INTRODUCTION: We investigated the link between habitual caffeine intake with memory impairments and cerebrospinal fluid (CSF) biomarkers in mild cognitive impairment (MCI) and Alzheimer's disease (AD) patients. METHODS: MCI (N = 147) and AD (N = 116) patients of the Biomarker of AmyLoid pepTide and AlZheimer's diseAse Risk (BALTAZAR) cohort reported their caffeine intake at inclusion using a dedicated survey. Associations of caffeine consumption with memory impairments and CSF biomarkers (tau, p‐tau181, amyloid beta 1‐42 [Aβ1‐42], Aβ1‐40) were analyzed using logistic and analysis of covariance models. RESULTS: Adjusted on Apolipoprotein E (APOE ε4), age, sex, education level, and tobacco, lower caffeine consumption was associated with higher risk to be amnestic (OR: 2.49 [95% CI: 1.13 to 5.46]; p = 0.023) and lower CSF Aβ1‐42 (p = 0.047), Aβ1‐42/Aβ1‐40 (p = 0.040), and Aβ1‐42/p‐tau181 (p = 0.020) in the whole cohort. DISCUSSION: Data support the beneficial effect of caffeine consumption to memory impairments and CSF amyloid markers in MCI and AD patients. Highlights: We studied the impact of caffeine consumption in the BALTAZAR cohort.Low caffeine intake is associated with higher risk of being amnestic in MCI/AD patients.Caffeine intake is associated with CSF biomarkers in AD patients.

This research letter published in the Clinical & Experimental Allergy journal discusses a study on the effects of pulmonary rehabilitation (PR) on individuals with severe asthma. The study found that PR was associated with improvements in asthma control, a reduction in severe exacerbations, and a decrease in glucocorticoid use. However, the study had limitations and further research is needed to confirm these findings. Overall, the study suggests that PR may be beneficial for individuals with severe asthma, but more research is necessary to determine its role in managing the condition. [Extracted from the article]

Objectives The efficacy of anti-IL-6 receptors such as tocilizumab (TCZ) was demonstrated in patients with PMR in two recent randomized controlled trials. The objective of this multicentre retrospective study was to assess the efficacy of TCZ in PMR patients requiring glucocorticoid (GC)-sparing treatment, as well as different strategies for TCZ withdrawal. Methods We conducted a multicentre study in French tertiary healthcare departments for patients with PMR. PMR patients receiving off-label TCZ between 2015 and 2022 were included. The primary endpoint was the proportion of patients tapering to GCs ≤5 mg/day 6 months after the first TCZ infusion. The secondary endpoints were the proportion in whom GC was discontinued during follow-up, and the proportion of patients in whom TCZ was discontinued. Results Fifty-three PMR patients were included. Thirty-one patients suffered from active PMR despite conventional synthetic DMARDs. GCs were ≤5 mg/day in 77% of the patients (95% CI 36–89) at 6 months, and in 97% of the patients at 12 months. Six and 12 months after the first TCZ infusion, the proportions of GC-free patients were 22.5% (95% CI 12.7–37.8) and 58.3% (95% CI 43.2–74.1), respectively. Among TCZ withdrawal strategies, TCZ infusion spacing and TCZ dose reduction were more successful (success in 87% and 79% of attempts, respectively) than TCZ discontinuation (success in 52% of attempts; P  = 0.012 and P  = 0.039, respectively). Conclusion In GC-dependent PMR patients, treatment with TCZ led to a drastic decrease in GC dose and remission of PMR. TCZ dose reduction or TCZ infusion spacing are good options to consider in TCZ withdrawal. [ABSTRACT FROM AUTHOR]

Nonoperative management of severe caustic injuries has demonstrated its feasibility, avoiding the need for emergency esogastric resection and resulting in low mortality rates. However, leaving superficial necrosis in place could increase the risk of esophageal stricture development. Data on the risk factors of esophageal stricture secondary to caustic ingestion are scarce. The aim of our study was to identify the risk factors for esophageal strictures after caustic ingestion at admission. From February 2015 to March 2021, all consecutive patients with esophageal or gastric caustic injury score ≥ II according to the Zargar classification were retrospectively analyzed. For each patient, we collected over 50 criteria at admission to the emergency room and then selected among them 20 criteria with the best clinical relevance and limited missing data for risk factor analyses. Among the 184 patients included in this study, 37 developed esophageal strictures (cumulative rate 29.4%). All esophageal strictures occurred within 3 months. In multivariate analyses, the risk factors for esophageal strictures were voluntary ingestion (cause-specific hazard ratio 5.92; 95% confidence interval 1.76–19.95, P  = 0.004), Zargar's esophageal score ≥ III (cause-specific hazard ratio 14.30; 95% confidence interval 6.07–33.67, P  < 0.001), and severe ear, nose, and throat lesions (cause-specific hazard ratio 2.15; 95% confidence interval 1.09–4.22, P  = 0.027). Intentional ingestion, severe endoscopic grade, and severe ENT lesions were identified as risk factors for esophageal stricture following caustic ingestion. Preventive measures for this population require further evaluation. [ABSTRACT FROM AUTHOR]

