Factors Influencing Patients' Decisions to Use Health Services for Retreatment at Putri Hijau Medan TK II Hospital in 2023
Authors: Prayoga Muhammad Arif , Theo Deli , Nasution Ramadhani Syafitri
Published: June 2024

Patient behavior as consumers in utilizing health services, including the decision to seek re-treatment, is influenced by several factors such as the quality of doctor/nurse services, distance, facilities, and speed of service. This study aims to analyze the factors that influence patients' decisions to utilize health services for repeat treatment. The research method used was quantitative with a cross-sectional design, carried out at the Putri Hijau Level II Hospital in Medan. A sample of 247 people was selected using the accidental sampling method from a population of 3,946 people. Data analysis used univariate, bivariate chi-square, and multivariate approaches with multiple logistic regression at a 95% confidence level. The research results show that the quality of doctor/nurse services, distance, facilities, and speed of service have a significant influence on the patient's decision to seek treatment again. Meanwhile, factors such as age, gender, education, and employment do not have a significant effect. The most dominant factor is facilities, where respondents who feel that hospital facilities are good have a higher chance of undergoing repeat treatment. This research concludes that factors such as the quality of doctor/nurse services, distance, facilities, and speed of service have a significant influence on patients' decisions in utilizing health services for re-treatment at Putri Hijau Level II Hospital in Medan. It is recommended that the hospital allocate a budget to improve facilities that are still lacking and improve new service facilities to increase public confidence in seeking treatment again.

Authors: Sani Ibrahim , Binji Yusuf Ahmad
Published: June 2024

Malaria remains a threat and exert economic and social burdens in most communities in Africa. Medicinal plants have played an important role in the treatment of malaria worldwide. Several studies have shown that, the efficacies of most antimalarial agents are compromised by the emergence of drug-resistant Plasmodium species. This research was aimed at evaluating the synergistic effect of some medicinal plants used for the treatment of malaria in Sokoto metropolis, Nigeria. Three (3) plants samples were collected and used for the study. They include Azadirachta indica, Carica papaya and Psidium guajava leaves. They were dried and extracted using 50% methanol. Qualitative phytochemical analysis of three (3) plant extracts was carried out using standard methods. The individual extracts and their combinations were subjected to in vivo antiplasmodial activity. Synergistic effect was determined by checkboard method. Phytochemical screening of Azadirachta indica, Carica papaya and Psidium guajava leaves methanol extracts all revealed the presence of phenols, tannins and glycosides in all the extracts. Extract combination of Carica papaya and Psidium guajava demostrated 100% reduction of parasitemia at both 100 and 200 mg/kg b. wt respectively after 72-hour treatment. Determination of synergistic activity showed that Fractional Activity Index (FAI) of Carica papaya and Psidium guajava is greater than 1.0, hence the effect was considered to be additive. The findings of this study had provided scientific bases supporting the traditional use of the plants for the treatment of malaria.
Physicians' Evidence-Based Clinical Decision-Making Practices for New Drug Prescriptions: A Qualitative Study
Authors: Nath Akhi
Published: June 2024

Failure to use research evidence to inform decision-making is one of the reasons for the inappropriate prescribing behavior of physicians. The purpose of this study is to understand the process of physicians’ evidence-based clinical decision-making for new drug prescriptions. Eleven semi-structured interviews were conducted and thematic coding was used for data analysis. The findings suggest that at the point-of-care (POC), given the time constraints, physicians seek information from readily accessible and reliable sources such as medical websites. They use pre-appraised information sources as well as their professional networks to access critically appraised information. Expert knowledge sources (e.g., specialists, colleagues) play a crucial role throughout the process, from information seeking to application in clinical decision-making. Medical information systems facilitating immediate access to summarized reliable evidence with features to connect to the communities of practice in real-time can be an effective strategy to improve physicians’ evidence-based practice for new drug prescriptions.
Geçmiş zaman morfemi -(X)p bağlamında Tuńukuk yazıtının 25-26. satırları üzerine bir değerlendirme
Authors: Ağca Ferruh
Published: June 2024

