The role of carbohydrate antigen 19-9 in the clinical evaluation of mature cystic teratomas: an observational study at a tertiary care centre
Authors: Manohar Sumana , S. Shanaz Nazeen 
Published: November 2023

Background: Carbohydrate antigen (CA) 19-9 is a tumour marker mainly used in the evaluation of gastrointestinal tract malignancies including pancreas, colon and biliary tract. Cases of ovarian tumours such as mucinous neoplasms have been reported to have high levels of CA 19-9. However, its role in the management of cystic teratomas (MCT) which are the most common benign ovarian tumours encountered in gynaecology, is not studied in depth in literature.
Methods: In our study, we observed the levels of CA 19-9 in 40 patients presenting with MCT. Its association to the cyst size, contents, laterality and torsion or rupture were documented.
Results: The various clinical parameters evaluated in our study such as larger cyst size, presence of torsion and tooth as a content had a positive association with elevated CA 19-9 levels (p<0.05). However, CA 19-9 had no significant relationship with the laterality of the cyst. Thus, CA 19-9 may serve as an important adjunct tool to ultrasonography in the management of dermoid cysts (MCT), particularly in those with larger sizes and at risk of torsion.
Conclusions: High levels of CA 19-9 can be observed in benign ovarian tumors like mature cystic teratoma (MCT) and it need not always be associated with malignancy or malignant transformation of benign tumors. Levels more than 100 IU may warrant further imaging studies to rule out gastro-intestinal pathologies. Unnecessary medical investigations or patient anxiety can be avoided in cases of moderate elevation in CA 19-9 levels.
Interstitial ectopic pregnancy: a case series
Authors: Gnanavel Gitanjali 
Published: November 2023

Interstitial ectopic pregnancy is very rare with incidence of 2-5%. Their presentation is not uniform and hence may go unrecognized till complications develop. We present three cases of interstitial ectopic pregnancies presenting in our hospital in a span of 1 year. Only one of them had pain in the abdomen at the time of presentation. All cases presented at around five to six weeks of gestation. Ultrasonography confirmed the diagnosis. One case was managed medically while in other two cases, there was a need of surgical management. There were no complications in all the cases. Thus, early presentation of cornual ectopic pregnancy results in satisfactory outcome. Hence, all pregnant women should undergo regular antenatal checkups with early scans once the urine pregnancy test come positive to confirm whether it is an intra uterine pregnancy or not.

Published: November 2023

Background: Orbital trauma accounts for approximately 3% of all emergency department visits, with approximately 4.4 million annual visits in the United States alone. We aim to describe the treatment of adult patients with orbital floor fractures between 2016 and 2021.
Methods: A retrospective, descriptive, cross-sectional, and observational study was conducted on the medical records of adult patients with orbital floor fractures between 2016 and 2021 in a referral center in Mexico city.
Results: The study included 53 patients, 5 females (8%) and 48 males (92%), with a median age of 37 years at the time of diagnosis. Among the reported trauma mechanisms, falls and violence were the most common. 4 patients (7.5%) had impure right unilateral fractures, 4 patients (7.5%) had impure left unilateral fractures, 18 patients (33.9%) had pure left unilateral fractures, 22 patients (41.5%) had pure right unilateral fractures. Five patients (9.4%) had pure bilateral fractures. Six (11.3%) received non-surgical treatment, while 47 (88.6%) underwent surgical treatment. The most common surgical approach was the transconjunctival with lateral extension.
Conclusions: There was a predominance of male patients and physical aggression as the primary trauma mechanism. Automated vehicle accidents were associated with more complex fractures. The most common type of orbital floor fracture was pure right unilateral. Most patients underwent open reduction with internal fixation.