Background: Baricitinib (BARI) or Tofacitinib (TOFA) were the first Janus Kinase Inhibitors (JAKi) to be marketed in rheumatoid arthritis (RA). Concerns regarding venous thromboembolism (VTE) risk have emerged during the past years. The aim of the study was to compare the baseline characteristics of patients initiating BARI or TOFA in RA before versus after European Medicine Agency (EMA)'s VTE warnings and to compare real-world persistence with these two drugs. Methods: In this multicentric cohort study, RA patients initiating BARI or TOFA were included from October 2017, date of BARI marketing authorization in France, to September 2020. Baseline characteristics regarding VTE risk were compared (before vs. after May 2019) by using pre-specified statistical tests. Comparison of persistence was assessed by using propensity-score methods. Results: 232 patients were included; 155 with BARI and 77 with TOFA. Baseline characteristics of patients regarding VTE risk factors were not statistically different when Janus Kinase inhibitor (JAKi) was initiated before vs. after EMA's warnings although a trend towards a lower proportion of VTE history was observed. Five VTE events occurred, four with BARI, one with TOFA. Cumulative persistence rate at 2 years was similar between BARI and TOFA: HR 0.96; 95% Cl: 0.52 to 1.74; p = 0.89. Conclusions: Our study did not show a significant change in patients characteristics starting a JAKi after the EMA's warnings, probably due to a lack of power. Though, the lower proportion of VTE history in patients after May 2019 suggests that rheumatologists have taken into account the potential VTE risk. These results need to be confirmed by further evidence. [ABSTRACT FROM AUTHOR]

The article discusses the results of a study on the influence of positive end-expiratory pressure (PEEP) on COVID-19 positive patients. Topics mentioned include the use of pulmonary artery catheter to determine the intrapulmonary shunt ratio and recruitment-to-inflation ratio for the evaluation of lung recruitment potential, the advanced physiologic variables at two levels of PEEP, the standard of medical care given to patients, and the determination of airway closure and opening pressure.

Previous studies have identified cirrhosis as a risk factor for ventilator-associated pneumonia (VAP). The aim of our study was to determine the relationship between cirrhosis and abundant gastric-content microaspiration in intubated critically ill patients. We performed a matched cohort study using data from three randomized controlled trials on abundant microaspiration in patients under mechanical ventilation. Each cirrhotic patient was matched with three to four controls for gender, age ± 5 years and simplified acute physiology score II (SAPS II) ± 5 points. Abundant microaspiration was defined by significant levels of pepsin and alpha-amylase in >30% of tracheal aspirates. All tracheal aspirates were collected for the first 48 h of the study period. The percentage of patients with abundant gastric-content microaspiration was the primary outcome. The abundant microaspiration of oropharyngeal secretions, VAP incidence, the duration of mechanical ventilation, length of intensive care unit (ICU) stay and mortality were the secondary outcomes. A. total of 39 cirrhotic patients were matched to 138 controls. The percentage of patients with abundant gastric-content microaspiration did not differ between the two groups (relative risk: 0.91 (95% CI: 0.75 to 1.10)). There was no significant difference between the two groups in terms of the abundant microaspiration of oropharyngeal secretions, VAP, the duration of mechanical ventilation, the length of ICU stay and mortality. Our results suggest that cirrhosis is not associated with abundant gastric-content microaspiration. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to determine the association between different histological patterns and prognosis in patients with SSc and histologically proven muscle involvement., Methods: A multicentre retrospective study was conducted of a cohort of scleroderma patients who had undergone muscle biopsy. The biopsies were reviewed in a coordinated manner to classify patients based on histological findings. Three different patterns were observed: fibrosing myopathy (FM), inflammatory myopathy (IM) and necrotizing myopathy (NM). Rates of survival, muscle relapse, and cardiac and pulmonary events were compared between these three groups., Results: Among 71 scleroderma patients with muscle biopsy specimens available for review, 33 (46.5%) were classified in the FM group, 18 (25.5%) in the IM group, and 20 (28%) in the NM group. The median follow-up time was 6.4 years (interquartile range, 2.2-10.9 years) and 21 patients died during follow-up, primarily from heart disease and infections. The 10-year survival rate after the first non-Raynaud's disease symptom was 80% and the cumulative incidence of muscle relapse was 25%. Neither factor differed significantly between the three groups. The risk of pulmonary events was lowest in the OM group, significantly lower than in the FM group (hazard ratio, 0.17; 95% CI, 0.04-0.67) and non-significantly lower than in the IMNM group (hazard ratio, 0.28; 95% CI, 0.06-1.24). The risk of cardiac events did not differ significantly between the three groups., Conclusion: The mortality rate of scleroderma patients with muscle involvement was not associated with their histological patterns., (© The Author(s) 2024.

Objective: In comparison to eutrophic fetuses, intra uterine growth restriction fetuses (IUGR) have a higher risk of perinatal morbi-mortality. There are no guidelines on the labor induction of labor (IOL) method to be performed in IUGR. The main objective was to determine fetal and maternal predictive factors of successful induction in IUGR fetuses from 36 weeks. Study design We conducted a retrospective cohort single-center study including 320 women with a cephalic fetal presentation. Labour was induced after 36 weeks for suspected IUGR between January 2013 and December 2019., Results: Among the 320 patients, 246 were delivered vaginally (76.9 %) and 74 had a cesarean (23.1 %). Prognostic factors for successful IUGR induction were nonscarring uterus (OR 8.41; 95 %CI [2.92-24.21]), absence of preeclampsia (OR 7.14; 95 %CI [2.42-21.03]), multiparity (OR 4.32; 95 %CI [1.83-10.18]), normal fetal heart rate before IOL (OR 2.99; 95 %CI [1.24-7.22]) and BMI < 30 (OR 3.54; 95 %CI [1.62-7.72]). Doppler abnormalities, method and number of line of IOL, cervical evaluation were not significant in our study., Conclusion: The prognostic factors for successful IUGR induction are essentially maternal. Thus, a low BMI, multiparity, nonscarring uterus, absence of preeclampsia, and a normal FHR are good prognostic factors in IUGR induction., (Copyright © 2022 Elsevier B.V. All rights reserved.)
