Project description:Ultrasound (US)-guided percutaneous needle electrolysis (PNE) is a novel minimally invasive approach which consists of the application of a galvanic current through an acupuncture needle.To evaluate the clinical and ultrasonographic effectiveness of a multimodal programme (PNE, eccentric exercise (EccEx) and stretching) in the short term for patients with chronic lateral epicondylitis, and to determine whether the clinical outcomes achieved decline over time.A one-way repeated measures study was performed in a clinical setting in 36 patients presenting with lateral epicondylitis. The patients received one session of US-guided PNE per week over 4-6?weeks, associated with a home programme of EccEx and stretching. The main outcome measures were severity of pain, disability (Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire), structural tendon changes (US), hypervascularity and patients' perceptions of overall outcome. Measurements at 6, 26 and 52?weeks follow-up included recurrence rates (increase in severity of pain or disability compared with discharge), perception of overall outcome and success rates.All outcome measures registered significant improvements between pre-intervention and discharge. Most patients (n=30, 83.3%) rated the overall outcome as 'successful' at 6?weeks. The ultrasonographic findings showed that the hypoechoic regions and hypervascularity of the extensor carpi radialis brevis changed significantly. At 26 and 52?weeks, all participants (n=32) perceived a 'successful' outcome. Recurrence rates were null after discharge and at follow-up at 6, 26 and 52?weeks.Symptoms and degenerative structural changes of chronic lateral epicondylitis are reduced after US-guided PNE associated with EccEx and stretching, with encouragingly low recurrences in the mid to long term.ClinicalTrials.gov identifier: NCT02085928.

Project description:The Commando procedure is challenging, and aims to replace the mitral valve, the aortic valve and the aortic mitral curtain, when the latter is severely affected by pathological processes (such as infective endocarditis or massive calcification). Given the high complexity, it is seldomly performed. We aim to review the literature on early (hospitalization and up to 30 days) and long-term (at least 3 years of follow-up) results. Bibliographical research was performed on PubMed and Cochrane with a dedicated string. Papers regarding double valve replacement or repair in the context of aortic mitral curtain disease were included. The metaprop function was used to assess early survival and complications (pacemaker implantation, stroke and bleeding). Nine papers (540 patients, median follow-up 41 (IQR 24.5-51.5) months) were included in the study. Pooled proportion of early mortality, stroke, pacemaker implant and REDO for bleeding were, respectively 16.2%, 7.8%, 25.1% and 13.1%. The long-term survival rate ranged from 50% to 92.2%. Freedom from re-intervention was as high as 90.9% when the endocarditis was not the first etiology and 78.6% in case of valvular infection (one author had 100%). Freedom from IE recurrences reached 85% at 10 years. Despite the high mortality, the rates of re-intervention and infective endocarditis recurrences following the Commando procedure are satisfactory and confirm the need for an aggressive strategy to improve long-term outcomes.

Project description:X-linked hypohidrotic ectodermal dysplasia (XLHED), caused by a genetic deficiency of ectodysplasin A1 (EDA1), is a rare developmental disorder of ectodermal derivatives such as hair, sweat glands, and teeth. The absence of sweat glands and perspiration can evoke life-threatening hyperthermia. As molecular genetic findings are not always conclusive, the concentrations of circulating EDA1 may help to distinguish between total and partial EDA1 deficiencies. We previously treated nine male patients with obvious signs of XLHED with a recombinant EDA1 replacement protein, Fc-EDA, either shortly after birth (n = 3) or by prenatal administration in gestational week 26 and beyond (n = 6). Here, we present the long-term follow-up for up to six years. In patients who had received Fc-EDA after birth, neither sweat glands nor sweating ability were detected at the age of 12-60 months. In contrast, prenatal EDA1 replacement resulted in ample sweat gland development and pilocarpine-inducible sweating in all treated subjects, who also attained more permanent teeth than their untreated affected relatives. Normal perspiration has persisted for six years in the two oldest boys treated repeatedly with Fc-EDA in utero. When they had a sauna, adequate thermoregulation was evidenced. Lower sweat production after single prenatal dosing may indicate a dose-response relationship. The absence of circulating EDA1 in five prenatally treated subjects proved that these children would have been unable to perspire if they had been left untreated. The sixth infant was shown to produce an EDA1 molecule that, albeit interacting with its cognate receptor, cannot activate EDA1 signaling. In conclusion, a causal treatment of XLHED before birth is feasible.

