Labrafil M2125-CS is a non-ionic surfactant component widely used for improving the solubilization of poor water-soluble drugs and as component of lipid-based nanosystem formulation. The aim of this research work was to evaluate in depth the stability of lipid-based nanosystems when exposed at several experimental conditions, such as temperature- and pH-variations, and during a specific storage process—lyophilization. Dynamic light scattering was the main analysis carried out during this research work for investigating eventual physico-chemical variations of nanosystem properties after different storage phases. We demonstrated that many of prepared formulations were able to maintain almost unchanged mean size and polydispersity index values, resisting acid and basic pH or high and low temperature, as well as the freeze-drying process. Finally, the results showed that there are no univocal experimental conditions suitable for the storage of all formulation types, but each sample requires customized conditions.

Summary In this longitudinal study, with a follow-up of 8 years, multidimensional prognostic index (MPI), a product of the comprehensive geriatric assessment, significantly predicted the onset of fractures in older people affected by knee osteoarthritis. Purpose Frailty may be associated with higher fracture risk, but limited research has been carried out using a multidimensional approach to frailty assessment and diagnosis. The present research aimed to investigate whether the MPI, based on comprehensive geriatric assessment (CGA), is associated with the risk of fractures in the Osteoarthritis Initiative (OAI) study. Methods Community-dwellers affected by knee OA or at high risk for this condition were followed-up for 8 years. A standardized CGA including information on functional, nutritional, mood, comorbidity, medication, quality of life, and co-habitation status was used to calculate the MPI. Fractures were diagnosed using self-reported information. Cox’s regression analysis was carried out and results are reported as hazard ratios (HRs), with their 95% confidence intervals (CIs), adjusted for potential confounders. Results The sample consisted of 4024 individuals (mean age 61.0 years, females = 59.0%). People with incident fractures had a significant higher MPI baseline value than those without (0.42 ± 0.18 vs. 0.40 ± 0.17). After adjusting for several potential confounders, people with an MPI over 0.66 (HR = 1.49; 95%CI: 1.11–2.00) experienced a higher risk of fractures. An increase in 0.10 point in MPI score corresponded to an increase in fracture risk of 4% (HR = 1.04; 95%CI: 1.008–1.07). Higher MPI values were also associated with a higher risk of non-vertebral clinical fractures. Conclusion Higher MPI values at baseline were associated with an increased risk of fractures, reinforcing the importance of CGA in predicting fractures in older people affected by knee OA.

Pre-operative delirium may cause delay in surgical intervention in older patients hospitalized for hip fracture. Also it has been associated with higher risk of post-surgical complications and worst functional outcomes. Aim of this retrospective cohort study was to evaluate whether the multidimensional prognostic index (MPI) at hospital admission was associated with pre-operative delirium in older individuals with hip fracture who are deemed to require surgical intervention. Consecutive older patients (≥ 65 years) with hip fracture underwent a comprehensive geriatric assessment to calculate the MPI at hospital admission. According to previously established cut-offs, MPI was expressed in three grades, i.e. MPI-1 (low-risk), MPI-2 (moderate-risk) and MPI-3 (high risk of mortality). Pre-operative delirium was assessed using the four ‘A’s Test. Out of 244 older patients who underwent surgery for hip fracture, 104 subjects (43%) received a diagnosis of delirium. Overall, the incidence of delirium before surgery was significantly higher in patients with more severe MPI score at admission. Higher MPI grade (MPI-3) was independently associated with higher risk of pre-operative delirium (OR 2.45, CI 1.21–4.96). Therefore, the MPI at hospital admission might help in early identification of older patients with hip fracture at risk for pre-operative delirium.

Neste artigo propomos problematizar o dispositivo da maternidade, bem como algumas normativas maquinadas para tentar definir uma categoria nomeada "mulher", a partir de nossas pesquisas com os corpos que gestam e as maternidades, bem como dos textos publicados no livro Sangrias (2019). Tratamos a maternidade enquanto dispositivo biopolítico, tecnologia que busca produzir e manter certos modos de vida em coerência com forjada lógica sexo-gênero, bem como a heterossexualidade compulsória, que serve a uma determinada sociedade capitalista neoliberal. Diante a esse cenário, apostamos em epistemologias transbordantes feministas de vida e de pesquisa que nos convocam a uma fluidez e transposição das fronteiras das categorias identitárias como forma de produzir escapes e outras configurações sobre gestações e maternagens, outras formas de vida. Apostamos na política ciborgue, proposta por Donna Haraway como tática de produção de outros e transitórios corpos, moventes e constituídos pautados no desejo ético, nos prazeres e na alegria como tática potente de (re)existir.

