Early vs Late Anticoagulation After Ischemic Stroke in Patients With Atrial Fibrillation and Covert Brain Infarcts.

Background And Objectives: Covert brain infarcts (CBIs) in patients with first-ever ischemic stroke (IS) and atrial fibrillation (AF) are associated with an increased risk of stroke recurrence. We aimed to assess whether CBIs modify the treatment effect of early vs late initiation of direct oral anticoagulants (DOACs) in patients with IS and AF.

Methods: We conducted a post hoc analysis of the international, multicenter, randomized-controlled ELAN trial, which compared early (<48 hours after ischemic stroke for minor and moderate stroke, 6-7 days for major stroke) vs late (>48 hours for minor, 3-4 days for moderate, 12-14 days for major stroke) initiation of DOACs in patients with IS and AF.

Early versus Later Anticoagulation for Stroke with Atrial Fibrillation.

Background: The effect of early as compared with later initiation of direct oral anticoagulants (DOACs) in persons with atrial fibrillation who have had an acute ischemic stroke is unclear.

Methods: We performed an investigator-initiated, open-label trial at 103 sites in 15 countries. Participants were randomly assigned in a 1:1 ratio to early anticoagulation (within 48 hours after a minor or moderate stroke or on day 6 or 7 after a major stroke) or later anticoagulation (day 3 or 4 after a minor stroke, day 6 or 7 after a moderate stroke, or day 12, 13, or 14 after a major stroke).

Zygomycosis in Italy: a survey of FIMUA-ECMM (Federazione Italiana di Micopatologia Umana ed Animale and European Confederation of Medical Mycology).

The aims of the study were to analyze the clinical and epidemiological characteristics and treatments for patients who developed zygomycosis enrolled in Italy during the European Confederation of Medical Mycology of medical mycology survey. This prospective multicenter study was performed between 2004 and 2007 at 49 italian Departments. 60 cases of zygomycosis were enrolled: the median age was 59.

[Protein C and coagulation in sepsis].

The last few years have clarified the tight link between inflammation and coagulation. In addition to the identification of new regulatory mechanisms of the coagulation system and of an explosive number of mediators of inflammation, it is now clear that the existence of a positive feed-back between inflammation and coagulation leads to reciprocal activation of both pathways. Plasma levels of acute phase proteins involved in coagulation and fibrinolysis are elevated during inflammation, while natural anticoagulant mechanisms are depressed.

[Infection surveillance in intensive care units. Preliminary results of a multicenter GiViTI study in 71 Italian ICUs].

Aim: Infection surveillance and control in ICU is believed to be a means to improve the quality of assistance. The importance of this activity is supported by both epidemiological (rate and severity of infection in ICU) and economic (efficiency, cost-benefit and cost-effectiveness analysis) evaluations. Many authors thinks that infection surveillance and control should be performed with a routine tool in order to obtain remarkable data without too much time loss, and used by many ICUs, in order to compare the data.

Cardiovascular outcomes after kidney-pancreas and kidney-alone transplantation.

Background: This study retrospectively assessed, with an intention-to-treat analysis, the effect of kidney-pancreas transplantation (KP) on survival and cardiovascular outcome in type 1 diabetic uremic patients.

Methods: A total of 351 uremic type 1 diabetic patients were enrolled on a waiting list for KP: 130 underwent KP transplantation, 25 underwent kidney transplantation alone (KA), whereas 196 patients remained on dialysis (WL). The three populations had similar cardiovascular conditions.

Patient survival and cardiovascular events after kidney-pancreas transplantation: comparison with kidney transplantation alone in uremic IDDM patients.

In diabetic patients cardiovascular morbidity and mortality is still a major problem. Our aim was to study the effect of kidney-pancreas transplantation on survival, cardiovascular events, and causes of death in diabetic type 1 uremic patients. Three hundred and thirty-three uremic IDDM patients were enrolled in our waiting list for kidney-pancreas transplantation: 107 underwent kidney-pancreas transplantation (KP), 34 underwent kidney transplantation alone (KA), whereas 192 patients remained on dialysis (WL).

Reversal of left ventricular diastolic dysfunction after kidney-pancreas transplantation in type 1 diabetic uremic patients.

Objective: Diastolic function is frequently impaired in diabetic patients. Our aim was to evaluate the effects of glycometabolic control achieved by pancreas transplantation on left ventricular function in uremic type 1 diabetic patients.

Research Design And Methods: Left ventricular systolic and diastolic functions were evaluated using radionuclide ventriculography in 42 kidney-pancreas transplant patients and 26 kidney-alone recipients who had similar clinical characteristics before transplantation.

[Retinoic acid syndrome. Severe respiratory insufficiency treated with CPAP].

Retinoic acid syndrome is a potentially life-threatening complication of therapy for acute promyelocytic leukemia (APL) with all-transretinoic acid (ATRA). The case of a 55-year old male patient admitted to the hospital because of a bleeding diathesis is reported. APL was diagnosed and he underwent treatment with idarubicin and ATRA (GIMEMA protocol); 24 hrs after ATRA treatment he developed retinoic acid syndrome and was admitted to the Intensive Care Unit because of severe respiratory insufficiency (dyspnoea, tachypnea and severe hypoxemia (SpO2 75%).

