Authors: Dressler Camillo Gabriela , Antonello Claudia Simone , Tomazzoni Gean Carlos
Published: September 2022

O enfrentamento da crise desencadeada pelo COVID-19 ressaltou a importância do olhar para como as pessoas lidam com momentos inesperados e estressantes. Nesse sentido, este trabalho busca analisar os níveis de autocompaixão e práticas de espiritualidade com foco em meditação de estudantes de graduação durante a pandemia do COVID-19, a fim de entender o quanto estes construtos podem ou não afetar positivamente a forma com que a crise é encarada entre os universitários. Realizou-se uma pesquisa survey com 650 estudantes de graduação, utilizando um questionário composto por questões sobre o perfil sociodemográfico e as práticas de bem-estar e meditação, além da Escala de Autocompaixão validada no Brasil por Souza e Hutz (2016). Os resultados apontam maior vulnerabilidade dos estudantes durante a pandemia e indicam a importância de práticas de espiritualidade, como a meditação, no enfrentamento do contexto de isolamento social. Os resultados ainda sugerem que a maior frequência de práticas de autocuidado e bem-estar está associada a maiores níveis de autocompaixão dos estudantes pesquisados. O estudo contribui para avanços sobre o papel das práticas de espiritualidade e autocompaixão como estratégias para o enfrentamento de situações altamente estressantes, desafiadoras e desagradáveis, como a pandemia de COVID-19.

Unified approach for tolerance analysis, synthesis, and compensator selection
Authors: Jain Prateek
Published: September 2022

Tolerancing is a necessary task for practical designs. The system Jacobian is utilized here for the three sub-tasks of tolerancing. The first is tolerance analysis, which is evaluation of the perturbed system. Second is tolerance allocation, also known as tolerance budgeting and more widely known as error budgeting. The automatic allocation of tolerances is tolerance synthesis. The algorithm described accomplishes this by fitting an orthotope inside an ellipsoid. Third is compensator selection. Metrics are presented that correlate with the looseness of the allocated tolerances and hence with the effectiveness of the compensator set, thus enabling identification of the most optimum combination of compensators.
Soliton phenomena in normal and anomalous dispersion regions in Er-doped mode-locked fiber lasers based on Cr2Si2Te6 saturable absorbers
Authors: Xu Nannan , Sun Shuo , Shang Xinxin , Zhang Huanian , Li Dengwang
Published: September 2022

Investigations of optical solitons have always been a hot topic due to their important
scientific research value. In recent years, ultrafast lasers based on
two-dimensional materials such as saturable absorbers (SAs) have
become the focus of optical soliton research. In this work, various
soliton operations are demonstrated in Er-doped fiber lasers (EDFLs)
based on SAs. First, a low-threshold passively
mode-locked EDFL with traditional soliton output is constructed, and
the pump threshold is as low as 10.1 mW. Second, by adjusting
the net dispersion of the cavity, stable dissipative soliton operation
can also be obtained. Traditional soliton mode-locked operation with
controllable Kelly sidebands from first order to fourth order is
realized by adjusting the pump power in a double-ended pumped
structure, and the SNR is as high as 55 dB. All results prove
that used as SA material has great
potential and wide application prospects in investigating optical
soliton operations in mode-locked fiber lasers with both normal and
anomalous dispersion.
Accurate phase detection in time-domain heterodyne SFG spectroscopy
Authors: Mirzajani Nasim , Keenan Clare L. , Melton Sarah R. , King Sarah B.
Published: September 2022

Heterodyne detection is a ubiquitous tool in spectroscopy for the simultaneous detection of intensity and phase of light. However, the need for phase stability hinders the application of heterodyne detection to electronic spectroscopy. We present an interferometric design for a phase-sensitive electronic sum frequency generation (e-SFG) spectrometer in the time domain with lock-in detection. Our method of continuous phase modulation of one arm of the interferometer affords direct measurement of the phase between SFG and local oscillator fields. Errors in the path length difference caused by drifts in the optics are corrected, offering unprecedented stability. This spectrometer has the added advantage of collinear fundamental beams. The capabilities of the spectrometer are demonstrated with proof-of-principle experiments with GaAs e-SFG spectra, where we see significantly improved signal to noise ratio, spectral accuracy, and lineshapes.

