[Frequency of incidentalomas on computed tomography scans in the hospitalised elderly]. / Fréquence des incidentalomes sur les imageries en coupe par tomodensitométrie du sujet âgé hospitalisé.

INTRODUCTION: Incidentaloma is the result of the medical problem created by the development of imaging. Without a universal definition, incidentaloma describes any incidental finding revealed by a medical examination performed for another indication, and which will be the origin of a questioning intended to give it a clinical meaning. The frequency of incidentalomas is very variable depending on the imaging technique, the organ affected and the definition used. The aim of this study was to investigate the frequency of incidentalomas on computed tomography (CT) scans in a geriatric hospitalised population. METHODS: In an observational, retrospective, monocentric study, we analysed, for a full year, all the planned CT scans performed, during a hospitalisation in acute and subacute care service of a Parisian geriatric hospital in search of incidentalomas. RESULTS: 113 patients were included in the study, with a mean age of 87,4 years. The frequency of incidentalomas on CT scans in this population was 53 %, with an average of two incidentalomas per patient. Eight percent of the incidentalomas required further examination, specialist advice or treatment. We found incidentalomas in half of the brain and abdomino-pelvic CT scans and in a quarter of the chest CT scans. Age was not associated with the presence of incidentalomas. DISCUSSION: Incidentaloma has become an important part of current medical practice. The geriatrician must know how to anticipate it and propose to his patient an adapted management.

[Heart failure treatments]. / Les traitements de l'insuffisance cardiaque.

Heart failure is a frequent pathology in the elderly. In particular, it is responsible for many hospitalizations. A distinction is made between chronic and acute forms of heart failure. The management of these forms of heart failure is well established, with treatment recommendations that are regularly updated on the basis of new studies.

Real-life impact of respiratory panel PCR assay on antibiotic prescription in geriatric acute care in the pre-COVID-19 era.

OBJECTIVES: In this era of bacterial resistance, avoiding inappropriate use of antibiotic treatments is of major importance. Respiratory tract infections are frequent among older patients, and differentiating viral from bacterial infections is a challenge. The aim of our study was to evaluate the impact of recently available respiratory PCR testing on antimicrobial prescription in geriatric acute care. METHODS: We performed a retrospective study, including all hospitalized geriatric patients who had had multiplex respiratory PCR testing prescribed from 1st October 2018 to 30th September 2019. The PCR test comprised a respiratory viral panel (RVP) and a respiratory bacterial panel (RBP). PCR testing could be prescribed at any time during hospitalization by geriatricians. Our primary endpoint was antibiotic prescription after viral multiplex PCR testing results. RESULTS: All in all, 193 patients were included, 88 (45.6%) of whom had positive RVP, while none had positive RBP. Patients with positive RVP had significantly fewer antibiotic prescriptions following test results than patients with negative RVP (odds ratio (OR) 0.41, 95% confidence interval (CI) 0.22-0.77; p = 0.004). Among positive-RVP patients, factors associated with antibiotic continuation were presence of radiological infiltrate (OR 12.02, 95%CI 3.07-30.29), and detected Respiratory Syncytial Virus (OR 7.54, 95%CI 1.74-32.65). That said, discontinuation of antibiotic treatment seems safe. CONCLUSION: In this population, the impact of viral detection by respiratory multiplex PCR on antibiotic therapy was low. It could be optimized by means of clearly formulated local guidelines, qualified staff and specific training by infectious disease specialists. Cost-effectiveness studies are necessary.

Critical Assessment of Metagenome Interpretation-a benchmark of metagenomics software.

Methods for assembly, taxonomic profiling and binning are key to interpreting metagenome data, but a lack of consensus about benchmarking complicates performance assessment. The Critical Assessment of Metagenome Interpretation (CAMI) challenge has engaged the global developer community to benchmark their programs on highly complex and realistic data sets, generated from ∼700 newly sequenced microorganisms and ∼600 novel viruses and plasmids and representing common experimental setups. Assembly and genome binning programs performed well for species represented by individual genomes but were substantially affected by the presence of related strains. Taxonomic profiling and binning programs were proficient at high taxonomic ranks, with a notable performance decrease below family level. Parameter settings markedly affected performance, underscoring their importance for program reproducibility. The CAMI results highlight current challenges but also provide a roadmap for software selection to answer specific research questions.

[First year prognosis of patients hospitalized in an acute geriatric ward with a known dementia or newly diagnosed]. / Devenir à un an des patients hospitalisés en court séjour gériatrique, avec un syndrome démentiel connu, ou nouvellement diagnostiqué.

In France, only a third of demented patients have an established diagnostic of dementia. Hospitalization is often an opportunity to perform a diagnostic of dementia. Real benefits for patients of such a diagnostic process are unknown. The objective of the study was to observe prognosis of elderly patients hospitalized in geriatric courses in terms of mortality, hospitalization rate and entry into an institution. This was a monocentric prospective study with a one-year follow-up of 90 patients hospitalized in an acute geriatric ward with either dementia known by general practitioner, either diagnosed during the hospitalization according to DSM IV criteria. A one year follow-up by phone has been conducted. From a consecutive set of 159 inpatients for 18 weeks, we included in this study 49 patients with a known dementia (group 1, mean age 85.7±4.6 years, mean Mini-mental state examination (MMSE) score 12.4±6.2) and 41 patients with dementia diagnosed during hospitalization (group 2, mean age 88.4±6.4 years, mean MMSE score 16.1±6.5). Differences between the two groups were significant for age (p<0.03) and MMSE score (p<0.02). One-year mortality rate was near 30% in the 2 groups. Rate of institutionalization was 33% in group 1 and 49% in group 2 (not statistically significant). There was a significant difference in number of days spent at home between group 1 and group 2, respectively 190.9±159.9 days vs 111.1±148.1 days (p<0.03). Demented patients previously diagnosed lived longer at home at one year than patients newly diagnosed. These results tend to support the diagnosis of dementia in very elderly patients with multiple comorbidities. Conditions of living at home, in particular the quality of life, should be the object of further studies.

Patterns of loss of abilities in instrumental activities of daily living in Alzheimer's disease: the REAL cohort study.

BACKGROUND/AIMS: To determine patterns of loss of abilities in instrumental activities of daily living (IADL) in community-dwelling women with Alzheimer's disease (AD). METHODS: Sixteen French university hospitals included 471 consecutive women with mild to moderately severe AD (Mini-Mental State Examination scores between 10 and 26) from April 2000 to June 2002 in the noninterventional REAL cohort. At inclusion, 6 and 12 months, IADL were assessed with the Lawton scale. Patterns of loss of abilities in the 8 IADL of the Lawton scale were described using Lawton binary grading. RESULTS: At inclusion, 56.7% of the patients shared the same pattern of loss of abilities and 84.3% had this pattern or variants of it. Frequencies of the 8 incapacities were: 80.7% to do the grocery shopping, 76.0% to take medication, 72.2% to prepare meals, 41.4% to travel on public transportation even when assisted, 40.6% to manage purchases, 30.1% to launder small items, 14.2% to participate in some housekeeping tasks and 11.0% to answer the telephone. CONCLUSION: In this study including 471 community-dwelling women with AD of the French REAL cohort, the loss of the 8 IADL, assessed with the Lawton binary grading, was homogeneous for more than four fifths of the patients.
