Test rig setup for particle wear analysis in screw pumps
Authors: Moor P , Kuhr M , Pelz P 
Published: December 2024

Abstract
For many applications multi-screw pumps can be operated with minimal wear rates, thus offering long service life. Pump manufacturers are however met with increasing demand for pumps in applications with particle-laden fluids, which often lead to high wear rates. Thus, the need for design
guidelines and models for the estimation of the life expectancy arises. The scientific literature does not offer such models or published systematic studies. In this work the authors present a test rig setup for the systematic analysis of wear in operation with particle-laden fluids in multi-screw pumps. The setup is designed with repeatability of the test environment and reliability aspects in mind and draws inspiration from food and chemical processing industries.
Investigations to reduce rarefied gap flows within positive displacement vacuum pumps by utilising surface structures
Authors: Brock S , Pleskun H , Polus G , Saelzer J , Biermann D , Brümmer A 
Published: December 2024

Abstract
The ultimate pressure and efficiency of positive displacement vacuum pumps is limited by the backflow through the gaps within the machines. These gap flows are typically reduced by decreasing the gap height, which is limited for reasons of operational safety. Therefore, this study concentrates on the reduction of rarefied gap flows by means of suitable surface structures whose dimensions are small compared to the gap height without simultaneously reducing the minimum gap height. For this purpose, a method is presented to efficiently calculate the impact of the surface structure on these gap flows. Based on this method, design parameters for the choice of a suitable surface structure are discussed. Furthermore, a possible transfer for the application on the rotors is shown including a proposal for the machining process.
Sea ice perturbations in aquaplanet simulations: isolating the physical climate responses from model interventions
Authors: England M R , Feldl N , Eisenman I 
Published: December 2024

Abstract
Comprehensive climate model simulations with perturbed sea ice covers have been extensively used to assess the impact of future sea ice loss, suggesting substantial climate changes both in the high latitudes and beyond. However, previous work using an idealized energy balance model calls into question the methods that are used to perturb sea ice cover, demonstrating a consistent overestimate of the surface warming due to sea ice loss, while the large complexity gap between the idealized and comprehensive models makes the implications of this result unclear. To bridge this gap we have performed simulations with a new implementation of the CESM2 model in a slab ocean aquaplanet configuration coupled with thermodynamic sea ice, which is able to capture the realistic seasonal characteristics of polar climate change. Using this model setup, we perform a suite of experiments to systematically quantify the spurious climate responses associated with melting sea ice without a CO2 forcing. We find that using the sea ice ghost flux method overestimates many aspects of the climate response by 10%–20%, including the polar warming, the mini global warming signal and the increase in both precipitation and evaporation. The location of the latitudinal band of heating applied to melt the sea ice relative to the midlatitude jet is important for determining where the midlatitude circulation response is overestimated. This work advances our ability to isolate the true climate response to sea ice loss, and provides a framework for conducting coupled sea ice loss simulations absent the spurious impacts from the addition of artificial heating.
Understanding the opioid syndemic in North Carolina: A novel approach to modeling and identifying factors

Published: December 2024

Abstract
The opioid epidemic is a significant public health challenge in North Carolina, but limited data restrict our understanding of its complexity. Examining trends and relationships among different outcomes believed to reflect opioid misuse provides an alternative perspective to understand the opioid epidemic. We use a Bayesian dynamic spatial factor model to capture the interrelated dynamics within six different county-level outcomes, such as illicit opioid overdose deaths, emergency department visits related to drug overdose, treatment counts for opioid use disorder, patients receiving prescriptions for buprenorphine, and newly diagnosed cases of acute and chronic hepatitis C virus and human immunodeficiency virus. We design the factor model to yield meaningful interactions among predefined subsets of these outcomes, causing a departure from the conventional lower triangular structure in the loadings matrix and leading to familiar identifiability issues. To address this challenge, we propose a novel approach that involves decomposing the loadings matrix within a Markov chain Monte Carlo algorithm, allowing us to estimate the loadings and factors uniquely. As a result, we gain a better understanding of the spatio-temporal dynamics of the opioid epidemic in North Carolina.

