Semaglutide reduces fat accumulation in the tongue: A randomized single-blind, pilot study
2021
Abstract Aim We evaluated the effect of the latest GLP-1 RA semaglutide on tongue fat storage in obese women. Design. We conducted a randomized single-blind, pilot study. Methods Twenty-five obese women with polycystic ovary syndrome (PCOS) (33.7 ± 5.3 years, body mass index (BMI) 36.1 ± 3.9 kg/m2, mean ± SD) were randomized to semaglutide 1.0 mg or placebo for 16 weeks. We quantified tongue volume and its fat tissue and fat proportion by magnetic resonance imaging. Results Tongue fat tissue and fat proportion significantly reduced after semaglutide vs placebo (-1.94 ± 5.51 vs. + 3.12 ± 4.87 cm3, p = 0.022, and −0.02 ± 0.07 vs. 0.04 ± 0.06, p = 0.010, respectively). Correlation analysis rev…
Permanent left atrial pacing therapy may improve symptoms in heart failure patients with preserved ejection fraction and atrial dyssynchrony: a pilot…
2012
Aims Our group has recently shown that in some patients, heart failure with preserved ejection fraction (HFPEF) may be explained by ‘atrial dyssynchrony syndrome’ (ADS) due to interatrial conduction delay (IACD), a short left atrioventricular interval (LAVI), and increased left atrial (LA) stiffness. Our primary objective was to evaluate LA pacing therapy as a new treatment to restore left ventricular active filling in patients with no other known causes for HF than ADS. Methods and results Six patients with severe HFPEF with IACD (P wave duration >120 ms in lead II), short LAVI during electrophysiological studies ( 15), and no standard indication for a pacemaker were implanted with a lead …
Ahmed valve, suture-less implantation: A new approach to an easier technique.
2013
Purpose Tissue adhesives have been used in ophthalmology instead of sutures to minimize the operating time. This case series investigated the effectiveness and safety of use of cyanoacrylate in Ahmed valve implantation through pars plana for refractory glaucoma. Patients and methods Seventeen eyes of 17 patients with refractory glaucoma underwent Ahmed valve scleral suture-less implantation through pars plana with a cyanoacrylate suture of the plate. Refractory glaucoma was defined as intraocular pressure (IOP) ≥ 21 mm Hg with antiglaucoma eye drops, good adherence to treatment, and no previous glaucoma surgery. IOP control and development of complications were evaluated during the follow-u…
In Vitro Bioactivity of Astaxanthin and Peptides from Hydrolisates of Shrimp (Parapenaeus longirostris) By-Products: From the Extraction Process to B…
2021
Non-edible parts of crustaceans could be a rich source of valuable bioactive compounds such as the carotenoid astaxanthin and peptides, which have well-recognized beneficial effects. These compounds are widely used in nutraceuticals and pharmaceuticals, and their market is rapidly growing, suggesting the need to find alternative sources. The aim of this work was to set up a pilot-scale protocol for the reutilization of by-products of processed shrimp, in order to address the utilization of this valuable biomass for nutraceutical and pharmaceuticals application, through the extraction of astaxanthin-enriched oil and antioxidant-rich protein hydrolysates. Astaxanthin (AST) was obtained using …
A New Self-Expanding Nitinol Stent (JoStent SelfX) for Palliation of Malignant Biliary Obstruction: a Pilot Study
2004
Background and Study Aims: The JoStent SelfX is a new biliary uncovered self-expanding nitinol stent. The main advantage of this stent in comparison with the gold standard Wallstent is the minimal shortening (< 10%) that occurs during stent deployment. A prospective feasibility study was conducted to evaluate the method of stent implantation and the stent's short-term efficacy. Patients and Methods: Between April 2001 and December 2002, the JoStent SelfX was implanted in 20 patients with inoperable malignant biliary obstructions, mainly caused by pancreatic cancer (12 of 20). All patients underwent sphincterotomy prior to stent insertion. After implantation, laboratory parameters for choles…
Efficacy of Selected Electrical Therapies on Chronic Low Back Pain: A Comparative Clinical Pilot Study
2017
Background: In the currently available research publications on electrical therapy of low back pain, generally no control groups or detailed randomization were used, and such studies were often conducted with relatively small groups of patients, based solely on subjective questionnaires and pain assessment scales (lacking measurement methods to objectify the therapeutic progress). The available literature also lacks a comprehensive and large-scale clinical study. The purpose of this study was to assess the effects of treating low back pain using selected electrotherapy methods. The study assesses the influence of individual electrotherapeutic treatments on reduction of pain, improvement of …
Effects of (un)employment on young couples’ health and life satisfaction
2012
This study investigated effects of employed and unemployed job status on health outcomes with questionnaires in 50 young couples. Analysis of variance revealed higher pessimism, higher stress levels, and lower life satisfaction in couples in which one partner was unemployed. These couples also exhibited more health risk behaviours compared to couples in which both partners were working. The dyadic analysis of data, using an actor-partner interdependence model, demonstrated strong actor and partner effects for male partner's job status. Being unemployed was significantly associated not only with male partner's life satisfaction but also with the life satisfaction of his female partner. In ad…
Low cost-sensors as a real alternative to on-line nitrogen analysers in continuous systems.
2009
This paper is focused on the evaluation of the applicability of low-cost sensors (pH and ORP) versus nutrient analysers for controlling biological nitrogen removal in WWTPs. A nutrient removal pilot plant located in Carraixet WWTP (Valencia, Spain) that is equipped with a significant number of nutrient analysers and low-cost sensors was used. The relations between reliable, cheap on-line sensors such as pH and ORP (located in anaerobic, anoxic and aerobic zones) and the nitrification/denitrification processes are provided. The nitrification process can be evaluated by measuring the pH difference between the first and last aerobic zones. The denitrification process can be evaluated by measur…
Hybrid activated sludge/biofilm process for the treatment of municipal wastewater in a cold climate region: a case study.
2011
A hybrid activated sludge/biofilm process was investigated for wastewater treatment in a cold climate region. This process, which contains both suspended biomass and biofilm, usually referred as IFAS process, is created by introducing plastic elements as biofilm carrier media into a conventional activated sludge reactor. In the present study, a hybrid process, composed of an activated sludge and a moving bed biofilm reactor was used. The aim of this paper has been to investigate the performances of a hybrid process, and in particular to gain insight the nitrification process, when operated at relatively low MLSS SRT and low temperatures. The results of a pilot-scale study carried out at the…
Post-prandial alterations in LDL size and subclasses in patients with growth hormone deficiency
2008
Abstract Objective Several studies have suggested that lipoproteins generated during the post-prandial phase are highly atherogenic, with modifications in low-density lipoproteins (LDL) size and density. In the present study we assessed post-prandial variations in LDL size and subclasses in patients with growth hormone deficiency (GHD). Design We studied in 12 hypopituitary patients with GHD and 10 healthy control subjects matched for gender, age and body mass index (BMI) post-prandial variations after a standardized meal consisting of 35% fat, 45% carbohydrate and 20% of protein (Clinutren Mix ® , Nestle) and containing calories corresponding to 1/3 of estimated basal metabolic rate.