Published: September 2022

Photoacoustic endomicroscopy combined with ultrasound (PAEM-US) has been a long-standing expectation for gastrointestinal tumor examination. Here, we introduce a prototype disposable PAEM-US catheter and corresponding power interface unit, featuring catheter switchability, self-internal three-dimensional scanning, and system repeatability for gastrointestinal endoscopy. By utilizing high-fluence relays, cascade insertion loss of the optical waveguide is minimized to 0.6 dB with a high performance of power resistance, and a focus-customizable acousto-optic coaxial probe is designed for high-sensitivity optical-resolution photoacoustic imaging. Imaging capability was demonstrated with in vivo anatomical imaging at 30 frames per second. Imaging results showed co-registered microscopic visualization of the microvascular and stratification of the rat colorectum with lateral resolution of 18 μm and axial resolution of 63 μm, holding great potential in the clinical detection of gastrointestinal diseases.

Published: September 2022

Indonesia is a high-burden tuberculosis (TB) country with a wide case detection gap, exacerbated by the COVID-19 pandemic. We aimed to review the epidemiology of TB in a high-endemic setting of Indonesia before and during the implementation of health system strengthening activities for TB, including during the first two years of the COVID-19 pandemic. We analysed TB program data from Mimika District, Papua, Indonesia from 2014 to 2021. Health system strengthening activities to improve the programmatic management of TB were implemented from 2017 onwards. Activities included decentralization of TB services, training and mentoring of healthcare workers, improved screening for co-morbidities, and introduction and optimisation of Xpert testing in 2018. A total of 11,803 TB cases were notified to the Mimika District Health Office over eight years (2014–21). Between 2015 and 2019, there was a 67% increase in annual case notifications, an 89% increase in bacteriologically confirmed cases and the proportion of TB cases detected in primary care increased from 26% to 46%. In 2020, coinciding with the COVID-19 pandemic, investigation of people with presumptive TB fell by 38%, but the proportion of those tested with Xpert increased. TB case notifications decreased by 19% from 1,796 in 2019 to 1,461 in 2020, but then increased by 17% to 1,716 in 2021. Routine screening for co-morbidities (HIV, diabetes) among TB patients improved over time and was not affected by the pandemic. Treatment success overall was 71% and remained relatively unchanged. Loss to follow-up and death were 18% and 3.7% respectively. Improvements in TB case finding were observed over a period in which a range of health system strengthening activities were implemented. While COVID-19 had a negative impact on the TB program in Mimika District, there are encouraging signs of recovery. Further work is needed to improve TB treatment outcomes.

Authors: Kachingwe Mtisunge , Kazidule Kayambankadzanja Raphael , Kumwenda Mwafulirwa Wezzie , Chikumbanje Singatiya Stella , Baker Tim
Published: September 2022

Objective

To determine factors associated with in-hospital death among patients admitted to ICU and to evaluate the predictive values of single severely deranged vital signs and several severity scoring systems.

Methods

A combined retrospective and prospective cohort study of patients admitted to the adult ICU in a tertiary hospital in Malawi was conducted between January 2017 and July 2019. Predefined potential risk factors for in-hospital death were studied with univariable and multivariable logistic regression models, and the performance of severity scores was assessed.

Results

The median age of the 822 participants was 31 years (IQR 21–43), and 50% were female. Several factors at admission were associated with in-hospital mortality: the presence of one or more severely deranged vital signs, adjusted odds ratio (aOR) 1.9 (1.4–2.6); treatment with vasopressor aOR 2.3 (1.6–3.4); received cardiopulmonary resuscitation aOR 1.7 (1.2–2.6) and treatment with mechanical ventilation aOR 1.5 (1.1–2.1). Having had surgery had a negative association with in-hospital mortality aOR 0.5 (0.4–0.7). The predictive accuracy of the severity scoring systems had varying sensitivities and specificities, but none were sufficiently accurate to be clinically useful.

