Bilateral taste disorders in patients with Ramsay Hunt syndrome and Bell palsy
2018
OBJECTIVE Ramsay Hunt syndrome (RHS) and Bell palsy (BP) are typically known as facial nerve motor syndromes and are primarily unilateral. The aim of this study was to challenge this assertion, because both conditions are also known to be associated with viruses that typically affect several nerves. METHODS Ten participants with RHS, 12 with BP, all clinically unilateral, and 12 healthy controls were prospectively enrolled. Electrogustometric thresholds were measured bilaterally in the areas of the chorda tympani, the glossopharyngeal, and the major petrosal nerve. Also bilaterally, the taste function was tested using chemogustometry with different tastant concentrations. Again bilaterally,…
Direct synthesis of dimethyl carbonate with supercritical carbon dioxide: characterization of a key organotin oxide intermediate
2006
The direct synthesis of dimethyl carbonate (DMC) using carbon dioxide as solvent and reagent for its fixation to methanol was explored with din-butyldimethoxystannane in order to get insight into the reaction mechanism for activity improvement. Catalytic runs including recycling experiments allowed isolation and characterization by NMR, IR, and single-crystal X-ray diffraction of a new tin complex containing 10 tin atoms. This compound could be prepared independently and is considered as a resting species. The yield of DMC is highest under 20 MPa pressure that fits with a monophasic supercritical medium in agreement with fluid phase equilibria calculations. In line, preliminary kinetics and…
Los predictores clave de la reincidencia en participantes en un programa de intervención para agresores de pareja: un análisis de supervivencia
2020
ABSTRACT Strategies to reduce intimate partner violence against women (IPVAW) can be targeted at different levels. Batterer intervention programs (BIPs) are among the main treatment approaches for IPVAW offenders. The most common outcome used in the evaluation of BIP effectiveness is recidivism. Efforts to increase BIP effectiveness in reducing recidivism should focus on key predictive variables of this outcome. The aim of this study was to identify key predictors of official recidivism from a large set of variables drawn from a sample of IPVAW offenders court-mandated to a community-based BIP (N = 393), with a follow-up period of between 0 and 69 months. To this end, a survival analysis wa…
How can hepatitis C be prevented in the long term?
2007
Abstract Significant advances have been made in preventing HIV infection among injectors but we still know little about preventing hepatitis C (HCV). Both prevalence and incidence of hepatitis C can remain high among IDUs even in the context of widespread implementation of harm reduction programmes. We need to develop new ways to fill the knowledge gap regarding HCV prevention. One way is to learn from the experts—those IDUs who, after long-term injection in social milieus of high hepatitis C prevalence, nonetheless remain uninfected. We describe a recently commenced program of research that focuses on understanding the strategies, behaviours, and environmental factors associated with "stay…
Studentu karcera laika kapsulas
2023
Raksts veltīts unikālam atklājumam Latvijas Universitātes vēsturiskajā Studentu karcerī, kas glabājies kopš 19./20. gs. mijas. Tiek analizētas 3 papirosu paciņas un 1 sērkociņu kastīte no Krievijas impērijas laika, noskaidrojot tā izcelsmi, pielietojumu un zinātnisko novitāti. Atrastie priekšmeti liecina, ka Studentu karcerī ieslēgtie studenti spēja apiet Rīgas Politehnikuma Studentu disciplinēšanas regulā noteikto sodu par smēķēšanu. Priekšmeti arī ir Latvijas industriālās vēstures atstāts mantojums, kas liecina par Baltijas reģiona nozīmi Krievijas impērijas rūpniecības attīstībā.
Validation of the French national health insurance information system as a tool in vaccine safety assessment: Application to febrile convulsions afte…
2013
In the French national health insurance information system (SNIIR-AM), routine records of health claimed reimbursements are linked to hospital admissions for the whole French population. The main focus of this work is the usability of this system for vaccine safety assessment programme. Self-controlled case series analyses were performed using an exhaustive SNIIR-AM extraction of French children aged less than 3 years, to investigate the relationship between MMR immunization and children hospitalizations for febrile convulsions, a well-documented rare adverse event, over 2009-2010. The results suggest a significant increase of febrile convulsions during the 6-11 days period following any MM…
Prevalencia del sexting en adultos jóvenes universitarios: motivación y percepción del riesgo
2021
El sexting es un fenómeno en auge entre adolescentes y adultos jóvenes que consiste en enviar mensajes y/o archivos de carácter sexual a través de los smartphones y las redes sociales. Si bien no existe un claro consenso en su conceptualización, una mala gestión del sexting puede derivar en una serie de peligros como el cyberbullying o la sextorsión. El sexting es un fenómeno clave a la hora de diseñar programas de educativos sexuales en adultos jóvenes El presente estudio tiene como objetivo averiguar el grado de prevalencia del sexting en población adulta joven universitaria. Para ello se administró una serie de instrumentos a 288 estudiantes de entre 18 y 25 años de la Universitat de Val…

Usage and Dose Response of a Mobile Acceptance and Commitment Therapy App: Secondary Analysis of the Intervention Arm of a Randomized Controlled Trial
2016
Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their me…
Biometric variation in three strains of Brachionus plicatilis as a direct response to abiotic variables
1987
Morphometric variation in three clones of Brachionus plicatilis cultured at 20°C, 25°C and 30°C, and 9‰, 12‰ and 24‰ salinity was analysed. Size appeared to be largely under genetic control and this defined the narrow limits within which variation due to abiotic factors could occur. Temperature had a significant effect on size, but affected the three clones differently. The most general effect of temperature was a reduction in size which levelled off as the temperature rose. Of the measurements taken, only distance between the median spines was affected by salinity. An important inter-relationship between the effects of temperature and salinity was also detected.
