Jugular veins in transient global amnesia: innocent bystanders.
No full textBackground and Purpose—Transient global amnesia (TGA) has been associated with an increased prevalence of internal
jugular valve insufficiency and many patients report Valsalva-associated maneuvers before TGA onset. These findings
have led to the assumption of hemodynamic alterations in intracranial veins inducing focal hippocampal ischemia. We
investigated this hypothesis in patients with TGA and control subjects.
Methods—Seventy-five patients with TGA and 75 age- and sex-matched healthy subjects were enrolled into a
cross-sectional study. Extracranial and transcranial high-resolution venous echo-color-Doppler sonography was
performed blindly in all patients and control subjects. Blood flow direction and velocities were recorded at the internal
jugular veins, basal veins of Rosenthal, and vein of Galen, both at rest and during Valsalva-associated maneuvers.
Results—Mean age of patients with TGA was 60.38.0 years (median, 60 years; range, 44–78 years); 44 (59%) were
female (female/male ratio: 1.42). Internal jugular valve insufficiency (left, right, or bilateral) was found to be more
frequent in patients with TGA than in control subjects: 53 (70.7%) versus 22 (29.3%; P0.05). Blood flow velocities
in the deep cerebral veins of patients with TGA did not differ from control subjects both at rest and during
Valsalva-associated maneuvers. Intracranial venous reflux was neither observed in patients with TGA nor in control
subjects despite unilateral or bilateral internal jugular valve insufficiency during prolonged and maximal Valsalvaassociated
maneuvers.
Conclusions—This study, although confirming the association between TGA and internal jugular valve insufficiency,
challenges the hypothesis that cerebral venous congestion plays a significant role in the pathogenesis of TGA
Educational intervention to improve the safety medication process. a review using the GRADE approach

A worldwide bibliometric analysis of published literature on medication errors
No full textObjectives: The aim of the study was to map the recent literature on medication error to monitor the state of research and explore emerging research fronts. Specifically, the co-occurrences analysis aimed to research the conceptual structure of the medication errors, whereas the coauthorship analysis aimed to research the "authorities" that influenced the academic and political discussion on medication errors. Methods: The search for relevant studies was carried out through the Scopus. To map and monitor the state of research on medication error, a preliminary analysis was conducted through the year of publication, type of article, and language. The count of citation shows the most relevant work among those included. Bibliometric analyses were conducted, such as coauthorship analysis and co-occurrences analysis. Results: The search strategy yielded 5393 articles. Of these, 1267 articles were included. Four main themes emerged from this bibliometric analysis: (a) the exploration of human factors related to health care professionals that increase the risk of medication error, (b) the investigation of behaviors and strategies that can prevent the error in the preparation and administration stage, (c) the analysis of the benefits related to the presence of the pharmacist in hospital settings, and (d) the exploration of the consequences of a medication error and/or adverse effects of drugs. Conclusions: For the first time, a bibliometric analysis of medication errors research in the world has been conducted and demonstrated that there is a wealth of contributions already being made that are well aligned to the World Health Organization challenge
Endothelial dysfunction in carotid elongation
No full textA b s t r a c t
BACKGROUND AND PURPOSE
Internal carotid artery (ICA) elongation (coiling and kinking) has been suggested as a risk factor for carotid dissection. Since vasomotion is known to be impaired in spontaneous
cervical vessel dissection, we investigated whether endothelial-dependent vasodilation in subjects with carotid coiling and kinking is compromised.
METHODS
We undertook a case-control study using high-resolution ultrasound and measured flow mediated dilation (FMD) of the brachial artery in 80 subjects with carotid elongation and
in 80 age- and sex-matched healthy controls (HC). The hemodynamic impact of carotid elongation was taken into consideration subdividing mild/moderate kinking from severe
kinking according to a peak systolic blood flow velocity >150 cm/s.
RESULTS
FMD did not differ among subjects with coiling (14.51 ± 7.86%), mild/moderate kinking (14.38 ± 9.58%) and HC (15.53 ± 8.48%), while subjects with a severe kinking had a
significantly lower FMD (8.38 ± 3.26).
