and OA, clinical applicability of templating on HA appears to be limited in its current state.
Nursing care of TURP and hyperglycemia integrating symptoms management model
Authors: Subrata Sumarno Adi , Masithoh Robiul Fitri , Şahin Büşra , Kuhnke Janet L. , Aldiabat Khaldoun M.
Published: June 2024

Transurethral resection of the prostate (TURP) is a surgical procedure often used to treat benign prostatic hyperplasia. TURP often results in multiple symptoms that worsen a patient's condition, such as hyperglycemia. The relationship between TURP and hyperglycemia is not direct, but it is important to consider the potential impact of hyperglycemia on individuals undergoing TURP. The most critical point in the TURP syndrome is early diagnosis and treatment. Nurses should be aware of the symptoms to prevent further outcomes. To optimise the nursing care, integrating of symptoms management model in TURP care is important as it provides a conceptual foundation for understanding patient care, guides clinical decision‐making, contributes to evidence‐based practice and fosters professional development. Also nurses can deliver high‐quality TURP and hyperglycemia care that meets the diverse needs of patients and contributes to positive health outcomes. However, a study describing the symptoms management of patients living with TURP syndrome and hyperglycemia is limited. Therefore, the article aims to explain the management of hyperglycemia among patients after TURP. The findings of this review are expected to help the nurses notice the symptoms and make accurate interventions along with evaluations.
Later (“evening”) circadian preference is associated with poorer executive, academic, and attentional functioning in adolescents with and without ADHD
Authors: Becker Stephen P. , Brown Aleah , Langberg Joshua M. , Beebe Dean W.
Published: June 2024

Background

Adolescents vary considerably in their circadian phase preference; those with greater “eveningness” (also known as “night owls”) have later bedtimes, wake times, and peak arousal compared to those with greater “morningness.” Prior research suggests that (a) greater eveningness is associated with worse academic, executive, and attentional functioning; and (b) adolescents with attention‐deficit/hyperactivity disorder (ADHD) tend to be high in eveningness and to have deficits in these school‐related constructs. However, few studies have examined circadian preference alongside two potential confounds—sleep duration and sleep quality—as predictors of daytime functioning, or whether the strength of associations differs across adolescents with and without ADHD.

Methods

Participants were 302 adolescents (Mage = 13.17 years; 44.7% female; 81.8% White); approximately half (52%) had ADHD. A multi‐method, multi‐informant design was used. Specifically, adolescents reported on their circadian preference, school night sleep duration, and sleep quality. Adolescents provided ratings of their academic motivation (intrinsic, extrinsic, and amotivation) and were administered standardized achievement tests in reading and math. Adolescents and parents completed ratings of daily life executive functioning (behavioral, emotion, and cognitive regulation), and they and teachers also provided ratings of ADHD inattentive symptoms.

Results

Above and beyond sleep duration, sleep quality, and covariates (sex, family income, pubertal development, medication use), greater eveningness was uniquely associated with poorer academic, executive, and attentional functioning across most measures. Sleep quality was uniquely associated with a handful of outcomes, and sleep duration was not significantly uniquely associated with any outcome in the regression analyses. ADHD status did not moderate effects.

Conclusions

This study provides compelling evidence that poorer academic, executive, and attentional functioning are more closely associated with greater eveningness than with sleep duration or quality in adolescents. Findings suggest that targeting circadian preference may be important to reduce these problems in adolescents, especially in clinical samples such as ADHD for whom academic, executive, and attentional difficulties are exceptionally common.
Impact of hormone replacement therapy on all‐cause and cancer‐specific mortality in colorectal cancer: A systematic review and dose‒response meta‐analysis of observational studies
Authors: Liu Kefeng , He Yazhou , Li Qiong , Sun Shusen , Mei Zubing , Zhao Jie
Published: June 2024

Objective

The effect of hormone replacement therapy (HRT) on colorectal cancer (CRC) mortality and all‐cause mortality remains unclear. We conducted a systematic review and dose–response meta‐analysis to determine the effects of HRT on CRC mortality and all‐cause mortality.

