Background: Sustained hypotension, cardiogenic shock, and heart failure all imply a poor prognosis in acute myocardial infarction (MI). We assessed the benefit of adding 48 hours of intra-aortic balloon counterpulsation (IABP) to standard treatment for MI, in an international trial among hospitals without primary angioplasty capabilities.Methods: We randomized 57 patients with MI complicated by sustained hypotension, possible cardiogenic shock, or possible heart failure to receive either fibrinolytic therapy and IABP or fibrinolysis alone. The primary end point was all-cause mortality at 6 months.Results: In all, IABP was inserted in 27 of 30 assigned patients a median 30 minutes after fibrinolysis began and continued for a median 34 hours. Of the 27 patients assigned to fibrinolysis alone, 9 deteriorated such that IABP was required. The IABP group was at slightly higher risk at baseline, but the incidence of the primary end point did not differ significantly between groups (34% for combined treatment versus 43% for fibrinolysis alone; adjusted P = 0.23). Patients with Killip class III or IV showed a trend toward greater benefit from IABP (6-month mortality 39% for combined therapy versus 80% for fibrinolysis alone; P = 0.05).Conclusions: While early IABP use was not associated with a definitive survival benefit when added to fibrinolysis for patients with MI and hemodynamic compromise in this small trial, its use suggested a possible benefit for patients with the most severe heart failure or hypotension.Abbreviated Abstract. We assessed the benefit of adding 48 hours of intra-aortic balloon counterpulsation to fibrinolytic therapy among 57 patients with acute myocardial infarction complicated by sustained hypotension, possible cardiogenic shock, or possible heart failure. The primary end point, mortality at 6 months, did not differ between groups (34% for combined treatment versus 43% for fibrinolysis alone [n = 27]; adjusted P = 0.23), although patients with Killip class III or IV did show a trend toward greater benefit from IABP (39% for combined therapy versus 80% for fibrinolysis; P = 0.05). 相似文献

An elevated human T cell lymphotropic virus 1 (HTLV)-1 proviral load (PVL) is the main risk factor for developing HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in HTLV-1 infected subjects, and a high cerebrospinal fluid (CSF) to peripheral blood mononuclear cell (PBMC) PVL ratio may be diagnostic of the condition. However, the standard method for quantification of HTLV-1 PVL—real-time PCR—has multiple limitations, including increased inter-assay variability in compartments with low cell numbers, such as CSF. Therefore, in this study, we evaluated a novel technique for HTVL-1 PVL quantification, digital droplet PCR (ddPCR). In ddPCR, PCR samples are partitioned into thousands of nanoliter-sized droplets, amplified on a thermocycler, and queried for fluorescent signal. Due to the high number of independent events (droplets), Poisson algorithms are used to determine absolute copy numbers independently of a standard curve, which enables highly precise quantitation. This assay has low intra-assay variability allowing for reliable PVL measurement in PBMC and CSF compartments of both asymptomatic carriers (AC) and HAM/TSP patients. It is also useful for HTLV-1-related clinical applications, such as longitudinal monitoring of PVL and identification of viral mutations within the region targeted by the primers and probe. 相似文献

Anti-T-cell lymphocyte globulin (ATLG) and posttransplant cyclophosphamide (PTCy) are now widely used strategies to prevent graft-versus-host disease (GVHD) after allogeneic stem cell transplantation. Data comparing immune reconstitution (IR) between ATLG and PTCy is scarce. This retrospective study conducted at the University Medical Center Hamburg-Eppendorf (UKE) compares PTCy (n=123) and ATLG (n=476) after myeloablative allogeneic peripheral blood stem cell transplant. Detailed phenotypes of T, B natural killer (NK), natural killer T (NKT) cells were analyzed by multicolor flow at day 30, 100 and 180 posttransplant. Incidence of infections, viral reactivations, GVHD and relapse were collected. Neutrophil engraftment was significantly delayed in the PTCy group (median day 12 vs. day 10, P<0.001) with a high incidence of infection before day+100 in the PTCy arm but a higher Epstein-Barr virus reactivation in the ATLG arm and comparable cytomegalovirus reactivation. Overall incidence of acute GVHD was similar but moderate/severe chronic GVHD was seen more often after PTCy (44% vs. 38%, P=0.005). ATLG resulted in a faster reconstitution of CD8+ T, NK, NKT and gdT cells while CD4 T cells and B cells reconstituted faster after PTCy. Similar reconstitution was observed for T-regulatory cells and B cells. Non-relapse mortality relapse incidence, disease-free survival, and overall survival did not differ significantly between both arms. Even though differences in IR were related to a decreased incidence of infection and moderate/severe cGVHD in the ATLG group they had no impact on any of the other long-term outcomes. However, it remains undetermined which regimen is better as GVHD prophylaxis. 相似文献

