Relationship between Tpeak-Tend (TPE), TPE/QT ratio and TPE dispersion in patients with subclinical hyperthyroidism
Authors: Bilen Mehmet Nail , Gözel Nevzat 
Published: March 2024

Aims: Subclinical hyperthyroidism has been associated with an increased risk of cardiovascular events, including atrial fibrillation, heart failure, and cardiovascular mortality. Tpeak - Tend interval (TPE), TPE/QT ratio, and TPE dispersion have been suggested as potential electrocardiographic markers of ventricular repolarization abnormalities, which may be associated with an increased risk of arrhythmias and sudden cardiac death. However, the relationship between subclinical hyperthyroidism and these parameters remains unclear.
Methods: We conducted a cross-sectional study to investigate the relationship between subclinical hyperthyroidism and TPE, TPE/QT ratio, and TPE dispersion. A total of 106 patients were included in the study, with 42 patients diagnosed with subclinical hyperthyroidism group and 64 control group. Conventional echocardiographic and electrocardiographic parameters were measured and compared between the two groups.
Results: There are no significant differences in age (p=0.707) or gender (p=0.552) between the two groups. Patients in the subclinical hyperthyroidism group had significantly higher TPE, TPE/QT ratio, and TPE dispersion compared to the control group (p

Abstract
A classical local thermodynamic equilibrium analysis, based on high-resolution spectroscopic data, is performed for a sample of three potential barium dwarf candidates and one star already recognized as such. We derived their atmospheric parameters, estimated their masses and luminosities, and determined chemical abundances for a set of 21 elements, including CNO. Some elemental abundances are derived for the first time in HD 15096, HD 37792, and HD 141804. The program stars are dwarfs/subgiants with metallicities typical of disk stars, exhibiting moderate carbon enhancements, with [C/Fe] ratios ranging from +0.29 to +0.66 dex, and high levels of slow neutron-capture (s-process) elements, with [s/Fe] ≳ + 1.0 dex. As spectroscopic binaries, their peculiarities are attributable to mass transfer events. The observed neutron-capture patterns of were individually compared with two sets of s-process nucleosynthesis models (Monash and fruity), yielding dilution factors and masses estimates for the former polluting asymptotic giant branch stars. Low-mass (≲3.0 M
⊙) models successfully reproduce the observations. In addition, we estimated mean neutron exposures on the order of 0.6–0.7 mb−1 for the s-processed material observed in their envelopes. Applying an empirical initial-final mass relation, we constraint in ∼0.7 M
⊙ the mass of their dim white dwarf companions. Moreover, our kinematic study revealed that the program stars are members of the thin disk, with probabilities greater than 70%. Hence, we identified HD 15096 and HD 37792 as new barium dwarfs and confirmed that HD 141804 is a barium dwarf. Thus, the number of barium dwarfs identified in the literature from high-resolution spectroscopy increases to 71 objects.

Published: March 2024

Abstract
Until now, how the magnetic fields in M/X-class flaring active regions (ARs) differ from C-class flaring ARs remains unclear. Here, we calculate the key magnetic field parameters within the area of high photospheric free energy density (HED region) for 323 ARs (217 C- and 106 M/X-flaring ARs), including total photospheric free magnetic energy density E
free, total unsigned magnetic flux ΦHED, mean unsigned current helicity h

c
, length of the polarity inversion lines L
PIL with a steep horizontal magnetic gradient, etc., and compare these with flare/coronal mass ejection (CME) properties. We first show the quantitative relations among the flare intensity, the eruptive character, and ΦHED. We reveal that ΦHED is a measure for the GOES flux upper limit of the flares in a given region. For a given ΦHED, there exists the lower limit of F
SXR for eruptive flares. This means that only the relatively strong flares with the large fraction of energy release compared to the total free energy are likely to generate a CME. We also find that the combinations of E
free–L
PIL and E
free–h

c
present a good ability to distinguish between C-class and M/X-class flaring ARs. Using determined critical values of E
free and L
PIL, one predicts correctly 93 out of 106 M/X-class flaring ARs and 159 out of 217 C-class flaring ARs. The large L
PIL or h

c
for M/X-class flaring ARs probably implies the presence of a compact current with twisted magnetic fields winding about it.
How Long-lived Grains Dominate the Shape of the Zodiacal Cloud
Authors: Pokorný Petr , Moorhead Althea V. , Kuchner Marc J. , Szalay Jamey R. , Malaspina David M. 
Published: March 2024

