Abstract
Real-Time monitoring surface casing vent flow (SCVF) and enhancing its efficiency through accurate disturbance profiling has traditionally relied dominantly on acoustic logging tools and data. However, with the rise of distributed sensing technology over the past decade, the use of distributed fiber optic sensing (DFOS) for quantitative disturbance profiling has gained significant traction. This technology allows for acquiring high-resolution acoustic data along the wellbore, offering detailed insights into the acoustic signatures linked to potential gas leaks. This work presents an integrated workflow for analyzing distributed acoustic signals, supported by two real world case studies. The application of distributed acoustic sensing (DAS) technology for gas leak detection has the potential to greatly improve the accuracy and reliability of well integrity monitoring.
The developed solution enhances our qualitative disturbance profiling software by providing a quantitative assessment of intervals more prone to gas leakage. During development, we utilized two supercomputers to efficiently process large-scale DAS data and apply multiple algorithms to extract key features related to gas leakage. To quantify the DAS responses, we created an algorithm that extracts frequency-domain information, enabling spectral analysis to compare DAS signals across different frequency ranges. By aggregating waterfall plots generated from raw phase data, we were able to identify potential gas leak zones.
Our solution was applied in a blind test to two abandoned wells with gas leakage, as identified by the operator's analysis. Potential gas leak intervals were detected in Well #1 and Well #2, all of which were subsequently confirmed by the operator. The integration of DFOS technologies represented a significant advancement in well monitoring and management, offering continuous, high-resolution data while addressing the limitations of traditional methods. The final version of the developed software is optimized for conventional computers. It can efficiently read HDF5 files, reduce the large DAS data size by a factor of 100, and provide real-time visualization. To enhance security, the analysis results are encrypted before being stored in the cloud, ensuring secure remote access for operators to monitor gas leaks and other well activities seamlessly.
The novelty of this work lies in the real-time, cloud-based monitoring of SCVF using DAS technology in oil and gas wells, offering quantitative insights into the monitoring process. Real-world case studies demonstrate substantial improvements in SCVF monitoring through the proposed approach. These advancements will enable the industry to improve decision-making strategies related to the integrity and management of abandoned wells.
Optimizing Ultra Heavy Oil Recovery by Enhancing Steam Injection Conformance Using Autonomous Outflow Control Devices
Authors: Moradi Mojtaba , Chanaga Arlen , Konopczynski Michael 
Published: December 2024

Abstract
Ultra-heavy oil recovery presents unique challenges due to the oil's high viscosity and the limitations of traditional steam injection methods, particularly in ensuring efficient steam distribution. Steam-Assisted Gravity Drainage (SAGD) is a widely used technique; however, its effectiveness is often reduced by uneven steam conformance and high steam-oil ratios (SOR). This research introduces a novel application of Autonomous Outflow Control Devices (AOCDs and OCDs) to address these challenges. Unlike conventional passive devices (OCDs), AOCDs dynamically adjust steam flow rates in real-time based on reservoir conditions, ensuring more uniform steam distribution and reducing heat loss.
Using advanced dynamic reservoir simulation and wellbore modeling software, this study evaluates the performance of AOCDs in improving steam injection conformance and enhancing oil recovery. The results show a 15% increase in oil recovery and a 10% reduction in SOR, demonstrating the effectiveness of AOCDs in optimizing thermal efficiency. These findings offer valuable insights for improving SAGD operations, providing a more sustainable and cost-effective solution for ultra-heavy oil reservoirs.

Abstract

This study evaluates the contrast in the concentration of seven metallic elements (As, Cd, Cr, Cu, Hg, Mn, and Pb) in tissues (G, gonads; H, hepatopancreas; and M, musculature) of the ghost shrimp Callichirus corruptus, as a response to sediment contamination in two sandy beaches in Southern Brazil with different anthropogenic status (JUR, Juréia; and STS, Santos). The biotic and abiotic samples were collected with a suction pump, and subjected to metal quantification by Atomic Absorption Spectrophotometry technique. Statistical analyses were performed in R-Studio. In JUR, the sediment had Cr, Cu, and Mn concentrations two times lower when compared to STS (t ≤ 7.80; p ≤ 0.01), while STS had Hg concentrations between the Interim Sediment Quality Guideline (ISQG) and Probable Effect Level (PEL) parameters. Three metals (Cd, Cr, and Cu) presented concentrations above the Maximum Tolerated Limit indicated by the Brazilian Health Regulatory Agency (Anvisa), with prawn bioaccumulation up to eight times greater in STS than JUR (t ≥ 4.42; p ≤ 0.03). Therefore, this study confirms higher metal concentrations in the biotic and abiotic compartments of Santos, which has a high human population density and a significant industrial and port complex, in contrast to Juréia, which is located in an extremely preserved ecological station. Furthermore, the research presents novel information on trace elements in the sandy sediments of the studied sites. Additionally, it provides unprecedented evidence on metal concentration for C. corruptus, which can be used in monitoring programs for sandy beaches due to its metal bioaccumulation potential.