CONCLUSIONS
Among subjects with carotid elongation, those with severe kinking have an impaired endothelial-dependent vasodilation and might be prone to carotid dissection
Early Diagnosis of Type-2 Cardio-renal Syndrome by Doppler Sonographic Evaluation of Renal Vasoconstriction
No full textRenal failure of type-2 cardio-renal syndrome is due to renal hypoperfusion secondary to heart failure and is mediated by an imbalance between vasoconstrictors and vasodilators. The decrease in glomerular filtration rate does not correlate with left ventricular ejection fraction. Aim of this study was to evaluate, by Doppler sonography, renal hemodynamic alterations in heart failure. Thirty patients (age: 51±15yr) with dilated cardiomyopathy (DCM) and 20 normal subjects (C) were studied. Cardiomyopathy was essential in 36.6%, post-ischemic in 36.6%, alcoholic in 16.7%, post-myocarditis in 10% of patients. All patients were hemodynamically stable. In each patient, echocardiography and renal Doppler sonography (interlobar arterial pulsatility index, PI-K) were performed the same day, together with BUN, creatinine, NT-proBNP measurement. Patients with DCM had normal kidneys morphology and volume. LVEF was 26±6.8%. PI-K was increased compared to C (1.74±0.71 vs 0.95±0.19, p<0.001) and also renal function was impaired (creatinine 128.5±84 vs 70±30 umol/L, p<0.01, BUN 11.6±5.8 vs 7±1.5 mmol/L, p<0.01). Prevalence of renal failure was 36.6% (NYHA 1-2: 23%, NYHA 3-4: 52.9%) while prevalence of increased PI-K was 83.3% (NYHA 1-2: 69.2%, NYHA 3-4: 94.1%). PI-K was increased already in mild heart failure (NYHA 1-2) (PI-K: 1.37±0.3 p<0,01), but more so in patients with more severe heart dysfunction (NYHA 3 e 4) (PI-K: 2,1±0,8 p<0.01) without significant correlation with LVEF or right atrial pressure. There were no differences in creatinine or BUN among patients with different severity of heart dysfunction (creatinine 105±23 vs 140±104 umol/L, urea 10.3±5.7 vs 12.3±6 mmol/L). NT-proBNP was increased in patients with DCM (6249.61±3.963 ng/L) and did not correlate with LVEF, PI-K, renal function, right atrial pressure. In conclusion, in patients with chronic heart failure renal vasoconstriction can be demonstrated by Doppler-sonography in the early stage, when renal function is still normal, and increases with the worsening of heart failure. Renal Doppler resistance indices may be used for early diagnosis of type-2 cardiorenal syndrome and for prevention of acute, diuretic-induced, renal failure.

Placebo effect in acupuncture
No full textreservedIn questo elaborato si affronta la questione della pratica di agopuntura come medicina per un gran numero di condizioni cliniche. Questa terapia è infatti dibattuta a causa dei potenziali effetti placebo da cui viene influenzata. Diversi studi scientifici hanno cercato di indagare nel corso degli anni questa tecnica, utilizzando gruppi di controllo per evidenziare gli effetti specifici dell’agopuntura. Per questa ragione, in questa tesi di laurea viene proposto un protocollo sperimentale innovativo, progettato per valutare l’efficacia dell’agopuntura come trattamento rilassante.
Nel primo capitolo viene innanzitutto descritta la pratica dell’agopuntura e le sue storiche origini. Vengono anche introdotti gli effetti analgesici e terapeutici supportati da alcune evidenze che questa terapia può procurare. Infine, vengono esposti i possibili meccanismi neurobiologici sottostanti alla generazione di questi effetti.
Il secondo capitolo approfondisce l’effetto placebo e le sue conseguenze nella pratica di agopuntura. In relazione a questo vengono quindi trattati alcuni metodi a cui si è fatto ricorso per controllare questo effetto nelle condizioni sperimentali.
In conclusione, il terzo capitolo si concentra sulla descrizione del nuovo protocollo sperimentale. Esso prevede uno studio condotto in doppio cieco e con tre gruppi di controllo per evidenziare al meglio le differenze nell’induzione del rilassamento tra le varie condizioni di trattamento. Viene perciò descritta la procedura che verrà seguita e la strumentazione che verrà utilizzata per misurare e confrontare i risultati
The literary canon on television: An analysis of Borges por Piglia on Argentinian TV Pública
No full textDistintos autores han ubicado a Jorge Luis Borges como la figura central del canon literario argentino del siglo XX, con una gravitación que se extiende hacia escritores de toda América Latina. El objetivo del presente artículo es analizar uno de los más recientes y relevantes actos de canonización de Borges: el programa Borges por Piglia de la Televisión Pública Argentina, producido en 2013. Se trata de cuatro conferencias transmitidas por televisión, con gran circulación masiva posterior en internet, a cargo del escritor Ricardo Piglia. El presente trabajo propone una indagación de los aspectos discursivos y comunicativos de las conferencias para comprender en qué consiste este gesto de producción de valor sobre la obra de Borges. Se analizará el ethos de Piglia como locutor, la centralidad de la calidad literaria en su argumentación y los esfuerzos de volver a Borges un escritor cercano a un público general. A su vez, será una estrategia analítica clave establecer comparaciones con otras intervenciones realizadas por otros críticos que también indagan la obra de Borges. El trabajo se propone así pensar nuevas reconfiguraciones del canon literario argentino, enmarcadas en una política cultural pública.Several authors have placed Jorge Luis Borges as the most relevant author in Argentinian 20th century literary cannon, whose influence can be traced in many other Latin American writers. This study aims to tackle one of most recent and relevant Borges’ canonization act: the television programme Borges por Piglia by the TV Pública Argentina made in 2013. It consists of four conferences transmitted massively via television and internet websites, held by the writer Ricardo Piglia. This study set out to examine discourse and communication aspects in these conferences in order to understand value production related to Borges’ work. The paper will analyze Piglia’s discursive ethos, the importance of aesthetic value and the critic’s aim to turn Borges into a close figure for the audience. A comparative strategy will be undertaken to explore Piglia’s conference in relation to other critics’ interventions on Borges. Te present results provide solid evidence to discuss contemporary configurations in Argentinian literary cannon, framed in official cultural policies.Fil: Salas Tonello, Pablo.