Türk dilinde ekler, asıl işlevlerinin yanında, işlevlerine yakın başka işlevler de yüklenmiştir. İşlevsel çeşitlilik özellikle çekim morfolojisine ait eklerde daha yaygındır. Türk dili gramerlerinde sıfat-fiil ya da isim-fiil olarak adlandırılan ekler de işlevsel bakımdan çeşitlenen ekler arasındadır. Bu eklerin bitimsiz fiillerdeki işlevlerinin yanı sıra bitimli / yüklemsel fiillerde zaman çekim kategorisine dahil oldukları gözlemlenmektedir. Türk dilinde genellikle zarf-fiil eki olarak yaygınlaşan -(X)p eki, Eski Türkçe metinlerde farklı işlevlerle karşımıza çıkmaktadır. Ek, bu dönemde çok yaygın olmasa da, eklendiği eylemleri kendisinden sonra gelen ismi niteleyen sözcüklere dönüştürmüştür. Keza -(X)p eki, Eski Türkçenin bütün çevrelerinde geçmiş zamanı işaretleyerek yüklemsel eylemlerin bir ögesi olmuştur. Bu makalede, anlamlandırmada kimi güçlüklerin görüldüğü Tuńukuk yazıtının 25-26. satırlarından hareketle, ilgili satırlarda –(X)p ekinin Türk dilinde baskın olan işlevinden farklı işlevler gösterdiği, benzer işlevin Eski Türkçenin diğer çevrelerinde de temsil edildiği ve Türk dilinin 13. yüzyıldan sonraki metinlerinde yaygınlaşan geçmiş zaman işlevinin kaynağı olduğuna dair elde edilen sonuçlar, ekin kullanılış şekilleri ve anlamları dikkate alınarak değerlendirilmiştir. Bu çerçevede –(X)p ekinin Türk dilinin erken tarihli metinlerinden itibaren aynı zamanda geçmiş zaman eki olarak kullanılmaya başlandığı, üzerine şahıs zamirlerini almak suretiyle şahıslara göre çekimlendiği, 13. yüzyıldan sonra görülen –(X)p turur yapısının Eski Türkçeden sonra ortaya çıktığı gibi tespitler, metinlerden elde edilen tanıklar yardımıyla yorumlanmıştır.
Meynard ın Lehce-i Osmani yi tanıtımından hareketle Dictionnaire Turc-Français deki sözlüksel tercihlerin kaynağı
Authors: ALTUN İrem Işıl
Published: June 2024

Sözlüklerin tipik özellikleri, muhtemel kullanıcıları belirleyen ve kullanıcıların beklentilerinin ne derece karşılanacağının anlaşılmasını sağlayan unsurlardır. Meynard’ın Türk dili araştırmaları bakımından bilinen en önemli eseri Dictionnaire Turc-Français, bugüne kadar böyle bir incelemeye tabi tutulmamıştır. Dolayısıyla bugün için tarihî bir sözlük özelliği sergileyen Dictionnaire Turc-Français’nin hangi araştırmalara kaynaklık edebileceği tam olarak bilinmemektedir. Bu türden bir çalışma yapmak istenildiğinde ise eldeki bilgilerin, sözlük bilimsel ölçütlere göre eksik kaldığı görülmüştür: Meynard sözlüğü hazırlarken izlediği yolu anlatmamış; yalnızca yararlandığı kaynaklardan, ulaşmayı hedeflediği kullanıcı kitlesinden ve genel amacından bahsettiği bir giriş yazmıştır. Sözlüğün kullanımına ilişkin herhangi bir bilgi vermemiştir. Bundan ötürü daha önce üzerinde ayrıntılı bir çalışma yapılmayan Dictionnaire Turc-Français’nin sözlük bilimsel yöntemlerle incelenebilmesi ve sözlükçünün tutumunun anlaşılabilmesi için dış verilere başvurulması gerekli görülmüştür. Bu amaçla, Meynard’ın sözlüğünün kaynakları arasında saydığı Lehce-i Osmani hakkında 1876’da Journal Asiatique’te yayımlanan tanıtım yazısı incelenerek veri toplanmıştır. Dictionnaire Turc-Français gibi, araştırma konusu edilen tanıtım yazısı da daha önce incelenmemiştir. Bu araştırma kapsamında Meynard’ın Lehce-i Osmani ile ilgili görüşleri tercüme edilmiş, olumlu ve olumsuz eleştirileri karşılaştırmalı bir şekilde değerlendirilmiştir. Karşılaştırma sırasında hem dönemin kaynaklarından hem de modern kaynaklardan yararlanılmıştır. Görüş ve eleştirilerde yer alan söz varlığı seçimi, köken bilgisi, ünlülendirme sistemi gibi konuların Dictionnaire Turc-Français’deki durumları araştırılmıştır. Araştırma sonucunda Dictionnaire Turc-Français’nin madde düzeni ve söz varlığı seçimine Lehce-i Osmani’nin yön verdiği, köken bilgisi ve sesletim kategorilerindeki düzensizlik konusunda Lehce-i Osmani’nin ana kontrol noktası olması gerektiği tespit edilmiştir.

