Precautions to Consider in the Analysis of Prognostic and Predictive Indices.

Understanding the differences between prognostic and predictive indices is imperative for medical research advances. We have developed a new prognostic measure that will identify the strengths, limitations, and potential applications in clinical practice.

Long-term psycho-traumatic consequences of the COVID-19 health crisis among emergency department healthcare workers.

Assess the changes in post-traumatic stress disorder (PTSD), burnout, anxiety, depression, jobstrain, and isostrain levels over time among healthcare workers in emergency departments (EDs) after successive outbreaks of COVID-19. A prospective, multicenter study was conducted in 3 EDs and an emergency medical service. Healthcare workers who participated in our previous study were invited to participate in a follow-up 16 and 18 months and completed the questionnaires to assess symptoms of PTSD, burnout, anxiety, depression, jobstrain, and isostrain.

Neurological outcomes in immune checkpoint inhibitor-related neurotoxicity.

While the spectrum of neurological immune checkpoint inhibitor-related adverse events is expanding, patients' outcomes are not well documented. This study aimed to assess outcomes of neurological immune-related adverse events and to identify prognostic factors. All patients experiencing grade ≥2 neurological immune-related adverse events identified at two clinical networks (French Reference Center for Paraneoplastic Neurological Syndromes, Lyon; and OncoNeuroTox, Paris) over five years were included.

Stronger Impact of COVID-19 in Nursing Homes of a French Region During the Second Pandemic Wave.

Objectives: Quantify the effects of characteristics of nursing homes and their surroundings on the spread of COVID-19 outbreaks and assess the changes in resident protection between the first 2 waves (March 1 to July 31 and August 1 to December 31, 2020).

Design: An observational study was carried out on data on COVID-19 outbreaks extracted from a database that monitored the spread of the virus in nursing homes.

Setting And Participants: The study concerned all 937 nursing homes with >10 beds in Auvergne-Rhône-Alpes region, France.

Effective dose of ephedrine for treatment of hypotension after induction of general anaesthesia in neonates and infants less than 6 months of age: a multicentre randomised, controlled, open label, dose escalation trial.

Background: The recommended dose of ephedrine in adults (0.1 mg kg) frequently fails to treat hypotension after induction of general anaesthesia in neonates and infants less than 6 months of age. The aim of this study was to determine the optimal dose of ephedrine in this population for the treatment of hypotension after induction of general anaesthesia with sevoflurane.

COVID-19 outbreaks in nursing homes: A strong link with the coronavirus spread in the surrounding population, France, March to July 2020.

Background: Worldwide, COVID-19 outbreaks in nursing homes have often been sudden and massive. The study investigated the role SARS-CoV-2 virus spread in nearby population plays in introducing the disease in nursing homes.

Material And Methods: This was carried out through modelling the occurrences of first cases in each of 943 nursing homes of Auvergne-Rhône-Alpes French Region over the first epidemic wave (March-July, 2020).

Coffee consumption and seizure frequency in patients with drug-resistant focal epilepsy.

Objective: To assess the relation between coffee consumption and seizure frequency in patients with drug-resistant focal epilepsy.

Methods: Cross-sectional analysis of data collected in the SAVE study, which included patients with drug-resistant focal epilepsy during long-term EEG monitoring. Patients in whom both coffee consumption and data about seizure frequency, including focal to bilateral tonic-clonic seizures (FBTCS), were available were selected.

Rituximab in combination with adapted-dose of ifosfamide and etoposide as salvage treatment in elderly refractory/relapsed diffuse large B-cell lymphoma patients non-candidate for high dose therapy: a retrospective study.

We retrospectively reviewed for 72 relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) patients ineligible for autologous stem-cell transplantation (ASCT) treated between 2004 and 2017, efficacy and safety profile of rituximab (375 mg/m) in combination with etoposide (300 mg/m) and ifosfamide (1500 mg/m) at 2, 3, or 4-week intervals. Median age was 79 years (range, 64-92). The median number of previous line was 1 (range 1-8).

Chromosomal instability in the prediction of pituitary neuroendocrine tumors prognosis.

The purpose of this study was to analyze the impact of copy number variations (CNV) on sporadic pituitary neuroendocrine tumors (PitNETs) prognosis, to identify specific prognosis markers according to the known clinico-pathological classification. CGH array analysis was performed on 195 fresh-frozen PitNETs (56 gonadotroph, 11 immunonegative, 56 somatotroph, 39 lactotroph and 33 corticotroph), with 5 years post-surgery follow-up (124 recurrences), classified according to the five-tiered grading classification (invasion, Ki-67, mitotic index and p53 positivity). Effect of alterations on recurrence was studied using logistic regression models.

