Authors: Febriani Gani , Sari Ika Mustika , Suyana Iyon
Published: February 2025

Rapid advancements in science and technology have made critical thinking skills increasingly essential. 21st-century education focuses not only on knowledge transfer but also on developing crucial skills to meet future challenges. This study examines the enhancement of students' critical thinking skills by implementing the Learning cycle of the 9E model, which integrates real and virtual practicums on dynamic fluid materials. The research used a pre-experimental design with a pretest-posttest approach involving 27 grade XI students selected via purposive sampling. Data were collected using a critical thinking skills test with 19 two-level multiple-choice questions and analyzed with Rasch modeling techniques. Results showed that the Learning cycle of the 9E model, combining real and virtual practicums, improved students' critical thinking skills by 5.74 logits, indicating a medium level of improvement. The racking technique revealed that initially, difficult questions became easier post-intervention, highlighting a positive impact on learning. Thus, the Learning cycle of the 9E model with real-virtual practicums effectively enhances students' critical thinking skills in dynamic fluid materials. These findings have significant theoretical and practical implications, supporting classroom learning and educational policies. The stacking and racking techniques provide deeper and more accurate analysis results.

Seeing the Unseen: Computer Vision in Action
Authors: Pallanich Jennifer
Published: February 2025

_

Technology that can analyze visual data with unprecedented speed and accuracy is emerging as a powerful and potentially transformational tool for the industry.

Artificial intelligence (AI), machine learning, and computer vision are a trio of technologies that, when combined, make it possible to interpret images and videos to identity patterns that can be used in many ways.

Assessing Hole Cleaning

A 3-month proof of concept trial has shown computer vision can assess the quality of hole cleaning during well construction, although some details need to be refined before the technique can be widely deployed.

SPE 220985 describes assessing the effectiveness of hole cleaning at five Permian Basin wells by using an image analysis model combined with a remotely monitored and autonomous camera system to measure the recovery rate of drilled cuttings.

During a session at SPE’s 2024 Annual Technical Conference and Exhibition in September, Shekhar V. Gosavi, principal borehole management engineer at ExxonMobil, said that as of the time of writing the paper, most of the quantitative measures of hole cleaning using the traditional approach were still in the “art” phase with the accuracy of measurements varying by plus or minus 20%.

“That’s not acceptable,” he said.

But the proof of concept did indicate that an optical camera can, under the right conditions, measure the volume of cuttings returned to the shaker (Fig. 1), he said. Once refined, real-time cuttings-returns analysis using computer vision could enable increased drilling speed and lower risks.

According to the paper, the “technology has the potential to significantly reduce the nonproductive time associated with circulating and mitigating packoff events, effectively addressing inadequacies in current cuttings-transport modeling and hole-cleaning practices.”

Prior to the trials, the vendor, DrillDocs, worked with a team at The University of Tulsa Drilling Research Projects to validate the image analysis model against a cuttings-transport model developed at the university. DrillDocs engaged BlackHawk Datacom to provide technical support during mobilization, ensuring that the system was installed by experienced personnel with minimal impact on active drilling operations.

To conduct the trials, ExxonMobil installed an explosion-proof optical camera with onboard image analysis software near the shale shaker, turning the shaker into a source of digital information.

Other elements included network infrastructure and a server for data processing, storage, and visualization. The camera (Fig. 2) monitored and analyzed about 500 bbl of drill cuttings returned to the shaker from drilling 6.75-in. lateral hole sections in the Wolfcamp formation.
Vaca Muerta Shale Drives Argentina’s LNG Export Ambitions
Authors: Szymczak Pat Davis
Published: February 2025

_

Shell’s entry into a project development agreement (PDA) with Argentina’s state-owned oil and gas producer YPF to initiate Phase 1 of the Argentina LNG export facility may have just reset the debate over whether Buenos Aires can reap the benefits hidden in its vast shale reserves.

The facility proposed for construction at Sierra Grande, Río Negro, on Argentina’s Atlantic coast, is intended to use dedicated blocks in the Vaca Muerta shale formation in western Neuquén Province whose gas reserves rank as the second-largest technically recoverable shale gas resources globally. The US Energy Information Administration estimates 308 Tcf, located in approximately 30,000 km2.