Abstract

Background: Pelvic congestion syndrome (PCS) refers to non-cyclical, persistent pelvic pain that lasts longer than six months and is primarily felt by women during the childbearing years. Trans-catheter ovarian vein embolization is now thought to be the 1st line of therapy for pelvic congestion syndrome. The goal of this research was to evaluate the role of trans-catheter gonadal vein embolization in treatment of pelvic venous disorder in females having Symptomatic PCS. We chose the sclerosant foam (Lauromacrogol 3%) as an embolic material to assess its efficacy in management of PCS as the cost of other embolic materials including embolization plugs, coils and glue is very high to our populations in Egypt.
Methods: This prospective cohort research has been performed on fifty female cases (with mean age 30.7 years) with CPP persistent for over six months poorly responsive to medical treatment. All cases have been referred to the IR unit for gonadal veins embolization. We chose Sclerosant foam (Lauromacrogol 3%) as an embolic material then the patients underwent 6-month monitoring duration to evaluate the outcomes and recurrence rates using VAS and transvaginal ultrasound.
Results: VAS declined dramatically from 8.8±1.2 (mean +/- SD) pre-procedure to 1.8±1.4 (mean +/- SD) post-procedure (highly significant P value <0.001). The technical success rate of pelvic vein embolization was 100%; the clinical success has been determined by the TVUS, which demonstrated either complete resolution of the pelvic varices or static varices, and the VAS, which demonstrated a marked improvement.
Conclusions: The management of pelvic congestion syndrome through gonadal vein embolization using Sclerosant foam (Lauromacrogol 3%) is an effective and safe procedure with 100% technical success rate and dramatic improvement of pelvic pain and varices. Moreover it is a cost effective procedure.

Abstract

Sign language serves as a crucial means of communication for the deaf and mute community, facilitating their integration intosociety. There exist many sign languages in the world like ASL, ISL etc. in which much research have already been done. Thispaper represents the first effort to create a dataset for Mizo sign language, as no previous dataset exists for this low resourcelanguage. The work have been carried out by capturing hand gestures using high-quality camera Kinect V2. The differenthand gestures are captured on a different time periods such as morning, afternoon, evening and night time to capture therealistic scenarios faced by the deaf and dumb community. This dataset consists of 25 different sign alphabets with differenthand gestures for each alphabet in the Mizo languages. The original captured hand gestures in the dataset occupy a size of 3GB, the original data are resized to further enhance the computational time and better utilizes computational resources. Theresized data are then the fed through novel normalization technique to expand the dataset which results in a final dataset witha size of 10 GB. The uniqueness of our contribution lies in filling this gap by capturing and annotating sign language gesturesspecific to the Mizo language, which has not been documented in digital or structured formats before. This foundational step iscritical as it lays the groundwork for future research and development in sign language recognition for Mizo speakers.

Abstract

The COVID-19 pandemic caused by SARS-CoV-2 has had a significant impact on global social and economic activities. The continuous emergence of new SARS-CoV-2 variants has made the global pandemic of COVID-19 difficult to predict. Therefore, it is of great significance to closely monitor the SARS-CoV-2 epidemic and understand the evolution and transmission characteristics of SARS-CoV-2. In this study, we reported 36 SARS-CoV-2 infected cases in Wuhan in June 2023. Genomic surveillance revealed that this outbreak was caused by Omicron XBB variants, among which FY.3 and its descendants FY.3.1 and FY.3.2 dominated, this trend was consistent with the prevalence of SARS-CoV-2 nationwide in June and July. Analysis of mutations within hosts and between populations suggested that the S and ORF8 genes undergone positive selective pressure, which may due to their important roles in host adaptation. These findings may provide insights into predicting the evolutionary direction of SARS-CoV-2 in terms of variant competition, developing multipart vaccines, and supporting the evaluation and adjustment of surveillance, prevention, and control strategies in the Wuhan region.