Antithrombin replacement in patients with sepsis and septic shock.

Sepsis is a frequent complication of critically ill patients and its incidence is increasing. Currently, septic shock is the most common cause of death in non-coronary intensive care units. Over the last 10 to 15 years, new antibiotics and increasingly sophisticated critical care have had little impact on the mortality rate of septic shock.

Mono-oligoclonal immunoglobulin abnormalities in diabetic patients after kidney transplantation: influence of simultaneous pancreas graft.

Monoclonal components (MC) are detected in as high as 30% of renal transplant recipients. Our aim was to evaluate the incidence, relevance and consequence of monoclonal components in patients with Type I (insulin-dependent) diabetes who received kidney (n = 22), kidney and whole pancreas (n = 41), kidney and segmental pancreas (n = 24) and kidney and islets (n = 12) transplants. Immuno-suppression was based on prophylactic anti-lymphocyte globulins, corticosteroids, azathioprine and cyclosporin in all patients; acute rejection was treated with steroids or anti-lymphocyte monoclonal immunoglobulin therapy (OKT3) or both.

Effect of the 5 alpha-reductase inhibitor PNU 156765, alone or in combination with flutamide, in the Dunning R3327 prostatic carcinoma model in rats.

The efficacy of treatment with the 5 alpha-reductase inhibitor PNU 156765 (FCE 28260) was investigated in the Dunning R3327 prostatic tumor in rats. The compound, given orally at the doses of 10 and 50 mg/kg/day, for 8 weeks, reduced the growth of established tumors by 49-50%, an effect similar to that of flutamide at 5 mg/kg/day (46% inhibition). In a further experiment, the combination of PNU 156765 10 mg/kg/day and flutamide 5 mg/kg/day resulted in greater inhibition than either treatment alone (70 vs.

Effect of early treatment of prostate cancer with the 5alpha-reductase inhibitor turosteride in Dunning R3327 prostatic carcinoma in rats.

Background: Turosteride, a selective 5alpha-reductase inhibitor, was reported to be effective in inhibiting the growth of established tumors in the Dunning R3327 rat prostatic carcinoma model. We evaluated the preventive effect of turosteride when administered during the latency period in this prostatic tumor model.

Methods: Turosteride was given orally, 6 days a week for 10-15 weeks, starting at different times: 1) 5 weeks after tumor implantation, when tumors were not yet palpable, or 2) 1 day after tumor implantation.

Antithrombin III (ATIII) replacement therapy in patients with sepsis and/or postsurgical complications: a controlled double-blind, randomized, multicenter study.

Background: ATIII is decreased in sepsis and/or shock and its baseline value correlates with mortality. The efficacy of ATIII therapy on mortality was assessed in a selected group of patients admitted to the intensive care unit (ICU) in a double-blind, randomized, multicenter study.

Methods: 120 patients admitted to the ICU with an ATIII concentration < 70% were randomized to receive ATIII (total dose 24000 units) or placebo treatment for 5 days; 56 patients had septic shock.

Effect of the dual 5alpha-reductase inhibitor PNU 157706 on the growth of dunning R3327 prostatic carcinoma in the rat.

PNU 157706 [N-(1,1,1,3,3,3-hexafluorophenylpropyl)-3-oxo-4-aza-5alpha-androst-1-ene-17beta-carboxamide] is a novel, potent and selective dual 5alpha-reductase inhibitor. We have investigated its effect on tumor growth, endocrine organ weights and prostatic dihydrotestosterone (DHT) content in rats bearing the androgen dependent Dunning R3327 prostatic carcinoma. Animals with tumor diameters of about 1 cm were treated orally for 9 weeks with PNU 157706 (2 and 10 mg/kg/day, 6 days a week) or they were castrated, to check the hormone responsiveness of the tumor.

PNU 157706, a novel dual type I and II 5alpha-reductase inhibitor.

PNU 157706 is a novel dual inhibitor of 5alpha-reductase (5alpha-R), the enzyme responsible for the conversion of testosterone (T) to 5alpha-dihydrotestosterone (DHT). Tested on a crude preparation of human or rat prostatic 5alpha-R, PNU 157706 caused enzyme inhibition with IC50 values of 20 and 34 nM, respectively, compared to the values of 32 and 58 nM shown by finasteride. Furthermore, PNU 157706 was highly potent in inhibiting human recombinant 5alpha-R type I and II isozymes, showing IC50 values of 3.

Probability model of hospital death for severe trauma patients based on the Simplified Acute Physiology Score I: development and validation. Archivio Diagnostico.

Background: We evaluated whether or not the Simplified Acute Physiology Score (SAPS) I is a suitable audit system for trauma patients admitted to general intensive care units (ICUs). A probability model for SAPS I was retrospectively assessed on trauma patients admitted to general ICUs from 1990 to 1992. Because it was determined that SAPS did not fit the data well, we developed a customized probability model of SAPS I for trauma patients and validated it prospectively on an independent data set (patients admitted to general ICU in 1993-1994).
