Authors: Barbanti Roberto , Bourdiol Aurélien , Celedón Gustavo , Del Ghingaro Ulysse , Reyna Alejandro , Schaub Stéphan , Solomos Makis , Tercero Jordi
Published: November 2024

En novembre 2022, un groupe de musicologues et de musiciens-chercheurs s’est retrouvé dans la ville argentine de Santa Fe dans le cadre du projet INNOVART « Les usages du son. Approches créatives, théoriques et technologiques du field recording » pour un travail de recherche partant d’enregistrements sonores. L’idée initiale, qui était d’ausculter le fleuve Paraná aux alentours de Santa Fe – autrement dit, faire état de cet écosystème singulier par l’écoute et les technologies de l’écoute –, s’est enrichie progressivement et finalement la mission s’est déroulée sur trois sites : les îles du Paraná, appelées la isla dans la région, le quartier de La Boca en périphérie de Santa Fe et la prison de la ville de Coronda située le long du Paraná. Les îles du Paraná ont été étudiées grâce à deux voyages en bateau ainsi qu’une invitation chez un habitant. Le quartier de La Boca a été visité en participant à un projet de tourisme communautaire organisé par les habitants. Quant à la prison de Coronda, le groupe s’y est rendu avec pour guides deux anciens détenus politiques de la dictature de Videla. Pour chaque site, des enregistrements sonores ont été réalisés ainsi que des entretiens autour du vécu sonore des territoires avec les habitants. Afin de mieux rendre compte de ce travail, cet article incorpore une sélection d’enregistrements, d’extraits d’entretiens et d’images. Le texte est structuré en une introduction théorique, suivie d’une partie méthodologique, puis de cinq grandes parties qui rendent compte des expériences recueillies selon une approche spécifique du son à chaque fois différente : morphologique, quotidienne, de l’attention, qualitative et politique ; la conclusion pointe le besoin d’une écoute écosophique et propose une réflexion sur l’acte d’enregistrer.
Voir-savoir, ou les tribulations du regard scientifique
Authors: Bouldoires Alain
Published: November 2024

Notre propos consiste à discuter des outils de visualisation de l’activité savante et au-delà, du regard qui fait sens dans ce domaine. En explorant les techniques visuelles mises en œuvre par le monde scientifique, cette étude s’inscrit dans une écologie du savoir qui considère la culture savante dans sa matérialité, c’est-à-dire dans le milieu propre depuis lequel les acteurs agissent. L’évolution épistémologique des méthodes visuelles nous apprend ainsi à mieux comprendre le rapport des scientifiques au concept d’objectivité. Cette histoire n’est ni linéaire, ni simple. Elle a connu divers régimes de visualisation de la connaissance qui sont autant de témoignages de la relativité du regard scientifique.
Visual transcription
Authors: Geenen Jarret , Matelau-Doherty Tui , Norris Sigrid
Published: November 2024

The communication and language sciences have decidedly taken a multimodal turn and a proliferation of work in previously language-dominated fields is focusing on the contribution of non-verbal communicative modes in social interaction. While this has proven empirically and theoretically fruitful, it throws an additional kink in an already complicated issue: transcription practices and the interpretive and representational process accompanying said practices. In this article, we review and champion a methodological framework that provides analytical tools and a transcription protocol for the generation of visual transcripts. Visual transcription, we contest, is far more congruent with the multimodal ethos and we both detail the method while applying it to a data segment from a larger project investigation teamwork and collaborative problem-solving in dyadic videoconferencing interactions. The analytical focus on action coupled with the accompanying transcription method reveals complex and fluctuating distributions of attention and interactional awareness. Non-verbal actions reveal contributions to the task at hand which are not realized in talk and the analysis details an intricate ebb and flow of attentional orientations which are realized through non-verbal means.
Les images au labo
Authors: Drouet Jeanne
Published: November 2024

Cet article propose d’observer et d’analyser, à l’échelle d’un laboratoire de sociologie, comment les images sont partie prenante de l’activité de recherche. L’histoire d’une enquête menée au Centre Max Weber est d’abord retracée dans un double objectif : expliciter les principaux enjeux d’une telle entreprise et entamer la description des pratiques de sociologies visuelles qui se déploient en son sein. S’ensuit la présentation des résultats de l’enquête par questionnaire et de la cartographie de pratiques qui en est issue. Il est enfin question des apports de cette étude à une réflexion plus générale sur les méthodes visuelles, à savoir la mise en visibilité de pratiques plus souterraines (peu visibles dans les espaces « vitrines » de la recherche).
Apollinaire, ou la double tentation de la solitude et de l’autre
Authors: Bevilacqua Luca
Published: November 2024

