A Simulation Study for a Safe Reopening and Operation of the Trager Institute Optimal Aging Clinic During the COVID-19 Pandemic
Authors: Sadri Shahab , Paleshi Arsalan , Bai Lihui , Gentili Monica 
Published: August 2023

In this study, we develop a discrete-event simulation model to aid the Trager Institute, an outpatient clinic for optimal aging located in Louisville, Kentucky, in determining their safe reopening strategies during the COVID-19 pandemic and operational strategies beyond the pandemic. The model studies the movement of several groups of people (e.g., healthcare providers, navigators, patients, staff) and the operations of the clinic’s primary and ancillary services. The main objective is to ensure that the clinic operates safely while COVID-19 restrictions are in place and to improve its providers’ utilization rate. The model simulates people’s movement in the clinic, monitors the congestion level in four common areas, and identifies the peak hours during a day. We also study various overbooking and telehealth policies to overcome high cancelation or no-show rates and low utilization for providers. Simulation results using AnyLogic have helped the management decide to reopen the in-person services during the COVID-19 pandemic based on the safe congestion level demonstrated by the simulation. Insights on optimal overbooking and telehealth policies can shed a broader light on other healthcare organizations. History: This paper was refereed.

Published: August 2023

AimsThe standard of wide tumour-like resection for chronic osteomyelitis (COM) has been challenged recently by adequate debridement. This paper reviews the evolution of surgical debridement for long bone COM, and presents the outcome of adequate debridement in a tertiary bone infection unit.MethodsWe analyzed the retrospective record review from 2014 to 2020 of patients with long bone COM. All were managed by multidisciplinary infection team (MDT) protocol. Adequate debridement was employed for all cases, and no case of wide resection was included.ResultsA total of 53 patients (54 bones) with median age of 45.5 years (interquartile range 31 to 55) and mean follow-up of 29 months (12 to 59) were included. In all, ten bones were Cierny-Mader type I, 39 were type III, and five were type IV. All patients were treated with single-staged management, except for one (planned two-stage stabilization). Positive microbial cultures grew in 75%. Overall, 46 cases (85%) had resolution of COM after index procedure, and 49 (90.7%) had resolution on last follow-up. Four patients (7%) underwent second surgical procedure and six patients (11%) had complications.ConclusionWe challenge the need for wide tumour-like resection in all cases of COM. Through detailed preoperative evaluation and planning with MDT approach, adequate debridement and local delivery of high concentration of antibiotic appears to provide comparable outcomes versus radical debridement.Cite this article: Bone Jt Open 2023;4(8):643–651.
Global, regional, and country-level cost of leptospirosis due to loss of productivity in humans
Authors: Agampodi Suneth , Gunarathna Sajaan , Lee Jung-Seok , Excler Jean-Louis 
Published: August 2023

BackgroundLeptospirosis, a prevalent zoonotic disease with One Health priority and a disease of poverty, lacks global economic burden estimates. This study aims to determine the global, regional, and country-level cost of leptospirosis due to loss of productivity.Methodology/principal findingsThe cost of leptospirosis due to loss of productivity (referred to as productivity cost hereafter) was estimated by converting the disability-adjusted life years (DALYs) lost due to leptospirosis to a monetary value using the per capita gross domestic product (GDP). The country-specific DALYs lost were obtained from the global burden of leptospirosis study published previously. Non-health GDP per capita (GDP- per capita health expenditure) was used for the cost conversion of DALYs. Country-specific GDP and health expenditure data were obtained from the World Bank data repositories. Estimates were done using both nominal and international dollars.The estimated global productivity cost of leptospirosis in 2019 was Int$ 29.3 billion, with low and high estimates ranging from Int$ 11.6 billion to 52.3 billion. China (Int$ 4.8 billion), India (Int$ 4.6 billion), Indonesia (Int$ 2.8 billion), Sri Lanka (Int$ 2.1 billion), and the United States (Int$ 1.3 billion) had the highest productivity cost due to leptospirosis. Eight out of 10 countries with the highest burden were in the Asia-Pacific region. In addition, lower-middle-income countries had an annual productivity cost of Int$ 13.8 billion, indicating that the disease is poverty-related.ConclusionAlthough significant, the cost estimate due to loss of productivity is merely a fraction of the overall economic burden of this disease, which also includes other direct, indirect, and intangible costs. The existing partial estimates of the different components of economic cost suggest a profound economic burden that demands the inclusion of leptospirosis in the global health agenda for comprehensive disease control and prevention efforts, including vaccine development.

