One of those is chronic kidney disease patients before renal transplantation for pre-operative risk assessment. Aim of the work: to evaluate the difference in dobutamine stress echocardiography between those with chronic kidney disease (CKD) on regular dialysis and patient with no known history of chronic renal impairment. Methods: From February 2016 to January 2017, twenty consecutive chronic kidney disease patients prepared for renal transplantation without history suggestive of ischemic heart disease and 40 consecutive patients with without history of renal impairment. Their heart rate, dobutamine dose, atropine dose and adverse side effects were compared between the two groups. Results: Both groups were matched in age and risk factors. Peak heart rate (HR) (133.7±16.99 vs. 144.08±10.99 b/m, P=0.012), time to target heart rate was (17.75±3.29 vs. 13.05±2.95 min, p=0.001) and dobutamine and atropine doses were higher in chronic kidney disease group than other group. Adverse reactions present in both groups but more incidence in CKD group. Conclusion: Chronic kidney disease patients response to dobutamine when underwent dobutamine stress echocardiography showed delayed effect of it with more dobutamine and atropine doses needed and more adverse reactions including Bezold-Jarisch reflex.","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"4 1","pages":"164"},"PeriodicalIF":2.8,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41933668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

What was later discovered was the corona virus, with the high level of human mobility from one country to another as one of the factors that caused this type of virus to spread and infect citizens all over the world, including on March 2, the President of the Republic of Indonesia, Joko Widodo announced two a resident of Depok, West Java, tested positive for COVID-19. It has been 7 months since the Covid-19 pandemic has rolled on and it is not yet known when it will end, causing impacts not only on the health crisis but also on the difficult economy on all levels of society, causing despair and ending his life by hanging himself. Case report: A case was reported where the victim was a man with the initials DA, 28 years old, the work of an employee of PT Serdang Hulu. The victim was taken to the Pirngadi Hospital Medan by the police together with Visum et Repertum's request and carried out an examination of the body and an operation of the corpse at that time. Result: On external examination, a blue cloth was found with one end wrapped around the victim's neck as much as one loop with a slip knot, where the knot is located on the back of the head right in the midline of the body. There were lesions on the neck in the shape of the letter V which were slanted, blackish brown in color, hard touch, the front was below the Adam's apple, the left side was under the left ear, on the right side it was below the right ear, the injury ended on the back of the head on the right and left. Discussion: Based on anamnesis of investigators who went to the crime scene, the victim was an employee who was laid off due to the impact of the Covid-19 pandemic so that he did not have a job and was in debt. The victim ended his life by hanging himself. Conclusion: The victim was a male corpse, known, body length 16 6 cm, straight black hair and easily pulled out. From the results of external and internal examinations it was concluded that the cause of death of the victim was suffocation due to obstruction of air to enter the respiratory tract due to hanging death.","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2020-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48921970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nasal obstruction is the most frequent presentation to the otolaryngologist all over the world with septal deviation. Septoplasty is the common surgical procedure performed in nasal septal deviation. Physical examination, anterior rhinoscopy (AR) and nasal endoscopy (NE) are considered the gold standard tools to detect septal deviation. This study aimed to find out septal deviation with associated pathologies of nose and paranasal sinuses by using CT scan. Patients and Methods: 188 patients of nasal septal deviation were selected from 2015 to 2019. Age ranged in between 10 year to 70 year of age. CT scanning in both coronal, axial and sagittal sections had been done in all patients after proper history taking, physical examination, anterior rhinoscopy and nasal endoscopy. Endoscopic septoplasty alone and/or other ancillary procedures were performed in all 188 patients under general anesthesia. www.yumedtext.com | August-2020 | ISSN: 2582-5038 | https://dx.doi.org/10.46527/2582-5038.163","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44569338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-dimensional speckle tracking echocardiography is a reliable imaging modality that overcomes the limitations of Tissue Doppler imaging and allows a more accurate assessment of myocardial deformation at the global and regional levels. Objectives: The investigation aims to assess Left Ventricular functions in patients with hypertension and/or diabetes who have apparently preserved LV systolic function; using speckle tracking echocardiography, and correlate the findings with plasma Brain Natriuretic Peptide levels. Methods: Twenty healthy subjects were enrolled as a control group. Sixty patients with hypertension and/or diabetes were recruited and assembled as three equal groups, hypertensives, diabetics, and hypertensive-diabetics. 