A Systematic Review of the Current Evidence from Randomised Controlled Trials on the Impact of Medication Optimisation or Pharmacological Interventions on Quantitative Measures of Cognitive Function in Geriatric Patients
Publisher Copyright: © 2022, The Author(s).Background: Cognitive decline is common in older people. Numerous studies point to the detrimental impact of polypharmacy and inappropriate medication on older peopleâs cognitive function. Here we aim to systematically review evidence on the impact of medication optimisation and drug interventions on cognitive function in older adults. Methods: A systematic review was performed using MEDLINE and Web of Science on May 2021. Only randomised controlled trials (RCTs) addressing the impact of medication optimisation or pharmacological interventions on quantitative measures of cognitive function in older adults (aged > 65 years) were included. Single-drug interventions (e.g., on drugs for dementia) were excluded. The quality of the studies was assessed by using the Jadad score. Results: Thirteen studies met the inclusion criteria. In five studies a positive impact of the intervention on metric measures of cognitive function was observed. Only one study showed a significant improvement of cognitive function by medication optimisation. The remaining four positive studies tested methylphenidate, selective oestrogen receptor modulators, folic acid and antipsychotics. The mean Jadad score was low (2.7). Conclusion: This systematic review identified a small number of heterogenous RCTs investigating the impact of medication optimisation or pharmacological interventions on cognitive function. Five trials showed a positive impact on at least one aspect of cognitive function, with comprehensive medication optimisation not being more successful than focused drug interventions. More prospective trials are needed to specifically assess ways of limiting the negative impact of certain medication in particular and polypharmacy in general on cognitive function in older patients.Peer reviewe
Health enhancing strength training in nonagenarians (STRONG): rationale, design and methods
<p>Abstract</p> <p>Background</p> <p>The Health Enhancing Strength Training in Nonagenarians (STRONG) is a randomised control trial to assess the effectiveness of an aerobic and strength training program for improving muscle strength, functional capacity and quality of life in nonagenarians.</p> <p>Methods</p> <p>Sixty (51 women) nonagenarians (age range: 90â102 years) who live in a geriatric nursing home will be randomly assigned to either a usual care (control) group (n = 30) or an intervention (training) group (n = 30). Participants allocated in the usual care group will receive general physical activity guidelines and participants allocated in the intervention group will also enrol in three weekly non-consecutive individualized training sessions (~45â50 min each) during 8 weeks. The exercise program will consist of muscular strength [with a special focus on leg press at 30% (start of the program) to 70% 1 repetition maximum (end)] and aerobic exercises (cycle-ergometry during 3â5 to 15 minutes at 12â14 points in the rate of perceived exertion scale).</p> <p>Results</p> <p>Results from STRONG will help to better understand the potential of regular physical activity for improving the well-being of the oldest population groups.</p> <p>Conclusion</p> <p>The increase in life expectancy together with the dramatic decrease in birth rates in industrialized countries calls the attention to health care systems and public health policymakers to focus attention on promoting healthy lifestyle in the highest sector of the population pyramid.

Results from STRONG will help to better understand the potential of regular physical activity for improving the well being even in persons aged 90 years or over.</p> <p>Trail Registration</p> <p>ClinicalTrials.gov ID: NCT00848978</p
Autoantibodies against type I IFNs in patients with life-threatening COVID-19
Interindividual clinical variability in the course of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is vast. We report that at least 101 of 987 patients with life-threatening coronavirus disease 2019 (COVID-19) pneumonia had neutralizing immunoglobulin G (IgG) autoantibodies (auto-Abs) against interferon-w (IFN-w) (13 patients), against the 13 types of IFN-a (36), or against both (52) at the onset of critical disease; a few also had auto-Abs against the other three type I IFNs. The auto-Abs neutralize the ability of the corresponding type I IFNs to block SARS-CoV-2 infection in vitro. These auto-Abs were not found in 663 individuals with asymptomatic or mild SARS-CoV-2 infection and were present in only 4 of 1227 healthy individuals. Patients with auto-Abs were aged 25 to 87 years and 95 of the 101 were men. A B cell autoimmune phenocopy of inborn errors of type I IFN immunity accounts for life-threatening COVID-19 pneumonia in at least 2.6% of women and 12.5% of men
Activity in Geriatric acute CARe (AGECAR): Rationale, design and methods
Background: The Activity in GEriatric acute CARe (AGECAR) is a randomised control trial to assess the effectiveness
of an intrahospital strength and walk program during short hospital stays for improving functional capacity of
patients aged 75 years or older.