Published: December 2024

Several studies attempt to identify predictors for weaning and extubation from mechanical ventilation (MV) and none have been shown to be particularly accurate. Therefore, the objective of the study was to evaluate whether markers of renal function may be associated with extubation failure. This retrospective study collected data through electronic medical records for 2 consecutive years. The inclusion criteria were: ≥18 years old and requiring invasive MV for a period of ≥48 hours. Extubation failure was determined when subjects needed to return to invasive MV within 48 hours of the tracheal tube withdrawal. Acute kidney injury (AKI) was assessed according to the KDIGO classification. From a total of 167 subjects, 15% evolved with extubation failure. Lower creatinine clearance and higher fluid balance was observed in the extubation failure group compared to the successful extubation group (42 mL/min vs 100 mL/min, P = 0.01 and 739 mL vs − 189 mL, P = 0.01, respectively). Subjects with AKI are 51% more likely to evolve with extubation failures than those with normal renal function (OR = 2.7; 95% CI: 1.6-4.7; P < 0.01). Renal dysfunction was related to the rate of extubation failure. Fluid balance and serum creatinine may be aspects to be considered when making the extubation decision.

Authors: Horta Ricardo , Rocha Inês S.C. , Lopes Pedro 
Published: December 2024

Background:
Over the past decade, plastic and reconstructive procedures have notably increased, driven by greater accessibility and aesthetic preferences. Despite surgeons’ efforts, patient satisfaction faces challenges due to unrealistic expectations rooted in inadequate knowledge. Preoperative consultations present an opportune moment to address this issue. This study introduces a new approach for preoperative planning: the Infinitebook. Designed to enhance patients’ understanding and satisfaction, it facilitates real-time procedure explanations and helps manage expectations.

Methods:
The Infinitebook, a versatile A5-sized notebook-like resource, aids surgeons in illustrating procedures such as abdominoplasty, liposuction, and breast reconstruction, enhancing patient understanding through real-time interaction, personalized illustrations, and sustainable practices, facilitating improved communication in plastic and reconstructive surgery. A cross-sectional study compared 2 groups: 1 using the Infinitebook-assisted explanation approach and another without. A questionnaire evaluated its impact on patients’ procedural understanding level and satisfaction with the preoperative consultation. Statistical analysis was conducted using IBM SPSS Statistics.

Results:
Participants (n = 46) were systematically sampled and categorized by demographics. Two groups (n = 23 each) received preoperative consultations with and without the Infinitebook. Perceptions on aspects of preoperative consultations were assessed. The Infinitebook received positive feedback, with all participants (100%) recommending it.

Conclusions:
This article introduces the Infinitebook, an environmentally friendly tool enhancing preoperative preparation, patient comprehension, and satisfaction in plastic and reconstructive surgery. It offers a customizable solution with potential for global implementation, with scope for further research. This study lays groundwork for future advancements in preoperative consultations and planning, promoting person-centered healthcare, and integrating new technologies.

Published: December 2024

Abstract

Objective
This study explored the association between symptoms of male menopause and presenteeism among middle-aged men in Japan.

Methods
We conducted a cross-sectional survey among 3,795 men aged 40 to 59 years who were in current employment in Japan. Male menopause symptoms were assessed using the Aging Male Symptoms (AMS) scale. Presenteeism was measured with the Work Functioning Impairment Scale (WFun). Poisson regression analysis was conducted.

Results
The prevalence of presenteeism increased with increasing total AMS scale score (p for trend <0.001). Severe AMS scale group showed prevalence ratio of 11.81 (95% confidence interval: 9.45-14.74) compared to no symptoms group. Each subscale demonstrated a dose-response relationship when evaluated independently.

Conclusions
We identified a strong association between male menopause symptoms and presenteeism. Addressing these symptoms, particularly the psychological and physical symptoms, in the workplace could reduce presenteeism.
A “Mismatched” connection: a rare case of indirect or dural carotid-cavernous fistula: a case based review
Authors: Jain Ruchit , Jagdhane Nitin , Deshmukh Sameer , Priola Stefano M. , Chavda Vishal , Chaurasia Bipin 
Published: December 2024

Introduction and importance:
A carotid-cavernous sinus fistula is an abnormal connection between the internal or external carotid artery and the venous system of the cavernous sinus. It represents a rare entity, and it is often misdiagnosed due to its overlapping symptoms with other conditions such as cavernous sinus thrombosis or orbital inflammation. Cerebral angiography continues to be the gold standard for diagnosis and surgical planning in patients with CCF, and the endovascular trans-venous approach still represents the primary line of treatment. Trans-arterial technique has become an excellent treatment option since the advent of embolic agents.

