Bone status in adolescents and young adults with type 1 diabetes: a 10-year longitudinal study
2020
Introduction: This study presents a 10-year longitudinal assessment of bone status in adolescents and young adults with type 1 diabetes (T1D). Material and methods: Thirty-two patients (12 female, aged 20.5 ± 3.93 years, T1D duration 13.9 ± 1.97 years) were studied using quantitative ultrasound (QUS) and dual-energy X-ray absorptiometry (DXA). Standard deviation scores (SDS) for these results were calculated. The following clinical parameters were analysed: sex, age, T1D duration, anthropometric parameters, daily insulin requirement (DIR), mean glycated haemoglobin (HbA1c) in the year preceding the examination, medication other than insulin, history of bone fractures, and comorbidities. Res…
Trends in modes of death in heart failure over the last two decades: less sudden death but cancer deaths on the rise.
2019
AIMS Better management of heart failure (HF) over the past two decades has improved survival, mainly by reducing the incidence of death due to cardiovascular (CV) causes. Deaths due to non-CV causes, particularly cancer, may be increasing. This study explored the modes of death of consecutive patients who attended a HF clinic over 17 years. METHODS AND RESULTS A total of 935 deaths were ascertained from 2002 to 2018 among 1876 patients (mean age 65.8 ± 12.5 years, 75% men, left ventricular ejection fraction < 50%) admitted to our HF clinic. Median follow-up was 4.2 years [1.9-7.8]. Mode of death was curated from patient health records and verified by the Catalan and Spanish health system da…
Maternal Iodine Status During Pregnancy Is Not Consistently Associated with Attention-Deficit Hyperactivity Disorder or Autistic Traits in Children
2020
Background: Severe iodine deficiency during pregnancy can cause intellectual disability, presumably through inadequate placental transfer of maternal thyroid hormone to the fetus. The association between mild-to-moderate iodine deficiency and child neurodevelopmental problems is not well understood. Objectives: We investigated the association of maternal iodine status during pregnancy with child attention-deficit hyperactivity disorder (ADHD) and autistic traits. Methods: This was a collaborative study of 3 population-based birth cohorts: Generation R (n = 1634), INfancia y Medio Ambiente (n = 1293), and the Avon Longitudinal Study of Parents and Children (n = 2619). Exclusion criteria were…
Validation of the Multicultural Personality Questionnaire Short Form (MPQ-SF) for use in the context of international education
2020
The Multicultural Personality Questionnaire (MPQ) is one of the most widely used instruments for measuring individuals’ intercultural competences. The original version consists of 91 items, divided into five subscales, and has been shown to predict attitudes, behavior, and outcomes in a variety of intercultural contexts. Recently, a 40-item short form of the MPQ was developed (MPQ-SF), which may be particularly useful in settings in which time or survey space are limited, or where respondent drop-out is likely to occur. For example, the MPQ-SF would be a valuable tool for assessing longitudinal development of multicultural personality traits in training or educational settings. A prerequisi…
The role of pregnenolone sulphate in spatial orientation-acquisition and retention: An interplay between cognitive potentiation and mood regulation
2013
Abstract Neurosteroids can alter neuronal excitability interacting with specific neurotransmitter receptors, thus affecting several functions such as cognition and emotionality. In this study, we investigated, in adult male rats, the effects of the acute administration of pregnenolone-sulfate (PREGS) (10 mg/Kg, s. c.) on cognitive processes using the Can test, a non aversive spatial/visual task which allows the assessment of spatial information-acquisition during the baseline training, and of memory retention in the longitudinal study. Furthermore, on the basis of PREGS pharmacological profile, the modulation of depressive-like behaviour was also evaluated in the forced swim test (FST). Our…
HIDRAdisk: validation of an innovative visual tool to assess the burden of hidradenitis suppurativa
2019
Background: Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disease characterized by painful inflamed nodules, recurrent abscesses and fistulas located in apocrine gland–bearing body sites. The negative impact of HS on patient's quality of life (QoL) has been reported to be greater than other dermatologic conditions as psoriasis and atopic eczema, and its improvement is an important goal in disease management. Nowadays, there are no specific validated QoL instruments available for HS and generic dermatologic questionnaires are used. Objective: The objective of this study was to demonstrate the validity, reliability and responsiveness of HIDRAdisk, a new innovative t…
Examining the course of hallucinatory experiences in children and adolescents: A systematic review
2011
Abstract Background Childhood and adolescence represent the periods during which hallucinatory experiences occur at the greatest prevalence, and also constitute a critical window of vulnerability for the pathogenesis of psychotic disorders. The longitudinal course of hallucinatory experiences during late childhood and adolescence, as well as their relationship to psychotic disorders, has never been the subject of review. Methods We followed the PRISMA guidelines for conducting systematic reviews and combined the use of electronic and manual systematic search methods. Data were extracted upon pre-defined requested items and were analyzed using several epidemiological measures. The interpreta…
Patterns and predictors of low physical activity in patients with stable COPD: a longitudinal study
2020
Background: Despite the frequency and negative impact of low physical activity among patients with chronic obstructive pulmonary disease (COPD), little is known about how it persists and remits over time or the factors predicting new states of low physical activity. The aim of the study was to determine the probability of a transition between states of low and nonlow physical activity in a cohort of patients with stable COPD followed for 2 years. We also investigated different potentially modifiable factors to determine whether they can predict new states of low physical activity. Methods: We prospectively included 137 patients with stable COPD (mean age 66.9 ± 8.3 years). Physical activity…
GOLD 2017 treatment pathways in ‘real life’: An analysis of the DACCORD observational study
2017
Abstract Introduction The 2017 update to the Global Initiative for Obstructive Lung Disease (GOLD) strategy document includes recommendations for treatment intensification or step-down in chronic obstructive pulmonary disease (COPD), although recognises that limited supporting information is available. DACCORD is an ongoing observational, non-interventional study, recruiting patients following COPD maintenance treatment change or initiation, a subset of whom were receiving a long-acting β2-agonist (LABA) plus a long-acting muscarinic antagonist (LAMA) fixed-dose combination (FDC) on entry. Since there were no requirements in terms of prior medication (and no washout before commencing LABA/L…
Long-term variations of arterial stiffness in patients with obesity and obstructive sleep apnea treated with continuous positive airway pressure
2020
BackgroundObstructive sleep apnea (OSA) is associated with cardiovascular co-morbidities and mortality. Arterial stiffness is an independent predictor of cardiovascular risk and mortality, and is influenced by the presence of OSA and related comorbidities. There is a paucity of data regarding long-term evolution of arterial stiffness in CPAP-treated OSA patients. We aimed to prospectively study long term PWV variations and determinants of PWV deterioration.MethodsIn a prospective obese OSA cohort, at time of diagnosis and after several years of follow-up we collected arterial stiffness measured by carotid-femoral pulse wave velocity (PWV), clinical and metabolic parameters, and CPAP adheren…
