Monotonicity of the Cores of Massive Stars
Authors: Takahashi Koh , Takiwaki Tomoya , Yoshida Takashi 
Published: March 2023

Abstract
Massive stars are linked to diverse astronomical processes and objects including star formation, supernovae and their remnants, cosmic rays, interstellar media, and galaxy evolution. Understanding their properties is of primary importance for modern astronomy, and finding simple rules that characterize them is especially useful. However, theoretical simulations have not yet realized such relations, instead finding that the late evolutionary phases are significantly affected by a complicated interplay between nuclear reactions, chemical mixing, and neutrino radiation, leading to nonmonotonic initial-mass dependencies of the iron core mass and the compactness parameter. We conduct a set of stellar evolution simulations, in which evolutions of He star models are followed until their central densities uniformly reach 1010 g cm−3, and analyze their final structures as well as their evolutionary properties, including the lifetime, surface radius change, and presumable fates after core collapse. Based on the homogeneous data set, we have found that monotonicity is inherent in the cores of massive stars. We show that not only the density, entropy, and chemical distributions, but also their lifetimes and explosion properties such as the proto-neutron-star mass and the explosion energy can be simultaneously ordered into a monotonic sequence. This monotonicity can be regarded as an empirical principle that characterizes the cores of massive stars.
Repeating Emission Episodes in Gamma-Ray Bursts: Millilensing or Jet Precession?
Authors: Gao He , Li An , Lei Wei-Hua , You Zhi-Qiang 
Published: March 2023

Abstract
Recently, some gamma-ray bursts (GRBs) whose light curves consist of repeating emission episodes with similar temporal profiles have attracted extensive attention. They are proposed to be candidates of millilensing events, although smoking gun evidence is lacking, since there are no redshift measurements and no angular offset detections for any of these candidates. Here we show that without invoking gravitational lensing, the repeating light-curve properties of these GRBs could also be interpreted under the jet precession model, as long as the detectable period in every precession circle is less than the precession period, and the precession period is close to the jet emission duration. By fitting the gamma-ray light curves of these GRBs, we suggest that the jet precession angle for these bursts should be relatively small (e.g., θ

p
< 5.°3), and the jet structure for these bursts are more likely Gaussian. The results suggest us to be careful when identifying millilensing GRBs. Multiband afterglow data and especially angular offset detections are essential to provide comprehensive justification for this identification.
Coplanar Circumbinary Planets Can Be Unstable to Large Tilt Oscillations in the Presence of an Inner Polar Planet

Published: March 2023

Abstract
Mutually misaligned circumbinary planets may form in a warped or broken gas disk or from later planet–planet interactions. With numerical simulations and analytic estimates we explore the dynamics of two circumbinary planets with a large mutual inclination. A coplanar inner planet causes prograde apsidal precession of the binary and the stationary inclination for the outer planet is higher for larger outer planet orbital radius. In this case a coplanar outer planet always remains coplanar. On the other hand, a polar inner planet causes retrograde apsidal precession of the binary orbit and the stationary inclination is smaller for larger outer planet orbital radius. For a range of outer planet semimajor axes, an initially coplanar orbit is librating meaning that the outer planet undergoes large tilt oscillations. Circumbinary planets that are highly inclined to the binary are difficult to detect—it is unlikely for a planet to have an inclination below the transit detection limit in the presence of a polar inner planet. These results suggest that there could be a population of circumbinary planets that are undergoing large tilt oscillations.
Les pratiques RH dans l’ESS. Le cas d’une coopérative en pleine croissance
Authors: Barel Yvan 
Published: March 2023

En tant qu’organisations hybrides, les coopératives sont appelées à mettre en place des pratiques RH assurant une articulation entre les nécessités économiques et un projet sociopolitique qui s’enracine dans les valeurs de l’ESS. Réputée plutôt intuitive et peu formalisée, la GRH dans l’ESS est souvent associée à celle des petites entreprises. Est-elle adaptée à une structure de taille plus conséquente ? Une étude de cas réalisée au sein d’une coopérative en pleine croissance montre les vertus des pratiques RH en termes d’engagement collectif mais également les dérives militantes pouvant générer une perte d’efficacité.
Multinationales : en finir avec l’impunité ?
Authors: Thomas Frédéric 
Published: March 2023

Des lois sur le « devoir de vigilance » ont récemment été adoptées ou sont en cours de discussion. L’enjeu est de contrôler le respect des droits humains et environnementaux par les entreprises. Et d’en finir avec l’impunité. Les expectatives suscitées par ces initiatives – surtout au Nord – égalent les frustrations qu’elles risquent de soulever. Leur efficacité dépendra de leur capacité à corriger, voire à renverser l’asymétrie de pouvoir entre multinationales et organisations sociales.

