Published: February 2025

BACKGROUND
Patients with decompensated liver cirrhosis suffering from esophagogastric variceal bleeding (EGVB) face high mortality.
AIM
To investigate the risk factors for EGVB in patients with liver cirrhosis and establish a diagnostic nomogram.
METHODS
Patients with liver cirrhosis who met the inclusion criteria were randomly divided into training and validation cohorts in a 6:4 ratio in this retrospective research. Univariate analysis, least absolute shrinkage and selection operator regression, and multivariate analysis were employed to establish the nomogram model. Calibration curve, the area under the receiver operating characteristic curve (AUC), and decision curve analysis (DCA) were applied to assess the discrimination, accuracy, and clinical practicability of the nomogram, respectively.
RESULTS
A total of 1115 patients were enrolled in this study. The nomogram was established based on white blood cells (P < 0.001), hemoglobin (P < 0.001), fibrinogen (P < 0.001), total bilirubin (P = 0.007), activated partial thromboplastin time (P = 0.002), total bile acid (P = 0.012), and ascites (P = 0.006). The calibration curve indicated that the actual observation results were in good agreement with the prediction results of the model. The AUC values of the diagnostic model were 0.861 and 0.859 in the training and validation cohorts, respectively, which were higher than that of the aspartate aminotransferase-to-platelet ratio index, fibrosis index based on 4 factors, and aspartate aminotransferase-to-alanine aminotransferase ratio. Additionally, DCA indicated that the net benefit value of the model was higher than that of the other models.
CONCLUSION
This research constructed and validated a nomogram with perfect performance for predicting EGVB events in patients with liver cirrhosis, which could help clinicians with timely diagnosis, individualized treatment, and follow-up.
PREVIC: An adaptive parent report measure of expressive vocabulary in children between 3 and 8 years of age

Abstract
Parent report measures have proven to be a valuable research tool for studying early language development. Caregivers are given a list of words and are asked which of them their child has already used. However, most available measures are not suited for children beyond infancy, come with substantial licensing costs or lack a clear psychometric foundation. Here, we present the PREVIC (Parent Report of Expressive Vocabulary in Children), an open-access, high-quality vocabulary checklist for German-speaking children between 3 and 8 years of age. The PREVIC was constructed leveraging the advantages of item response theory: we designed a large initial item pool of 379 words and collected data from 1190 caregivers of children between 3 and 8 years of age. Based on these data, we computed a range of fit indices for each item (word) and used an automated item selection algorithm to compile a final pool that contains items that (a) vary in difficulty and (b) fit the Rasch (one-parameter logistic) model. The resulting task is highly reliable and shows convergent validity. The IRT-based construction allowed us to design an adaptive version of the task that substantially reduces the task duration while retaining measurement precision. The task – including the adaptive version – was implemented as a website and is freely accessible online (https://ccp-odc.eva.mpg.de/previc-demo/). The PREVIC fills an important gap in the toolkit of researchers interested in language development and provides an ideal starting point for developing converging measures in other languages.

Exploring Mass Transfer Mechanisms in Symbiotic Systems
Authors: Vathachira Irin Babu , Hillman Yael , Kashi Amit 
Published: February 2025

Abstract
We define two regimes of the parameter space of symbiotic systems based on the dominant mass transfer mechanism. A wide range of white dwarf (WD) mass, donor mass, and donor radius combinations are explored to determine the separation for each parameter combination, below which wind Roche-lobe (RL) overflow will be the dominant mass transfer mechanism. The underlying concept is the premise that the wind accelerates. If it reaches the RL before attaining sufficient velocity to escape, it will be trapped and gravitationally focused through the inner Lagrangian point toward the accreting WD. However, if the wind succeeds in attaining the required velocity to escape from the donor’s RL, it will disperse isotropically, and the dominant mass transfer mechanism will be the Bondi–Hoyle–Lyttleton prescription, in which only a fraction of the wind will be accreted onto the WD. We present these two regimes of the 4D parameter space, covering 375 different parameter combinations.

