Ein guter Zeitpunkt für Vereinfachungen
Authors: Schaub Michael , Floß Alexander
Published: November 2024

„Regeln sind kein Selbstzweck, weshalb es nicht mehr Regeln geben soll, als erforderlich.“ Insgesamt 18 Mal enthielt der Koalitionsvertrag zwischen CDU, CSU und FDP aus dem Jahr 2009 diese und ähnliche Bekenntnisse zum Bürokratieabbau. Zum gleichen Zeitpunkt wurden dem Normenausschuss Heiz- und Raumlufttechnik sowie deren Sicherheit (NHRS) des DIN insgesamt 237 Normen zugeordnet. Der Koalitionsvertrag von 2021 zwischen SPD, Bündnis 90/Die Grünen und FDP führt die Notwendigkeit des Bürokratieabbaus sogar 26 Mal auf. Im NHRS ist die Anzahl der Richtlinien unserer Branche derweil auf rund 300 angestiegen. Ist das der richtige Weg? Ein Plädoyer für weniger Regulierungen.

Authors: Claus Philipp
Published: November 2024

Die stetige Zunahme von Starkregenereignissen unterstreicht die Bedeutung und Notwendigkeit von Notentwässerungen auf Flachdächern. Größere Regenspenden bewirken erhöhte statische Belastungen auf die Flachdachkonstruktionen, zudem muss das Niederschlagswasser separat auf eine schadlos überflutbare Fläche auf dem Grundstück abgeleitet werden können. Der Fachbeitrag erklärt die Anforderung nach DIN 1986–100 und gibt nützliche Hinweise zur Entwässerung von Dachflächen.
The Relevance of Demographic Similarity and Factuality in Social Influencer Communication Culture – A Comparison Between Hedonic and Utilitarian Conditions
Authors: von Mettenheim Walter , Wiedmann Klaus-Peter
Published: November 2024

This work identifies differences in the success factors of influencers given consumers’ consumption goals (hedonic vs. utilitarian). Although practitioners have complained about the lack of know-how regarding this issue, research on the topic remains scarce. Hypotheses on the differing relevance of the demographic similarity of influencers and consumers and of the factuality of influencers’ communication are verified through an empirical investigation. The scenario is consumers’ selection of a hotel for (1) a holiday (hedonic consumption goal) or (2) a professional/university seminar (utilitarian consumption goal). The results are analyzed by structural equation modeling and multigroup analysis. We generate some surprising results. Counterintuitively, demographic similarity is more important under utilitarian than hedonic conditions. Factuality seems equally important in both conditions. Explanations and implications of these findings are provided.
Asymmetric Uncertainty Around Earnings Announcements: Evidence from Options Markets
Authors: Saurava Sumit , Agarwalla Sobhesh Kumar , Varma Jayanth R.
Published: November 2024

We use the Indian stock options market to study the evolution of uncertainty and asymmetric uncertainty around earnings announcements (EAs). We find that uncertainty (implied volatility) and asymmetric uncertainty (options skew) increase monotonically before the EA day and decrease after EA. Options volume (relative to spot and to futures) also exhibits similar behavior, suggesting that informed investors prefer options markets to spot and futures markets. Both options skew and put-to-call volume ratio can predict the sign of the EA surprise one day before EA, indicating that price discovery and information assimilation happen in the options market.
Shifting Under Pressure: Timing Practices within Regulatory Information Disclosure Programs
Authors: Desai Vinit
Published: November 2024

Research examines the process through which regulatory agencies and other powerful third parties publicly disseminate information about organizations in order to reduce the information asymmetry between those organizations and their dispersed or less powerful stakeholders. These disclosure programs are presumed to work by mobilizing stakeholders to pressure organizations for change. Prior studies focus on organizations’ resistance to that external pressure, often drawing from theories of institutional forces and organizational legitimacy. Instead, the present study examines the public disclosure process itself, and adapts research on organizational learning and collective attention focus to develop new theory regarding how organizations may selectively time their practices to influence these disclosures in their favor. Results suggest that organizations may respond to disclosure programs and other governance structures when actively monitored, but may drift out of compliance during intervening periods. Findings also suggest that strong governance outside of the regulatory disclosure process can help to reduce these problems. The study contributes to corporate governance, organizational learning, and other literatures by developing new theory regarding the timing of organizational responses to regulatory interventions, and by providing evidence that overlapping forms of oversight may mitigate the limitations within any one particular governance mechanism.
A Model of Insolvency Resolution: When is Bankruptcy Inefficient?
Authors: Acha Rajesh Kumar , Sarkar Sumit , Guha Apratim , Ayyalusamy Kanagaraj
Published: November 2024

