Resumen

La impactación de cuerpos extraños en el aparato digestivo es una urgencia frecuente. La localización más frecuente es el esófago, siendo mucho menos habituales otros tramos del aparato digestivo como pueden ser cardias, píloro, válvula íleo-cecal, recto o sigma.

En el caso de los cuerpos extraños localizados en tramos distales, la presentación clínica habitualmente es inespecífica (dolor abdominal o diarrea) y suele ser necesaria la realización de pruebas de imagen para su orientación y correcto diagnóstico.

En función de la localización y la morfología del cuerpo extraño, la endoscopia puede ser el método de elección para su extracción bajo visión directa.

Se presenta el caso de una mujer de 69 años con cuadro de dolor abdominal en flanco izquierdo y diarrea secundario a impactación colónica de hueso de pollo, resuelto mediante extracción endoscopia.

Neomisticismo en la poesía hispánica postsecular. Contextualización y propuesta metodológica
Authors: Helgueta Manso Javier 
Published: January 2024

En las últimas décadas, el concepto de secularización se ha revisado en Occidente. En un contexto de “reencantamiento” del mundo en el que la religiosidad ha mutado (hibridez, individualismo, espiritualidad a la carta), hay que apostar por teorías de la postsecularidad. A dicho mestizaje y nueva experiencia espiritual han contribuido las expresiones artísticas, incluida la literatura. En este trabajo, no solo se establece este marco teórico para el análisis de la nueva poesía mística, sino que también se argumenta el uso de dos herramientas que permitan una aproximación socio-estética al fenómeno. En primer lugar, se apuesta por el empleo de los términos “neomística” o “neomisticismo” para la estética postsecular. En segundo lugar, se subraya la necesidad de un método para clasificar a los poetas neomísticos; en este sentido, se exponen cuatro parámetros: estado de creencia y confesión del poeta; sustrato religioso y fuentes literarias de su creación; procedimientos constructivos del poema; niveles de la experiencia trascendente de autor y receptor, y, como consecuencia, establecimiento de unas tentativas taxonómicas. Estos parámetros se investigan en numerosos poetas (Cadenas, Cardenal, Cross, Eielson, Janés, Gervitz, Maillard, Mujica, Negroni, Paz, Valente, Scala, etc.) de varios países de habla hispana. Este artículo aspira a considerar un replanteamiento del paradigma de los estudios sobre el neomisticismo poético, así como a fijar una metodología que debe ser aplicada a nuevas obras literarias. Es por ello por lo que espera la retroalimentación de la comunidad académica para confirmar, precisar o reformular su propuesta.
Adapting attentional control settings in a shape-changing environment
Authors: Mu Yunyun , Schubö Anna , Tünnermann Jan 
Published: January 2024

AbstractIn rich visual environments, humans have to adjust their attentional control settings in various ways, depending on the task. Especially if the environment changes dynamically, it remains unclear how observers adapt to these changes. In two experiments (online and lab-based versions of the same task), we investigated how observers adapt their target choices while searching for color singletons among shape distractor contexts that changed over trials. The two equally colored targets had shapes that differed from each other and matched a varying number of distractors. Participants were free to select either target. The results show that participants adjusted target choices to the shape ratio of distractors: even though the task could be finished by focusing on color only, participants showed a tendency to choose targets matching with fewer distractors in shape. The time course of this adaptation showed that the regularities in the changing environment were taken into account. A Bayesian modeling approach was used to provide a fine-grained picture of how observers adapted their behavior to the changing shape ratio with three parameters: the strength of adaptation, its delay relative to the objective distractor shape ratio, and a general bias toward specific shapes. Overall, our findings highlight that systematic changes in shape, even when it is not a target-defining feature, influence how searchers adjust their attentional control settings. Furthermore, our comparison between lab-based and online assessments with this paradigm suggests that shape is a good choice as a feature dimension in adaptive choice online experiments.