Published: February 2025

Abstract
The tip of the red giant branch (TRGB) stars have attracted intensive attention in recent years because their I-band absolute magnitudes, M

I
, are often used for distance calibration in the Hubble constant measurements because of its almost independence on metallicity ([Fe/H]). However, a discrepancy exists between various studies, and the theoretical stellar model predicts the dependence of their luminosity on [Fe/H]. Here, we present a careful study of the dependence of absolute magnitudes and color indexes on metallicity in optical and near-infrared bands. With the TRGB stars identified in 33 Galactic globular clusters by the reddest color in the G
BP − G
RP versus G
RP diagram, it is confirmed that M

I
is almost constant of −4.017 ± 0.036 ± 0.027 mag when [Fe/H] < −1.2, which would give H
0 = 70.86 ± 1.2 ± 0.9 km s−1 Mpc−1 with this updated luminosity calibration for Type Ia supernovae. However, for [Fe/H] > −1.2, M

I
is found to become fainter with lower metallicity, which would lead to a larger Hubble constant. In the optical G
BP, G
RP, and V bands, the absolute magnitude of TRGB stars tends to increase with metallicity, while in the infrared J, H, and K

s
bands, the variation with metallicity shows an inverse tendency. In addition, the analytical relations of the color indexes with metallicity are presented, which have smaller dispersion than those derived for the corresponding absolute magnitudes.
Modeling Complex Organic Molecules’ Formation in Cold Cores: Multiphase Models with Nonthermal Mechanisms

Published: February 2025

Abstract
In recent years, a significant number of oxygen-bearing complex organic molecules (COMs) have been detected in the gas phase of cold dark clouds such as TMC-1. The formation of these COMs cannot be explained by diffusive mechanisms on grains and gas-phase reactions. This study investigates the formation of oxygen-bearing COMs in cold dark clouds using multiphase gas–grain models that incorporate cosmic ray-induced nondiffusive radiation chemistry and nonthermal sputtering desorption mechanisms. Additionally, we present the effects of varying elemental C/O ratio and different sputtering rates. We utilized an accelerated Gillespie algorithm, based on the regular Gillespie algorithm. The results of our models for dimethyl ether (CH3OCH3), methyl formate (HCOOCH3), acetaldehyde (CH3CHO), ethanol (C2H5OH), and methanol (CH3OH) show reasonable agreement with observations toward TMC-1, within a factor of 3. Out of the 94 species compared with observations, 63 show agreement within 1 order of magnitude, accounting for 67.02%. Overall inclusion of nonthermal mechanisms in multiphase models shows notable improvement of modeling on oxygen-bearing COMs in the interstellar medium.
A survival framework for SMME’s based on COVID-19 events in the Western Cape of South Africa
Authors: Strydom Carin , Van der Merwe Stephan 
Published: February 2025

Background: Many small-, medium- and micro-sized enterprises (SMMEs) struggled for survival in South Africa during the coronavirus disease 2019 (COVID-19) pandemic. Unexpectedly, several SMMEs in the Western Cape province of South Africa not only survived but also thrived. Investigation was therefore needed to better understand how they survived to fill the knowledge gap.Aim: This research aimed at ascertaining the reasons why and how SMMEs survived a prolonged pandemic. It thereby investigated the possibilities of developing a framework for SMME survival during crises such as a prolonged pandemic.Setting: The study involved 16 different types of successful SMMEs, which operated in the Western Cape, South Africa, before, during and after the COVID-19 pandemic.Methods: The study employed semi-structured interviews with 16 participants as SMME owners, following a qualitative approach. Qualitative data were generated via snowball sampling following the COVID-19 pandemic and were analysed manually.Results: Study’s findings enabled the development of a proposed survival framework for SMMEs during times of crisis, such as a pandemic.Conclusion: The study succeeded in better understanding the challenges experienced by the SMMEs during the COVID-19 pandemic. It revealed several survival factors and actions, including the contribution of the Western Cape Government’s attempts towards an entrepreneurial ecosystem.Contribution: Drawing in part on resilience theory, a possible survival framework is proposed for entrepreneurs to consider whereby they may establish self-constructed support for the continuity of their SMMEs during prolonged times of crisis.

Abstract

Background:
Various factors have been identified as contributors to mortality in coronavirus disease 2019 (COVID-19). This study aims to elucidate the relationship between admission investigations, hourly oxygen saturation (SpO2), and circadian rhythm in COVID-19 mortality.

Materials and Methods:
A retrospective cross-sectional study was conducted using sociodemographic and laboratory data from the medical records department of a tertiary care hospital. Data from 218 COVID-19 fatalities during the second wave (March 2021–June 2021) were analyzed using means, percentages, averages, correlation, and coefficients of determination with SPSS software version 20.0.

Results:
The majority of deaths occurred in males, the unemployed, those over 60 years, and patients with comorbidities. The study also examined contributing factors in 35.3% of patients who died without comorbidities. Elevated levels of lactate dehydrogenase, interleukin-6, high-sensitivity C-reactive protein, D-dimer, and ferritin were predictive of hypoxemia progression. A notable dip in mean SpO2 at midday indicated circadian rhythm disruption in COVID-19 patients.