Information asymmetry about a firm's value has been identified in the literature as an obstacle in restructuring the debt of an insolvent firm. We explore the possibility of a restructuring under complete and symmetric information between a firm and its creditors in a creditor-friendly bankruptcy regime. Using a model, we determine the feasibility conditions for restructuring. Our results show that restructuring the firm's debts may not be possible even if it is known to the creditors that the firm's value under the present management is higher than that under a bankruptcy sale. The firm's value under restructuring must also be large enough to pay the full claim of the unsecured creditor and pay the secured creditor a little more than the claim payment they receive in a bankruptcy sale. The results highlight the role of creditors' legal rights in a creditor-friendly regime in leading a firm towards a bankruptcy sale even when the creditors know that the firm's value is more under the present management.
A Yin-Yang Perspective of Street-Level Policy Entrepreneurs
Authors: Ren Monica , Xing Hua , Xing Puyao
Published: November 2024

We introduce a cultural perspective, Yin-Yang logic, to explore how street-level policy entrepreneurs (SLPEs) formulate policy and foster inter-local collaborations across 14 Chinese cities. Drawing on a case forming the Chinese Eastern Northeast Economic Zone (2003-2016), we identify 20 critical incidents through interviews and content analysis. We make four main theoretical contributions: (i) this study is the first in the SLPEs literature to introduce a cultural perspective, the Yin-Yang logic, for understanding the complex yet central role that SLPEs play in policy innovation; (ii) it reveals a sequential six-stage process view in policy innovation formation from the Yin-Yang perspective; (iii) it extends our understanding of policy actors, SLPEs, as change agents outside Western democracies and provides the Yin-Yang perspective for dealing with the contextual paradoxical conditions; and (iv) SLPEs demonstrate three Yin-Yang framed capabilities in harnessing the natural momentum (shi) generated by the interaction and balancing forces of Yin-Yang dynamics.
How and When Leaders’ Self-Sacrifice Backfires: Examining the Impact on Subordinate Unethical Pro-Organizational Behavior
Authors: Mishra Madhurima , Ghosh Koustab , Sharma Dheeraj , Anand Smriti
Published: November 2024

Self-sacrificial leadership has generally been studied in terms of its beneficial effects on organizations. However, recent research has challenged this notion by highlighting that leaders’ self-sacrifice can also produce dysfunctional outcomes for leaders and their followers. The present study draws on social identity theory and extends this novel perspective by examining whether self-sacrificial leader behaviors can inadvertently encourage unethical pro-organizational behavior (UPOB) among subordinates. The study further explores the mediating role of organizational identification and the moderating role of followers’ unethical tolerance and ethical organizational climate. Using time-lagged data from 271 employees, results confirm that leaders’ self-sacrifice is indirectly related to UPOB through organizational identification. The indirect relationship gets weakened when followers have low unethical tolerance, and the organizational climate is highly ethical. This study augments our understanding of the antecedents of UPOB and the boundary conditions under which UPOB may be curtailed. Implications for theory and practice are discussed.
The Ethics of Unhealthy Food and Beverage Advertising to Children: A Bibliometric Analysis and Future Research Agenda
Authors: Gupta Parul , Srivastava Ritu , Jain Shalini , Jain Shailendra P.
Published: November 2024

The widely advertised category of unhealthy food and beverages (F&B) is calorie-dense, nutrient-poor, and associated with long-term harm, particularly for children. Business literature has been largely silent regarding the ethicality of its advertising targeting children and lacks clarity on questions future research needs to address. Based on a bibliometric analysis of 1,851 articles published between 1973 and 2021 containing 70,379 citations, we uncovered five intellectual clusters underlying research on the ethics of unhealthy F&B advertising to children (ATC). Importantly, we propose a concrete roadmap featuring actionable and pertinent unanswered questions to stimulate research in this crucial domain.

