Abstract

BACKGROUND
Insular epilepsy is a well-known cause of drug resistant epilepsy (DRE) in pediatric population. It can be a source of surgical epilepsy treatment failures when not ruled-out pre-operatively. Non-invasive methods often provide limited information about its existence, being the invasive methods necessary to diagnose it in the vast majority of cases. The most used is Stereo-Electroencephalography (SEEG). We report a series of DRE pediatric patients in which insular SEEG was performed to rule out insular epilepsy.
METHOD
We performed a retrospective review of pediatric DRE patients operated on SEEG including insular electrodes between April 2016 and September 2022. We described the different trajectories used (orthogonal or oblique) and surgical technique. After implantation, we assessed electrodes’ precision using three measures: entry point location error (EPLE), target point location error (TPLE) and target deviation (TD). We also reported complications occurred with this technique as well as diagnostic information provided.
RESULTS
Overall, 32 DRE patients were operated on SEEG including insular electrodes. 401 electrodes were implanted, 148 (39,91%) of whom were directed to the insula. 112 followed an orthogonal trajectory and 36 were oblique. The mean EPLE was 1,45 mm, TPLE was 1,88 mm and TD was 0,71 mm. Three patients suffered from frontal hematoma, two of them diagnosed on post-operative MRI and one who required surgery, with no sequelae. One patient suffered from meningitis treated with antibiotics with no permanent sequelae. Nine patients (28,13%) had the insula included in the epileptogenic zone.
CONCLUSIONS
Insular epilepsy has to be ruled-out in DRE patients when little suspicion is obtained after non-invasive testing. This is especially important in pediatric population, in which seizure semiology is more difficult to characterize and failures to control epilepsy have devastating consequences in neurocognitive development and scholarship. Given its relative low rate of relevant complications and potential benefits, we should consider widening the inclusion criteria for insular SEEG monitoring.
Generation of Random (Generalized) Orthogonal Matrices
Authors: Saraeb Ali 
Published: August 2024

Abstract

This paper presents an algorithmic method for generating random orthogonal matrices A that satisfy the property At S A = S, where S is a fixed real invertible symmetric or skew-symmetric matrix. This method is significant as it generalizes the procedures for generating orthogonal matrices that fix a general fixed symmetric or skew-symmetric bilinear form. These include orthogonal matrices that belong to groups such as the symplectic group, Lorentz group, Poincaré group, and more generally the indefinite orthogonal group, to name a few. These classes of matrices play crucial roles in diverse fields such as theoretical physics, where they are used to describe symmetries and conservation laws, as well as in computational geometry, numerical analysis, and number theory, where they are integral to the study of quadratic forms and modular forms. The implementation of our algorithms can be accomplished using standard linear algebra libraries.

Abstract

In the recent decade, Critical Discourse Analysis has received notable attention for exploring societal phenomena, yet a systematic scientific mapping of this field remains an area for improvement. This study employs Biblioshiny, a bibliometric analysis tool, to visually examine data and construct a comprehensive knowledge map of CDA research. The primary aim is to reveal the current status and trends of research in this field, identify key themes and emerging trends, and highlight valuable contributions. We scrutinized 10,031 articles related to CDA published between 2013 and 2023 from the Web of Science database. Significant findings show a recent surge in research, indicating an upward trend. The study identifies politics, media, and policy as popular themes. Notably, future research is anticipated to focus on populism, ideology, and metaphor, signifying a critical shift in emphasis. The study concludes that interdisciplinary approaches are poised to catalyze further growth in Critical Discourse Analysis studies, emphasizing the dynamic landscape and framework of this paramount global issue.
A Novel Hybrid Control Strategy to Implement Constant Current Output with ZVS for the double-side LCC Compensation Topology
Authors: Zhang Xuze , Li Jingang , Tong Xiangqian 
Published: August 2024

Abstract

To implement stable output current and zero-voltage switching(ZVS) with the minimum reactive current over a range of load and coupling coefficient for the double-sided LCC(DS-LCC) compensated inductive power transfer(IPT) system, a hybrid phase shift control and switched controllable capacitor(SCC) strategy is proposed in this paper. In the proposed control strategy, the output current can be regulated through the phase shift modulation, and the reactive current can be lowered by SCC. Most importantly, for the simplification and enhancement of the control system, the function between the phase shift angle and the SCC associated control angle is established, which means that two control variables can be regulated through a single close loop. Further, with the proposed hybrid control strategy, ZVS at the minimum reactive current can be realized over the range of the load and coupling coefficient, which means that efficiency at the low power can be enhanced. In order to validate the rightness and practicality of the proposed hybrid control strategy, a 120 W experimental prototype of the proposed DS-LCC compensated IPT system is constructed. The stable output current and ZVS with the minimum reactive current can be achieved over the coupling coefficient between 0.2 and 0.3, and the DC-DC maximum efficiency is 94.5%, proven by experimental results.

