Four-week administration of an energy and protein dense oral nutritional supplement improves micronutrient concentrations but does not completely correct deficiencies in institutionalized malnourished older adults

Introduction

Poor food intake is common among elderly living in nursing homes, leading to micronutrient deficiency (MD). There are no recommendations for the management of MD in malnourished older adults.

Methods

We conducted a single arm, open-label, multicenter interventional study in institutionalized malnourished older adults to describe the effect of a 4-week daily energy and protein dense oral nutritional supplementation (ONS, 600 kcal, 30 g protein per unit) containing 50% of the recommended daily micronutrient intake on micronutrient status. Plasma concentrations of vitamins (A, B9, B12, C, E), magnesium (Mg), selenium (Se) and zinc (Zn), and erythrocyte vitamin B9 were measured at baseline and after 4 weeks.

Results

Forty-six participants completed the study (age 87.4 ± 6.6). At baseline, the most frequent MD were Se (48%), Zn (35%), Mg (24%) and vitamin C (24%). Plasma concentrations of vitamins B9, B12, C and E, Mg, Se and Zn significantly increased and the proportion of subjects with at least one MD decreased (p = 0.006). However, after 4 weeks, 40% of subjects still had at least one MD.

Discussion

ONS consumption improved micronutrient status but did not correct MD in all participants. Our data suggest that the prescription of vitamin, mineral and trace element supplementation should be considered in institutionalized malnourished older adults in addition to high energy and high protein ONS.

[Evaluation of the perspectives and experiences regarding lumbar puncture in cognitively impaired older adults over 70, their relatives and the care teams]

INTRODUCTION

Lumbar puncture (LP) is an essential diagnostic procedure, which raises major concerns in older adults. Some patients may be denied LP because of the fear of complications in healthcare teams which are not familiar with the procedure. The objectives of our work were to analyze the perspectives and the experiences regarding scheduled LP in cognitively impaired older adults, as well as in their relatives, and the healthcare teams from geriatric day hospitals.

METHODS

We conducted a qualitative, observational and multicentric study, based on semi-directive interviews of patients aged over 70 years with cognitive complaints undergoing a scheduled LP in a day hospital. Patients were interviewed before and after LP. Their relatives and the involved healthcare teams were also interviewed to analyze their expectations and perspectives regarding the procedure. The full interviews were transcribed and analyzed using interpretative phenomenological analysis.

RESULTS

Ten patients (mean age 80.2 ± 7.2), five relatives and four healthcare teams were included. The goals and operating procedure of LP were poorly understood by several patients. Some individuals feared irreversible neurological consequences or LP-related pain, which was often overestimated with regards to the post-LP interviews. The patients' major expectation was to establish an accurate and early diagnosis of their cognitive disorder to provide optimal care plan. Relatives reported similar fears of major adverse events. They also expected an accurate diagnosis with biomarkers. The perspectives and experiences of the healthcare teams were heterogeneous, according to their level of practice of LP, but seemed in line with current scientific guidelines.

CONCLUSION

This study highlighted the existence of false beliefs and poor knowledge regarding the LP procedure and its associated risks. The post-LP patients' feedbacks were better than their expectations, especially in day hospitals with solid experience in LP. Better patient information may be a key to improve our practice.

COVID-19 as an Independent Risk Factor for Weight Loss in Older Adults Living in Nursing Homes

INTRODUCTION

In nursing homes, where residents are at elevated risk for malnutrition, the specific additive effect of the coronavirus disease 2019 (COVID-19) on weight loss has not yet been adequately evaluated. This study aimed to determine the factors independently associated with weight loss in nursing home residents who survived the first wave of the COVID-19 pandemic, whether they have contracted COVID-19 or not.

METHODS

This research was a retrospective study conducted in three nursing homes. Residents who survived the first French COVID-19 lockdown (March to May 2020) were included, provided their weight records were available. Baseline data included the body mass index (BMI), capacity to self-feed, need for texture-modified food, disability, and legal guardianship status. The diagnosis of COVID-19 was based on the results of a positive reverse transcriptase-polymerase chain reaction test. Univariate and multivariate logistic regression analyses were used to investigate associations between resident characteristics, COVID-19 status, and at least 5% weight loss.

RESULTS

Of the 316 included residents (72% female, mean age of 88 years, 48% severely disabled, and 38% under legal guardianship), 111 (35%) contracted COVID-19 and 102 (32%) lost at least 5% of their body weight. No difference was observed between the baseline characteristics of residents subsequently affected or unaffected by COVID-19. In the univariate analysis, old age, severe disability, texture-modified food, the need for close mealtime supervision, and COVID-19 were significantly associated with at least 5% weight loss. In the multivariate logistic regression analysis, COVID-19 (p = 0.02) and the need for close mealtime supervision (p = 0.02) were associated with weight loss in a model that also included age, BMI, texture-modified food, disability, and nursing home.