Abstract

Background
The aim of this study is to evaluate the quality and reliability of Turkish and English YouTube video contents regarding the treatment of gingival recession.
Material Methods:
The terms "gingival recession treatment", "receding gum treatment", and "gingival recession surgery" were searched on the YouTube video platform using Turkish and English. 42 Turkish and 67 English videos that met the inclusion criteria were evaluated. Video title, origin, content type, duration, upload date, number of views, number of likes/dislikes, viewing rate and interaction index of the videos were recorded. The Global Quality Scale (GQS) and the DISCERN tool were used to evaluate the quality and reliability of the videos.
Results
In the study, the reliability scores of Turkish and English videos were found to be 2 and 3, respectively, according to DISCERN criteria. Both the content evaluation score and reliability scores of Turkish videos were found to be lower than those of English videos. The majority of Turkish videos were scored as GQS 1, while the majority of English videos were scored as GQS 2. 97% of both Turkish and English videos had low quality content.
Conclusion
In this study, we found that 97% of the evaluated videos had low quality content. In order to prevent the spread of misinformation and to ensure that patients can access accurate information, it would be beneficial for educational institutions and specialist to prepare interesting videos with comprehensive content that are easy to understand for patients and share them on internet platforms such as YouTube.

Published: December 2024

Abstract

Purpose
The prevalence and phenotype of capillaroscopic abnormalities in patients with autonomic nervous system dysfunction has not been investigated. Multiorgan involvement in dysautonomia entails abnormal vasoreactivity. We aim to corelate the diagnosis of autonomic dysfunction with certain clinical manifestations that may provide prognostic or diagnostic information using a noninvasive technique: nailfold video capillaroscopy (NVC).
Methods
Patients with autonomic nervous system dysfunction were recruited from rheumatology and neurology clinic with voluntary NVC procedure from 1/31/24 to 10/1/24 and a comparison with normal controls was done. Additional information recorded includes demographics, diagnosis of type of autonomic dysfunction with autonomic testing including but not limited to reflex screen, sweat test, Valsalva maneuver, nerve fiber density, electromyography (EMG), serology, history of autoimmune disease. NVC was performed on a total of 27 patients. The study was approved by the Mayo Clinic Institutional Review Board.
Results
Autonomic dysfunction group consisted of small fiber neuropathy (37%), orthostatic hypotension (48%), autonomic neuropathy (30%), limited autonomic neuropathy (7%), POTS (7%) and connective tissue disease (7%) amongst other types. Patient with autonomic dysfunction had statistically significant increased microhemorrhages, dilated capillaries and ramifications compared to controls. There was statistically significant correlation of age with capillary ramifications and BMI with capillary density and dilated capillaries.
Conclusion
Autonomic dysfunction was associated with statistically significant microvascular abnormalities compared to normal controls with a distinct NVC pattern. There was statistically significant correlation of age and BMI with microvascular abnormalities. We demonstrate diagnostic potential of NVC in autonomic dysfunction and advocate for further study of capillary structure in autonomic dysfunction.

Published: December 2024

Abstract

Background
This study sought to uncover potential risk factors linked to disease development by analyzing the medical and renal histology features of individuals with idiopathic membranous nephropathy associated with nephrotic syndrome.
Methods
Our retrospective research involved 373 patients who met the specified inclusion criteria and had a kidney biopsy diagnosis between January 2016 and August 2023. The crowds recorded the clinical and pathological characteristics at baseline and assessed the outcomes during the follow-up period. Researchers used a binary logistic regression analysis to identify the risk factors associated with disease progression in individuals with membranous nephropathy. We categorized the patients into two distinct groups: those with progressing renal disease and those without.
Results
Thirty-six (9.65%) people experienced nephropathy progression following an average follow-up period of 15 (inter-quartile range 9,24) months. Serum total cholesterol levels had a substantial negative connection with albumin, as evidenced by Spearman's rho = -0.39 (p < 0.001). The ROC curve for serum total cholesterol indicated a sensitivity of 69.4% and a specificity of 76.9% in predicting nephropathy development. The area beneath the curve was 0.789 (p < 0.001, 95% CI: 0.725–0.852). Logistic multivariate analysis revealed that total cholesterol levels in the blood (OR = 1.554, 95% CI: 1.294–1.861, p < 0.001) constitute an independent risk factor for nephropathy development.
Conclusion
In patients with membranous nephropathy and nephrotic syndrome, serum total cholesterol levels act as a separate danger indicator for disease advancement.

