IntroductionSudden cardiac death (SCD) is the most lethal manifestation of heart disease. In an Indian study the SCDs contribute about 10% of the total mortality and SCD post ST elevation myocardial infarction (MI) constitutes for about half of total deaths.ObjectiveGiven the limitations of existing therapy there is a need for an effective, easy to use, broadly applicable and affordable intervention to prevent SCD post MI. Leading cardiologists from all over India came together to discuss the potential role of n-3 acid ethyl esters (90%) of eicosapentaenoic acid (EPA) 460 mg & docosahexaenoic acid (DHA) 380 mg in the management of post MI patients and those with hypertriglyceridemia.RecommendationsHighly purified & concentrated omega-3 ethyl esters (90%) of EPA (460 mg) & DHA (380 mg) has clinically proven benefits in improving post MI outcomes (significant 15% risk reduction for all-cause mortality, 20% risk reduction for CVD and 45% risk reduction in SCD in GISSI-Prevenzione trial) and in reducing hypertriglyceridemia, and hence, represent an interesting option adding to the treatment armamentarium in the secondary prevention after MI based on its anti-arrhythmogenic effects and also in reducing hypertriglyceridemia. 相似文献

The Pneumonia Severity Index (PSI) is a validated risk assessment tool for patients with community-acquired pneumonia (CAP). Guidelines endorse outpatient treatment for patients deemed low risk, but experience shows that such patients are frequently hospitalized. We investigated the limitations of the PSI as a triage tool by examining outcomes in patients whose disposition from the Emergency Department differed from that predicted by the PSI. PSI scores were calculated by retrospective chart review for all adults with CAP presenting to the Emergency Department of a university medical center. Disposition was classified as consistent with the PSI when low-risk patients were discharged and high-risk patients were admitted. Charts of low-risk patients whose disposition was inconsistent with the PSI were abstracted for documentation of comorbidities contributing to the admission decision, as well as length of stay and level of care. There were 174 patients with CAP who met inclusion criteria, and 32% had a disposition inconsistent with the PSI. Eighty-six percent of the inconsistencies involved low-risk patients admitted to the hospital, and 41% of all low-risk patients with CAP were hospitalized. Hypoxia contributed to the decision to admit in 48% of these patients. Average length of stay was 5.2 days, and 78% of patients remained in the hospital > 48 h. Hypoxia was the most frequent factor contributing to admission of low-risk patients with CAP. Low-risk inpatients had a significant length of stay, suggesting that clinical judgment appropriately superseded the PSI in these cases. 相似文献

Eighty patients with primary carcinoma of the gallbladder were studied by ultrasonography. Two broad groups were defined. In group I (72.5%), the gallbladder lumen was identified along with a mass lesion, and in group II (27.5%), a large mass totally replacing the gallbladder was seen. Group I was further categorized into three subtypes according to the morphology of the lesion: type 1--a mass almost filling the lumen; type 2--a polypoidal mass projecting into the lumen; and type 3--an infiltrating mass. Associated findings of infiltration of the liver, presence of calculi, biliary tree obstruction, liver metastasis, and lymphadenopathy further supported the diagnosis. Ultrasonography was found to be highly reliable in the diagnosis of carcinoma of the gallbladder. In addition, it provided guidance for biopsy/aspiration of nonpalpable tumors. Its shortcomings appear to be its inability to assess peritoneal and bowel involvement, as well as that of the omentum and posterior rectus sheath. 相似文献

Assays of serum lipase: analytical and clinical considerations 总被引:1,自引:0,他引:1
We evaluated three commercially available methods for determining lipase (EC 3.1.1.3) in serum--the Du Pont aca, Boehringer Mannheim Diagnostics (BMD), and Kodak Ektachem (EK) procedures--for their analytical properties and diagnostic efficiencies. Titrimetry was used as the comparative method. The BMD and EK methods showed better agreement with the titrimetric method, owing to the presence of the necessary cofactor, colipase, in their reagents. Colipase also increased the analytical sensitivity of the BMD and EK procedures as compared with the aca method. Determinations of serum lipase, by all methods, had a clinical sensitivity in excess of 80% for acute pancreatitis; the specificity of the lipase test was about 60%, or twice that of serum amylase. Serum lipase determinations with the current, simpler technology are superior to total amylase in the diagnosis of patients with acute pancreatitis. When a colipase-supplemented method is used, a serum lipase value greater than 10-fold the upper reference limit appears to be pathognomonic for acute pancreatitis or inflammation of organs close to the pancreas. 相似文献

Recurrence of hepatitis C (HCV) postliver transplant is universal, with a subgroup developing rapid hepatic fibrosis. Toll‐like receptors (TLRs) are critical to innate antiviral responses and HCV alters TLR function to evade immune clearance. Whether TLRs play a role in rapid HCV recurrence posttransplant is unknown. We stimulated peripheral blood mononuclear cells (PBMCs) from 70 patients with HCV postliver transplant with TLR subclass‐specific ligands and measured cytokine production, TLR expression and NK cell function. Rate of fibrosis progression was calculated using posttransplant liver biopsies graded by Metavir scoring (F0–4; R = fibrosis stage/year posttransplant; rapid fibrosis defined as >0.4 units/year). Thirty of 70 (43%) patients had rapid fibrosis progression. PBMCs from HCV rapid‐fibrosers produced less IFNα with TLR7/8 stimulation (p = 0.039), less IL‐6 at baseline (p = 0.027) and with TLR3 stimulation (p = 0.008) and had lower TLR3‐mediated monocyte IL‐6 production (p = 0.028) compared with HCV slow fibrosers. TLR7/8‐mediated NKCD56 dim cell secretion of IFNγ was impaired in HCV rapid fibrosis (p = 0.006) independently of IFNα secretion and TLR7/8 expression, while cytotoxicity remained preserved. Impaired TLR3 and TLR7/8‐mediated cytokine responses may contribute to aggressive HCV recurrence postliver transplantation through impaired immune control of HCV and subsequent activation of fibrogenesis. 相似文献
