Reducing door-to-balloon time in STEMI patients through instant messaging: An empirical study during the COVID-19 pandemic
Authors: Yang Yi-Chun , Liu Chih-Tsung , Wu Bao-Tzung 
Published: December 2024

Abstract

Background:
Percutaneous coronary intervention (PCI) is the preferred treatment for ST-segment elevation myocardial infarction (STEMI). Guidelines recommend maintaining the door-to-balloon time (DTBT) within 90 min to improve treatment outcomes and minimize complications. However, the coronavirus disease 2019 pandemic has posed additional challenges for the healthcare systems.

Objectives:
This study aims to evaluate the impact of the LINE instant messaging system on DTBT in STEMI patients, focusing on its role in improving communication between emergency department physicians and catheterization lab personnel.

Methods:
This retrospective study analyzed data from STEMI patients hospitalized in a regional hospital in central Taiwan. Patients were categorized into a control group (2020–2021, standard care) and an experimental group (2022–2023, care enhanced with LINE instant messaging). Medical records were retrospectively reviewed and analyzed.

Results:
A total of 269 STEMI patients were included (experimental group: 129 and control group: 140). The proportion of patients achieving door-to-electrocardiogram time (DTET) ≤10 min was similar in the two groups (experimental: 92.2% and control: 93.6%; P = 0.674). Similarly, there was no significant difference in DTBT ≤90 min (experimental: 78.9% and control: 78.6%; P = 0.956) or discharge outcomes (experimental: 3.1% and control: 2.1%; P = 0.624).

Conclusion:
DTBT ≤90 min was positively correlated with DTET ≤10 min (r = 0.244, P < 0.01) and door-to-catheter room time (DTCT; r = 0.461, P < 0.01). The use of LINE instant messaging streamlined emergency room communication and reduced inefficiencies, but uncontrollable factors during the pandemic continued to affect PCI times. This study highlights the potential of instant messaging to improve DTBT in STEMI patients.

Authors: Shrivastava Saurabh RamBihariLal , Marar Anup Mukund , Bobhate Prateek Sudhakar 
Published: December 2024

Abstract
Medical students during their period of training are exposed to lots of stress owing to the pressure of academics, adaptation to new living conditions, and peer-related factors. Mindfulness refers to conscious efforts to encourage healthcare professionals, including medical students to live in the current moment, without being concerned about the events in the past or the future. Training of students in mindfulness methods is expected to play a defining role in reducing stress among them, which will in turn aid in promoting their overall well-being. Even though training of medical students in mindfulness has been recognized as the need of the hour and has multiple merits for the students, patients, and healthcare delivery services, there have been some challenges in its successful implementation in any medical institution. In conclusion, training medical students in mindfulness methods is expected to promote personal well-being and the development of vital professional attributes. However, as the process of implementation in medical institutions might be accompanied by different challenges, it is the need of the hour to integrate mindfulness initiatives within the existing curriculum and support the same with faculty training and administrative support.

Comparative effectiveness of supervised versus unsupervised video training on hysteroscopic camera navigation performance among OB-GYN residents at Tertiary Government Hospital: A randomized controlled trial
Authors: Cantor Margarita Romulo , Umipig-Guevara Zoraida R. , Aquino-Aquino Prudence V. , Baltazar Maria Rica Arandia 
Published: December 2024

BACKGROUND:
Simulated video training has emerged as an effective method to enhance the surgical skills. However, in the local context, there is an absence of data contrasting the outcomes of unsupervised video training with the conventional supervised approach in surgical skill development.

OBJECTIVE:
The objective of this study was to evaluate and contrast the performance score and total operating time between unsupervised video training simulations and supervised video training simulations, specifically in the domain of 30° hysteroscopic camera navigation.

MATERIALS AND METHODS:
A single-blinded randomized controlled trial involved 24 obstetrics and gynecology residents in a tertiary government institution. Participants were randomized into Group A (unsupervised video training) and Group B (proctor-supervised simulation training). Utilizing a uterine model, both groups undertook nine designated tasks. The training process included a pretest simulation, 5 training repetitions, and a concluding posttest simulation. The principal investigator documented operating times and hand movements posteach session. Subsequently, a blinded Philippine Society for Gynecologic Endoscopy board-certified gynecologic endoscopist assessed these videos, using the Global Hysteroscopy Rating Scale for scoring.

