[Oral administration of medicines in elderly patients and adaptation of galenic forms]. / Prise orale de médicaments chez les patients âgés et adaptations galéniques.

Physiological ageing and pathologies can have an influence on the pharmacology of numerous medicines, leading to serious iatrogenic accidents, polypharmacy and incorrect use of a medicine in elderly people. An observational study carried out in a short-stay geriatric unit focused on the issues surrounding the difficulties the elderly may encounter when taking medicines and the prevalence of the manipulation of galenic forms.

[Orthostatic hypotension in elderly: a case-control study]. / Hypotension orthostatique chez le sujet âgé : une étude cas-témoins.

Orthostatic hypotension is common in the elderly and is often associated with increased morbidity and mortality. Compression bandages are recommended as a first-line treatment but there is little evidence of their efficacy in literature. A case-control study involving 52 patients was carried out to test the efficacy of the bandages. In the group with orthostatic hypotension, compression improved the symptoms without correcting the blood pressure readings.

Clinical Characteristics and Outcomes of 821 Older Patients With SARS-Cov-2 Infection Admitted to Acute Care Geriatric Wards.

BACKGROUND: There is limited information describing the characteristics and outcomes of hospitalized older patients with confirmed coronavirus disease 2019 (COVID-19). METHOD: We conducted a multicentric retrospective cohort study in 13 acute COVID-19 geriatric wards, from March 13 to April 15, 2020, in Paris area. All consecutive patients aged 70 years and older, with confirmed COVID-19, were enrolled. RESULTS: Of the 821 patients included in the study, the mean (SD) age was 86 (7) years; 58% were female; 85% had ≥2 comorbidities; 29% lived in an institution; and the median [interquartile range] Activities of Daily Living scale (ADL) score was 4 [2-6]. The most common symptoms at COVID-19 onset were asthenia (63%), fever (55%), dyspnea (45%), dry cough (45%), and delirium (25%). The in-hospital mortality was 31% (95% confidence interval [CI] 27-33). On multivariate analysis, at COVID-19 onset, the probability of in-hospital mortality was increased with male gender (odds ratio [OR] 1.85; 95% CI 1.30-2.63), ADL score <4 (OR 1.84; 95% CI 1.25-2.70), asthenia (OR 1.59; 95% CI 1.08-2.32), quick Sequential Organ Failure Assessment score ≥2 (OR 2.63; 95% CI 1.64-4.22), and specific COVID-19 anomalies on chest computerized tomography (OR 2.60; 95% CI 1.07-6.46). CONCLUSIONS: This study provides new information about older patients with COVID-19 who are hospitalized. A quick bedside evaluation at admission of sex, functional status, systolic arterial pressure, consciousness, respiratory rate, and asthenia can identify older patients at risk of unfavorable outcomes.

Prophylaxis of Venous Thromboembolism in Geriatric Settings: A Cluster-Randomized Multicomponent Interventional Trial.

OBJECTIVES: To evaluate the efficacy of an intervention on the practice of venous thromboembolism prevention. DESIGN: A multicenter, prospective, controlled, cluster-randomized, multifaceted intervention trial consisting of educational lectures, posters, and pocket cards reminding physicians of the guidelines for thromboprophylaxis use. SETTINGS: Twelve geriatric departments with 1861 beds total, of which 202, 803, and 856 in acute care, post-acute care, and long-term care wards, respectively. PARTICIPANTS: Patients hospitalized between January 1 and May 31, 2015, in participating departments. MEASUREMENTS: The primary endpoint was the overall adequacy of thromboprophylaxis prescription at the patient level, defined as a composite endpoint consisting of indication, regimen, and duration of treatment. Geriatric departments were divided into an intervention group (6 departments) and control group (6 departments). The preintervention period was 1 month to provide baseline practice levels, the intervention period 2 months, and the postintervention period 1 month in acute care and post-acute care wards or 2 months in long-term care wards. Multivariable regression was used to analyze factors associated with the composite outcome. RESULTS: We included 2962 patients (1426 preintervention and 1536 postintervention), with median age 85 [79;90] years. For the overall 18.9% rate of inadequate thromboprophylaxis, 11.1% was attributable to underuse and 7.9% overuse. Intervention effects were more apparent in post-acute and long-term care wards although not significantly [odds ratio 1.44 (95% confidence interval 0.78;2.66), P = .241; and 1.44 (0.68, 3.06), P = .345]. Adequacy rates significantly improved in the postintervention period for the intervention group overall (from 78.9% to 83.4%; P = .027) and in post-acute care (from 75.4% to 86.3%; P = .004) and long-term care (from 87.0% to 91.7%; P = .050) wards, with no significant trend observed in the control group. CONCLUSIONS/IMPLICATIONS: This study failed to demonstrate improvement in prophylaxis adequacy with our intervention. However, the intervention seemed to improve practices in post-acute and long-term care but not acute care wards.