Published: November 2024

Customer satisfaction is crucial for the sustained success of e-commerce platforms, necessitating effective Customer Relationship Management (CRM) strategies to bolster relationships and overall performance. While existing research provides insights into factors like payment methods, shipping times, and customer demographics that influence satisfaction, significant gaps remain in fully understanding these dynamics, particularly within specific contexts such as Olist, a prominent Brazilian online marketplace. This study aims to address these gaps by leveraging advanced machine learning techniques on a comprehensive dataset comprising 100,000 orders spanning 2016 to 2018. Through meticulous analysis, which includes rigorous feature selection and the application of predictive models like logistic regression, decision trees, and random forests, we pinpoint crucial determinants of customer satisfaction. Our findings underscore the pivotal role of operational efficiencies in shaping customer experiences and offer actionable recommendations for enhancing e-commerce performance. By bridging these research gaps, this study not only contributes to the existing body of knowledge but also informs practical strategies for optimizing customer satisfaction and guides future research endeavors in the realm of e-commerce and CRM.

Commentary on "Preliminary Species Hypotheses" in Entomological Taxonomy: A Global Data and FAIR Infrastructure Perspective
Authors: Islam Sharif
Published: November 2024

What if early taxonomic findings were treated like preprints, open to iterative improvement, or managed with practices from the open-source community, such as Git branching, merging, and patch management? Prompted by Buckley's article Charting a Future for Entomological Taxonomy in New Zealand (2024), this commentary explores these possibilities in the context of biodiversity informatics. In response to the need for rapid, scalable biodiversity monitoring, Buckley introduces preliminary species hypotheses (PSH) as a bridge between quick identification tools and the rigorous Linnaean system, leveraging DNA barcoding and AI-assisted image recognition to produce provisional classifications that can later be validated. Expanding on Buckley’s framework, this commentary emphasises the critical role of data linking, versioning, and integration to support evolving taxonomic data. Borrowing from software and open-source practices, I explore the idea of managing PSH with an infrastructure that treats each taxonomic update as a versioned "commit," which can be tracked, refined, and integrated over time. Drawing insights from FAIR (Findable, Accessible, Interoperable, Reusable) principles and Digital Extended Specimens, I identify infrastructure requirements for PSH, including robust data standards, persistent identifiers, and interoperability to support global biodiversity repositories. Additionally, Taxonomic Digital Objects offer a model for dynamically integrating PSH into adaptable taxonomies that can evolve with new data and tools. By positioning PSH within an open, infrastructure-focused framework, this commentary advocates for scalable, hypothesis-driven biodiversity data that meets modern conservation needs, bridging traditional and emerging practices in taxonomy.
Atomic and electronic properties of 2D Chevrel phases: A case study of the superatomic two-dimensional semiconductor Re6Se8Cl2
Authors: Chibisov Andrey N. , Smotrova Daria M. , Chibisova Mary A. , Fedorov Aleksandr S.
Published: November 2024

The design of two-dimensional superatomic materials, which form their atomic structures through covalently bonded clusters with variable chemical compositions, will enable the development of new materials with promised electronic properties that are beneficial for modern nanoelectronics. This paper presents ab initio calculations of the atomic and electronic structures of both bulk and 2D Re6Se8Cl2. The calculations were carried out using density functional theory, incorporating noncollinear spin density and the pseudopotential method. The results include data on the atomic structure, band gap value, formation energy of the Re6Se8Cl2 2D layer, and the redistribution of atomic charges within the structures. The differences in effective masses for electrons and holes in the two-dimensional and bulk Re6Se8Cl2 materials are demonstrated, along with an explanation of how these differences impact their transport properties. The findings are expected to be of great significance for the design, synthesis, and implementation of new two-dimensional superatomic materials with controlled properties in modern nanoelectronics.

