Abstract
We estimated the current size and dynamics of the wolf population in Tuscany and investigated the trends and demographic drivers of population changes. Estimates were obtained by two different approaches: (i) mixed-technique field monitoring (from 2014 to 2016) that found the minimum observed pack number and estimated population size, and (ii) an individual-based model (run by Vortex software v. 10.3.8.0) with demographic inputs derived from a local intensive study area and historic data on population size. Field monitoring showed a minimum population size of 558 wolves (SE = 12.005) in 2016, with a density of 2.74 individuals/100 km2. The population model described an increasing trend with an average annual rate of increase λ = 1.075 (SE = 0.014), an estimated population size of about 882 individuals (SE = 9.397) in 2016, and a density of 4.29 wolves/100 km2. Previously published estimates of wolf population were as low as 56.2% compared to our field monitoring estimation and 34.6% in comparison to our model estimation. We conducted sensitivity tests to analyze the key parameters driving population changes based on juvenile and adult mortality rates, female breeding success, and litter size. Mortality rates played a major role in determining intrinsic growth rate changes, with adult mortality accounting for 62.5% of the total variance explained by the four parameters. Juvenile mortality was responsible for 35.8% of the variance, while female breeding success and litter size had weak or negligible effects. We concluded that reliable estimates of population abundance and a deeper understanding of the role of different demographic parameters in determining population dynamics are crucial to define and carry out appropriate conservation and management strategies to address human-wildlife conflicts.

Abstract
Abstract
Background
Hospitals falls are an important challenge for healthcare systems. An early identification of patients at risk is critical, but no assessing tool has proven to be sufficiently predictive. This review aims at identifying factors associated with an increased risk of falls in hospitalized adults and at mapping them according to main international classification systems.
Methods
We carried out a systematic literature review and metanalysis to detect risk factors positively associated with the increase of falls in hospitals, searching litterature from January 2015 to March 2022. We included studies investigating falling risk factors in patients older than 16 years. Researchers independently assessed records’ eligibility and the methodological quality of included studies was assessed. When possible, data was processed using a random effects model and odds ratio (OR) with 95% confidence interval to quantify the effect. Risk factors were than classified according to ICF, ICD, and ATC classifications.
Results
We included 40 observational studies, enrolling 3,495,552 patients. Considering ICF-factors, mental and sensory functions-pain have a strong association with falls (OR = 3.311 and 2.149, respectively). ICD-factors associated with falls were mental and behavioural disorders (OR = 2.219), diseases of the nervous system (OR = 2.974), and symptoms, signs, and abnormal clinical and laboratory findings (OR = 2.665). Considering ATC-related factors, medications for alimentary tract and metabolism (OR = 1.978), and nervous system (OR = 1.779), showed a strong association with falls. Other factors were also associated with a moderately increased risk.
Conclusions
The comprehensive evidence-based assessment achieved with this meta-analysis alongside with the classification according to ICF, ICD and ATC systems provides a new standardized identification of the risk factors associated with an increase of falls in hospital.
Key messages
• Falls occurring in hospital are an important challenge for health care systems. Therefore the identification of risk factors associated to patients increased risk of fall is fundamental.
• The comprehensive evidence-based assessment achieved with this meta-analysis provides a new standardized identification of the risk factors associated with an increase of falls for hospital.

Abstract
An academic, anatomist, and Lombrosian psychiatrist active at the University of Parma in Italy at the end of the 19th century, Lorenzo Tenchini produced ceroplastic-like masks that are unique in the anatomical Western context. These were prepared from 1885 to 1893 with the aim of 'cataloguing' the behaviour of prison inmates and psychiatric patients based on their facial surface anatomy. Due to the lack of any reference to the procedure used to prepare the masks, studies were undertaken by our group using X-ray scans, infrared spectroscopy, bioptic sampling, and microscopy analysis of the mask constituents. Results showed that the masks were stratified structures including plaster, cotton gauze/human epidermis, and wax, leading to a fabrication procedure reminiscent of 'additive layer manufacturing'. Differences in the depths of these layers were observed in relation to the facial contours, suggesting an attempt to reproduce, at least partially, the three-dimensional features of the facial soft tissues. We conclude the Tenchini masks are the first historical antecedent of the experimental method for face reconstruction used in the early 2000s to test the feasibility of transferring a complete strip of face and scalp from a deceased donor to a living recipient, in preparation for a complete face transplant. In addition, the layering procedure adopted conceptually mimics that developed only in the late 20th century for computer-aided rapid prototyping, and recently applied to bioengineering with biomaterials for a number of human structures including parts of the skull and face. Finally, the masks are a relevant example of mixed ceroplastic-cutaneous preparations in the history of anatomical research for clinical purposes.

Abstract
Novel biomaterials are of paramount importance for bone regrowth. In this study, we investigated human adipose stem cells (hASCs) for osteogenic, osteoconductivity, and osteoinductivity effects of an innovative collagen/hydroxylapatite hybrid scaffold. In hASCs that were grown on this scaffold, osteogenic genes were analyzed for their expression profiles, together with adhesion and extracellular matrix genes. In hASC integrins, basement membrane constituents and collagens were up-regulated, together with cell proliferation. In addition, expression of osteopontin and activated focal adhesion kinase was studied at the protein level. Our in vitro data indicate that hASCs, together with hybrid biomaterial, is an important model of study to investigate in vitro bone induction.-Mazzoni, E., D'Agostino, A., Manfrini, M., Maniero, S., Puozzo, A., Bassi, E., Marsico, S., Fortini, C., Trevisiol, L., Patergnani, S., Tognon, M.