A novel effervescent buffered solution of 70 mg alendronate (ALN-EX) was developed to improve upper gastrointestinal (GI) tolerability over alendronate tablets (ALN-T). Whether a better GI tolerability can improve persistence remains to be determined. This study evaluated persistence and reasons for discontinuation in patients treated with ALN-EX compared to a historical cohort on ALN-T.

Cardiac remuscularization has been the stated goal of the field of regenerative cardiology since its inception. Along with the refreshment of lost and dysfunctional cardiac muscle cells, the field of cell therapy has expanded in scope encompassing also the potential of the injected cells as cardioprotective and cardio-reparative agents for cardiovascular diseases. The latter has been the result of the findings that cell therapies so far tested in clinical trials exert their beneficial effects through paracrine mechanisms acting on the endogenous myocardial reparative/regenerative potential. The endogenous regenerative potential of the adult heart is still highly debated. While it has been widely accepted that adult cardiomyocytes (CMs) are renewed throughout life either in response to wear and tear and after injury, the rate and origin of this phenomenon are yet to be clarified. The adult heart harbors resident cardiac/stem progenitor cells (CSCs/CPCs), whose discovery and characterization were initially sufficient to explain CM renewal in response to physiological and pathological stresses, when also considering that adult CMs are terminally differentiated cells. The role of CSCs in CM formation in the adult heart has been however questioned by some recent genetic fate map studies, which have been proved to have serious limitations. Nevertheless, uncontested evidence shows that clonal CSCs are effective transplantable regenerative agents either for their direct myogenic differentiation and for their paracrine effects in the allogeneic setting. In particular, the paracrine potential of CSCs has been the focus of the recent investigation, whereby CSC-derived exosomes appear to harbor relevant regenerative and reparative signals underlying the beneficial effects of CSC transplantation. This review focuses on recent advances in our knowledge about the biological role of exosomes in heart tissue homeostasis and repair with the idea to use them as tools for new therapeutic biotechnologies for “cell-less” effective cardiac regeneration approaches.

This systematic review on sexualities and gender covers 80 articles, published by the Interamerican Journal of Psychology until the year 2019. The sample, selected and classified into three themes by the thematic analysis method, shows a productivity raise in this regard upon the 1990s. Ever since, debates on sexual differences and roles amidst the sample have declined while productions on gender have grown, according to the first theme. On the second, it was possible to infer that such an increase had significant collaboration from the health areas, highlighting yet the importance of some health, sexual and (non-)reproductive health intervention strategies. The contribution of family arrangements and motherhood was pointed out in the third theme along with the lack of studies that are not only centered in cis-heteronormativity. Therefore, we outline our snippet from a genealogical perspective in Latin American Psychology, highlighting the importance to think of and to implement strategies that are closer to the psychosocial, ethical and cultural realities of the region.

Cardiovascular disease (CVD) remains the leading cause of death in Western countries. Post-myocardial infarction heart failure can be considered a degenerative disease where myocyte loss outweighs any regenerative potential. In this scenario, regenerative biology and tissue engineering can provide effective solutions to repair the infarcted failing heart. The main strategies involve the use of stem and progenitor cells to regenerate/repair lost and dysfunctional tissue, administrated as a suspension or encapsulated in specific delivery systems. Several studies demonstrated that effectiveness of direct injection of cardiac stem cells (CSCs) is limited in humans by the hostile cardiac microenvironment and poor cell engraftment; therefore, the use of injectable hydrogel or pre-formed patches have been strongly advocated to obtain a better integration between delivered stem cells and host myocardial tissue. Several approaches were used to refine these types of constructs, trying to obtain an optimized functional scaffold. Despite the promising features of these stem cells’ delivery systems, few have reached the clinical practice. In this review, we summarize the advantages, and the novelty but also the current limitations of engineered patches and injectable hydrogels for tissue regenerative purposes, offering a perspective of how we believe tissue engineering should evolve to obtain the optimal delivery system applicable to the everyday clinical scenario.

