RESUMO
BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disease that leads to progressive disability. Cost studies have mainly explored the early stages of the disease, whereas late-stage patients are underrepresented. OBJECTIVE: The aim is to evaluate the resource utilization and costs of PD management in people with late-stage disease. METHODS: The Care of Late-Stage Parkinsonism (CLaSP) study collected economic data from patients with late-stage PD and their caregivers in five European countries (France, Germany, the Netherlands, UK, Sweden) in a range of different settings. Patients were eligible to be included if they were in Hoehn and Yahr stage >3 in the on state or Schwab and England stage at 50% or less. In total, 592 patients met the inclusion criteria and provided information on their resource utilization. Costs were calculated from a societal perspective for a 3-month period. A least absolute shrinkage and selection operator approach was utilized to identify the most influential independent variables for explaining and predicting costs. RESULTS: During the 3-month period, the costs were 20,573 (France), 19,959 (Germany), 18,319 (the Netherlands), 25,649 (Sweden), and 12,156 (UK). The main contributors across sites were formal care, hospitalization, and informal care. Gender, age, duration of the disease, Unified Parkinson's Disease Rating Scale 2, the EQ-5D-3L, and the Schwab and England Scale were identified as predictors of costs. CONCLUSION: Costs in this cohort of individuals with late-stage PD were substantially higher compared to previously published data on individuals living in earlier stages of the disease. Resource utilization in the individual sites differed in part considerably among these three parameters mentioned. © 2024 The Authors.

OBJECTIVE: The Care of Late-Stage Parkinsonism (CLaSP) study aimed to collect qualitative and standardized patient data in six European countries (France, Germany, Netherlands, Portugal, UK, Sweden) to enable a detailed evaluation of the underexplored late stages of the disease (Hoehn and Yahr stage > 3) using clinical, neuropsychological, behavioral, and health economic data. The aim of this substudy was to provide a health economic evaluation for the German healthcare system. METHODS: In Germany, 228 patients were included in the study. Costs were calculated from a societal perspective for a 3-month period. Univariate analyses were performed to identify cost-driving predictors. Total and direct costs were analyzed using a generalized linear model with a γ-distributed dependent variable and log link function. Indirect costs were analyzed using a binomial generalized linear model with probit link function. RESULTS: The mean costs for the 3-month period were approximately 20,000. Informal care costs and hospitalization are approximately 11,000 and 5000. Direct costs amounted to 89% of the total costs, and the share of indirect costs was 11%. Independent predictors of total costs were the duration of the disease and age. The duration of the disease was the main independent predictor of direct costs, whereas age was an independent predictor of indirect costs. DISCUSSION: Costs in the late stage of the disease are considerably higher than those found in earlier stages. Compared to the latter, the mean number of days in hospital and the need for care is increasing. Informal caregivers provide most of the care. CLINICAL TRIAL REGISTRATION: The protocol was registered at ClinicalTrials.gov as NCT02333175 on 7 January, 2015.

Several recent reviews have suggested a role of oxidative stress in the pathophysiology of COVID-19, but its interplay with disease severity has not been revealed yet. In the present study, we aimed to investigate the association between the severity of COVID-19 and oxidative stress parameters. Clinical data of 77 patients with COVID-19 admitted to the hospital were analyzed and divided into moderate (n = 44) and severe (n = 33) groups based on their clinical condition. Production of oxidant (hydrogen peroxide) and defense antioxidants (total antioxidant capacity, reduced and oxidized glutathione, glutathione s-transferase), and oxidative damage (malondialdehyde, carbonyl, and sulfhydryl) were assessed using the serum samples. The results revealed that severe patients who presented high serum leukocyte count and CRP level stayed for a longer period in the hospital. However, there was no correlation observed between the oxidative stress parameters and degree of COVID-19 severity in the present study. In conclusion, these results indicate that the disease severity may not be a detrimental factor contributing to the changes in the redox profile of hospitalized patients with COVID-19.

BACKGROUND: Patients with sepsis-induced Acute Respiratory Distress Syndrome (ARDS) are hallmarked by high mortality rates. Early, targeted antibiotic therapy is crucial for patients' survival. The clinical use of a Next Generation Sequencing (NGS)-based approach for pathogen identification may lead to an improved diagnostic performance. Therefore, the objective of this study was to examine changes in the pulmonary-microbiome and resulting influences on patients' outcome in septic ARDS, but also to compare NGS- and culture-based diagnostic methods for pathogen identification. METHODS: In total, 30 patients in two groups were enrolled in the study: (1) 15 septic ARDS patients following major abdominal surgery and (2) 15 patients undergoing oesophageal resection serving as controls. In the ARDS group, blood samples were collected at ARDS onset as well as 5 days and 10 days afterwards. At the same timepoints, bronchoalveolar lavages (BAL) were performed to collect epithelial lining fluid for culture-, as well as NGS-based analyses and to evaluate longitudinal changes in the pulmonary microbiome. In the control group, only one BAL and one blood sample were collected. RESULTS: ARDS patients showed a significantly reduced α-diversity (p=0.007**) and an increased dominance (p=0.012*) in their pulmonary-microbiome. The α-diversity-index correlated with the length of stay in the intensive care unit (p-value=0.015) and the need for mechanical ventilation (p-value=0.009). In 42.9% of all ARDS patients, culture-based results were negative, while NGS findings indicated bacterial colonization. CONCLUSION: Sepsis-induced ARDS is associated with a significant dysbiosis of patients' pulmonary-microbiome, which is closely correlated with the clinical course of the disease. TRIAL REGISTRATION: This prospective, observational pilot study was approved by the Ethics Committee of the Medical Faculty of Heidelberg (trial code no. S-063/2015) and was prospectively registered in the German clinical trials register (DRKS-ID: DRKS00008317 prospectively registered: 28.10.2015). All study patients or their legal representatives signed written informed consent.
RESUMO
The analysis of volatiles from bacterial cultures revealed long-chain aliphatic nitriles, a new class of natural products. Such nitriles are produced by both Gram-positive Micromonospora echinospora and Gram-negative Pseudomonas veronii bacteria, although the structures differ. A variable sequence of chain elongation and dehydration in the fatty acid biosynthesis leads to either unbranched saturated or unsaturated nitriles with an ω-7 double bond, such as (Z)-11-octadecenenitrile, or methyl-branched unsaturated nitriles with the double bond located at C-3, such as (Z)-13-methyltetradec-3-enenitrile. The nitrile biosynthesis starts from fatty acids, which are converted into their amides and finally dehydrated. The structures and biosyntheses of the 19â naturally occurring compounds were elucidated by mass spectrometry, synthesis, and feeding experiments with deuterium-labeled precursors. Some of the nitriles showed antimicrobial activity, for example, against multiresistant Staphylococcus aureus strains.