The PDA to jump-start the $50 billion Argentina LNG project obligates Shell and YPF to collaborate on pre-front-end engineering and design (FEED) activities until a decision is taken on FEED, YPF said in a press statement in late December 2024.

Phase 1 envisions deployment of two FLNG units with a combined production capacity of 10 mtpa. Construction of onshore facilities would follow in Phase 2 and 3, raising total capacity to 30 mtpa with gas reaching the liquefaction facility via 580 km of dedicated pipelines, YPF said.

Tax Breaks Lure Investments

But Argentina LNG isn’t alone. Two other LNG liquefaction and export options are also now under study as Argentina seeks energy independence and a piece of global LNG revenues in the 2030s and beyond with projects driven by Buenos Aries’ new Basis Law which incentivizes investments to construct pipelines and export terminals associated with Vaca Muerta.

Projects exceeding $200 million are guaranteed 30 years of legal and regulatory stability if 40% of the investment is made within the first 2 years; projects over $1 billion are eligible for tax breaks including export and import tax exemptions.

The LNG initiatives now competing with Argentina LNG include

- The Southern Energy FLNG facility championed by 50% BP-owned Pan American Energy, YPF, and shipping company Golar LNG would utilize the Golar Hilli vessel with a capacity of 2.45 mtpa. Independent energy company Pampa Energía recently took a 20% stake to make a foursome in the partnership.

- A bid by Tecpetrol, the oil arm of Argentina’s TechintGroup, expects to complete FEED by mid-2025 on a proposed onshore, 4-mtpa modular plant, expandable to 20 mtpa, according to Argentina’s EconoJournal. Though a location has yet to be announced, Tecpetrol is reportedly favoring Bahía Blanca and an industrial park concept so infrastructure such as pipelines and port access can be shared with other companies.

EconoJournal reported that Tecpetrol’s project could be integrated with a competitor and for Tecpetrol, its LNG exports would be complemented with gas shipments to Brazil. In August 2024, the government preauthorized Tecpetrol and TotalEnergies to export gas to Brazil whose state-owned oil and gas producer Petrobras still holds a 34% stake in the Rio Neuquén shale gas field in a venture with YPF and Pampa Energía.

Fatigue-induced failure is recognized as the primary cause of tubular twistoff. Repeated cyclic bending loads and stress caused by dogleg severity, pipe weight, and buckled drillpipes can result in drillstring fatigue and failure. The complete paper deals with the incidence of seven twistoff accidents in large shallow-dogleg sections in three deep wells with a true vertical depth (TVD) of greater than 5000 m. The authors propose a methodology for preventing drillstring fatigue and failure in deep wells with large shallow doglegs.

Introduction

Three deep exploration wells with TVD of greater than 5000 m have suffered from repeated (two or more) twistoff incidents in large shallow-dogleg sections while drilling. All drillstrings used for exploration wells were newly manufactured and evaluated to be flawless by ultrasonic testing and magnetic particle inspection before entering the wellbore. The cumulative working time of this patch of drillstring was expected to be between 900 and 1,000 hours before maintenance; however, total working hours for each failure case were far from the preset limit.

Enormous time and financial loss were incurred during fishing jobs after these drillstring failures. Moreover, secondary downhole accidents, including stuck pipe, also were encountered during fishing jobs. Well B was sidetracked at approximately 5900 m after 11 unsuccessful fishing jobs and large, deep doglegs were created during sidetracking, which greatly affect wellbore integrity and increase the difficulty for later well-completion operations. Under such circumstances, plugback and redrilling with better trajectory-dogleg control may be an alternative, but this solution generally comes with huge financial cost. Prevention of drillstring failure is crucial for successfully reaching target depth if drilling is to be continued.

The relative fatigue index-prediction model, used to calculate the cumulative fatigue distribution of the entire drillstring in drilled or predrill intervals, is established by considering drillstring-stress characteristics and crack-propagation behavior. A section of the complete paper is devoted to a discussion of principles behind these considerations, including related equations.

Procedures and Workflows

Drillstring-Fatigue and -Failure Prevention.

In general, deep or ultradeep wells have wellbore structure designs of three or more casing layers. The drillstring may be reused in different well spuds or sections in actual drilling operations. Therefore, the actual usage record of the drillstring shall be considered when calculating the cumulative fatigue index of the drillstring in predrill intervals.