Sensible aux divers appels du passé (la culture classique, le Moyen Âge, la poésie symboliste) et du présent (l’avant-garde, la presse, la publicité), Apollinaire nous révèle, tout au long de sa production, une grande richesse non exempte d’ambiguïtés. Outre le célèbre antagonisme entre l’Ordre et l’Aventure, une autre contradiction évidente concerne le public auquel il s’adresse : si certains de ses poèmes sont très accessibles et empreints de musicalité, dans d’autres cas, il semble écrire uniquement pour des lecteurs cultivés. Apollinaire souligne souvent sa condition de poète-prophète et la solitude de sa quête, tout en assumant, paradoxalement, un rôle de médiateur culturel à travers de nombreux articles sur la contemporanéité. L’étude présentée ici tente d’analyser ces contradictions, en particulier celle entre la recherche de l’approbation d’autrui (la tentation de l’autre) et l’exigence d’intimité (la tour d’ivoire).
La tour d’ivoire : sixième tentation de La Fontaine ?
Authors: Corradi Federico
Published: November 2024

Selon Giraudoux, La Fontaine aurait dû surmonter cinq tentations – la vie bourgeoise, les femmes, le monde, etc. – avant de découvrir sa véritable vocation de fabuliste. La tour d’ivoire serait-elle une sixième tentation qui l’aurait séduit un moment avant la chute de Fouquet ? La carrière de La Fontaine serait alors partagée en deux époques : l’époque du désengagement galant et l’époque de la découverte, avec les Fables, d’une poésie « impure » qui brasse les savoirs et dialogue avec la société de son temps. Cette perspective chronologique n’est pas fausse, mais elle est à nuancer. Il s’agit moins d’une évolution que d’une double postulation qui anime le parcours de La Fontaine tout au long de sa carrière, partagée entre légèreté et esprit de sérieux, culte des formes et innutrition savante, tentation de l’enfermement et ouverture au monde.
Engagement et désengagement dans les paratextes des traductions théâtrales du XVIe siècle
Authors: Speziari Daniele
Published: November 2024

Cette contribution étudie les paratextes (préfaces, épîtres dédicatoires, avis aux lecteurs etc.) de nombreuses traductions théâtrales publiées en France au XVIe siècle, dans le but de montrer que, si la composition de la majorité de ces textes était animée par des finalités engagées, de caractère didactique ou pédagogique, l’idée de désengagement était tout de même ancrée dans l’esprit d’un certain nombre de traducteurs. Ces derniers, en refusant la conception de traduction comme service, ont recherché leur propre « profit » individuel et se sont enfermés dans une « tour d’ivoire » qui incarne tantôt un manque d’ambition plus ou moins absolu, tantôt une forte ambition d’expérimenter avec la langue et de s’imposer comme des pionniers.

Published: November 2024

Trois traducteurs, Luca Bevilacqua, Giuseppe Girimonti Greco et Giuseppe Zuccarino, se rencontrent autour de quatre traductions inédites de Michaux. Dans la diversité de leurs approches, ils adoptent diverses solutions : chacune met en valeur le caractère hétérogène et hybride des textes, en vers et en prose, du poète franco-belge. Les quatre traductions proposées ici sont précédées d’une introduction dans laquelle Luca Bevilacqua fait le point sur la diffusion italienne de Michaux et présente sa propre traduction de « Je suis né troué » et de « Nous autres ». Celles d’« Une vie de chien » et de « The Thin Man » sont commentées par leurs traducteurs respectifs. En annexe la transcription de la traduction par Franco Calamandrei d’« Une vie de chien ».
Représenter la représentation : les assemblées de l’Antiquité, miroirs de la Révolution à la scène
Authors: Avocat Éric
Published: November 2024