Abstract
Grain–grain collisions shape the three-dimensional size and velocity distribution of the inner Zodiacal Cloud and the impact rates of dust on inner planets, yet they remain the least understood sink of zodiacal dust grains. For the first time, we combine the collisional grooming method combined with a dynamical meteoroid model of Jupiter-family comets (JFCs) that covers 4 orders of magnitude in particle diameter to investigate the consequences of grain–grain collisions in the inner Zodiacal Cloud. We compare this model to a suite of observational constraints from meteor radars, the Infrared Astronomical Satellite, mass fluxes at Earth, and inner solar probes, and use it to derive the population and collisional strength parameters for the JFC dust cloud. We derive a critical specific energy of

J kg−1 for particles from JFC particles, making them 2–3 orders of magnitude more resistant to collisions than previously assumed. We find that the differential power-law size index −4.2 ± 0.1 for particles generated by JFCs provides a good match to observed data. Our model provides a good match to the mass-production rates derived from the Parker Solar Probe observations and their scaling with the heliocentric distance. The higher resistance to collisions of dust particles might have strong implications to models of collisions in solar and exosolar dust clouds. The migration via Poynting–Robertson drag might be more important for denser clouds, the mass-production rates of astrophysical debris disks might be overestimated, and the mass of the source populations might be underestimated. Our models and code are freely available online.
Demjanjuk et après
Authors: Douglas Lawrence , Théofilakis Fabien 
Published: March 2024

La condamnation de John (Ivan) Demjanjuk par un tribunal de Munich en 2011 a marqué un tournant juridique important, bien que tardif, dans le traitement des atrocités nazies par le système judiciaire allemand. Elle a également ouvert la voie à la condamnation en 2015 d’Oskar Gröning, ancien garde SS à Auschwitz, par un tribunal de Lüneburg, puis celle de Reinhold Hanning par un tribunal de Detmold en 2016, ainsi que celle de Bruno Dey, ancienne sentinelle au Stutthof par un tribunal de Hambourg en 2020. L’article soutient la thèse selon laquelle le cas de Gröning ne s’est pas contenté de suivre le précédent établi par le tribunal de Munich ; il s’est plutôt écarté de façon spectaculaire de la logique qui prévalait dans la décision Demjanjuk, et ce d’une manière qui souligne les ambiguïtés persistantes quant à la nature de la responsabilité pénale en droit allemand pour les crimes des camps de concentration.
Quentin Skinner and the Autonomy of Ideas
Authors: Phillips Owen 
Published: March 2024

Cet article explore deux aspects essentiels et inséparables de la méthodologie de Quentin Skinner : son contextualisme et son holisme. Ces postulats ont au moins deux conséquences inattendues. La première est que le sens (le contenu d’une proposition) est contextuel, continuellement redéfini et pas nécessairement restreint. La seconde conséquence est, malgré les apparences, qu’une défense de l’autonomie des idées n’est pas incompatible avec les fondements de l’histoire intellectuelle. Cela permet de mettre en lumière un sujet crucial pour tout historien des idées : le développement diachronique et collectif des théories (c’est-à-dire la manière dont la réception d’un auteur contribue à déterminer ce que cet auteur défend). Cet éclairage permet de mieux comprendre pourquoi la reformulation d’une théorie ne pose pas de problème d’anachronisme.
Accounting for Intellectual Traditions in the History of Ideas
Authors: Giuseppe Palmer Daniele 
Published: March 2024

Cet article examine la manière dont les traditions intellectuelles ont été étudiées dans le cadre de l’histoire des idées, avec un accent particulier sur le travail de David Armitage. Si l’effort de retracer les idées à travers le temps est considéré comme un objectif analytique valable, la tendance à oublier la contingence inhérente à la pensée est critiquée. Le travail d’Armitage, dont se sont inspirés de nombreux chercheurs, repose sur un appel implicite aux structures de la pensée : les idées existent au-delà de la spécificité des esprits humains individuels. En réponse à l’histoire intellectuelle à long terme d’Armitage, cet article propose une méthode pour rendre compte des idées de manière diachronique sans renoncer à la stricte historicité de la méthode contextualiste. Pour ce faire, la pragmatique en tant que théorie générale de la signification est réaffirmée. De plus, l’article, en se penchant sur les études à long terme des idées, renforce la distinction entre la théorie politique et la recherche historique : alors que la première peut supposer, et souvent requiert, l’abstraction, la seconde y est intrinsèquement opposée.
Masculinities in Transition: Ciaran Carson, Alan Gillis and Padraig Regan in and out of Belfast
Authors: Theinová Daniela 
Published: March 2024

