Abstract
We report a cyclic variation of the O − C diagram with a semiamplitude of 0.0033 days and a period of 1.05 yr for the pulsating eclipsing binary HZ Dra. The cyclic variation can be explained by the light travel-time effect via the presence of a close-in third body orbiting around HZ Dra in an elliptical orbit with a maximum semimajor axis of 0.89 au. Based on the Wilson–Devinney code, the contribution of the third light to the total system is determined to be 29.0%, which is in agreement with the estimated value. Our light-curve modeling indicates an evolving hot and cool spot on the surface of the primary and secondary components, respectively. Their positions are roughly symmetrical to the inner Lagrangian point L1, which could be used to explain the variation in the O'Connell effect. Our frequency analysis detects one radial p-mode, seven nonradial p-modes, and one nonradial g-mode. In addition, a total of six multiplets are identified, spaced by the orbital frequency, which can be explained as a tidally split mode caused by the equilibrium tides of the close binary system with a circular orbit. These pulsating features suggest that the primary of HZ Dra is a δ Scuti star, pulsating in both p- and g-mode and influenced by tidal forces.
Absolute Dimensions of the Interferometric Binary HD 174881: A Test of Stellar Evolution Models for Evolved Stars

Abstract
We report high-resolution spectroscopic monitoring and long-baseline interferometric observations with the Palomar Testbed Interferometer (PTI) of the 215 day binary system HD 174881 (K1 II-III), composed of two giant stars. The system is spatially resolved with the PTI, as well as in archival measurements with the CHARA Array. Our analysis of these observations, along with an analysis of the spectral energy distribution, have allowed us to infer accurate values for the absolute masses (

), radii (34.0 ± 1.3 and 22.7 ± 1.8 R
☉), effective temperatures (4620 ± 100 and 4880 ± 150 K), and bolometric luminosities of both components, as well as other properties including the orbital parallax (distance). These provide valuable tests of stellar evolution models for evolved stars, which are still relatively uncommon compared to the situation for main-sequence stars. We find generally good agreement of all of these properties of HD 174881 with two sets of recent models (MIST and PARSEC) at compositions near solar, for ages of 255–273 Myr. We also find evidence of an infrared excess, based largely on the flux measurements from IRAS at 60 and 100 μm.
Neutrino Detection Rates from Lepto-hadronic Model Simulations of Bright Blazar Flares
Authors: Robinson Joshua , Böttcher Markus 
Published: December 2024

Abstract
There is mounting evidence that blazars are the sources of part of the very-high-energy astrophysical neutrino flux detected by IceCube. In particular, there have been several spatial and temporal coincidences of individual IceCube neutrino events with flaring blazars, the most prominent of them being IceCube-170922A, coincident with a multiwavelength flare of TXS 0506+056. Motivated by this, we used the time-dependent lepto-hadronic code OneHaLe to model the spectral energy distributions and light curves of a sample of bright γ-ray flares of blazars detected by Fermi-Large Area Telescope, for which Kreter et al. provided calorimetric estimates of the expected neutrino detection rates. Flares were modeled with temporal changes of the proton injection spectra. Our analysis shows that the calorimetric approach overestimates the increase in neutrino production by a factor of typically ∼10 if the γ-ray emission is dominated by proton-synchrotron radiation.
Astrophysical Properties of the Sirius Binary System Modeled with MESA
Authors: Khan Momin Y. , Castanheira Barbara G. 
Published: December 2024

Abstract
Sirius is the brightest star in the night sky and, despite its proximity, this binary system still imposes intriguing questions about its current characteristics and past evolution. H. E. Bond et al. published decades of astronometric measurements of the Sirius system, determining the dynamical masses for Sirius A and B, and the orbital period. We have used these determinations, combined with photometric determinations for luminosity and spectroscopic determinations of effective temperature (T
eff) and metallicity, to model the evolution of the Sirius system using Modules for Experiments in Stellar Astrophysics. We have constructed a model grid calculated especially for this system and were able to obtain, for Sirius B, a progenitor mass of 6.0 ± 0.6 M
⊙, yielding a white dwarf mass of 1.015 ± 0.189 M
⊙. Our best determination for the age of the system is 203.6 ± 45 Myr with a metallicity of 0.0124. We have compared our best-fit models with the ones computed using TYCHO, YREC, and PARSEC, establishing external uncertainties. Our results are consistent with the observations and support a noninteracting past.