La présence de l’Antiquité dans l’imaginaire politique de la Révolution a trouvé un puissant vecteur sur les scènes de théâtre, où les sujets grecs et romains entrent en résonance avec l’exaltation de l’héroïsme patriotique et républicain. Ils sont aussi en prise sur l’événement majeur que constitue l’émergence des assemblées parlementaires, que les citoyens spectateurs appréhendent et jugent de manière plus aiguë au prisme de la scène. Cependant, si les créations dramatiques de la période font la part belle aux assemblées du peuple comme aux sénats oligarchiques qui ont fait l’histoire de Rome et de la Grèce, plutôt qu’aux assemblées modernes ou contemporaines, c’est aussi parce qu’elles rejouent les aléas de la naissance des institutions représentatives et répondent au sentiment de fragilité qui hante les acteurs révolutionnaires face à leur œuvre politique.
Entre peinture et scène : expérimentations néoclassiques dans le décor de théâtre, le cas d’Ignazio Degotti (1758-1824)
Authors: Cazzato Elisa
Published: November 2024

Ignazio Degotti (1758-1824), né à Turin, peintre de décors actif à Paris à partir de 1790, est chef décorateur du Théâtre de l’Opéra entre 1795 et 1822. Hors de la scène théâtrale, il collabore avec Jacques-Louis David (1748-1825). Les premiers contacts documentés entre Degotti et David remontent au début de 1800, bien qu’on puisse dater une première rencontre entre les deux artistes à l’année 1784, lorsqu’ils séjournaient tous deux à Rome. L’époque d’activité de Degotti coïncide avec la pleine maturité de l’esthétique néoclassique dans les arts. Cette contribution considère de quelle façon, au tournant du XIXe siècle, se développa un véritable décor néoclassique, strictement dans la lignée des théories esthétiques de l’époque, ou si, plus simplement, le décor au théâtre suivit une phase d’expérimentation en se servant de l’art antique. L’article explore les détails du rapport entre Degotti et David, tout en démontrant comment la peinture et le théâtre ont été un terrain fertile d’expérimentation artistique et de liens interdisciplinaires entre l’Italie et la France.
Camille Lemonnier poète en prose ou le portrait de l’artiste en faussaire
Authors: Baldini Alessio
Published: November 2024

À partir de l’étude d’un groupe de poèmes en prose retrouvés dans le Musée des deux mondes et n’ayant pas été publiés en volume, l’objectif de cet article est de situer Camille Lemonnier dans le paysage que dessine le poème en prose français dans la seconde moitié du XIXe siècle. La démarche scientifique de cet essai est donc double : d’une part documentaire, car il entend rendre compte d’une production littéraire peu connue, voire rare ; d’autre part critique, car il vise à étudier les tendances stylistiques et rhétoriques de celle-ci à l’aune du motif artistique qui s’y greffe.

Using Video Feedback to Create Faculty Presence in the Virtual Classroom
Authors: Streit Mary , Levin Madia , Harris Alycia L.
Published: November 2024

The inherent transactional distance in online learning often leads to student feelings of disengagement, disconnection, and anxiety. The increasing reliance on technology exacerbates this issue by eliminating key elements of human communication such as facial expressions and tone of voice. To mitigate these issues, faculty are increasingly turning to video feedback which can enhance the sense of faculty presence. This approach aims to replicate aspects of in-person communication vital to fostering a connected, engaging, and supportive learning environment. This chapter explores the efficacy of video feedback in establishing social, teaching, and cognitive presence as described by the Community of Inquiry Model. Through an examination of recent research on faculty perceptions, the chapter underscores the potential of video feedback to foster a more interactive, engaging, and humanized online learning environment, while also highlighting the need for further faculty training and best practices.

Flipped Classroom Approach to Incorporate MOOCs as Micro-Credentials Into Higher Education
Authors: Atas Amine Hatun
Published: November 2024

Micro-credentials, which signify the attainment of particular skills, have attracted considerable interest due to their adaptability, alignment with industry requirements, and congruence with lifelong learning endeavors. While encompassing various types, micro-credentials are often linked with Massive Open Online Courses (MOOCs). Despite the increasing number of MOOCs and the rising enrollment of students acquiring micro-credentials, there is a challenge regarding the recognition of these micro-credentials within formal educational contexts. At this stage, the Flipped Classroom (FC), which involves both online and in-class phases, could present a suitable approach for integrating micro-credentialing into formal educational contexts under the guidance of course instructors. Accordingly, the aim of this chapter is to advance a conceptual proposal for acknowledging and recognizing MOOCs as a source of micro-credentials within the context of higher education environments while accounting for the intricate interactions among micro-credentialing, MOOCs, and the FC approach.

