Limfadenopati dapat disebabkan oleh berbagai kondisi mulai dari keganasan, infeksi, autoimun, dan iatrogenik. Limfadenopati pada usia anak dan dewasa yang ukurannya tidak bertambah besar dalam kurun waktu kurang dari dua minggu atau lebih dari 12 bulan tidak bersifat neoplastik. Penelitian ini bertujuan mengetahui kesesuaian gambaran CT Scan leher dengan hasil biopsi aspirasi jarum halus (BAJAH) untuk membedakan limfadenopati leher yang jinak dan ganas. Penelitian ini dilaksanakan di Departemen Radiologi RS. Dr. Wahidin Sudirohusodo dan RS Universitas Hasanuddin Makassar mulai bulan Desember 2017 sampai Mei 2018. Sampel sebanyak 61 orang dengan rentang usia 4 - 82 tahun. Metode yang digunakan adalah observasional analitik dengan pendekatan cross sectional. Hasil penelitian menunjukkan gambaran keganasan limfadenopati leher pada CT Scan yang sesuai dengan BAJAH yaitu penyebaran ekstrakapsular, nekrosis sentral, bentuk bulat/lobulated dan margin irregular, sedangkan kalsifikasi dan ukuran tidak sesuai. Gambaran CT Scan limfadenopati leher yang jinak sesuai dengan hasil BAJAH yaitu tidak ada penyebaran ekstrakapsular, tidak ada nekrosis sentral, bentuk oval dan margin regular, sedangkan kalsifikasi dan ukuran tidak sesuai.

Lymphadenopathy can be caused by various conditions that were malignancy, infection, autoimmunity, and iatrogenic. In adults and children, lymphadenopathy whose duration is less than two weeks or more than 12 months but its size does not increase, that is not a neoplastic. The study aims to determine the relationship between CT Scan of neck image and the result of fine needle aspiration biopsy (FNAB) in distinguishing benign and malignant cervical lymphadenopathies. The research was conducted in Radiology Department of Dr. Wahidin Sudirohusodo and Universitas Hasanuddin Hospital Makassar from December to May 2018. The sample were 61 people aged form 4 – 82 years old. The observational analytic with cross sectional analytic were used in this study. The result revealed that image of malignant lymphadenopathies in CT Scan of neck were significantly related with FNAB results; extracapsular spread; central necrosis, lobulated or rounded forms with irregular margin, while calcification and size were not related. The image of benign lymphadenopathies in CT Scan of neck was related with FNAB results; no extracapsular spread, no central necrosis, oval formed with regular margin, while calcification and size were not related.

Aim. To study the impact of heart rate (HR) reduction with beta-blockers (BB) on left atrial (LA) function in hypertensive patients with paroxysmal or persistent mild symptomatic atrial fibrillation.Material and methods. In this open prospective trial we randomly assigned patients with hypertension, sinus rhythm, elevated heart rate (≥70 bpm), and recurrent atrial fibrillation (EHRA 2A or less) to receive BB with a target HR of less or greater than 70 bpm for at least 4 months. All the patients underwent an echocardiogram [left atrial (LA) function was assessed as emptying fraction]and applanation tonometry at baseline and after 4 months. Primary endpoint was median LA emptying fraction (LAEF) measurement at the end of the study.Results. 47 patients were randomized to group with a target HR of ≤70 bpm and 44 patients to >70 bmp. Among them 44 and 41 patients completed the study. Median follow up was 4.4 months. At the end of the study (4.5 months) median HR was 62 [60; 67] bmp in ≤70 group and 73 [72; 76] bpm in >70 group. Both groups received similar antihypertensive therapy and there were no intergroup differences in systolic and diastolic blood pressure. At the end of the study, patients in ≤70 group had significantly lower LAEF compared with >70 group (37% vs 42%; p=0.01). E’avg was lower and augmentation index was higher in ≤70 group as compared to >70. In regression analysis, after E’avg and augmentation index were included in the model, the association between LAEF and randomization group lost its significance.Conclusion. Beta blockers treatment with strict HR reduction (≤70 bpm) significantly reduced LA function as compared to lenient target HR (>70 bpm).