Published: December 2024

Purpose
To assess the impact of a home care intervention on the family support needs of nursing home residents through a group clinical trial and blinded outcome assessment.

Method

A cluster randomized trial was conducted at two nursing homes in Zhengzhou. Each nursing home was randomized to either the intervention or control group. Eighty-two residents were enrolled in the study. Intervention group participants (
n
= 41) received a family support intervention, and those in the control group (
n
= 41) received the institution's standard daily care routine. The Questionnaire of Family Support Needs; Perceived Social Support Scale; and Family Adaptation, Partnership, Growth, Affection, Resolve Index were used to assess post-intervention outcomes.

Results

There were no significant differences between groups regarding baseline data. There were statistically significant (
p
< 0.05) within-subject, between-subject, and interaction effects for both groups regarding family support needs, perceived social support, and family functioning.

Conclusion

Findings contribute to strengthening the care of residents in nursing homes, indicating the importance of family support, which can positively influence perceived social support and family function. The long-term efficacy of the intervention should be further verified. [

Définir la noblesse
Authors: Pollet Camille 
Published: November 2024

Dans les sociétés européennes du xviie siècle, sauf exceptions, les gens naissaient et demeuraient inégaux en droits. La noblesse représentait un statut largement convoité, mais sa définition faisait l’objet de controverses incessantes, exprimées par des livres publiés par centaines : les traités nobiliaires. Qui était noble et qui ne l’était pas ? Comment justifier cette distinction fondamentale ? Comment définir la noblesse des femmes ? Pouvait-on devenir noble ? Que signifiait la rhétorique du « sang » et de l’« occulte semence » ? C’est sur ces problèmes sociaux que s’écharpaient les théoriciens dans l’Espagne des derniers Habsbourg, dans l’Angleterre des Stuarts et de la guerre civile, ainsi que dans la France d’Henri IV, de Louis XIII et de Louis XIV.Ce livre met en lumière les auteurs, les traducteurs et les libraires impliqués dans la production des traités nobiliaires, ainsi que leurs lecteurs. Il propose un regard comparatif sur les théoriciens et les traités anglais, français et espagnols. En analysant les interactions entre média et société, et en envisageant l’écriture et la publication comme des actions, cette enquête interroge l’intensité, la permanence et les enjeux de ces luttes de définition de l’ordre social.
Écriture et histoire : Derrida lecteur de L’origine de la géométrie
Authors: Terzi Roberto 
Published: November 2024

Dans cet article nous examinons la lecture que Derrida donne de l’origine de la géométrie de Husserl dans son Introduction de 1962, en nous concentrant notamment sur le thème de l’écriture dans son lien avec l’histoire. Après avoir rappelé son contexte, nous nous arrêtons, dans un premier moment, sur l’analyse que Derrida fait de l’écriture dans la section VII de l’Introduction et sur ses conséquences philosophiques plus générales, en tenant déjà compte du parcours suivant de Derrida. Nous opérons ensuite une confrontation entre l’analyse derridienne et la façon dont la question de l’écriture intervient dans les Notes de cours sur l’origine de la géométrie de Merleau-Ponty, pour montrer la spécificité des deux approches et leurs implications. Nous nous tournons enfin vers la question de l’« écriture générale » telle qu’elle est formulée dans les textes ultérieurs de Derrida, pour essayer de mettre en lumière, dans une interprétation plus libre, de quelle façon on peut la relier à la problématique originairement phénoménologique de la Stiftung.

Authors: Dantile Nokuzola D. , Mshunqane Nombeko , Van Staden Cornelius W. 
Published: November 2024

Background: Complaints of ethical and professional misconduct are lodged and processed by the Health Professions Council of South Africa (HPCSA) in accordance with their legal mandate.Objectives: This study describes the nature and frequency of transgressions by physiotherapists as concluded by the HPCSA for the period from 2010 to 2020.Method: A total sampling method was used to extract all records of transgressions lodged against physiotherapists between 2010 and 2020. In a quantitative retrospective records review design, data were captured with the objective to report these descriptively. Ethics approval was granted by the Faculty of Health Sciences Research Ethics Committee of the University of Pretoria and permission to use the records was granted by HPCSA.Results: Twenty-one transgressions by physiotherapists during the study period were recorded at the HPCSA. Most transgressions were charging for services not rendered (n = 20 times), invoices drafted inaccurately (n = 17) and false claims submitted to the medical aid schemes (n = 15). Other transgressions included failure to obtain informed consent and patient identity prior to treatment, charging for an unkept appointment, overservicing, misleading advertisements, love relationship with a patient and treating an animal in the same practice as humans.Conclusion: The transgressions were unprofessional in nature with the most frequently reported being false claims and accounts submitted to the medical aid by physiotherapists for services not rendered.Clinical Implications: The knowledge of transgressions will influence decision making and restrain infringement to enhance sound ethical practice.

