Published: July 2021

A tomografia computadorizada (TC) é um método de diagnóstico por imagem com altas doses de radiação ionizante entregue ao paciente – de 100 a 500 vezes as doses em procedimentos convencionais por raios X. No caso de pacientes pediátricos, a preocupação com as doses de radiação é maior, devido à grande expectativa de vida e ao fato de eles serem mais radiossensíveis que adultos. Sendo assim, optou-se por realizar o estudo com pacientes pediátricos, de 0 a 2 anos, submetidos a exames de TC de crânio. objetivo deste trabalho é apresentar a avaliação de um processo de otimização de protocolos de crânio pediátrico em tomografia computadorizada, avaliando parâmetros de qualidade de imagem e diminuição de dose, sem perda na qualidade das imagens. Foi verificado o índice CTDIvol em quinze amostras de exames de crânio, assim como parâmetros de aquisição das imagens, no referido protocolo. A partir destes dados, foram desenvolvidos cinco protocolos experimentais e analisaram-se as razões contraste-ruído das imagens produzidas. Utilizando como métrica de qualidade a figura de mérito (FOM) para análise da qualidade em comparação com os níveis de CTDIvol, concluiu-se que, embora o índice de dose do protocolo atual esteja condizente com a recomendação da AAPM, de 29 mGy, é possível reduzir o índice de CTDIvol, para 18 mGy – ou seja, uma redução de 40% do CTDIvol com relação à recomendação da AAPM e de 23% em relação ao protocolo atual. Com os parâmetros de aquisição estudados, constatou-se uma redução na qualidade das imagens, conforme a análise do FOM. Sendo assim, sugere-se a utilização de algoritmos de redução do ruído, ou seja, filtros de reconstrução, para não haver prejuízo da qualidade diagnóstica das imagens.

Remaining spine deformity after revision surgery for pelvic reconstruction and spinopelvic fixation: illustrative case
Authors: Ito Takayuki , Fujibayashi Shunsuke , Otsuki Bungo , Tanida Shimei , Okamoto Takeshi , Matsuda Shuichi 
Published: July 2021

BACKGROUND
Pelvic deformity after resection of malignant pelvic tumors causes scoliosis. Although the central sacral vertical line (CSVL) is often used to evaluate the coronal alignment and determine the treatment strategy for scoliosis, it is not clear whether the CSVL is a suitable coronal reference axis in cases with pelvic deformity. This report proposes a new coronal reference axis for use in cases with pelvic deformity and discusses the pathologies of spinal deformity remaining after revision surgery.

OBSERVATIONS
A 14-year-old boy who had undergone internal hemipelvectomy and pelvic ring reconstruction 2 years prior was referred to our hospital with severe back pain. His physical and radiographic examinations revealed severe scoliosis with pelvic deformity. The authors planned a surgical strategy based on the CSVL and performed pelvic ring reconstruction using free vascularized fibula graft and spinopelvic fixation from L5 to the pelvis. After the procedure, although the patient’s back pain was relieved, his scoliosis persisted. At the latest follow-up, his spinal deformity correction was acceptable with corset bracing. Therefore, the authors did not perform additional surgeries.

LESSONS
The CSVL may not be appropriate for evaluating coronal alignment in cases with pelvic deformity. Accurate preoperative planning is required to correct spinal deformities with pelvic deformity.

The Knoevenagel condensation reaction between dehydracetic acid and aromatic aldehydes is described in this work. The reaction is carried out directly between dehydroacetic acid and aromatic aldehydes in the presence of organic bases. The optimal conditions for the Knoevenagel reaction based on dehydroacetic acid and various aldehydes were determined. Twenty-one chalcones with substituents of different nature were synthesized. The composition and structure of the obtained compounds were determined. All characteristic signals of chalcones are present in the 1H NMR spectra of the obtained compounds registered in CDCl3 and DMSO-d6: OH groups in the range of 18.7–16.5 ppm, CH proton – 6.3–5.9 ppm, and methyl group of the pyran cycle 2.3–2.2 ppm. The corresponding signals of methine protons and aryl substituents are also present in the spectra. The most sensitive to solvent changes is the OH proton bound by an intramolecular hydrogen bond to the carbonyl group of the pyran ring. Signals in DMSO are usually shifted by 0.1–1.0 ppm in a stronger field compared to CDCl3 for dehydroacetic acid and chalcones based on it. CH proton signals are shifted by approximately 0.3 ppm in a weaker field, and the signals of the protons of the methyl group are almost insensitive to the solvent. The optical properties of obtained compounds were investigated in DMF, MeOH, MeCN. The synthesized chalcones absorb light in the visible range 330–490 nm with molar extinction coefficients of 3.5–4.5. The solvatochromic effects for most of them are weak – the position of the maximum changes by less than 10 nm. The electron-donor substituents in the phenyl ring (-NMe2 and -NEt2) shift the absorption ma­ximum bathochromically by almost 100 nm compared to others in all investigated solvents.

