Access to and characteristics of palliative care-related hospitalization in the management of end-stage renal disease patients on renal replacement therapy in France

International audienceAIM:Palliative care is seldom proposed to patients with end-stage renal disease (ESRD) despite a mortality rate and disease burden as high as among cancer patients. The aim of this study is to analyze the access of palliative care-related hospitalization in the management of patients on dialysis in France, by describing the characteristics of these hospitalizations, the clinical status of the concerned patients, and the use of palliative care in those stopping dialysis.METHODS:The French Renal Epidemiology and Information Network (REIN) registry includes data about 51 834 patients aged 20 years and older who began dialysis from 1 January 2008 to 31 December 2013, and were followed longitudinally until that date. Linkage to the anonymized national hospital discharge database allowed us to analyse hospitalizations associated with palliative care.RESULTS:During the follow-up period, 1865 patients (3.6%) had a palliative care-related hospitalization corresponding to a total of 3382 hospitalizations. Lower levels of serum albumin, active cancer, and impaired mobility were each independently associated with the probability of at least one such hospitalization. During the same period 4540 patients withdrew from dialysis (9% of the patients), 10% of them had a palliative care-related hospitalization.CONCLUSION:This study suggests that among ESRD patients, only a few resorted to palliative care-related hospitalization, even those withdrawing from dialysis. Cooperation between nephrologists and physicians trained in palliative care should be improved at least to the extent necessary to identify patients who should be referred to palliative care. Our study also highlights the need for more information on the current access to any kind of supportive care for dialysis patients

Effects of Inhaled Fenoterol and Positive End-Expiratory Pressure on the Respiratory Mechanics of Patients with Chronic Obstructive Pulmonary Disease

BACKGROUND: During acute ventilatory failure in patients with chronic obstructive pulmonary disease (COPD), applying external positive end-expiratory pressure (PEEPe) will reopen small airways and, thus, may enhance peripheral deposition as well as the physiological effects of inhaled beta-2 agonists

Deposition of aerosols delivered by nasal route with jet and mesh nebulizers

PURPOSE: To quantify the amount of aerosol deposited in different parts of the airways with a commercially available nasal sonic jet nebulizer (NJN) using a sound effect, and to compare its performance with a new nasal mesh nebulizer (NMN). METHODS: Seven healthy non-smoking male volunteers aged 21-36 years with a mean weight of 77±10 kg were included in this single-center study. Both nebulizer systems were loaded with (99m)Tc-DTPA and scintigraphies were performed with a gamma camera. Particle size distribution of the aerosols produced by the two nebulizer systems was measured. RESULTS: There was no statistical difference between the two nebulizers in terms of fraction of particles smaller than 5 μm (44±4% vs 45±2%) (p>0.9). Aerosol deposition in the nasal region was 73±10% (% of aerosol deposited in airways) with the NJN, and 99±3% with the NMN (p=0.01). Total nasal deposition was 9.6±1.9% of the nebulizer charge with the NJN and 28.4±8.9% with the NMN (p=0.01). 0.5±0.3% of the nebulizer charge was deposited in the maxillary sinuses with the NJN, compared to 2.2±1.6% with the NMN (p=0.01). CONCLUSION: Although the two nebulizers had the same particle size, NMN significantly improved aerosol deposition in nasal cavity and prevents deposition into the lungs

Evaluation of the VISAGE basic tool for appearance and ancestry inference using ForenSeq® chemistry on the MiSeq FGx® system

The possibility of providing investigative leads when conventional DNA identification methods fail to solve a case can be of extreme relevance to law enforcement. Therefore, the forensic genetics community has focused research towards the broadened use of DNA, particularly for prediction of appearance traits, bio-geographical ancestry and age. The VISible Attributes through GEnomics (VISAGE) Consortium expanded the use of DNA phenotyping by developing new molecular and statistical tools for appearance, age and ancestry prediction. The VISAGE basic tool for appearance (EVC) and ancestry (BGA) prediction was initially developed using Ampliseq chemistry, but here is being evaluated using ForenSeq chemistry. The VISAGE basic tool offers a total of 41 EVC and 115 BGA SNPs and thus provides more predictions, i.e., skin color, than achieved with the ForenSeq DNA Signature Prep kit that is based on 24 EVC and 56 BGA SNPs. Five VISAGE laboratories participated in collaborative experiments to provide foreground for developmental validation of the assay. Assessment of assay performance and quality metrics, reproducibility, sensitivity, inhibitor tolerance and species specificity are described. Furthermore, the assay was tested using challenging samples such as mock casework samples and artificially degraded DNA. Two different analysis strategies were applied for this study and output on genotype calls and read depth was compared. Overall, inter-laboratory, inter-method and concordance with publicly available data were analysed and compared. Finally, the results showed a reliable and robust tool, which can be easily applied for laboratories already using a MiSeq FGx with ForenSeq reagents