L’absence de législations solides et d’obligations de « vigilance » en matière d’environnement a laissé les entreprises minières poursuivre leurs activités au mépris des dommages causés dans leurs chaînes d’approvisionnement. En Amérique latine, la mise en œuvre du processus de « devoir de vigilance » environnementale, en lien avec d’autres instruments, permettrait de freiner l’impunité des multinationales, mais les défis à relever sont de taille.
Un Inferno un po’ dickensiano. Dante e « Catene » di Rat-Man
Authors: Rigo Paolo 
Published: March 2023

Une forme particulière de parodie du texte de Dante est illustrée par l’épisode de Rat-Man intitulé « Catene », de Leo Ortolani (numéro 21 de la série). L’univers de Dante est reconnaissable comme l’hypotexte principal de cette aventure, même si celle-ci présente clairement un visage « populaire ». Cet aspect se lit dans l’utilisation des vers de Dante les plus célèbres (mais pas toujours philologiquement corrects) et dans la construction d’un arrière-plan infernal qui remonte clairement à la Comédie.

Exploratory study on factors influencing the introduction of complementary feeding amongst caregivers of children between 6 and 24 months of age in Polokwane, Limpopo province
Authors: Mphasha Mabitsela H. , Mokubela Gerald , Ramokotedi Thendo , Kgari Thapelo 
Published: March 2023

Background: Complementary feeding should be introduced at six months to meet infants’ growing nutritional needs. Inappropriate complementary feeding poses threats to the health, development and survival of infants. The Convention on the Rights of the Child states that every child has the right to good nutrition. Caregivers should ensure that infants are fed properly. Factors such as knowledge, affordability and availability impact complementary feeding. Hence, this study explores factors influencing complementary feeding amongst caregivers of children between the age of six and 24 months in Polokwane, Limpopo province, South Africa.Methods: A qualitative phenomenological exploratory study design was used to collect data from 25 caregivers, using purposive sampling; the sampling size was dependent on data saturation. Data were collected through one-on-one interviews using voice recorders and field notes for non-verbal cues. Data were analysed using the eight steps of Tesch’s inductive, descriptive and open coding technique.Results: Participants had knowledge about when and what to introduce during complementary feeding. Participants alluded that availability and affordability, maternal beliefs about infant hunger cues, social media, attitudes, returning to work because of the end of maternity leave and painful breasts affect complementary feeding.Conclusion: Caregivers introduce early complementary feeding because of returning to work at the end of maternity leave and painful breasts. Additionally, factors such as knowledge about complementary feeding, availability and affordability, mother’s beliefs about child hunger cues, social media and attitudes influence complementary feeding.Contribution: There is a need to establish credible social media platforms to disseminate appropriate complementary feeding messages. The established credible social media platforms must be promoted, and caregivers must be referred from time to time.
Clinical grading of pediatric heart failure in Egypt
Authors: Safar Heba 
Published: March 2023

Background
The inability of the heart to satisfy the demands of the target tissues’ metabolism as a result of alterations to the cardiac anatomy or function is known as heart failure (HF).

Objective
With a focus on the relationship between HF grade and other factors, the study sought to investigate clinical, laboratory, mortality, and severity of HF in children.

Patients and methods
From April 2022 to September 2022, an analytical cross-sectional study was conducted in the Pediatric Department of the Fayoum University, Faculty of Medicine. A total of 30 children with congestive HF, ranging in age from 3 days to 10 years, made up the study group. The patients’ medical information was gathered from medical records kept in hospital patient files. For grading, the original Ross Classification for pediatric HF was applied. The diagnosis was clinically and echocardiographically verified.

Results and conclusion
For clinical and therapy evaluation, the severity of HF was determined according to Ross classification. HF cases of classes II, III, and IV were reported in 53.3, 33.3, and 13.3% of the current study population, respectively. A large proportion of the research group patients had anemia (80%), hypoalbuminemia (73.3%), and higher creatinine levels (40%), whereas a lesser proportion had lower sodium and calcium levels. Hypokalemia brought on by diuretics is uncommon in the research group (6.7%). Because anemia correlates well with Ross classification and the quantity of cardiac drugs taken, it has a negative effect on the severity of congestive HF and treatment regimens, with P value less than 0.05. The other side of the coin is that additional adverse effects are brought on by higher drug use. The main causes of death in patients with congestive HF were verified to be severe infections and malnutrition by the high mean of C-reactive protein and low mean of albumin, among nonsurvived cases, with P value less than 0.05.
Combined scheimpflug and optical coherence tomography imaging in screening of keratoconus in children with Down syndrome
Authors: Azzam Sarah , Salama Tasneem , Eissa Sherif , Elessawy Kareem B. 
Published: March 2023

Purpose
The aim of this study was to screen for keratoconus (KC) in a sample of children with Down syndrome (DS) and to correlate the changes of combined Scheimpflug and optical coherence tomography imaging in these children and to compare it with an age-matched control group with healthy cornea.