RESULTS:
The total operating time and performance score during posttest among Group A and Group B showed no significant difference (Group A 0.77 ± 0.19 min Group B 0.71 ± 0.15 min) (P = 0.377) (Group A 13.50 ± 1.73 Group B 13.83 ± 1.53) (P = 0.622) which suggest that participants performed comparably regardless of instructional method. On the Global Rating Scale (GRS) score, higher percentage of participants from Group B showed improved performance on respect for tissue, time and motion, and handling of hysteroscope as compared to Group A.

CONCLUSION:
The video-based training simulation is effective as expert proctoring in hysteroscopic camera navigation. However, there was slightly greater improvement in the GRS scores in the proctor supervised group which suggest that feedback from proctors has a positive impact on the performance.

Authors: Brotons-Muñoz Elena , Ventura-Abreu Néstor , Muniesa María J. , Millá Elena , Torras-Sanvicens Josep , Pazos Marta 
Published: December 2024

PURPOSE:
Elevated intraocular pressure (IOP) following corneal transplantation (CT) presents a significant risk for graft failure and visual impairment. This retrospective cohort study aims to evaluate the outcomes of different glaucoma surgeries and corneal graft survival rates in patients who have undergone CT.

METHODS:
A single-center, retrospective cohort was conducted on all patients at our tertiary hospital who had received glaucoma surgery following corneal transplant surgery from 2020 to 2023. Inclusion criteria were defined as patients over 18 years of age, with at least 6 months of follow-up. The primary outcomes included corneal graft survival and glaucoma surgery success.

RESULTS:
Twenty eyes from 18 patients who underwent glaucoma procedures after a corneal transplant were analyzed. Glaucoma surgery success – IOP level within limits (>6 mmHg but below the preset target), no further glaucoma surgeries, and no postoperative severe vision loss due to complications – was achieved in 80% of cases, with no significant differences observed among techniques. Corneal graft survival at 6 months (a functional transplant that does not require a regraft procedure and with central graft clarity) was 55%, with higher rates observed in patients undergoing nonpenetrating deep sclerectomy (NPDS), XEN45 gel stent (XGS), or PAUL glaucoma implant (PGI) procedures compared to trabeculectomy and Ahmed valve. Only 35% of patients experienced minor complications, and no major adverse events were reported.

CONCLUSION:
In our retrospective cohort study, surgical approaches such as NPDS, XGS, or PGI showed the most favorable outcomes regarding glaucoma surgery success and corneal graft survival rates.

Published: December 2024

Abstract

Purpose:
Ocular injuries frequently result in significant eye-related health issues, often leading to severe and sometimes irreversible vision impairment. This case series aims to highlight the presentation, management and outcomes of various ocular injuries over a 1-month period, emphasizing the necessity for timely and effective intervention.

Methods:
This case series includes 11 patients with varying degrees of ocular trauma, who presenting to an emergency department over a month. Each case was documented in detail, including patient demographics, mechanism of injury, clinical findings, surgical interventions, and postoperative outcomes. The primary focus was on the initial surgical management and subsequent referral for specialized care when necessary.

Results:
Case 1 describes a 4-year-old boy who sustained a corneal laceration and cataract, managed with corneal suturing and lens extraction. Case 2 describes a 13-year-old boy who suffered a sclerocorneal tear with iris prolapse, treated with wound exploration and repair. Case 3 described an 18-year-old boy with a thorn injury who underwent corneal repair and anterior vitrectomy. Cases 4-11 include various injuries, such as full-thickness corneal tears, hyphema, conjunctival lacerations, and lens dislocation, each managed with appropriate surgical intervention and postoperative care. The cases underscore the complexity of ocular trauma management and the critical need for prompt, skilled intervention. The variability in injury mechanisms and severity highlights the importance of tailored surgical approaches and the role of early referral to specialized care for optimal outcomes.