Shale oil and gas are among the more strategic oil and gas replacement resources in China. The second and third members of the Paleogene Liushagang Formation in the western South China Sea are primary source rocks featuring multiple mature laminated shale and sand oil reservoirs. The authors applied a shale-oil-evaluation method based on sandstone wireline-formation-testing (WFT) data.

Introduction

Weizhou shale oil in the Beibu Gulf of the South China Sea regionally occurs in a large fault block formed by the northeast- and northwest-trending faults, including the east, middle, and west blocks. From bottom to top, it is developed with the Liu 3 member early-stage and late-stage laminated shale-oil reservoir of the upper-sequence lake intrusion, and the Liu 2 member early-stage sandwich-type shale oil, the middle-stage laminated shale oil, and the late-stage matrix shale oil of the lower-sequence lake intrusion. The early- and late-stage laminated shale oil of the Liu 3 member of the upper-sequence lake intrusion is developed mainly from a thin sheet sand in the fan delta front. The early-stage sandwich-type shale oil of the Liu 2 member of the upper-sequence lake intrusion is developed mainly from a turbidite sheet sand, while the middle-stage laminated shale oil is developed mainly from turbiditic laminated sand. In 2022, the first pilot well of offshore shale oil in this block was drilled and commercial oil flow was obtained, indicating that this area contained good shale-oil resources and the material foundation for developing large- and medium-sized shale-oil fields.

WFT Data

All WFTs described in this paper were performed with a modular formation dynamics tester. Representing a new generation of WFT, the modular tester can be used for pressure measurement, mobility assessment, fluid identification, downhole fluid sampling, productivity prediction, and other logging operations. The WFT in shale-oil reservoirs always will show the formation as tight or dry, so the fluid composition, water production, and formation pressure cannot be obtained directly. In shale and sand laminated reservoirs, the sandstone and shale are in equilibrium; thus, their formation pressure and fluid properties are consistent.
Study Investigates Effects of Cyclic Salt Precipitation on CO2 Injectivity

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 219993, “Effects of Cyclic Salt Precipitation on CO2 Injectivity: From Pore Scale to Near Wellbore,” by Andrew Fogden, Till Bollermann, and Yennyfer Barreto, SPE, Wintershall Dea, et al. The paper has not been peer reviewed.

_

The rate and severity of potential loss of CO2 injectivity in saline aquifers as the result of brine dry-out and salt accumulation near the wellbore is one of the main uncertainties in carbon capture and storage project planning. Default parameters implemented in commercial reservoir simulators overestimate the degree of salt precipitation and the resulting permeability impairment. The current study used laboratory and digital core analyses of Berea sandstone to estimate the petrophysical and dynamic properties for adjustment of predicted precipitation and flow reduction in reservoir simulation models of intermittent CO2 injection with aquifer drive.

Introduction

Salt precipitation has multiple effects on CO2 flow, involving a complex interplay of physical and chemical mechanisms, dependent on length scale, time, and reservoir and injection history. The salt occludes pore volume to ultimately reduce absolute permeability, while formation brine dehydration initially increases the effective permeability to CO2 because of the increase of CO2 saturation. Precipitation is potentially more severe for intermittent injection. Backflow of “fresh” formation brine to the already-vaporized zone through aquifer drive and additional capillary suction created by the microporous and hydrophilic salt aggregates can lead to further salt accumulation.

The current study focuses on cyclic injectivity impairment caused by salt precipitation caused by formation water evaporation in contact with dry gaseous or supercritical CO2. The experimental procedure is inspired by work in the literature in which salt was precipitated in core plugs by oven drying and vapor evacuation, analyzed by mass-balance and gas-permeability measurements.

In this study, Berea sandstone plugs are used for brine infiltration/drying cyclic experiments and measurements of dried-state porosity and permeability, together with nondestructive X-ray imaging for correction of the effects of salt accumulation at plug boundaries. Analogous small-scale experiments and high-resolution imaging were performed on a Berea miniplug for pore-scale simulation of the effect of precipitated salt on porosity/permeability and two-phase flow properties of brine and CO2. Furthermore, these results were input to finite-difference simulations at plug- and reservoir-sector scales.

