Alternatives to Endotracheal Intubation for Patients with Neuromuscular Diseases
2005
To evaluate the usefulness of continuous noninvasive mechanical ventilation and mechanical coughing aids to avoid endotracheal intubation and tracheostomy during episodes of acute respiratory failure in patients with neuromuscular disease.We conducted a prospective cohort study at the respiratory medicine ward of a university hospital to study the success rate of the use of continuous noninvasive mechanical ventilation and manually and mechanically (CoughAssist) assisted coughing to avert endotracheal intubation in 24 consecutive episodes of acute respiratory failure for 17 patients with neuromuscular disease. The noninvasive mechanical ventilation and coughing aids were used to reverse dec…
Ranibizumab for Branch Retinal Vein Occlusion Associated Macular Edema Study (RABAMES): six-month results of a prospective randomized clinical trial
2014
Purpose To compare standard-of-care grid laser photocoagulation versus intravitreal ranibizumab (IVR) versus a combination of both in the treatment of chronic (>3 months) macular oedema secondary to branch retinal vein occlusion. Methods Prospective, randomized, multicentre clinical trial. Thirty patients with a best-corrected visual acuity (BCVA) between 20/320 and 20/40 were randomized 1:1:1 to receive grid laser or three monthly injections of 0.5 mg IVR or both followed by 3 months of observation. Results Mean change from baseline BCVA at month 6 was +2 letters [laser; 0.04 logMAR, 95% confidence interval (−0.17; 0.25)], +17 letters [IVR; 0.34 (0.19; 0.5)] and +6 letters [combination; 0.…
Chocolate Consumption and Indicators of Adiposity in US Adults.
2020
International audience; Purpose: The purpose of this research is to investigate the association between consumption of chocolate and measures of adiposity in a large, representative sample of US adults. Methods: Cross-sectional data from 13,626 nondiabetic adults (≥20 years) participating in the National Health and Nutrition Examination Survey study were aggregated using 5 study cycles from 2005-2006 through 2013-2014. Chocolate consumption was determined based on 2 24-hour dietary recalls. Body mass index (BMI) and waist circumference were objectively measured. We used multivariable linear regression to test associations of 1) any chocolate consumption (yes/no), and 2) the total amount of …
Maxillofacial trauma due to traffic accidents and falls: an exploratory study of associated factors
2020
Background This study aimed to determine the pattern of Maxillofacial trauma (MFT) due to traffic accidents and falls in a reference hospital in a rural region of northeastern Brazil between December 2011 and December 2018 and to identify associated factors. Material and Methods This was a cross-sectional study using 585 medical records of patients with MFT. The data were subjected to a Poisson-Tweedie multiple regression analysis to estimate the Prevalence ratio (PR), with a 95% confidence interval (95% CI) and a significance level of p<0.05. Results MFT due to traffic accidents was more prevalent among patients 21 to 40 years old (PR=2.30; 95% CI=1.20-4.41; p<0.001) diagnosed with zygomat…
Metabolic syndrome and body weight in people living with HIV infection: analysis of differences observed in three different cohort studies over a dec…
2022
Objectives: The aim of this study was to assess the incidence of being overweight and metabolic syndrome (MS) among people living with HIV (PHIV) in three different cross-sectional studies conducted over three different periods: 2005, 2011 and 2015. Methods: This was a multi-centre, nationwide study. Data were collected in three studies from the CISAI group - SIMOne, HIV-HY and STOPSHIV - and included a total of 3014 PHIV. Logistic regression [odds ratio (OR), 95% confidence interval (CI)] was used to account for age and gender difference among three groups when comparing MS prevalence and being overweight; potential confounders were accounted for by including them in the regression equatio…
DNA single strand break analysis in mononuclear blood cells of petrol pump attendants
1995
DNA single strand breaks, including DNA adducts that lead to alkali-labile sites, were measured in peripheral mononuclear blood cells of 35 petrol pump attendants by alkaline filter elution. Blood samples from petrol pump attendants were taken on Monday and Friday. Additionally, DNA single strand breaks of smoking and non-smoking control persons were examined. For the smoking (n = 12) and the non-smoking controls (n = 20) a mean normalized elution rate of 1.49 +/- 0.52 (mean value +/- 95% confidence interval) and 1.32 +/- 0.28, respectively, was obtained. The difference between smoking and non-smoking controls was not statistically significant (U test). An increase in DNA single strand brea…
Objective analysis of contact lens fit.
2015
Purpose: To assess the validity and repeatability of objective compared to subjective contact lens fit analysis. Methods: Thirty-five subjects (aged 22.0. ±. 3.0 years) wore two different soft contact lens designs. Four lens fit variables: centration, horizontal lag, post-blink movement in up-gaze and push-up recovery speed were assessed subjectively (four observers) and objectively from slit-lamp biomicroscopy captured images and video. The analysis was repeated a week later. Results: The average of the four experienced observers was compared to objective measures, but centration, movement on blink, lag and push-up recovery speed all varied significantly between them (p 0.05). The 95% conf…
Associations between cataract and multimorbidity: a cross-sectional study of 23,089 adults from Spain
2020
Background: Little is known about the association between cataract and multimorbidity. Therefore, the aim of the present study was to examine the relationship between cataract and chronic conditions and multimorbidity in a large representative sample of Spanish adults. Methods: This study used data from the Spanish National Health Survey 2017, a cross-sectional sample of 23,089 adults aged ≥15 years from Spain [54.1% female; mean (standard deviation) age 53.4 (18.9) years]. Cataract and 30 other physical and mental chronic conditions were self-reported. Multimorbidity was defined as the presence of at least two physical and/or mental chronic conditions (excluding cataract). Control variable…
BMI and an anthropometry-based estimate of fat mass percentage are both valid discriminators of cardiometabolic risk: A comparison with DXA and bioim…
2013
Objective. To determine whether categories of obesity based on BMI and an anthropometry-based estimate of fat mass percentage (FM% equation) have similar discriminative ability for markers of cardiometabolic risk as measurements of FM% by dual-energy X-ray absorptiometry (DXA) or bioimpedance analysis (BIA).Design and Methods. A study of 40–79-year-old male (n=205) and female (n=388) Finns. Weight, height, blood pressure, triacylglycerols, HDL cholesterol, and fasting blood glucose were measured. Body composition was assessed by DXA and BIA and a FM%-equation.Results. For grade 1 hypertension, dyslipidaemia, and impaired fasting glucose >6.1 mmol/L, the categories of obesity as defined b…
Diseño de una nueva prueba para medir la función de sensibilidad al contraste con iPad
2015
[EN] Purpose: To introduce a new application (ClinicCSF) to measure Contrast Sensitivity Function (CSF) with tablet devices, and to compare it against the Functional Acuity Contrast Test (FACT). Methods: A total of 42 subjects were arranged in two groups of 21 individuals. Different versions of the ClinicCSF (.v1 and .v2) were used to measure the CSF of each group with the same iPad and the results were compared with those measured with the FACT. The agreements between ClinicCSF and FACT for spatial frequencies of 3, 6, 12 and 18 cycles per degree (cpd) were represented by Bland---Altman plots. Results: Statistically significant differences in CSF of both groups were found due to the change…