Project description:ObjectivesOur goal was to study long-term observed and relative survival after first-time aortic valve replacement surgery with or without concomitant coronary artery bypass surgery with reference to valve morphology (i.e. bicuspid vs tricuspid).MethodsConsecutive patients (n = 5086) from 3 Swedish hospitals, operated on between 1 January 2005 and 31 December 2016, were included. The 30-day mortality (n = 116, 2.3%) was excluded from the analysis of long-term observed and relative survival (n = 4970). Observed survival was analysed using Cox regression. Relative survival was calculated as the ratio between observed and expected survival based on data from the general Swedish population, matched for age, sex and calendar year. Risk factors for death were explored using multivariable analysis.ResultsDuring the follow-up (median 4.7 years) period, 1157 (23%) patients died. Observed survival excluding 30-day mortality was 96.6%, 82.7% and 57.6% after 1, 5 and 10 years. Compared with the general Swedish population, the relative 1-, 5- and 10-year survival rates were 99.0%, 97.5% and 89.0%. Bicuspid morphology was independently associated with higher observed and relative long-term survival. Renal dysfunction, diabetes, chronic obstructive pulmonary disease, heart failure, smoking and atrial fibrillation were associated with higher long-term mortality. Combined surgery was not associated with higher observed or relative mortality.ConclusionsPatients with a bicuspid morphology had better prognosis, matching that of the general population. With increased age, long-term relative survival compared favourably with survival in the general Swedish population. Adding coronary artery bypass surgery to an aortic valve replacement procedure did not affect long-term outcome.

Project description:Background and Purpose Midcarpal arthrodesis is a well-accepted treatment option for advanced carpal collapse. In this study, we retrospectively assessed survival, analyzed complications and reviewed the long-term follow-up after midcarpal fusion. Materials and Methods The computerized medical records of 572 patients who had undergone 594 four-corner fusions between 1992 and 2001 were explored. Furthermore 56 patients with 60 midcarpal fusions were randomized for clinical and radiological follow-up at a mean of 14.7 years. Results Forty midcarpal fusions (6.7%) had to be converted into complete wrist arthrodesis. The reasons were ongoing pain in spite of a well-healed midcarpal fusion (31) or nonunion (9). Sixty-three patients (11%) required revision surgery because of nonunion (22), hematoma (8), wound infection (3) or persisting pain (31). In clinical follow-up the mean Disabilities of the Arm, Shoulder, and Hand (DASH) score was 20.4. Pain at rest was infrequent, a mild increase with daily activity was complained of (mean visual analog scale [VAS] 3.3). The mean active range of wrist motion for extension and flexion, ulnar and radial deviation and supination and pronation reached 62.5%, 68.4%, 94.7%, and mean grip strength 84.9% of the unaffected side. All patients had radiographic abnormalities, with frequent evidence of osteoarthritis of the lunate fossa. Patients with preserved carpal height appeared to have less pain, better DASH scores and a better range of motion. Conclusions The midcarpal arthrodesis is a long-lasting treatment option for advanced carpal collapse and has good long-term results. Level of Evidence Level IV, Therapeutic study.