Anti-CASPR2 clinical phenotypes correlate with HLA and immunological features.

Objective: Antibodies against contactin-associated protein-like 2 (CASPR2-Abs) have been described in acquired neuromyotonia, limbic encephalitis (LE) and Morvan syndrome (MoS). However, it is unknown whether these constitute one sole spectrum of diseases with the same immunopathogenesis or three distinct entities with different mechanisms.

Methods: A cluster analysis of neurological symptoms was performed in a retrospective cohort of 56 CASPR2-Abs patients.

Prognostic Significance of Rearrangement and Translocation Partner in Diffuse Large B-Cell Lymphoma: A Study by the Lunenburg Lymphoma Biomarker Consortium.

Purpose: rearrangement (-R) occurs in approximately 10% of diffuse large B-cell lymphomas (DLBCLs) and has been associated with poor prognosis in many studies. The impact of R on prognosis may be influenced by the partner gene (immunoglobulin [IG] or a non-IG gene). We evaluated a large cohort of patients through the Lunenburg Lymphoma Biomarker Consortium to validate the prognostic significance of (single-, double-, and triple-hit status) in DLBCL within the context of the partner gene.

Centralization errors in comparative genomic hybridization array analysis of pituitary tumor samples.

Reliable interpretation of comparative genomic hybridization array (aCGH) results requires centralization and normalization of the data. We evaluated the reliability of aCGH centralization by comparing aCGH results (with classical centralization-normalization steps) to fluorescence in situ hybridization (FISH) results. In addition, we propose a method to correct centralization bias.

Restricted mean survival time over 15 years for patients starting renal replacement therapy.

Background: The restricted mean survival time (RMST) estimates life expectancy up to a given time horizon and can thus express the impact of a disease. The aim of this study was to estimate the 15-year RMST of a hypothetical cohort of incident patients starting renal replacement therapy (RRT), according to their age, gender and diabetes status, and to compare it with the expected RMST of the general population.

Methods: Using data from 67 258 adult patients in the French Renal Epidemiology and Information Network (REIN) registry, we estimated the RMST of a hypothetical patient cohort (and its subgroups) for the first 15 years after starting RRT (cRMST) and used the general population mortality tables to estimate the expected RMST (pRMST).

Familial vs. sporadic sarcoidosis: BTNL2 polymorphisms, clinical presentations, and outcomes in a French cohort.

Background: The occurrence of familial forms of sarcoidosis (OMIM 181100) suggests a genetic predisposition. The involvement of butyrophilin-like 2 (BTNL2) gene (rs2076530 variant) has to be investigated.

Results: The study performed independent analyses of BTNL2 polymorphism, clinical phenotypes, and outcomes in familial vs.

[Cost-effectiveness analysis of various strategies of end-stage renal disease patients' care in France].

End-stage renal disease is a chronic state that may continue for many years before death. Patients may receive various modalities of renal replacement therapy that vary over time, which we describe as a treatment trajectory. The French health insurance system pays dialysis facilities and professionals various fixed fees according to the dialysis modalities they provide; fees are highest for hospital-based haemodialysis care, which treats around 58% of all dialysis patients.

Economic impact of a modification of the treatment trajectories of patients with end-stage renal disease.

Background: This study assumed that some patients currently treated at hospital-based haemodialysis centres can be treated with another renal replacement therapy (RRT) modality without any increase in mortality risk and sought to evaluate the monthly cost impact of replacing hospital-based haemodialysis, for which fees are highest, by different proportions of other modalities.

Methods: We used a deterministic model tool to predict the outcomes and trajectories of hypothetical cohorts of incident adult end-stage renal disease (ESRD) patients for 15 years of RRT (10 different modalities). Our estimates were based on data from 67 258 patients in the REIN registry and 65 662 patients in the French national health insurance information system.

Modelling treatment trajectories to optimize the organization of renal replacement therapy and public health decision-making.

Background: Nephrologists need to better understand the impact of their decisions about long-term treatment strategies. Healthcare planning requires the anticipation of demand. Indicators from ESRD registries are especially difficult to interpret when the underlying dynamic process is not well understood.

A graphical method to assess distribution assumption in group-based trajectory models.

Group-based trajectory models had a rapid development in the analysis of longitudinal data in clinical research. In these models, the assumption of homoscedasticity of the residuals is frequently made but this assumption is not always met. We developed here an easy-to-perform graphical method to assess the assumption of homoscedasticity of the residuals to apply especially in group-based trajectory models.