Summary. The infectious nature of COVID-19 leads to complications in the immune system. It is relevant to determine the long-term consequences of COVID-19, which can be triggers for the urgent surgical pathology’s development of the thoracic and abdominal organs in patients with certain risk factors associated with characteristic disorders of immunometabolic reactions.
The aim. To determine the spectrum of immune resistance disorders and to find out the effect of cytotoxicity and pathogenicity of DAMP fractions on the post-COVID-19 syndrome formation and complications of the main disease in patients with urgent surgical pathology.
Materials and methods. Patients (n = 143) with urgent cardiovascular and abdominal surgical pathology that arose against the background of post-COVID-19 syndrome were examined. We used: spectrophotometry (content of DAMP fractions), immunoturbimetry (concentration of C3 and C4 complement components); luminescent microscopy (phagocytic activity of neutrophils); light microscopy (spontaneous activity of NADPH-oxidase systems of neutrophils); flow cytometry (expression of T lymphocyte activation markers); immunofluorescence (determination of antinuclear antibodies).
Results. It was found that the predominance of certain DAMP fractions is the cause of the immunopathological patterns formation in the development of post-COVID-19 syndrome. In patients with urgent surgical pathology and the predominance of the DAMP260 oligonucleotide fraction, significant changes in the hemogram, failure of endocytosis and incomplete phagocytosis of neutrophils, increased expression of the T lymphocytes late activation marker (CD3+HLA-DR+) were found. In all examined patients, a high frequency of autoantibodies to nuclear structures (ANA) was found, which depended on the content of DAMP fractions. The maximum repertoire of antibodies was found in patients with the oligonucleotide fraction (DAMP260) predominance.
Conclusions. In patients with urgent surgical pathology, during the formation of post-COVID-19 syndrome, the chronic immunoinflammatory reaction formation occurs against the background of the activation cascades development of innate and adaptive immunity factors.
PREDICTION OF THE RISK OF SEVERE PERITONITIS IN ACUTE INFLAMMATORY DISEASES OF THE ABDOMINAL CAVITY
Authors: Karol I. V. , Bilyayeva O. O. 
Published: January 2024

Abstract. Introduction. One of the most challenging problems of surgery is peritonitis, which can be a complication of acute inflammatory diseases of the abdominal cavity and is accompanied by high mortality. The development of prognostic models of peritonitis is a modern task of precision medicine.
Aim. To determine the risk of severe peritonitis in patients undergoing surgery for acute abdominal diseases.
Materials and methods. The study involved 139 patients who had been operated on for acute abdominal diseases (acute appendicitis and cholecystitis, perforated gastric or duodenal ulcer, etc.). Depending on the number of points on the modified APACHE II scale, patients were divided into two groups: Group 1 - 1-3 points (63 patients, 45.3%) and Group 2 - 4 or more points (76 patients, 54.7%). The rs1927911, rs2149356 and rs4986790 polymorphisms were determined by polymerase chain reaction using the Gene Amp® PCR System 7500 amplifier (Applied Biosystems, USA) and TaqMan Mutation Detection Assays Life-Technology (USA). Statistical processing of the study results was performed using the EZR v.1.54 software (Vienna, Austria).
Results. Univariate regression analysis revealed a higher (p=0.008) risk of severe peritonitis for men (OR 2.56; 95% CI 1.29-5.11) compared with women; an increase (p=0.031) in the risk of severe peritonitis with patient age (OR 1.02; 95% CI 1.00-1.05). The risk of severe peritonitis increased (p<0.05) with higher admission temperature, heart rate, international normalised ratio, and leukocytosis. A reduction (p=0.009) in the risk of severe peritonitis was found with a higher prothrombin index (OR 0.95; 95% CI 0.92-0.99). In addition, a decrease (p=0.015) in the risk of severe peritonitis was found in carriers of the G/A+A/A rs1927911 heterozygote of the TLR4 gene (OR 0.42; 95% CI 0.21-0.84) compared with carriers of the ancestral G/G genotype. The multivariate model included the rs1927911 genotype, age, sex, heart rate, and leukocytosis (AUC=0.83; 95% CI 0.75-0.89; p<0.001); the model sensitivity was 68.4% (95% CI 56.7%-78.6%), and specificity was 88.9% (95% CI 78.4%-95.4%).
Conclusion. Thus, prognostic risk factors for severe peritonitis were identified and a mathematical model for its prediction was developed using clinical, laboratory and genetic parameters.
COMPARISON OF SAFETY OF MINILAPAROSCOPIC AND CONVENTIONAL LAPAROSCOPIC CHOLECYSTECTOMY
Authors: Mendel M. A. , Pavlovych Yu. V. , Romanenko Ya. V. 
Published: January 2024

Abstract. Aim: to assess the safety of mini-laparoscopic cholecystectomy (MLC) compared to traditional laparoscopic cholecystectomy (LC) based on a critical view of safety (CVS).
Materials and methods: an analysis of 46 video recordings of MLC surgeries and 156 LC surgeries performed for chronic calculous cholecystitis and gallbladder polyps between 2015 and 2022 was conducted, using the concept of CVS and the quality of its achievement. An analysis of anatomical variations was also performed.
Results and discussion: the average age was 38.5 years in the MLC group and 53.8 years in the LC group, with an average operation time of (59.4±2.13) minutes and (63.01±2.01) minutes, respectively. CVS was achieved in 97.8 % of cases in MLC and 93.0 % in LC. Anatomical variations were present in 31.1 % of cases in MLC and 30.1% in LC. There were no complications of MLC, conversions from MLC to LC, or open surgery.
Conclusions: The frequency of achieving CVS in MLC was higher than in LHE (97.8 % vs. 93.0 %). Anatomical variations of the biliary system should always be considered for the safe cholecystectomy. MLC is a safe technique that is not inferior to standard LCE in elective surgery in patients with a normal BMI, and at the same time has better cosmetic results.

