Abstract

Purpose
Supervised exercise is a potentially promising supportive care intervention for people with metastatic breast cancer (MBC), but research on the patients’ perspective is limited. The aim of the current focus group study was to gain an in-depth understanding of MBC patients’ perceived barriers, facilitators, and preferences for supervised exercise programs.

Methods
Eleven online focus groups with, in total, 44 MBC patients were conducted in four European countries (Germany, Poland, Spain, Sweden). Main topics of the semi-structured discussions covered attitudes towards participation in supervised exercise programs, perceived facilitators, experienced barriers, and exercise preferences. Interviews were transcribed verbatim, translated into English, and coded based on a preliminary coding framework, supplemented by themes emerging during the sessions. The codes were subsequently examined for interrelations and re-organized into overarching clusters.

Results
Participants had positive attitudes towards exercise, but experienced physical limitations and insecurities that inhibited their participation. They expressed a strong desire for exercise tailored to their needs, and supervision by an exercise professional. Participants also highlighted the social nature of group training as an important facilitator. They had no clear preference for exercise type, but rather favored a mixture of different activities. Flexible training modules were considered helpful to increase exercise program adherence.

Conclusions
MBC patients were generally interested in supervised exercise programs. They preferred group exercise that facilitates social interaction, but also expressed a need for individualized exercise programs. This suggests the relevance to develop flexible exercise programs that are adjusted to the individual’s needs, abilities, and preferences.
What drives horse success at following human-given cues? An investigation of handler familiarity and living conditions

Published: April 2023

AbstractCues such as the human pointing gesture, gaze or proximity to an object are widely used in behavioural studies to evaluate animals’ abilities to follow human-given cues. Many domestic mammals, such as horses, can follow human cues; however, factors influencing their responses are still unclear. We assessed the performance of 57 horses at a two-way choice task testing their ability to follow cues of either a familiar (N = 28) or an unfamiliar informant (N = 29). We investigated the effects of the length of the relationship between the horse and a familiar person (main caregiver), their social environment (living alone, in dyads, or in groups) and their physical environment (living in stalls/paddocks, alternating between paddocks and pastures, or living full time in pastures). We also controlled for the effects of horses’ age and sex. Our results showed that horses’ success rate at the task was not affected by the familiarity of the informant and did not improve with the relationship length with the familiar informant but did increase with the age of the horses. Horses living in groups had better success than the ones kept either in dyads or alone. Finally, horses housed in small paddocks had lower success than those living on pasture. These results indicate that with age, horses get better at following human-given indications regardless of who the human informant is and that an appropriate living and social environment could contribute to the development of socio-cognitive skills towards humans. Therefore, such aspects should be considered in studies evaluating animal behaviour.

Published: April 2023

AbstractPlasmodium vivaxis the most geographically widespread malaria-causing parasite resulting in significant associated global morbidity and mortality. One of the factors driving this widespread phenomenon is the ability of the parasites to remain dormant in the liver. Known as ‘hypnozoites’, they reside in the liver following an initial exposure, before activating later to cause further infections, referred to as ‘relapses’. As around 79–96% of infections are attributed to relapses from activating hypnozoites, we expect it will be highly impactful to apply treatment to target the hypnozoite reservoir (i.e. the collection of dormant parasites) to eliminateP. vivax. Treatment with radical cure, for example tafenoquine or primaquine, to target the hypnozoite reservoir is a potential tool to control and/or eliminateP. vivax. We have developed a deterministic multiscale mathematical model as a system of integro-differential equations that captures the complex dynamics ofP. vivaxhypnozoites and the effect of hypnozoite relapse on disease transmission. Here, we use our multiscale model to study the anticipated effect of radical cure treatment administered via a mass drug administration (MDA) program. We implement multiple rounds of MDA with a fixed interval between rounds, starting from different steady-state disease prevalences. We then construct an optimisation model with three different objective functions motivated on a public health basis to obtain the optimal MDA interval. We also incorporate mosquito seasonality in our model to study its effect on the optimal treatment regime. We find that the effect of MDA interventions is temporary and depends on the pre-intervention disease prevalence (and choice of model parameters) as well as the number of MDA rounds under consideration. The optimal interval between MDA rounds also depends on the objective (combinations of expected intervention outcomes). We find radical cure alone may not be enough to lead toP. vivaxelimination under our mathematical model (and choice of model parameters) since the prevalence of infection eventually returns to pre-MDA levels.
Phenomenology of an In-host Model of Hepatitis C
Authors: Nangue Alexis , Rendall Alan D. 
Published: April 2023