Clarifying the phylogenetic placement of Eupoinae Maddison, 2015 (Araneae, Salticidae) with ultra-conserved element data
Authors: Zhang Junxia , Ni Yi , Marathe Kiran , Wang Yaozhuo , Maddison Wayne P.
Published: November 2024

The subfamily Eupoinae Maddison, 2015 is an enigmatic group of minute leaf-litter-dwelling jumping spiders from Southeast Asia. Although previous molecular phylogenetic studies have suggested that it is one of the basal (non-salticine) lineages within jumping spiders, its exact placement remains unclear. In this study, ultra-conserved element data were collected from major salticid lineages to investigate the phylogenetic relationships of all salticid subfamilies, with a special focus on the placement of Eupoinae. The results provide a well-supported phylogeny for jumping spider subfamilies, and suggest a sister relationship of Eupoinae with Spartaeinae Wanless, 1984, a basal lineage of jumping spiders with relatively high species diversity and morphological and behavioural diversity. With the placement of Eupoinae, we have resolved the relationships of all salticid subfamilies, supplying a robust framework for evolutionary studies of jumping spiders.
Clinical Comparison of a Small-Aperture Intraocular Lens Versus a Monofocal Control
Authors: Vukich John , Modi Satish , Fisher Bret L. , Stonecipher Karl , Lin Ling , Michna Magda
Published: November 2024

Purpose

To evaluate range of visual acuity, visual quality, and safety of the IC-8 small-aperture (SA) intraocular lens (IOL) (Apthera; Bausch & Lomb, Inc) in patients with cataract.

Methods

This was a prospective, multicenter, open-label, parallel-group, non-randomized, examiner-masked, 12-month clinical study conducted at 21 sites in the United States. Included patients (N = 453) received either the SA IOL (targeted to −0.75 diopters) in one eye and a monofocal or monofocal toric IOL (targeted to plano) in the fellow eye (SA IOL group, n = 343) or bilateral monofocal/monofocal toric IOLs (control group, n = 110).

Results

At 6 months, the SA IOL group achieved superior binocular uncorrected intermediate and near visual acuity (
P
< .0001) and equivalent binocular uncorrected distance visual acuity versus the control group. In SA IOL eyes, 99.1% achieved monocular corrected distance visual acuity of 0.3 logarithm of the minimum angle of resolution or better. The SA IOL and control groups had comparable binocular photopic and mesopic contrast sensitivities at 6 months both with and without glare. The SA IOL group reported few visual symptoms overall, although at higher rates than in the control group.

Conclusions

The SA IOL group exhibited improved intermediate and near vision, comparable distance vision and binocular contrast sensitivities, and few visual symptoms or adverse events versus the bilateral monofocal/monofocal toric IOL group, suggesting that the SA IOL is an effective option for presbyopia correction at the time of cataract surgery.

Changes in Corneal Higher Order Aberrations Following Cataract Surgery With Different Incision Sites: A Prospective, Randomized Study
Authors: Akbas Yusuf Berk , Gul Cengiz , Guler Muzaffer Said , Yildirim Yusuf
Published: November 2024

Purpose

To compare the effect of superior and temporal clear corneal incisions, regardless of the steep axis, on postoperative changes in corneal higher order aberrations (HOAs) in patients with healthy corneas and mild preoperative corneal astigmatism.

Methods

In this prospective cohort study, the right eyes of study participants were randomly assigned to one of two groups prior to cataract surgery: temporal incision (TI) and superior incision (SI). Preoperatively and 6 weeks after surgery, measurements were taken of corneal HOAs over a 6-mm optical zone.

Results

The study included 102 eyes (50 eyes in the TI group and 52 eyes in the SI group) that underwent routine phacoemulsification using a 2.4-mm clear corneal incision. Significant changes in vertical coma (
P
= .019), horizontal coma (
P
= .042), and vertical trefoil (
P
= .001) were observed in the SI group. In the subgroup analysis of the SI group, significant changes in vertical coma (
P
= .025) and vertical trefoil (
P
= .047) were observed in the eyes with preoperative with-the-rule corneal astigmatism, and significant changes in horizontal coma (
P
= .038) were observed in eyes with preoperative against-the-rule corneal astigmatism. The TI group showed no significant difference between the preoperative and postoperative periods.

