Acute illness requiring hospitalization frequently is a sentinel event leading to long-term disability in older people. Prolonged bed rest increases the risk of developing cognitive impairment and ...dementia in acutely hospitalized older adults. Exercise protocols applied during acute hospitalization can prevent functional decline in older patients, but exercise benefits on specific cognitive domains have not been previously investigated. We aimed to assess the effects of a multicomponent exercise intervention for cognitive function in older adults during acute hospitalization.
We performed a secondary analysis of a single-blind randomized clinical trial (RCT) conducted from February 1, 2015, to August 30, 2017 in an Acute Care of the Elderly (ACE) unit in a tertiary public hospital in Navarre (Spain). 370 hospitalized patients (aged ≥75 years) were randomly allocated to an exercise intervention (n = 185) or a control (n = 185) group (usual care). The intervention consisted of a multicomponent exercise training program performed during 5-7 consecutive days (2 sessions/day). The usual care group received habitual hospital care, which included physical rehabilitation when needed. The main outcomes were change in executive function from baseline to discharge, assessed with the dual-task (i.e., verbal and arithmetic) Gait Velocity Test (GVT) and the Trail Making Test Part A (TMT-A). Changes in the Mini Mental State Examination (MMSE) test and verbal fluency ability were also measured after the intervention period. The physical exercise program provided significant benefits over usual care. At discharge, the exercise group showed a mean increase of 0.1 m/s (95% confidence interval CI, 0.07, 0.13; p < 0.001) in the verbal GVT and 0.1 m/s (95% CI, 0.08, 0.13; p < 0.001) in the arithmetic GVT over usual care group. There was an apparent improvement in the intervention group also in the TMT-A score (-31.1 seconds; 95% CI, -49.5, -12.7 versus -3.13 seconds; 95% CI, -16.3, 10.2 in the control group; p < 0.001) and the MMSE score (2.10 points; 95% CI, 1.75, 2.46 versus 0.27 points; 95% CI, -0.08, 0.63; p < 0.001). Significant benefits were also observed in the exercise group for the verbal fluency test (mean 2.16 words; 95% CI, 1.56, 2.74; p < 0.001) over the usual care group. The main limitations of the study were patients' difficulty in completing all the tasks at both hospital admission and discharge (e.g., 25% of older patients were unable to complete the arithmetic GVT, and 47% could not complete the TMT-A), and only old patients with relatively good functional capacity at preadmission (i.e., Barthel Index score ≥60 points) were included in the study.
An individualized, multicomponent exercise training program may be an effective therapy for improving cognitive function (i.e., executive function and verbal fluency domains) in very old patients during acute hospitalization. These findings support the need for a shift from the traditional (bedrest-based) hospitalization to one that recognizes the important role of maintaining functional capacity and cognitive function in older adults, key components of intrinsic capacity.

We aimed to test the predictive ability and to compare the predictive ability of the USEM to SRS, SORT and ASA in a prospective sample.
A Prospective cohort of >65-year-old patients undergoing urgent ...abdominal surgery in a Hospital. Models calibration and discrimination were evaluated using the receiver operating characteristics curves and the Hosmer-Lemeshow test.
A total of 500 patients with a median age of 78 years were included. The AUROC in the validation cohort was 0.824. The USEM overestimated mortality (Test Hosmer-Lemeshow p < 0.001), after recalibration the USEM provided an accurate prediction of postoperative mortality.
After the recalibration, the USEM had good discriminant power to estimate the risk of mortality in elderly patients after urgent abdominal surgery.

Purpose
To perform a post hoc analysis of patient-incurred costs in a randomized controlled clinical trial comparing prostatic artery embolization (PAE) and transurethral resection of the prostate ...(TURP).
Materials and Methods
Patients older than 60 years with indication of TURP were randomized to PAE or TURP procedure. After intervention and hospital discharge, patients were follow-up during 12 months The associated patient costs were categorized according to the study period: pre-intervention, intervention, hospitalization, and follow-up. Several items for both groups were analyzed within each study period.