Case presentation:
Here, the authors report the case of a 42-year-old male with a one-week history of impaired visual acuity, bilateral eye edema, eye redness, and ophthalmoplegia. A neuro-ophthalmological examination found proptosis, conjunctival chemosis, and sclera injection. Examination using MR venography and digital subtraction angiography (DSA) revealed an abnormal connection between the meningeal branch of the ICA, the ECA, and the cavernous sinus. The patient received endovascular treatment with Onyx injection into the facial vein with thrombosis of the anterior cavernous sinus. The patient presented an uneventful postoperative period and was symptoms-free on postoperative day 1.

Clinical discussion:
CCF are rare and challenging conditions that require a multidisciplinary approach.

Conclusion:
The endovascular treatment represents the gold standard and usually allows an effective interruption of the abnormal vascular connection with an almost immediate resolution of the preoperative signs and symptoms.
Use of Emergency Telemedicine Physicians for Telephone Triage Disposition of Pediatric Patients
Authors: Cain Meghan R. , Iliff Benjamin W. , Russi Christopher S. , Mullan Aidan F. , Campbell Ronna L. 
Published: December 2024

Objectives:
Telemedicine is a growing field, with limited data around its utility supporting pediatric emergency care telephone triage. We instituted telemedicine physician support for nurse telephone triage decisions. When the nursing protocols recommended urgent or emergent care, a telemedicine physician reviewed and modified care urgency if appropriate. Our primary study objectives were to evaluate the proportion of patients who were downgraded to less urgent care and assess for potential harm related to the downgrade in care urgency.

Methods:
We conducted a retrospective observational cohort study of pediatric telephone calls to the Mayo Clinic Health System nurse triage line that were directed to the emergency department telemedicine physician from January 1, 2019, to December 31, 2019. Electronic medical records of patients whose care urgency was downgraded and presented to medical care within 72 hours of the triage call were reviewed.

Results:
There were 8559 nurse line calls regarding pediatric patients, 882 of which were referred to the telemedicine physician. Among these, 396/882 (44.9%, 95% confidence interval 41.6–48.3) were downgraded. Of downgraded cases, 198 (50.0%) patients sought care within 72 hours of the original call, of which 193 (97.5%) patients were discharged home from that medical visit and 5 (2.5%) patients required admission. No patients were determined to have suffered harm due to the downgrade of visit urgency.

Conclusions:
Our data suggests that telemedicine physicians can safely downgrade nurse triage care recommendations for pediatric patients. Most downgraded patients sought outpatient care, avoiding unnecessary utilization of the emergency department without evidence of associated harm.

Authors: EYVAZ Nuran , ADAR Sevda , AKÇİN Ali İzzet , DÜNDAR Ümit , TOKTAŞ Hasan , EROĞLU Selma 
Published: December 2024

ABSTRACT

Objective
Ideal volume of 5% dextrose (D5W) for median nerve hydrodissection (HD) for treating carpal tunnel syndrome (CTS) is still unknown. This study assessed the efficacy of nerve hydrodissection using varying volumes of D5W for treating mild to moderate CTS.

Design
Eighty participants with unilateral mild to moderate CTS were randomized into groups to receive either 5 ml of normal saline (NS), 5 ml of D5W, 10 ml of NS, and 10 ml of D5W, with each group undergoing one session of ultrasound-guided HD. Visual Analogue Scale (VAS), Boston Carpal Tunnel Syndrome Questionnaire (BCTQ), grip and pinch strength, cross-sectional area (CSA) of median nerve, and electrophysiological assessment were performed at baseline and weeks 4 and 12.

Results
In the 10 ml D5W group, VAS scores considerably improved compared with those in the NS groups. Although nerve CSA values decreased in all groups during follow-ups, the 10 mL D5W group showed a statistically significant improvement compared to the NS groups by the 12th week (p ≤ 0.01).

Conclusion
Ultrasound-guided median nerve HD with 10 ml D5W was more effective in reducing pain and nerve size than the NS groups at the 12th week.
Walking behavior induced by
PT
-symmetry breaking in a non-Hermitian
XY
model with clock anisotropy
Authors: Naichuk Eduard , van den Brink Jeroen , Nogueira Flavio S. 
Published: December 2024

A quantum system governed by a non-Hermitian Hamiltonian may exhibit zero-temperature phase transitions that are driven by interactions, just as its Hermitian counterpart, raising the fundamental question of how non-Hermiticity affects quantum criticality. In this context, we consider a non-Hermitian system consisting of an XY model with a complex-valued four-state clock interaction that may or may not have parity-time-reversal (PT) symmetry. When the PT symmetry is broken, and time-evolution becomes nonunitary, a scaling behavior similar to the Berezinskii-Kosterlitz-Thouless phase transition ensues, but in a highly unconventional way, as the line of fixed points is absent. From the analysis of the d-dimensional renormalization group equations, we obtain that the unconventional behavior in the PT broken regime follows from the collision of two fixed points in the d→2 limit, leading to walking behavior or pseudocriticality. For d=2+1 the near critical behavior is characterized by a correlation length exponent ν=3/8, a value smaller than the mean-field one. These results are in sharp contrast with the PT-symmetric case where only one fixed point arises for 2<d<4 and in d=1+1 three lines of fixed points occur with a continuously varying critical exponent ν.