Mujeres negras en el carnaval de Buenos Aires, c. 1816-1890: transgrediendo fronteras de género, clase y raza
Authors: Adamovsky Ezequiel
Published: June 2024

En el siglo XIX, el contexto del carnaval colocaba a las mujeres afrodescendientes de Buenos Aires entre dos dinámicas cruzadas: la de una jerarquía social que las arrojaba al escalón más bajo y la de una fiesta que prometía, por un momento, poner en suspenso algunas de las reglas que la organizaban. ¿En qué medida pudieron encontrar en el carnaval ocasiones para transgredir las fronteras de clase, raza y género que aseguraban la estabilidad del orden social? Este trabajo apunta a responder esa pregunta mediante un análisis detallado de las maneras en las que participaron de la fiesta. Se apoya en información de una amplia variedad de periódicos (comunitarios y blancos), revistas, libros, y otros impresos que permiten reconstruir la escena carnavalesca en la ciudad entre el período de grandes cambios que se abre con la Independencia y la década de 1890, cuando la participación de afroporteños en el carnaval había alcanzado su mayor intensidad.

Authors: Guzmán Florencia
Published: June 2024

En esta investigación, se resalta la importancia de estudiar la vida cotidiana de las mujeres negras durante el gobierno de Juan Manuel de Rosas (1830-1852). En tanto, y a pesar de ser reconocido su papel político, son escasos los estudios empíricos realizados sobre ellas, y a menudo prevalecen las representaciones estereotipadas y racializadas de género. El objetivo de este estudio es analizar la documentación del archivo de policía para examinar las experiencias y prácticas concretas de estas mujeres en la ciudad de Buenos Aires, en un periodo de cambios, guerra, coacciones y lucha política, así como de abolicionismo gradual y sus efectos en las vidas individuales y colectivas.

Representaciones heterodoxas y fronteras culturales: la mujer negra en Croquis y siluetas militares de Eduardo Gutiérrez
Authors: Bocco Andrea
Published: June 2024

El trabajo aborda un corpus considerado como literatura de frontera. Reflexiona sobre cómo un enunciador masculino, blanco, letrado, citadino construye personajes negros en Argentina a finales del siglo XIX, particularmente una mujer. Se parte de la hipótesis de que este género configura representaciones sociales heterodoxas que corroen el discurso homogeneizador de la nación. Los sujetos fronterizos traducen a la ambivalencia y la multiplicidad lo que el Estado busca configurar como matriz única cultural. Particularmente se analizan qué operaciones heterodoxas se ponen en juego en representaciones femeninas negras en la frontera.

A Hymn for the Citizens of Color. Parody-Song, the French Revolution, and the Abolition of Slavery
Authors: Palm Raoul Manuel
Published: June 2024

With the abolition of slavery in France and its colonies in 1794, ensuing from the abolition of slavery in Saint-Domingue 1793, free people of color and enslaved Africans reached their goal in the struggle for emancipation. Throughout the early French Republic, people gathered to celebrate this milestone of revolutionaries’ ideals: Liberty, Equality, Fraternity. People of color took part in the festivities as well. One woman of color, Marie-Thérèse Lucidor Corbin, created a hymn for the people of color, to honor the struggle for emancipation, and to celebrate the abolition of slavery. This hymne des citoyens de couleurs was sung during the festivities to the melody of the well-known song “La Marseillaise”, which today is France´s national anthem, making the hymn a musical parody of the original song. In this article, I combine findings from musicology and sound history with sources and research results from the Age of Revolutions as well as the History of free people of color and women of color in particular, while examining the practice of creating parody-songs during the French Revolution. I argue that Corbin´s parody of the Marseillaise is a way to link people of color's struggle with the ideals of the French Revolution and their fight for the human rights that the French Revolution in principle guaranteed them.