Published: November 2023

Background: Ureterorenoscopy is a frequently used technique for the treatment of urolithiasis which provides high success rates when used under proper indications. Febrile urinary tract infection (FUTI) and urinary sepsis is the most frequent among its scarce complications. It often results secondary to urinary tract obstruction associated with urolithiasis, but also may occur after urinary tract manipulation such as ureterorenoscopy, clinical presentation varies from self-limited fever to the development of septic shock with the need for vasoactive agents or even to the patient’s death. This study has been designed to determine our rate of postoperative FUTI and sepsis after ureterorenoscopy, as well as to identify those factors that have been associated with its development.
Method: Prospective study done on 219 patients who underwent ureterorenoscopy for urinary lithiasis in government medical college, Kottayam from February 2021-March 2022. Personal, clinical, surgical and microbiological data were collected. Patients who develop FUTI, urinary sepsis during 30 days following intervention were identified. Statistical analysis will be performed by chi squared test/fishers exact test; logistic regression as appropriate.
Results: Our studies show incidence rates of postoperative FUTI in 11% and sepsis in 1.3%. Following statistical analysis, it was discovered that double J urinary diversion, a positive preoperative urine culture, diabetes, prolonged operational time, and intraoperative dilatation were all high-risk factors for the development of UTI after instrumentation.
Conclusions: Ureteroscopy-associated urosepsis is a nosocomial infection. With the increasing popularity of ureteroscopic procedures, it is imperative that patients with increased risk are addressed appropriately, and suspected sepsis must be speedily and aggressively managed.

Authors: Niu Zhongfeng , Sun Siwei , Hu Lei 
Published: November 2023

Aim
The additive differential cryptanalysis is a significant technique used in the analysis of ARX ciphers. In this paper, we will focus on accurately and efficiently calculating the additive differential probability of $$ x \lll d \oplus y \lll e $$ .
Methods
Inspired by the work of Niu et al . at Crypto 2022, we use a delicate partition of $$ \mathbf{F}_2^m \times \mathbf{F}_2^m $$ into subsets.
Result
We derive an algorithm that can calculate it with linear time complexity. Compared with our algorithm, the one proposed by Velichkov et al . is only suitable when $$ e=0 $$ .
Conclusion
For the ARX construction: $$ (x \boxplus y) \lll d \oplus y \lll e $$ , which appears in Alzette, Speck, etc. , our algorithm can find more accurate additive differential characteristics for such ARX constructions. It is essential to evaluate the resistance of such ARX primitives against Additive differential cryptanalysis.

Published: November 2023

In the face of climate change, bringing more useful alleles and genes from wild relatives of wheat is crucial to develop climate-resilience varieties. We used two populations of backcrossed recombinant inbred lines (BIL1 and BIL2), developed using two intra-specifically diverse Aegilops tauschii accessions from lineage 1 and lineage 2, respectively, and backcrossing to common wheat cultivar ‘Norin 61’. The study aimed to identify quantitative trait loci (QTL) associated with heat stress (HS) tolerance. The two BILs were evaluated under heat stress environments in Sudan for phenology, plant height (PH), grain yield (GY), biomass (BIO), harvest index (HI), and thousand kernel weight (TKW). Grain yield was significantly correlated with BIO and TKW under HS; therefore, stress tolerance index (STI) was calculated for these traits as well as for GY. A total of 16 heat tolerant lines were identified based on GY and STI-GY. The QTL analysis performed using inclusive composite interval mapping identified a total of 40 QTLs in BIL1 and 153 QTLs in BIL2 across all environments. We detected 39 QTLs associated with GY-STI, BIO-STI, and TKW-STI in both populations (14 in BIL1 and 25 in BIL2). The QTL associated with STI were detected on chromosomes 1A, 3A, 5A, 2B, 4B, and all the D-subgenomes. We found that QTL detected only under HS for GY on chromosome 5A, TKW on 3B and 5B, PH on 3B and 4B, and grain filling duration on 2B. The higher number of QTLs identified in BIL2 for heat stress tolerance suggests the importance of assessing the effects of intraspecific variation of Ae. tauschii in wheat breeding as it could modulate the heat stress responses/adaptation. Our study provides useful genetic resources for uncovering heat-tolerant QTLs for wheat improvement for heat stress environments.