Abstract

Transmitting data via the Internet has always posed significant security threats. Before and after the epidemic, there have been reports of an increase in hacking and infiltration cases in proportion to the number of digital transactions. As a result, there is a greater need for secure financial transactions. This field of study suggests using chaotic sequences, complex keys, and bit shuffling in encryption algorithms as a secure method for encrypting and decrypting images in a software and hardware environment. In order to ensure that the encryption meets the requirements, this article employs a variety of approaches and performance evaluations, such as histogram analysis, correlation, NPCR, UACI, the NIST test, MAE, and entropy analysis. This article describes how to use an FPGA board with a novel chaotic map that is two-dimensional and initialised using complex bit and key shuffling to encrypt colour images for security enhancement.

Published: August 2024

Abstract

Background and AimsCombined acupuncture-drug anesthesia is an anesthesia modality that shows unique advantages in clinical surgical applications, as acupuncture and drugs work together to synergize the analgesic effect. The aim of this qualitative study was to qualitatively analyze patients' perceptions and experiences of perioperative acupuncture and combined acupuncture-drug anesthesia through interviews to provide ideas for future intervention development.MethodsWe conducted qualitative interviews with 20 patients using combined acupuncture-drug anesthesia at the surgical inpatients of Yueyang Hospital of Integrative Medicine, Shanghai University of Traditional Chinese Medicine, to understand the attitudes, feelings, and perceptions of surgical patients toward acupuncture with combined acupuncture-drug anesthesia before, during, and after surgery. We used to collect data using face-to-face, semi-structured, individualized in-depth interviews, and analyzed the interview data using Nvivo 12.0 software to summarize and refine the content from specifics to units and themes step by step.ResultsSurgical patients have positively evaluated combined acupuncture-drug anesthesia, despite having varying attitudes and perceptions about perioperative acupuncture. They reported feeling that the overall surgical experience with this method was safe and effective, with many experiencing positive responses during and after the procedure. The acceptance of acupuncture among patients was notably high, given its longstanding tradition and continued usage in China. However, the results also revealed certain areas that require improvement. Specifically, the preoperative education on combined acupuncture-drug anesthesia was found to be inadequate. Additionally, the potential benefits of preoperative acupuncture were not fully realized, and there was a lack of follow-up regarding acupuncture for postoperative responses. These findings suggest that there is still much room for improvement in various aspects of the perioperative acupuncture process.ConclusionsThe perioperative model associated with perioperative acupuncture in this study both gained patient acceptance and allowed the exposure of many deficiencies in scientific education about combined acupuncture-drug anesthesia and follow-up of perioperative acupuncture. We accordingly propose a process for perioperative acupuncture in the hope that it will provide ideas for combined acupuncture-drug anesthesia with perioperative acupuncture in the future.

Abstract

Background
Phalangeal fractures, especially those of the proximal phalanx, account for approximately 25% of hand and wrist fractures. Plating is generally associated with severe tendon-related complications and unsatisfactory hand function. Recently, volar plating has been used to fix intra-articular fractures at the base of the proximal phalanx, and it has been reported to result in excellent finger motion and grip strength. We proposed that volar plating has a lower risk of tendon irritation compared to dorsal plating due to the larger tendon-to-bone distances on the volar side. The purpose of this study was to: 1) present the surgical outcomes of 9 cases of extra-articular fractures in the proximal third of the proximal phalanx treated with volar plating, and 2) compare the tendon-to-bone distances between the volar and dorsal sides of the proximal phalanx.
Methods
A prospective cohort of nine patients with proximal third fractures of the proximal phalanx was recruited. Each patients underwent an MRI of the healthy middle finger on either hand to evaluate the distances between the flexor and extensor tendons and the proximal phalanx. The distances were measured using our in-built measurement tool. Demographics including age, gender, dominant hand, diabetes, smoking, affected fingers were collated. Complications such as extensor lag, wound infections, delayed wound healing, malunion, non-union, delayed union and tendon rupture were recorded. Total active motion (TAM) was also calculated by addition of ROM at the metacarpophalangeal joint, proximal interphalangeal joint and distal interphalangeal joint.
Results
Nine patients (6 males, 3 females) with fractures of the proximal third of the proximal phalanx were included in this study. All nine patients achieved good bone healing and recovery of functional range of motion (235 ± 24 degrees) after 1 year of follow-up. No major complications were reported, except for one patient with delayed wound healing. The measurements of the distances between the bone and the flexor and extensor tendons were reported as follows. There were significant differences in the average distance from the tendons to the bone cortex for the middle (volar: 1.07 cm, dorsal: 0.21 cm) and distal (volar: 2.96 cm, dorsal: 0.64 cm) third of the proximal phalanx (p = < 0.001).
Conclusions
The increased tendon-to-bone distance on the volar side may be an important factor contributing to the excellent hand function observed with volar plating in the treatment of proximal phalangeal extra-articular fractures