B12 deficiency increases with age in hospitalized patients: a study on 14,904 samples.

BACKGROUND: Cobalamin deficiency is responsible for hematological, neurological, neurocognitive, and neuropsychiatric impairments and is a risk factor for cardiovascular diseases, particularly in the elderly people. METHODS: In order to determine B12 status in old inpatients, a total number of 14,904 hospitalized patients in whom B12 measurements were performed in five hospitals in the Paris metropolitan area were included from January 1, 2011 to December 31, 2011. The aims of the study were to determine whether age had an impact on B12 and folate deficiencies and to evaluate correlations between B12 and biological parameters-folate, hemoglobin, mean cell volume, homocystein (tHcy)-and age. RESULTS: Patients were aged 70.3±19.5 years. Low B12 concentration (<200ng/L) was observed in 4.6% of cases, 24.2% had middle B12 concentration (200-350ng/L), 12.6% were functional B12 deficient (B12 < 350 ng/L associated to high tHcy level, tHcy > 17 µmol/L), 20.4% had low folate concentration (folate < 4 µg/L), 10.6% were functional folate deficient (folate < 4 µg/L associated to tHcy > 17 µmol/L), and 4.7% of patients were both functional B12 and folate deficient. The B12 or folate deficient patients had lower mean cell volume level than nondeficient patients. Increase in mean cell volume and tHcy concentrations with age and decrease in B12, folate, and hemoglobin levels with age were observed. Frequency of functional B12 deficiency was 9.6% in patients aged 30-60 years and 14.2% in patients over 90 years. Frequency of functional folate deficiency was 9.5% in 30-60 years and 12.1% in >90 years. CONCLUSIONS: In inpatients, functional B12 deficiency and functional folate deficiency increase with age and are not associated with anemia or macrocytosis. False vitamin B deficiencies are frequent.

[Which vaccination and cardiovascular prevention in elderly?]. / Quelle prévention vaccinale et cardiovasculaire peut-on conseiller aux sujets âgés ?

Vaccination especially influenza, tetanus and pneumococcus should be used by the physician as an effective preventive measure. Stop smoking prevents the occurrence of cardiovascular event as the control of blood pressure in elderly healthy. It is very important to treat atrial fibrillation in elderly. In elderly aged over 80 years, primary prevention of dyslipidemia by statins is controversial whereas secondary prevention of cardiovascular events by statins is effective.

[Senile systemic amyloidosis: definition, diagnosis, why thinking about?]. / Amylose systémique sénile : définition, diagnostic, pourquoi y penser ?

Senile systemic amyloidosis (SSA) is characterized by infiltration of amyloid transthyretin fibrils in the myocardium. SSA occurs mainly (but not always) in elderly men. SSA leads to hypertrophic and/or restrictive cardiomyopathy complicated by conduction disturbances, atrial arrhythmia and systemic embolization (stroke…). That is why SSA needs a special care and to be diagnosed. Cardiac SSA diagnosis needs to exclude two other forms of cardiac amyloidosis: AL amyloidosis (light chain) and hereditary transthyretin amyloidosis (genetic testing). Scintigraphic 99mTc-DPD heart retention is observed in cardiac amyloidosis. DPD heart retention is more frequent in cardiac transthyretin amyloidosis than in cardiac AL amyloidosis. Specific treatments of cardiac TTR amyloidosis are in development.