BackgroundDespite evidence of depression among mothers of children with cancer, there appears to be a lack of studies or concern regarding factors associated with depression among these mothers.ObjectiveTo review the factors associated with depression among mothers of children with cancer.MethodPubmed, Medline, Cochrane, CINAHL, Psychology, and Behavioural Sciences Collection, and Academic Search Complete were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies published between 2010 to 2022 on the associated risk factors of depression among mothers of children with cancer. The keywords used included mothers OR maternal’ AND ‘Child*’ AND ‘cancer OR tumo*r OR neoplasm’ AND ‘factors OR facilitators AND barriers OR predictors OR determinants AND ‘depression’. Selected studies were evaluated by quality assessment.ResultFive articles fulfilled the eligibility criteria. The factors associated with depression among mothers of children were socio-demographic risk factors (marital status, education level, annual income, child cancer diagnosis), and stress factors (caregiving stress, cancer-related stress, general stress). There were other factors associated with depression that act as mediators along the process which were emotion-focused coping and perceived social support.ConclusionBesides the commonly reported socio-demographic risk factors (marital status, education level, and annual income), other factors include stress factors (caregiving stress, cancer-related stress, and general stress). Furthermore, emotion-focused coping and perceived social support act as mediators along the process. More studies are warranted to explore depression among these mothers to ensure the most appropriate and effective preventive measures.

Published: August 2023

Objectives
The self-administered version of the Mediterranean Diet Scale (MDS) has been developed to test the inherent characteristics of this dietary pattern in a quick and simple way, due to the need of this assessment in the clinical and research setting. This study aimed to translate and psychometrically validate the self-administered MDS in Arabic (CRBS-A).

Methods
The original (English) version was originally translated to Arabic, followed by back-translation. Next, 10 healthcare providers, followed by 10 cardiovascular disease (CVD) patients rated the face and content validity (CV) of materials, providing input to improve cross-cultural applicability. Then, 200 patients from Saudi Arabia completed the questionnaire, of which factor structure, internal consistency, criterion and construct validity were assessed.

Results
Content and face validity was supported based on experts and patients’ reviews (ranges: CV scores 0.9–1.0/1.0 and clarity 3.5 to 4.5/5). Minor edits were made. Subsequent factor analysis revealed 4 factors consistent with the original version of the instrument, all internally consistent. Total CRBS-A α was 0.74. Criterion validity was confirmed by the significantly higher scores in patients who participated in CR. Construct validity was also established by significant associations between MDS scores and monthly family income, having the diagnosis of acute coronary syndrome or with a history of valve repair or replacement, being obese or having dyslipidemia.

Conclusions
Overall, these results confirm the validity and reliability of the MDS in Arabic-speaking patients.
Estimating the causal effects of work-related and non-work-related stressors on perceived stress level: A fixed effects approach using population-based panel data
Authors: Larsen Finn Breinholt , Lasgaard Mathias , Willert Morten Vejs , Sørensen Jes Bak 
Published: August 2023

Objectives
Prolonged or excessive stress can have a negative impact on health and well-being, and stress therefore constitutes a major public health issue. A central question is what are the main sources of stress in contemporary societies? This study examines the effects of work-related and non-work-related stressors and perceived social support on perceived stress within a causal framework.

Methods
Panel data were drawn from two waves (2013 and 2017) of the population-based health survey "How are you?" conducted in the Central Denmark Region. The analytical sample comprised 9,194 subjects who had responded to both surveys. Work-related and non-work-related stressors included major life events, chronic stressors, daily hassles and lack of social support. Perceived stress was measured with the 10-item Perceived Stress Scale (PSS). Data were analysed using fixed effects regression in a fully balanced design.