AbstractThis paper carries out an analysis of the global properties of solutions of an in-host model of hepatitis C for general values of its parameters. A previously unknown stable steady state on the boundary of the positive orthant is exhibited. It is proved that the model exhibits Hopf bifurcations and hence periodic solutions. A general parametrization of positive steady states is given and it is determined when the number of steady states is odd or even, according to the value of a certain basic reproductive ratio. This implies, in particular, that when this reproductive ratio is greater than one there always exists at least one positive steady state. A positive steady state which bifurcates from an infection-free state when the reproductive ratio passes through one is always stable, i.e. no backward bifurcation occurs in this model. The results obtained are compared with those known for related models of viral infections.
Climate change vulnerability hotspots in Costa Rica: constructing a sub-national index
Authors: Nawrotzki Raphael J. , Tebeck Marina , Harten Sven , Blankenagel Venya 
Published: April 2023

AbstractFor policies and programs aiming at reducing climate risk, it is important to obtain vulnerability information at the sub-national level to identify hotspots. For the case of Costa Rica, no sub-national climate vulnerability index exists to date. To fill this gap, we constructed a climate vulnerability index at the canton level. We ground our work in the conceptual framework that vulnerability is a function of exposure, sensitivity, and adaptive capacity. Making extensive use of geographic information systems and publicly available data, we constructed 13 spatial layers to reflect the multi-dimensionality of vulnerability. Layers reflect for example, changes in climatic extremes, flood risk, vegetation cover, access to infrastructure (road density) and health services (distance to hospitals), as well as various socioeconomic (wealth level, employment rates, remittances, literacy rate) and demographic (infant mortality) characteristics. Following normalization, we constructed an inverse variance weighted index of canton-level climate vulnerability. We confirmed the validity of our climate vulnerability index through correlation with disaster damage data. We find the strongest climate vulnerability not only in the rural, agricultural producing border cantons (Los Chiles, Matina, Talamanca, Buenos Aires), but also for a few central urban cantons (Tibas, San Jose). Projects and interventions in these hot spot cantons may reduce sensitivity through strengthening hydrological infrastructure and economic development, while adaptive capacity may be improved through addressing barriers of remittance transfer, and via public health programs.

Abstract
Background
There is a need for a non-pharmacological approach to reduce pain and plantar pressure in diabetic peripheral neuropathy (DPN). Matrix Rhythm Therapy (MaRhyThe®) is a therapeutic modality that works on the principle of physiologic rhythmic oscillations of the body cells. This study aimed to evaluate the effect of MaRhyThe® on neuropathic pain and maximum plantar pressure distribution among type 2 diabetes mellitus patients with peripheral neuropathy.

Materials and methods
A total of 33 participants with DPN were recruited for the study based on inclusion criteria. Maximum plantar pressure was recorded using Win-Track 11K005, and the pain score was obtained using a visual analogue scale. Ten sessions of MaRhyThe® were given to all the participants. Outcome measures were evaluated at the baseline and after 10th session. Paired t-test was performed to analyze the changes in outcome measures.

Results
Participants of DPN were recruited with the average age of 64 ± 9 years, and an average duration of diabetes was 14 ± 9 years were included. Results of the present study found significant improvement in neuropathic pain and plantar pressure in post intervention assessment. (p < 0.05)

Conclusion
In the present study, we found that MaRhyThe® is effective in reducing neuropathic pain and maximum plantar pressure in type 2 diabetes mellitus with peripheral neuropathy.
3D DEM model simulation of asphalt mastics with sunflower oil
Authors: Câmara Gustavo , Micaelo Rui , Monteiro Azevedo Nuno 
Published: April 2023

AbstractA three-dimensional particle model, based on the asphalt mastic micro-structure representation following a discrete element model framework, was developed to investigate the influence of sunflower oil (rejuvenator) on the rheological properties of asphalt mastic. Dynamic shear rheometer tests in laboratory, for a frequency range of 0.1–20 Hz and temperatures in a range between 20 and 80 $$^{\circ }$$

