RESUMO

INTRODUCTION: Nephrotoxicity is a significant side effect of thoracic transplantation. Many lung transplant patients will require subsequent renal transplantation (KAL). Recently, simultaneous lung/kidney transplants (SLuK) have become an attractive option for patients with end-stage renal disease at the time of lung transplantation. This article explores SLuK outcomes compared to conventional KAL, as well as outcomes among KAL patients against those were KAL listed but never transplanted. MATERIALS AND METHODS: The United Network for Organ Sharing/the Organ Procurement and Transportation Network database was used to identify SLuK patients (n = 74), KAL transplants (n = 456), and patients who were listed for KAL but were never transplanted (n = 626). Significance was determined by chi2, Wilcoxon rank sum test, or independent t-tests. Death-censored graft survival for subgroups was estimated using Kaplan-Meier with log-rank for significance. Analyses were completed using SPSS Statistics 28. RESULTS: The SLuK cohort was older (P = 0.04), more likely diabetic (P < 0.001), and had shorter life expectancies (P < 0.001) than KAL patients. Of those SLuK transplants within 5 y, 84% of patients were alive 1 y post transplant and 82% were alive 3 y post-transplant (compared to 74.6% and 60.3% of overall SLuK). Patients who did undergo KAL were younger and had a lower body mass index (both P < 0.001) compared to those who did not. Those who received a kidney had increased survival times compared to WL patients (P < 0.001). CONCLUSIONS: Conventional KAL transplants are still favorable for average lung recipients. However, recent improvements have made SLuK an option for patients with renal dysfunction. Those patients who were able to receive KAL transplants were better surgical candidates than those who remained on the waitlist.

RESUMO

INTRODUCTION: Data on frailty frequency are heterogeneous and mostly based on cross-sectional studies. Little is known about frailty development and progression over time. Our aim was to conduct a systematic analysis of frailty prevalence and incidence in a large cohort of older adults and to evaluate the association with incident disability, in order to tackle the current paucity and fragmentation of longitudinal data on frailty. METHODS: As secondary analysis of the Italian Longitudinal Study on Aging (ILSA) population-based cohort (n = 5,632, 65-84), frailty status was operationalized according to Fried criteria (n = 2,457). Weighted prevalence and incidence rates were calculated at each ILSA wave (T0 1992-1993, T1 1995-1996, T2 2000-2001). The association with incident disability in Activities of Daily Living (ADL) or Instrumental Activities of Daily Living (IADL) was investigated through Cox proportional hazard models, controlling for possible confounders. RESULTS: Prevalence of frailty and pre-frailty at baseline (mean age 71.6 years; women 58.9%) were 4.0% (95% confidence interval [CI]: 3.4-4.6) and 44.6% (95% CI: 43.1-46.1), respectively. Incidence rates per 1,000 person-years for the T0-T1 interval were 7.3 (95% CI: 5.2-9.3) for frailty and 83.7 (95% CI: 73.6-93.8) for pre-frailty. Prevalence and incidence of frailty, and to a lesser degree of pre-frailty, were overall higher for women and increased with age, yet no increasing trend with advancing age was detected for pre-frailty incidence. Frailty incidence rates were significantly higher among pre-frail than non-frail individuals at follow-up entry. After full adjustment, being frail markedly increased the risk of incident disability in ADL (hazard ratio [HR] 3.58, 95% CI: 1.97-6.52) and IADL (HR 2.56, 95% CI: 1.58-4.16) over a 4-year period. DISCUSSION/CONCLUSION: According to our findings, frailty is common among older people and is a strong and independent predictor of disability. Further research on factors and characteristics related to frailty progression, and especially remission, over time is crucial to calibrate effective public health preventive measures.