Results
The largest effects on PSS were seen in own disease, work situation and lack of social support. Other stressors affecting the perceived stress level were financial circumstances, relationship with partner, relationship with family and friends, and disease among close relatives. Most variables had a symmetrical effect on PSS.

Conclusions
The results point to the need for comprehensive policies to promote mental health that span life domains and include both the individual and the group as well as organizational and societal levels. The study indicates that there are multiple potential entry points for stress prevention and stress management. However, it also shows that disease, work situation and social support weigh heavily in the overall picture. This points to the healthcare system and workplace as key institutional venues for action.
Existence of minimizers for the SDRI model in 2d: Wetting and dewetting regime with mismatch strain
Authors: Kholmatov Shokhrukh Y. , Piovano Paolo 
Published: August 2023

Abstract
The model introduced in [45] in the framework of the theory on stress-driven rearrangement instabilities (SDRI) [3, 43] for the morphology of crystalline materials under stress is considered. As in [45] and in agreement with the models in [50, 55], a mismatch strain, rather than a Dirichlet condition as in [19], is included into the analysis to represent the lattice mismatch between the crystal and possible adjacent (supporting) materials. The existence of solutions is established in dimension two in the absence of graph-like assumptions and of the restriction to a finite number m of connected components for the free boundary of the region occupied by the crystalline material, thus extending previous results for epitaxially strained thin films and material cavities [6, 35, 34, 45]. Due to the lack of compactness and lower semicontinuity for the sequences of m-minimizers, i.e., minimizers among configurations with at most m connected boundary components, a minimizing candidate is directly constructed, and then shown to be a minimizer by means of uniform density estimates and the convergence of m-minimizers’ energies to the energy infimum as

m
→
∞

{m\to\infty}

. Finally, regularity properties for the morphology satisfied by every minimizer are established.

Abstract
The article presents a new edition of P.Berl.Bibl. 6 (= SB I 423), which appears to be an acknowledgement of receipt of a leased ammokopregon ship. It is argued that the ship was used for collecting silt fertiliser in the marshy parts of the Nile near Memphis, and that the name of the ship, Myrismos, is a Greek epithet of the Memphite god of the water lily and of fragrance, Nefertem.

Abstract
Starting from a re-interpretation of the reading KEΡATAYΛEI at line 17 of P. Matr. inv. 44+119, this article compares the content of the Madrid mime papyrus with a famous scene of Menander’s Theophoroumene which also relates to the performance of rituals connected with Phrygian cults.
Il “viaggio solitario” come luogo d’incontro con il soprannaturale. Un topos letterario in P.Oxy. XI 1368 (Lolliano, Phoinikika) e nel primo capitolo del Pastore di Erma
Authors: Castelli Emanuele 
Published: August 2023

Abstract
Comparison of the content of P.Oxy. XI 1368, which preserves a fragment of Lollianus’ Phoinikika, with a passage from the first chapter of the Shepherd of Hermas. The similarities between the two passages show that Lollianus and Hermas adopt the same literary motif, namely the topos of the solitary journey, in order to narrate encounters with spirits or other supernatural realities. The same topos is employed in Philostratus’ Life of Apollonius of Tyana IV, 25. Hermas, however, christianizes the motif through some additions.
Nouvelles perspectives dans l’interprétation du signe mélodique en forme de V dans le papyrus musical de Ménandre (P.Oxy. LIII 3705)
Authors: Kaisin Mathilde 
Published: August 2023

Abstract
With the fourteen musical papyri that have been discovered in situ, all dating from the Roman period, the city of Oxyrhynchus, in Middle Egypt, constitutes the largest reservoir of ancient “scores” found up to now. By their fragmentary appearance, these papyri are often difficult to interpret and raise many questions, especially as to the interpretation of certain musical signs they contain. This article aims to open up new perspectives in the study of an enigmatic V-shaped melodic sign in the musical papyri of Menander (P.Oxy. LIII 3705).
Militärdiplome, überliefert durch papyrologische Dokumente
Authors: Eck Werner 
Published: August 2023

Abstract
In the so-called epikrisis documents, soldiers sometimes also presented their citizenship diplomas. From these, an extract in Greek was occasionally included in the administrative records. These have not been considered as fully valid documentation in the collections of military diplomas until now. Therefore, the partially preserved diplomas were not included in the collections. Here three such cases are retranslated into the original Latin form.