Results
The mean total costs per patient were lower for PAE (€ 3,192.87) than for TURP (€ 3,974.57), with this difference of € 781.70 being significant
(p
= 0.026). For most evaluated items, the mean costs were significantly higher for TURP. No significant differences were observed in the mean costs of PAE (€ 1,468.00) and TURP (€ 1,684.25) procedures (
p
= 0.061). However, the histopathology analysis, recovery room stay, and intraoperative laboratory analysis increased the interventional costs for TURP (€ 1,999.70) compared with PAE (€ 1,468.00) (
p
< 0.001). No cost differences were observed between PAE (€ 725.26) and TURP (€ 556.22) during the 12 months of follow-up (
p
= 0.605). None of patients required a repeat intervention during the study period.
Conclusions
Considering the short-term follow-up, PAE was associated with significantly lower costs compared with TURP. Future investigations in the context of routine clinical practice should be aimed at comparing the long-term effectiveness of both procedures and determining their cost-effectiveness.

Background
Physical exercise is an effective strategy for preserving functional capacity and improving the symptoms of frailty in older adults. In addition to functional gains, exercise is considered ...to be a cornerstone for enhancing cognitive function in frail older adults with cognitive impairment and dementia. We assessed the effects of the Vivifrail exercise intervention for functional capacity, cognition, and well‐being status in community‐dwelling older adults.
Methods
In a multicentre randomized controlled trial conducted in three tertiary hospitals in Spain, a total of 188 older patients with mild cognitive impairment or mild dementia (aged >75 years) were randomly assigned to an exercise intervention (n = 88) or a usual‐care, control (n = 100) group. The intervention was based on the Vivifrail tailored multicomponent exercise programme, which included resistance, balance, flexibility (3 days/week), and gait‐retraining exercises (5 days/week) and was performed for three consecutive months (http://vivifrail.com). The usual‐care group received habitual outpatient care. The main endpoint was change in functional capacity from baseline to 1 and 3 months, assessed with the Short Physical Performance Battery (SPPB). Secondary endpoints were changes in cognitive function and handgrip strength after 1 and 3 months, and well‐being status, falls, hospital admission rate, visits to the emergency department, and mortality after 3 months.
Results
The Vivifrail exercise programme provided significant benefits in functional capacity over usual‐care. The mean adherence to the exercise sessions was 79% in the first month and 68% in the following 2 months. The intervention group showed a mean increase (over the control group) of 0.86 points on the SPPB scale (95% confidence interval CI 0.32, 1.41 points; P < 0.01) after 1 month of intervention and 1.40 points (95% CI 0.82, 1.98 points; P < 0.001) after 3 months. Participants in the usual‐care group showed no significant benefit in functional capacity (mean change of −0.17 points 95% CI −0.54, 0.19 points after 1 month and −0.33 points 95% CI −0.70, 0.04 points after 3 months), whereas the exercise intervention reversed this trend (0.69 points 95% CI 0.29, 1.09 points after 1 month and 1.07 points 95% CI 0.63, 1.51 points after 3 months). Exercise group also obtained significant benefits in cognitive function, muscle function, and depression after 3 months over control group (P < 0.05). No between‐group differences were obtained in other secondary endpoints (P > 0.05).
Conclusions
The Vivifrail exercise training programme is an effective and safe therapy for improving functional capacity in community‐dwelling frail/prefrail older patients with mild cognitive impairment or mild dementia and also seems to have beneficial effect on cognition, muscle function, and mood status.
Objective
This study aimed to determine the predictive accuracy of the modified clinical prognostic tool Criteria for Screening and Triaging to Appropriate aLternative care (CriSTAL) to predict ...30-day and 90-day mortality in older patients undergoing urgent abdominal surgery.
Background
Anticipating the mid-term mortality of older patients undergoing urgent surgery is complex and flawed with uncertainty.
Methods
A prospective study of consecutive ≥ 65 years old presenting at the emergency department who subsequently underwent urgent abdominal surgery. The modified CriSTAL score was calculated in the sample using the FRAIL scale instead of the Clinical Frailty Scale. Discrimination (area under the receiver-operating characteristic (AUROC)) and model calibration were used to test the predictive accuracy of the modified CriSTAL score for death within 30-day mortality as the primary outcome.
Results
A total of 500 patients (median age 78 years) were enrolled. The observed 30-day and 90-day mortality rate were 11.6% and 13.6%. The modified CriSTAL tool AUROC curve to predict 30-day and 90-day mortality was 0.78 and 0.77. The model was well calibrated according to the Hosmer-Lemeshow test (
p
: 0.302) and the calibration plots to predict 30-day and 90-day mortality.