Conclusions

In conclusion, the presence of one or more severely deranged vital sign in patients admitted to ICU may be useful as a simple marker of an increased risk of in-hospital death.

Published: September 2022

In order to study the impact of inclusive finance on agricultural green development, This paper uses both static panel and dynamic panel (system GMM model) estimation methods to make empirical analysis of the impact of inclusive financial development on agricultural green development. The results both find that there is a significant positive correlation between the level of inclusive financial development, real GDP per capita, the proportion of the added value of agriculture, forestry, animal husbandry and fishery in GDP and agricultural green development. This paper puts forward some countermeasures and suggestions to promote agricultural green development, including vigorously developing inclusive finance, promoting economic growth, promoting the development of agriculture, forestry, animal husbandry and fishery, and increasing environmental protection expenditures.
Analysis of predicted factors for bronchoalveolar lavage recovery failure: An observational study
Authors: Shimoda Masafumi , Tanaka Yoshiaki , Morimoto Kozo , Abe Taro , Asaga Reina , Nakajima Kei , Okamura Ken , Yoshimori Kozo , Ohta Ken
Published: September 2022

Background

The bronchoalveolar lavage (BAL) recovery rate should generally be more than 30% for effective diagnosis. However, there have been no reports investigating a target bronchus for BAL, and the cause of BAL recovery failure is uncertain. Therefore, this study detected predictive factors for BAL recovery failure through investigations on a target bronchus for BAL by using a 3D image analysis system. Therefore, this study detected predictive factors for BAL recovery failure.

Materials and methods

We retrospectively collected data from 338 adult patients who underwent BAL procedures at Fukujuji Hospital from June 2018-March 2022. Factors correlated with the BAL recovery rate were detected. Furthermore, the patients were divided into the failure group (recovery rate <30%; 36 patients) and the success group (recovery rate ≥30%; 302 patients), and data were compared between the two groups by analysing the target bronchus by using a 3D image analysis system.

Results

The patients in the failure group were older (median 74.5 years old [IQR 68.0–79.0] vs. median 70.0 years old [IQR 59.0–76.0],p= 0.016), more likely to be male (n = 27 [75.0%] vs. n = 172 [57.0%],p= 0.048), more likely to have COPD (n = 7 [19.4%] vs. n = 14 [4.6%],p= 0.003), and more likely to perform a target site of BAL other than the middle/lingual lobe (n = 11 [30.5%] vs. n = 35 [11.6%],p= 0.004) than those in the success group. The area of the bronchial wall was positively related to the recovery rate (r = 0.141,p= 0.009), and the area of the bronchial wall in the failure group was lower than that in the success group (median 10.5 mm2[interquartile range (IQR) 8.1–14.6] vs. median 14.5 mm2[11.4–19.0],p<0.001).

Conclusion

The study shows that a thin bronchial wall, COPD, and a target site of BAL other than the middle/lingual lobe were identified as the predicted factors for BAL recovery failure. The weakness of the bronchial wall might cause bronchial collapse during the BAL procedure.

Authors: Song Do Kyeong , Hong Young Sun , Sung Yeon-Ah , Lee Hyejin
Published: September 2022

Background

Obesity and diabetes mellitus (DM) are both associated with cardiovascular disease. This study aimed to evaluate the association between body mass index (BMI) and stroke risk among patients with DM in Korea since relatively few studies have analyzed this area in detail.

Methods

We analyzed a total of 56,051 DM patients aged >30 years from the Korean National Health Insurance Service Cohort who had undergone at least one national health examination between 2002 and 2012. BMI scores were divided into six categories, while hazard ratios for stroke were calculated using Cox proportional hazard models.

