Background There is limited information describing the characteristics and outcomes of hospitalized older patients with confirmed coronavirus disease 2019 (COVID-19). Methods We conducted a multicentric retrospective cohort study in 13 acute COVID-19 geriatric wards, from March 13 to April 15, 2020, in Paris area. All consecutive patients aged ≥ 70 years, with confirmed COVID-19, were enrolled. Results Of the 821 patients included in the study, the mean (SD) age was 86 (7) years; 58% were female; 85% had ≥ 2 comorbidities; 29% lived in an institution; and the median (interquartile range) Activities of Daily Living Scale (ADL) score was 4 [2-6]. The most common symptoms at COVID-19 onset were asthenia (63%), fever (55%), dyspnea (45%), dry cough (45%) and delirium (25%). The in-hospital mortality was 31% (95% confidence interval [CI], 27 to 33). On multivariate analysis, at COVID-19 onset, the probability of in-hospital mortality was increased with male gender (odds ratio [OR], 1.85; 95% CI, 1.30 to 2.63), ADL score < 4 (OR, 1.84; 95% CI, 1.25 to 2.70), asthenia (OR, 1.59; 95% CI, 1.08 to 2.32), quick Sequential Organ Failure Assessment score ≥ 2 (OR, 2.63; 95% CI, 1.64 to 4.22) and specific COVID-19 anomalies on chest computerized tomography (OR, 2.60; 95% CI, 1.07 to 6.46). Conclusions This study provides new information about older patients with COVID-19 who are hospitalized. A quick bedside evaluation at admission of sex, functional status, systolic arterial pressure, consciousness, respiratory rate and asthenia can identify older patients at risk of unfavorable outcomes.
Background: ω-5 gliadin is a major allergen in exercise-induced wheat allergy (EIWA), but it is also implicated in immediate-type reactions to wheat. An ImmunoCAP assay to measure ω-5 gliadin-specific IgE has become available. This study aimed to evaluate this new biological test in wheat allergy diagnosis and to also determine if it was able to discriminate EIWA from other types of wheat allergy. Methods: Sixty-one patients with wheat allergy were divided into 3 groups as a function of their symptoms (EIWA, immediate-type reactions and atopic dermatitis). These patients underwent skin prick tests with purified ω gliadins and ImmunoCAP to wheat flour, gluten and recombinant ω-5 gliadin. Results: The experimental data showed that 78% of EIWA patients had a positive skin prick test to natural ω-5 gliadin and the same proportion had detectable specific IgE to recombinant ω-5 gliadin, indicating that ω-5 gliadin is the main allergen, but not the only one, in our population. Additionally, we showed that this detection was not EIWA specific since ω-5 gliadin-specific IgE was detected in 30% of other patients who had a wheat allergy. These results lead to a positive predictive value of 37.5% and to a negative predictive value of 91%. Conclusions: Although not specific to EIWA, the new ImmunoCAP ω-5 gliadin is an important biological test because of its negative predictive value. In case of food-dependent exercise-induced allergy, the absence of ω-5 gliadin-specific IgE will almost completely exclude the implication of wheat.
Background Road safety is a major issue among seniors. Potentially Driver-Impairing (PDI) drugs are known to increase the risk of car accident. The aim of this cross-sectional study was to describe PDI-drug consumption among older drivers and determine associated factors. Methods The S.AGES cohort is a French non-interventional real-life prospective study of 3700 community-dwelling participants aged ≥65 years old, suffering from type 2 diabetes (T2DM), chronic pain or atrial fibrillation (AF). Baseline data of drivers with known treatment (n = 1783) were used for the analyses. PDI drugs were defined according to the French classification. Results One thousand seven hundred eighty-three drivers were included (66% males; mean age 76 (Standard deviation = 5.78) years old). 21% (n = 373) took PDI drugs, 64% of which took only one (n = 239). The most frequent PDI drugs were: Zolpidem (11%; n = 60); Zopiclone (8%; n = 45); Bromazepam (8%; n = 44); Tramadol (7%; n = 39); Pregabalin (6%; n = 31). Drivers taking PDI drugs had more often chronic pain (OR [95% CI] = 2.30 [1.54–3.46]), history of depressive disorder (4.28 [3.00–6.14]) and polypharmacy (taking at least 5 different medications; 4.32 [2.97–6.41]), and less often T2DM (0.54 [0.37–0.79]), and AF (0.48 [0.32–0.71]). Conversely, they had a lower Activities of Daily Living score (0.34 [0.17–0.68]). Conclusions The rate of aged drivers in the S.AGES cohort taking PDI drugs is concerning and highlights the need to carefully assess and reassess PDI-drug prescriptions in this population, particularly hypnotics, anxiolytics and opioids.
