IntroductionThe best techniques for reduction of femoral access site complications after transcatheter aortic valve implantation (TAVI) remain the object of research.AimWe report on a single center’s experience with TAVI performed via the femoral access site.Material and methodsBetween September 2010 and September 2015, 152 consecutive patients underwent TAVI in our department. Of them, 101 patients with CoreValve implantation from the femoral access site were included in the analysis. The femoral artery anatomy-tailored approach was introduced in 2013 in order to reduce the rate of access-site complications. Patients were assigned to percutaneous puncture or surgical cut-down depending on the femoral artery anatomy assessed in computed tomography. The study patients were divided into two subgroups: group A – patients treated before January 2013, before introduction of the tailored approach program (n = 34); and group B – patients treated between January 2013 and April 2015 (n = 67).ResultsThe access site complication rate significantly decreased from 35.3% in group A (n = 12) to 7.5% in group B (n = 5) (p = 0.0012). Both minor and major access site complications were more frequent in group A (p = 0.04 and 0.016, respectively). In-hospital mortality was 8.8% (n = 3) in group A and 1.5% (n = 1) in group B (p = 0.1).ConclusionsThe femoral artery anatomy-tailored approach significantly reduces the incidence of access site complications in TAVI patients.
Neuropsychiatria i Neuropsychologia 2016 135Artykuł poglądowy/Review article S t r e s z c z e n i e Stenoza aortalna w krajach rozwiniętych jest najczęst-szą nabytą wadą zastawkową serca. Złotym standardem leczenia pozostaje chirurgiczna wymiana zastawki aortalnej, ale u części pacjentów z powodu wysokiego ryzyka okołooperacyjnego wybierana jest metoda przezcewnikowego wszczepienia protezy zastawki aortalnej (transcatheter aortic valve implantation -TAVI). Powikłaniem pogarszającym wyniki TAVI mogą być incydenty zatorowe w obrębie ośrodkowego ukła-du nerwowego (OUN). Badania z zastosowaniem obrazowania ruchów cząsteczek wody w przestrzeni zewnątrz komórkowej sugerują, że TAVI, podobnie jak inne interwencje kardiologiczno-kardiochirurgiczne, jest obarczone zwiększonym ryzykiem występowania mikrozatorów. Upośledzenie przepływu naczyniowego w obrębie tkanki mózgowej może spowodować uszkodzenie struktur mózgu i w konsekwencji zaburzenia jego funkcjonowania. Może prowadzić do utrudnień w pooperacyjnym funkcjonowaniu pacjentów i w readaptacji środowiskowej, a jednocześnie być przyczyną dodatkowego stresu u tych chorych. Świadomość tych zagrożeń u pacjentów wymagających implantacji protezy zastawki aortalnej skłania personel wykonujący tego rodzaju zabiegi do monitorowania nasilenia upośledzenia funkcjonowania mózgu, a postęp technologiczny w zakresie metod i systemów tej endowaskularnej procedury ma na celu zmniejszenie liczby powikłań, w tym ochronę OUN. Ważnym, ale słabo poznanym zagadnieniem jest ocena funkcji poznawczych w okresie okołozabiegowym i pozabiegowym u pacjentów poddawanych procedurze TAVI. W niniejszym opracowaniu zwrócono uwagę na dwa aspekty -pogorszenie funkcji poznawczych z powodu okołozabiegowego upośledzenia ukrwienia OUN oraz ich potencjalną poprawę wynikającą z poprawy hemodynamicznej po zabiegu. Wpływ TAVI na zaburzenia funkcji poznawczych jest wciąż niejasny i wymaga dalszych badań.Słowa kluczowe: TAVI, funkcje poznawcze, testy neuropsychologiczne, neuroobrazowanie.
The rapid development of new technologies has caused interest in the use of socially assistive robots in the care of older people. These devices can be used not only to monitor states of health and assist in everyday activities but also to counteract the deterioration of cognitive functioning. The aim of the study was to investigate the attitudes and preferences of Polish respondents towards interventions aimed at the preservation/improvement of cognitive functions delivered by a socially assistive robot. A total of 166 individuals entered the study. Respondents completed the User’s Needs, Requirements and Attitudes Questionnaire; items connected to cognitive and physical activity and social interventions were analyzed. Perceptions and attitudes were compared by gender and age groups (older adults ≥ 60 years old and younger adults 20–59). Women showed a more positive attitude towards robots than men and had a significantly higher perception of the role of the robots in reminding about medications (p = 0.033) as well as meal times and drinks (p = 0.018). There were no significant differences between age groups. Respondents highly valued both the traditional role of the robot—a reminding function—as well as the cognitive interventions and guided physical exercises provided by it. Our findings point to the acceptance of the use of socially assistive robots in the prevention of cognitive deterioration in older people.
Objectives. Second generation antidepressants belong to the most commonly prescribed medications; they are used in the treatment of depression, anxiety disorder, and pain. The aim of the study is to evaluate their risk of QT prolongation, which can lead to potentially life-threatening ventricular arrhythmias. Literature review. Based on the Summary of Product Characteristics and CredibleMeds database, we present current knowledge about the risk of QT prolongation caused by second generation antidepressants. Recommendations concerning planning and conducting treatment using second generation antidepressants are discussed. Conclusions. As scientific research shows, newer antidepressants cause fewer side effects than tricyclic antidepressants, but they are not devoid of them. For some of them, there is a proven risk of QT prolongation and torsade de pointes, which can, very rarely, lead to patient’s death. Before prescribing new antidepressants, clinicians should evaluate the patient’s risk of QT prolongation and, in case of high risk, they should apply the lowest effective dose, regularly monitor the patient’s condition, and inform the patient to consult a cardiologist if any alarming symptoms, such as syncope or palpitations, occur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