In “Turn Again”, his poetic “guide” to Belfast and its poetry, Ciaran Carson writes that “Today’s plan is already yesterday’s – the streets that were there are gone”. This essay explores how Carson follows his own advice and how his poetics of rambling have inspired two younger Belfast poets, Alan Gillis and Padraig Regan. All three foreground walking and movement through urban spaces as a powerful literary trope and an effective tool of social criticism. Their anachronistically male or emphatically other personae guide us to the parallel city found between “observation and invention” (Gillis), which corresponds with Walter Benjamin’s notion of the Parisian arcades as a place in which layers of time, space and consciousness coalesce. Tracing trajectories of mutual influencing between three generations of Northern Irish poets can help us appreciate the collapsed hierarchy of time in a society that always threatens to relapse into its earlier confusion.
Changing trends in the management of posttransplant ureteric stricture
Authors: Choudhury Sunirmal , Malakar Subhajit , Pal Dilip Kumar 
Published: March 2024

Abstract

Introduction:
Chronic kidney disease (CKD) is a common disease now. Diabetes and hypertension are the main cause. Renal transplant is a gold standard treatment. Posttransplant stricture is also common, and changing trends in management are emerging.

Materials and Methods:
It is a retrospective observational study in a tertiary care hospital in East India. The study duration was from January 2019 to December 2021. In total, 140 patients were studied, including both live and cadaveric transplants. A patient who developed posttransplant hydronephrosis or presented with acute kidney injury was evaluated with ultrasonography, intravenous urography, contrast-enhanced computerized tomography, and magnetic resonance imaging. Management was done with double J (DJ) stenting, percutaneous nephrostomy (PCN) insertion, or surgical intervention.

Results and Analysis:
Twelve (8.6%) patients out of 140 developed posttransplant ureteric stricture. Five (41.7%) out of 12 patients were managed with long dura DJ stenting, and five (41.7%) were managed with PCN insertion and serial follow-up. Only two (16.7%) required ureteric reimplantation.

Discussion:
Posttransplant ureteric stricture is a common complication following renal transplantation. Common causes are increased cold ischemia time, ureteral edema, clots, tumors, calculi, lymphocele, abscess, and hematoma. Other causes include kinking of the ureter and previously unrecognized pelviureteric junction obstruction. In the literature, the incidence of posttransplant ureteric stricture ranges from 2% to 10% in one study; and in another study, it is 1% to 9%. In our study, it is 8.6%.

Conclusion:
Diagnosis of the posttransplant ureteric stricture should be prompt, and management should be given as early as possible for better graft survival.
Can quantitative monitoring of B cells evaluate the efficacy of Rituximab in primary CNS demyelinating disorders?

Published: March 2024

Abstract

Introduction:
Rituximab (RTX), initially approved for various blood cancers, is additionally used for the management of primary central nervous system (CNS) demyelinating disorders. This study aimed to quantify the % of B cells following RTX therapy in patients with primary CNS demyelinating disorders, so as to establish a correlation, if any, between the degree of B-cell depletion and clinical response(s).

Materials and Methods:
A prospective, observational study was conducted from February 2020 to August 2021 in 15 adults diagnosed with primary CNS demyelinating disorders. The % of B cells was quantified in terms of CD20 by flow cytometry, and clinical evaluation was by Expanded Disability Status Scale (EDSS) scores. Following the first dose of RTX, the %CD20 counts were measured 2 and 24 weeks later; subsequently, depending on the %CD20, RTX was administered. Accordingly, patients were divided into Group 1 (n = 7, %CD20 ≥ 1.5) and Group 2 (n = 8, %CD20 < 1.5) and followed up on the basis of CD counts till the completion of the study or until they were lost to follow-up. Safety was evaluated by recording of treatment-emergent adverse drug reactions (ADR).