CONCLUSION

For nursing home residents, COVID-19 was an independent risk factor for weight loss. Weight loss was most common in residents needing close mealtime supervision, suggesting that organizational issues may have affected the quality of the nutritional care provided during the lockdown.

[Screening and diagnosis of undernutrition in adults in daily practice]

SCREENING AND DIAGNOSIS OF UNDERNUTRITION IN ADULTS IN DAILY PRACTICE Following an international expert consensus, the French National Authority for Health has revised the diagnostic criteria for undernutrition for adults -70 years (2019) and for adults 70 years (2021). The diagnosis of undernutrition is based on the combination of a phenotypic criterion and an etiological criterion. The phenotypic criteria as follows: weight loss, Body Mass Index (BMI) and criteria concerning muscle strength, muscle mass and physical performance. The aetiological criteria are three: decreased food intake, disturbed digestive absorption and acute or chronic pathologies leading to hypercatabolism. Hypoalbuminemia is no longer a diagnostic criterion for undernutrition, but it reflects its severity. Apart from BMI, these criteria also apply to obese people.

Hypnosis for pain and anxiety management in cognitively impaired older adults undergoing scheduled lumbar punctures: a randomized controlled pilot study

Background

Core cerebrospinal fluid (CSF) amyloid and tau biomarker assessment has been recommended to refine the diagnostic accuracy of Alzheimer’s disease. Lumbar punctures (LP) are invasive procedures that might induce anxiety and pain. The use of non-pharmacological techniques must be considered to reduce the patient’s discomfort, in this setting. The objective of this study was to examine the efficacy of hypnosis on anxiety and pain associated with LP.

Methods

A monocentric interventional randomized-controlled pilot study is conducted in a university geriatric day hospital. Cognitively impaired patients aged over 70 were referred for scheduled LP for the diagnostic purpose (CSF biomarkers). The participants were randomly assigned either to a hypnosis intervention group or usual care. Pain and anxiety were both self-assessed by the patient and hetero-evaluated by the operator.

Results

We included 50 cognitively impaired elderly outpatients (women 54%, mean age 77.2 ± 5.0, mean Mini-Mental State Examination score 23.2 ± 3.5). Hypnosis was significantly associated with reduced self-assessed (p < 0.05) and hetero-assessed anxiety (p < 0.01). Hetero-evaluated pain was significantly lower in the hypnosis group (p < 0.05). The overall perception of hypnosis was safe, well-accepted, and feasible in all the participants of the intervention group with 68% perceiving the procedure as better or much better than expected.

Conclusions

This pilot study suggested that hypnosis was feasible and may be used to reduce the symptoms of discomfort due to invasive procedures in older cognitively impaired patients. Our results also confirmed the overall good acceptance of LP in this population, despite the usual negative perception.

Corticosteroid therapy in COVID-19 associated with in-hospital mortality in geriatric patients: a propensity matched cohort study

Background

Few data are available on the prognosis of older patients who received corticosteroids for COVID-19. We aimed to compare the in-hospital mortality of geriatric patients hospitalized for COVID-19 who received corticosteroids or not.

Methods

We conducted a multicentric retrospective cohort study in 15 acute COVID-19 geriatric wards in the Paris area from March to April 2020 and November 2020 to May 2021. We included all consecutive patients aged 70 years and older who were hospitalized with confirmed COVID-19 in these wards. Propensity score and multivariate analyses were used.

Results

Of the 1 579 patients included (535 received corticosteroids), the median age was 86 (interquartile range 81–91) years, 56% of patients were female, the median Charlson Comorbidity Index (CCI) was 2.6 (interquartile range 1–4), and 64% of patients were frail (Clinical Frailty Score 5–9). The propensity score analysis paired 984 patients (492 with and without corticosteroids). The in-hospital mortality was 32.3% in the matched cohort. On multivariate analysis, the probability of in-hospital mortality was increased with corticosteroid use (odds ratio [OR] = 2.61 [95% confidence interval (CI) 1.63–4.20]). Other factors associated with in-hospital mortality were age (OR = 1.04 [1.01–1.07], CCI (OR = 1.18 [1.07–1.29], activities of daily living (OR = 0.85 [0.75–0.95], oxygen saturation < 90% on room air (OR = 2.15 [1.45–3.17], C-reactive protein level (OR = 2.06 [1.69–2.51], and lowest lymphocyte count (OR = 0.49 [0.38–0.63]). Among the 535 patients who received corticosteroids, 68.3% had at least one corticosteroid side effect, including delirium (32.9%), secondary infections (32.7%), and decompensated diabetes (14.4%).

Conclusions

In this multicentric matched-cohort study of geriatric patients hospitalized for COVID-19, the use of corticosteroids was significantly associated with in-hospital mortality.

[Lipid pneumonitis, a serious iatrogenic event with lubricating laxatives]

The prescription of lubricating laxatives (paraffin oil) is widespread in geriatrics because of the frequency of constipation. These molecules can cause serious adverse effects such as lipoid pneumonia, especially in subjects with swallowing disorders.