Enhancing adherence to diet therapy and fluid restrictions in hemodialysis patients: a study using the information-motivation-behavioral skills model
Authors: S Hi Arsan Zulhikmah , Sjattar Elly Lilianty , Arafat Rosyidah
Published: November 2024

A common issue faced by many patients undergoing the Hemodialysis (HD) is non-compliance with diet therapy and fluid intake limitation. To address this issue, the educational model aims to change the required behavior of patients. The Information Motivation Behavior Skill (IMB) model is a behavioral intervention designed to promote behavior change in various situations. This study sought to assess how well the IMB educational model supports adherence to diet therapy and fluid restrictions in patients receiving HD. This study was carried out in the HD departments. It was a quasi-experimental study featuring a pretest and posttest design with a control group involving 80 patients. The participants were split into an intervention group that received education based on the  Information Motivation Behavior Skill model(n = 40) and a control group that received standard hospital education according to standard operating procedures (n = 40). After eight dialysis sessions over a period not exceeding four weeks, participants were evaluated for adherence to diet therapy and fluid restrictions. Significant change in diet therapy and fluid restriction in the intervention group with the P-value of 0.001. In the control group, there is a significant change in diet therapy and fluid restriction with P-values of 0.005 and 0.002. There are no significant differences between the intervention and control groups in the pre-test for diet therapy and fluid restriction, with P-values of 0.221 and 0.146. However, in the post-test, there are significant differences between the intervention and control groups, with a P-value of 0.001. The Information Motivation Behavior Skill model of education shows great promise in promoting adherence to diet therapy and fluid restrictions.

The findings highlight the importance of integrating cutting-edge technologies and certification schemes to build a robust and transparent meat supply chain.
An epidemical model with nonlocal spatial infections
Authors: Yang Su , Chu Weiqi , Kevrekidis Panayotis
Published: November 2024

The SIR model is one of the most prototypical compartmental models in epidemiology. Generalizing this ordinary differential equation (ODE) framework into a spatially distributed partial differential equation (PDE) model is a considerable challenge. In the present work, we extend a recently proposed model based on nearest-neighbor spatial interactions by one of the authors towards a nonlocal, nonlinear PDE variant of the SIR prototype. We then seek to develop a set of tools that provide insights for this PDE framework. Stationary states and their stability analysis offer a perspective on the early spatial growth of the infection. Evolutionary computational dynamics enable visualization of the spatio-temporal progression of infection and recovery, allowing for an appreciation of the effect of varying parameters of the nonlocal kernel, such as, e.g., its width parameter. These features are explored in both one- and two-dimensional settings. At a model-reduction level, we develop a sequence of interpretable moment-based diagnostics to observe how these reflect the total number of infections, the epidemic’s epicenter, and its spread. Finally, we propose a data-driven methodology based on the sparse identification of nonlinear dynamics (SINDy) to identify approximate closed-form dynamical equations for such quantities. These approaches may pave the way for further spatio-temporal studies, enabling the quantification of epidemics.
Vaginal Bleeding in an Infant due to Extragonadal Germ Cell Tumor: A Case Report with Review of Literature
Authors: Assadi Ayesha Amanath , Maiti Dipshikha , Bandyopadhyay Debasish
Published: November 2024

Background:

The occurrence of germ cell tumors (GCTs) in the vagina is uncommon in children, with yolk sac tumors being the most commonly identified histological subtype in young female infants.

Clinical Description:

A 7-month-old baby girl was presented with gradually progressive painless vaginal bleeding for 2 weeks. The infant was otherwise thriving well with no evidence of any local or systemic abnormality or constitutional symptoms.

Management and Outcome:

The child’s initial laboratory investigations were normal except for mild anemia. Further tests revealed elevated alpha-fetoprotein levels. Magnetic resonance imaging showed a mass in the vagina, which on cystovaginoscopic biopsy showed vaginal GCT. The patient was treated as per carboplatin (JM8), etoposide, and bleomycin (JEB) protocol. After the completion of the first cycle of chemotherapy, the infant responded well and was symptom-free.