While the complete paper provides a detailed discussion of experimental results, including a series of figures and graphs, this synopsis concentrates on the experimental setup of the study and concludes with a summary of the authors’ findings. The synopsis also retains a discussion of the reservoir simulations used by the authors.
Role of Bryophytes in Phytoremediation: A Review
Authors: Singh Anushee , Choudhary Kiran
Published: February 2025

Bryophytes, including mosses, liverworts, and hornworts, are non-vascular plants that are increasingly recognized for their potential in environmental remediation, particularly in the field of phytoremediation. These plants possess unique biological characteristics, such as high surface-area-to-volume ratios, tolerance to diverse environmental conditions, and efficient absorption mechanisms, which enable them to accumulate or degrade various pollutants from air, water, and soil. Bryophytes have demonstrated significant potential in the remediation of heavy metals, organic contaminants, and radioactive substances, as well as in the restoration of ecosystems affected by pollution. This review explores the mechanisms by which bryophytes contribute to phytoremediation, including absorption, bioaccumulation, and the breakdown of contaminants, and examines their application in different environmental contexts. The article also addresses the challenges and future prospects of using bryophytes in phytoremediation practices, highlighting the need for further research to enhance their efficiency and applicability.

Published: February 2025

Background

SLE is distinguished by the development of multiple autoantibodies that lead to chronic inflammation and increased risk of cardiovascular diseases, especially atherosclerosis.

Objective

This examination sought to explore the association between the disease activity, clinical manifestations, and medication with the atherosclerotic lesion from SLE patients.

Methods

This inquiry investigated forty-two female SLE patients (18-45 years old) who met the 2019 EULAR/ACR assortment decency with matched healthy individuals as control A cross-sectional study was sanctioned at the Rheumatology Clinic of Saiful Anwar General Hospital Malang between July and November 2023. Demographic data, clinical manifestations, and medication history was documented in the medical records. Disease activity was stelled by the SLEDAI-2K score. Carotid Intima-Media Thickness (cIMT) and Flow-Mediated Dilation (FMD) (after brachial BP cuff inflation up to 200 mmHg for five minutes) examinations were used as atherosclerosis marker.

Results

Markedly higher of cIMT mean was demonstrated in SLE patients compared to healthy individual (0.51±0.11 vs 0.40±0.11 mm, p<0.001). FMD was subtancially curtailed in SLE patients set side to side to control (0.00 (0.00-0.10) vs 0.10 (0.00-0.28) mm, p=0.022). There was no statistical distinctness of the cIMT and FMD among SLE patients according to the presence of clinical manifestations. Neither cIMT nor FMD showed a statistically correlated with the disease activity. Patients who received hydroxychloroquine (0.57±0.02 vs. 0.50±0.09 mm, p=0.043) and cyclophosphamide (0.55±0.09 vs. 0.48 ± 0.10 mm, p=0.031) had higher cIMT. Higher cIMT was demonstrated in subjects who received steroid (p=0.045) and the dosage of steroid was essentially enforced to cIMT (R=0.418, p=0.034).

Conclusion

Authors: Pranata Fransiska Jaya , Notopuro Paulus Budiono , Hajat Arifatoel
Published: February 2025

INTRODUCTION: The DT100 offers both optical and mechanical modes, with its mechanical mode showing better homogenization than the STAGO, but comparative study is limited.

OBJECTIVES: The study aimed to evaluate the diagnostic accuracy of plasma Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) measurements using the DT100 and STAGO instruments.

METHODS: Designated as a cross-sectional study, this study was conducted at RSUD Dr. Soetomo from October 2022 to January 2023. Venous blood samples with plasma citrate anticoagulant 0.109 M 3.2% were consecutively collected from hospitalized patients, and all samples underwent testing using both the DT100 in mechanical mode (DT100, TCoag Ireland Limited, Ireland) and the STAGO employing an electromechanical method (Compact Max3, STAGO, France). Statistical analysis included comparison using Paired t-test, Pearson correlation, and Bland-Altman analysis to assess agreement between the results obtained from the two instruments.

RESULTS: The study included 51 patients. PT levels were significantly lower with the DT100 compared to STAGO (MD: -2.0; 95%CI: (-2.30) – (-1.3); p<0.0001), and showed a strong positive correlation between methods (r:0.9535; p<0.0001). However, Bland-Altman analysis for PT showed a bias of 1.84, with limits of agreement (3.30-0.37), indicating systematic differences and variability. APTT levels were significantly higher with DT100 compared to STAGO (MD:3.60; 95%CI: 2.13–5.07; p<0.0001), with a moderate positive correlation (r:0.6690; p<0.0001). For APTT, bias of Bland-Altman analysis was -3.60, with limits ((-9.84) – (2.64)), suggesting significant discrepancies and variability between methods.

