RESUMO
BACKGROUND: Several techniques are available to identify, among patients with mild cognitive impairment (MCI), those at risk of conversion to Alzheimer dementia (CAD). However, simple cost-effective methods to assess the risk are not available yet. METHODS: This retrospective study included 143 MCI outpatients (76.6±5.2 years, 46.8% women). Baseline variables were common neuropsychological tests (including Mini Mental State Examination-MMSE and Montreal Cognitive Assessment-MoCA), brain CT and 18F-fluorodeoxyglucose (FDG)-PET. Outcome variable was CAD after 1 year. RESULTS: At follow-up, 31 (21.7%) patients had CAD. In multivariable analysis (OR, 95% CI), female sex (4.7, 1.6-14.0), MoCA-executive component <3 (6.3, 2.1-19.2), left medial temporal atrophy (MTA) ≥3 (5.4, 1.9-15.7) and FDG-PET suggesting CAD (5.4, 1.9-15.7) were associated with CAD (area under ROC curve 0.873). Without FDG-PET, MMSE score <28 remained associated with CAD (6.0, 2.2-16.9). As first step (before FDG-PET execution), we counted 1 point for MMSE <28, executive MoCA <3 and left MTA ≥3. With 2-3 points CAD probability was high (75%) and with 0 points it was low (6.5%). Thus, FDG-PET (second step) might be performed only in patients with 1 point (probability 19.7%, 42.7% of patients). Among them, 35% had a positive FDG-PET, suggesting high risk. Overall, 28.0% of patients were considered at high risk (specificity 83.9%, sensitivity 71.0%, accuracy 81.1%). CONCLUSION: With a 2-step procedure, less than half of MCI patients might undergo FDG-PET and nearly a quarter of our patients was found to be at high CAD risk, including almost three quarters of future CADs.

Ageing of the global population represents a challenge for national healthcare systems and healthcare professionals, including medico-legal experts, who assess personal damage in an increasing number of older people. Personal damage evaluation in older people is complex, and the scarcity of evidence is hindering the development of formal guidelines on the subject. The main objectives of the first multidisciplinary Consensus Conference on Medico-Legal Assessment of Personal Damage in Older People were to increase knowledge on the subject and establish standard procedures in this field. The conference, organized according to the guidelines issued by the Italian National Institute of Health (ISS), was held in Bologna (Italy) on June 8, 2019 with the support of national scientific societies, professional organizations, and stakeholders. The Scientific Technical Committee prepared 16 questions on 4 thematic areas: (1) differences in injury outcomes in older people compared to younger people and their relevance in personal damage assessment; (2) pre-existing status reconstruction and evaluation; (3) medico-legal examination procedures; (4) multidimensional assessment and scales. The Scientific Secretariat reviewed relevant literature and documents, rated their quality, and summarized evidence. During conference plenary public sessions, 4 pairs of experts reported on each thematic area. After the last session, a multidisciplinary Jury Panel (15 members) drafted the consensus statements. The present report describes Conference methods and results, including a summary of evidence supporting each statement, and areas requiring further investigation. The methodological recommendations issued during the Conference may be useful in several contexts of damage assessment, or to other medico-legal evaluation fields.

BACKGROUND: Hip fractures (HF) are a major issue worldwide. We aimed at evaluating the practices in delivering care to patients with HF among several Italian Orthogeriatric centers. METHODS: The study took place from February 2016 to July 2018. Seven performance indicators (pre-surgical cognitive assessment, surgery performed ≤ 48 h from fracture, removal of urinary catheter/absence of delirium/start of physiotherapy on the first post-operative day, prescription of bone protection at discharge, and discharge toward rehabilitation) were collected. RESULTS: The 14 participating hospitals totally recruited 3.017 patients. Patients were old (median age 86 years; Inter Quartile Range [IQR] 80-90), mostly females (77%). Nearly 55% of them were already impaired in mobility and about 10% were nursing home residents. Median time-to-surgery was 41 h (IQR 23-62). Models of care greatly varied among centers, only 49.3% of patients being co-managed by geriatricians and orthopedics. There was high variability across centers in four indicators ("pre-surgical cognitive assessment", "bone protection prescription", "use of urinary catheter" and "start of physiotherapy"), moderate in two indicators ("surgery performed ≤ 48 h from fracture" and "discharge toward rehabilitation" and low in one ("absence of delirium on day following surgery"). Comparison with international studies suggests very different ways of providing care to HF Italian patients. CONCLUSIONS: The study results suggest high inter-center variability in the key-performance indicators, and different approaches in providing care to our HF patients in comparison to other countries. A National debate on the topic is required in Italy to harmonize practices of orthogeriatric care.