Conclusions
The modified CriSTAL tool (with FRAIL scale as frailty instrument) had good discriminant power and was well calibrated to predict 30-day and 90-day mortality in elderly patients undergoing urgent abdominal surgery. The modified CriSTAL tool is an easy preoperative tool that could assist in the prognosis of postoperative outcomes and decision-making discussions with patients before for urgent abdominal surgery.
an increasing number of elderly patients undergo urgent abdominal surgery and this population has a higher risk of mortality. The main objective of the study was to identify mortality-associated ...factors in elderly patients undergoing abdominal surgery and to design a mortality scoring tool, the Urgent Surgery Elderly Mortality risk score (the USEM score).
this was a retrospective study using a prospective database. Patients > 65 years old that underwent urgent abdominal surgery were included. Risk factors for 30-day mortality were identified using multivariate regression analysis and weights assigned using the odds ratios (OR). A mortality score was derived from the aggregate of weighted scores. Model calibration and discrimination were judged using the receiver operating characteristics curves and the Hosmer-Lemeshow test.
in the present study, 4,255 patients were included with an 8.5% mortality rate. The risk factors significantly associated with mortality were American Society of Anesthesiologists (ASA) score, age, preoperative diagnosis (OR: 37.82 for intestinal ischemia, OR: 5.01 for colorectal perforation, OR: 6.73 for intestinal obstruction), surgical wound classification and open or laparoscopic surgery. A risk score was devised from these data for the estimation of the probability of survival in each patient. The area under the ROC curve (AUROC) for this score was 0.84 (95% CI: 0.82-0.86) and the AUROC correct was 0.83 (0.81-0.85).
a simple score that uses five clinical variables predicts 30-day mortality. This model can assist surgeons in the initial evaluation of an elderly patient undergoing urgent abdominal surgery.
Background
A classic consequence of short‐term bed rest in older adults is the significant loss in skeletal muscle mass and muscle strength that underlies the accelerated physical performance ...deficits. Structured exercise programmes applied during acute hospitalization can prevent muscle function deterioration.
Methods
A single‐blind randomized clinical trial conducted in an acute care for elders unit in a tertiary public hospital in Navarre (Spain). Three hundred seventy hospitalized patients 56.5% female patients; mean age (standard deviation) 87.3 (4.9) years were randomly allocated to an exercise intervention (n = 185) or a control (n = 185) group (usual care). The intervention consisted of a multicomponent exercise training programme performed during 5–7 consecutive days (2 sessions/day). The usual‐care group received habitual hospital care, which included physical rehabilitation when needed. The main endpoints were change in maximal dynamic strength (i.e. leg‐press, chest‐press, and knee extension exercises) and maximal isometric knee extensors and hip flexors strength from baseline to discharge. Changes in muscle power output at submaximal and maximal loads were also measured after the intervention.
Results
The physical exercise programme provided significant benefits over usual care. At discharge, the exercise group showed a mean increase of 19.6 kg 95% confidence interval (CI), 16.0, 23.2; P < 0.001 on the one‐repetition maximum (1RM) in the leg‐press exercise, 5.7 kg (95% CI, 4.7, 6.8; P < 0.001) on the 1RM in the chest‐press exercise, and 9.4 kg (95% CI, 7.3, 11.5; P < 0.001) on the 1RM in the knee extension exercise over usual‐care group. There were improvements in the intervention group also in the isometric maximal knee extension strength 14.8 Newtons (N); 95% CI, 11.2, 18.5 vs. −7.8 N; 95% CI, −11.0, −3.5 in the control group; P < 0.001 and the hip flexion strength (13.6 N; 95% CI, 10.7, 16.5 vs. −7.2 N; 95% CI, −10.1, −4.3; P < 0.001). Significant benefits were also observed in the exercise group for the muscle power output at submaximal loads (i.e. 30% 1RM, 45% 1RM, 60% 1RM, and 75% 1RM; all P < 0.001) over usual‐care group.
Conclusions
An individualized, multicomponent exercise training programme, with special emphasis on muscle power training, proved to be an effective therapy for improving muscle power output of lower limbs at submaximal loads and maximal muscle strength in older patients during acute hospitalization.
Major trauma is a leading cause of death. Due to the difficulties to keep a registry of these cases, few studies include all subjects, because they exclude out-of-hospital deaths. The purpose of this ...work was to compare the epidemiological profiles of out-of-hospital deaths, in-hospital deaths, and survivors over a 10-year period (2010-2019) of patients who had been treated by Navarre´s Health Service (Spain).
