Co-detection of respiratory pathogens in patients hospitalized with Coronavirus viral disease-2019 pneumonia.

2020

ABSTRACTThere is scarce information on the frequency of co-detection of respiratory pathogens (RP) in patients with Covid-19. Documentation of coinfections in Covid-19 pneumonia patients may be relevant for appropriate clinical and therapeutic management of patients. Between March 4th and March 28th, 2020, a total of 183 adult patients testing positive by SARS CoV-2 RT-PCR on respiratory specimens were hospitalized with interstitial pneumonia at our center, of whom 103 were tested for other RP by a multiplexed PCR assay. Three patients had a positive result for either one (n=2; Coronavirus HKU1 or Mycoplasma pneumoniae) or two targets (n=1; Influenza virus A (H3) and Respiratory syncytial v…

Persistence of High Plasma Elastase Level in Young Subjects With Acute Myocardial Infarction

Changes in plasma lipids and low-density lipoprotein peak particle size during and after acute myocardial infarction

2002

In summary, LDL peak particle size variations occur very early after AMI, and therefore this parameter, which may be considered a genetically determined risk factor, must be measured not before 2 to 3 months after the acute event.

Bone Marrow Findings in Multicentric Castleman Disease in HIV-negative Patients

2007

Because bone marrow histology in multicentric Castleman disease in human immunodeficiency virus-negative patients is not well reported, we investigated sequential bone marrow biopsies of 3 affected human immunodeficiency virus-negative patients, of which one was human herpes virus 8 (HHV8)-positive. The histologic evaluation of the bone marrow revealed lymphoid follicles with regressed germinal centers in 1 patient. Another patient showed tumorlike but bland polyclonal plasmacytosis with large perivascular plasma cell clusters. The HHV8-positive patient revealed interstitial HHV8-positive cells accompanied by a mild plasmacytosis. The atypical lymphoid follicles could be regarded as a bone …

Heredity and obesity-associated hypertension: impact of hormonal characteristics and left ventricular mass.

1995

Objectives : To investigate the influence of heredity on obesity-associated hypertension, we evaluated casual and 24-h blood pressure, left ventricular mass and some metabolic and hormonal measurements in normotensive obese subjects. Design : Healthy, normotensive obese subjects (n = 81) with positive or negative family history of hypertension were studied. Both groups were also subdivided according to a positive or a negative family history of obesity. Accordingly, 45 obese subjects had a positive family history of hypertension, 25 of these having a positive (subgroup A) and 20 having a negative family history of obesity (subgroup B). The other 36 obese subjects had a negative family histo…

Effects of marathon running on running economy and kinematics.

2000

The present study was designed to investigate interactions between running economy and mechanics before, during, and after an individually run marathon. Seven experienced triathletes performed a 5-min submaximal running test on a treadmill at an individual constant marathon speed. Heart rate was monitored and the expired respiratory gas was analyzed. Blood samples were drawn to analyze serum creatine kinase activity (S-CK), skeletal troponin I (sTnI), and blood lactate (B-La). A video analysis was performed (200 frames · s−1) to investigate running mechanics. A kinematic arm was used to determine the external work of each subject. The results of the present study demonstrate that after the …

Zinc and smoking habits in the setting of hypertension in a Spanish populations.

2014

The objective of this study was to evaluate the relationship between trace and toxic amounts of zinc (Zn) in biological samples (blood and urine) and the smoking habits of hypertensive patients and healthy control subjects in Valladolid (Spain). In order to compare biological samples, the concentrations of these samples were measured using inductively coupled plasma mass spectrometry. The limits of detection for Zn in blood plasma ranged between 4.22 and 17.34 μmol l(-1) and were <0.08 μmol g(-1) creatinine in urine. The results of this study indicate that the highest mean values of serum Zn were found in non-hypertensive nonsmokers (13.39±4.35 μmol l(-1)), whereas the highest urine Zn valu…

Influence of plasma cleaning procedure on the interaction between soft tissue and abutments: a randomized controlled histologic study

2016

Introduction Plasma application can lead to an improved adhesion between soft tissue and abutments and promotes cell spreading. Objective A triple-blinded randomized controlled clinical trial was performed to in vivo test the effect of cleaning abutment titanium surfaces with plasma of argon on cell adhesion and collagen fiber orientation at an early healing time. Material and methods Thirty healthy patients with 30 submerged implants, at the second surgery, randomly received either a specially designed abutment with no additional treatment (as they come from industry; control group, G1) or cleaned by plasma of argon (test group, G2). Two weeks thereafter, a small biopsy including abutment …

Plasma noradrenaline and the pressor action of exogenous noradrenaline in normotensive subjects and patients with essential hypertension.

1978

1. An inverse relationship was found between plasma noradrenaline and reactivity to exogenous noradrenaline in normotensive subjects. 2. The relationship between plasma noradrenaline and reactivity was disturbed in age-matched patients with essential hypertension. 3. A multiple-regression analysis showed a highly significant correlation between adrenergic activity and reactivity to noradrenaline and the mean arterial blood pressure level (r = 0·91). The results suggest that adrenergic activity and pressor response to noradrenaline combined are important determinants of arterial blood pressure. 4. An inverse relationship could also be demonstrated between plasma renin activity and reactivity…

Effect of Lanadelumab Compared With Placebo on Prevention of Hereditary Angioedema Attacks: A Randomized Clinical Trial.

2018

Current treatments for long-term prophylaxis in hereditary angioedema have limitations.To assess the efficacy of lanadelumab, a fully human monoclonal antibody that selectively inhibits active plasma kallikrein, in preventing hereditary angioedema attacks.Phase 3, randomized, double-blind, parallel-group, placebo-controlled trial conducted at 41 sites in Canada, Europe, Jordan, and the United States. Patients were randomized between March 3, 2016, and September 9, 2016; last day of follow-up was April 13, 2017. Randomization was 2:1 lanadelumab to placebo; patients assigned to lanadelumab were further randomized 1:1:1 to 1 of the 3 dose regimens. Patients 12 years or older with hereditary a…