CONCLUSION: The study found significant variability in PT and APTT measurements between the DT100 and STAGO methods.

Authors: Arisandi Jeffri , Lorensia Amelia , Rahem Abdul
Published: February 2025

BACKGROUND: Acute decompensated heart failure (ADHF) is a prevalent and complex condition that significantly burdens healthcare systems, requiring intensive care and leading to high treatment costs.

OBJECTIVES: This study aims to identify factors influencing cost discrepancies in hospitalized ADHF patients.

METHODS: This retrospective study was conducted at Universitas Brawijaya Hospital from July to August 2024. Data were collected from 86 ADHF patients who were hospitalized between January 2021 and December 2023. Information regarding the patients' clinical conditions, comorbidities, and medical procedures was extracted from their case histories. Statistical analyses included t-tests and Mann-Whitney tests.

RESULTS: In this study of 86 individuals with ADHF, 58.1% were over 65 years old, 31.4% were between 45 and 64 years old, and 10.5% were between 18 and 44 years old. By classification of care, 58.1% were admitted for Class 1 care, 30.2% for Class 2, and 11.6% for Class 3. Our findings indicated that the costs of treatment for patients with moderate and severe diseases were higher as compared to those of mild severity. Patients who had a length of stay over 7 days had higher costs than the ones whose length of stay was 1 to 3 days. Furthermore, Class 2 care was associated with higher costs than Class 3 care. The analysis also revealed that an increase in the number of comorbidities and medical procedures corresponded with higher treatment costs.

CONCLUSION: This study identified factors that increase the cost of treatment for patients with ADHF.

Evaluating the health-related quality of life in Egyptian cardiac patients using the brief version of the World Health Organization Quality-of-Life Scale (WHOQOL-BREF): observational cross-sectional study
Authors: Elbarbary Mohammed , Mousa Heba Safwat , Roshdy Walid , Alkassas Amr
Published: February 2025

Background: Health-Related Quality of Life (HR-QoL) reflects how a disease and its treatment may affect a person and serves as an important measure for assessing outcomes. This study aims to evaluate HR-QoL among Egyptian cardiac patients.

Methods: This observational cross-sectional study enrolled 400 participants, divided into group I for cardiac patients and group II for non-cardiac participants (control group). The HR-QoL was measured by applying the brief version of the World Health Organization quality of life questionnaire (WHOQOL-BREF).

Results: Compared to the control group, the physical and psychological domain scores for the cardiac patients were significantly lower (54.73 ± 21.59 vs. 63.89 ± 16.87, p = <0.001) and (41.72 ± 14.49 vs. 44.72 ± 12.69, p = <0.028), respectively. No statistically significant difference was found in the social and environmental domains.

Elderly, women, unmarried, and low-educated individuals had poorer scores. Ischaemic heart disease patients treated with percutaneous coronary intervention (PCI) had better overall health scores. Additionally, patients with ejection fraction (EF) between 31-40% showed the lowest scores in physical and psychological domains. The scores in all QoL domains were reduced in cardiac patients with superadded concurrent chronic diseases.

Conclusions: The WHOQOL-BREF scale is a crucial tool for assessing the quality of life (QoL) of cardiac patients, particularly in physical and psychological health. It is essential to conduct national and regional assessments, even in each country, to improve medical services and quality of life among cardiac patients.

Authors: Kaputrin Nur , Rizal Ardian , Karolina Wella , Widito Sasmojo
Published: February 2025

Background: Torsade de pointes (TdP) and ventricular fibrillation can cause rapid mortality. The etiological cause the ventricular arrhythmia must be detected and treated early, especially in the ER.