Aim. Determination of the possibility of reliable quantitative assessment of the coronary calcium index based on ultra-low-dose computed tomography (ultra-LDCT) which used in Moscow Lung Cancer Screening project.Material and methods. The study included the results of 254 ultra-LDCT studies conducted as part of the Moscow lung cancer screening project. For compare the parameters of coronary calcium on different images used 16 pairs of ultra-LDCT images with a slice thickness of 1 mm and CT images with a slice thickness of 3 mm, performed without ECG synchronization, performed with an interval of less than 10 days, as well as 18 pairs of ultra-LDCT with a slice thickness of 1 mm and CT with ECG synchronization with a slice thickness of 3 mm, performed on the same day after execution. Analysis of DICOM 3.0 standard images was performed. Quantitative indicators of coronary calcium in patients from lung cancer screening were analyzed, a comparative analysis of the calcium index for Agatstone, Volume, Mass, and using the CAC-DRS scale (assessment of the degree of calcification by scores from 0 to 3 and the number of affected arteries from 0 to 4 points) was performed.Results. Evaluation ultra-LDCT with a slice thickness in 1 mm and with a CT scan with slice thickness in 3 mm with and without ECG-synchronization for the presence of coronary calcium, and subsequent rating according to the index Agatston, Volume, Mass, as the total coronary calcium and for each coronary artery (right, left, left descending, left circumflex) received the complete data correlation (Pearson's - 1), with full correlation (Spearman's >0.9), with good rank correlations (>0,9). Compare qualitative (CAC-DRS V) and quantitative (CAC-DRS A) estimates on ultra-LDCT with CT with ECG synchronization in the same patients show a complete correlation of data was obtained (Pearson's formula - 1), with a complete correlation (Spearman's formula - 1).Conclusion. Coronary calcium which detected in lung cancer screening subjects should be included in the overall decision-making process for further routing of patients (cardiologist, interventional surgeon, pulmonologist, therapist). Ultra-LDCT is a method that has high diagnostic accuracy in detecting and evaluating the prevalence of coronary calcium in comparison with standard CT with and without ECG synchronization, as demonstrated in our study. Evaluation of coronary calcium according to ultra-LDCT without ECG synchronization used in screening, preferably with a 1 mm slice thickness. Despite the fact that the gold standard is CT with ECG synchronization with a 3 mm slice thickness, the diagnostic significance of ultra-LDCT which used in lung cancer screening is high in relation to detecting coronary artery calcification.

» The spinal column has a propensity for lesions to manifest in a multifocal manner, and identification of the lesions can be difficult.» When used to image the spine, magnetic resonance imaging (MRI) most accurately identifies the presence and location of lesions, guiding the treatment plan and preventing potentially devastating complications that are known to be associated with unidentified lesions.» Certain conditions clearly warrant evaluation with whole-spine MRI, whereas the use of whole-spine MRI with other conditions is more controversial.» We suggest whole-spine MRI when evaluating and treating any spinal infection, lumbar stenosis with upper motor neuron signs, ankylosing disorders of the spine with concern for fracture, congenital scoliosis undergoing surgical correction, and metastatic spinal tumors.» Use of whole-spine MRI in patients with idiopathic scoliosis and acute spinal trauma remains controversial.

Abstract
With the advent of information era, issues about video copyright continue to emerge. In the grey industrial chain of piracy, the film industry is a major disaster area so far. The current protection schemes for video copyright are inefficient and costly so that video industry still has to face the infringement. Research on a simple and efficient protection technology of video copyright is urgent. To address the inefficiency and irregularity of the current protection schemes for video copyright, this paper proposes a simple and efficient protection scheme for video copyright based on video zero-watermarking and blockchain. The results show that key-frames extraction and key-frames zero-watermarking based on NSCT-SVD in the proposed video zero-watermarking algorithm perform well and achieve low-cost protection for video copyright in practical environment. In addition, video zero-watermarking algorithm of proposed scheme works well with blockchain. Proposed scheme improves some extent on database centralization and evidential difficulties of traditional video zero-watermarking schemes, and it is more reliable, simpler and more effective than traditional video zero-watermarking schemes without blockchain.