RESUMO

BACKGROUND AND AIM: Benefits of oral anticoagulants (OAC) in atrial fibrillation (AF) patients with moderate-to-high risk of stroke are independent of AF pattern. We evaluated whether AF clinical subtype influenced OAC use in a representative sample of the Italian older population. METHODS: A cross-sectional examination of all subjects aged 65 + years from three general practices in northern, central, and southern Italy started in 2016. A double-screening procedure was followed by clinical and ECG confirmation. Patients were categorized as having paroxysmal, persistent, or permanent AF. OAC use was evaluated in confirmed AF patients. RESULTS: The sample included 6016 subjects. Excluding 235 non-eligible, participation was 78.3%, which left 4528 participants (mean age 74.5 ± 6.8 years, 47.2% men). Overall, 319 AF cases were identified: 43.0% had paroxysmal, 21.3% persistent, and 35.7% permanent AF. Frequency of OAC therapy was 91.2% in permanent, 85.3% in persistent, and only 43.0% in paroxysmal AF (P < 0.001). In multivariate analysis, controlled for baseline variables and risk scales, persistent and permanent AF were associated with a significant increase in the likelihood of receiving OAC compared with paroxysmal AF (P < 0.001). This was confirmed for permanent AF also in multivariate analyses considering separately vitamin K antagonists or direct-acting oral anticoagulants (OR, 4.37, 95% CI, 2.43-7.85; and 1.92, 95% CI, 1.07-3.42, respectively) and for persistent AF and direct-acting oral anticoagulants (OR, 4.33, 95% CI, 2.30-8.15). CONCLUSIONS: In a population-based survey, AF pattern was an independent predictor of OAC treatment. Paroxysmal AF is still perceived as carrying a lower risk of vascular events.

RESUMO

G-protein coupled receptor (GPCR) kinase 2 (GRK2) is upregulated in heart failure (HF) patients and mouse models of cardiac disease. GRK2 is a regulator of ß-adrenergic receptors (ßARs), a GPCR involved in ionotropic and chronotropic responses. We and others have recently reported GRK2 to be localized in the mitochondria, although its function in the mitochondria and/or metabolism remain not clearly defined. We hypothesized that upregulation of GRK2 reduced mitochondrial respiratory function and responses to ßAR activation. Utilizing isolated mouse primary adult cardiomyocytes (ACMs), we investigated the role of glucose, palmitate, ketone bodies, and BCAAs in mediating cell survival. Our results showed that myocyte upregulation of GRK2 promotes palmitate-induced cell death. Isotopologue labeling and mass spectrometry showed that the upregulation of GRK2 reduces ß-hydroxybutyryl CoA generation. Next, using isoproterenol (ISO), a non-selective ßAR-agonist, we determined mitochondrial function in mouse and human primary ACMs. Upregulation of GRK2 impaired ISO-mediated mitochondrial functional responses, which we propose is important for metabolic adaptations in pathological conditions. Increased cardiac levels of GRK2 reduced fatty acid-specific catabolic pathways and impaired ISO-stimulated mitochondrial function. Our data support the notion that GRK2 participates in bioenergetic remodeling and may be an important avenue for the development of novel pharmacological strategies in HF.

RESUMO

AIMS: To estimate prevalence of atrial fibrillation (AF) in a representative sample of the Italian elderly population, projecting figures for Italy and the European Union. METHODS AND RESULTS: A cross-sectional examination of all subjects aged 65+ years from three general practices in Northern, Central, and Southern Italy started in 2016. Participants were administered a systematic and an opportunistic screening, followed by clinical and electrocardiogram confirmation. The study sample included 6016 subjects. Excluding 235 non-eligible, among the remaining 5781 participation was 78.3%, which left 4528 participants (mean age 74.5 ± 6.8 years, 47.2% men). Prevalence of AF was 7.3% [95% confidence intervals (CI) 6.6-8.1], higher in men and with advancing age (6.6% from systematic plus 0.7% from opportunistic screening). Using prevalence figures, Italian elderly having AF in 2016 were estimated at ∼1 081 000 (95% CI 786 000-1 482 000). Considering stable prevalence, this number will increase by 75% to ∼1 892 000 in 2060 (95% CI 1 378 000-2 579 000). European Union elderly having AF in 2016 were estimated at ∼7 617 000 (95% CI 5 530 000-10 460 000), increasing by 89% to ∼14 401 000 in 2060 (95% CI 10 489 000-19 647 000). In 2016, subjects aged 80+ years represented 53.5% of cases in Italy and 51.2% in the European Union; in 2060, 69.6% and 65.2%, respectively. CONCLUSIONS: Our findings indicate a high burden of AF in coming decades, especially among the oldest-old, who carry the higher AF-related risk of stroke and medical complications.

