With the increasing development of EVs, the energy demand from theconventional utility grid increases in proportion. On the other hand, photovoltaic(PV) energy sources can overcome several problems when charging EVs from theutility grid especially in remote areas. This paper presents an effective photovoltaic stand-alone charging station for EV applications. The proposed charging station incorporates PV array, a lithium-ion battery representing the EV battery, and alead-acid battery representing the energy storage system (ESS). A bidirectionalDC-DC converter is employed for charging/discharging the ESS and a unidirectional DC-DC converter is utilized for charging the EV battery. The proposed controllers achieve maximum power extraction from the PV and regulate the DC-linkvoltage. It also controls the voltage and current levels of both the ESS and the EVduring the charging/discharging process. The study has been applied to two caseswith different power levels. Analysis, simulation, and implementation of the proposed system are presented. A 120 W laboratory prototype is carried out to verifythe system performance, experimentally. Design guides for higher power levelsare proposed to help in choosing the proper parameters of the converters. Boththe simulation and experimental results are matched and verify the highperformance of the proposed system.

Missed acute pulmonary embolism and sudden death: A case report

引用

Journal of Acute Disease 2019年第3期8卷 123-126页

作者： yasser Mohammed Hassanain elsayed Critical Care Unit Fraskour Central HospitalEgypt

Rationale: Pulmonary embolism is a severe cardiovascular disease. Acute pulmonary embolism is an extremely common and potentially the serious pattern of venous thromboembolic disease. Unfortunately, missed diagnosis of pulmonary embolism is lethal and common because of its non-specific symptoms and signs. Patient concerns: A 42-year-old male patient presented with acute chest pain that was treated as gastroesophageal reflux disease. Diagnosis: Suspected acute pulmonary embolism. Interventions: O2inhalation, urgent electrocardiography, and cardiopulmonary resuscitation. Outcomes: Deterioration and sudden cardiac death. Lessons: Physicians should pay much attention to the symptoms and signs of pulmonary embolism to reduce the rate of missed diagnosis.

AIM: To assess the diagnostic accuracy,of aminotransferase-to-platelet ratio index(APRI) alone and with antischistosomal antibody(Ab) in patients with hepatitis C virus(HCV) and schistosomiasis coinfection. METHODS: This retrospective study included medical records of three hundred and eighty three Egyptianmen patients who had undergone percutaneous liver biopsy between January 2006 to April 2014 in tertiary care hospital in Qatar for diagnosis or monitoring purpose were selected. Data of patients > 18 years of age were included in the study. The values of HCV RNA titer and antischistosomal antibody titer were also taken into consideration. Patients were excluded from the study if they had any other concomitant chronic liver disease,including; history of previous antiviral or interferon therapy,immunosuppressive,therapy,chronic hepatitis B infection,human immunodeficiency virus co-infection,autoimmune hepatitis,decompensated liver disease,hepatocellular carcinoma,prior liver transplantation,and if no data about the liver biopsy present. RESULTS: Median age of patients was 46 years. About 7.1% had no fibrosis,whereas 30.4%,37.5%,20.4%,and 4.6% had fibrosis of stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ respectively. In bivariate analysis,APRI score,levels of AST,platelet count and age of patient showed statistically significant association with liver fibrosis(P < 0.0001); whereas antischistosomal antibody titer(P = 0.52) and HCV RNA titer(P = 0.79) failed to show a significant association. The respective AUC values for no fibrosis,significant fibrosis,severe fibrosis and cirrhosis of APRI score were 63%,73.2%,81.1% and 88.9% respectively. This showed good sensitivity and specificity of APRI alone for grading of liver fibrosis. But the inclusion of anti-Schistosoma antibody did not improve the prediction of fibrosis stage. CONCLUSION: The study results suggest that noninvasive biochemical markers like APRI are sensitive and specific in diagnosing the degree of fibrosis and cirrhosis in patient
