Abstract Background and Aims Coronavirus disease 2019 (COVID-19) has affected the care and outcomes of patients treated with dialysis worldwide. Patients on hemodialysis (HD) are at extremely high risk to develop COVID-19 because of their multiple co-morbidities and immunosuppression. We report throw this work the experience of our unit of HD with the covid-19 infection and its outcomes on our patients. Method We conducted a prospective study since the beginning of the pandemic. We have collected 26 HD patients reached of COVID 19 disease. Results The sex ratio of our population was equal to 1,36 with female predominance. The mean age of our patients was 61, 31 ±14,17 years. The co-morbidities noted among these patients were respectively hypertension, diabetes, heart diseases and obesity in 19, 17, 10 and 10 cases. The causal nephropathy was respectively diabetic, undetermined, glomerular and interstitial nephropathy in 13, 9, 2 and 2 cases. The major symptoms associated to the COVID 19 were respectively dyspnea, cough, asthenia, fever and chills, digestive manifestations, chest pain in 22, 19, 19, 15, 10, and 6 cases. 7 patients have been exposed to covid-19 infested person. Symptoms appeared within an average of 4,3 ± 2 days. Oxygen saturation was less than 92% in 65% of the cases during hospitalization. 84% of the patients are hospitalized including one among them who required the stay in a resuscitation unit and intubation. The scannographic lesions of covid were estimated to more than 50% in 8 cases and less than 50% in 4 cases. A biological inflammatory syndrome has been noted in all of the patients with a mean CRP at 117+/-127 mg/l and the mean leucocytes count at 10248±6592 elt/mm3. Lymphopenia was noted in 14 cases with lymphocytes count less than 1500 elt/mm3. The ratio of neutrophils / lymphocytes was more than 2,5 in 12 cases. The treatment was based on oxygen, corticosteroids, antibiotics, vitamins and anticoagulation for hospitalized patients (22 patients). The mean number of HD sessions realized per patient during hospitalization was 4 ± 2,3 HD sessions. The perdialytic complications noted were alteration of the state of consciousness in 3 cases and heart failure in 5 cases. The outcomes of our patients were marked by death in 38% and a recovery in 62% of the patients. Thus, the forms observed in our series are respectively moderate, severe, pauci-symptomatic and asymptomatic in 12, 10, 2 and 2 cases. Conclusion We highlight throw this study the severe consequences of COVID-19 on HD patients in whom mortality reached 38%. Until the pandemic is controlled and a vaccine or a treatment are valid, we highlight the importance of the compliance with confinement and develop home dialysis among our population.

The heart failure (HF) is one of the greatest problems of public health with increasing epidemiological importance. In the present study we analyzed a population of 299 patients, consecutively admitted to hospital, whose diagnosis of HF was verified retrospectively. In our analysis we considered underlying heart diseases, comorbidities, ejection fraction, presence of atrial fibrillation and pleural effusion, values of NT pro-BNP and causes of destabilization precipitating HF. The mean age of our population was 81 years. Patients with preserved systolic function were 145 (61% of the total, 59 male and 86 female). 166 patients (69% of the total) had hypertensive heart disease and 211 had hypertension (88% of the total). Patients with pleural effusion were 108 (46% of total). In the total population 102 patients (43%) had from 3 to 5 comorbidities, 169 patients (71%) had at least 2 comorbidities and only 4 patients (1.7%) had no comorbidities. The collected data highlight the complexity of patients with HF, often due to advanced age and a high number of comorbidities.