Retrospective longitudinal cohort study using data of patients injured by an external physical force of any intentionality and with a New Injury Severity Score above 15. Hangings, drownings, burns, and chokings were excluded. Intergroup differences of demographic and clinical variables were analysed using the Kruskal Wallis test, chi-squared test, or Fisher´s exact test.
Data from 2,610 patients were analysed; 624 died out-of-hospital, 439 in-hospital, and 1,547 survived. Trauma incidences remained moderately stable over the 10-year period analysed, with a slight decrease in out-of-hospital deaths and a slight increase in in-hospital deaths. Patients of the out-of-hospital deaths group were younger (50.9 years) in comparison to in-hospital deaths and survivors. Death victims were predominantly male in all study groups. Intergroup differences regarding prior comorbidities and predominant type of injury were observed.
There are significant differences among the three study groups. More than half of the deaths occur out-of-hospital and the causative mechanisms differ in each of them. Thus, when designing strategies, preventive measures were considered for each group on a case-by-case basis.
Purpose
Frailty, polypharmacy, and underprescription are considered a major matter of concern in nursing homes, but the possible relationships between them are not well known. The aim is to examine ...the possible association between medication underprescription, polypharmacy, and frailty in older people living in nursing homes.
Methods
A cross-sectional analysis from a concurrent cohort study, including 110 subjects ≥ 65 years living in two nursing homes. Four frailty scales were applied; polypharmacy was defined as ≥ 5 medications and underprescription was measured with Screening Tool to Alert to Right Treatment (START) criteria. Logistic regression models were performed to assess the associations.
Results
The mean age was 86.3 years (SD 7.3) and 71.8% were female. 73.6% of subjects took ≥ 5 chronic medications and 60.9% met one or more START criteria. The non-frail participants took more medications than the frail subjects according to the imputated frailty Fried criteria (8.1 vs 6.7,
p
= 0.042) and the FRAIL-NH scale (7.8 vs 6.8,
p
= 0.026). Multivariate analyses did not find an association between frailty and polypharmacy. Frail participants according to the Fried criteria met a higher number of START criteria (1.9 vs 1.0,
p
= 0.017), and had a higher prevalence of underprescription (87.5 vs 50.0%), reaching the limit of statistical significance in multivariate analysis.
Conclusion
The positive association found in previous studies between frailty and polypharmacy cannot be extrapolated to institutionalized populations. There is a trend towards higher rates of underprescription in frail subjects. Underprescription in frail older adults should be redefined and new strategies to measure it should be developed.
The MDS-PSP criteria have shown high sensitivity for the PSP diagnosis, but do not discriminate the phenotype diversity. Our purpose was to search for anatomopathological differences among PSP ...phenotypes resulting from the application of the MDS-PSP criteria comparing with the previous ones.
Thirty-four PSP cases from a single brain bank were retrospectively classified according to the criteria used by Respondek et al. in 2014 and the PSP-MDS criteria at 3 years (MDS-3y), 6 years (MDS-6y) and at the last clinical evaluation before death (MDS-last). Semiquantitative measurement of total, cortical and subcortical tau load was compared. For comparative analysis, PSP-Richardson syndrome and PSP postural instability were grouped (PSP-RS/PI) as well as the PSP atypical cortical phenotypes (PSP-Cx).
Applying the Respondek's criteria, PSP phenotypes were distributed as follow: 55.9% PSP-RS/PI, 26.5% PSP-Cx, 11.8% PSP-Parkinsonism (PSP-P), and 5.9% PSP-Cerebellum. PSP-RS/PI and PSP-Cx had a higher total tau load than PSP-P; PSP-Cx showed a higher cortical tau load than PSP-RS/PI and PSP-P; and PSP-RS/PI had a higher subcortical tau load than PSP-P. Applying the MDS-3y, MDS-6y and MDS-last criteria; the PSP-RS/PI group increased (67.6, 70.6 and 70.6% respectively) whereas the PSP-Cx group decreased (8.8, and 8.8 and 11.8%). Then, only differences in total and subcortical tau burden between PSP-RS/PI and PSP-P were observed.
After the retrospective application of the new MDS-PSP criteria, total and subcortical tau load is higher in PSP-RS/PI than in PSP-P whereas no other differences in tau load between phenotypes were found, as a consequence of the loss of phenotypic diversity.