Abstract
OBJECTIVE: This case-control study was conducted to analyze the association of periodontitis with risk indicators i.e. age, gender, education status, brushing habits and past dental visits in systemically healthy patients. METHODS: The study included total of 1097 systemically healthy, non-tobacco using patients with age ≥ 18 years that reported to periodontology department from year 2018. The demographic details and dental care pattern of the patients were extracted from the records of periodontology department, and their frequencies were formulated. The association of five study variables i.e. age, gender, education status, brushing habits and past dental visits was assessed using forward step-wise logistic regression analysis. RESULTS: Total of 471(42.9%) patients were diagnosed with periodontitis. Higher frequency of periodontitis was observed in patients who were male and ≥ 50 years of age. Regression analysis showed that the subjects with < 50 years of age, ≥ 12 years of education, regular brushing habits and regular past dental visits had greater odds of being safe from periodontitis. CONCLUSION: Since the population chosen for this research was systemically healthy, non-tobacco using individuals, a high prevalence (42.9%) of periodontitis was observed indicating the need to analyze the factors other than systemic conditions contributing in prevalence of periodontitis. Furthermore, a positive association between study variables and periodontitis was observed in this research, which will help the clinicians in prediction of periodontitis in systemically healthy, non-tobacco using individuals.

Authors: Han A lum , Kim Youngjon 
Published: July 2021

Abstract
Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a new nomenclature for non-alcoholic fatty liver. Fatty liver associated with metabolic dysfunction is increasing with obesity and has become a serious socioeconomic problem. Non-invasive testing to confirm MAFLD, such as the fatty liver index (FLI), can be used as an alternative method for diagnosing steatosis when imaging modalities are not available. To date, few studies have examined the effectiveness and validity of FLI for diagnosing MAFLD. Therefore, this study analyzed the effectiveness and validity of FLI for diagnosing MAFLD.Methods: The medical records of men and women aged 19 years or older who underwent abdominal computed tomography (CT) examination at the University Hospital Health Promotion Center from March 2012 to October 2019 were reviewed retrospectively. A comparative analysis between non-continuous variables was performed using the chi-squared test. The area under receiver operating characteristic (AUROC) curve was used to verify the effectiveness of FLI as a predictive index for MAFLD. Results: Analysis of the association between MAFLD and abdominal CT revealed that the sensitivity and specificity of FLI for diagnosing MAFLD were 0.712 and 0.713, respectively. The AUROC of FLI for the prediction of MAFLD was 0.776.Conclusion: Our study verified the accuracy of FLI for predicting MAFLD using CT. Additionally, FLI can be used as a simple and cost-effective tool for screening MAFLD in clinical settings

Published: July 2021

Abstract
Precise maximum temperature probability distribution information is indeed of accurately significance for numerous temperature uses. The purpose of this research to assess the appropriateness of these functions likelihood for evaluating the temperature models at different sites in southern part of Pakistan. The Kumaraswamy distribution function is used initially to approximation the models of maximum temperature. Compare the presentation of the Kumaraswamy distribution with twelve commonly used the probability functions. The consequences obtained show that the more effective functions are not similar across all sites. The maximum temperature features, quality and quantity of the noted temperature observation can be regarded as a factors that affect the presentation of the function. Similarly, the skewness of the noted maximum temperature observations may affect the precision of Kumaraswamy distribution. For the Hyderabad, Lahore and Sialkot sites, the Kumaraswamy distribution obtainable the topmost presentation, however for the Karachi, Multan stations, the generalized extreme value (GEV) distributions provided the best fit, respectively. According to the calculations, the Kumaraswamy distribution usually be regarded as a valid distribution because it runs 3 best fit sites and ranks 2 to 3 among the remaining sites. Though, the tight presentation of the Kumaraswamy and GEV and the flexibility of the Weibull distribution which has been usually verified, more evaluations of the presentation of the Kumaraswamy distribution are needed.

