Factors Associated with Nonsuppression of HIV Infection in the Spanish VACH Cohort.

2020

We aim to determine the prevalence of HIV nonsuppression and factors associated with it. This is a cross-sectional multicenter study carried out in January 2016 with data of the VACH Cohort, a registry participated by 23 hospitals from most regions of Spain. The prevalence of HIV nonsuppression, defined as HIV RNA ≥200 copies/mL, is documented. The possible association of HIV nonsuppression with sociodemographic and clinical variables is assessed with a logistic regression analysis. A total of 30,843 adult patients are included; 7,358 of them (23.86%) have nonsuppressed HIV. An association is found between nonsuppression of HIV and the following variables: lower body mass index, lower age o…

Factors predicting distress among parents/caregivers of children with neurological disease and home enteral nutrition

2013

Background & aims Caregivers of children with chronic diseases included in a home enteral nutrition (HEN) programme are at risk of experiencing a feeling of burden, high level of anxiety and psychological distress. The aims of this study were: first, to examine the prevalence of symptoms of anxiety–depression in caregivers of children with neurological diseases requiring HEN by gastrostomy tube (GT); second, to compare the characteristics of caregivers with high or low risk of exhibiting symptoms of anxiety–depression; and third, to investigate possible associations to child disease severity and nutrition support mode. Methods A cross-sectional observational study was performed in 58 caregi…

Hip pain in adolescents: Results of a cross-sectional study in German pupils and a review of the literature

2007

Aim: To determine the prevalence of hip pain (HP) in adolescents in East Germany and to evaluate the potential factors associated with HP. Design: Cross-sectional epidemiological study of a total of 2368 pupils (1137 males, 1231 females; age 14.5±0.65, range 13–18 y). Demographic data and information on sports activity and consumption of soft legal drugs were obtained using a questionnaire. Physical examination was carried out by school doctors. Odds ratio (OR [95% confidence interval]) was calculated for common factors associated with HP. Results: The prevalence of adolescents suffering from HP was 6.5% (n=151). Pain episodes were reported as occasional in 3.0%. A total of 69 subjects (2.9…

Assessment of bioelectrical activity of pelvic floor muscles depending on the orientation of the pelvis in menopausal women with symptoms of stress u…

2017

Background Menopausal women often experience the prolapse of the uterus, bladder and rectum resulting from the failure and weakening of the pelvic floor muscles (PFM). Strengthening of the PFM through the standard exercises is recognized as an effective way of preventive measures and conservative treatment of the symptoms listed above, but still need to be improved. Aim The goal was the objective assessment of resting and functional bioelectrical activity of PFM in women during menopause and its comparison in three different positions of the pelvis: anterior pelvic tilt - position 1 (P1), posterior pelvic tilt - position 2 (P2), and neutral pelvic tilt - position 3 (P3). Design Prospective,…

Adaptation and Psychometric Properties of the Scale of Positive and Negative Experience (SPANE) in the General Colombian Population

2021

(1) Background: Diener’s Scale of Positive and Negative Experiences (SPANE) assesses the presence and intensity of positive and negative affects, since these are considered basic aspects of the study of well-being. This article studies its psychometric properties in the general Colombian population. (2) We conducted a cross-sectional study of a sample of 1255 Colombians and we used structural equation modeling to confirm the bifactor structure. Additionally, we studied invariance by gender, and convergent and concurrent validity. (3) We found acceptable fit indicators for the bifactor model (CFI = 0.889, RMSEA = 0.046, SRMR = 0.059) as well as for the convergent (CFI = 0.909, RMSEA = 0.050,…

Socio-behavioral factors, oral hygiene level and periodontitis prevalence in a 35-44-year-old Greek adult population: A cross-sectional survey

2021

Background Sub-optimal oral hygiene is considered as a primary risk factor for periodontitis occurrence. Various socio-behavioral determinants may contribute either independently or by influencing adversely the oral hygiene (OH) level. The aim of the present study was to examine the periodontal status of 35-44-year-old Greek adults and determine the contribution of risk indicators, including the socio-behavioral aspects and the population's oral hygiene level, on disease prevalence. Material and methods In 1218 participants, Community Periodontal Index (CPI), Loss of Attachment (LoA) and simplified Oral Hygiene Index (OHI-S) were calculated. Multivariable regression models examined the effe…

Illness perception, mood and coping strategies in allergic rhinitis: are there differences among ARIA classes of severity?

2014

Background: This study was designed to assess if illness perception, mood state and coping strategies differ according to allergic rhinitis (AR) persistence and severity. Methods: Illness perception, mood profiles, coping behaviors and rhinitis symptoms were assessed by means of validated tools inpatients classified according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) guidelines. Results: Two hundred and thirty-one patients underwent data analysis. No difference in age, sex, socio-economic status, smoking habits was detected comparing patients according to AR severity, duration or 4 ARIA classes. Patients with intermittent AR reported higher scores than those with persistent A…

Knowledge of and attitudes to influenza in unvaccinated primary care physicians and nurses

2014

Primary healthcare workers, especially nurses, are exposed to the vast majority of patients with influenza and play an important role in vaccinating patients. Healthcare workers' misconceptions about influenza and influenza vaccination have been reported as possible factors associated with lack of vaccination. The objective of this study was to compare the characteristics of unvaccinated physicians and unvaccinated nurses in the 2011-2012 influenza season. We performed an anonymous web survey of Spanish primary healthcare workers in 2012. Information was collected on vaccination and knowledge of and attitudes to the influenza vaccine. Multivariate analysis was performed using unconditional …

Antiepileptic drug use in nursing home residents: a cross-sectional, regional study.

2006

Summary The use of antiepileptic drugs (AED), their primary indication, comorbid conditions, and concomitant medications were collected from 565 nursing homes (NH) residents of six NH located around the city of Mainz, Germany representing 5.05% of all NH residents in the area. Data were collected from the electronic pharmacy files and by reviewing all available medical records. Average age was 82.2±2.4 years, 85.5% were women. Of 565 NH residents 28 (4.96%) received AED therapy, of which in 17 (63%) AED were prescribed for a seizure-related diagnosis. In 76.5% seizure types were unspecified and a distinction in focal and generalized epilepsy was made in only 23.5% of patients. Three patient…

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at √s = 7 TeV with the ATLAS detector

2011

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton–proton collisions at a centre-of-mass energy of √s =7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb[superscript −1]. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the ra…