Methods/Design: Patients aged 75 years or older admitted for a short hospital stay (â€14 days) will be randomly
assigned to either a usual care (control) group or an intervention (training) group. Participants allocated in the usual
care group will receive normal hospital care and participants allocated in the intervention group will perform
multiple sessions per day of lower limb strength training (standing from a seated position) and walking (10 min
bouts) while hospitalized. The primary outcome to be assessed pre and post of the hospital stay will be functional
capacity, using the Short Physical Performance Battery (SPPB), and time to walk 10 meters. Besides length of
hospitalization, the secondary outcomes that will also be assessed at hospital admission and discharge will be
pulmonary ventilation (forced expiratory volume in one second, FEV1) and peripheral oxygen saturation. The
secondary outcomes that will be assessed by telephone interview three months after discharge will be mortality,
number of falls since discharge, and ability to cope with activities of daily living (ADLs, using the Katz ADL score
and Barthel ADL index).
Discussion: Results will help to better understand the potential of regular physical activity during a short hospital
stay for improving functional capacity in old patients. The increase in life expectancy has resulted in a large
segment of the population being over 75 years of age and an increase in hospitalization of this same age group.
This calls attention to health care systems and public health policymakers to focus on promoting methods to
improve the functional capacity of this population.0.586 SJR (2012) Q2, 44/117 Geriatrics and gerontologyUE
Unusual duodenal presentation of leishmaniasis
This case report describes an atypical case of duodenal leishmaniasis in an elderly patient not infected with human immunodeficiency virus. Investigation of this 84 year old woman with a constitutional syndrome and dysphagia revealed anaemia of chronic disorder, a high erythrocyte sedimentation rate, and polyclonal hypergammaglobulinaemia. Abdominal ultrasonography revealed thickening of the stomach wall, which was seen to be inflamed during gastroscopy. Duodenal histology revealed numerous leishmania amastigotes within macrophages. This was confirmed by bone marrow biopsy and leishmania serology. This case report stresses the importance of atypical symptoms and the unusual location of visceral leishmaniasis, not only in immunodepressed patients, but also in elderly immunocompetent patients
What is new in exercise regimes for frail older people â How does the Erasmus Vivifrail Project take us forward?
Short-term, light- to moderate-intensity exercise training improves leg muscle strength in the oldest old: a randomized controlled trial
Our objective was to assess the effects of an 8-week exercise training program with a special focus on light- to moderate-intensity resistance exercises (30-70% of one repetition maximum, 1RM) and a subsequent 4-week training cessation period (detraining) on muscle strength and functional capacity in participants aged 90 and older. We studied a randomized controlled trial performed during March to September 2009. Forty nonagenarians (90-97) were randomly assigned to an intervention or control group (16 women and 4 men per group). We analyzed eight-week muscle strength exercise intervention focused on lower limb strength exercises of light to moderate intensity. we studied handgrip strength, 8-m walk test, 4-step stairs test, Timed Up and Go test, and number of falls. A significant group by time interaction effect (P=.02) was observed only for the 1RM leg press. In the intervention group, 1RM leg press increased significantly with training by 10.6 kg [95% confidence interval (CI)=4.1-17.1 kg; P=.01]. Except for the mean group number of falls, which were 1.2 falls fewer per participant in the intervention group (95% CI=0.0-3.0; P=.03), no significant training effect on the secondary outcome measures was found. In conclusion, exercise training, even of short duration and light to moderate intensity, can increase muscle strength while decreasing fall risk in nonagenarians.3.737 JCR (2011) Q1, 9745 Geriatrics & gerontologyUE