Conclusion:

Vaginal bleeding in an otherwise healthy infant should raise suspicion of malignancy with GCT being a rare occurrence in this location. The present case highlights the success of the JEB protocol which is well tolerated by an infant.
Physical Activity in the Older Adults: A Review of the Benefits and Recommendations for Promoting Healthy Aging through Exercise
Authors: Indrakumar Jegarajah , Silva Shehan
Published: November 2024

This literature review examines the advantages of regular physical activity for older individuals, who often experience declines in physical and cognitive capabilities that impact their health and quality of life. Regular exercise has been demonstrated to counteract many age-related negative effects by improving cardiovascular health, including enhanced heart function, increased circulation, and reducing the risk of atherosclerosis and coronary artery disease while promoting longevity. In addition, resistance training is beneficial in preserving muscle mass and strength, which is crucial for maintaining independence and preventing falls. Furthermore, resistance training can improve bone density, preventing osteoporosis, and sarcopenia. Furthermore, physical activity supports brain health by promoting neurogenesis, preventing cerebral atrophy, and enhancing neuroplasticity, which can lead to improved cognition, memory, and executive function. Exercise can also alleviate the symptoms of depression and anxiety, significantly enhancing mental well-being. Virtual group-based exercise programs have been found to effectively reduce depressive symptoms and promote social engagement, combating loneliness and improving emotional well-being. The review emphasizes the extensive benefits of regular physical activity for older adults, including cardiovascular and musculoskeletal health improvements, cognitive function, and mental well-being. It recommends implementing tailored exercise programs and community-based initiatives and using technological tools to encourage and monitor physical activity among older individuals, which is vital for enhancing their quality of life.
Sex-related Differences in Insulin Resistance in the Geriatric Population
Authors: Kant Ravi , Jha Dipesh , Karna Gaurav , Routhu Balachandra , Dhar Minakshi
Published: November 2024

Background:

Diabetes mellitus significantly impacts long-term cardiovascular disease, increasing elderly mortality and morbidity. Half of elderly diabetics are asymptomatic, with vague symptoms. Insulin resistance (IR) and pancreatic beta-cell dysfunction are central to diabetes pathophysiology. Gender differences in IR and beta-cell function are increasingly recognized in diabetes research.

Methods:

In 18-month observational cross-sectional study focusing on elderly patients (60+) done at tertiary hospital in North India included 32 diabetic and 32 healthy controls. Fasting blood sample of eligible subjects were sent for hemogram, hemoglobin A1c (HBA1c), blood glucose, and insulin. IR and beta-cell function were calculated using the homeostasis model assessment (HOMA) model and analyzed using SPSS, with P < 0.05.

Results:

The mean age of participants was 67.77 years and the average duration of having diabetes was 5.11 years. Median HOMA IR was significantly higher in cases compared to controls (4.23 vs 0.89, P < 0.05), while HOMA β was comparable. HOMA IR decreased with longer diabetes duration, with a more rapid decline in female subjects compared to males. Subgroup analysis showed IR increased with age and was higher in females.

Conclusion:

Our research highlights gender-based differences in IR in the geriatric age group. Elderly women had higher IR compared to men. These findings are significant in understanding gender-specific metabolic differences and tailoring interventions. Further research with a larger sample size is warranted to corroborate these findings.

Clinical Implication:

This study addresses the gap in research on IR and beta-cell function in the elderly, particularly in India. This research can be compared with past studies on other age groups, aiding in the development of tailored diabetes treatments and improving therapeutic strategies for the elderly.

The accelerating pace of population aging in Asia poses significant challenges for health care and economies. As life expectancy increases and chronic diseases become more prevalent, understanding and addressing the healthcare needs of older adults is crucial. This review examines the key health issues affecting older adults in Asia, including nutritional status, mobility limitations, frailty, sarcopenia, mental, and cognitive health concerns. The authors conducted a mini-review of research on the health challenges faced by older adults in the region, drawing from a wide range of sources, including indexed and nonindexed journals and databases. The review highlights that aging in Asia is accompanied by a sharp rise in physical and mental health problems. While life expectancy in Asia has increased, many older adults experience declining physical and mental health, burdened by inadequate nutrition, frailty, and sarcopenia. Mental health issues, exacerbated by social isolation and limited access to services, are particularly prevalent in this population. The rapid pace of aging in Asia, coupled with the increased vulnerability of older adults and the lack of comprehensive national aging policies, highlight the region’s unpreparedness to address the challenges faced by older adults. This demands urgent actions. To ensure healthy aging, Asia must prioritize a comprehensive national policy that addresses physical and mental health, economic security, productive work, and social engagement. Investing early in the health of older adults, promoting healthy lifestyles, accessible and older adults’ friendly infrastructure, and integrated, holistic health care can reap long-term benefits, reducing healthcare burdens and improving quality of life.
Interobserver reliability of sonographic measurement of inferior vena cava and aorta parameters in fasting children in the perioperative period: A prospective observational study
Authors: Thaware Pooja , Choudhary Pooja , Ahmad Zainab , Jangid Surendra , Ahmad Reyaz , Kumar Amber , Waindeskar Vaishali
Published: November 2024