Objective: We report a patient with severe hypokalemia and TdP following the administration of Amiodarone in QT-interval prolongation

Case Report: A 32-year-old girl with diarrhea and vomiting for two days arrived to the ED with a seizure with her hand flexed and leg straight down. Her family reported she didn't take prescriptions regularly. She was GCS 224, hemodynamically stable, typical ECG showed extended QTc and her head CT was normal. During observation at the ED, she had seizure and the monitor revealed a Torsade de Pointes (TdP) ) with a pulse rate of 160-180 bpm. She was given Amiodarone and peroral Bisoprolol 5 mg. She returned to sinus rhythm with PVC bigeminy and was admitted to the ICU Laboratory data showed hypokalemia (1.9) improved (2.9) after treatment. Eight hours later, she experienced a TdP without pulse palpability for less than 1 minute, then Ventricular Fibrillation, began CPR, and the doctor in charge gave her a defibrillation operation once. She returned with sinus tachycardia 110-130 bpm. The next day, she was having recurring TdP episodes without a pulse. The doctor conducted CPR and defibrillation and returned with 120-130 bpm sinus tachycardia. The patient consulted a cardiologist and was prescribed lidocaine 1 mg/hour and continued Bisoprolol 5 mg for long QT problem. Observation The seizure ended 12 hours later, the patient was alert, GCS 456, and the ECG showed sinus rhythm with extended QTc. Over the days before discharge, electrocardiography demonstrated reduced QT-interval prolongation.

Conclusion: Life-threatening ventricular arrhythmia in a young female can be caused by QT-interval prolongation. It must be diagnosed and treated immediately to avoid mortality.

A follow-up approach to manage tachyarrhythmia and bradyarrhythmia in Ebstein’s anomaly patient
Authors: Setyowati Danti Utami , Rizal Ardian
Published: February 2025

Background: Ebstein’s Anomaly (EA) is a rare heart defect that can cause a number of problems, including arrhythmias. They exhibit a greater rate of recurrence compared to those with normal hearts. High-definition (HD) mapping and three-dimensional (3D) ablation are new techniques that may be suboptimal, attributed to anatomical characteristics. The management tactics employed may necessitate modification in accordance with personal traits.

Case Report: A 37-year-old male presented with intermittent palpitations over years. The electrocardiogram (ECG) is changing overtime such as supraventricular tachycardia (SVT), ventricular tachycardia (VT) and atrial fibrillation (AF). Echocardiography shown typical features of EA. During ablation, multiple atrial tachycardias were induced. Throughout the observation period, the patient exhibited complications related to several arrhythmia recurrence. In the end he suffered from total atrioventricular block (TAVB), leading to the decision to undergo a permanent pacemaker procedure. We postulated that specific characteristics of the right atrioventricular groove structure observed in pathological samples of EA could explain less than ideal results in ablation procedures.

Conclusion: Managing arrhythmia in EA could be challenging. A prominent ridge alongside the lower atrioventricular groove is a typical characteristic in EA, and is associated with the clinical background of accessory pathways (AP). Understanding this anatomical aspect is important for electrophysiologists who work with this group of patients, since their management approaches may need to be adjusted.

Authors: Kurniawan Catur Rizky , Kurnianingsih Novi , Widito Sasmojo
Published: February 2025

Background: CVI manifests with a variety of clinical symptoms, spanning from varicose veins to venous ulcers, significantly impacting patients' daily lives. While traditional treatments such as compression therapy and surgery remain options, on endovenous laser treatment (EVLT) has emerged as a viable alternative. This article delves into the management of CVI, with a particular focus EVLT as a minimally invasive intervention. Through two case illustrations, it sheds light on the difficulties encountered when accessing the great saphenous vein (GSV) using the conventional antegrade approach, particularly in cases involving obesity and vasospasm. Consequently, a retrograde EVLT technique utilizing proximal GSV access, resulting in successful vein ablation with minimal complications. Overall, this approach presents a promising addition to the management of CVI, offering enhanced patient care and improved outcomes.

Case Presentation: Two patients with CVI and challenging antegrade GSV access underwent retrograde EVLT using proximal GSV access. Despite initial difficulties, including obesity and vasospasm, successful vein ablation was achieved with minimal complications. Post-procedural evaluations demonstrated significant symptomatic improvement, highlighting the efficacy of the retrograde technique.

Conclusion: Retrograde EVLT utilizing proximal GSV access proves to be a safe and effective alternative in cases where antegrade access is challenging. The technique offers simplicity, minimal complications, and high patient satisfaction, with outcomes comparable to traditional approaches. Extended follow-up studies are needed to confirm the long-term effectiveness of retrograde EVLT compared to antegrade methods. Overall, retrograde EVLT presents a valuable option for managing CVI, particularly in patients with anatomical complexities or vasospasm, contributing to improved patient care and outcomes.