Project description:The US Food and Drug Administration adopted labeling for nicotine patches to allow use beyond the standard 8 weeks. This decision was based in part on data showing increased efficacy for 24 weeks of treatment. Few studies have examined whether the use of nicotine patches beyond 24 weeks provides additional therapeutic benefit.To compare 8 (standard), 24 (extended), and 52 (maintenance) weeks of nicotine patch treatment for promoting tobacco abstinence.We recruited 525 treatment-seeking smokers for a randomized clinical trial conducted from June 22, 2009, through April 15, 2014, through 2 universities.Smokers received 12 smoking cessation behavioral counseling sessions and were randomized to 8, 24, or 52 weeks of nicotine patch treatment.The primary outcome was 7-day point prevalence abstinence, confirmed with breath levels of carbon monoxide at 6 and 12 months (intention to treat).At 24 weeks, 21.7% of participants in the standard treatment arm were abstinent, compared with 27.2% of participants in the extended and maintenance treatment arms (?(2)(1)?= 1.98; P =?.17). In a multivariate model controlled for covariates, participants in the extended and maintenance treatment arms reported significantly greater abstinence rates at 24 weeks compared with participants in the standard treatment arm (odds ratio [OR], 1.70 [95% CI, 1.03-2.81]; P =?.04), had a longer duration of abstinence until relapse (? = 21.30 [95% CI, 10.30-32.25]; P <?.001), reported smoking fewer cigarettes per day if not abstinent (mean [SD], 5.8 [5.3] vs 6.4 [5.1] cigarettes per day; ? = 0.43 [95% CI, 0.06-0.82]; P =?.02), and reported more abstinent days (mean [SD], 80.5 [38.1] vs 68.2 [43.7] days; OR, 1.55 [95% CI, 1.06-2.26]; P =?.02). At 52 weeks, participants in the maintenance treatment arm did not report significantly greater abstinence rates compared with participants in the standard and extended treatment arms (20.3% vs 23.8%; OR, 1.17 [95% CI, 0.69-1.98]; P =?.57). Similarly, we found no difference in week 52 abstinence rates between participants in the extended and standard treatment arms (26.0% vs 21.7%; OR, 1.33 [95% CI, 0.72-2.45]; P =?.36). Treatment duration was not associated with any adverse effects or adherence to the counseling regimen, but participants in the maintenance treatment arm reported lower adherence to the nicotine patch regimen compared with those in the standard and extended treatment arms (mean [SD], 3.94 [2.5], 4.61 [2.0], and 4.7 [2.4] patches/wk, respectively; F2,522 = 6.03; P =?.003).The findings support the safety of long-term use of nicotine patch treatment, although they do not support efficacy beyond 24 weeks of treatment in a broad group of smokers.clinicaltrials.gov Identifier: NCT01047527.

Project description:BackgroundTranscatheter aortic valve replacement (TAVR) has become the standard of care in the majority of patients with symptomatic severe aortic stenosis. Data on long-term mortality and durability of transcatheter heart valves (THVs) beyond 5 years are limited. Our study aimed to assess elderly and high-risk patients' long-term outcomes treated with TAVR in a prospective single-centre registry focusing on the durability of THVs.MethodsWe included 795 patients with severe calcific aortic stenosis treated by transfemoral TAVR between 2006 and 2011. Echocardiography was performed at baseline; discharge; 1 year; and afterward, annually, until the longest available follow-up. Mortality rates were estimated for 1, 5, 6, 7, and 8 years. The rates of structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) were assessed in accordance with consensus definitions. Outcome measures were adjudicated according to Valve Academic Research Consortium-2 (VARC-2).ResultsMedian (interquartile range) follow-up time was 1345 (316; 2015) days. One-year, 5-year, 6-year, 7-year, and 8-year overall mortality was 25.4%, 59.0%, 64.6%, 67.9%, and 69.2%, respectively. At 8 years, no significant differences in mortality were found comparing self-expanding vs balloon-expandable valves (69.5% vs 68.0%, P = 0.709) and postdilatation (PD) vs no-PD (69.4% vs 69.2%, P = 0.363). SVD was detected in 26 patients (3.3%), and 19 (2.4%) of the 795 patients had evidence of BVF during follow-up.ConclusionsOur study demonstrates good long-term results for high-risk patients who were alive up to 8 years after TAVR.