RESUMO

INTRODUCTION: Frailty is a critical intermediate status of the aging process including physical, cognitive, and psychosocial domains/phenotypes. We operationalized a new biopsychosocial frailty (BF) construct, estimating its impact on the risk of incident dementia and its subtypes. METHODS: In 2171 older individuals from the population-based Italian Longitudinal Study on Aging (ILSA), we identified by latent class procedures the BF construct as the physical frail status plus at least one of the two items of the 30-item Geriatric Depression Scale impaired (items 3/10). RESULTS: Over a 3.5-year follow-up, participants with BF showed an increased risk of overall dementia (hazard ratio [HR]: 2.16, 95% confidence interval [CI]:1.07-4.37), particularly vascular dementia (VaD) (HR: 3.21, 95% CI: 1.05-9.75). Similarly, over a 7-year follow-up, an increased risk of overall dementia (HR: 1.84, 95% CI: 1.06-3.20), particularly VaD (HR: 2.53, 95% CI: 1.08-5.91), was also observed. DISCUSSION: In a large cohort of Italian older individuals without cognitive impairment at baseline, a BF model was a short- and long-term predictor of overall dementia, particularly VaD.

RESUMO

OBJECTIVE: Cognitive frailty is a condition recently defined by operationalized criteria describing the simultaneous presence of physical frailty and mild cognitive impairment (MCI). Two subtypes for this clinical construct have been proposed: "potentially reversible" cognitive frailty (physical frailty plus MCI) and "reversible" cognitive frailty (physical frailty plus pre-MCI subjective cognitive decline). Here the prevalence of a potentially reversible cognitive frailty model was estimated. It was also evaluated if introducing a diagnosis of MCI in older subjects with physical frailty could have an additive role on the risk of dementia, disability, and all-cause mortality in comparison with frailty state or MCI condition alone, with analyses separately performed for inflammatory state. METHODS: In 2,373 individuals from the population-based Italian Longitudinal Study on Aging with a 3.5-year-follow-up, we operationally categorized older individuals without dementia into four groups: non-frail/non-MCI, non-frail/MCI, frail/non-MCI, and frail/MCI. RESULTS: The prevalence of potentially reversible cognitive frailty was 1%, increasing with age and more represented in women than in men, and all groups were associated with significant increased incident rate ratios of dementia, disability, and mortality. A significant difference in rates of disability has been found between the MCI and non-MCI groups (contrasts of adjusted predictions: 0.461; 95% confidence interval: 0.187-0.735) in frail individuals with high inflammatory states (fibrinogen >339 mg/dL). CONCLUSION: In older individuals without dementia and with elevated inflammation, a potentially reversible cognitive frailty model could have a significant additional predictive effect on the risk of disability than the single conditions of frailty or MCI.

RESUMO

Any strategy to reduce stroke burden involves crucial inputs from individuals (risk reduction, rapid recognition and response to symptoms onset) which imply a certain level of stroke knowledge. Health-related applications (apps) have been identified as a novel platform for dissemination of health information to the public. Only few apps about stroke are currently available with scientifically valid information, none of them are available in Italian. We developed the first and only Italian stroke app, ICTUS3R. We also pilot tested ICTUS3R in terms of its usage during the first 12 months following release (October 30, 2014). ICTUS3R was developed in collaboration with communication experts, stroke leaders and web producers. ICTUS3R was pilot tested in terms of number and distribution of downloads. Data about 1 year usage were anonymously collected from ICTUS 3R release on October 30, 2014. ICTUS3R includes a stroke screening tool, information how to react in case of suspected stroke, and information about risk factors including personal stroke risk calculator. ICTUS 3R web site was visited 36,242 times. Mean session duration was over 2 min. The 48 % of downloads were by individuals aged 25-44 years, 12 % by individuals ≥55 years. ICTUS3R downloads were distributed across all the Italian provinces, in varying proportions. The 4.3 % of downloads were done outside Italy. ICTUS3R can be an important contribution to stroke management and prevention, it proved to be well received for dissemination of stroke information among Italians. Its use could contribute to reduce stroke burden in Italy.