Conclusions

The SI induced vertical and horizontal coma in accordance with the preoperative axis of the steep meridian. These alterations in corneal HOAs may affect the quality of vision after surgery. TI may potentially provide an advantage over SI in terms of corneal HOAs.

Ray-tracing–Guided or Q-Value–Adjusted FS-LASIK for Correction of Myopia and Myopic Astigmatism: A Comparative Contralateral Eye Study
Authors: Yuan Yifei , Zhang Ruiyu , Wang Zizhen , Wang Yuexin , Zhang Yu , Chen Yueguo
Published: November 2024

Purpose

To compare the safety and efficacy of individualized ray-tracing–guided femtosecond laser–assisted in situ keratomileusis (FS-LASIK) for correction of myopia and myopic astigmatism.

Methods

This prospective, randomized, double-blind, contralateral eye study included 68 eyes of 34 patients with myopia or myopic astigmatism requiring FS-LASIK treatment. For each patient, one eye was randomly assigned to receive the ray-tracing–guided treatment, whereas the contralateral eye underwent Q-value–adjusted ablation. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent (MRSE), sphere, cylinder, effective optical zone (EOZ), and 6-mm corneal aberrations were measured and analyzed before operation and after a 3-month postoperative follow-up.

Results

At 3 months postoperatively, the UDVA of 20/16 or better was measured in 94% of eyes in the ray-tracing group and 85% of eyes in the Custom-Q group (
P
= .064). Forty-seven percent in the ray-tracing group and 32% in the Custom-Q group gained one or more Snellen lines of CDVA (
P
= .043). The MRSE, refractive astigmatism, surgically induced astigmatism, and difference vector were better in the Custom-Q group (
P
< .05). The postoperative corneal HOAs and optical path difference were significantly better in the ray-tracing group (
P
= .008). The EOZs of the ray-tracing and Custom-Q groups were 5.77 and 5.43 mm (
P
< .001), and the average ablation depths of the ray-tracing and Custom-Q groups were 100.97 and 85.24 µm (
P
< .001), respectively.

Conclusions

Despite the overcorrection and excessive ablation of corneal tissue, ray-tracing–guided FS-LASIK in clinical practice was found to be safe and effective for myopic correction both with and without astigmatism, particularly in achieving UDVA and inducing fewer corneal HOAs and less OPD.

Reasons for Re-treatment Following Monovision Laser Refractive Surgery
Authors: Safir Margarita , Kastin Roni , Kaiserman Igor , Sela Tzahi , Munzer Gur , Mimouni Michael
Published: November 2024

Purpose

To assess the incidence and causes for re-treatment following monovision laser refractive surgery in a large data study spanning a decade.

Methods

The setting for this retrospective comparative study was Care Vision Laser Center, Tel Aviv, Israel. This study included patients aged 36 to 60 years who underwent monovision laser vision correction at the Care Vision Laser Centers, Israel, from January 2012 to December 2022. Demographic, preoperative, and postoperative data were retrieved for analysis.

Results

Overall, 3,674 eyes of 1,847 patients were included. Re-treatment was performed in 1.28% (n = 47) of eyes, 0.84% (n = 31) distance-targeted and 0.44% (n = 16) near-targeted. Monovision reversal in near-targeted eyes occurred due to overcorrection (37.5%, n = 6 of 16), despite being on target (25%, n = 4 of 16), insufficient myopia (18.8%, n = 3 of 16), and de novo astigmatism (12.5%, n = 2 of 16). One eye was targeted for near vision due to de novo astigmatism. Re-treatment in distance-targeted eyes was due to myopic undercorrection (45.2%, n = 14 of 31), myopic regression (19.4%, n = 6 of 31), myopic overcorrection (12.9%, n = 4 of 31), hyperopic regression (6.5%, n = 2 of 31), astigmatism undercorrection (6.5%, n = 2 of 31), de novo astigmatism (6.5%, n = 2 of 31), and astigmatism regression (3.2%, n = 1 of 31). Re-treatment was more likely in distance targeted eyes of patients with monovision compared to near-targeted eyes (
P
= .025) and patients without monovision (
P

Conclusions

In monovision laser vision correction, retreatment in the near-targeted eye is rare when the ideal near target (−1.50 to −1.25 diopters) is achieved. However, the distance-targeted eye is more likely to require re-treatment. Surgeons can plan monovision surgery and advise patients accordingly.