Published: January 2024

The idea behind Markov chain model and system of equations cannot be emphasized in terms of modeling physical systems like the Nigerian Current Account formation; since each finite state communicates for suitable decisions making. So this paper studied stochastic analysis of Markov chain on NCA data (2004-2022). The NCA data were transformed into 3-steps transition probability matrix solution to cover the number of independent years. From the transition matrix of stochastic analysis showed that in 2004-2012 has the highest probability of reducing in payments by 72%, the year 2005-2013 has the highest probability of reducing by 66% and finally in 2014-2022 has the highest probability of no-change in payments of goods and services by 3.3%. The future NCA data changes were known by introducing the concepts of percentages in each interval of years as column vectors where system of linear equations were developed and solutions were obtained to guide Nigerian economy on various levels of imports and exports of goods and services. Lastly, other statistical disparities were also considered and well discussed accordingly. These results are informative to Nigerian economy to effectively take vital decisions in their investment plans.
Insight into the Formation of β Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the β Pic Moving Group Member HD 181327

Published: January 2024

Abstract
It has been suggested that β Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star β Pic and therefore the planet’s parent protoplanetary disk, β Pic b’s C/O ratio suggests that it formed via core accretion between its parent protoplanetary disk’s H2O and CO2 ice lines. However, β Pic b’s high metallicity is difficult to reconcile with its mass M
p = 11.7 M
Jup. Massive stars can present peculiar photospheric abundances that are unlikely to record the abundances of their former protoplanetary disks. This issue can be overcome for early-type stars in moving groups by inferring the elemental abundances of the FGK stars in the same moving group that formed in the same molecular cloud and presumably share the same composition. We infer the photospheric abundances of the F dwarf HD 181327, a β Pic moving group member that is the best available proxy for the composition of β Pic b’s parent protoplanetary disk. In parallel, we infer updated atmospheric abundances for β Pic b. As expected for a planet of its mass formed via core-accretion beyond its parent protoplanetary disk’s H2O ice line, we find that β Pic b’s atmosphere is consistent with stellar metallicity and confirm that it has superstellar carbon and oxygen abundances with a substellar C/O ratio. We propose that the elemental abundances of FGK dwarfs in moving groups can be used as proxies for the otherwise difficult-to-infer elemental abundances of early-type and late-type members of the same moving groups.
Asteroseismology Applied to Constrain Structure Parameters of δ Scuti Stars

Published: January 2024

Abstract
Asteroseismology is a powerful tool to probe stellar structure. Spaceborne instruments like CoRoT, Kepler, and TESS have observed the oscillations of numerous stars, among which δ Scutis are particularly interesting, owing to their fast rotation and complex pulsation mechanisms. In this work, we inferred model-dependent masses, metallicities, and ages of 60 δ Scuti stars from photometric, spectroscopic, and asteroseismic observations using least-squares minimization. These statistics have the potential to explain why only a tiny fraction of δ Scuti stars pulsate in a very clean manner. We find most of these stars with masses around 1.6 M
⊙ and metallicities below Z = 0.010. We observed a bimodality in age for these stars, with more than half the sample younger than 30 Myr, while the remaining ones were inferred to be older, i.e., hundreds of Myrs. This work emphasizes the importance of the large-frequency separation (Δν) in studies of δ Scutis. We also designed three machine-learning (ML) models that hold the potential for inferring these parameters at lower computational cost and much more rapidly. These models further revealed that constraining dipole modes can help in significantly improving age estimation and that radial modes succinctly encode information regarding luminosity and temperature. Using the ML models, we also gained qualitative insight into the importance of stellar observables in estimating mass, metallicity, and age. The effective temperature T
eff strongly affects the inference of all structure parameters, and the asteroseismic offset parameter ϵ plays an essential role in the inference of age.
A Model-independent Method to Determine H
0 Using Time-delay Lensing, Quasars, and Type Ia Supernovae
Authors: Li Xiaolei , Keeley Ryan E. , Shafieloo Arman , Liao Kai 
Published: January 2024