RESUMO

BACKGROUND AND PURPOSE: Differences in stroke care and outcomes reported in Europe may reflect different degrees of implementation of evidence-based interventions. We evaluated strategies for implementing research evidence into stroke care in 10 European countries. METHODS: A questionnaire was developed and administered through face-to-face interviews with key informants. Implementation strategies were investigated considering 3 levels (macro, meso, and micro, eg, policy, organization, patients/professionals) identified by the framing analysis, and different settings (primary, hospital, and specialist) of stroke care. Similarities and differences among countries were evaluated using the categorical principal components analysis. RESULTS: Implementation methods reported by ≥7 countries included nonmandatory policies, public financial incentives, continuing professional education, distribution of educational material, educational meetings and campaigns, guidelines, opinion leaders', and stroke patients associations' activities. Audits were present in 6 countries at national level; national and regional regulations in 4 countries. Private financial incentives, reminders, and educational outreach visits were reported only in 2 countries. At national level, the first principal component of categorical principal components analysis separated England, France, Scotland, and Sweden, all with positive object scores, from the other countries. Belgium and Lithuania obtained the lowest scores. At regional level, England, France, Germany, Italy, and Sweden had positive scores in the first principal component, whereas Belgium, Lithuania, Poland, and Scotland showed negative scores. Spain was in an intermediate position. CONCLUSIONS: We developed a novel method to assess different domains of implementation in stroke care. Clear variations were observed among European countries. The new tool may be used elsewhere for future contributions.

RESUMO

Stroke knowledge improves public behavior in terms of prevention, symptom recognition, and timely response. Contemporary data on stroke awareness in the Italian general population are lacking. This study surveyed public knowledge of risk factors, warning signs, and proper reactions to stroke among Italian adults. A population-based telephone survey was carried out in a sample of 1,000 residents aged ≥18 years in May-June 2010. The questionnaire included close-ended questions focused on stroke symptoms, risk factors, and treatment options. We examined the prevalence and distribution of stroke knowledge in the community and generated multivariable logistic regression models. Among the 1,000 participants (481 men, mean age 48.8 ± 17.2), only the 55.8 % correctly identified the brain as the affected organ in stroke. The most common risk factor for stroke identified by respondents was hypertension (67.6 %), the most common warning sign was hemiparesis (68.7 %), the 43.5 % could list >1 warning sign. Multivariate analyses indicate that education and previous stroke experience are the only independent predictors of stroke knowledge. Only 26.2 % reported to know about the availability of t-PA treatment. An ambulance would be called by 59 % of respondents in the event of a stroke. Respondents with a high level of education are more likely to call an ambulance in case of stroke. This study provides the first comprehensive data describing stroke knowledge among Italian adults: the general level is suboptimal and is associated only with education and previous family experience of stroke. Public education could potentially improve treatment and prevention.

RESUMO

BACKGROUND: Lay involvement in implementation of research evidence into practice may include using research findings to guide individual care, as well as involvement in research processes and policy development. Little is known about the conditions required for such involvement. AIM: To assess stroke survivors' research awareness, use of research evidence in their own care and readiness to be involved in research processes. METHODS: Cross sectional survey of stroke survivors participating in population-based stroke registers in six European centres. RESULTS: The response rate was 74% (481/647). Reasons for participation in register research included responding to clinician request (56%) and to 'give something back' (19%); however, 20% were unaware that they were participating in a stroke register. Research awareness was generally low: 57% did not know the purpose of the register they had been recruited to; 73% reported not having received results from the register they took part in; 60% did not know about any research on stroke care. Few participants (7.6%) used research evidence during their consultations with a doctor. The 34% of participants who were interested in being involved in research were younger, more highly educated and already research aware. CONCLUSIONS: Across Europe, stroke survivors already participating in research appear ill informed about stroke research. Researchers, healthcare professionals and patient associations need to improve how research results are communicated to patient populations and research participants, and to raise awareness of the relationship between research evidence and increased quality of care.