Ethnopharmacological relevance
The experimental finding of Asian traditional medicine revealed the pharmacological effect of the local application of ghee which was taken from cow butterfat and the rhizomes of Curcuma longa. These materials significantly improved the healing process of the wound. In addition, ancient physicians of Middle East discovered that the powdered rhizomes of Curcuma longa (common turmeric) also had impressive medicinal qualities. Over the centuries, this spice has been used as a pain relieving, anti-inflammatory agent to relieve pain and inflammation in the skin and muscles.Aim of the study
We decided to mix ghee which was taken from sheep butterfat with the powdered rhizomes of Curcuma longa to formulate a novel cost-benefit material and then, evaluate its potential therapeutic effect on acceleration of surgical wound healing; moreover, this present study was performed to compare the effects of Curcuma longa–ghee formulation and hyaluronic acid on gingival wound healing following surgery.Materials and methods
Five healthy 3-year-old male beagle dogs were used in this study. They had intact teeth and the clinical and radiographic examination revealed no periodontal disease. Ghee was obtained from the refined sheep butterfat heated to 70 °C mixed with the powdered rhizomes of Curcuma longa and was applied with two different ratios including materials A and B. Randomly, these three materials including hyaluronic acid, materials A and B were applied topically in test regions and then covered with periodontal pack. Histological changes were monitored in days 4 and 7 after operation to evaluate the inflammatory and repair stage of healing process.Results
We observed significant difference in the inflammatory and repair parameters of the healing process between cases treated with this new formulation and cases of hyaluronic acid application.Conclusion
The results suggested a positive potential therapeutic effect on surgical wound healing particularly improvement of periodontal treatment consequences after surgery. 相似文献36.
INTRODUCTION: Leiomyosarcoma of the large bowel mesentery is a rare entity and characteristically behaves in an aggressive fashion. Surgical resection is the mainstay of treatment and offers both symptomatic and therapeutic benefit. CASE: We describe the case of a 55-year-old woman who presented with weight loss, increasing abdominal girth and a large solid inhomogenous mass within the abdomen and pelvis demonstrated on a computed tomography (CT) scan. The patient underwent an exploratory laparotomy and extensive tumor debulking procedure with complete resection of her tumor. Final pathology revealed leiomyosarcoma of the large bowel mesentery. The patient has chosen not to receive adjuvant therapy. CONCLUSIONS: Leiomyosarcoma of the large bowel mesentery often presents as an advanced lesion making surgical resection a challenging and potentially morbid procedure. Although surgical resection may be faced with significant morbidity, maximum surgical effort with complete resection offers the best overall outcome for patients with this disease. 相似文献

AIMS: We evaluated serum angiotensin-converting enzyme (ACE) as an indicator of gentamicin toxicity and compared it with N-acetyl-beta-D-glucosaminidase (NAG) and creatinine. METHODS: 20 bone fracture in-patients receiving gentamicin 80 mg TDS for 3 days. Subjects had normal kidney function and had no history or sign of hypertension. Serum and urine samples were collected before and 3 days after drug administration. Samples analyzed for ACE, NAG, BUN, creatinine, sodium, and potassium. RESULTS: Our results showed that urine NAG activity increased significantly at the 3rd day. Serum creatinine level and glomerular filtration rate (GFR) while still at a normal range showed slight but significant changes at this time. This may indicate some renal damage. Serum ACE activity decreased significantly at the 3rd day. CONCLUSION: These results indicate serum ACE can be used as a good indicator of renal damage in patients receiving gentamicin. 相似文献

In order to suggest therapy modifications with the aim of diminishing the risk of therapy-induced long-term distressful symptoms in cancer survivors, data are needed relating details of therapy to the long-term symptom situation. In this article, the concepts and means used to assess the latter while developing the Radiumhemmet scale for symptom assessment are described. The focus is on the subjective long-term situation, and symptoms as a perceived abnormality are defined. For conceptual clarity, one symptom at a time is considered, excluding scales in which items are summarized. Moreover, measures of disease occurrence in the population are translated (epidemiologically) into measures of symptom occurrence in an individual. Nature distinguishes one long-term symptom from another. Occurrence of a symptom in an individual is measured by an incidence (e.g. number of defecations per week) or prevalence rate (e.g. urinations with involuntary cessation divided by the total number of urinations). Any scale expressing symptom intensity is arbitrary, be it 'verbal' (no/little/moderate/much pain) or visual (analogue or with integers). A time period describes symptom duration. The relevance of a symptom to emotions and social activities, sometimes cited as the associated symptom-induced distress, is a separate issue from symptom occurrence, intensity, and duration. 相似文献