νμ

ντ
elastic scattering in Borexino
Authors: Kelly Kevin J. , Mishra Nityasa , Rai Mudit , Strigari Louis E. 
Published: December 2024

We perform a detailed study of neutrino-electron elastic scattering using the monoenergetic Be7 neutrinos in Borexino, with an emphasis on exploring the differences between the contributions of νe, νμ, and ντ. We find that current data are capable of measuring these components such that the contributions from νμ and ντ cannot be zero, although distinguishing between them is challenging—the differences stemming from Standard Model radiative corrections are insufficient without significantly more precise measurements. In studying these components, we compare predicted neutrino-electron scattering event rates within the Standard Model (accounting for neutrino oscillations), as well as going beyond the Standard Model in two ways. We allow for nonunitary evolution to modify neutrino oscillations, and find that with a larger exposure (∼30x), Borexino may provide relevant information for constraining nonunitarity, and that JUNO may be able to accomplish this with its data collection of Be7 neutrinos. We also consider novel νμ- and ντ-electron scattering from a gauged U(1)Lμ−Lτ model, showing consistency with previous analyses of Borexino and this scenario, but also demonstrating the impact of uncertainties on Standard Model mixing parameters on these results.

FOMO driving brand nostalgia and brand personality for building trust in a food enthusiast: a serial multiple mediation model
Authors: Verma Pranay 
Published: December 2024

Purpose
During the pandemic, restaurants closed due to restrictions and economic instabilities. This research paper aims to investigate the motivational effect of nostalgia induced by fear of missing out (FOMO) upon the e-WOM about the dining place. Did FOMO evoke nostalgic memories and emotional symptoms with the dining place? It further inspected if the diners trust the restaurant for these nostalgic memories and their emotional connect.

Design/methodology/approach
A survey-based questionnaire was applied to collect data. A two-step method for analyzing the measurement and structural model was applied by using the principles of SEM to analyze the associations among key constructs in the proposed model.

Findings
Psychological constructs like nostalgia and personality drove the diners’ behavior of trust and e-WOM. The findings also confirmed the mediation effect of brand nostalgia, brand personality and brand trust between FOMO and e-WOM. Further, the model has elucidated the elaboration likelihood model (ELM) and usage gratification theories.

Originality/value
This paper has contributed to the branding literature by examining how brand constructs have mediated the path between FOMO and e-WOM. Multiple serial mediation effect among the key variables has been a novel contribution of this study. The ELM and the usage gratification theory have been integrated to extend the theoretical underpinnings in the hospitality sector.
Process quality matters: investigating the inherent characteristics of quality and performance in digital, physical and omnichannel services
Authors: Walke Fabian , Winkler Till J. 
Published: December 2024

Purpose
In the literature, quality and performance have primarily been analyzed at a micro level, particularly within individual service channels. This study aims to explore the meta-level differences between service channels in terms of quality relevance and performance in service organizations.

Design/methodology/approach
Quality relevance was measured using meta-level quality factors from the TIHPS framework and assessed by their impact on the performance of service organizations while exploring differences between digital, physical and omnichannel services through a partial least squares structural equation model.

Findings
This exploratory study reveals the high relevance of process quality on performance in physical, digital and omnichannel services. Notably, the transition from physical or digital services to an omnichannel service amplifies the importance of process quality. This finding aligns with the theoretical understanding of the relevance of process quality in service organizations. Furthermore, the study shows that quality relevance and performance vary significantly depending on the service channel.

Practical implications
Service providers should prioritize lean and efficient processes in omnichannel services. The outcome of an omnichannel service is significantly influenced by the quality of employees’ work, emphasizing the essential nature of employee training in omnichannel services. Digital services should focus on the quality of technologies, and information quality should be given particularly high priority in physical services.

Originality/value
The meta-level differences between service channels in terms of inherent quality and performance characteristics have not yet been explored in the literature. This paper addresses this research gap.