Published: July 2021

Abstract
Background: Artificial intelligence (AI) is rapidly gaining attention in medicine and in pathology in particular. While much progress has been made in refining the accuracy of algorithms, thereby increasing their potential use, we need to better understand how these algorithms will be used by pathologists, who will remain for the foreseeable future the decision-makers. The objective of this paper is to determine the propensity of pathologists to rely on AI decision aids and to investigate whether providing information on the algorithm impacts this reliance.Methods: To test our hypotheses, we conducted an experiment with within-subjects design using an online survey study. 116 respondent pathologists and pathology students participated in the experiment. Each participant was tasked with assessing the Gleason grade for a series of 12 prostate cancer samples under three conditions: without advice, with advice from an AI decision aid, and with advice from an AI decision aid with information provided on the algorithm, namely the algorithm accuracy rate and the algorithm model. Scores were computed by comparing the respondents’ scores with the “true” score at the individual-question level. A mixed effects logistic regression was used to analyze the difference in scores between the different conditions, controlling for the random effects of participants and images and to assess the interactions with Experience, Gender and beliefs towards AI.Results: Participant responses to the questions with AI decision aids were significantly more accurate than the control condition without aid. However, no significant difference was found when subjects were provided with additional accuracy rate and model information on the AI advice. Moreover, the propensity to rely on AI was found to relate to general beliefs on AI but not with particular assessments of the AI tool offered. Males also performed better in the No-aid condition but not in the AI-aid condition.Conclusions: AI can significantly influence pathologists and the general beliefs in AI could be major predictors of future reliance on AI by pathologists.

Abstract
ObjectivesTo explore men´s onset and burden of lower limb lymphedema (LLL) after radical prostatectomy (RP) with pelvic lymph node dissection.Patients and methodsA cross-sectional survey-based study was conducted nation-wide and web-based in Germany. Part 1 included 15 multidisciplinary compiled questions with three questions from Short Form 12 Health Survey (SF-12) and WHO activity recommendation, part 2 the validated German Lymph-ICF-Questionnaire (Lymph-ICF-LL). Subgroup comparisons and simple regression analyses were used to identify factors associated with therapy and burden of LLL, followed by multiple regression analyses to explain variance in impairment in the patients’ daily life.Results54 patients completed the survey. Median time of LLL-onset was reported with 2.0 (0.5-9.75) months after RP. 19 patients (35.2%) reported bilateral lymphedema, 28 (51.9%) the use of individually fitted compression stockings (CS), 25 (46.3%) of manual lymphatic drainage (LD) and 26 (48.1%) complete regression.The Lymph-ICF-LL revealed a higher total burden for patients with an active LLL compared to complete regression (total score: 25.5 vs. 11.9, p=0.01) specially for “physical function” (28.3 vs. 12.9, p=0.004) and “mental function” (26.2 vs. 6.7, p<0.001). In multiple linear regression analysis, a higher BMI (β=0.28), lower subjective general health (β=-0.48) and active lymphedema (β =0.28) were significant predictors of higher reported impairments in the Lymph-ICF-LL, accounting for 45.4% of variance.ConclusionMen with LLL after RP with PLND report a significant burden in daily life. Bbasic therapy needs to be offered early. Postoperative onset of LLL is variable, which should be considered when assessing complications after RP.

Abstract
Background: The variation and correlation among adiponectin, nesfatin-1, TNF-α and IL-6, which involve in the process from healthy to prediabetes and diabetes have not been elucidated. This study aims to investigate the roles of them in this process. Methods: 72 T2DM, 75 prediabetes and 72 healthy individuals were enrolled and serum adiponectin, nesfatin-1, TNF-α and IL-6 were tested with appropriate kit, and primary data were analyzed with correct method. Results: serum levels of each factor in prediabetes were between T2DM and healthy, and significant differences were found among them. TNF-α and nesfatin-1 levels in T2DM obviously different compared to prediabetes or healthy; IL-6 and adiponectin levels in the healthy group were significantly changed in contrast to prediabetes or T2DM. Correlation analysis found that in prediabetes, adiponectin was positively correlated with TNF-α (R=0.2939, P=0.0105) and IL-6 (R=0.3918, P=0.0005), and the relationship greatly strengthened when prediabetes accompanied by insulin resistant (TNF-α: R=0.7732, P<0.0001, IL-6: R=0.6663, P=0.0005). We also demonstrated that declined adiponectin (OR=6.238, P=0.019), nesfatin-1 (OR=2.812, P=0.01) and elevated TNF-α (OR=5.541, P=0.001) were risk factors for prediabetes towards diabetes. Conclusions: this research proved significant variations of adiponectin, nesfatin-1, IL-6 and TNF-α levels in the healthy, prediabetes and T2DM, suggesting a slow and gradual change during the progression of healthy condition toward diabetes via prediabetes.