Authors: Barianaki Eirini Aikaterini , Kyvelou Stella Sofia , Ierapetritis Dimitrios G. 
Published: November 2023

Understanding aspects of maritime/underwater cultural heritage (MUCH) and the associated cultural values and integrating them into maritime spatial planning (MSP) endeavors, is a new global challenge, alongside the rapid increase of human activities at sea and climate change impacts on the seas and the oceans. The article highlights the significance of cultural values in shaping human interactions with the marine environments, and how MSP can address the cultural dimensions of marine resources management. To this end, a systematic literature review was carried out to address the research question on how maritime/underwater cultural heritage is incorporated into MSP and map relevant academic literature. Following, a methodology that entailed an academic database search and the application of exclusion criteria, 346 articles resulted from Scopus. These articles were classified using science mapping techniques (i.e the VOSviewer Software ) and several categories (clusters) were created. The research showed a diversity of literature addressing the relationship between MUCH and MSP with a strong focus on sustainability, the significance of cultural ecosystem services (CES) and cultural values, the role of indigenous and local communities, but also of local stakeholders, the transfer of traditional knowledge to MSP and the participatory approaches and tools. The article concludes that for MSPlans to be innovative and acceptable by local communities, the “missing layer”of socio-cultural values and data is indispensable. In the MSP process, MUCH should be understood within this broader framework of socio-cultural considerations and values.
Corrosion Inhibition of Benzyl Quinoline Chloride Derivative-Based Formulation for Acidizing Process
Authors: Yang Zhen , Wang Yefei , Yang Jiang , Wang Jing , Finšgar Matjaž 
Published: November 2023

Summary
Due to the severe and rapid corrosion of metallic equipment by strong acids at high temperatures, a high concentration of acidizing corrosion inhibitors (ACIs) is required during acidizing processes. There is always a need to develop more effective and environmentally friendly ACIs than current products. In this work, a highly effective ACI obtained from a novel main component and its synergistic effect with paraformaldehyde (PFA) and potassium iodide (KI) is presented. The ACI was prepared from the crude product of benzyl quinolinium chloride derivative (BQD) synthesized from benzyl chloride and quinoline in a simple way. The new ACI formulation, named “synergistic indolizine derivative mixture” (SIDM), which consists of BQD, PFA, and KI, showed superior corrosion inhibition effectiveness (IE) and temperature stability compared with commercially available ACI. More importantly, the SIDM formulation eliminates the need for commonly used highly toxic synergists (e.g., propargyl alcohol and As2O3). In a 20 wt% hydrochloric acid (HCl) solution, the addition of 0.5 wt% SIDM mitigates the corrosion rate of N80 steel down to less than 0.00564 lbm·ft−2 at 194°F, while the corrosion rate at 320 °F is 0.0546 lbm·ft−2·when 4.0 wt% SIDM is added.

Published: November 2023

Abstract
Plant diseases, such as fungi and parasites, disrupt or alter the plant’s essential functions. In order to prevent potential economic losses from these plant diseases, early diagnosis of these diseases is crucial. The use of Deep Learning models for the detection and classification of plant diseases has been found to dramatically increase the speed of diagnosis while at the same time minimizing the amount of error involved. Taking advantage of a variety of tools and techniques, including transfer learning and ensemble learning, we have experimented with different deep-learning models and pre-existing architectures to find out which combination would best fit the data we gathered from the Sun Flower Fruits and Leaves dataset. Moreover, our best model has the ability to classify and detect sunflower disease with an accuracy of 97.91%, which is a considerable improvement over state-of-the-art models currently used for the classification and detection of sunflower disease.
Sustainable cement-based materials blended with recycled water treatment sludge and other various waste products as binder: Characterization and environmental-economical impacts
Authors: Kina Ceren 
Published: November 2023

Abstract
Water treatment sludge (WTS) is produced daily and disposed as hazardous material. It would be advisable to use locally available waste products as supplementary cementitious materials that ensures to be disposed of without harming the environment. As novelty, this research investigated the potential of using recycled-WTS with fly ash (FA) and ground-granulated blast furnace slag (BFS) as ternary blended binders. Thus, it can provide an economical solution and alleviate adverse environmental effects of excessive production of wastes and cement production. Within this scope, the mortars with 0–30 wt% replacement of cement with modified-WTS (MWTS) were produced as binary blend and also, they were combined with FA/BFS as ternary blended binders. Therefore, optimum utilization of waste products into mortar in terms of rheological, mechanical, durability, microstructural properties and environmental-economical aspects were examined. Adding 10% recycled-WTS as binary caused higher strengths with lower porosity measured by Mercury Intrusion Porosimeter test and denser microstructure, as revealed by XRD patterns and SEM results. However, the drawbacks of using recycled-WTS, in terms of rheological parameters and environmental-economical aspects, were suppressed by adding FA/BFS with comparable strength values. Specifically, cost, CO2 footprint and embodied energy were reduced by combining 10% MWTS with FA by 8.87%, 37.88% and 33.07%, respectively, while 90-day compressive and flexural strength were 5.1% and 5.32% lower. This study developed a feasible solution to use recycled-MWTS by obtaining more eco-friendly and cost-effective cement-based materials.
Comparison of Different Intervention Methods to Reduce the Incidence of Venous Thromboembolism: Study Protocol for a Cluster-Randomized, Crossover Trial
Authors: Tan Qin , Zhou Lu , Huang Weifeng , Lu Yihan 
Published: November 2023