Results

Overall stroke risk was positively associated with BMI for both men and women. For ischemic stroke, the risk was positively associated with BMI in women. However, for me, only patients with the highest BMI were at increased risk compared with patients with a BMI of 20–22.4 kg/m2. For hemorrhagic stroke, the risk was significantly associated with BMI with a U-shaped association in men. In women, only patients with the lowest BMI had an increased risk of hemorrhagic stroke compared with patients that have a BMI of 20–22.4 kg/m2.

Conclusion

BMI was positively associated with the overall risk of stroke among DM patients in Korea. The risk of ischemic stroke was higher in obese patients compared to overweight or normal-weight patients. However, the risk of hemorrhagic stroke was higher in slimmer patients compared with overweight or obese patients.
Social network and tourism consumption by households: Evidence from China
Authors: Sun Genjin , Qian Qi , Liu Yanxiu , Pu Bo , Wang Dan
Published: September 2022

Tourism consumption is not only an important means by which to improve residents’ sense of happiness but is also the main way to promote national economic development. In a traditional relational society such as China, it remains unclear how social network affects tourism consumption by households. Here, we evaluated the impact of the social network on tourism consumption by Chinese households using the data of 3254 samples from the China Family Panel Studies. The empirical results from the ordinary least square method showed that the social network promotes tourism consumption, which can be projected to increase by about 28% for every 1% increase in social network strength. This was further confirmed using the instrumental variable method to address the issue of endogenous social network formation, as well as other robustness checks. The impact of the social network on tourism consumption was heterogeneous. Compared with other residents, there were higher positive effects for high-income families, households with a head aged 35–44 years, urban families, and households in eastern China. The quantile regression results revealed that the impact of the social network was weakened with increasing tourism consumption by households. These results are crucial for policymakers, in that they could form good habits of tourism consumption and strengthen tourism market management, especially for the management of tourism negative events in the context of new media.
Phenotypic and transcriptomic responses of cultivated sunflower seedlings (Helianthus annuus L.) to four abiotic stresses
Authors: Barnhart Max H. , Masalia Rishi R. , Mosley Liana J. , Burke John M.
Published: September 2022

Plants encounter and respond to numerous abiotic stresses during their lifetimes. These stresses are often related and could therefore elicit related responses. There are, however, relatively few detailed comparisons between multiple different stresses at the molecular level. Here, we investigated the phenotypic and transcriptomic response of cultivated sunflower (Helianthus annuus L.) seedlings to three water-related stresses (i.e., dry-down, an osmotic challenge, and salt stress), as well as a generalized low-nutrient stress. All four stresses negatively impacted seedling growth, with the nutrient stress having a more divergent response from control as compared to the water-related stresses. Phenotypic responses were consistent with expectations for growth in low-resource environments, including increased (i.e., less negative) carbon fractionation values and leaf C:N ratios, as well as increased belowground biomass allocation. The number of differentially expressed genes (DEGs) under stress was greater in leaf tissue, but roots exhibited a higher proportion of DEGs unique to individual stresses. Overall, the three water-related stresses had a more similar transcriptomic response to each other vs. nutrient stress, though this pattern was more pronounced in root vs. leaf tissue. In contrast to our DEG analyses, co-expression network analysis revealed that there was little indication of a shared response between the four stresses in despite the majority of DEGs being shared between multiple stresses. Importantly, osmotic stress, which is often used to simulate drought stress in experimental settings, had little transcriptomic resemblance to true water limitation (i.e., dry-down) in our study, calling into question its utility as a means for simulating drought.