Authors: Araújo de Oliveira Denilson
Published: June 2024

Considerado até hoje o álbum mais importante de rap no Brasil, Sobrevivendo no Inferno é o quarto álbum de estúdio do grupo Racionais MC’s e um dos acontecimentos mais marcantes da cultura brasileira nas últimas décadas. Reconhecido nacionalmente como o mais importante grupo de rap brasileiro de todos os tempos, o grupo Racionais MC’s lançou este álbum em 1997, num momento marcado pela violência e brutalismo policial, especialmente contra a população negra e pobre, o que ficou conhecido como genocídio negro. Sobrevivendo no Inferno é um álbum com 12 títulos e pouco mais de 72 minutos que traça uma radiografia do negro e das cidades brasileiras, especialmente a cidade de São Paulo. Este álbum é marcado por uma narrativa contundente do drama negro nas cidades brasileiras. Mais de um quarto de século após o lançamento, as músicas cantadas por Mano Brown, Edi Rock, Ice Blue, mixadas por KL Jay e com várias participações especiais de cantores das quebradas de São Paulo revelam inúmeras dimensões das nossas desigualdades e do racismo brasileiro. O objetivo do nosso trabalho é analisar a relação entre raça, racismo e espaço urbano no álbum Sobrevivendo no Inferno do grupo Racionais MC’s. Quais as permanências, as mudanças e os retrocessos da questão urbana e racial brasileira que as músicas narradas naquela época apresentam hoje?.

Streptococcus pneumonia is among the major causative agents of respiratory tract infections and colonizes the nasopharyngeal cells of asymptomatically healthy individuals. Prevalence and antibiotics sensitivity of Streptococcus pneumonia amongst residents in a rural setting was evaluated. A total of 250 nasal swab samples (125 males and 125 females) were collected using sterile swab sticks. Administration of open-ended questionnaires, culture of the samples, identification of isolates, antimicrobial sensitivity test and determination of prevalence rate were all done using standard protocols. Out of the 250 samples collected, 35 were positive for S. pneumonia giving an overall prevalence of 14%. Based on sex, the prevalence rates were 15% and 20% for males and females, respectively. Prevalence rates of 12.5%, 13.7%, 12.7% and 25% were recorded for age groups of 10-20, 21-40, 41-60 and >60 years, respectively. The presence of S. pneumoniae based on the health status of the participants showed that the prevalence rates were 20% and 11.70% for clinically ill and clinically healthy individuals, respectively. The resistance profile to the test antibiotics were 22.9%, 22.9%, 11.4%, 100%, 100%, 34.3%, 34.3%, 100%, 54.3% and 77.1% respectively to perfloxacin, septrin, ciprofloxacin, amoxacilin, zinacef, gentamicin, erythromycin, ampliclox, streptomycin and rocephin. Ciprofloxacin was the most effective antibiotic followed by perfloxacin and septrin. Our isolates showed 100% multi-drug resistance and is a cause for concern.

The problem of bacteria resistance coupled with microorganisms being implicated as causative agents of many infectious diseases has led to the search for substances (phytochemicals) that can be used to stop the activity of these microorganisms and to reduce or eliminate their effect on the human population and to also curb the menace of bacteria resistance. This study aimed at carrying out phytochemical screening and antibacterial activity of whole plant crude extracts of Euphorbia hirta Linn against some clinical isolates. The selected clinical isolates (Escherichia coli, Pseudomonas fluorescens, Klebsiella pneumoniae, and Salmonella typhimurium) were identified using biochemical tests. The extraction of the whole plant of Euphorbia hirta with n-hexane, ethyl acetate, methanol, and water was done using reflux extraction technique. The screening for phytochemicals was carried out using standard methods while the determination of antibacterial activity of the extracts against selected clinical isolates was carried out using the agar well diffusion method. The results obtained show that phytochemicals such as flavonoids, terpenoids, alkaloids, steroids, tannins, saponins, phenols, and reducing sugars were present while cardiac glycosides were absent in all the extracts. The highest (21.33±0.33) antibacterial activity which is concentration-depended was recorded against Pseudomonas fluorescens using ethyl acetate extract while n-hexane extract has no antibacterial activity against any of the clinical isolates which possibly may be due to insufficient bioactive agents in the n-hexane extract. The study revealed that Euphorbia hirta contained phytochemicals that have antibacterial activity and can be very useful in drug development, and traditional and complementary medicine.