Abstract
Background: Venous thromboembolism (VTE) remains a priority challenge among orthopedic trauma patients. It is crucial to further improve the prophylaxis against VTE in routine orthopedic treatment. This study aims to compare the efficacy of two low molecular weight heparin (LMWH) regimens and additional intermittent pneumatic compression in preventing VTE among orthopedic trauma patients.
Methods and analysis: This is a cluster-randomized crossover clinical study conducted in four hospitals in Shanghai from December 2019 to December 2023. The unit of randomization is orthopedic wards, and each ward will define a cluster. All clusters will implement four diverse intervention measures and one control measure in a given random sequence. Perioperative orthopedic trauma patients aged ≥18 years with stable vital signs, Caprini score＞2, and no contraindication of anticoagulation or intermittent pneumatic compression (IPC) device will be eligible. The sample size will be determined to be 2590, considering cluster effect, period effect, and interactions. We will generally use the intention-to-treat (ITT) at the subject level for each outcome. For the primary outcome of the study, the incidence of VTE will be presented as risk ratio and 95% CIs. Generalized estimating equation (GEE) will be deployed to compare differences and adjust cluster effect, period effect, and interaction among interventions and periods if applicable.
Discussion: VTE is a complication that cannot be underestimated after major orthopedic surgery. Early identification, early assessment, and early prevention can significantly reduce the incidence of VTE. Most guidelines recommend both medical and physical prevention, and we hope to demonstrate how they would affect the incidence among perioperative orthopedic patients. We want to explore if there is a difference between the two types of LWMH with or without an IPC device to provide more evidence for future guidelines and prevent more patients from the threat of VTE.
Ethics and dissemination: The study received approval from IRB of the coordinating center and all participating hospitals. Findings will be disseminated through peer-reviewed publications and conference presentations.

Experimental study on jet forming and penetrating process of parabolically shaped charge
Authors: Guo Yanchao , Peng Suping , Yang Renshu 
Published: November 2023

Abstract

In order to improve the jet velocity of the traditional conical shaped charge structure, a parabolic shaped charge structure is proposed by increasing the length of the busbar of the shaped charge. The results show that the metal jet formed by the explosion of parabolic shaped charge structure has stable flight performance and deep penetration depth. To this end, the static explosion tests of parabolic, cone and semi-circular shaped charge structures penetrating steel plates were carried out. Under the condition of the same charge and blast height, the explosion damage characteristics of three shaped charge structures on steel plate structures are compared. The perforation diameter of the parabolic and conical shaped energy structure is 20mm, and the perforation diameter of the semi-circular shaped charge structure is 19mm. The penetration depth of the parabolic shaped charge structure is 1.25 times and 1.5 times that of the cone and semi-circular structures, respectively. The results show that the parabolic shaped charge structure has a longer penetration depth than the traditional shaped charge structure.

Authors: Zhang Ke , Yan Zhenlei , Huang Zhitao 
Published: November 2023

Abstract

This paper takes the micro tilting-pad gas bearing as the research object. Based on the continuous model, first-order slip model, and Wu's new slip model， the static and dynamic Reynolds equations with the slip effect are established. First, a hybrid method integrating the Newton-Raphson iteration and finite difference methods was used to solve the static Reynolds equation. Then, the dynamic Reynolds equation was calculated by combining the partial derivative method with the equivalent coefficient method. So, the static and dynamic performance of the micro tilting-pad gas bearing can be obtained. The calculation results indicate that the bearing capacity and film pressure of the tilting-pad gas-bearing are reduced, and the dynamic stiffness is reduced after considering the slip effect. In the calculation results, the value of the continuous model is the largest, followed by the first-order slip model, Wu's new slip model is minimum. It provides a reference for the design of the micro tilting-pad gas bearing.