Authors: Ghezelbash Behrooz , Deyhim Mohammadreza , Azarkeivan Azita , Pourfathollah Ali Akbar , Eskandari Nahid 
Published: November 2024

Background:
It is essential to maintain the quality of the stored blood, because various factors affect the stored red blood cells (RBCs) over time, some red blood cell storage lesions (RCSL) develop during storage, and it could reduce the function of the RBCs. The present study aimed to evaluate the effects of glutathione monoethyl ester on different biochemical changes, oxidant, and antioxidant levels in the leukoreduced RBCs (LR-RBCs) during storage.

Materials and Methods:
About 10 units of LR-RBC were collected, processed and stored according to the standard operating procedures (SOPs) of the Iranian Blood Transfusion Organization. Each unit divided into 2 equal parts; LR-RBC treated with glutathione monoethyl ester and a control group. Exposure of phosphatidylserine (PS), reactive oxygen species (ROS) and microvesicle derived from the RBCs (RBC-MVs), were measured by the flow cytometry method. ELISA was used to measure the level of glutathione, and 2, 3-diphosphoglycerate (2,3-DPG). Glucose-6-phosphate dehydrogenase (G6PD) enzyme activity was measured with a chemistry autoanalyzer.

Results:
The levels of glutathione reduced the initial value in the treated group (80%), and the control group (60%), respectively. Exposure of surface PS, ROS and RBC-MVs increased significantly during storage time for consecutive weeks to the amount of GSH. The levels of 2,3-DPG decreased with increasing storage time.

Conclusions:
Overall, The study suggest that glutathione monoethyl ester is effective to reduce the oxidative stress and the quality of RBCs can be improved.

Authors: Akbari Aghdam Hossein , Shahrokh Seyedeh Ghazal , Ahmadi Omid , Rostami Koushan , Najafi Mohammad M. , Sadeghian Amirhossein , Hosseini Zahra , Anaraki Kasra Talebi 
Published: November 2024

Background:
Anterior cruciate ligament (ACL) injury has an incidence of 0.05–0.08 per thousand. An inappropriate treatment plan could lead to articular cartilage damage and early knee osteoarthritis. Some surgical reconstruction techniques use different graft types; all of them try to restore the patient’s preinjury activity levels. The current study aims to evaluate the efficacy of ACL reconstruction (ACLR) using an autologous hamstring tendon.

Materials and Methods:
This is a retrospective one-center cohort study performed on consecutive patients with an ACL injury who underwent ACLR using semitendinosus and gracilis autograft. The postsurgical activity and fear were measured using Marx scale and Tampa scale of kinesophobia, respectively, during a follow-up of 18 months.

Results:
From a total of 76 patients included in our study, 40.8% were female. The mean age of the participants was 26.25-year-old. Five patients from those with kinesophobia (12.5%) and 34 patients from those with no-kinesophobia (94%) returned to the preinjury activity level (P value < 0.001). Marx scale six months after the surgery was significantly lower than the score before the surgery, but as expected, it improved during the 18-month follow-up.

Conclusion:
The current study showed that kinesophobia reduces the rate of return to preinjury levels. Maybe, overcoming this fear will help these patients to reach better results. However, we suggest implementing further trials in larger sample sizes before reaching a solid conclusion.