Conclusion:
Ocular trauma presents diverse challenges requiring prompt and effective management to prevent long-term visual impairment. This case series emphasizes the importance of comprehensive emergency care and specialized follow-up to address the multifaceted nature of ocular injuries.
Post-traumatic Corneal Ocular Surface Squamous Neoplasia: A Case Report
Authors: Wali Keerti , Sankolli Nikita , Nerune Savitri 
Published: December 2024

Abstract
We report a rare presentation of limbus-sparing ocular surface squamous neoplasia (OSSN) over post-traumatic adherent leucoma. A 32-year-old healthy male presented with a pedunculated fleshy corneal mass overlying an adherent leucoma secondary to self-healed full-thickness corneal laceration, with an adjacent pinguecula separated by a clear normal limbus. AS-OCT confirmed the separation of corneal epithelial mass from underlying iris tissue by thinned scarred corneal stroma. An excisional biopsy with 2mm conjunctival margins and a limbal conjunctival autograft was performed. A feeder vessel was observed at the base of the corneal lesion. Histopathological evaluation showed moderately differentiated squamous cell carcinoma. Adjuvant Interferon alfa 2b chemotherapy for three months ensured complete clearance with no recurrence at follow-up. This case highlights the traumatic etiology of OSSN development without limbal involvement. Immediate corneal tear repair may have prevented its occurrence and the need for long-term chemotherapy.
Comparison of OCT Angiography Parameters after Administration of Intravitreal Brolucizumab versus Ranibizumab in Exudative Age-related Macular Degeneration
Authors: Moses Sanjitha Vilma , Varman Aadithreya , Balakumar Dinesh , Varman Arulmozhi 
Published: December 2024

Abstract

Purpose:
To compare the OCT angiography (OCTA)–derived parametric changes before and after intravitreal administration of ranibizumab and brolucizumab in patients with neovascular age-related macular degeneration (ARMD) and to compare the changes between the two groups.

Methods:
This retrospective cohort study was done on 68 eyes with neovascular ARMD: 34 received injection ranibizumab and 34 received brolucizumab in a stratified manner. Central foveal thickness (CFT) and OCTA parameters like vessel density (VD), superficial capillary plexus (SCP), deep capillary plexus (DCP), foveal avascular zone, (FAZ), fractal dimension (FD) were assessed. The scans were repeated 1 month postinjection.

Results:
In total, 46% had type 1 CNVM and 54% had Type 2 CNVM. In both the ranibizumab and brolucizumab group, the corrected visual acuity showed comparable significant improvement 1 month postinjection. The CFT showed significant reduction in both, more significant in brolucizumab. OCTA showed a minimal nonsignificant reduction in the VD, SCP and DCP at 1 month, which were not significantly different. The FAZ and FD showed a significant increase and reduction, respectively, in the brolucizumab group, unlike the ranibizumab group.

Conclusion:
OCTA changes suggest that anti-VEGF drugs produce no change in the capillary density. A reduction in structural architecture of smaller capillary branches i.e. fractal dimension and increase in FAZ is noted with brolucizumab, suggesting that some structural alterations of retinal microvasculature do exist with the drug.

Abstract

Context:
Retinopathy of prematurity (ROP) is one of the leading causes of preventable childhood blindness.

Aims:
To study the profile and risk factors of ROP among infants at a district hospital in Goa.

Settings and Design:
Retrospective observational study.

Materials and Methods:
The study included babies screened for ROP at the district hospital from July 2019 to October 2022. The screening was conducted by a single trained ophthalmologist using binocular indirect ophthalmoscopy, and the examination findings along with risk factors were recorded in ROP documentation charts.

Statistical Analysis Used:
Continuous variables were analyzed using the student t test. Categorical variables were analyzed using the Chi-square test. A P < 0.05 was considered statistically significant.

Results:
A total of 232 babies were included in the study and were screened for ROP. ROP was detected in 24 babies (10.35%), and 208 babies did not develop ROP. There was a significant relationship between the occurrence of ROP and low gestational age (P < 0.001), lower birth weight (P < 0.001), respiratory distress syndrome (RDS) (P < 0.001), intraventricular haemorrhage (IVH) (P = 0.003), and patent ductus arteriosus (PDA) (P < 0.001).

Conclusions:
In this study, 10.35% of the babies screened developed ROP. Low gestational age, lower birth weight, RDS, IVH and PDA were significant risk factors for the occurrence of ROP.

This examination could play a role in allowing residents to improve their skills free from the burdens of space and time limitations. Additionally, residents developed the confidence to examine and diagnose children with strabismus.