SummaryTwenty-four dogs (27 limbs) were evaluated after surgery for correction of forelimb angular limb deformities. Partial ulnar ostectomies or definitive corrective osteotomies were performed depending upon the age of the dog. According to owner assessment nine of fourteen limbs were considered functionally good, or excellent, after partial ulnar ostectomies. Younger dogs appeared to have better functional results after dynamic correction with the mean age at surgery of dogs with good to excellent results being 6.5 months contrasted to the mean age at surgery of dogs with fair to poor results being 9.75 months. Ten of fourteen limbs were considered functionally good or excellent after definitive corrective osteotomy. One dog had definitive osteotomy after partial ulnar ostectomy in order to further correct a residual angular deformity. However, 58% of the limbs with radiographic follow-up had signs of degenerative joint disease (DJD). There were not significant differences between neither degree of angulation remaining after surgery and the functional result nor the degree of angulation remaining after surgery and the development of DJD. A prospective study is warranted to more objectively assess the efficacy of surgical correction of angular limb deformities in dogs.Twenty-four dogs were evaluated after surgery for correction of forelimb angular limb deformities. The results are described.

Background: End-stage heart failure (HF) is refractory to current standard medical therapy, and the number of donor hearts is insufficient to meet the demand for transplantation. Recent studies suggest autologous stem cell therapy may regenerate cardiomyocytes, stimulate neovascularization, and improve cardiac function and clinical status. Although human fetal-derived stem cells (HFDSCs) have been studied for the treatment of a variety of conditions, no clinical studies have been reported to date on their use in treating HF. We sought to determine the efficacy and safety of HFDSC treatment in HF patients.Methods and Results: Direct myocardial transplantation of HFDSCs by open-chest surgical procedure was performed in 10 patients with HF due to nonischemic, nonchagasic dilated cardiomyopathy. Before and after the procedure, and with no changes in their preoperative doses of medications (digoxin, furosemide, spironolactone, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, betablockers), patients were assessed for New York Heart Association (NYHA) class, performance in the exercise tolerance test (ETT), ejection fraction (EF), left ventricular end-diastolic dimension (LVEDD) via transthoracic echocardiography, performance in the 6-minute walk test, and performance in the Minnesota congestive HF test. All 10 patients survived the operation. One patient had a stroke 3 days after the procedure, and although she later recovered, she was unable to perform the follow-up tests. Another male patient experienced pericardial effusion 3 weeks after the procedure. Although it resolved spontaneously, the patient abandoned his control tests and died 5 months after the procedure. An autopsy of the myocardium suggested that new young cells were present in the cardiomyocyte mix. At 40 months, the mean (SD) NYHA class decreased from 3.4 0.5 to 1.33 0.5 (P = .001); the mean EF increased 31%, from 26.6% 4% to 34.8% 7.2% (P = .005); and the mean ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% increase in metabolic equivalents, from 2.46 to 5.63) (P < .0001); the mean LVEDD decreased 15%, from 6.85 0.6 cm to 5.80 0.58 cm (P < .001); mean performance in the 6-minute walk test increased by 43.2%, from 251 113.1 seconds to 360 0 seconds (P = .01); the mean distance increased 64.4%, from 284.4 144.9 m to 468.2 89.8 m (P = .004); and the mean result in the Minnesota test decreased from 71 27.3 to 6 5.9 (P < .001).Conclusion: Although these initial findings suggest direct myocardial implantation of HFDSCs is feasible and improves cardiac function in HF patients at 40 months, more clinical research is required to confirm these observations.

Purpose: i) To determine the relationship between the cardiac biomarkers ST2 and NT-proBNP with ejection fraction (EF) in heart failure (HF) patients. ii) Assess whether a superiority existed between the aforementioned cardiac markers in diagnosing the HF with reduced EF. iii) Determine the efficacy of both biomarkers in predicting a 30-day cardiovascular event and rehospitalization in patients with HF with reduced EF iv) To assess the influence of age, gender, BMI, anaemia and renal failure on the ST2 and NT-proBNP levels. Design and Methods: A prospective double-blind study was conducted to obtain data from a sample of 64 cardiology patients. A blood sample was collected to test for ST2 and NT-proBNP. An echocardiogram (to obtain EF value), electrocardiogram and questionnaire were also obtained. Results: Of the 64 patients enrolled, 59.4% of the population had an EF less than 40%. At the end of the 30- day period, 7 patients were warded, 37 were not warded, one died and 17 were non respondent. Both biomarkers were efficacious at diagnosing HF with a reduced EF. However, neither of them were efficacious in predicting 30-day rehospitalization. The mean NT-proBNP values being: not rehospitalized (2114.7486) and 30 day rehospitalization (1008.42860) and the mean ST2 values being: not rehospitalized (336.1975), and 30-day rehospitalization. (281.9657). Conclusion: Neither ST2 or NT-proBNP was efficacious in predicting the short- term prognosis in HF with reduced EF. Both however were successful at confirming the diagnosis of HF in HF patients with reduced EF.

