Background
The COVID-19 pandemic has significantly impacted the surgical practice throughout the world, including elective surgical care. This study investigated the characteristics of patients undergoing elective surgery, the prevalence of COVID-19 infection, the surgical procedures performed, and 30-day mortality in general and pediatric surgical settings in selected tertiary-level hospitals in Bangladesh from November 2020 to August 2021.

Methods
This serial cross-sectional study included 264 patients scheduled for elective surgeries during the study period. All patients underwent COVID-19 real-time polymerase chain reaction (RT-PCR) testing within 24 hours before surgery. Data on age, sex, common comorbidities, surgical procedures, and 30-day mortality were collected and analyzed. Furthermore, comparisons were made between COVID-19 positive and negative patients.

Results
The prevalence of COVID-19 infection among patients was 10.6%. Older age, a history of major surgery within the last three months, hypertension, and diabetes mellitus were significantly associated with COVID-19 infection. All COVID-19-negative patients underwent surgery, while only 46.4% of COVID-19-positive patients underwent surgery. The most common surgical procedures were related to the digestive system, breast, and urinary system. Only one patient (0.4%) died within 30 days after surgery among the COVID-19-negative patients, whereas two patients (7.1%) died among the COVID-19-positive patients: one before surgery and one after surgery.

Conclusions
This study provides valuable insights into the characteristics, burden of COVID-19 infection, and 30-day mortality of patients undergoing elective surgery in tertiary care centers in Bangladesh during the pandemic.
Immune Checkpoint Inhibitor-Induced Hemorrhagic Gastritis
Authors: Mathialagan Karthik , Tai Cheng-Hung , Sethi Samdish , Thomas Sumi , Loeser Caroline 
Published: August 2023

ABSTRACT
Immune checkpoint inhibitors (ICIs) have been increasingly used in the treatment of several malignancies and may target cytotoxic T-lymphocyte-associated antigen-4, programmed cell death-1, and programmed cell death ligand 1, which work on maintaining peripheral immune tolerance. ICIs inhibit these ligands causing an immune-enhancing effect, leading to a wide spectrum of complications from mild mucositis to life-threatening pneumonitis or hepatitis. These complications are collectively called immune-related adverse events. Their prevalence has increased with a rise in ICI use, with rare manifestations being reported in popular literature. We present a case of hemorrhagic gastritis due to the anti-programmed cell death-1 antibody, pembrolizumab.

Abstract
In Brazil, three out four bat species from the genus Nyctinomops are known. Most of occurrences of these species are based on captures with mist-nets. In this study, we extend the distribution of Nyctinomops aurispinosus in Brazil, providing new records for the Brazilian states of Mato Grosso (1), Roraima (1), Pará (2) and Pernambuco (1). We also confirm the use of new types of shelter by N. aurispinosus, such as rock crevices in dryland environments and river boulders. We provide new fundamental information about the biology, behavioural and ecological patterns of this species.

Effect of aggregate characteristics on properties of cemented sand and gravel
Authors: Guo Lixia , Wu Zheng , Zhong Ling , Luo Yun 
Published: August 2023

Abstract
To improve the stability of cemented sand and gravel (CSG) dam construction materials, artificial aggregates can be selected to replace missing natural aggregates, and aggregate grading optimization can be carried out to meet the needs of engineering applications. This article uses finite-element analysis software to explore the influence of aggregate characteristics on the performance and destruction characteristics of CSG materials through numerical simulation. The results show that (1) with the increase of circular natural sand gravel aggregates, the peak stress and elastic modulus of the sample increase, while the strength also increases. (2) Compared to circular aggregates, polygonal aggregates have more edges and corners, which exacerbate the deformation disharmony between mortar and aggregates; the phenomenon of stress concentration is more obvious, so under the same loading step, the degree of damage of polygonal aggregates is greater than that of circular aggregates. (3) After the freeze–thaw cycle test, the deterioration of parameters in the CSG resulted in more severe damage and strength loss of the crushed stone aggregate than the circular aggregate sample. This conclusion can provide a reference for the design of CSG mix ratio in engineering sites.
Facile synthesis of novel interpenetrating polymeric network (IPN) from semi-IPN: comparative analysis of biodegradation studies for environmental remediation
Authors: Singh Anjali , Kaith Balbir Singh , Sud Dhiraj 
Published: August 2023

Abstract
This paper reports the novel synthesis of an interpenetrating polymer network (IPN) from semi-IPN. This semi-IPN is based on naturally occurring Colocasia esculenta corn starch. The toxicity levels were compared through various biodegradation methods. The polymer network was synthesised from the corresponding semi-IPN via a green pathway by using green solvent (water) and polyvinyl alcohol (PVA) as secondary monomer. The biodegradability of synthesized IPN was tested by vermi-composting, composting and soil burial methods. The study was divided into three stages that lasted up to 70 days. The synthesised IPN degraded 78.94 %, 69.23 % and 67.24 % within 70 days by vermi-composting, composting and burying in the soil, respectively. This was confirmed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with electron dispersion analysis (SEM-EDX) for each stage. Therefore, the system could be considered for agrochemical release without affecting soil fertility.