Conclusion:
We strongly believe that these examinations aimed at assessing improvements in strabismus will significantly enhance residents’ abilities to diagnose and treat this condition effectively. This study was aimed to help ophthalmology residents; it could be beneficial for trained ophthalmologists to maintain or practice their skills.
Образы Монголии в советской живописи второй половины XX века (по материалам собрания Национальной галереи искусства, Улан-Батор)
Authors: Сарантуяа Б. , Яйленко Е.В. 
Published: December 2024

В статье рассматриваются произведения советских художников, посвященные Монголии и ныне хранящиеся в отдельном фонде Национальной художественной галереи Монголии в Улан-Баторе (в общей сложности более ста работ). В числе тех, кто трудился над их выполнением, были как малоизвестные ныне художники, так и крупные мастера советской школы живописи (Ф.С. Торхов, А.В. Казанский, Ю.А. Походаев, Д.-Н.Д. Дугаров). Рассматриваемый в статье изобразительный материал до сих пор не был известен специалистам и впервые вводится в научный оборот. На примере искусствоведческого анализа произведений, принадлежащих к жанрам портрета и пейзажа, а также бытовых сцен, сделана попытка выявить некоторые общие закономерности художественного творчества, влиявшие на формирование образа Монголии в советской живописи последней трети XX века. Особое место уделено рассмотрению вопроса о том, как знакомство с произведениями монгольских художников отразилось на отборе жизненных впечатлений и способов их изобразительной репрезентации.
The article is devoted to the research of artworks by Soviet artists dedicated to Mongolia and now kept in a separate fund of the National Art Gallery of Mongolia in Ulaanbaatar (in total, more than one hundred pieces). The artists who worked on these pieces included both lesser-known figures and prominent members of the Soviet school of painting, such as F.S. Torkhov, A.V. Kazansky, Y.A. Pokhodaev, and D.-N.D. Dugarov. The artistic material considered in this article has not yet been known to specialists and is being for the first time introduced into scientific discourse. This article employs an art historical analysis of works belonging to the genres of portraiture, landscape, and domestic scenes to identify general patterns of artistic creativity that influenced the formation of the image of Mongolia in Soviet painting during the latter third of the 20th century. Special attention is given to the question of how acquaintance with works of different Mongolian artists influenced the perception of everyday life and ways of the pictorial representation of visual experience.

Published: December 2024

Цели и задачи данной статьи заключаются в обращении к творчеству крымских художников ХХ века, определении значения деятельности Н.С. Барсамова для культурной жизни Феодосии, выявлении художественно-содержательных приоритетов его учеников: С.Г. Мамчича, В.А. Соколова, Н.А. Шорина, П.К. Столяренко — на ранних этапах творчества. Также в работе приводятся факты биографии Н.С. Барсамова, свидетельствующие о значимости его деятельности как директора Феодосийской картинной галереи имени И.К. Айвазовского и основателя художественной школы. Изобразительным материалом исследования послужили живописные произведения Феодосийской картинной галереи имени И.К. Айвазовского и Симферопольского художественного музея. Также изучены статьи, опубликованные в специализированных журналах и искусствоведческих сборниках, каталоги выставок (всесоюзных, республиканских, персональных, отдельных художественных объединений), воспоминания и письма участников процесса. В результате системно-исторического жанрового анализа удалось выстроить жанровую хронотипологию творчества художников. Для исследования отдельных произведений и выявления общих признаков применен формально-стилистический метод. Сравнительно-аналитический метод позволил изучить становление каждого представителя рассматриваемого живописного направления и выявить общие тенденции и влияние предшественников.
This article aims to address the work of Crimean artists of the twentieth century, determine the significance of N.S. Barsamov's activity for the cultural life of Theodosia, and identify the artistic and content priorities of his students S.G. Mamchich, V.A. Sokolov, N.A. Shorin, and P.K. Stolyarenko in the early stages of their creative development. Furthermore, the work presents facts from the biography of N.S. Barsamov, which serve to illustrate the significance of his role as the director of the Theodosia Picture Gallery named after I.K. Aivazovsky and the founder of the painting school. The study's artistic material comprised paintings from the Theodosia Picture Gallery named after I.K. Aivazovsky, and the Simferopol Art Museum. The articles published in specialised journals and art history collections, exhibition catalogues (all-union, republican, personal, individual art associations), memoirs and letters of the participants in the process were subjected to detailed analysis. A system-historical genre analysis enabled the construction of a genre chronotypology for the artists' work. The formal and stylistic analysis was employed to examine individual works and identify common features. The comparative-analytical method facilitated the study of the formation of each representative of the considered painting direction and the identification of common trends and the influence of predecessors.