The Provenance of the Robinson and Mississippi Papyri
Authors: Sharp Daniel B. 
Published: August 2023

Abstract
The Robinson Papyri and the Mississippi Papyri were first introduced by William H. Willis at the ninth International Congress of Papyrology. This article deconstructs Willis’s paper and, using archival evidence, reconstructs the provenance and makeup of these two distinct collections, moving past Willis’s presentation to provide the history of both collections since 1958. The author brings to light the cross contamination and mislabeling between the Robinson and Mississippi Papyri collections caused by Willis and argues that some pieces published as “Robinson Papyri” are parts of other collections.

Published: August 2023

Abstract
Radiation and nuclear technologies have side effects in addition to their important applications, so appropriate shields must be used to protect users and the public from high doses as a result of exposure to this radiation. In this work, the attenuation coefficients for polyester composites doped with waste iron filings (IFs) were studied. Six samples of different IF concentrations were manufactured, namely, Poly, Poly-IF20, Poly-IF30, Poly-IF40, Poly-IF50, and Poly-IF60 (where Poly-IF60 represents 40% polyester and 60% IF). We measured the attenuation factors using high purity germanium (HPGe)-detector along with three radioactive sources 241Am (emitting energy of 0.06 MeV), 137Cs (emitting energy of 0.662 MeV), and Co-60 (emitting energy of 1.173 and 1.333 MeV). We compared the linear attenuation coefficient (LAC) obtained by theoretical (i.e., XCOM software) and experimental (i.e., HPGe-detector) approaches for the prepared polyester composites at various photon energies (0.060, 0.662, 1.173, and 1.333 MeV). The greatest difference between the LAC values of the samples occurs at 0.060 MeV, where the Poly-IF60 sample has a much greater LAC than the other shields, followed by the Poly-IF50 sample, Poly-IF40 sample, and so on until the pure polyester shield. Specifically, their values are equal to 0.245, 0.622, 0.873, 1.187, 1.591, and 2.129 cm−1 for Poly, Poly-IF20, Poly-IF30, Poly-IF40, Poly-IF50, and Poly-IF60, respectively. We calculated the transmission factor (TF) and the radiation shielding efficiency (RSE), and found that the TF for Poly-IF30 is equal to 28.82%, 77.94%, 82.75%, and 83.75% at 0.060, 0.662, 1.173, and 1.333, respectively, while its RSE is equal to 82.57%, 24.00%, 18.80%, and 17.72%, respectively. The fast neutron removal cross-section (FNRC) of the polyester samples was calculated and the values increase when more Ifs are added to the samples. More specifically, the FNRC values are equal to 0.095, 0.100, 0.103, 0.107, 0.110, and 0.113 cm−1 for Poly, Poly-IF20, Poly-IF30, Poly-IF40, Poly-IF50, and Poly-IF60, respectively.

Some results on Seshadri constants of vector bundles
Authors: Biswas Indranil , Hanumanthu Krishna , Misra Snehajit 
Published: August 2023

Abstract
We study Seshadri constants of certain ample vector bundles on projective varieties. Our main
motivation is the following question: Under what conditions are the Seshadri constants of ample vector
bundles at least 1 at all points of the variety? We exhibit some conditions under which this
question has an affirmative answer. We primarily consider ample bundles on projective spaces
and Hirzebruch surfaces. We also show that Seshadri constants of ample vector bundles can be
arbitrarily small.

Authors: Toshtemirov Bakhodirjon 
Published: August 2023

Abstract
In the present paper, the unique solvability of the direct and inverse source problems for the pseudo-parabolic equation involving the bi-ordinal Hilfer fractional derivative and 2D Landau Hamiltonian operator is considered. Applying the Fourier analysis for the operator Landau Hamiltonian, the theorems of uniqueness and existence of solutions to direct and inverse source problems are proved. In the investigation of the inverse source problem, we have used the value of unknown function at the final time in order to find the right-hand side of the equation. It is also presented the stability result of the inverse problem.