∘

C, were carried out in order to assess the viscoelastic behaviour of asphalt mastics containing different oil-to-bitumen content by mass proportions (2.5–20%). Master curves were constructed for two reference temperatures (30 $$^{\circ }$$

∘

C and 50 $$^{\circ }$$

∘

C). Experimental results showed that the increase in sunflower oil content resulted in a progressive decrease in viscosity. However, the rheological behaviour of the mastic containing the highest oil amount could not be properly represented in master curves, indicating that the specimen had a different rheological behaviour when compared with the lower oil contents responses. Numerical simulations of rheometer tests were carried out with an asphalt mastic particle assembly that emulated the experimental procedure. The viscoelastic contacts within the asphalt mastic assembly were simulated with a generalized Kelvin contact model. A calibration procedure was derived based on the fitting of laboratory data. The simulations were shown to have a good agreement with laboratory values. The average errors for the dynamic shear modulus and phase angle were 3.4% and 4.0%, respectively, considering both temperatures of analysis. Finally, a considerable improvement was accomplished in comparison with the numerical response obtained with the often-used Burgers model.
Unmet needs on the current medical management of Cushing’s syndrome: results from a Delphi panel of Italian endocrinologists
Authors: Pivonello R. , Scaroni C. , Polistena B. , Migliore A. , Giustina A. 
Published: April 2023

Abstract
Background
Cushing’s syndrome (CS) is a rare clinical condition caused by excessive cortisol secretion from adrenal glands. CS is associated with increased mortality and morbidity; therefore, a prompt diagnosis and an effective therapeutic approach are strongly necessary to improve the patient’s clinical management. The first-line treatment for CS is surgery, while medical treatment has historically played a minor role. However, thanks to the availability of novel compounds, the possibility of improving hypercortisolism control using different drug combinations emerged.

Purpose
No absolute recommendations are available to guide the therapeutic choice for patients with CS and, consequently, the awareness of unmet needs in CS management is growing. Although new data from clinical trials are needed to better define the most appropriate management of CS, an expert consensus approach can help define unmet needs and optimize the current CS management and treatment.

Methods
Twenty-seven endocrinologists from 12 Italian regions, working among the main Italian referral centers for hospital endocrinology where they take care of CS patients, were involved in a consensus process and used the Delphi method to reach an agreement on 24 statements about managing CS patients.

Results
In total, 18 statements reached a consensus. Some relevant unmet needs in the management of CS were reported, mainly related to the lack of a pharmacological treatment successful for the majority of patients.

Conclusion
While acknowledging the difficulty in achieving complete disease control, a significant change in CS management requires the availability of medical treatment with improved efficacy and safety over available therapeutic options at the time of the current study.
Free and Low-Cost Aerial Remote Sensing in Archaeology
Authors: Lindsay Ian , Mkrtchyan Arshaluys 
Published: April 2023

ABSTRACTRecent years have seen the rapid expansion of airborne and spaceborne remote-sensing products adopted by archaeologists for interpreting ancient landscapes and managing heritage resources. A growing and increasingly specialized literature attests to the promise and availability of commercial and publicly funded satellite imagery, as well as UAV-mounted sensors across a range of resolutions and price points. In the South Caucasus (including the countries of Armenia, Azerbaijan, and Georgia), a growing commitment to landscape approaches in archaeology is stimulating the adoption of satellite remote sensing as an important new tool for identifying and managing archaeological resources while tracing the impact of historic land-use alterations in survey areas. Nevertheless, budgetary challenges and a lack of training opportunities among international partners and heritage organizations outside of the funding streams of large academic institutions can lead to widening technological gulfs in the discipline that reinforce colonial relationships. Building on recent technical articles covering specific imagery datasets, this article aims to address this by providing a general review of free or low-cost remotely sensed datasets available to archaeologists, with the aim of broadening awareness of these important tools and their vocabularies, and illustrating them with recent published examples from the South Caucasus.
Disaffected but Efficacious: Why People Join Populist Radical Right Parties
Authors: Ammassari Sofia 
Published: April 2023

