Early Spot Urinary Sodium and Diuretic Efficiency in Acute Heart Failure and Concomitant Renal Dysfunction
2020
<b><i>Objective:</i></b> In acute heart failure (AHF), early assessment of spot urinary sodium (U<sub>Na</sub>) has emerged as a useful biomarker for risk stratification and monitoring. The objective of this study was to investigate (a) whether early spot U<sub>Na</sub> predicts 24-h diuretic efficiency and (b) the clinical factors associated with early spot U<sub>Na</sub> in patients with AHF and concomitant renal dysfunction (RD). <b><i>Methods:</i></b> This is a post hoc analysis of the IMPROVE-HF trial, in which 160 patients with AHF and RD (estimated glomerular filtrate rate [eGFR] &#x3c;60 mL/min/1…
Newborn hearing-screening project using transient evoked otoacoustic emissions: western sicily experience
2006
Summary Objective To study the incidence of congenital sensorineural hearing loss in all newborns introducing a screen test with a protocol no expensive, with a good “screen sensitivity” that could let an earlier identification of hearing impairment beginning early intervention by 2 months of age and increasing the probability of having language development within the normal range of development. Methods The study was conducted in Sciacca hospital from the beginning of 2003 to our days and was carried out with transient evoked otoacoustic emission using the criteria for PASS or RETEST and considering eventual prenatal and perinatal risk factors. All the newborns were divided into four group…
Does the origin of ablated premature ventricular contractions determine the level of left ventricular function improvement?
2020
Background: Premature ventricular contractions (PVCs) are associated with tachycardiomyopathy and high mortality rate. The treatment depends on the engaged ventricle. For PVCs originating from the right outflow tract (OT), radiofrequency catheter ablation (RFCA) is recommended (class IB‑R recommendation) in preference to pharmacotherapy. In those originating from the left ventricle, ablation is a class IIa B‑NR recommendation. Aims: The aim of the study was to assess the success of RFCA of PVCs based on arrhythmia origin. Methods: A total of 110 consecutive patients with monomorphic PVCs referred for ablation were enrolled and divided according to the site of ablation to the OT group and th…
Post-synoviorthesis rehabilitation in haemophilia.
2001
The efficacy of radiosynoviorthesis in the management of chronic haemophilic synovitis has been proven. Like replacement therapy, however, this procedure has no effect on muscle strength or endurance, range of movement, coordination, or the patient's physical condition in general. All the factors just enumerated are essential for the recovery and maintenance of the haemophiliac's quality of life. That is why rehabilitation and physiotherapy are so important, since no medical therapy or surgical procedure are by themselves capable of preventing disabilities.
Treatment strategies and outcome of the exstrophy–epispadias complex in germany: data from the german CURE-Net
2020
Introduction: To evaluate the impact of reconstructive strategies and post-operative management on short- and long-term surgical outcome and complications of classical bladder exstrophy (CBE) patients' comprehensive data of the multicenter German-wide Network for Congenital Uro-Rectal malformations (CURE-Net) were analyzed. Methods: Descriptive analyses were performed between 34 prospectively collected CBE patients born since 2009, median 3 months old [interquartile range (IQR), 2–4 months], and 113 cross-sectional patients, median 12 years old (IQR, 6–21 years). Results: The majority of included individuals were males (67%). Sixty-eight percent of the prospectively observed and 53% of the …
Isokinetic Profile of Elite Serbian Female Judoists
2021
Elite judo athletes undergo vigorous training to achieve outstanding results. In pursuit of achieving competitive success, the occurrence of injuries amongst judo athletes is not rare. The study aimed to perform a knee flexors and extensors isokinetic torque analysis in elite female judo athletes. Fifty-eight elite female judo athletes of the Serbian national team (21.02 ± 3.11 years
Stress Hyperglycemia as Predictive Factor of Recurrence in Children with Febrile Seizures
2020
Stress hyperglycemia and hyperlactatemia are commonly referred to as markers of stress severity and poor outcome in children with severe acute illness or febrile seizures. Our prospective study aimed to explore the risk factors for stress hyperglycemia and the predictive value of stress hyperglycemia for febrile seizure recurrence. We evaluated as risk factors for blood glucose level, serum lactate, acid&ndash
Updating the Philosophy of Middle-Range Theories : Implications for IS
2018
Merton’s concepts of middle-range theories (MRTs) and grand theories (GTs) are widely mentioned in information systems (IS) theorizing literature. On one hand, numerous IS authors claim that MRTs are common in IS or that design science theories are MRTs. On the other hand, others report that too much focus is placed on GTs (instead of MRTs) in IS. Moreover, MRTs and GTs have acquired a normative role in IS. Given such disagreements and the normative role of MRTs and GTs, there is a need to examine what Merton’s GT and MRT are. The aim of this paper is to start such a discussion by providing an interpretation of Merton’s GT and MRT. We contest many IS views on Merton. We also suggest that Me…
Localization of Multi-Class On-Road and Aerial Targets Using mmWave FMCW Radar
2021
mmWave radars play a vital role in autonomous systems, such as unmanned aerial vehicles (UAVs), unmanned surface vehicles (USVs), ground station control and monitoring systems. The challenging task when using mmWave radars is to estimate the accurate angle of arrival (AoA) of the targets, due to the limited number of receivers. In this paper, we present a novel AoA estimation technique, using mmWave FMCW radars operating in the frequency range 77–81 GHz by utilizing the mechanical rotation. Rotating the radar also increases the field of view in both azimuth and elevation. The proposed method estimates the AoA of the targets, using only a single transmitter and receiver. The measurements are…
Classification of Targets Using Statistical Features from Range FFT of mmWave FMCW Radars
2021
Radars with mmWave frequency modulated continuous wave (FMCW) technology accurately estimate the range and velocity of targets in their field of view (FoV). The targeted angle of arrival (AoA) estimation can be improved by increasing receiving antennas or by using multiple-input multiple-output (MIMO). However, obtaining target features such as target type remains challenging. In this paper, we present a novel target classification method based on machine learning and features extracted from a range fast Fourier transform (FFT) profile by using mmWave FMCW radars operating in the frequency range of 77–81 GHz. The measurements are carried out in a variety of realistic situations, including p…
