TAVI after More Than 20 Years
Get PDF: It has been more than 20 years since the first in man transcatheter aortic valve intervention (TAVI), and during this period we have witnessed an impressive evolution of this technique, with an extension of its use from non-operable patients to high-, intermediate- and even low-risk patients with aortic stenosis, and with a decrease in the incidence of complications. In this review, we discuss the evaluation of patients before TAVI, the procedure and the changes it has seen over time, and we present the current main complications and challenges of TAVI
Exercise echocardiography in aortic stenosis with preserved ejection fraction
No full textThe appropriate timing of intervention and follow-up in asymptomatic patients with aortic stenosis remains controversial. Risk stratification is a key, especially with the use of a multimodality imaging approach, including exercise stress echocardiography. This review focuses on the use of exercise echocardiography in asymptomatic patients with moderate and severe aortic stenosis with preserved left ventricular ejection fraction. It describes the exercise echocardiography protocol, parameters to be evaluated, and its role in guiding the timing of intervention and follow-up in these patients

Post-Thyroidectomy Hypocalcemia: Timing of Discharge Based on Serum Calcium Levels
Get PDFPurpose: The study concerns about the evaluation of Calcium serum levels in patients who underwent
total thyroidectomy. Our previous experience underlined how patients who had levels
of serum Calcium more than 9 mg/dl at the first day after surgery, did not show Hypocalcemia
in the next days,so that this value could be considered a good cut-off for the decision of an
early discharge. With regards to this experience, the aim of our current study was to confirm
the effective feasibility of an early discharge based on the levels of serum Calcium at the first
post-operative day.
Patients and Methods: Our study included 102 consecutive patients (82 F; 20 M, age with a
range between 14-78 year sold, average 52.6) that were submitted to total thyroidectomy in the
years 2010 to 2014, performed by the same operator and all done with sutureless technique (Ligasure
precise©) We classify hypocalcemia, according to their normal range (8.6 to 10.4 mg/dl),
in mild (not less than 7.6 mg/dL), moderate (between 7.5 mg/dL and 7 mg/dL) and severe (less
than 7 mg/dL) We classified the normal range of serum Calcium between 8.6 mg/dl and 10.4
mg/dl. Patients that showed levels of serum Calcium under this limit (<8.6 mg/dl) were treated
with 6 fials of Gluconate Calcium 40 mEq in 500 ml of saline solution NaCl 0.9% i.v. (one per
day), until the return to the normal range. Patients who had serum Calcium levels more than 9
mg/dl at the first post-operative days, and did not have other complications, were discharged at
the same day and revaluated after 7 days.
Discussion and Conclusion: Moreover our study has been useful to confirm what we observed
in the previous experience, that levels of serum Calcium more than 9 mg/dl at the first postoperative
day can be considered a feasible cut-off to exclude the appearance of hypocalcaemia
in future.
Therefore, according to our results, we assume to propose an early discharge for the patients
who have serum Calcium levels more than 9 mg/dl, asking them to come back for controls one
week after discharge
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