Studies on Phytoconstituents and Antioxidant Properties of Argemone mexicana Flower Extract
Authors: Marimuthu M. , Manikandan R.
Published: September 2022

In present study, the presence of bioactive compounds in A. mexicana flowers were analyzed and also evaluated the in vitro antioxidant properties of A. mexicana flowers. The flower extract showed the presence of alkaloids, flavonoids, saponins, tannins, phytosterol, triterpenoids, glycosides, anthraquinones and phenols. The total phenolic and flavonoid content were found to be 25.40 ± 1.20 μg gallic acid equivalents and 14.30 ± 0.20 μg quercetin equivalents, respectively. The carbohydrate and protein content was found to be 4.10 ± 0.24 mg/g and 2.10 ± 0.30 mg/g of the flower extract respectively. HPLC analysis of A. mexicana flower extract revealed the presence of biologically active components such as gallic acid, rutin, caffeic acid, quercetin and ferulic acid. A. mexicana flower extract exhibited 81.33% inhibition in DPPH assay, 85% in ABTS radical assay, 86% superoxide scavenging, 76% NO scavenging, 75% hydroxyl radical scavenging, 77% radicals indicating hydrogen peroxide radical scavenging potential of the flower extract. The antioxidant activity observed in the ethanolic extarct of A. mexicana flower may be related to the presence of significant amounts of total phenolics and flavonoids. Hence, A. mexicana flower extract could serve as natural sources of antioxidants and could be used in the treatment of free radical mediated diseases.

Published: September 2022

Addressing the large carbon footprint of conferences such as the UN Climate Change Convention Conference of the Parties (COP) will be important for maintaining public confidence in climate policy. Transparency is also a vital aspect of creating equitable outcomes in climate policies, as often those most likely to be affected or who are able to create change on the ground are often unable to attend in person because of the high financial costs as well as having a large carbon footprint. The selection of host locations for the regular meetings of the UN Climate Change Convention is based on a rotation in amongst the five UN regions, which for 2022 is Africa. Here, we present UCL’s own carbon footprint calculator and use it to weigh the benefits of certain modes of transport to the 2021 COP 26 in Glasgow, UK and the 2022 COP 27 to be held in Sharm El-Sheikh, Egypt. The calculator demonstrates the well-known carbon-efficiency of coach and rail over flights, but shows that these benefits are only partly mitigated in the case of COP 27 due to insufficient transport links from Europe to the conference location. However, we also highlight some of the benefits of hosting a COP in the global South, particularly in the context of climate justice. Incorporating these principles into the calculator, we invite visitors to COP this year to carefully consider their options for carbon offsetting and how the tenets of climate justice could be integrated into the carbon accounting framework.

Este artigo pretende relatar e analisar como se deu a execução do process drama “Caso Sônia” (baseado na obra “Valsa n. 6”, de Nelson Rodrigues) em duas turmas de graduação dentro da Universidade Federal da Grande Dourados (UFGD). Utilizando como base a dramaturgia rodrigueana, as autoras abordaram o tema do feminicídio em sala de aula, executando o process drama em uma turma da graduação em Artes Cênicas da Faculdade de Comunicação, Artes e Letras (FACALE); e na turma da Faculdade Indígena da mesma universidade (FAIND). Identificar a diversidade de conhecimento e entendimento que pode advir de um mesmo processo – empregado em turmas distintas – pode lançar novos olhares sobre as possibilidades e potencialidades de implicações do process drama, como foi o caso de ambas as experiências.
Summarizing Online Customer Review using Topic Modeling and Sentiment Analysis
Authors: Maarif Muhammad Rifqi
Published: September 2022

With the massive implementation of social media in various forms in various business domains, business or product owners have the opportunity to be able to take advantage of user review data that is available free of charge to evaluate the products they issue. User reviews on social media platforms, marketplaces, and e-commerce are User Generated Content (UGC) which is very useful for product owners to find out the extent of user preferences for their products. However, to be able to comprehensively read the data, the right technology is needed considering that the data is in the form of text in very large quantities. Reading one by one and then drawing conclusions is certainly not the right approach because it will take quite a lot of time. So, in this study, the researcher will use a text analysis-based approach, especially topic modeling and sentiment analysis to summarize user reviews in the comments or reviews column on the e-commerce platform. The case study used in this study is user reviews in the comments column on the Amazon site for the Lenovo K8 Note smartphone product. From the experiments carried out, the approach used can summarize the reviews written by quite many users in one summary that can be easily understood.