Glycyrrhiza glabra L. is a native plant of Central and South-Western Asia that is also diffused in the Mediterranean area and contains several bioactive compounds such as: flavonoids, sterols, triterpene and saponins. Glycyrrhizin, containing glycyrrhizic and glycyrrhizinic acids has anti-inflammatory and antiallergic effects that are similar to corticosteroids. Ammonium glycyrrhizinate is a derivative salt of glycyrrhizic acid with similar anti-inflammatory activity that cannot pass through the skin due to its physicochemical properties and molecular weight. Although several nanoformulations, such as ethosomes, are designed to provide a systemic effect through a topical application, there are different limitations to the distribution inside the blood stream. For this reason, ultradeformable liposomes, or transfersomes, are selected to improve the topical delivery of drugs and allow the distribution of payloads in the blood stream because they pass intact through the stratum corneum epidermis barrier, due to the presence of sodium cholate, aqueous cutaneous gradient, and the rapid penetration of transfersomes by cutaneous tight junctions, thus allowing the systemic delivery of different therapeutic cargo in non-occlusive conditions. The aim of this work was the synthesis and physicochemical characterization of the ammonium glycyrrhizinate-loaded ultradeformable liposomes, the evaluation of drug release and permeation through stratum corneum and epidermis barrier. The in vivo anti-inflammatory effect of ammonium glycyrrhizinate-loaded ultradeformable liposomes was tested on human healthy volunteers. The results demonstrated that the ammonium glycyrrhizinate-loaded ultradeformable liposomes decreased the skin inflammation on the human volunteers and the resulting nanoformulations can be used as a potential topical drug delivery system for anti-inflammatory therapy. ☆Parts of these results were presented as a poster communication at the Recent Developments in Pharmaceutical Analysis 2019 (RDPA 2019), Chieti, Italy.

Inadequate therapies and clinical methods for overcoming multidrug-resistant cancer constitute the major barrier for cancer treatment. Also, early detection of this disease is fundamental and new nanotechnologies emerge with clear relevance. Considering their distinctive chemical and physical properties, plasmonic nanoparticles have been proposed and are regarded as promising carriers for cancer treatment. Gold nanoparticles (AuNPs) are the most studied plasmonic nanoparticles because of their special optical and electronic properties. Depending on size and shape, AuNPs are able to perform, simultaneously, several therapeutic functions, including photothermal therapy (PTT), photodynamic therapy (PDT), and imaging. The synergistic effect between PTT/PDT and chemotherapeutic drugs, to cooperatively suppress cancer cells, has also been studied, wherein rod-shaped AuNPs has been pointed out as suitable theranostic NP. This demonstrates their ability to integrate multiple functions in a single system. However, their performance is highly dependent on several experimental parameters including size, aspect ratio, surface modification, and morphology. All these parameters strongly affect both the physical and biological processes involved. This review focuses on AuNRs properties, their multiple applications, and the trends for the integration of theranostic applications. Also described are the difficulties imposed to an effective in vivo biodistribution and pharmacokinetic behavior. Current research and preclinical and clinical investigation will be addressed.

To investigate the short- and long-term effects of different combinations of dietary instructions on cariogenic food intake and salivary cariogenic bacteria (Streptococcus mutans [SM] and Lactobacillus [LB]).In this randomised 2-arm parallel study, 75 6-year-old subjects were assigned to repeated (group A; 19M/19F) or isolated (group B; 17M/20F) verbal and/or written dietary advice (VWDA), with foods classified by cariogenic potential. Both groups underwent a baseline salivary test for SM/LB, kept a monthly food diary, and attended 4 weekly visits (T1-T4). At T1-T2; group A only received VDA. At T3, both groups received VWDA. At T4, participants handed in their food diaries and underwent another salivary test. After 1 year (T5), subjects were recalled for weekly food diary monitoring and salivary testing. Relative risk (RR) of high-to-low SM/LB density was calculated at T4 and T5.Comparing groups A and B, VDA determined an increase in the intake of weakly cariogenic food (p0.05) and a decrease in that of intermediately cariogenic food (p0.05). After VWDA, a statistically significant increase in intake of weakly cariogenic food and a statistically significant decrease in the RR of high-density SM/LB colonies occurred in both groups. At T5, group A showed less intake of highly cariogenic food than did group B (p = 0.05) and persistent, although non-significant, reduction in the RR of high-density SM/LB colonies.Reinforcement measures on behavioural changes towards a noncariogenic diet not only help maintain long-lasting, healthier eating habits, but also decrease the cariogenic bacterial load in the short term, which tends to persist over time.