RESUMO

A 58-year-old woman had an incidentally found complex right renal artery aneurysm (RAA) during a clinical work-up for diverticulitis. The aneurysm measured 2.5 cm in diameter and was located at the right renal artery bifurcation. She was hospitalized and underwent hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and autotransplantation into the right iliac fossa. The same incision was used to remove the kidney from the retroperitoneum as was used to transplant into the right lower quadrant. She tolerated the procedure well. Her postoperative course was uncomplicated. Hand-assisted laparoscopic nephrectomy with ex vivo repair of a complicated RAA and autotransplantation is feasible and safe.

RESUMO

BACKGROUND AND AIMS: Quality monitoring has great relevance in stroke care. The Project "How to guarantee adherence to effective interventions in stroke care" aimed to estimate adherence to acute-phase guidelines in stroke care in Italy. METHODS: A prospective observational study was performed in 27 hospitals of 13 Italian Regions. Adherence to 15 process indicators was evaluated, comparing also stroke units (SU) with conventional wards. An overall score of care, defined as the sum of achieved indicators, was calculated. A multilevel hierarchical model described performance at patient, hospital and regional level. RESULTS: Overall, 484 consecutive stroke patients (mean age, 73.4 years; 52.7 % males) were included. Total score ranged from 2 to 15 (mean 8.5 ± 2.4). SU patients were more often evaluated with the National Institutes of Health Stroke Scale (NIHSS) within 24 h, had more frequently an assessment of pre- and post-stroke disability, and a CT scan the same or the day after admission. Regional-hospital- and patient-level variability explained, respectively, 25, 34, and 41 % of total score variance. In multivariate models, patients >80 years vs. younger showed a change in total score of -0.45 (95 % CI -0.79 to -0.12), and those with NIHSS ≥14 vs. ≤5 of -0.92 (95 % CI -1.53 to -0.30). A negative change means a worse adjusted average adherence to process indicators. SU admission increased total score of 1.55 (95 % CI 0.52-2.58). CONCLUSIONS: Our data confirm the need of quality monitoring in stroke care. Although SU patients showed a better adherence to quality indicators, overall compliance was unsatisfactory.

RESUMO

INTRODUCTION: This study identifies the effect of individual donor and recipient characteristics on graft survival in living-donor kidney transplantation (LDKT) using a recently described novel measure, kidney life years (KLYs). MATERIALS AND METHODS: The Organ Procurement and Transplantation Network/United Network for Organ Sharing database was used to identify first-time kidney-only LDKT recipients between 1987 and 2020 who did not experience death with a functioning graft (DWFG) and were not missing relevant information (n = 87,290). Patient characteristics were evaluated using Cox and multiple regression analyses, with the dependent variable being KLYs. An equation for expected KLYs based on patient characteristics was created using regression coefficients. The equation was validated using bootstrapped Pearson correlations and then applied to the DWFG group for comparison. RESULTS: Based on statistical significance from Cox and multiple linear regression analyses, 9 of the original 18 variables were selected for inclusion in the equation. Variables with notable impact included HLA match points (0.021 KLYs; 95% CI: [0.019,0.024]; P ≤ .001), Donor Age (-0.030 KLYs; 95% CI: [-0.035,-0.025]; P ≤ .001), and Donor African American Ethnicity (-2.356 KLYs; 95% CI: [-2.552,-2.159]; P ≤ .001). Equation validation was supported, given a negative correlation (r = -0.071; P ≤ .001) between expected KLY change and observed graft failure. Expected KLY change was found to be greater in those who eventually DWFG when compared with all other LDKTs (t = -5.735, P ≤ .001). CONCLUSIONS: Increasing HLA match points may be more beneficial for graft longevity than minimizing donor age in comparisons using realistic between-donor differences. Additionally, greater average expected KLYs in those who ultimately DWFG may illustrate an opportunity for improved donor-recipient matching.