The complex relationship between arterial carbon dioxide levels and acute heart failure: implications for prognosis and management
Authors: Afifah Yuri , Prasetya Indra , Anjarwani Setyasih , Pashira Andranissa Amalia
Published: February 2025

Acute Heart Failure (AHF) can affect carbon dioxide levels in the body by altering the balance between ventilation and carbon dioxide production, leading to either hypocapnia or hypercapnia. Arterial carbon dioxide (CO2) levels are essential for maintaining respiratory function and acid-base balance. However, the relationship between arterial CO2 levels and AHF remains complex and not fully understood. Diverse factors affect arterial CO2 levels in patients with AHF, including neurohormonal activation, respiratory compensation for hypoxemia, and changes in pulmonary perfusion. Hypocapnia, characterized by low arterial CO2 levels (PaCO2 < 35 mmHg), is commonly observed in AHF due to hyperventilation-driven respiratory alkalosis secondary to pulmonary congestion. It showed a strong connection with the survival rates of patients following a cardiac arrest. Nevertheless, elevated levels of carbon dioxide in the blood, known as hypercapnia, with a partial pressure of arterial carbon dioxide (PaCO2) exceeding 45 mmHg, can also arise in the later phases of acute heart failure (AHF), indicating fatigue in respiratory muscles or deterioration in pulmonary edema. Abnormal arterial CO2 levels have been associated with increased morbidity and mortality in AHF patients, serving as a valuable prognostic marker.

When to consider takotsubo cardiomyopathy in menopausal elderly woman presenting chest pain
Authors: Aziz Indra Jabbar , Rohman Mohammad Saifur
Published: February 2025

Background: An elderly menopausal woman presenting with chest pain in the emergency department may have coronary artery disease (CAD), Takotsubo cardiomyopathy, or other conditions. It is crucial to conduct a thorough diagnostic evaluation in menopausal elderly woman.

Case illustration: A 77-year-old postmenopausal woman presenting with first-onset chest pain after having familial issues and severe psychological stress was admitted to the emergency department. She had no identifiable risk factors for CAD, and her physical examination revealed no significant abnormalities. The electrocardiogram (ECG) indicated non-specific ST-segment elevation in leads V3-V6. Serial ECGs showed an evolution of ST-segment elevation that did not align with the typical pattern observed in STEMI. Despite the elevation in cardiac enzymes in the previous hospital, unfortunately, serial cardiac enzymes were inconsistently normal in our hospital. Therefore, these findings implied that the patient's condition might not be ACS, and we cannot rule out the possibility of Takotsubo syndrome. The patient underwent coronary angiography (DCA) and The DCA results revealed normal coronary with suspicion of apical ballooning of the left ventricle as observed from cine angiography. Subsequent echocardiography demonstrated apical akinesis with basal hyperkinesis, the large area of dysfunctional myocardium extending beyond the territory of a single coronary artery and characteristic apical ballooning resembling an octopus trap, consistent with the diagnosis of Takotsubo syndrome. The patient was managed conservatively with supportive care. Her symptoms improved, and she was discharged after five days.

Conclusion: This case highlights the importance of considering takotsubo cardiomyopathy in menopausal elderly woman with no risk factor of CAD presenting with chest pain after having psychological stress.

Use of SAPS 3, APACHE IV, and GRACE as prognostic scores for acute coronary syndrome patients in the cardiovascular care unit
Authors: Yudha Tria , Prasetya Indra
Published: February 2025

A grading system based on disease severity has been widely used in intensive care units (ICUs) since around 1980. These systems are used to predict mortality and assess severity in clinical trials. Simplified Acute Physiology Score 3 (SAPS3) and Acute Physiology and Chronic Health Evaluation Score (APACHE IV) are prognosis ratings that can predict in-hospital mortality within the first hour of ICU care. Although these technologies have been widely employed in the ICU, they have yet to be commonly deployed in the cardiovascular care unit (CVCU) due to different patient populations. Intensive care doctors typically employ the standard prognostic

scores, SAPS3 and APACHE IV, which were generated from diverse populations of critically ill patients. Although these scores are the most widely used early versions, APACHE IV and SAPS 3 do not include acute coronary syndrome patients. The Global Registry of Acute Coronary Events (GRACE) score has performed the best; this may be because of its straightforward design, which does not distinguish between individuals with SCA and those without ST-segment elevation. Our review article attempts to evaluate the performance of standard predictor scores, namely SAPS 3, APACHE IV, and GRACE, on patients with cardiovascular emergencies. Thus, these score systems can precisely assess the relationship between mortality prediction scores and outcomes of patients admitted to the CVCU rapidly and comprehensively.