Background and Aims:

Point-of-care ultrasound conducted by anesthesiologists plays a crucial role in ensuring the safety of anesthesia. This study aims to evaluate the interobserver reliability of ultrasound measurements of the inferior vena cava (IVC) and aorta diameters in fasting pediatric patients undergoing spontaneous and controlled ventilation. Despite the prevalent use of indices for intravascular volume assessment, their accuracy varies depending on the observer’s expertise, particularly in pediatric cases. This research seeks to provide valuable insights into the interobserver reliability of ultrasound measurements in pediatric patients.

Material and Methods:

A single-center prospective observational study was conducted involving pediatric patients aged 1–12 years undergoing elective surgery. Ethical approval and written consent were obtained, with exclusions for major cardiovascular issues. Ultrasound measurements of IVC and aorta were performed by two observers during spontaneous and controlled ventilation in the subxiphoid transabdominal long-axis view. Reliability was assessed through statistical analyses, including the intraclass correlation coefficient and Bland-Altman analysis.

Results:

Mean values of IVC and aorta diameters were summarized for both observers during different ventilation modes. The intraclass correlation coefficient indicated excellent to good agreement between the observers for both spontaneous and controlled ventilation scenarios. Bland-Altman analysis revealed no fixed or proportional errors, confirming the reliability of the measurements.

Conclusions:

This study establishes the reliability of ultrasound measurements for assessing IVC and aorta in subxiphoid transabdominal long-axis view. The findings highlight the potential of this technique in pediatric anesthesia, even after brief training, providing valuable insights for clinical practice.
Comparison of hemodynamic responses to nasal intubation in cancer patients receiving opioid-free general anesthesia versus standard regimen
Authors: Rajan Sunil , Varghese Merin , Nair Anjali S. , Kumar Lakshmi
Published: November 2024

Background and Aims:

Nasotracheal intubation evokes greater hemodynamic responses than oral intubation. We compared the heart rate (HR) and mean arterial pressure (MAP) responses following nasal intubation during opioid-free anesthesia (OFA) using intravenous lignocaine versus standard regimen using morphine in cancer patients undergoing tumor resection.

Material and Methods:

This randomized, double-blinded study was conducted in 84 adults. Group A received lidocaine bolus 1.5 mg/kg over 10 min followed by infusion of 1 mg/kg/h. Group B received morphine 0.2mg/kg bolus over 10 min followed by infusion of 2mg/h. Protocols for induction and intubation were similar.

Results:

Mean HR and MAP at preinduction, immediately after induction, and at 1, 3, and 5 min after intubation were comparable in groups A and B. Intragroup comparison of preinduction HR with subsequent values in group A showed that the HR values at 1,3, and 5 min after intubation were significantly higher than the preinduction value. HR after induction was comparable. Intragroup analysis in group B showed that preinduction HR was comparable with HR after induction and at 3 and 5 min after intubation. HR at 1 min was significantly higher. Intragroup analysis in group A showed that the MAP values were significantly lower than the preinduction value after induction and at 1,3, and 5 min after intubation. In group B, MAP was significantly lower than the preinduction value after induction and at 3 and 5 min after intubation, with the value being comparable at 1 min.

Conclusion:

OFA with lignocaine bolus followed by infusion, as well as morphine did not attenuate the HR responses to nasal intubation in cancer patients. However, both techniques effectively blunted the MAP response.
Pairs in discrete lattice orbits with applications to Veech surfaces (with an appendix by Jon Chaika)

Let

\Lambda_{1}

,

\Lambda_{2}

be two discrete orbits under the linear action of a lattice

\Gamma<\mathrm{SL}_{2}(\mathbf{R})

on the Euclidean plane. We prove a Siegel–Veech-type integral formula for the averages

\sum_{{\bf x}\in\Lambda_1}\sum_{{\bf y}\in\Lambda_2}f({\bf x},{\bf y}),

from which we derive new results for the set

S_{M}

of holonomy vectors of saddle connections of a Veech surface

M

. This includes an effective count for generic Borel sets with respect to linear transformations, and upper bounds on the number of pairs in

S_{M}

with bounded determinant and on the number of pairs in

S_{M}

with bounded distance. This last estimate is used in the appendix to prove that for almost every

(\theta,\psi)\in S^{1}\times S^{1}

the translation flows

F_{\theta}^{t}

and

F_{\psi}^{t}

on any Veech surface

are disjoint.