Background: Cardiovascular diseases are the leading cause of death in patients with chronic renal failure. When a patient undergoes dialysis, making AVF or AVG causes cardiovascular events. Understanding the relationship between complications: hypertension, heart failure, AVF or AVG (formation time, position, diameter) helps us monitor, detect, prevent and treatment of complications to limit the risk of death in patients with dialysis. Objective: Relationship between cardiovascular diseases and anatomosis of arteriovenous fistular in patients with regularly hemodialysis at Cho Ray Hospital. Methods: A cross-sectional study was conducted at Cho Ray Hospital from 2015 to 2016. The survey some cardiovascular diseases are done by clinical examination, tests for diagnostic imaging such as X-ray, electrocardiogram and echocardiogram: heart and diameter of anastomosis AVF, AVG. Results: The study population included 303 patients with chronic renal failure who were dialysis. Of which, patients aged 25-45 accounted for the highest proportion (43.9%). The proportion of male and female patients was similar (48.5% and 51.5% respectively). The mean value of systolic blood pressure on patients made AVF, AVG less than 12 months is higher than patients made AVF, AVG over 12 months, and there is negative correlation (r = -0.43) between AVF, AVG and systolic blood pressure (p <0.05). The mean value of diastolic blood pressure on patients made AVF, AVG less than 12 months is lower than patients made AVF, AVG over 12 months, and and there is positive correlation (r = -0.43) between AVF, AVG and diastolic blood pressure (p <0.05) (p <0.05). The prevalence of patients with heart failure made AVF, AVG over 12 months is higher than that of the under 12 months group, there is a negative correlation (r = - 0.43) between AVF, AVG diameter and EF index (p <0.05). Conclusion: It is important to note the diameter of anastomosis AVF, AVG in patients with chronic renal failure dialysis to limit cardiovascular complications, especially heart failure. Key words: Chronic kidney disease, hemodialysis.

The Relationship

Recently, numerous studies have found that particulate matter (PM) exposure is correlated with increased hospitalization and mortality from heart failure (HF). In addition to problems with circulation, HF patients often display high expression of cytokines in the failing heart. Thus, as a recurring heart problem, HF is thought to be a disorder characterized in part by the inflammatory response. In this review, we intend to discuss the relationship between PM exposure and HF that is based on inflammatory mechanism and to provide a comprehensive, updated evaluation of the related studies. Epidemiological studies on PM-induced heart diseases are focused on high concentrations of PM, high pollutant load exposure in winter, or susceptible groups with heart diseases, etc. Furthermore, it appears that the relationship between fine or ultrafine PM and HF is stronger than that between HF and coarse PM. However, fewer studies paid attention to PM components. As for experimental studies, it is worth noting that coarse PM may indirectly promote the inflammatory response in the heart through systematic circulation of cytokines produced primarily in the lungs, while ultrafine PM and its components can enter circulation and further induce inflammation directly in the heart. In terms of PM exposure and enhanced inflammation during the pathogenesis of HF, this article reviews the following mechanisms: hemodynamics, oxidative stress, Toll-like receptors (TLRs) and epigenetic regulation. However, many problems are still unsolved, and future work will be needed to clarify the complex biologic mechanisms and to identify the specific components of PM responsible for adverse effects on heart health.