Results:
In patients with CNS demyelinating disorders (n = 15), their median (interquartile range [IQR]) %CD20 and EDSS at baseline was 9.8 (5.6–18.8)% and 8.0 (7.5–8.0)%, respectively. In Group 1 (n = 7, %CD20 ≥ 1.5), there was a gradual decrease of %CD20 and EDSS, whereas in Group 2 (n = 8, %CD20 < 1.5), despite withholding RTX, patients remained asymptomatic, and their %CD20 remained <1.5 and EDSS showed a gradual decrease. 87% of patients experienced at least one ADR, the median (IQR) of ADRs per patient was 3 (0–3), and all 31 ADRs were infusion-related, with 100% recovery.

Conclusion:
RTX was relatively safe to use in these disorders, and monitoring its efficacy was adequately achieved using EDSS, with no additional benefits accrued by measuring %CD20 counts.
Participation, Learning and Environmental Justice: A Case Study of Protected Area Planning and Management in the Kullu District of Himachal Pradesh, India

Published: March 2024

Abstract
Achieving environmental justice in protected area (PA) planning and management has been historically problematic. Herein, potential connections between learning outcomes acquired through PAs and advancements in environmental justice are examined and assessed through a case study of PAs in the Kullu District of Himachal Pradesh, India. Specifically, our study aimed to identify learning outcomes that contributed to positive changes in distributive, procedural, recognitional and restorative justice for local people managing or residing near PAs. As throughout the Himalayas, the land use rights, both customary or recognised by law, of local inhabitants in the Kullu District have been altered and eroded through the establishment of PAs, which has resulted in poor environmental justice outcomes. Interviews were conducted with local people living near PAs, forest officers working in PAs, relevant government officials, academics, and NGO representatives. The results indicate that non-formal and informal learning has produced positive cognitive and relational changes in local inhabitants as well as forest officers, which has led to modification of policies, positive environmental change, and enhanced aspects of environmental justice. Though positive changes emerged, the study also identified a need for increased learning opportunities, particularly for inhabitants of more remote areas.

Authors: Gurbuz Ezgi , Ersoz Mehmet Meric , Arik Ozlem , Hatipoglu Hasan , Gungor Mujgan 
Published: March 2024

Aims:
Preoperative evaluation of maxillary sinus anatomy is crucial to minimize procedural complications. The aim of this study was to assess the anatomical structures associated with sinus augmentation and investigate the correlation between these structures.

Materials and Methods:
This retrospective study included cone-beam computed tomography scans of patients referred for the reconstruction of the posterior maxilla with dental implants. The intraosseous anastomosis (PIA) and septa were evaluated on the images. Lateral wall thickness (LWT), the diameter of the PIA (DIA), the vertical distance of the PIA to the sinus floor (DSF), and sinus floor angle (SFA) were also measured.

Results:
A total of 250 sinuses were examined. PIA was detected in 46.8% of the sinuses. The mean SFA value was 77.11° ±11.11° (range 48.25°–112.33°). The LWT ranged from 0.63 to 10.23 mm with a mean value of 1.35 ± 0.79 mm. Of 250 sinuses, 82 (32.8%) showed septa. A strong negative correlation was found between SFA and PIA detection (r = 0.98, P = 0.008), SFA and DSF (r = 0.99, P = 0.000), and SFA and septa (r = 0.98, P = 0.000). LWT showed a positive correlation with DIA (r = 0.72, P = 0.082), although not statistically significant.

Conclusions:
The relationships highlight the combined effect of the structures on membrane perforation. As this makes the lateral window approach more problematic, the surgeon may seek minimally invasive approaches. Moreover, the strong correlation of SFA-PIA-DSF may significantly affect graft vascularization and needs to be evaluated with clinical studies.
Lateralization of the Fine Motor Skills in Right - and Left-handed Men and Women
Authors: Mentese Beste , Kutlu Necip 
Published: March 2024

Introduction:
Motor performance is an important feature that can be measured to observe the development of the central and peripheral nervous system. Fine motor skill assessed by Morische-Leistungs-Serie (MLS) was studied in normal male and female right-handers and left-handers considering familial sinistrality and writing hand. Evaluations were conducted by measuring fine motor performance through the use of a modern computerized model.