Published: September 2022

Covid-19 outbreak has led to many changes in social life, one of which is education. At present, classes have been replaced by digital media as a space for the development of students' skills and personalities. PAI learning is substantively a subject that emphasizes value cultivation, but we are now facing the problem of the Covid-19 pandemic, which has undermined values. As a result, it is critical to reintroduce disrupted values, particularly through moral education. The great Indonesian cleric, Haji Abdul Malik Karim Amrullah, served as the lens through which the research was conducted. This study uses a qualitative approach with the literature research method. The results of the study show that, from the perspective of Buya Hamka, values or morality are not only limited to students, but also by educators. PAI learning should have an important role in creating an ethical environment. Although technical education can change from offline to online learning, values and substances must be fixed and precise. In the end, values must be transformed into digital communities today through online education, especially through the subject of PAI.

Improving the quality of learning in madrasas depends on several factors. A very important factor, among others, is the application of madrasa culture towards quality improvement. Madrasa culture is a positive thing that must be maintained and implemented by all madrasa residents without feeling forced. One of the madrasa cultures that must be maintained is the issue of discipline, including the discipline of teachers in class attendance in the teaching and learning process. To improve the discipline of teachers can be pursued in various ways. This research is school action research. The action being tested is the application of reward and punishment for teachers at MAN Kendal. This research was carried out in two cycles, because from the results of research and data analysis, it turned out that in cycle II, teacher discipline in class attendance in the teaching and learning process increased and met the predetermined indicators of 75%. From the results of this study, it can be concluded that to improve teacher discipline in class attendance in teaching and learning activities can be done by applying reward and punishment to teachers.

This research aims to improve student learning activities and outcomes after implementing the Contextual Teaching and Learning (CTL) learning method in learning Arabic for class XI-MIPA at MAN Kendal. This research is classroom action research. The subjects of this study were 34 students of class XI-MIPA-6 in the academic year 2021/2022. The research procedure includes 3 stages, namely: the preparation stage, the implementation stage, and the report preparation stage. Cycles 1 and 2 include planning, implementing actions, observing, and reflecting. Students who score above the KKM or who score more than 75 in accordance with student learning mastery, namely before the action was taken, 21 students (62%), in Cycle 1 rose to 26 students (76%) and in Cycle 2 it increased to 30 students (88%). Applying the CTL learning method combined with group discussion interactions can generate student learning activities. The achievement of student learning activity scores in cycle 1 reached 81% (very high) and in cycle 2 it reached 84% (very high). Based on the results of the analysis of student activities in group discussion interactions and student learning outcomes in providing actions with the application of the CTL learning method, it was found that there was an increase in learning activities and student learning outcomes.

Objective. To analyze the state of autonomic regulation of the heart rate in patients with adolescent idiopathic scoliosis before the upcoming surgical treatment of spinal deformity.

Material and Methods. The study included 30 patients with adolescent idiopathic scoliosis who were admitted for surgical treatment from January to April 2021. There were 28 female and 2 male patients. The heart rate variability (HRV) registration was carried out on the VNS-micro vegetotester, with Poly-Spectrum.NET software, Neurosoft (Russia). The study was conducted for 5 minutes in the supine position and for 5 minutes after the active orthostatic test. Temporal and spectral indicators of heart rate were analyzed.

Results. When analyzing HRV at rest, an increase in the temporal indicators of the heart rate and the power of high-frequency wave oscillations was recorded, which indicates both an increased activity of autonomic regulation in general and the predominance of the regulatory influence o of the parasympathetic division of the autonomic nervous system. A decrease in all spectral components during an active orthostatic test and an increase in stress index values by 3.5 times indicate  a significant stress of regulatory systems.

Conclusion. Analysis of HRV in patients with adolescent idiopathic scoliosis at rest revealed increased autonomic activity with a predominant effect of the parasympathetic division of the autonomic nervous system. The state of exercise-induced energy deficit, registered after an active orthostatic test, indicates a significant preoperative stress of the regulatory systems and refers this category of patients to a group of increased risk of complications associated with hemodynamic instability.