Abstract
Absolute distances from strong lensing can anchor Type Ia Supernovae (SNe Ia) at cosmological distances giving a model-independent inference of the Hubble constant (H
0). Future observations could provide strong lensing time-delay distances with source redshifts up to z ≃ 4, which are much higher than the maximum redshift of SNe Ia observed so far. In order to make full use of time-delay distances measured at higher redshifts, we use quasars as a complementary cosmic probe to measure cosmological distances at redshifts beyond those of SNe Ia and provide a model-independent method to determine H
0. In this work, we demonstrate a model-independent, joint constraint of SNe Ia, quasars, and time-delay distances from strong lensed quasars. We first generate mock data sets of SNe Ia, quasar, and time-delay distances based on a fiducial cosmological model. Then, we calibrate the quasar parameters model independently using Gaussian process (GP) regression with mock SNe Ia data. Finally, we determine the value of H
0 model-independently using GP regression from mock quasars and time-delay distances from strong lensing systems. As a comparison, we also show the H
0 results obtained from mock SNe Ia in combination with time-delay lensing systems whose redshifts overlap with SNe Ia. Our results show that quasars at higher redshifts show great potential to extend the redshift coverage of SNe Ia and thus enable the full use of strong lens time-delay distance measurements from ongoing cosmic surveys and improve the accuracy of the estimation of H
0 from 2.1% to 1.3% when the uncertainties of the time-delay distances are 5% of the distance values.
Enhancing Triangulation of Interplanetary Type III Bursts through Wavevector Correction

Published: January 2024

Abstract
Interplanetary Type III bursts, generated by relativistic electron beams at solar flare reconnection sites, are explored through an investigation of 152 instances observed by the Solar Terrestrial Relations Observatory mission. This study reveals that the absolute values of the wavevector deviations from the Sun–spacecraft line are statistically 3.72 and 2.10 larger than predicted by the density model, assuming fundamental and harmonic emission, respectively. Through Monte Carlo simulations, we examine the impact of scattering by density inhomogeneities on the apparent locations of radio emissions in the interplanetary medium. The findings indicate that relative density fluctuations of 0.40 can account for the observed angular shift, a conclusion supported by the multiple flux-tube solar wind model, which confirms the presence of such magnitude of relative perpendicular density fluctuations in the solar wind. We propose a wavevector correction that incorporates this effect to enhance the triangulation of interplanetary Type III bursts, demonstrating that radio triangulation, with this correction, can reliably track electron beams in the interplanetary medium.
Engineering Anticytokine Antibodies for Immune Modulation
Authors: Tomala Jakub , Cao Shanelle D , Spangler Jamie B 
Published: January 2024

Abstract
The delicate balance of immune homeostasis is regulated by the interactions between cytokines and their cognate cell surface signaling receptors. There is intensive interest in harnessing cytokines as drugs for diseases such as cancer and autoimmune disorders. However, the multifarious and often contradictory activities of cytokines, coupled with their short serum half-lives, limit clinical performance and result in dangerous toxicities. There is thus growing emphasis on manipulating natural cytokines to enhance their selectivity, safety, and durability through various strategies. One strategy that has gained traction in recent years is the development of anticytokine Abs that not only extend the circulation half-life of cytokines but also specifically bias their immune activities through multilayered molecular mechanisms. Although Abs are notorious for their antagonistic activities, this review focuses on anticytokine Abs that selectively agonize the activity of the target protein. This approach has potential to help realize the clinical promise of cytokine-based therapies.
Rational Engineering of Islet Tolerance via Biomaterial-Mediated Immune Modulation

Published: January 2024

Abstract
Type 1 diabetes (T1D) onset is characterized by an autoimmune attack on β islet cells within the pancreas, preventing the insulin secretion required to maintain glucose homeostasis. Targeted modulation of key immunoregulatory cell populations is a promising strategy to restore tolerance to β cells. This strategy can be used to prevent T1D onset or reverse T1D with transplanted islets. To this end, drug delivery systems can be employed to transport immunomodulatory cargo to specific cell populations that inhibit autoreactive T cell–mediated destruction of the β cell mass. The rational engineering of biomaterials into nanoscale and microscale drug carriers can facilitate targeted interactions with immune cells. The physicochemical properties of the biomaterial, the delivered immunomodulatory agent, and the target cell populations are critical variables in the design of these delivery systems. In this review, we discuss recent biomaterials-based drug delivery approaches to induce islet tolerance and the need to consider both immune and metabolic markers of disease progression.