Materials and Methods:
Hand preference was assessed by the Edinburgh Handedness Inventory Geschwind score (GS). Fine motor skills were measured by the MLS in the computerized Vienna Test System.

Results:
Left-handed volunteers had a significantly higher fine motor skills in both dominant and nondominant hands compared to right-handed volunteers.

Conclusions:
These results suggest that the contributions of the right and left cerebral hemispheres to the motor output of the brain depend on sex and more importantly, hand preference. It was determined that left handed subjects were more skillfull than right-handed subjects when dominant hands or weak hands were compared.

Authors: Roy Kheyali , Prakash Shaurya , Shetty Kannappa V. , Bamney Urmila , Singh Balkar 
Published: March 2024

AbstractIntroduction:Aging is the process of becoming older. Earlier old age homes were known by the name of Alms-houses. In recent time’s individualism, independence, and achieved position in the family have become a part of family culture in India. Sometimes, the separation is generated by the old themselves when they feel self-sufficient and desire independence. The practice of institutionalizing the elderly population is a broad-spreading concept in the modern world, and the number of old age homes is increasing at an alarming rate.Materials and Methods:The study explores the life experiences of the elderly living in a paid old age home. Samples were selected from an old age home with a population above the age of 65 years and institutionalized for at least 1 year. Case studies helped to fulfil the study objectives, and a semi-structured interview guide was also used.Results and Conclusion:The study found social, family, and personal issues among the elderly; some also have psycho-social issues and need specialized care at the primary, secondary, and tertiary levels.
Assessment of Oral Health Status and Factors Associated with Oral Health-related Quality of Life among Geriatric Population in Rural South India – A Community-based Cross-sectional Study
Authors: Vaddi Jeevan Kranthi , Jesija J. S. , Prasad John Davis , Kattula Deepthi , Paul G. Jackwin Sam , Prasad Jasmin Helan 
Published: March 2024

Abstract

Introduction:
In recent times, there is an increase in life expectancy leading to demographic transition toward aging population in both developed and developing countries. Oral health represents a major concern for general health; hence, the oral health of older people is increasingly important. One particularly meaningful factor is the number of teeth which provide information about the functionality of the masticatory system, an esthetic smile as well as an esthetic profile. Losing teeth can be psychologically traumatic, socially damaging, and functionally limiting, thereby affecting the quality of life (QoL).

Aim:
The aim of this study was to assess the oral health status and factors associated with poor oral health-related QoL in geriatric population (aged >60 years) in rural South India.

Materials and Methods:
A community-based cross-sectional study was conducted among 437 elderly in Kaniyambadi block of Vellore district. Sociodemographic details were collected directly by face-to-face interview, and the elderly were subjected to oral examination for oral health status. Oral health-related quality of life (OHrQoL) was measured using the Geriatric Oral Health Assessment Index (GOHAI). Factors associated with poor OHrQoL were analyzed using multiple logistic regression.

Results:
The study population comprised 31.1% (n = 136) of males and 68.9% (n = 301) of females, with a mean age of 68 (standard deviation – 6.9) years. On oral examination, the prevalence of dental caries and any type of edentulism was 51.5% (n = 225) and 82.4% (n = 360), respectively. The prevalence of complete edentulism was 10.1% (n = 44). By assessing oral health-related quality of life using the revised GOHAI tool, 30 (6.9%) had high scores between 34 and 36, 166 (38%) had scores between 31 and 33, and 241 (55.1%) had low scores (≤30). In the multivariate analysis, age >70 years (odds ratio [OR] =1.92, 95% confidence interval [CI] = 1.2–3.06, P = 0.006), male gender (OR = 1.78, 95% CI = 1.05–3.3, P = 0.033), and edentulism/severe tooth loss (OR = 8.64, 95% CI = 3.19–23.87, P < 0.001) had significantly higher odds for poor OHrQoL. Edentulism/severe tooth loss was also significantly associated with undernutrition (OR = 12.5, 95% CI = 6.56–23.81, P < 0.001).

Conclusion:
The burden of dental caries and edentulism in rural South India was high. The prevalence of edentulism had a significant impact on the OHrQoL. This study highlights the need for researchers to understand the importance of edentulism and its impact on overall health of the elderly, thereby focusing on health programs inclusive of oral health promotion and prevention.
