Objectives: The increase in polypharmacy among older adults increases the risk of drug-related problems, making multidisci-plinary interventions essential. This study evaluated the impact of a multidisciplinary polypharmacy consultation on medicationmanagement and outcomes in older outpatients.Methods: This prospective observational study at a Spanish teaching hospital involved geriatricians, clinical pharmacists, andnurses. Older adults (≥ 75 years) with polypharmacy underwent medication review at baseline and at 3 and 6 months. Data onmedication use, adherence to Screening Tool of Older Person's Prescriptions (STOOP) criteria, and anticholinergic burden wereanalyzed.Results: The study included 104 older adults (mean age 86.2 years; 66% female). An average of 3.6 recommendations per par-ticipant was made (63.8% acceptance rate). Common drug-related problems were adverse effects (20%), non-adherence (18.1%), and incorrect dose/regimen (14.4%). Interventions led to an average reduction of 1.7 medications per patient, with 1.3 dosage orregimen changes and 1.1 new prescriptions. The mean number of medications decreased from 9.6 at baseline to 8.9 at 3 months(p < 0.001) and remained below baseline at 6 months. STOPP criteria violations per patient dropped from 1.2 to 1.0 (p = 0.036). Of the 126 medications flagged by STOPP criteria, 68.3% were addressed, 24.6% discontinued, mainly psychotropics, and 89.3%of these discontinuations were maintained. The anticholinergic burden decreased from 1.3 to 1.1 at 3 months (p = 0.036) andremained below baseline at 6 months.Conclusions: A multidisciplinary clinic effectively managed polypharmacy in older adults by reducing medication load andimproving appropriateness per STOPP criteria, highlighting the importance of proactive medication management.Trial Registration: ClinicalTrials.gov: NCT05408598 (March 1, 2022).

Identifying serum biomarkers that can predict physical frailty in older adults would have tremendous clinical value for primary care, as this condition is inherently related to poor quality of life and premature mortality. We compared the serum lipid profile of physically frail and robust older adults to identify specific lipid biomarkers that could be used to assess physical frailty in older patients at hospital admission. Forty-three older adults (58.1% male), mean (range) age 86.4 (78–100 years) years, were classified as physically frail (n = 18) or robust (n = 25) based on scores from the Short Physical Performance Battery (≤ 6 points). Non-targeted metabolomic study by ultra-high performance liquid chromatography coupled to mass spectrometry (UHPLC-MS) analysis with later bioinformatics data analysis. Once the significantly different metabolites were identified, the KEGG database was used on them to establish which were the metabolic pathways mainly involved. Area under receiver-operating curve (AUROC) analysis was used to test the discriminatory ability of lipid biomarkers for frailty based on the Short Physical Performance Battery. We identified a panel of five metabolites including ceramides Cer (40:2), Cer (d18:1/20:0), Cer (d18:1/23:0), cholesterol, and hosphatidylcholine (PC) (14:0/20:4) that were significantly increased in physically frail older adults compared with robust older adults at hospital admission. The most interesting in the physically frail metabolome study found with the KEGG database were the metabolic pathways, vitamin digestion and absorption, AGE-RAGE signaling pathway in diabetic complications, and insulin resistance. In addition, Cer (40:2) (AUROC 0.747), Cer (d18:1/23:0) (AUROC 0.720), and cholesterol (AUROC 0.784) were identified as higher values of physically frail at hospital admission. The non-targeted metabolomic study can open a wide view of the physically frail features changes at the plasma level, which would be linked to the physical frailty phenotype at hospital admission. Also, we propose that metabolome analysis will have a suitable niche in personalized medicine for physically frail older adults.

We aimed to examine the effects of an individualised multicomponent exercise program on functional outcomes in hospitalised older patients with cancer. Patients aged ¿ 65 were recruited upon admission to a Medical Oncology Department and randomly allocated to receive a multicomponent exercise training program twice daily for five days or standard hospital care. The primary outcome measure was the change in functional status using the Short Physical Performance Battery. This study allocated 30 patients in the Control group and 28 in the intervention group. The mean age was 74.4 years. The intervention group (n = 14) showed significant improvements vs the Control group (n = 20) in the Short Physical Performance Battery (SPPB) (between-group difference, 1.92; 95% CI = 0.80,3.07), knee extension strength (between-group difference 7.72; 95% CI = 1.83,13.8), as well as a significant reduction in fatigue (between-group difference —26.5; 95% CI = —38.6,—13.9). This individualised exercise program appears to have contributed to improving functional abilities and reducing fatigue in hospitalised older cancer patients.