Methods

We searched the electronic databases of PubMed, Embase, and The Cochrane Library for all relevant studies published until January 2024 to investigate the effects of HRT exposure on survival rates for patients with CRC. Two reviewers independently extracted individual study data and evaluated the risk of bias between the studies using the Newcastle‒Ottawa Scale. We performed a two‐stage random‐effects dose–response meta‐analysis to examine a possible nonlinear relationship between the year of HRT use and CRC mortality.

Results

Ten cohort studies with 480,628 individuals were included. HRT was inversely associated with the risk of CRC mortality (hazard ratios (HR) = 0.77, 95% CI (0.68, 0.87), I2 = 69.5%, p < 0.05). The pooled results of seven cohort studies revealed a significant association between HRT and the risk of all‐cause mortality (HR = 0.71, 95% CI (0.54, 0.92), I2 = 89.6%, p < 0.05). A linear dose–response analysis (p for nonlinearity = 0.34) showed a 3% decrease in the risk of CRC for each additional year of HRT use; this decrease was significant (HR = 0.97, 95% CI (0.94, 0.99), p < 0.05). An additional linear (p for nonlinearity = 0.88) dose–response analysis showed a nonsignificant decrease in the risk of all‐cause mortality for each additional year of HRT use.

Conclusions

This study suggests that the use of HRT is inversely associated with all‐cause and colorectal cancer mortality, thus causing a significant decrease in mortality rates over time. More studies are warranted to confirm this association.

Objective

As a large and populous country, China releases a high number of diagnostic criteria. However, the published diagnostic criteria have not yet been systematically analyzed. Therefore, the aim of this study is to investigate the characteristics, development methods, reporting quality, and evidence basis of diagnostic criteria published in China.

Methods

We searched five databases for diagnostic criteria from their inception until July 31, 2023. All diagnostic criteria were screened through abstract and full‐text reading, and included if satisfying the prespecified criteria. Two researchers independently extracted data on the characteristics, development methods, reporting quality, and evidence basis of diagnostic criteria.

Results

A total of 143 diagnostic criteria were included. In terms of development methods, the proportions of diagnostic criteria that involved a systematic literature search (n = 2; 1.4%; 95% confidence interval (CI), 0.4% to 5.0%), adoption of formal consensus methods (n = 4; 2.8%; 95% CI, 1.1% to 7.0%), and criteria validation (n = 9; 6.3%; 95% CI, 3.3% to 11.5%) were relatively low. Regarding reporting quality, the average compliance with the ACCORD checklist was 5.1%; none of the diagnostic criteria reported on registration, expert inclusion criteria, expert recruitment process, or consensus results. A majority (58.7%; 95% CI, 50.6% to 66.5%) of criteria did not cite any research, and only one (0.7%; 95% CI, 0.1% to 3.9%) criterion was derived from a systematic review. Moreover, only 16.1% (95% CI, 11.0% to 23.0%) of diagnostic criteria used evidence from the Chinese population.

Conclusion

The diagnostic criteria developed in China exhibit serious flaws, particularly in evidence retrieval, formation of expert panels, consensus methods, and validation. Additionally, only few diagnostic criteria used a systematic synthesis of the evidence or evidence from the China. There is an urgent need to enhance the methodology for developing diagnostic criteria.
Potential kidney protective effects of glucagon‐like peptide‐1 receptor agonists