BACKGROUND The role of bisphosphonates (BPs) in the management of patients with hypercalciuria (HC) associated with osteoporosis is still uncertain. The aim of the study was to evaluate the effect of alendronate and indapamide alone or in combination on bone mineral density (BMD) and 24-h urinary calcium excretion (24-CaU) in post-menopausal women with HC and low BMD. METHODS A total of 77 post-menopausal women with HC (24-CaU > 4 mg/kg/day) and low BMD [T-score < -2.0 at lumbar spine (LS), femoral neck (FN) or total hip (TH)] from two centres of Northern Italy were randomized to receive indapamide 2.5 mg daily alone (24 patients, IND group), alendronate 70 mg weekly alone (27 patients, ALN group) or the combination therapy (26 patients, ALN + IND group). Throughout the study, all subjects received daily calcium supplements, depending on their dietary intake, to maintain a daily input of 1000 mg. Patients were instructed to increase water intake up to 2000 mL daily. The percentage and absolute changes of BMD at LS, FN and TH, and the variation of 24-CaU from baseline at 1 year were the primary outcomes. Serum calcium, phosphate, parathyroid hormone and bone alkaline phosphatase were also measured. RESULTS Overall 67 women completed the study and were included in the final analysis. Patients in the three groups were similar with regard to baseline characteristics. BMD did not significantly change from baseline after 1 year of treatment with indapamide (LS: +1 +/- 3.1%; FN: -0.3 +/- 3.5%; TH: -0.4 +/- 3.1%), while it showed a significant increase from baseline in the other two groups (ALN; LS: +5.8 +/- 4.2%, P < 0.001; FN: +3.9 +/- 7.9%, P = 0.018; TH: +2 +/- 3.6%, P = 0.006) (ALN + IND; LS: +8.2 +/- 5.3%, P < 0.001; FN: +4.9 +/- 6.7%, P = 0.007; TH: +2.9 +/- 4.2%, P = 0.004). Patients in the combination group showed a significantly higher increase of BMD at LS compared to ALN (P = 0.04). After 1 year, 24-CaU values significantly decreased from baseline in all groups (IND, 239 +/- 78 versus 364 +/- 44, P < 0.001) (ALN, 279 +/- 68 versus 379 +/- 79, P < 0.001) (ALN + IND, 191 +/- 68 versus 390 +/- 55, P < 0.001). The mean percentage decrease of 24-CaU in ALN + IND group (-50%) was significantly greater compared to ALN (-24%, P < 0.001) and IND (-35%, P = 0.012). CONCLUSIONS These results show a benefit, in terms of BMD improvement and 24-CaU reduction, associated with BPs' therapy in combination with indapamide in HC associated with osteoporosis. The combination therapy demonstrated a reduction of 24-CaU and an increase in LS BMD superior to that observed with alendronate alone. Our results support a new potential approach with BPs associated with thiazide diuretics or indapamide in the management of post-menopausal women with HC and associated bone loss. Studies on the larger sample size are needed to demonstrate the efficacy on the fracture outcome.