Prozessregelung ermöglicht gleichbleibende Fertigungsqualität bei der Implantatfertigung
Authors: Denkena Berend , Klemme Heinrich , Shanib Maruan , Kaiser Sebastian 
Published: August 2023

Abstract
Implantate weisen aufgrund der oftmals filigranen Struktur eine geringe werkstückseitige Steifigkeit und damit eine hohe prozesskraftbedingte Abdrängung auf. Um Toleranzanforderungen trotzdem zu erreichen, ist daher oft ein aufwändiger Einfahrprozess notwendig. Sich verändernde Rahmenbedingungen, wie z. B. zunehmender Werkzeugverschleiß, führen im Serienprozess zu weiteren Fertigungsfehlern, was eine ständige Prozessanpassung notwendig macht. In diesem Beitrag wird ein Regelungskonzept vorgestellt, das eine kontinuierliche Prozessanpassung zur Kompensation so entstehender Abweichungen selbständig durchführt.
Schnell, fachkundig und diskret: Sind verwaltungsinterne Kontrollen der bessere Rechtsschutz?
Authors: Heitzer Sonja , Kaufhold Ann-Katrin 
Published: August 2023

Zusammenfassung
In der Bankenunion erfreut sich verwaltungsinterner Rechtsschutz großer Beliebtheit. In anderen Bereichen des Unionsrechts lässt sich Ähnliches beobachten. Aus mitgliedstaatlicher Perspektive ist das eine überraschende Entwicklung, denn beispielsweise in Deutschland verliert das behördliche Vorverfahren seit Jahrzehnten kontinuierlich an Bedeutung. Anlass, das Potential verwaltungsinterner Kontrollen zu untersuchen, gibt auch der jüngste Vorschlag des EuGH zur Änderung der eigenen Satzung. Danach wären Rechtsmittel gegen Entscheidungen des EuG in Zukunft grundsätzlich unzulässig, wenn vor dem Gerichtsprozess bereits eine unabhänige behördeninterne Kontrolle der angegriffenen Verwaltungsentscheidung stattfgefunden hat. Wie dieser Vorschlag zu bewerten ist, hängt nicht zuletzt davon ab, ob die verwaltungsinternen Gremien die in sie gesetzten Hoffnungen erfüllen. Grund genug, die Strukturen und die bisherige Tätigkeit der drei Kontrollinstanzen der Bankenunion zu analysieren und eine Zwischenbilanz zu ziehen.

Published: August 2023

Las actividades mineras están asociadas a la influencia de factores externos e internos. Las empresas no tienen control sobre los factores externos como la oferta y demanda de los metales, sin embargo, los factores internos como la optimización y gestión de sus procesos es responsabilidad de sus directivos y supervisores. Los costos es resultado de la mejora continua, gestión de los procesos, gestión de la seguridad en el trabajo, cuidado del medio ambiente y de su relacionamiento social. En este contexto es necesario contar con un modelo adecuado de costos. Esta investigación tiene por objetivo mostrar la construcción de un nuevo modelo para la gestión de los costos en una mina subterránea que facilite el seguimiento, control y toma de decisiones en las operaciones diarias. Uno de los reportes que se generan del MOGECOMS es por centro de costos este presenta el presupuesto de diciembre, lo ejecutado de diciembre y la desviación de diciembre, donde la desviación es la suma de la desviación técnica más la desviación económica de diciembre, también se presenta el presupuesto acumulado a diciembre, ejecutado acumulado a diciembre y desviación acumulada a diciembre, donde la desviación acumulada es la suma de la desviación técnica más la desviación económica. Además, el modelo de gestión de costos permite generar costos por estructuras de mineralizadas (veta, cuerpo, manto, cuerpo), costos por métodos de explotación (corte y relleno, sublevel stoping), costos fijos y costos variables, costos por naturalezas de gastos, determinar KPI de las operaciones. Mediante el análisis de estos reportes permite tomar decisiones y gestionar las operaciones de la mina, consecuentemente hacer que las operaciones mineras sean sostenibles en el tiempo.

BACKGROUND AND OBJECTIVES
To provide support to parents of critically ill children, it is important that physicians adequately respond to parents’ emotions. In this study, we investigated emotions expressed by parents, physicians’ responses to these expressions, and parents’ emotions after the physicians’ responses in conversations in which crucial decisions regarding the child’s life-sustaining treatment had to be made.

METHODS
Forty-nine audio-recorded conversations between parents of 12 critically ill children and physicians working in the neonatal and pediatric intensive care units of 3 Dutch university medical centers were coded and analyzed by using a qualitative inductive approach.