Published: June 2024

Glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) have gained increasing attention for their potential benefits in people with type 2 diabetes (T2DM) with chronic kidney disease (CKD). This class of medication has demonstrated promising results in reducing albuminuria, preserving estimated glomerular filtration rate (eGFR), and mitigating cardiovascular (CV) risk, making them potential therapeutic options for individuals with CKD. The kidney protective effects of GLP‐1RAs extend beyond glycaemic control, and are thought to be attributed to their anti‐inflammatory, antioxidant, and natriuretic properties. Despite these promising findings, the use of GLP‐RAs has yet to be definitively shown to slow progression to chronic kidney failure, or reduce CV and kidney related death in people with T2DM and CKD. The Research Study to See How Semaglutide (a once weekly subcutaneous administered GLP‐1RA) Works Compared to Placebo in People with Type 2 Diabetes and Chronic Kidney Disease (FLOW trial) was recently stopped because of efficacy. The primary end point for the FLOW trial consists of a composite endpoint of (i) onset of chronic kidney failure; (ii) death from kidney failure; (iii) cardiovascular death; and (iv) onset of a persistent ≥50% reduction in eGFR from baseline. It has also been reported by the sponsors of the trial that the primary end point of the trial was reduced by 24% with both CKD and CV outcomes contributing to risk reduction. In anticipation of the results of the FLOW trial being published, we review the current evidence surrounding kidney outcomes and proposed kidney protective pathways associated with GLP‐1RA use.
Evaluation of the SpotChecks contrast sensitivity test in healthy adults

Purpose

SpotChecks is a new contrast sensitivity (CS) test designed for self‐monitoring of vision. This study assessed the test–retest repeatability of take‐home SpotChecks, in‐office SpotChecks and near Pelli–Robson charts in healthy adults.

Methods

One eye of 61 healthy adults with near visual acuity (VA) of 6/9 or better (age range 22–84, mean 49 [18] years) was tested during two office visits (mean 10 [8] days apart). Each visit included high‐contrast VA, then 12 randomly ordered CS tests (6 different SpotChecks and 6 different Pelli–Robson) under the same lighting (luminance 110 cd/m2), all at near in the same eye with habitual correction. The same eye was self‐tested with take‐home SpotChecks once a day on 6 days between the office visits. SpotChecks was scored by the logCS at the highest line with ≥2 errors. Pelli–Robson was scored by [0.05 × number of letters read correctly − 0.15]. Repeatability of logCS was defined as 1.96 Sw, Sw representing within‐subject standard deviation. Comparison for repeatability was performed with Bootstrap hypothesis test.

Results

SpotChecks and Pelli–Robson showed similar intra‐session or inter‐visit repeatability (p = 0.14–0.81). Inter‐day repeatability for take‐home SpotChecks was 0.18 logCS, the same as that from the first measurements of two office visits with SpotChecks or Pelli–Robson. Inter‐visit repeatability improved to 0.15 by using the average of two repeated measurements for SpotChecks (p = 0.02) or three repeated measurements for Pelli–Robson (p = 0.04). Age showed a small effect on logCS (−0.015/decade, p = 0.02) for both SpotChecks and Pelli–Robson. Mean logCS was 0.05 lower in those ≥50 years (SpotChecks 1.84 [0.10] and Pelli–Robson 1.77 [0.10]) compared with those <50 years of age (SpotChecks 1.89 [0.07] and Pelli–Robson 1.83 [0.07]).

Conclusions

SpotChecks showed good repeatability with take‐home and in‐office testing in healthy adults, making it a promising tool for monitoring disease progression at home.
You've got to hide your myopia away: John Lennon's contact lenses
Authors: Vincent Roslyn A. , Vincent Stephen J.
Published: June 2024

John Lennon has an enduring, instantly recognisable, iconic, spectacle look. However, prior to 1966, he was rarely seen wearing glasses in public. From ages 7 to 26, he effectively hid his myopia away, including a period of unsuccessful contact lens wear during Beatlemania. This narrative review examines John's experience with contact lenses from 1963 to 1966 when he wore corneal rigid lenses made from polymethylmethacrylate, which regularly fell out. This frequent lens ejection was most likely due to the interaction between his upper eyelid and a spherical back surface rigid lens fitted to his right eye, which had a moderate degree of with‐the‐rule corneal astigmatism. John's recollection that his contact lenses stayed in place while ‘stoned’ supports this hypothesis, as a cannabis‐induced upper eyelid ptosis would reduce the likelihood of lens ejection.