“None of us wanted that”: Gerald Boland’s Irish Civil War, 1922-1924
Authors: Kelly Stephen
Published: November 2024

Gerald Boland, a militant revolutionary, politician and statesman, has until now ranked amongst the relatively neglected figures of the Irish Revolution, including the Irish Civil War (1922-1923) and the nascent years of the Irish Free State. This article addresses this anomaly. Based on a chronological framework covering the outbreak of the Irish Civil War in June 1922 to Boland’s release from prison in the summer of 1924, it provides a unique insight into his hitherto overlooked Civil War experiences. It argues that despite his participation in key events Boland detested the Civil War. Boland’s Civil War experiences confirmed his preference for pragmatism over idealism from a military standpoint, and at the same time revealed a nascent politician (albeit vastly inexperienced) driven by a sense of realism. As such, the essential elements of Boland’s republicanism comprised pragmatic realism rather than doctrinaire idealism.
Margaret Buckley’s The Jangle of the Keys, A Call to Continued Action
Authors: Dubois Claire
Published: November 2024

Margaret Buckley (1879-1962) was a key figure in the struggle for Ireland’s independence, trade unionism and the rights of women. After she rejected the Treaty and became an active member of the Women’s Prisoners’ Defence League, she was arrested in January 1923 and interned until October 1923. Her prison experiences provided the material for The Jangle of the Keys (1938) – a testimony on the trauma of imprisonment for republican women as the Free State and the Church were waging a war against them. It recounts the physical and psychological brutality the women faced and the way they constructed their own society inside the prisons to try and maintain their agency, while challenging the authority of the prison administration and the power of the Free State. Buckley offers a subversive narrative of the Civil War, and goes against the official silence against women, enabling a passage from invisibility to a form of visibility and conforming to Jacques Rancière’s theory of the “dissensus”.

Background: Although total intravenous anesthesia (TIVA) with propofol and remifentanil is frequently used to optimize intraoperative neurophysiological monitoring (IONM), the exact effect of remimazolam on IONM remains unknown. Here, we compared the effects of propofol and remimazolam along with remifentanil on IONM during TIVA.Methods: In this prospective, double-blind, randomized controlled trial, 64 patients requiring IONM during cervical spine surgery were administered either propofol (Group P) or remimazolam (Group R). The preoperative latencies of the somatosensory-evoked potentials (SEP; N20 for the median nerve and P37 for the tibial nerve) were measured. SEP latencies and amplitudes and motor-evoked potential (MEP) amplitudes were measured 30 min after anesthetic induction (T1), 30 min after surgical incision (T2), after laminectomy or discectomy (T3), immediately after plate insertion or pedicle screw fixation (T4), and before surgical wound closure (T5). The primary outcome was the between-group difference in the N20 latency changes measured at T1 and preoperatively.Results: The change in SEP latencies including N20 and P37 at T1 compared with preoperative time was not significantly different between Groups P and R. Except for the amplitude of the right abductor brevis, there was no significant group-by-time interaction effect for intraoperative MEP amplitudes or SEP latencies and amplitudes. Conclusions: TIVA with remimazolam and remifentanil for cervical spine surgery yielded stable IONM, comparable to those observed with conventional TIVA with propofol and remifentanil. Further clinical trials are needed in other surgical contexts and with more diverse patient populations to determine the effects of remimazolam on IONM.
Prevalence of depressive symptoms in adolescents living with HIV in Johannesburg, South Africa