Abstract

Background
Although low-dose computed tomography (LDCT) screening effectively reduces LC mortality in high-risk individuals with a history of smoking in China, the feasibility and efficacy of lung cancer screening (LCS) in never-smokers versus smokers remains unclear.
Methods
We conducted a retrospectively opportunistic analysis at the National Cancer Center (NCC) in China from January 2006 to December 2022. A comprehensive LCS initiative was undertaken, involving 30,468 participants (54.5% male). Participants underwent LCS using LDCT. Potential malignancies were managed through joint consensus between patients and their physicians. Epidemiology, screening eligibility criteria, and LC detection rates and survival outcomes were compared between smokers and never-smokers.
Results
Among 30,468 participants, 339 LCs were pathologically confirmed in 289 patients. The LC detection rate was 0.9% overall, 0.8% in smokers (71/9,042), and 1.0% in never-smokers (218/21,426). In smokers, LC detection rates were 0.5% and 1.1% in the < 20 and ≥ 20 pack-year subgroups, respectively (P = 0.001). Early-stage LC (stage 0 or I) was detected in 73.8% of smokers and 78.8% of never-smokers, while advanced LC (stage III–IV) was found in 8.8% and 4.2%, respectively. Significant differences in histologic types were found between smokers and never-smokers (P = 0.01), although adenocarcinoma was the most prevalent in both groups, at 83.0% and 78.8%, respectively. The median nodule size was 9.9 mm (8.0–13.8) in smokers and 9.2 mm (6.8–13.6) in never-smokers (P = 0.228). Never-smokers tended to favour surgical treatment alone (88.0%) more than smokers (81.3%). The 10-year survival rate was higher in never-smokers (92.6%) than in smokers (88.8%). Only 15.6% of patients with LC met the United States Preventive Services Task Force (USPSTF) criteria for LDCT eligibility, while 29.1% met the China guideline for the screening and early detection of lung cancer (CGSL) criteria.
Conclusions
LDCT screening improves early LC detection and treatment outcomes for both smokers and never-smokers. Significant differences exist in epidemiology, histologic type, and survival between these groups. USPSTF and CGSL criteria overlook a significant number of LC cases, underscoring the need to relax smoking criteria and include never-smokers into the Chinese LCS programme.

Published: August 2024

Abstract

The optimal treatment strategy for acute ischemic stroke following cervical internal carotid artery occlusion of atherosclerotic lesions remains unclear. We retrospectively investigated the changes in imaging findings of the stenotic lesion after performing angioplasty alone. The most stenotic lesion on magnetic resonance angiography was significantly improved. No re-occlusion or stroke deterioration occurred in the perioperative period. Considering the risk of hemorrhagic complications at the acute phase, performing angioplasty alone may be useful. Additionally, the stenotic lesion can be evaluated using magnetic resonance angiography, with early consideration of additional treatment, if necessary.

Published: August 2024

Abstract

Background: The adverse effects of childhood trauma on the sense of meaning in life among middle school students have received widespread attention. Previous research has focused mainly on the direct connection between the two factors; however, little is known about the potential mediators of this relationship. To address this gap, the present study constructed a chain mediation model to examine whether social support and core self-evaluation mediate the association between childhood trauma and sense of meaning in life among middle school students.
Methods: A total of 2273 middle school students completed a self-report questionnaire about their childhood trauma, sense of meaning in life, social support, and core self-evaluation. The data were collected from students at 23 middle schools in South China. Statistical analysis was conducted via SPSS 27.0 and SPSS PROCESS.
Results: The results indicated that (1) the direct effect of childhood trauma on the sense of meaning in life among middle school students was significant, and (2) social support and core self-evaluation significantly mediated the relationship between childhood trauma and sense of meaning in life via three mediating pathways: the individual mediating role of social support, the individual mediating role of core self-evaluation, and the chain mediating roles of social support and core self-evaluation.
Conclusions: Our findings indicate that mitigating the negative impact of childhood trauma, increasing the strength of social support networks, and cultivating positive core self-evaluation may be key strategies for enhancing the sense of meaning in life among middle school students.
Incidence of herbivory of the invasive crab Percnon gibbesi on the endemic Mediterranean seagrass Posidonia oceanica
Authors: Puentes Daniel , Anton Andrea 
Published: August 2024