RESULTS
Forty-six physicians and 22 parents of 12 children participated. In all 49 conversations, parents expressed a broad range of emotions, often intertwining, including anxiety, anger, devotion, grief, relief, hope, and guilt. Both implicit and explicit expressions of anxiety were prevalent. Physicians predominantly responded to parental emotions with cognition-oriented approaches, thereby limiting opportunities for parents. This appeared to intensify parents’ expressions of anger and protectiveness, although their anxiety remained under the surface. In response to more tangible emotional expressions, for instance, grief when the child’s death was imminent, physicians provided parents helpful support in both affect- and cognition-oriented ways.

CONCLUSIONS
Our findings illustrate the diversity of emotions expressed by parents during end-of-life conversations. Moreover, they offer insight into the more and less helpful ways in which physicians may respond to these emotions. More training is needed to help physicians in recognizing parents’ emotions, particularly implicit expressions of anxiety, and to choose helpful combinations of responses.
Addiction substitution and concurrent recovery in gambling disorder: Who substitutes and why?
Authors: Kim Hyoun S. , McGrath Daniel S. , Hodgins David C. 
Published: August 2023

AbstractObjectivesWhen individuals recover from gambling disorder, their involvement in other potentially addictive substances and behaviors may also subsequently increase (substitution) or decrease (concurrent recovery). The objectives of this study were to identify and compare recovery processes associated with substitution and concurrent recovery in gambling disorder.MethodsA mixed-method study was conducted with 185 people who were recovered from gambling disorder. Semi-structured interviews were used to: (i) establish onset and recovery of gambling disorder as well as other substance and behavioral addictions; and (ii) assess processes (e.g., reasons, emotional state, helpfulness) associated with addiction substitution and concurrent recovery. Participants also completed a survey assessing demographic characteristics, gambling behaviors, and psychological characteristics to compare demographic and clinical differences between participants who engaged in addiction substitution, concurrent recovery, or neither (controls).ResultsThe most frequently reported reason for engaging in addiction substitution was as a substitute coping mechanism. The most reported reason for engaging in concurrent recovery was due to the addictions being mutually influenced. Negative emotional states were common when engaging in both addiction substitution and concurrent recovery. Although the three groups did not differ on gambling characteristics, addiction substitution was associated with greater underlying vulnerabilities including childhood adversity, impulsivity, emotion dysregulation, and, maladaptive coping skills.ConclusionTransdiagnostic treatments that target the underlying mechanisms of addictions may reduce the likelihood of engaging in addiction substitution.

Hypoxia is one of the critical issues in aquaculture production systems as it can lead to physiological disturbances in cultured fish. This research aimed to evaluate the tolerance level and physiological responses of domesticated Asian redtail catfish Hemibagrus nemurus reared in various hypoxia conditions. A total of 12 fish/treatment were acclimated to gradually decreased dissolved oxygen treatments until fish experienced aquatic surface respiratory (ASR) and loss of equilibrium (LOE). Cortisol, haemoglobin, and glucose levels were detected in the blood plasma to evaluate the stress response of the fish to hypoxia. The result showed that ASR of H. nemurus was identified at 2.17 ± 0.14 ppm of dissolved oxygen (DO) concentration with the percentage of ASR was 77.67 ± 9.53%, while LOE critical of H. nemurus happened at 0.63 ± 0.15 ppm of DO where 55.56 ± 4.81% of the fish experienced LOE. There were significant differences in the values of physiological parameters (blood cortisol, haemoglobin, and glucose) between control and treatments as fish experienced LOE (P<0.05). In the present study, it was found that the Asian redtail catfish is classified as a hypoxia-sensitive fish group. Tehis finding is valuable information for the rearing and growing of the fish to provide an optimal DO concentration for their growth and survival.
HUMAN GAIT ANALYSIS USING HYBRID CONVOLUTIONAL NEURAL NETWORKS

Published: August 2023

Human gait analysis is a promising method of researching on human activities like walking or sitting. It reflects the habits of one person and can be observed in any activity that person performs. The patterns in human movements are influenced by many factors, including physiology, social, psychological, and health factors. Differences in limb movements help identify gait patterns, which are often measured using inertial measurement unit sensors (IMU) like gyroscopes and accelerometers placed in various locations throughout the body.

This paper analyses the combination of IMU sensors and electromyography sensors (EMG) to improve the identification accuracy of human movements. We propose the hybrid convolutional neural network (CNN) and long short-term memory neuron network (LSTM) for the human gait analysis problem to achieve an accuracy of 0.9418, better than other models including pure CNN models. By using CNN's image classification advancements, we analyse multivariate time series sensor signals by using a sliding window to transform sensor data into image representation and principal component analysis (PCA) to reduce the data dimensionality. To tackle the dataset imbalance issue, we re-weight our model loss by the inverse effective number of samples in each class. We use the human gait HuGaDB dataset with unique characteristics, for gait analysis.