Whether elderly patients with asymptomatic or minimally symptomatic primary hyperparathyroidism (PHPT) should be treated or not is still under debate. Several literature reports have shown improvements in terms of bone density and physical and mental well-being after surgical resolution of PHPT. Here, we present the case of a 93-year-old hypertensive woman, who had suffered for one year from cognitive impairment, accompanied during the last month by behavioral alterations (and polyuria and polydipsia), which resulted in sopor leading to hospitalization. A CT brain scan evidenced cortical atrophy and cerebrovascular disease, and biochemical analyses were remarkable for hypercalcemia (11.4-12.6 mg/dL, corrected for albumin levels) associated with increased parathormone levels (95.4-100.6 pg/mL). A diagnosis of PHPT was established. Densitometry evaluation of radius showed osteopenia. Withdrawal of psycho-therapy drugs and thiazidic, together with i.v. saline hydration and loop diuretics, significantly improved the patient's mental state and resolved behavioral alterations. As the patient and her relatives refused the surgical option, and the clinical situation improved after medical normalization of calcium levels, PHPT was managed conservatively, and calcium levels were maintained within the normal range through i.v. administration of zoledronate at 8-week intervals. Our case highlights the importance of considering hypercalcemia as the cause of onset of behavioral alterations and worsening of mental condition in elderly patients with cognitive decline. Therapy with bisphosphonates in patients with PHPT who are unfit for or refuse surgery seems advisable, but needs further study.

This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Societa Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture.

Introduction The recent improvement in the resolution of dual-energy X-ray absorptiometry (DXA) images enables most vertebral levels to be seen adequately and thus DXA may be a worthwhile alternative to radiologic morphometry for the identification of vertebral fractures (VF). In this multicenter study, we have derived reference data for vertebral heights and their ratios in Italian women using morphometric X-ray absorptiometry (MXA). Methods DXA scans were acquired in 1254 consecutive pre- and postmenopausal women, (mean age 63.7 ± 11.3, range 26–88 yrs), referred to six osteoporosis centers. MXA analysis of these images was performed by the same operator measuring vertebral heights and height ratios from L4 to T4. We calculated measures of central tendency and dispersion of vertebral heights and vertebral ratios using different approaches (mean and standard deviation as well as median and interquartile range of raw data, mean and standard deviation of trimmed data using an iterative algorithm, and mean and standard deviation of not fractured vertebrae). Results Independently of the approach that we used, all the measures of central tendency were similar, while significant differences were found when compared with reference ranges in other populations. The vertebral heights of our sample at every vertebral level were significantly smaller than both Rea population and the Lunar reference values, even after normalization. Splitting data according to age groups, there was a decrease in the vertebral heights and ratios between the younger and older women. Conclusions This study demonstrates that reference data for MXA should be population specific and age matched.

Idiopathic hypercalciuria (IHC) is defined as a 24-hour urinary calcium excretion that exceeds 4 mg/kg/day, regardless of gender and in absence of systemic diseases or pharmacological treatments that may cause normocalcemic hypercalciuria (eg sarcoidosis, normocalcemic primary hyperparathyroidism, vitamin D intoxication, hyperthyroidism). Patients with IHC and nephrolithiasis often present increased bone turnover, decreased bone mineral density (BMD) and increased susceptibility to fragility fractures. Although the pathogenesis of IHC seems complex and multifactorial, recent evidences suggest that cells involved in bone resorption may play a critical role in the chain of events leading to the excessive urinary calcium excretion. Therefore, it has been proposed that bisphosphonates, potent inhibitors of bone resorption, may have beneficial effects in hypercalciuric patients with low BMD. This manuscript reports recent findings regarding the role of bone tissue in the pathogenesis of IHC, and supports the use of bisphosphonates in such conditions. It also reviews the literature on the effects of bisphosphonates in subjects with osteoporosis-associated IHC.

Changes in bone mineral density and bone strength following treatment with zoledronic acid (ZOL) were measured by quantitative computed analysis (QCT) or dual-energy X-ray absorptiometry (DXA). ZOL treatment increased spine and hip BMD vs placebo, assessed by QCT and DXA. Changes in trabecular bone resulted in increased bone strength.To investigate bone mineral density (BMD) changes in trabecular and cortical bone, estimated by quantitative computed analysis (QCT) or dual-energy X-ray absorptiometry (DXA), and whether zoledronic acid 5 mg (ZOL) affects bone strength.In 233 women from a randomized, controlled trial of once-yearly ZOL, lumbar spine, total hip, femoral neck, and trochanter were assessed by DXA and QCT (baseline, Month 36). Mean percentage changes from baseline and between-treatment differences (ZOL vs placebo, t-test) were evaluated.Mean between-treatment differences for lumbar spine BMD were significant by DXA (7.0%, p0.01) and QCT (5.7%, p0.0001). Between-treatment differences were significant for trabecular spine (p = 0.0017) [non-parametric test], trabecular trochanter (10.7%, p0.0001), total hip (10.8%, p0.0001), and compressive strength indices at femoral neck (8.6%, p = 0.0001), and trochanter (14.1%, p0.0001).Once-yearly ZOL increased hip and spine BMD vs placebo, assessed by QCT vs DXA. Changes in trabecular bone resulted in increased indices of compressive strength.