Abstract

Seagrasses are one of the most productive marine ecosystems in the world. Posidonia oceanica, an endemic Mediterranean seagrass, is under high and constant anthropogenic and natural pressure, including the introduction of invasive species and climate change. Percnon gibbesi, a small crab with a tropical and subtropical distribution, was first reported in the Mediterranean Sea in 1999, and today is established across the entire Mediterranean Basin, inhabiting the shallow rocky infra-littoral zone. Given that P. gibbesi and P. oceanica can co-occur in the same environments, an experiment was set up to study their plant-herbivore interaction. Using two experiments at two different temperatures (19°C and 25°C), the incidence of herbivory on the seagrass tissues (fruits, leaves, rhizome, and whole shoot) by the invasive crab was assessed. The fruits along with the rhizome were the most consumed tissues, and the leaves of P. oceanica were the least consumed, which could be a consequence of tissue structure characteristics and/or nutrient quality. The incidence of herbivory on the leaves of P. oceanica was not affected by temperature. The herbivory pressure of the exotic crab P. gibbesi on native seagrass P. oceanica will likely be limited to a shallow bathymetric range, but given the large scale of the invasion, the consumption of P. oceanica could become a relevant ecological issue in the area.

Abstract

Haemolytic anaemia, though uncommon, may occur in pregnancy. A rarer variant, Idiopathic haemolytic anaemia or Coomb-negative haemolytic anaemia has been described. This causes haemolysis during pregnancy and spontaneously resolves after delivery, only to recur during subsequent pregnancies, with the woman being entirely symptom-free during her non gravid state.
We encountered a clinical scenario that typifies this rare clinical presentation in a 31-year-old unbooked G5P3+1 (2A) +1 perinatal mortality referred from a private hospital at an estimated gestational age of 32 weeks +4 days.
Her clinical history and investigations were suggestive of idiopathic haemolytic anaemia of pregnancy.
She was managed with haematinics, had 4 units of blood transfused, and was commenced on glucocorticoids. She was then counseled for and had a scheduled caesarean section at EGA of 34 weeks +0D on account of concomitant fetal malpresentation and was delivered of a live male neonate with no signs of jaundice. The patient recovered with dramatic resolution of the yellowness of the eyes postpartum and was discharged on postoperative day 5 with normal indices and was discharged alongside her baby in stable condition.
The rare incidence of this clinical presentation and a favourable fetal and maternal outcome, in this case, merits its presentation.

Published: August 2024

Abstract

The evolution of point bars along the Niger River in the Niger Delta, Nigeria, from 1974 to 2024 using remote sensing and machine learning. The dataset includes DEM and Landsat series satellite imagery, supplemented by Sentinel-2 data for high-resolution analysis from USGS. Rainfall data from 1983 to 2023 was sourced from the Center for Hydrometeorology and Remote Sensing. Object-Based Image Analysis (OBIA) identified and mapped point bars. Support Vector Machines automated classification, ensuring accuracy through precision and recall metrics. ArcGIS 10.5 tracked changes over time, revealing significant fluctuations in river area and point bar dimensions. River area fluctuated significantly, decreasing from 46,376.54 km² in 1974 to 42,711.05 km² in 1984, rising to 49,601.2 km² in 2014, and falling to 44,796.47 km² in 2024. Contrarily, the total point bar area increased dramatically from 1,945.63 km² in 1974 to a peak of 7,026.33 km² in 2004, followed by a decline to 8,087.89 km² in 2024. This trend indicates complex interactions between sediment deposition, erosion, and river flow patterns. Notably, the maximum point bar area peaked in 1994 at 2,273.85 km², then fell to 783.84 km² in 2024, while the mean point bar area showed a general decrease over the study period. Spatial autocorrelation analysis revealed significant clustering of point bars and elevation (Global Moran’s Index = 1.059738), and a strong positive relationship between point bars and rainfall (R² = 0.9921). These findings align with global trends, underscoring the impact of climatic fluctuations and human activities on river morphology and sediment dynamics.