Effect of three-week exercise program on muscle strength and joint mobility in patients with diabetic polyneuropathy: Randomized controlled trial
Authors: Novaković-Bursać Snježana , Talić Goran , Tomić Nataša , Škrbić Ranko , Soldatovic Ivan
Published: November 2024

BACKGROUND

Limited joint mobility is the proven risk factor for diabetic foot ulceration when present in the subtalar and first metatarsophalangeal joints. Evidence shows that a foot-related exercise program, combined with a health-promoting program, can improve the signs and symptoms of diabetic polyneuropathy, enhance gait, restore mobility in the foot and ankle joints, redistribute pressure while walking, and increase foot strength and function. As a result, these exercise programs can help mitigate the risk factors for diabetic foot ulceration.

AIM

To determine the effect of supervised stretching, strengthening, functional and walking exercises on joint mobility and muscle strength in patients with diabetic polyneuropathy.

METHODS

This was a randomized controlled trial conducted in a tertiary hospital. The study included 82 participants allocated into the intervention group (alpha-lipoic acid and exercise on 15 consecutive therapeutic days, n = 42) and control group (alpha lipoic acid only, n = 40). Muscle strength included dorsal and plantar flexors dynamometry and strength score, while range of motion included ankle, subtalar and first metatarsophalangeal joint goniometry.

RESULTS

Change of motion range was significantly higher in the intervention group compared to the control group regarding ankle joint on day 15 (9.9 ± 7.2 vs 0.1 ± 3.3; P = 0.006) and month 6 (2.8 ± 7.3 vs -0.9 ± 4.1; P < 0.001), subtalar joint on day 15 (7.5 ± 5.1 vs -0.25 ± 2.25; P < 0.001) and month 6 (3.9 ± 6.4 vs -0.13 ± 3.49; P < 0.001). Change in dorsal flexors was significantly higher in the intervention group compared to the control group on day 15 (2.62 ± 1.69 vs 0.10 ± 1.35; P < 0.001) and month 6 (0.66 ± 2.38 vs -0.75 ± 1.94; P = 0.004) as well as plantar flexors on day 15 (3.3 ± 1.6 vs 0.3 ± 1.5; P < 0.001) and month 6 (1.8 ± 2.2 vs -0.9 ± 2.1; P < 0.001). Muscle strength score change was significantly lower in the intervention group compared to the control group on day 15 (-1.45 ± 1.42 vs -0.03 ± 0.16; P < 0.001) and month 6 (-1.17 ± 1.53 vs 0.20 ± 0.56; P < 0.001).

CONCLUSION

Exercise in combination with alpha-lipoic acid can improve joint mobility, as well as strength of the foot and lower leg muscles in patients with diabetic polyneuropathy.
Can an Intramedullary Nail Be Used for Hip Fracture Prevention in a
Sideways Fall Scenario?

Published: November 2024

Fragility fracture of the hip is a global health concern with generally poor
outcomes. Clinical studies have shown prophylactic augmentation of the femur to
be a plausible intervention with success in some approaches; however, its use is
not yet widespread in the clinical community. We aimed to evaluate the efficacy
and clinical safety of prophylactic intramedullary nailing for hip fracture
prevention after a fall impact in six cadaveric pelvis–femurs. Post-fall
fracture status of the native specimens was determined in a virtual control
group built using a validated and peer-reviewed finite element method. A
commercially available intramedullary nailing system was prophylactically
implanted in all specimens. After augmentation, specimens were subjected to an
experimental sideways fall impact and inspected for fracture. Overall, fracture
status was unchanged or lowered in severity in the augmented group compared to
the native control group. No sign of femur fracture was found in the group
augmented by intramedullary nailing, but two augmented specimens exhibited
pelvis fractures after the impact. No safety concerns associated with
prophylactic nailing were found. These results suggest that prophylactic nailing
may reduce the potential for hip fracture in a sideways fall impact but would
not reduce the likelihood of pelvis fracture, and may shift femur fractures to
instead be pelvis fractures. This study provides a robust biomechanical
evaluation of prophylactic augmentation with a device already familiar to
orthopedic surgeons, broadening the options currently considered for the
prevention of hip fractures.