RESUMO

Sorafenib was shown in clinical trial to enhance survival in hepatocellular carcinoma (HCC) patients, but with minimal tumor shrinkage. To correlate several indices of HCC growth at various drug concentrations, HCC cells were grown in various low concentrations of two multikinase inhibitors, regorafenib (Stivarga) and sorafenib (Nexavar) and their effects were examined on alpha-fetoprotein (AFP), cell growth, migration, and invasion. In two AFP positive human HCC cell lines, AFP was inhibited at 0.1-1 µM drug concentrations. Cell migration and invasion were also inhibited at similar low drug concentrations. However, 10-fold higher drug concentrations were required to inhibit cell growth in both AFP positive and negative cells. To investigate this concentration discrepancy of effects, cells were then grown for prolonged times and sub-cultured in low drug concentrations and then their growth was re-tested. The growth in these drug-exposed cells was found to be slower than cells without prior drug exposure and they were also more sensitive to subsequent drug challenge. Evidence was also found for changes in cell signaling pathways in these slow-growth cells. Low multikinase inhibitor concentrations thus modulate several aspects of HCC cell biology.

RESUMO

BACKGROUND: The need for stroke care is escalating with an ageing population, yet methods to estimate the delivery of effective care across countries are not standardised or robust. Associations between quality and intensity of care and stroke outcomes are often assumed but have not been clearly demonstrated. OBJECTIVE: To examine variations in acute care processes across six European populations and investigate associations between the delivery of care and survival. METHODS: Data were obtained from population-based stroke registers of six centres in France, Lithuania, UK, Spain, Poland and Italy between 2004 and 2006 with follow-up for 1 year. Variations in the delivery of care (stroke unit, multidisciplinary team and acute drug treatments) were analysed adjusting for case mix and sociodemographic factors using logistic regression methods. Unadjusted and adjusted survival probabilities were estimated and stratified by levels of Organised Care Index. RESULTS: Of 1918 patients with a first-ever stroke registered, 30.7% spent more than 50% of their hospital stay in a stroke unit (13.9-65.4%) among centres with a stroke unit available. The percentage of patients assessed by a stroke physician varied between 7.1% and 96.6%. There were significant variations after adjustment for confounders, in the organisation of care across populations. Significantly higher probabilities of survival (p<0.01) were associated with increased organisational care. CONCLUSIONS: This European study demonstrated associations between delivery of care and stroke outcomes. The implementation of evidence-based interventions is suboptimal and understanding better ways to implement these interventions in different healthcare settings should be a priority for health systems.

RESUMO

We prospectively examined whether vascular factors are related to an increased incidence of Chronic Idiopathic Distal Symmetric Neuropathy (CI-DSN) in a non-diabetic elderly population. In 8 Italian municipalities, 2,512 men and women without both diabetes and CI-DSN at baseline are examined. Potential effect of vascular factors was estimated by regressing new onset CI-DSN on the occurrence of several vascular diseases and risk factors. Multivariate relative risks of CI-DSN were estimated by Cox proportional hazards models. After 3.8 (±2.4) years of follow-up, we documented 51 incident CI-DSN cases. At univariate analysis, age, comorbidity, waist circumference, leg length, peripheral artery disease, and coronary heart disease proved to increase the risk of developing CI-DSN. By multivariate analyses, only age (RR = 1.08; 95 % CI, 1.02-1.14), leg length (RR = 1.05; 95 % CI, 1.01-1.1) and peripheral artery disease (RR = 2.75; 95 % CI, 1.15-6.56) proved significant predictors of CI-DSN. Separate analyses by gender show that age is an independent predictor of CI-DSN both in men and in women, while PAD predicts the disease only in men, together with body height. Incidence of CI-DSN is higher in individuals carrying vascular conditions. In men, the presence at baseline of peripheral artery disease is associated with a threefold increase in the risk of developing CI-DSN. The incidence of neuropathy in non-diabetic individuals is associated with potentially modifiable vascular factors.