2D-STE was performed to assess LV longitudinal strain and strain rate. Plasma BNP levels were measured for all subjects. Results: Global systolic longitudinal strain was significantly reduced in patients compared to controls (P=0.001). It was more reduced in group 4. Global systolic SR was reduced in patients compared to controls, being more significantly reduced in groups 2 and 4 (P=0.001). Global early diastolic SR was reduced in patients compared to controls (P=0.001). Meanwhile, Global late diastolic SR values were higher among patients, especially groups 2 and 4 (P=0.001). BNP levels were significantly higher in group 4 compared to group 1 (P=0.000), group 2 (P=0.000), and group 3 (P=0.000). BNP levels and global systolic strain in group 4 were significantly correlated. Conclusion: LV systolic dysfunction was found among all patients groups, confirmed by the significant reduction in LV global longitudinal systolic SR. Hypertensive-diabetics exhibited lower global strain than patients with hypertension only and patients with diabetes only, even though their EF showed no apparent difference. Elevated BNP levels, being the highest among group 4, indicate the presence of ventricular dysfunction, even before chamber failure occurs.","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"4 1","pages":"131"},"PeriodicalIF":2.8,"publicationDate":"2020-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45135514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Numerous efforts have been made to reduce cardiovascular morbidity and mortality, especially in acute coronary syndrome (ACS). However, results are still not optimal. Much consideration is set on the revelation of new, conceivably modifiable cardiovascular risk factors. Vitamin D deficiency is proposed to be one such factor, and it might be related to an increased risk of cardiovascular diseases. Methods: We conducted a cross-section study on 475 patients undergoing elective coronary angiography, the participants were subjected to assessment of vitamin D level and major cardiovascular risk factors. The severity of CAD was assessed using the gensini score. Results: There were 352 (74.11%) patients, had a significant CAD. We found that vitamin D level had a significant negative correlation with the gensini score while diabetes and dyslipidemia had a significant positive correlation. The multivariate regression analysis showed that, vitamin D deficiency, diabetes, dyslipidemia, higher BMI, and ACS (p-value <0.05), were statistically significant predictors of a significant CAD. There were 184 (38.74%) patients, had vitamin D deficiency. Also, we found that diabetes and dyslipidemia had a significant negative correlation with vitamin D level. The multivariate regression analysis showed that diabetes and dyslipidemia were statistically significantly associated with low vitamin D levels (p-value 0.005 and 0.024 respectively). Conclusions: Vitamin D deficiency, diabetes, dyslipidemia, higher BMI, and ACS were statistically significant associated with severe CAD. Also, diabetes and dyslipidemia were statistically significant associated with vitamin D deficiency.","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"4 1","pages":"119"},"PeriodicalIF":2.8,"publicationDate":"2020-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42589815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yun, Dongdong Chen","doi":"10.11648/J.CCR.20200403.18","DOIUrl":"https://doi.org/10.11648/J.CCR.20200403.18","url":null,"abstract":"Paroxysmal supraventricular tachycardia (PSVT) is similar to coronary artery disease (CAD) in that it is often accompanied by chest pain, ST segment depression or elevated cardiac troponin in the electrocardiogram (ECG). Studies have shown that only 20%-40% of these patients are diagnosed with CAD by coronary angiography and even lower in foreign countries. Therefore, a noninvasive and simple method is urgently needed in practice to determine the high-risk population of PSVT patients with CAD, so as to avoid excessive examination and waste of medical resources. Cardiac troponin and ECG are favored in clinic because of their simple, economical and non-invasive detection methods. By analyzing the mechanism, it is concluded that elevated troponin and ST segment depression are of low predictive value for CAD diagnosis in PSVT patients, and it is necessary to further evaluate the risk factors for cardiovascular disease in these patients to determine whether coronary angiography is required. However, it is worth noting that ST segment depression in PSVT patients may be associated with coronary microcirculation lesions. Future research should also start from the pathogenesis, symptoms and characteristics of coronary microcirculation lesions to find more similarities and differences with PSVT combined with ST segment depression. This paper may contribute to a better understanding of troponin elevation and ST segment depression in PSVT patients.","PeriodicalId":50646,"journal":{"name":"ACM Sigcomm Computer Communication Review","volume":"4 1","pages":"127"},"PeriodicalIF":2.8,"publicationDate":"2020-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46955103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