Published: June 2024

Irish potato (Solanum tuberusom) has contributed to human diet for thousands of years, first in the Andes of South America and then in the rest of the world. Potato is rich in potassium which reduces the risk of cardiovascular disease. Maca (Lepidium meyenii) contains macamides which are thought to have antioxidant effects. Prolonged storage of Irish potatoes is the stage at which good quality tubers are most difficult to maintain because of the transformations occurring at that time lead to quantitative changes in the composition of tubers. This work was designed to quantify potassium along aside with some minerals in Irish potato during storage with aqueous solution of maca flour. In the storage process, potatoes are affected by two negative factors, i.e., high (room) temperature, light and physiological activities in the tuber. The values obtained for Irish potato treated with aqueous maca 1:10 mL distilled water (MA1) and untreated potato as control (CTRL) respectively are potassium (173.85 and 93.67 mg/100 g), sodium (99.74 and 39.59 mg/100 g), magnesium (14.20 and 12.37 mg/100 g), phosphorus (56.00 and 39.00 mg/100 g), zinc (0.34 and 0.30 mg/100 g), manganese (0.39 and 0.33 mg/100 g) and copper (0.01and 0.01 mg/100 g). MA1 differs significantly (p < 0.05) from CTRL for potassium, sodium and magnesium phosphorus and zinc while there was no significant difference for manganese and copper. These results indicate that treating potato with low concentration of aqueous maca helps to retain minerals composition during storage.

Energi listrik merupakan energi yang paling dibutuhkan saat ini. Energi listrik sudah menjadi hal utama dalam seluruh segi kehidupan manusia karena itulah pemenuhan kebutuhan energi listrik menjadi sangat penting. Bentuk pembangkit energi yang menggunakan sumber terbaharukan menjadi hal utama yang dicari saat ini. Ada beberapa jenis energi terbaharukan yang dapat dijadikan sebagai sumber energi terbaharukan misalnya seperti energi surya, angin, dan air. Energi air merupakan salah satu sumber energi terbarukan yang pemanfaatannya tidak menimbulkan dampak pada lingkungan sekitar. Penggunaan kincir air merupakan salah satu pemanfaatan energi air menjadi pembangkit listrik mikrohidro (PLTMH). Namun tidak semua kincir air dapat dimanfaatkan pada head rendah dan debit yang besar. Dari bermacam macam jenis kincir jenis kincir air undershot memiliki konstruksi sederhana, dapat dimanfaatkan pada head rendah dan debit kecil namun memiliki efisiensi yang rendah. Tujuan dari penelitian ini untuk mengetahui performa terbaik dari penggunaan jumlah sudu, ketinggian, dan penggunaan bentuk sudu dari kincir air undershot. Dari penelitian ini diketahui bahwa penggunaan bentuk sudu setengah silinder dapat mengurangi gaya hambat dari air yang ada di belakang sudu yang dapat mengurangi gaya dorong hasil tumbukan air dengan bagian depan sudu. Hasilnya didapatkan bahwa performa terbaik dicapai pada penggunaan jumlah sudu setengah silinder dan jumlah sudu 16 buah sudu yaitu sebesar 2,19 %.

Teknologi Rapid Prototyping (RP) terus berkembang pesat dan memiliki peran penting di berbagai sektor. Salah satu metode yang digunakan dalam teknologi ini adalah Fused Deposition Modelling (FDM), yang melibatkan proses melelehkan bahan termoplastik dengan menggunakan mekanisme ekstruder. Mesin pencetak 3D tipe FDM mengendalikan pergerakan nozzle secara komputerisasi, yang menghasilkan berbagai arah gerakan, termasuk sejajar dengan sumbu x (0°), y (90°), dan juga diagonal (45°). Perbedaan dalam arah ini memiliki dampak pada karakteristik mekanis dari kekuatan lentur pada cetakan yang dihasilkan. Penelitian ini melibatkan pengujian tekan (Bending test) sesuai dengan standar ASTM D790 dengan menggunakan mesin pengujian Beste KJ-1065. Spesimen pengujian dibuat dalam tiga jenis yang berbeda, dengan pengaturan arah nozzle yang memiliki perbedaan sudut external infill angle offset dan internal infill angle offset, yaitu pada sudut 0° (sejajar sumbu X), 45° (sejajar diagonal), dan 90° (sejajar sumbu Y). Hasil penelitian menunjukkan bahwa arah nozzle pada mesin pencetak 3D tipe FDM juga mempengaruhi kekuatan tekan/lentur produk yang dihasilkan. Kekuatan tekan/lentur maksimum terbesar ditemukan pada produk dengan arah nozzle 0°, mencapai 65.21 MPa, sementara yang terendah terjadi pada produk dengan arah nozzle 90° dalam kondisi horizontal, mencapai 45.18 MPa.