AbstractThe number of grassroots members of populist radical right (PRR) parties is on the rise, in contrast to the trend of membership decline in mainstream parties. While scholars have explained this by studying PRR parties' organizational strategies, I focus on party members and ask: Why do people join PRR parties? To answer this, I look not only at motivations, which is the dominant framework in party membership studies, but also at triggers – factors activating those motivations. Drawing on collective action scholarship, I argue that grievances and efficacy can work as triggers for joining PRR parties. Using interviews with 82 members of the Bharatiya Janata Party, the League in Italy and the Sweden Democrats, I uncover three elements in the path to PRR party membership: disaffection, affiliation and action. As well as questioning established narratives on why citizens join parties, my findings provide a novel theoretical framework to investigate this form of political participation.
Motivating a Scientific Modeling Continuum: The Case of “Natural Models” in the COVID-19 Pandemic
Authors: Nefdt Ryan M. 
Published: April 2023

AbstractThe COVID-19 global pandemic had a profound effect on scientific practice. During this time, officials crucially relied on the work done by modelers. This raises novel questions for the philosophy of science. Here I investigate the possibility of 'natural models' in predicting the SARS-Cov-2 virus’s trajectory for epidemiological purposes. I argue that to the extent that these can be considered scientific models, they support the possibility of a continuum from scientific models to natural models differing in artifactual commitment. In making my case, I draw from work on both model organisms and natural experiments as well as recent work in epidemiology.
THE LATIN ORIGINS OF A BILINGUAL LETTER COLLECTION (SPECIMINA EPISTVLARIA=P.BON.5)
Authors: Gitner Adam , Scappaticcio Maria Chiara 
Published: April 2023

AbstractP.Bon.5 preserves the only known collection of ancient Latin model letters, accompanied by a Greek translation. This article argues that the Latin is the primary version and dates the composition to before the early third century. Comparisons with other model letter collections, principally ps.-Demetrius’Epistolary Typesand ps.-Libanius’Epistolary Styles, locate the text within a wider literary genre. A new reconstructed text is provided in the Appendix at the end of this article.
Class Trips beyond Borders: Reimagining the Nation through State-Sponsored Heritage Tourism
Authors: Molnár Virág 
Published: April 2023

AbstractThe article explores how cross-border heritage tourism is promoted in public schools to reimagine Hungary as an ethnically homogeneous nation by incorporating ethnic kin communities that live in neighboring countries. Cross-border heritage tourism has long served to establish strong ties to ethnic diaspora communities that live beyond the territorial borders of the nation-state. National borders in Central and Eastern Europe were repeatedly redrawn across ethnic groups over the twentieth century. Heritage tourism remains a key cultural and economic practice that symbolically questions current national borders and aims to increase the viability of ethnic enclave economies in countries where the given ethnic group is a minority. The article focuses on a large-scale student travel program that was launched by the Hungarian government in 2010, the year that marked the start of a brisk populist turn in Hungarian politics. The program provides funding to public school students for organized class trips to areas of neighboring countries (Romania, Slovakia, Serbia, Croatia, and Ukraine) that belonged to the Hungarian state before World War I. It shows how the Hungarian government mobilizes the public education system to foster a narrow and exclusionary ethnic understanding of cultural membership by selectively overemphasizing Hungarian heritage in regions that have had multi-ethnic, multi-religious, and multicultural histories for centuries. This project extends research on identity-based heritage tourism to show how it has become an integral part of the propaganda toolkit of populist governments.
“Our Adriatic”: Comment on Forum on Adriatic Tourism
Authors: Ballinger Pamela 
Published: April 2023

AbstractThis short piece comments on the articles presented in the forum on Adriatic tourism and their analyses of competing historical claims to “our Adriatic.” The comment focuses on questions raised about ownership of the sea and the Adriatic's borders of belonging. While sovereignty over areas of the Adriatic has proven an enduring diplomatic issue in both the twentieth and twenty-first centuries, the forum authors instead consider claims by different types of actors: tourists (particularly Czech tourists who claimed a special relationship between Czechs and their South Slav “brothers”); investors in hotels and related infrastructure; socialist Yugoslav tourism planners; and environmentalists concerned with issues of pollution. In tracing out tensions in the agendas of hosts and visitors, as well as planners and scientists, the forum's essays measure and map the socio-ecological metabolism of the modern eastern Adriatic.