Indonesia memiliki hasil buah yang melimpah, namun rentan rusak oleh faktor mekanik, kimia, dan mikrobiologi. Penggunaan edible coating berbahan kitosan, ekstrak aloe vera, dan pektin jeruk dapat menjadi alternatif kemasan untuk melindungi buah dari kontaminasi. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan ekstrak aloe vera dan kitosan dalam pembuatan edible coating dari pektin jeruk terhadap karakteristik buah pir potong. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) 2 faktorial yaitu konsentrasi aloe vera dan kitosan untuk menguji kombinasi edible coating pada buah pir potong dengan parameter mutu seperti susut bobot, pH, dan total padatan terlarut (TPT) selama 6 hari penyimpanan pada suhu ruang, serta dianalisis menggunakan Two Way ANOVA. Tahapan penelitian diawali dengan pembuatan larutan kitosan, pembuatan edible coating dari aloe vera, kitosan, pektin serta pengaplikasian edible coating pada buah pir. Setelah itu dilakukan pengujian mutu antara lain susut bobot, pH,kadar vitamin C, total padatan terlarut (TPT) dan organoleptik. Hasilnya menunjukkan bahwa edible coating dari ekstrak aloe vera, kitosan dan pektin berpengaruh dalam mengurangi susut bobot, mempertahankan TPT, pH, kadar vitamin C, dan kualitas organoleptik, memperpanjang masa simpan buah dibandingkan dengan buah pir tanpa perlakuan (kontrol). Nilai persentase dari susut bobot mencapai 0,0389%, pH 3,5, TPT 7.0°Brix, kadar vitamin C 24,75 mg/10g, kesukaan warna hingga skor 3,3, kesukaan aroma sampai skor 1,9 dan kesukaan tekstur mencapai skor 2,4. Konsentrasi optimal diperoleh pada konsentrasi 2% aloe vera dan 2% kitosan (V1K2).
Enriching experiences: Unpacking Kazakhstani EFL teachers' attitudes and readiness for intercultural approach

Published: February 2025

The present study aims to unpack the university English as a foreign language (EFL) teachers’ practices and attitudes towards intercultural approach (ICA) and identify the prospective EFL teachers’ level of preparedness to implement ICA. For this purpose, 36 EFL teachers and 45 master students doing a program on TEFL (Teaching English as a foreign language) were chosen to collect data through a survey and project analysis. Our findings indicate that despite recognising the intercultural paradigm in teaching EFL, embedded in all Kazakhstani regulations and the increasing tendency to use authentic textbooks, there is a lack of sound preparedness to implement ICA on the part of both pre-service and in-service EFL teachers. The results suggest that two-thirds (66.6%) of master students could not identify all intercultural attributes in the coursebook. In-service teachers’ agreement level on the importance of ICA is high; however, they lack practical skills for nuanced integration of ICA in EFL classrooms. This article can serve as a discussion platform to tackle challenges associated with ICA implementation in higher education not only in Kazakhstan but in the international context, as this issue is topical for many countries in the world where English is taught as a foreign language.

Published: February 2025

This study examines the role of teaching experience and teacher-parent collaboration in managing students' disruptive behaviours in secondary schools in Nigeria. A total of 367 teachers participated in the study. Data were collected using a questionnaire and analysed using one-way Analysis of variance and the Pearson moment correlation. The findings indicate differences in teachers' years of teaching experience determine how students’ disruptive behaviours are managed. However, a non-significant weak positive correlation was found between teacher-parent collaboration and students' disruptive behaviour management (r = 0.95, p =.068). These results underscore the importance of teachers teaching experience in ameliorating disruptive behaviours.    Based on these findings, teacher mentoring programme involving peering of senior and junior teachers as mentor and mentees respectively for effective classroom management should be implemented.