Background The Distress Brief Intervention (DBI) is a new approach aimed at reducing distress and is embedded in Scotland’s suicide prevention and mental health strategies. People in distress can be referred to DBI by front-line healthcare and emergency service staff. DBI promises to make contact within 24 hours and offers people in distress 14 days of compassionate, community-based, and person-centred support. The development of NHS 24, a new specialist National Health Service Mental Health Hub (MHH) embedded in Scotland’s urgent care service created a new national route to access DBI. Protocol This study is a mixed-method evaluation of the impact of DBI on suicidal ideation, suicide attempts and self-harm in the immediate, short and longer term among people presenting in distress. Evaluation participants include adults who access DBI, DBI staff, individuals who have used NHS 24 MHH, and GPs. A combination of analysis of quantitative survey and linked administrative data, including a comparator group analysis, qualitative interview and focus group data will support understanding of whether and how DBI can reduce suicidal ideation, suicidal behaviour and self-harm among those presenting to front-line services in distress. A survey of General Practitioners and a review of existing literature will be used to model typical care pathways for individuals in distress and at risk of self-harm. Modelled resource use and costs will be explored. All data collected will be triangulated through a summative evidence synthesis to develop evidence-based insights and conclusions to inform policy and practice development. Discussion Understanding whether, how and why DBI has helped prevent future suicidal thoughts and behaviour in those with a history of suicidal risk will provide important insights into how the intervention can be further developed and optimised as a suicide prevention intervention.

Objective: Distraction osteogenesis (DO) is a well-known technique. The traditional method utilized the lengthening frequency of four times a day (QID). Many mechanical factors may affect the DO outcome. However, the effect of distraction frequency has not been proven clinically. Therefore, we aim to investigate whether the BID and QID lengthening frequency affect the healing index and complications of the DO.
Materials and Methods: We retrospectively reviewed patients who had undergone DO from 2010 – 2021. The patient was divided into BID and QID groups. Demographics, lengthening outcomes, and complications between the two groups were compared. We used the inverse probability of treatment weighting (IPTW) to determine the effect of treatment.
Results: The median healing index (HI) of the patients whose lengthening was done QID is 41.36 (IQR 32.72 - 67.68) days/cm, and BID is 49.12 (IQR 35.28 - 62.54) days/cm, which did not differ significantly. The Odds ratio of achieving HI < 45 days/cm for patients receiving QID lengthening compare to BID is 1.12 (95% CI 0.31-3.99, p = 0.862 ). The IPTW did not show a difference in average treatment effects between QID and BID lengthening. The rates of minor and major complications were not significantly different between the two groups (26.1% in QID group and 32.1% in BID group).
Conclusion: The frequency of QID and BID lengthening results in comparable HI and complications for patients who undergo DO. However, prospective research is needed to evaluate the effect of frequency differences in a clinical setting.

Objective: This study aims to develop and compare machine learning models (MLMs) for predicting venous thromboembolism (VTE) in patients undergoing surgery for spinal metastasis. The study evaluates the predictive capabilities of MLMs for preoperative and postoperative VTE within different time frames.
Materials and Methods: A total of 334 patients undergoing surgery for spinal metastasis were included, with a mean age of 57.6 years and 57.2% being male. The investigation assessed postoperative VTE prevalence within 30 and 90 days, with pulmonary embolism (PE) and deep vein thrombosis (DVT) rates at 20% and 80%, respectively. Key patient-related factors—age, body mass index, preoperative ambulatory status, albumin level, hemoglobin level, partial thromboplastin time, and operative time—were considered potential predictors of VTE.
Results: The postoperative VTE prevalence was 8.98% within 30 days and 13.47% within 90 days. Age, body mass index, preoperative ambulatory status, albumin level, hemoglobin level, partial thromboplastin time, and operative time emerged as significant VTE predictors. The gradient boosted tree algorithm was the best-performing MLM for predicting VTE within 90 days, with AUC values of 0.77 preoperatively and 0.71 postoperatively. For predicting VTE within 30 days, the support vector machine model was most effective, with AUCs of 0.72 preoperatively and 0.68 postoperatively.
Conclusion: Predictive analytics and MLMs effectively predict preoperative and postoperative VTE in patients undergoing surgery for spinal metastasis. Identified key factors and MLM performance metrics offer valuable insights for risk assessment and preventive measures in this patient population.