Project description:The Lateral Habenula (LHb) is a small brain structure that codifies negative motivational value and has been related to major depression. It has been shown recently that LHb activation is sufficient to induce aversive associative learning; however the key question about whether LHb activation is required for an aversive memory to be formed has not been addressed. In this article we studied the function of the LHb in memory formation using the Inhibitory Avoidance task (IA). We found that LHb inactivation during IA training does not disrupt memory when assessed 24 h after, but abolishes it 7 days later, indicating that LHb activity during memory acquisition is not necessary for memory formation, but regulates its temporal stability. These effects suggest that LHb inactivation modifies subjective perception of the training experience.

Project description:BackgroundA randomized, placebo-controlled phase III study (AB10015) previously demonstrated that orally administered masitinib (4.5 mg/kg/day) slowed rate of functional decline, with acceptable safety, in amyotrophic lateral sclerosis (ALS) patients having an ALS Functional Rating Scale-revised (ALSFRS-R) progression rate from disease onset to baseline of <1.1 points/month. Here we assess long-term overall survival (OS) data of all participants from study AB10015 and test whether a signal in OS is evident in an enriched patient population similar to that prospectively defined for confirmatory study AB19001.MethodsSurvival status of all patients originally randomized in AB10015 was collected from participating investigational sites. Survival analysis (using the multivariate log-rank test and Cox proportional hazards model, with stratification factors as covariates) was performed on the intention-to-treat population and enriched subgroups, which were defined according to initial randomization, baseline ALSFRS-R progression rate and baseline disease severity.ResultsA significant survival benefit of 25 months (p = 0.037) and 47% reduced risk of death (p = 0.025) was observed for patients receiving 4.5 mg/kg/day masitinib (n = 45) versus placebo (n = 62) in an enriched cohort with ⩾2 on each baseline ALSFRS-R individual component score (i.e. prior to any complete loss or severe impairment of functionality) and post-onset ALSFRS-R progression rate <1.1 (i.e. exclusion of very fast progressors) [median OS of 69 versus 44 months, respectively; hazard ratio, 0.53 [95% CI (0.31-0.92)]]. This corresponds to the population enrolled in confirmatory phase III study, AB19001.ConclusionsAnalysis of long-term OS (75 months average follow-up from diagnosis) indicates that oral masitinib (4.5 mg/kg/day) could prolong survival by over 2 years as compared with placebo, provided that treatment starts prior to severe impairment of functionality.This trial was registered at www.ClinicalTrials.gov under identifier NCT02588677 (28 October 2015).

Project description:For patients with severe aortic stenosis (AS) at extreme surgical risk, transcatheter aortic valve replacement (TAVR) leads to improved survival and health status when compared with medical therapy. Whether the early health status benefits of TAVR in these patients are sustained beyond 1 year of follow-up is unknown.Six hundred thirty-nine patients with severe AS at extreme surgical risk underwent TAVR in the CoreValve US Extreme Risk Pivotal trial. Health status was evaluated at baseline and at 1, 6, 12, 24, and 36 months using the Kansas City Cardiomyopathy Questionnaire (KCCQ), the Short-Form-12, and the EuroQoL-5D. Analyses were performed using pattern mixture models to account for both death and missing data and were stratified by iliofemoral (IF) and non-iliofemoral (non-IF) access. After TAVR, there was substantial health status improvement in disease-specific and generic scales by 6 to 12 months. Although there were small declines in health status after 12 months, the initial benefits of TAVR were largely sustained through 3 years for both IF and non-IF cohorts (change from baseline in KCCQ Overall Summary score 19.0 points in IF patients and 14.9 points in non-IF patients; P<.01 for both comparisons). Among surviving patients, clinically meaningful (?10 point) improvements in the KCCQ Overall Summary Score at 3 years were observed in 85.0% and 83.4% of IF and non-IF patients respectively.Among extreme risk patients with severe AS, TAVR resulted in large initial health status benefits that were sustained through 3-year follow-up. Although late mortality was high in this population, these findings demonstrate that TAVR offers substantial and durable health status improvements for surviving patients.