Published: November 2024

Background: Adolescents living with HIV (ALWHIV) are more vulnerable to developing depressive symptoms. Despite this knowledge, the screening for depression is not routinely integrated into HIV treatment programmes.Aim: The study aimed to determine the prevalence of depressive symptoms among ALWHIV.Setting: The study was carried out in the primary healthcare clinics and an antiretroviral clinic situated in a district hospital, West Rand District, Johannesburg.Methods: This was a cross-sectional study of 125 ALWHIV. The modified Patient Health Questionnaire for Adolescents (PHQ-A) was used to screen for depressive symptoms with a score of ≥ 5 deemed significant. A distress protocol was used for immediate psychological intervention.Results: The prevalence of depressive symptoms was 44.8% and the majority of ALWHIV reported mild-moderate symptoms (36.8%). Overall, 25.6% of adolescents had suicidal behaviours. Those with psychosocial difficulties and those who reported a previous suicide attempt were 3.6 (adjusted odds ratio [aOR] 3.59, 95% confidence interval [CI]:1.17–11.03) and 6.9 (aOR 6.93, 95% CI:1.39–34.55) times likely to develop depressive symptoms, respectively.Conclusion: A high prevalence of depressive symptoms was found in ALWHIV. Psychosocial difficulties and previous suicide attempts were predictive factors for depressive symptoms. This highlights the unmet need for the integration of mental health screening and overall mental health services into adolescent HIV programmes.Contribution: This study emphasises an urgent need for routine mental health screening and prompt psychosocial support in ALWHIV.

The investigation of factors associated with susceptibility to severe malaria is best achieved using case-control studies. The presence of a history of severe malaria in controls could affect the quality of their phenotype and study findings and hence should be rigorously determined. Here, we assessed the performance of a qualitative questionnaire to identify a history of cerebral malaria in controls in a case-control study of severe malaria in Mali. We evaluated the archived medical records of 220 children diagnosed with severe diseases at health care centers in rural and urban settings in Mali from 2018 to 2019. Parents of enrolled children were then identified and interviewed using a structured questionnaire by an investigator blinded to the diagnosis. The diagnosis derived from the interview was then compared with the diagnosis from the medical records as the reference diagnosis. The sensitivity and specificity of the questionnaire to detect cerebral malaria in history were, respectively, 84% and 76%. The questionnaire was concordant with the medical record diagnosis in 60% (95% CI: 50–71%) of cases. For other clinical phenotypes of malaria (severe malaria anemia, uncomplicated malaria, and severe malaria anemia concurrent with cerebral malaria), sensitivity and specificity ranged from 42% to 85% and 88% to 96%, respectively. Positive and negative predictive values were, respectively, 75% and 85%. The questionnaire demonstrated suitable sensitivity and specificity to identify cerebral malaria in a participant’s history. In sub-Saharan Africa, a region with suboptimal medical record archives, such a tool could be used in case-control studies of severe malaria to select controls.
Minor Hosts Have a Major Impact on the Enzootic Transmission of Borrelia burgdorferi

In the northeast United States, subadult deer ticks feeding on white-footed mice are thought to drive the force of transmission of Borrelia burgdorferi (B. burgdorferi), the agent of Lyme disease. However, control measures targeting mice have produced inconsistent results, suggesting that other animals are significant contributors to enzootic transmission. Such contributions have previously been difficult to quantify. We used a retrotransposon-based host blood meal assay to measure the relative contribution of hosts to enzootic B. burgdorferi transmission at two insular sites in Massachusetts. Over 6 years, we identified mice and deer as the most common larval hosts at our Nantucket Island site. Infected nymphal ticks were derived mainly from mice (35%) and shrews (31%), despite shrews having fed only 12% of larvae. Deer were identified in 19% of the infected nymphs, despite their known reservoir incompetence. Shrews were consistently the most important host in our Martha’s Vineyard site and were identified as the source of 41% of nymphs overall and 39% of the infected nymphs. Sciurids were variable contributors, feeding from 4% to 42% of the larval ticks each year, and contributed no infected nymphs in 2020 and as many as 83% in 2023. We conclude that host contributions to feeding larval ticks change over time and within sites and that shrews may be more influential than mice at some sites. Shrews, sciurids, and even deer may contribute to B. burgdorferi maintenance. Hosts that apparently feed a minor proportion of ticks can have a major impact on the force of B. burgdorferi transmission.