Patients and methods
This was a prospective, case–control, analytic study that included 52 eyes of 26 children, who were divided into two groups: 13 with DS (group A) and 13 age-matched healthy controls (group B). Both groups were evaluated using anterior segment optical coherence tomography (AS-OCT) and Scheimpflug camera topographer (Sirius, CSO).

Results
KC-like features were detected in 61.5% of the patients in the DS group. Assessment of the corneal parameters showed statistically significant correlation between Sirius topography and AS-OCT epithelium and pachymetry maps parameters in the DS group.

Conclusion
Corneal features compatible with the diagnosis of KC were common findings in children with DS. Combined use of AS-OCT epithelial mapping and corneal topography is of high significance and can be used for screening and early detection of KC in patients with DS.
Anterior segment optical coherence tomography analysis of regional epithelial thickness in keratoconus following intracorneal ring segment implantation
Authors: Elibiary Hani M.H. , Aly Mohamed G. , Rehan Raafat A. , Najeed Hala M.A. 
Published: March 2023

Background
The changes in the epithelial thickness profile were found to be highly predictable and were responding to compensate for the changes in stromal curvature gradient.

Aim
The aim of this study was to evaluate the epithelial thickness after intracorneal ring segment (ICRS) implantation in patients with keratoconus and to correlate it with the uncorrected visual acuity (UCVA).

Patients and methods
This is a prospective nonrandomized clinical study that was conducted at the Faculty of Medicine, Ain Shams University, Cairo, Egypt. It included 24 eyes with keratoconus, which were implanted by ICRS and were scanned by CIRRUS HD-OCT 5000 preoperatively, at 1 week, 1 month, and 3 months postoperatively. The mean epithelial thickness (MET) at the cone and at the zone of ICRS implantation (5–7 mm) and UCVA were documented.

Results
The MET increased significantly from a preoperative value of 42.9±6.3–50.8±7.1 µm at 3 months postoperatively (P=0.01). In addition, the mean minimum (and not the mean maximum) epithelial thickness at the 5–7-mm zone increased significantly from 35.8±4.2 µm preoperatively to 38.7±5.4 µm at 3 months postoperatively (P=0.000). There was a statistically significant negative correlation between the MET and the mean UCVA preoperatively (r=−0.389, P=0.03), at 1 week (r=−0.415, P=0.04), and at 3 months postoperatively (r=−0.479, P=0.01).

Conclusions
The significant increase in the MET indicates the immediate, dynamic epithelial remodeling that continued up to 3 months after implantation. The increase in the minimum but not the maximum epithelial thickness confirms the epithelial remodeling rather than hyperplasia. The MET can be a prognostic factor for the visual outcome after ICRS as it correlated with the UCVA.
Distance and intermediate visual acuity after a new generation monofocal intraocular lens compared with the standard monofocal intraocular lens implantation
Authors: Elbakry Amr A. , Emad Rokaya , Salah Yehia M. , Sidky Mohamed K. 
Published: March 2023

Purpose
The aim of this study was to determine the effectiveness of a novel innovative monofocal intraocular lens (Tecnis Eyhance ICB00) compared with the standard monofocal lens (Tecnis-1-piece ZCB00) in terms of contrast sensitivity, postoperative refraction, intermediate visual acuity (VA), and uncorrected and best-corrected distance VA.

Patients and methods
This prospective comparative interventional clinical study was conducted from January 2021 to November 2021. It included 40 eyes of 20 patients who were divided into two groups, with 10 patients each. Candidates for bilateral cataract extraction by phacoemulsification were included in this study and underwent thorough preoperative examination and postoperative evaluation at 3 months after the second eye operation. The outcome measures included intermediate and distance VA, near add, contrast sensitivity, and incidence of photic phenomena, which was evaluated using a printed questionnaire. The binocular defocus curves were analyzed.

Results
The study included 20 patients (seven males and 13 females). Binocular and monocular uncorrected and corrected distance VAs were statistically similar in both groups. The Eyhance group demonstrated significantly higher binocular uncorrected and corrected intermediate VA compared with the TECNIS 1-piece group (P<0.001). Defocus and contrast sensitivity values were not significantly different between the two groups.