Authors: Zhu Yupeng , Shi Weili , Xu Jun , Wang Qizheng , Zeng Shan , Zhu Songyue , Zhang Songlin , Yang Yuping , Lang Ning 
Published: December 2024

Abstract

Background
Lateral patellofemoral compression syndrome (LPCS) is a condition characterized by increased lateral patellofemoral joint pressure caused by long-standing lateral patella tilt, adaptive lateral retinaculum tightening, and an imbalance in stress between the lateral and medial femoral condyles. Diagnosis of LPCS is challenging because of its complex and diverse etiology and pain mechanisms, thus we lack objective diagnostic criteria.
Purpose
This study aimed to explore the feasibility of various structural measurement parameters of MRI of the knee to diagnose LPCS and to identify new MRI diagnostic indicators to as references and guidance for LPCS clinical diagnosis.
Methods
This study enrolled 168 patients, who were divided into three groups: The LPCS group, the simple osteoarthritis (SO) group, and the normal control group (n = 56 participants per group). Diagnosis of all patients was carried out at the Department of Sports Medicine, Peking University Third Hospital. A standardized MR scanning protocol was used, including sagittal and coronal fat-suppressed proton density-weighted imaging and sagittal T1-weighted imaging. Two radiologists used the picture archiving and communication system to analyze the MR images and measure the patellarpatellar tibial angle (P-PTA), the quadriceps-patellar angle (Q-PA), the patellar length (LP), the patellar tendon length (LT), the LP/LT ratio, and the Insall-Salvati ratio (ISR).
Results
The LPCS group had significantly lower P-PTA and LP values, but higher LT and ISR values, compared with those in the normal and SO groups (all P < 0.05). Compared with that in the normal group, the LPCS groups' Q-PA value was higher (P = 0.034). According to receiver operating characteristic analysis, the optimal cut-off values for PPTA, LP, LP/LT, and ISR were 146.45°, 41.10mm, 0.85, and 1.19, with sensitivities and specificities of 67.86%/59.82%, 78.57%/55.36%, 67.86%/58.93%, and 66.07%/60.71%, respectively.
Conclusion
Measurement parameters of MRI, particularly P-PTA and ISR, can serve as important tools to assist in the diagnosis of LPCS. Assessment of these parameters should be included in the clinical diagnostic process for LPCS to improve diagnostic accuracy.
Persistence of fluoxetine, escitalopram, and sertraline for depression in children and adolescents: a nationwide population-based study in South Korea
Authors: Lee Dong Yun , Cha SangHun , Park Rae-Wong , Jeon Soo Min 
Published: December 2024

Abstract

Background
This study aimed to evaluate persistence and treatment changes of three widely used selective serotonin reuptake inhibitors (SSRIs)—fluoxetine, escitalopram, and sertraline—in children and adolescents with depression.
Methods
We conducted a nationwide population-based retrospective cohort study using the Health Insurance Review and Assessment Service database of South Korea (2007–2019). Children and adolescents aged 5–19 years who were newly prescribed fluoxetine, escitalopram, or sertraline for depression between 2009 and 2018 were enrolled. Over a one-year follow-up period, we estimated treatment persistence and examined four treatment changes: simple discontinuation, switching, augmentation, and initiation of antipsychotics. Adjusted hazard ratios and 95% confidence intervals were estimated using Cox proportional hazards models, adjusting potential confounders.
Results
Only approximately 3% of patients remained on their SSRI after one year. Most treatment changes occurred through simple discontinuation, followed by switching, initiation of antipsychotics, and augmentation. Fluoxetine had the lowest risk of treatment change, with the lower risk of augmentation and initiation of antipsychotics compared to escitalopram and sertraline. In contrast, escitalopram had lower switching rates, while sertraline was associated with a lower risk of simple discontinuation. Sociodemographic factors and comorbidities significantly influenced treatment changes.
Conclusions
While each SSRI exhibited distinct patterns in treatment changes, none consistently outperformed the others, underscoring the importance of individualized SSRI selection based on patient-specific factors. These findings highlight the need for tailored treatment approaches when selecting SSRIs for pediatric and adolescent patients with depression.

Published: December 2024

Abstract

Nonattendance at women’s health physiotherapy sessions involves considerable cost in time and resources. Uncovering factors associated with nonattendance is one priority, and the current research aimed to enhance understanding of this issue. In each of two studies, women referred for women’s health physiotherapy were interviewed. Study 1 (N = 80) compared patients who did and did not attend their appointment, and Study 2 (N = 61) compared reasons for nonattendance given by women with pelvic-floor muscle dysfunction and pelvic girdle pain. The results corroborated several key issues associated with nonattendance noted in previous reports, such as problems in the administration of appointments. Results further suggested attention to the information given by healthcare professionals at the time of referral may help remove some barriers to attendance. The issue of transport to appointments was raised, and developing links to affordable and reliable systems is critical, including development of dedicated transport systems. Finally, the psychological of patients who do not attend appeared to differ and addressing these issues could form part of their treatment. Although each recommendation does involve cost, the savings from reduction in nonattendance may well far outweigh any initial costs of set up.
