Comparison of clinical characteristics between coronavirus disease 2019 pneumonia and community-acquired pneumonia
2020
Coronavirus disease 2019 (COVID-19) has high morbidity and mortality, and spreads rapidly in the community to result in a large number of infection cases. This study aimed to compare clinical features in adult patients with coronavirus disease 2019 (COVID-19) pneumonia to those in adult patients with community-acquired pneumonia (CAP).Clinical presentations, laboratory findings, imaging features, complications, treatment and outcomes were compared between patients with COVID-19 pneumonia and patients with CAP. The study group of patients with COVID-19 pneumonia consisted of 120 patients. One hundred and thirty-four patients with CAP were enrolled for comparison.Patients with COVID-19 pneumo…
Myopia and Cognitive Performance: Results From the Gutenberg Health Study.
2016
Purpose To analyze the association between myopia and cognitive performance. Methods A cohort of the population-based Gutenberg Health Study included 3819 eligible enrollees between 40 and 79 years. We used the Tower of London (TOL) test to assess cognitive performance. Myopia was defined as a spherical equivalent (SE) ≤ -0.5 diopters (D) via noncycloplegic autorefractometry. We conducted linear mixed models with the SE as the dependent variable and the age, sex, duration of education, and TOL score as covariates. Results Complete data were available for 3452 participants (90.4%). The mean TOL score was 14.0 ± 3.9 in the myopes versus 12.9 ± 4.0 in the nonmyopes (P < 0.001). The mean TOL sc…
Accuracy between virtual surgical planning and actual outcomes in orthognathic surgery by iterative closest point algorithm and color maps: A retrosp…
2018
Background To evaluate the accuracy between actual outcomes and virtual surgical planning (VSP) in orthognathic surgery regarding the use of three-dimensional (3D) surface models for registration using iterative closest point (ICP) algorithm and generated color maps. Material and Methods Construction of planning and postoperative 3D models in STL files format (M0 and M1, respectively) from CBCT of 25 subjects who had been submitted to bimaxillary orthognathic surgery was performed. M0 and M1 were sent to Geomagic software in semi-automatic alignment surface mesh order of M0 and M1 for registration using ICP algorithm to calculate mean deviation (MD, MD+, MD-, SD) and root mean square (RMS –…
Impact of pharmaceutical intervention on quality of life and coping strategies in patients with haematological malignancies
2015
Summary Objectives We conducted a prospective study approved by the local ethics committee to determine the impact of a pharmaceutical intervention (PI) on pain, fatigue, quality of life (QoL) and coping strategies in patients with HMs starting chemotherapy sessions. Material and methods Patients received either usual care (UC) + PI (PI group) or UC alone (UC group). They had to complete 2 questionnaires, QLQ-C30 and MAC 21, at 3 different time points: before starting the 1st chemotherapy session (T1), during the intercure (T2) and the day before starting the 2nd chemotherapy session (T3). To determine predictive factors of pain, fatigue, QoL and coping scores at T3, a multivariate ANOVA wa…
Association between dietary and beverage consumption patterns in the SUN (Seguimiento Universidad de Navarra) cohort study.
2008
Objective: The objective of the present study was to determine the dietary patterns of a Mediterranean cohort and relate them to the observed patterns of beverage consumption. Design: Prospective cohort study. Dietary habits were assessed with a semiquantitative FFQ validated in Spain. A principal components factor analysis was used to identify dietary patterns and to classify subjects according to their adherence to these patterns. The association between adherence to each dietary pattern and beverage consumption was assessed cross-sectionally. In a longitudinal analysis (2-year follow-up), the relationship between adherence to the baseline dietary patterns and the likelihood of changing a…
Visceral infiltration of intrahepatic cholangiocarcinoma is most prognostic after curative resection - Retrospective cohort study of 102 consecutive …
2018
Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy, and therefore large unicenter series on the surgical outcome are rare in the literature, and prognostic factors for overall survival in the literature vary widely.All patients who underwent surgery for ICC were prospectively recorded. The type of resection, operative details, histological results, morbidity, mortality, overall and recurrence-free survivals as well as prognostic factors were assessed. Prognostic factors were examined by univariate and multivariate analyses. P-values0.05 were considered significant.Between January 2008 and December 2015, 102 patients underwent a resection with curative intent and were included in thi…
Outcomes after acute myocardial infarction in HIV-infected patients: analysis of data from a French nationwide hospital medical information database.
2013
Background— We aimed to assess in-hospital case fatality and 1-year prognosis in HIV-infected patients with acute myocardial infarction. Methods and Results— From the PMSI (Program de Medicalisation des Systèmes d’informatique) database, data from 277 303 consecutive acute myocardial infarction patients hospitalized from January 1, 2005, to December 31, 2009, were analyzed. Surviving patients were followed up for 1 year after discharge. HIV-infected patients were compared with uninfected patients. Among the cohort, HIV-infected patients (n=608) accounted for 0.22%. All-cause hospital and 1-year mortality rates were lower in the HIV-infected group than in uninfected patients (3.1% versus 8.…
Tooth loss in Sjögren’s syndrome patients compared to age and gender matched controls
2018
Background To analyze the prevalence and location of tooth loss in Sjögren’s syndrome (SS) patients and compare them with an age- and gender-matched control group. Material and Methods Dental charts and x-rays of 108 (SS) patients were retrieved from an academic dental center and special care dentistry department. For each SS patient, an age- and gender-matched non-SS patient was randomly selected. Medication, number of extractions and date and location of extractions were assessed. Differences between SS and non-SS patients were analyzed using Mann-Whitney U tests, Chi-square tests and Fisher’s exact tests. Results Significantly more SS patients were edentulous compared to the non-SS group…
Clinical evaluation of drug-induced hepatitis
2005
Objective: to ascertain the epidemiological characteristics, clinical symptoms, and evolution of drug-induced hepatitis over the last 22 years. Experimental design and subjects: an observational, retrospective study between 1982 and 1993, and prospective study between 1994 and 2003. All patients in our department diagnosed with having drug-induced hepatitis were studied analyzing epidemiological (age, sex, cases per year, hospitalization) and clinical features (previous liver disease, hepatic symptoms, laboratory results), and follow-up (complete recovery or chronicity). Results: a total of 61 patients were diagnosed as having drug-induced hepatitis, 26 men and 35 women (57%), mean age 52.4…
Improved drug-use patterns at 6 months post-discharge from inpatient substance use disorder treatment: Results from compulsorily and voluntarily admi…
2016
Background Treatment services to patients with substance use disorders (SUDs), including those mandated to treatment, needs to be evaluated and evidence based. The Norwegian Municipal Health Care Act calls for mandated treatment for persons with “severe and life-threatening substance use disorder” if these individuals are not otherwise willing to be voluntarily treated and consequently risk their lives over drug use. This study aims to examine substance use–related outcomes at 6 months following inpatient treatment and to analyse factors associated with improved outcomes and abstinence. Method This prospective study followed 202 hospitalized patients with SUD who were admitted voluntarily (…