Background Hospital-associated functional decline affects nearly one-third of the hospitalized older adults. The aim of this trial is to investigate the effect of a cognitive stimulation intervention provided via immersive virtual reality (IVR), with or without a multicomponent physical exercise intervention (ME) in hospitalized patients aged 75 or older with severe functional dependency at admission (Barthel Index <60 points). Methods This clinical randomized controlled trial will be conducted in the Acute Geriatric Unit of a tertiary hospital in Spain. A total of 212 acute patients will be enrolled according to the following criteria: age ≥75, Barthel Index <60, able to collaborate, expected length of stay ≥5 days, absence of clinical instability and severe dementia (Global Deterioration Scale 7) or other end-stage disease. Patients will be randomly assigned to a control group (CG) or any of the three intervention groups (IG): IVR, ME, or IVR + ME. The IVR group will watch ad-hoc videos showing Spanish regional landscapes and villages, approximately 4 min per day for three consecutive days. The ME group will undergo aerobic and strength exercise for progressive training of the upper and lower limbs. The IVR + ME group will do both cognitive and physical intervention. The primary outcomes will be cognitive and physical measures at discharge. Mood, quality of life, isometric strength, and acceptance of IVR will be also assessed. Discussion This project has the potential to enhance physical and psychological well-being of patients with severe functional dependency hospitalized for acute conditions, using technology. Virtual reality is expected to be favourably perceived by hospitalized older adults. This intervention represents a novelty in the geriatric patients¿ care, comprising IVR and/or ME dispensed within the patient¿s room, and including patients who are commonly excluded from research clinical trials.

Background/Objectives: In primary care, tailored physical activity and nutritional counselling are scarce for older adults. Several challenges contribute to this issue, the primary obstacle being limited access to expert healthcare providers. The purpose of this study was to propose a quick, easy-to-implement case-finding tool offering straightforward nutritional and physical activity counselling to overcome these barriers. Methods: Crosssectional, baseline analysis was performed on 277 participants of the Cognitive Function and Amyloid Marker in Frail Older Adults (COGFRAIL) study, aged 70 years and older with mild cognitive impairment (mini-mental state examination score ≥ 20) and autonomy in daily living activities (ADL ≥ 4). Body composition was assessed using dual-energy X-ray absorptiometry, physical function was assessed using the short physical performance battery (SPPB), and nutrition was assessed using the mini nutritional assessment (MNA). A structured dietary interview was conducted to collect data on a typical daily intake pattern. A second database of 725 autonomous frail older adults from the Frailty clinic was used to test the robustness of the findings. Results: Participants with MNA scores < 24/30 and SPPB scores < 6/12 presented a high percentage of protein (74.1%) and caloric (66.7%) deficiency compared to the other categories. Based on standard daily protein and caloric recommendations, age, and weight, this category had a daily protein-caloric deficit of −19.4 ± 22.7 g and −225.5 ± 430.1 Kcal. Conclusions: Based on the data, an easy-to-use algorithm using MNA and SPPB scores is suggested. This algorithm could serve as an effective tool for guiding nutritional and physical activity counselling for communitydwelling older adults.

Background Physical exercise is benefcial to reduce the risk of several conditions associated with advanced age, but to our knowledge, no previous study has examined the association of long-term exercise interventions (≥1 year) with the occurrence of dropouts due to health issues and mortality, or the efectiveness of physical exercise versus usual primary care interventions on health-related outcomes in older adults (≥ 65 years old). Objective To analyze the safety and efectiveness of long-term exercise interventions in older adults. Methods We conducted a systematic review with meta-analysis examining the association of long-term exercise interventions (≥1 year) with dropouts from the corresponding study due to health issues and mortality (primary endpoint), and the efects of these interventions on health-related outcomes (falls and fall-associated injuries, fractures, physical function, quality of life, and cognition) (secondary endpoints). Results Ninety-three RCTs and six secondary studies met the inclusion criteria and were included in the analyses (n=28,523 participants, mean age 74.2 years). No diferences were found between the exercise and control groups for the risk of dropouts due to health issues (RR=1.05, 95% CI 0.95–1.17) or mortality (RR=0.93, 95% CI 0.83–1.04), although a lower mortality risk was observed in the former group when separately analyzing clinical populations (RR=0.67, 95% CI 0.48–0.95). Exercise signifcantly reduced the number of falls and fall-associated injuries, and improved physical function and cognition. These results seemed independent of participants’ baseline characteristics (age, physical function, and cognitive status) and exercise frequency. Conclusions Long-term exercise training does not overall infuence the risk of dropouts due to health issues or mortality in older adults, and results in a reduced mortality risk in clinical populations. Moreover, exercise reduces the number of falls and fall-associated injuries, and improves physical function and cognition in this population.