Objective. To carry out a retrospective analysis of the restoration of the anterior and posterior vertebral body heights and the elimination of deformation of the anterior spinal canal wall caused by thoracic and lumbar spine injury, based on the data of spiral computed tomography (SCT).

Material and Methods. The study analyzed SCT data and case histories of 50 patients with thoracolumbar spinal cord injury operated on at different times after injury: up to 10 days – Group 1 and 11–30 days – Group 2. All patients underwent spinal reposition using a transpedicular device. The preoperative and postoperative SCT parameters were compared with the initial ones, which were calculated. The restoration of vertebral body heights and the elimination of deformation of the anterior spinal canal wall were compared in two groups depending on the distraction of interbody spaces and changes in the angle of segmental deformity.

Results. In Group 1, the anterior and posterior dimensions of the vertebral body were restored, on average, by 95.3 ± 1.9 and 96.9 ± 1.4 % of the initial height; in Group 2 – by 87.4 ± 4.2 and 96.6 ± 1.8 %, respectively. The maximum restoration of the anterior dimensions of the vertebral bodies was achieved with distraction of the anterior interbody spaces closer to 100 % of the original size in the first and second groups. The maximum recovery of the posterior dimensions of the vertebral bodies was obtained by distraction of the posterior interbody spaces by 97 % or more of the original dimensions. The maximum elimination of the displacement of bone fragments from the spinal canal was obtained by distraction of the interbody spaces to a distance close to 100 % of the initial one, and when the obtained angle of segmental deformity coincided with the initial one.

Conclusion. In the first 10 days after the injury, a greater percentage of the restoration of the anterior and posterior vertebral body heights and a decrease in the deformation of the anterior wall of the spinal canal were obtained. It was possible to maximally eliminate the deformation of the anterior wall of the spinal canal and restore the height of the anterior and posterior walls of the damaged vertebra by approaching the obtained dimensions of interbody spaces and the angle of segmental deformity to the initial ones.
Vertebral bone density in Hounsfield units as a predictor of interbody non-union and implant subsidence in lumbar circumferential fusion

Objective. To determine the values of Hounsfield units (HU) of the lumbar vertebrae predicting unsatisfactory radiological results of circumferential interbody fusion at the lumbar level.

Material and Methods. The data of patients who underwent a single-level decompression and stabilization intervention at the L4–L5 or L5–S1 level for degenerative diseases of the spine were analyzed. The CT images of the lumbar spine were assessed before surgery with the measurement of HU values of the vertebral bodies at the intervention level, as well as CT images one year after surgery to evaluate the degree of interbody block formation and subsidence of the cage. Three groups of patients were distinguished: patients with a formed interbody bone block and without cage subsidence (control group), patients with failed fusion and patients with cage subsidence.

Results. The study presents CT data of 257 patients. The incidence of non-union was 32.3 % (83/257), and of cage subsidence – 43.6 % (112/257). The proportion of patients with reduced bone mineral density (BMD) was 26.1 % (67/257). Patients with non-union and subsidence had higher ODI scores (p = 0.045 and p = 0.050, respectively) compared to controls. The presence of fusion failure and subsidence is associated with reduced BMD (p < 0.05), HU values of vertebrae (p < 0.05), and higher ODI score (p < 0.05). According to the ROC analysis, threshold HU values were determined equal to 127 HU, 136 HU and 142 HU for the L4, L5, S1 vertebral bodies, respectively. Upon reaching these values, the risk of a combination of fusion failure and subsidence increases significantly (p = 0.022).

Conclusions. Patients with non-union and cage subsidence have less satisfactory clinical outcomes. The HU values of the vertebral bodies equal to 127 HU, 136 HU and 142 HU for the L4, L5, and S1, respectively, are advisable to use in practice to predict non-union and subsidence after a single-level decompression and stabilization intervention at the lower lumbar levels.