Conclusion
Patients who were bilaterally implanted with the new monofocal intraocular lenses achieved significantly higher intermediate VA outcomes without affection of distance VA, with similar mean contrast sensitivity values and low incidence of photic phenomena like halo and glare compared with the standard monofocal lens.
Prevalence and correlates of personality disorders in males with alcohol dependence syndrome undergoing inpatient treatment in a tertiary care hospital in South India
Authors: Balachandran Aravindan , Ramamurthy Parthasarathy , Thilakan Pradeep 
Published: March 2023

ABSTRACT

Background:
Globally, about half the patients with alcohol dependence syndrome have a comorbid personality disorder (PD). Indian studies that have explored this are sparse.

Objectives:
The present study was conducted to estimate the prevalence of personality disorders in individuals with alcohol dependence syndrome undergoing inpatient treatment and to determine the sociodemographic and clinical correlates of PDs in these patients.

Methods:
This cross-sectional observational study was conducted among the inpatients of the psychiatry department in a tertiary care teaching hospital. Adult male patients with DSM-IV TR diagnosis of alcohol dependence were evaluated for the presence of PDs using Structured Clinical Interview for DSM IV Axis II Personality disorders. The severity of alcohol dependence was assessed using the Severity of Alcohol Dependence Questionnaire.

Results:
One hundred male inpatients with alcohol dependence syndrome were recruited. Of them, 48 (48%) participants had at least one PD with a 95% confidence interval of 0.38-0.58. Antisocial and avoidant PDs were found in 26 (26%) and 13 (13%) patients, respectively. The mean age at first drink was lower in participants with PD when compared to those without any PD (18.13 ± 4.46 vs. 20.79 ± 4.61 years, respectively). Also, the amount of alcohol consumption per day was significantly higher in those with PD when compared to those without any PD (15.9 ± 6.81 vs. 13.17 ± 4.34 units per day).

Conclusion:
About half of males with alcohol dependence syndrome undergoing inpatient treatment had at least one PD. Antisocial and avoidant PDs were the most common PDs in this population. Individuals with comorbid PD had a lower age at first drink and higher daily alcohol consumption.

ABSTRACT

Aim:
This study aimed to evaluate the prevalence of subjective cognitive complaints and their association with clinical variables, insight, and disability.

Methodology:
Seven hundred and seventy-three subjects with bipolar disorder (BD), recruited across 14 centers, currently in the euthymic phase were cross-sectionally evaluated on Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA).

Results:
The mean total COBRA score was 9.79 (SD: 6.99), and 322 (41.7%) of the participants were found to have subjective cognitive complaints when the cut-off of >10 was used. Compared to those without cognitive complaints, those with cognitive complaints more often had depression as the first episode in their lifetime, had a higher prevalence of alcohol dependence, a higher number of depressive episodes (first five years of illness, lifetime, and per year of illness), a higher number of manic episodes in the first five years of illness, more often had depressive or indeterminate predominant polarity, lower prevalence of at least one-lifetime episode with psychotic symptoms, higher severity of residual symptoms, spent more time in the episodes in the lifetime, had poorer insight and higher disability.

Conclusion:
The present study suggests subjective complaints complaints are associated with more severe illness, higher levels of residual symptoms, poor insight, and higher disability.
Immediate effect of shoe raise on unaffected side in gait of poststroke hemiparesis
Authors: Jariwala Neeti , Diwan Shraddha , Shah Nehal 
Published: March 2023

PURPOSE:
The purpose of the study was to observe the immediate changes on gait speed and qualitative gait parameters with and without the use of additional shoe raise on unaffected lower limb in poststroke hemiparetic patients.

MATERIALS AND METHODS:
Thirty-one participants with chronic stroke from SBB College of Physiotherapy, of either gender (40–70 years), able to walk 20 m with or without external aids were included in the study by purposive sampling. Patients with severe spasticity, fixed contractures, and audio, visual, or perceptual impairments were excluded from the study. An observational study was conducted where patients were tested under two conditions – pre- and postinserting a 1.5 cm shoe raise on the unaffected limb. Patients explained the nature of the study, and a 10-m walk test was performed along with video recording from anterior, posterior, and lateral views, which were later analyzed using Wisconsin Gait Scale (WGS).

RESULTS:
The mean age was 52.903 ± 8.423 and poststroke duration was 28.806 ± 1.836. Out of 31 patients, 20 were male and 11 female; 17 patients had right-sided hemiparesis, in 14 left-sided hemiparesis, out of which 26 were chronic and 5 were acute poststroke patients. Values for pre- and postscores of WGS were Z= −4.88, P= 0.000, and scores for speed were Z= −4.89, P= 0.000.

CONCLUSION:
From this study, it has been concluded that shoe raising, given on unaffected lower limb to hemiparetic patients, has shown a significant difference in pre- and postgait qualitative parameters and speed in both males and females of age group 40–70 years.