Conclusions:
A midday dip in SpO2, likely due to circadian rhythm disruption, was a notable feature in patients who died due to COVID-19. Elevated inflammatory markers are significant predictors of hypoxemia progression.

Le défi actuel des acteurs de la filière cacao au Cameroun est de trouver des stratégies pour augmenter la production en cabosses matures et mûres des systèmes agroforestiers à base de cacaoyers (SAFc) camerounais afin de mieux répondre à la forte demande mondiale en fève de cacao. L’objectif de cette étude était de caractériser la diversité des cacaoyers et évaluer la dendrologie de variantes de cacaoyers identifiées dans un SAFc en zone de forêt dense et humide camerounaise. Un inventaire d’aménagement forestier a été fait du 02 septembre au 25 octobre 2020 afin de collecter les informations sur les cacaoyers de l’Exploitation Agricole BETTI (EAB). 3597 tiges de cacaoyers ont été dénombrées, représentant une densité moyenne de 309,11 tiges/ha et une surface terrière moyenne de 6,81 m2 / ha. La caractérisation floristique des cacaoyers faite suivant des critères morphologiques des cabosses a permis d’identifier 18 variantes différentes de cacaoyers dont cinq : BoLiAl, BoPrOv, VePrOv, VbPrAl, BoPrAl ont des indices d’efficacités plus élevées dans un environnement complexe et très contraignant, c'est-à-dire qu’elles ont une production élevée en termes du nombre de cabosses et une bonne résistance de ces cabosses aux maladies et ravageurs. Le suivi de chacune de ces cinq variantes dans des parcelles sous traitements d’ombrage différent serait intéressant pour définir des modèles de SAFc qui combinent les ambitions de production du cacao de qualité et en quantité et de conservation d’un niveau élevé de la biodiversité en milieu forestiers.

La biopsie ostéo-médullaire associée à l’étude histologique reste un atout majeur dans la mise en évidence des pathologies de la moelle osseuse. L’objectif de cette étude était de montrer l’intérêt de la biopsie ostéo-medullaire colorée à la réticuline dans le diagnostic de ces affections. Une étude transversale a eu pour cadre le laboratoire central du Plateau et l’UFR des Sciences Pharmaceutiques et Biologiques d’Abidjan. Elle a réuni 35 blocs d’inclusion à paraffine contenant des biopsies ostéo-médullaires (BOM) sur lesquels des coupes histologiques ont été réalisées. Les colorations d’hématoxyline-éosine et de la réticuline ont été effectuées pour examen microscopique. L’âge moyen des patients était de 45,1 ± 16,9 ans avec des extrêmes de 19 et 77 ans. L’aspect histologique après coloration à l’Hématoxyline-éosine (H&E) a indiqué 13 cas de fibrose médullaire (37,1%) et la coloration de la réticuline a confirmé 6 six (6) cas de fibrose réticulinique (17,2%). La coloration de la réticuline a mis en exergue six cas de fibrose réticulinique. Cette fibrose réticulinique, s'observe lors des syndromes myéloprolifératifs, en particulier de la myélofibrose avec métaplasie myéloïde. Pour identifier les fibroses non réticuliniques, il aurait fallu associer à la coloration de la réticuline celle du trichome de Masson.

Introducción: el ejercicio físico es crucial para el envejecimiento saludable, ofreciendo múltiples beneficios en la aptitud física y el bienestar general de adultos mayores.
Objetivo: evaluar los efectos de tres tipos de ejercicio físico (baile, ejercicios-coordinativos y programa-multimodal) sobre capacidad funcional y bienestar general en adultos mayores de una ciudad colombiana.
Metodología: estudio cuasi experimental con 450 adultos mayores que asistieron a encuentros diarios en tres grupos de tercera edad, participaron voluntariamente y firmaron consentimiento informado; se aplicó Senior-Fitness-Test y escala T-WHO5.
Resultados: el ejercicio multimodal tuvo mayor impacto en el mejoramiento de las capacidades físicas mientras que el baile en el bienestar psicológico; la intervención centrada en coordinación fue la menos efectiva.
Discusión: En concordancia con otros autores se identificaron no solo los efectos principales de cada intervención, sino también cómo las variables de tiempo, edad y las interacciones entre estas influyen en los resultados obtenidos.
Conclusiones: las intervenciones no producen el mismo impacto en todos los grupos de edad; en las personas mayores, es necesario adaptar los programas de actividad física a las características y habilidades particulares para optimizar su efectividad.