Authors: Balachandran Saravanan , Rajkumar Murugesan , Omprakash Shanmuganandam , Rajkumar Sharath , Tharani Megala , Arumugam Sarathkumar , Prakash Junia 
Published: November 2024

Abstract
Postthrombotic syndrome (PTS) is a form of chronic venous insufficiency that occurs secondary to deep vein thrombosis in up to 50% of all patients. PTS is largely attributed to the incomplete lysis of the intraluminal thrombus resulting in the formation of intimal synechiae. Although a wide range of treatment practices are available, PTS continues to adversely impact the patients’ quality of life, consequently increasing the need for optimizing existing methods of management. With regard to percutaneous transluminal venoplasty, complexities are encountered in advancing balloon dilatation catheters through the lesions due to the presence of obstructing endovenous synechiae. In this case report, a venoplasty technique is described for improving iliac vein negotiation through intimal synechiae in a young patient suffering from PTS with complete iliac vein occlusion wherein considerable difficulty was encountered during venoplasty.

Published: November 2024

ABSTRACT
Hereditary vitamin D-resistant rickets type 2A (HVDRR2A; OMIM 277440) is caused by heterogeneous mutations in the vitamin D receptor (VDR) gene and is transmitted as an autosomal recessive trait. In this study, we report the clinical profile and management of two Indian cases of HVDRR2A, both presenting with alopecia and bony deformities. Blood investigations revealed hypocalcemia, elevated intact parathyroid hormone (iPTH), and high levels of 1,25-dihydroxyvitamin D [1,25(OH)2D3]. Molecular studies identified a novel homozygous c.1090 C > T (p.Gln364Ter) pathogenic variant in the VDR gene, resulting in a stop codon and premature protein truncation at the 364th amino acid position. Both patients were managed with intravenous calcium, high oral calcitriol, and cholecalciferol sachets.
A curative etiology of severe hirsutism with virilization – Sertoli Leydig cell ovarian tumor

Published: November 2024

ABSTRACT
Hirsutism is one of the earliest manifestations of virilization. The most common cause of hirsutism in a reproductive-age woman is polycystic ovarian disease. Androgen-producing tumors of the ovary or adrenals will cause severe hirsutism and virilization. The biochemical measurements of total testosterone and dihydro-epi androstenedione sulfate are useful to localize the source of hyperandrogenism. The medical management of severe hirsutism with virilism is difficult in the idiopathic variety. However, the prognosis is excellent for androgen-secreting benign ovarian and adrenal tumors, and surgical resection is often the treatment option in most of these cases. In this study, we report a case of a 26-year-old female presenting with secondary amenorrhea with clinical features of androgen excess with virilization. The biochemical and imaging characteristics are suggestive of an androgen-secreting ovarian tumor. Following right oophorectomy, the histopathology and immunohistochemistry confirmed benign Sertoli Leydig cell tumor, and clinical and biochemical features normalized after 3 months of the curative surgical procedure.
Type 1 Marine-Lenhart syndrome: An uncommon cause of thyrotoxicosis
Authors: Jha Vivek , Das Liza , Baruah Mintu Mani , Sood Ashwani , Bhadada Sanjay Kumar 
Published: November 2024

ABSTRACT
Marine-Lenhart syndrome (MLS) refers to the simultaneous occurrence of Graves’ disease (GD) and functional thyroid nodules. This report discusses a case of Type 1 MLS characterized by hyperthyroidism, the detection of thyroid-stimulating hormone receptor antibodies, and a noticeable right thyroid nodule in a middle-aged female. A thyroid scan displayed heightened tracer uptake in this nodule and uniformly elevated uptake throughout the rest of the thyroid gland. The patient received treatment with anti-thyroid medications, followed by radioiodine ablation, and is currently on levothyroxine replacement therapy. This case illustrates the importance of considering MLS in patients with both thyroid nodules and GD, especially when they exhibit an inadequate response to standard anti-thyroid drugs.
Cutting balloon: Device, current indication, and usage
Authors: Agarwal Praveer , Mahajan Swati 
Published: November 2024

Abstract
The management of coronary artery disease has been revolutionized by percutaneous coronary interventions (PCI). With the advancements and availability of multiple tools in the repertoire, an interventional cardiologist tends to attempt complex of the lesions. The success of PCI, however, has been limited by restenosis, and acute ischemic events, hence prior lesion preparation and plaque modification, before stenting, becomes very important. Of the various tools available, cutting balloon (CB), developed by Barth, is increasingly being used nowadays. It is a special balloon with 3 to 4 atherotomes (blades), which tend to create longitudinal incisions in the plaque, in a controlled manner. CB finds its use in coronary as well as peripheral vascular system. It is important to understand the device, how to use it and more importantly where to use it. In this article we summarize the uses, indications and available experience with CB.