Results of noninvasive ventilation in very old patients.

BACKGROUND: Noninvasive ventilation (NIV) is frequently used for the management of acute respiratory failure (ARF) in very old patients (≥ 80 years), often in the context of a do-not-intubate order (DNI). We aimed to determine its efficacy and long-term outcome. METHODS: Prospective cohort of all patients admitted to the medical ICU of a tertiary hospital during a 2-year period and managed using NIV. Characteristics of patients, context of NIV, and treatment intensity were compared for very old and younger patients. Six-month survival and functional status were assessed in very old patients. RESULTS: During the study period, 1,019 patients needed ventilatory support and 376 (37%) received NIV. Among them, 163 (16%) very old patients received ventilatory support with 60% of them managed using NIV compared with 32% of younger patients (p < 0.0001). Very old patients received NIV more frequently with DNI than in younger patients (40% vs. 8%). Such cases were associated with high mortality for both very old and younger patients. Hospital mortality was higher in very old than in younger patients but did not differ when NIV was used for cardiogenic pulmonary edema or acute-on-chronic respiratory failure (20% vs. 15%) and in postextubation (15% vs. 17%) out of a context of DNI. Six-month mortality was 51% in very old patients, 67% for DNI patients, and 77% in case of NIV failure and endotracheal intubation. Of the 30 hospital survivors, 22 lived at home and 13 remained independent for activities of daily living. CONCLUSIONS: Very old patients managed using NIV have an overall satisfactory 6-month survival and functional status, except for endotracheal intubation after NIV failure.

Comprehensive geriatric assessment in the decision-making process in elderly patients with cancer: ELCAPA study.

PURPOSE: To identify Comprehensive Geriatric Assessment (CGA) components independently associated with changes in planned cancer treatment. PATIENTS AND METHODS: We prospectively included 375 consecutive elderly patients with cancer (ELCAPA01 study) assessed by geriatricians using the CGA. Multivariate analysis was used to identify factors associated with changes in the cancer treatment (intensification, decrease, or delayed > 2 weeks). Change was defined as a difference between the initial treatment proposal and the final treatment selected in a multidisciplinary meeting. RESULTS: Mean age was 79.6 years (standard deviation [SD], 5.6 years), and 197 (52.5%) were women. The most common tumor location was the digestive system (58.7%). The mean number of comorbidities was 4.2 (SD, 2.7) per patient, and the mean Cumulative Illness Rating Scale for Geriatrics score was 11.8 (SD, 5.3). After the CGA, the initial cancer treatment plan was modified for 78 (20.8%) of 375 patients (95% CI, 16.8 to 25.3), usually to decrease treatment intensity (63 [80.8%] of 78 patients). By univariate analysis, cancer treatment changes were associated with Eastern Cooperative Oncology Group performance status ≥ 2 (73.3% in the group with changes v 41.1% in the in the group without changes; P < .001), dependency for one or more activities of daily living (ADL; 59.0% v 24.2%; P < .001), malnutrition (81.8% v 51.2%; P < .001), cognitive impairment (38.5% v 24.9%; P = .023), depression (52.6% v 21.7%; P < .001), and greater number of comorbidities (mean, 4.8 [SD, 2.9] v 4.0 [SD, 2.6]; P = .02). By multivariate analysis, factors independently associated with cancer treatment changes were a lower ADL score (odds ratio [OR], 1.25 per 0.5-point decrease; CI, 1.04 to 1.49; P = .016) and malnutrition (OR, 2.99; CI, 1.36 to 6.58; P = .007). CONCLUSION: Functional status assessed by the ADL score and malnutrition were independently associated with changes in cancer treatment.
