Impact of Extended-Criteria Donor Liver Grafts on Benchmark Metrics of Clinical Outcome After Liver Transplantation: A Single Center Experience.
2020
Abstract Background The adoption of extended criteria for donors remains the best strategy to widen the pool of available liver graft against the chronic shortage of donors. Benchmarking in liver transplantation (LT) offers the unprecedented opportunity to compare clinical outcome measures to a set of validated reference values. We aimed to evaluate the impact of marginal grafts usage in a cohort of low-risk benchmark cases from an area with a very low rate of deceased donation. Methods A cohort of low-risk benchmark cases was identified from all adult patients who underwent LT at our center. Among these patients, those transplanted with a graft from an extended-criteria donor (ECD) were id…
Exercise intensity progression for exercises performed on unstable and stable platforms based on ankle muscle activation.
2013
Ankle sprains are a common sports injury. The literature focuses on the application of neuromuscular training for the improvement of balance, injury prevention and rehabilitation. However, there is a dearth of knowledge about the appropriate prescription of exercises using unstable platforms and surfaces. The purpose of this study was to devise an ankle rehabilitation or training program with exercise progression based on the extent of muscle activation, employing platforms with different levels of stability and additional resistance. A descriptive study of electromyography (EMG) during ankle exercises was performed with a convenience sample of healthy subjects. Forty-four subjects complete…
Gravimetrically Controlled Efficacy of Subcorial Curettage: A Prospective Study for Treatment of Axillary Hyperhidrosis
2002
Botulinum toxin A (BTX-A) proved to be effective for the treatment of axillary hyperhidrosis by means of gravimetry. Quantitatively controlled studies for surgical treatment are lacking so far.To prospectively test the efficacy of subcorial axillary curettage by gravimetric evaluation of pre- and postsurgical sweat rates.Conservatively pretreated patients received subcorial curettage under tumescent local anesthesia using a sharp spoon. Sweat rates of each axilla were determined gravimetrically before and 4-8 weeks after surgery. Evaluation was performed with respect to baseline sweat rates greater than 50 mg/min (group A), greater than 25 and less than 50 mg/min (group B), and less than 25…
Severe herpes simplex virus type-I infections after dental procedures
2010
Background: Recurrences of herpes labialis (RHL) may be triggered by systemic factors, including stress, menses, and fever. Local stimuli, such as lip injury or sunlight exposure are also associated to RHL. Dental extraction has also been reported as triggering event. Case reports: Seven otherwise healthy patients are presented with severe and extensive RHL occurring about 2-3 days after dental extraction under local anaesthesia. Immunohistochemistry on smears and immunofluorescence on cell culture identified herpes simplex virus type I (HSV-I). Five patients reported more severe prodromal signs than usual. Although all the patients suffered from RHL, none had previously experienced RHL aft…
Passive exposure to speech sounds modifies change detection brain responses in adults
2019
In early life auditory discrimination ability can be enhanced by passive sound exposure. In contrast, in adulthood passive exposure seems to be insufficient to promote discrimination ability, but this has been tested only with a single short exposure session in humans. We tested whether passive exposure to unfamiliar auditory stimuli can result in enhanced cortical discrimination ability and change detection in adult humans, and whether the possible learning effect generalizes to different stimuli. To address these issues, we exposed adult Finnish participants to Chinese lexical tones passively for 2 h per day on 4 consecutive days. Behavioral responses and the brain's event-related potenti…
Infection with human herpes virus type 8 in an area at high prevalence for hepatitis C virus infection in southern Italy
2004
Summary. The Campania Region is a geographical area of southern Italy characterized by high incidence rates of hepatocellular carcinoma and of classic Kaposi's sarcoma. Epidemiological investigations carried out among different population groups in this region have found high prevalence rates of both hepatitis C virus (HCV) and human herpesvirus type 8 (HHV-8). To assess co-infection rates of HCV and HHV-8, we carried out a cross-sectional seroepidemiological study prevalence in Pomigliano d'Arco, a Health District of Campania located 20 km away from Naples. The overall rate of HCV/HHV-8 co-infection was 3.1%, 3.5% among men and 2.7% among women. No difference emerged in the HCV/HHV-8 co-i…
Effects of post-extinction l-DOPA administration on the spontaneous recovery and reinstatement of fear in a human fMRI study
2015
Relapse is a pertinent problem in the treatment of anxiety disorders. In the laboratory, relapse is modeled as return of conditioned fear responses after successful fear extinction and is explained by insufficient retrieval and/or expression of the fear-inhibitory extinction memory that is generated during extinction learning. We have shown in mice and humans that return of fear can be prevented by administration of a single dose of the dopamine precursor l-3,4-dihydroxyphenylalanine (l-DOPA) immediately after extinction. In mice, this effect could be attributed to an enhancement of extinction memory consolidation. In our human study, we could not exclude that l-DOPA might have acted by int…
Force in the Achilles Tendon During Walking With Ankle Foot Orthosis
2009
Background Ankle foot orthoses are used for postoperative treatment of Achilles tendon ruptures and decrease calf muscle electromyography activity during walking. Hypothesis Achilles tendon load decreases with increased restriction of dorsiflexion and is associated with decreased triceps surae activity. Study Design Controlled laboratory study. Methods In 8 subjects, the maximum force and rate of force development in the Achilles tendon were measured with an optic fiber technique, and the activity of the gastrocnemius, soleus, and tibialis anterior muscles was recorded using electromyography. Trial conditions were walking barefoot and wearing an ankle-foot orthoses set in 3 different positi…
Retrospective Cohort Study of Cancer Mortality at the Minsk Leather Tannery
2006
The cohort of 768 workers who were actively employed for a minimum of 6 months and died was retrospectively followed from 1 January 1953 to 31 December 2000. There were 328 women and 440 men observed. Proportionate mortality ratios (PMRs) were calculated using the Minsk-city population mortality proportions to generate expected numbers. The significant excess of pancreatic cancer (PMR=366%; 95%CI=134-800) and melanoma and skin cancer (PMR=455%; 95% CI=123-1,164) in women-workers of Dyeing and stuffing workshops was shown. The significantly high mortality from pancreatic cancer among Dyeing and stuffing workshops' female workers hired and discharged between 1958 and 1984 (PMR=1,024%; 95% CI=…
The role of Posterior Parietal Cortex in spatial representation of time: a TMS study.
2011
1. Introduction. The existence of a spatial representation of time, where temporal intervals are represented on a mental temporal line (MTL), oriented in ascending order from left to right, was demonstrated manipulating spatial attention by means of Prismatic Adaptation (PA). In young healthy subjects, prisms adaptation inducing a rightward shift of spatialattention produced an overestimation of time intervals, whereas prisms adaptation inducing a leftward shift of spatialattention produced an underestimation of time intervals [4]. The aimof the present study was to investigate the neural basis mediating the effects of PA on spatial time representation. PosteriorParietalCortex (PPC) is the …