Background and aims: Few studies have investigated predictors for hospital readmission after hip fracture repair. Methods: In a prospective cohort study we evaluated factors associated with early (within 3 months) and late (between 3–12 months), single and multiple hospital readmission in 236 hip-fractured older adults admitted to an orthopedic unit. Baseline patient characteristics and hospital course (functional and cognitive status, comorbidity, type of fracture, time to surgery, in-hospital stay, complications) were recorded. Hospital readmission over 12 months and ICD-9 principal diagnosis were ascertained from administrative sources. Functional status at the end of the rehabilitation program was assessed by telephone interviews. Results: Seventy-one patients (30.1%) were readmitted to hospital within twelve months of discharge and 22 (9.3%) had two or more readmission. The total number of readmissions was 105, 43 (41%) occurred in the first three months. The most common readmission causes were cardiac, infectious and cerebrovascular; surgical complication accounted for 5.7%. Patients with a single readmission, like those with multiple readmissions, were sicker (CIRS-CIsubscore 4.0±1.8 vs 3.2±1.6, p=0.010) and more functionally impaired at the end of rehabilitation (2 months’ Katz index 2.1±2 vs 2.9±2.3, p=0.007) than controls. In a multiple logistic regression model, comorbidity and functional status at the end of rehabilitation were the only factors associated with the risk of readmission. Conclusions: Subjects at high risk of readmission can be reliably assessed, since few significant variables were associated with rehospitalization. Subgroups of patients with an elevated risk of rehospitalization after hip fracture may be the target for strategies to reduce the burden of excessive hospital use and improve overall outcomes.

Hip fracture (HF) is a major health care problem in the Western world, associated with significant morbidity, mortality and loss of function. Its incidence is expected to increase as the population ages. The authors discuss the role of a coordinated multidisciplinary team in the management of patients during hospital stay, at discharge and during rehabilitation. Orthogeriatric care should not just be viewed as a multidisciplinary activity, but as a radical alternative to the traditional model of care, an alternative based on all those strategies in which evidence shows an improvement in outcomes in the fractured elderly. Therefore, key points of the care are early surgery, immediate mobilization, prevention and management of delirium, pain and malnutrition, as well as an integrated and multidisciplinary approach. Comprehensive geriatric assessment is useful in identifying frail elderly and in providing information that is essential in formulating clinical recommendations and making care plans. In each hospital, the orthogeriatric unit should represent a center of excellence for treating elderly patients with major fractures. However, when an orthogeriatric project is implemented, it is essential that detailed data about the case-mix of patients, process of care and outcomes are collected, to compare the results with historical data and to be able to participate in audit processes.

Background and aims: The study investigates one-year mortality risk associated with hip fracture in elderly people, and pre-fracture characteristics and events occurring during the acute phase which may represent significant predictors for acute and long-term mortality. Methods: The study is a prospective cohort study of 252 patients aged 70 and older, consecutively admitted with hip fracture to the Division of Orthopedic Surgery of the Galliera Hospital of Genoa, Italy. At admission, each subject received a standardized diagnostic evaluation, including demographic variables, biochemical markers of nutritional status and basic medical, functional and cognitive assessment. Patients were followed by telephone interviews at three months, six months and one year after fracture. The relationship between mortality and the risk factors recorded was assessed using logistic regression models. Results: 248 patients were eligible. Cumulative mortality was 4.8% during hospital stay, and 12.5% at 3, 18.9% at 6 and 24% at 12 months. The risk factors significantly associated with mortality were: sex, Acute Physiology Score (APS), comorbidity, functional and cognitive status, and albumin levels. In multivariate models, albumin below 3 g/dL remained the only significant predictor of in-hospital mortality (OR 6,8, 95% CI 1.56-29,7, p