BACKGROUND: Delirium is a disorder in awareness, attention and cognition. Pathophysiologically it is a response to stress. Postoperative delirium (POD) is a usual complication in aged patients following hip fracture surgery. Neuroinflammation is an important factor linked with the progress of POD. Though there are no efficient cures for delirium the endocannabinoid system may have a role in neuropsychiatric disorders. OBJECTIVE: Therefore, we examined the effects of co-ultramicronized PEALut (co-ultraPEALut) in the LPS murine model of delirium and in elderly hip fractured patients. METHODS: In the preclinical study, mice were injected intraperitoneally (i.p.) with Escherichia coli LPS (10 mg/kg). Co-ultraPEALut (1 mg/kg o.s.) was administered 1h before LPS injection or 1h and 6h after LPS injection or 1h before LPS injection and 1h and 6h after LPS. In the clinical study, the effects of Glialia® (co-ultramicronized 700 mg PEA + 70 mg luteolin) administration was evaluated in elderly hip fractured patients with an interventional, randomized, single-blind, monocentric study. RESULTS: Administration of co-ultraPEALut to LPS-challenged mice ameliorated cognitive dysfunctions and locomotor activity; moreover, it reduced inflammation and apoptosis, while stimulating antioxidant response and limiting the loss of neurotrophins. In the clinical study, the results obtained demonstrated that administration of Glialia® to these surgical patients prevented the onset of POD and attenuated symptom intensity and their duration. CONCLUSION: Therefore, the results obtained enhanced the idea that co-ultraPEALut may be a potential treatment to control cognitive impairment and the inflammatory and oxidative processes associated with delirium.

BACKGROUND: In older people, hip fractures often lead to disability and death. We evaluated handgrip strength, an objective measure of physical function for bedridden patients, as a predictor of walking recovery in the year after fracture surgery. METHODS: This multicenter prospective cohort study included 504 patients, aged 70 years or more, who were admitted to the hospital for hip fracture surgery and were formerly able to walk independently. A multidimensional geriatric evaluation that included a physical examination, Short Portable Mental Status Questionnaire, Geriatric Depression Scale, Charlson Index, Basic Activities of Daily Living, and grip strength was administered at the time of admission. Follow-ups were performed every 3 months for 1 year after surgery to assess functional status and survival. The walking recovery probability was evaluated using multivariable logistic regression models. RESULTS: The mean age of the participants was 85.3 ± 5.5 years, and 76.1% of the participants were women. The mean grip strength was greater in men (ß: 6.6 ± 0.62, P < .001) and was directly related to the Short Portable Mental Status Questionnaire results (P < .001), Basic Activities of Daily Living results (P < .001), serum vitamin D levels (P = .03), and time before surgery (P < .001), whereas it was inversely related to age (P < .001), Geriatric Depression Scale score (P < .001), and Charlson Index (P < .001). After adjusting for confounders, the grip strength was directly associated with the probability of both incident and persistent walking recovery (odds ratio highest tertile vs lowest tertile, 2.84, confidence interval, 1.76-4.59 and 2.79, confidence interval, 1.35-5.79, respectively). CONCLUSIONS: In older patients with hip fractures, early grip strength evaluation might provide important prognostic information regarding the patient's future functional trajectory.

BACKGROUND: Hip fractures represent a major challenge for physicians as well as society as a whole. Both poor functional status and delay to surgery are well known risk factors for negative outcomes. We hypothesized that the timing of the operation is more important for frail older people than older people without functional limitations before fracture. METHODS: We performed a prospective multicenter cohort study on 806 consecutive patients, 75 years of age or older, admitted with a fragility hip fracture to three hospitals in the Emilia-Romagna Region (Italy). All three hospitals had a comanaged care model, and the patients were under the shared responsibility of an orthopedic surgeon and a geriatrician. RESULTS: Functional status assessed as instrumental activities of daily living was an important predictor of survival after 1 year from fracture. After adjusting for confounders, the hazard ratios per 1 point score of increase from 0 to 8 was 1.30 (95% confidence interval 1.19-1.42, p = .000). Time to surgery increased 1-year mortality in patients with a low instrumental activities of daily living score (hazard ratios per day of surgical delay 1.14, 95% confidence interval 1.06-1.22, p < .001) and intermediate instrumental activities of daily living score (hazard ratios 1.21, 95% confidence interval 1.09-1.34, p < .001) but was an insignificant risk factor in functionally independent patients (hazard ratios 1.05 95% confidence interval 0.79-1.41, p = .706). CONCLUSIONS: Surgery delay is an independent factor for mortality in older patients after hip fracture but only for the frail older people with prefracture functional impairment. If our results are confirmed, a more intensive approach should be adopted for older people with hip fractures who have disabilities.

OBJECTIVE: To compare the pathways of care and clinical results for patients admitted for hip fracture (HF) in 3 orthogeriatric co-managed care centers in order to estimate the effect of system factors on mortality and functional outcome. DESIGN: Prospective inception multicenter cohort study. SETTING: Three tertiary Hospitals. PARTICIPANTS: 806 patients consecutively admitted with HF. MEASUREMENTS: 1-Year mortality, the loss of 1 or more functional abilities in activities of daily living (ADLs), and the recovery/maintenance of independent ambulation at 6 months from the fracture. RESULTS: On the whole sample, 71.1% of patients survived 1 year from the fracture. In one hospital the risk of 1-year mortality was significantly higher even after adjusting for age, sex, comorbidity, prefracture functional status and cognitive impairment (odd ratio (OR) 1.56, 95% confidence interval (CI) 1.15-2.18, p=0.01). This was principally explained by a longer time to surgery (5.2 days ± 3.2 vs 2.7 ± 2.3 and 2.7 ± 2.2, p<0.001). The three hospitals also differed in the rate of subjects losing the ability in ADLs after 6 months from the fracture (54.2%, 61%, 43.5%, p=0.016), while no statistical differences were found in the recovery of independent ambulation. On the basis of multivariate models, a lower access to post-acute rehabilitation could account for lower outcome in functional status. CONCLUSIONS: This study suggests that system factors such as time to surgery and rehabilitation resources can affect functional recovery and 1-year mortality in orthogeriatric units and they could explain different outcomes when comparing care models.