The aim of this article was to analyze the effect of acceptance and management of political parties in Indonesia. To understand this study's problem, study the data we have done, including reviewing ten academic findings from international publications, observing and documenting data related to this topic. After the data was collected, we were then provided with analysis, including text analysis, description, coding, and immersion results. Every text is in a language, so we use a translation application to help us understand Indonesian. To determine whether the data constitutes a valid and reliable study finding, we review it and make sure we have answered the study questions. So the results we can report that the RSD framework has become a conceptual framework for the development of research skills for academic and educational needs. The result show that The sources of revenue for political party funds in Indonesia based on Law Number 2 of 2011, come from membership fees, donations, and state assistance. However, the majority of political party funding sources come from donors, including individual donors and business entities. There are still differences in the financial structure of political parties in the law and in daily political practice, indicating that regulations that discuss party funding (Law No. 2 of 2008 and Law No. 2 of 2011) fail to encourage political parties to raise funds to meet their operational needs

Background: The consequence of valve malposition (VM) during transcatheter aortic valve replacement (TAVR) can be severe, but the determinants of VM with self-expandable TAVR have not been thoroughly evaluated. We aimed to investigate the anatomical predictors of VM during self-expandable TAVR.Methods: In this multicenter retrospective study, TAVR was performed using the Venus A-Valve. The baseline, computed tomography, and procedural characteristics along with clinical outcomes were collected. Multivariate logistic regression model and receiver operating characteristic (ROC) curve analyses were performed.Results: A total of 84 consecutive patients (23 with VM) were included. Stepwise regression showed that annulus perimeter/left ventricular outflow tract perimeter (AL ratio) and sinotubular junction (STJ) height were predictors of VM. The ROC curve indicated a moderate strength of AL ratio [area under the curve (AUC) 0.71, cutoff 0.96] and a weak strength of STJ height (AUC 0.69, cutoff 23.8 mm) to predict VM. The combination of both predictors revealed a higher predictive value of VM (AUC 0.77). In multivariate analysis, AL ratio &lt;0.96 [odds ratio (OR) 3.98, p = 0.015] and STJ height ≥23.8 mm (OR 4.63, p = 0.008) were strong independent predictors of VM. The presence of both predictors was associated with a very high risk of VM (OR 10.67, p = 0.002). The rate of moderate-to-severe paravalvular regurgitation was higher in patients with VM at 30 days (26.1 vs. 4.9%, p = 0.011).Conclusions: A conical left ventricular outflow tract and tall aortic sinuses were strong anatomical predictors of VM during self-expandable TAVR.

Objective: To explore the preferred test to screen for pulmonary arteriovenous malformations (PAVMs) and to predict the probability of interventional embolization.Methods: We performed a retrospective observational study evaluating patients with idiopathic PAVMs from 2009 to 2019. After clinical evaluation, a total of 105 patients were studied, including 71 patients with positive digital subtraction pulmonary angiography (DSPA) findings and 34 with negative DSPA findings. The following patient data were assessed: blood test, chest radiograph, transthoracic contrast echocardiography (TTCE), and DSPA findings.Results: The majority of patients with idiopathic PAVMs were female (66.2% with positive DSPA findings). We found a good κ-coefficient of 0.77 with strong consistency for inter observer agreement concerning the pulmonary right-to-left shunt (RLS) grade on TTCE, which was superior to conventional chest radiographs. The positive predictive value (PPV) of the radiographic features for PAVMs on DSPA was 0.83 (95% CI 0.64–1.0) and 0.44 for the possibility of embolization (95% CI 0.19–0.70). The PPV of the shunt grade of PAVMs on DSPA was 0.14 (95% CI 0.01–0.29) for grade 1, 0.74 (95% CI 0.60–0.88) for grade 2, and 0.97 (95% CI 0.92–1.0) for grade 3. The PPVs of pulmonary shunt grades 2 and 3 on TTCE for the possibility of embolization for PAVMs were 0.21 (95% CI, 0.05–0.36) and 0.87 (95% CI, 0.79–0.99), respectively.Conclusion: TTCE is the preferred screening test for PAVMs. The pulmonary RLS grade on TTCE not only identifies the likelihood of PAVMs but also predicts the probability for embolization.

Background: Patients with acute type A aortic dissection are usually transferred to the intensive care unit (ICU) after surgery. Prolonged ICU length of stay (ICU-LOS) is associated with higher level of care and higher mortality. We aimed to develop and validate machine learning models for predicting ICU-LOS after acute type A aortic dissection surgery.Methods: A total of 353 patients with acute type A aortic dissection transferred to ICU after surgery from September 2016 to August 2019 were included. The patients were randomly divided into the training dataset (70%) and the validation dataset (30%). Eighty-four preoperative and intraoperative factors were collected for each patient. ICU-LOS was divided into four intervals (&lt;4, 4–7, 7–10, and &gt;10 days) according to interquartile range. Kendall correlation coefficient was used to identify factors associated with ICU-LOS. Five classic classifiers, Naive Bayes, Linear Regression, Decision Tree, Random Forest, and Gradient Boosting Decision Tree, were developed to predict ICU-LOS. Area under the curve (AUC) was used to evaluate the models' performance.Results: The mean age of patients was 51.0 ± 10.9 years and 307 (87.0%) were males. Twelve predictors were identified for ICU-LOS, namely, D-dimer, serum creatinine, lactate dehydrogenase, cardiopulmonary bypass time, fasting blood glucose, white blood cell count, surgical time, aortic cross-clamping time, with Marfan's syndrome, without Marfan's syndrome, without aortic aneurysm, and platelet count. Random Forest yielded the highest performance, with an AUC of 0.991 (95% confidence interval [CI]: 0.978–1.000) and 0.837 (95% CI: 0.766–0.908) in the training and validation datasets, respectively.Conclusions: Machine learning has the potential to predict ICU-LOS for acute type A aortic dissection. This tool could improve the management of ICU resources and patient-throughput planning, and allow better communication with patients and their families.