RESUMO

Access to effective acute stroke services is a crucial factor to reduce stroke-related death and disability, but is limited in different parts of Italy. Our study addresses this inequality across the Italian regions by examining the regional legislations issued to adopt and implement the State-Regional Council agreement 03/02/2005 as to the acute stroke management. All decrees and resolutions as to acute stroke were collected from each region and examined by the means of a check list including quantitative and qualitative characteristics, selected in accordance with the recommendations from the State-Regional Council document. Each completed check list was then sent to each regional reference person, who filled in the section on the implementation of the indications and compliance, with the collaboration of stroke specialists if necessary. The study was carried out from November 2009 to September 2010. The documents and information were collected from 19 regions. Our survey revealed disparities both in terms of number of decrees and resolutions and of topics covered by the regional legislations about stroke care. Most legislations lacked practical and economical details. This feedback from national and regional stroke regulations revealed a need of more concrete indications. Involvement of various stakeholders (legislators, consumers, providers) might possibly ensure that policies are actually adopted, implemented and maintained. Although considerable challenges are present to the development of standard and optimal stroke care more widely across Italian regions, the potential gains from such developments are substantial.

RESUMO

BACKGROUND: Frailty is a clinical syndrome generally associated with a greater risk for adverse outcomes such as falls, disability, institutionalization, and death. Cognition and dementia have already been considered as components of frailty, but the role of frailty as a possible determinant of dementia, Alzheimer's disease (AD), and vascular dementia (VaD) has been poorly investigated. We estimated the predictive role of frailty syndrome on incident dementia and its subtypes in a nondemented, Italian, older population. METHODS: We evaluated 2581 individuals recruited from the Italian Longitudinal Study on Aging sample population consisting of 5632 subjects aged 65 to 84 years and with a 3.9-year median follow-up. A phenotype of frailty according to a modified measurement of Cardiovascular Health Study criteria was operationalized. Dementia, AD, and VaD were classified using current published criteria. RESULTS: Over a 3.5-year follow-up, 65 of 2581 (2.5%) older subjects, 16 among 252 frail individuals (6.3%), of which 9 were affected by VaD (3.6%), developed overall dementia. In a proportional hazards model, frailty syndrome was associated with a significantly increased risk of overall dementia (adjusted hazard ratio: 1.85; 95% confidence interval: 1.01-3.40) and, in particular, VaD (adjusted hazard ratio: 2.68; 95% confidence interval: 1.16-7.17). The risk of AD or other types of dementia did not significantly change in frail individuals in comparison with subjects without frailty syndrome. CONCLUSION: In our large population-based sample, frailty syndrome was a short-term predictor of overall dementia and VaD.

RESUMO

Since 1995, rates of end-stage renal disease have risen dramatically in patients living with HIV infection. However, given the concern for higher rates of acute rejection in this patient population, the immunologic threat posed by HIV infection is a specter clinicians must continually confront. Living donor transplantation may negate this risk; this study aims to assess the benefit of living donor transplantation in this population and to ascertain the immunologic risk faced by patients who are HIV-infected. The 2021 UNOS database was queried, and all HIV-infected kidney transplant recipients since 1987 were identified. Recipients were stratified based on deceased (DDKT) vs living (LDKT) donor status. Overall survival, allograft survival, acute rejection, panel reactive antibody (PRA) percentage, and crossmatch positivity were compared between groups. One thousand two hundred twenty-six patients underwent DDKT, and 304 patients underwent LDKT. Living donor kidney transplantation demonstrated greater overall survival (P = .045) and graft survival (P < .001). However, no difference in acute rejection was noted between the cohorts, and no difference in overall or graft survival was evident based on PRA percentage. Crossmatch positive status did not negatively affect graft survival. Patients with HIV undergoing LDKT fared better than those undergoing DDKT. Nevertheless, patients at higher immunologic risk-elevated PRA% and crossmatch positivity-did not experience graft loss at a higher rate than patients at lower immunologic risk. These results were valid in both DDKT and LDKT cohorts. These findings suggest that infection with HIV does not overtly increase patients' immunologic risk, and concerns surrounding transplantation in this population may be overestimated.