Abstract
INTRODUCTION Monitoring large carnivores is a central issue in conservation biology. The wolf (Canis lupus) is the most studied large carnivore in the world. After a massive decline and several local extinctions, mostly due to direct persecutions, wolves are now recolonizing many areas of their historical natural range. One of the main monitoring techniques is the howling survey, which is based on the wolves' tendency to use vocalisations to mark territory ownership in response to howls of unknown individuals. In most cases wolf howling sessions are useful for the localisation of the pack, but they provide only an aural estimation of the chorus size. We tested and present a new bioacoustic approach to estimate chorus size by recording wolves' replies and visualising choruses through spectrograms and spectral envelopes. To test the methodology, we compared: a) the values detected by visual inspections with the true chorus size to test for accuracy; b) the bioacoustic estimations of a sample of free-ranging wolves' replies developed by different operators to test for precision of the method; c) the aural field estimation of chorus size of a sample of free-ranging wolves' replies with the sonogram analysis of the same recordings to test for difference between methods. RESULTS Visual inspection of the chorus by spectrogram and spectrum proved to be useful in determining the number of concurrent voices in a wolf chorus. Estimations of chorus size were highly correlated with the number of wolves counted in a pack, and 92 % of 29 known chorus sizes were recognized by means of bioacoustic analysis. On the basis of spectrographic evidence, it was also possible to identify up to seven concurrent vocalisations in a chorus of nine wolves. Spectral analysis of 37 free ranging wolves' replies showed a high correlation between the chorus size estimations of the different operators (92.8 %), but a low correlation with the aural estimation (59.2 %). CONCLUSIONS Wolf howling monitoring technique could be improved by recording wolves' replies and by using bioacoustic tools such as spectrograms and spectral envelopes to determine the size of the wolf chorus. Compared with other monitoring techniques (i.e., genetic analysis), bioacoustic analysis requires widely available informatic tools (i.e., sound recording set of devices and sound analysis software) and a low budget. Information obtained by means of chorus analysis can also be combined with that provided by other techniques. Moreover, howls can be recorded and stored in audio file format with a good resolution (i.e. in "Wave" format), thus representing a useful tool for future listening and investigations, which can be countlessly employed without risks of time deterioration.

Abstract
Wolves (Canis lupus) in Italy represent a relict west European population. They are classified as vulnerable by IUCN, though have increased in number and expanded their range in recent decades. Here we use 17 years of monitoring data (from 1993 to 2010) collected in a mountainous region of central Italy (Arezzo, Tuscany) in an ecological niche-based model (MaxEnt) to characterize breeding sites (i.e. the areas where pups were raised) within home ranges, as detected from play-back responses. From a suite of variables related to topography, habitat and human disturbance we found that elevation and distance to protected areas were most important in explaining the locality of wolf responses. Rendezvous sites (family play-back response sites) typically occurred between 800 and 1200 m a.s.l., inside protected areas, and were usually located along mountain chains distant from human settlements and roads. In these areas human disturbance is low and the densities of ungulates are typically high. Over recent years, rendezvous sites have occurred closer to urban areas as the wolf population has continued to expand, despite the consequent human disturbance. This suggests that undisturbed landscapes may be reaching their carrying capacity for wolves. This, in turn, may lead to the potential for increased human-wolf interactions in future. Applying our model, both within and beyond the species' current range, we identify sites both within the current range and also further afield, that the species could occupy in future. Our work underlines the importance of the present protected areas network in facilitating the recolonisation by wolves. Our projections of suitability of sites for future establishment as the population continues to expand could inform planning to minimize future wolf-human conflicts.

Since poly(L-lactic acid) or PLLA is largely used in tissue engineering of human bones, and we are developing a reverse engineering program to prototype with biomaterials the vascular architecture of bones for their bioartificial reconstruction, both in humans and animal models, we have studied the effect of porous, flat and smooth PLLA scaffolds on the immunophenotype of in vitro grown, rat MSCs in the absence of any coating, co-polymeric enrichment, and differentiation stimuli. Similar to controls on plastic, we show that our PLLA scaffold does not modify the distribution of some surface markers in rat MSCs. In particular, the maintained expression of CD73 and CD90 on two different subpopulations (small and large cells) is consistent with their adhesion to the PLLA scaffold through specialized appendages, and to their prominent content in actin. In addition, our PLLA scaffold favours retention of the intermediate filament desmin, believed a putative marker of undifferentiated state. Finally, it preserves all rat MSCs morphotypes, and allows for their survival, adhesion to the substrate, and replication. Remarkably, a subpopulation of rat MSCs grown on our PLLA scaffold exhibited formation of membrane protrusions of uncertain significance, although in a size range and morphology compatible with either motility blebs or shedding vesicles. In summary, our PLLA scaffold has no detrimental effect on a number of features of rat MSCs, primarily the expression of CD73 and CD90.

Abstract
Abstract Duchenne muscular dystrophy (DMD) is a severe hereditary neuromuscular disorder caused by mutations in the dystrophin gene. Antisense-mediated targeted exon skipping has been shown to restore dystrophin expression both in DMD patients and in the mdx mouse, the murine model of DMD, but the ineffective delivery of these molecules limits their therapeutic use. We demonstrated that PMMA/N-isopropil-acrylamide (ZM2) nanoparticles (NPs), administered both intraperitoneally and orally, were able to deliver 2'OMePS antisense inducing various extents of dystrophin restoration in the mdx mice. Defining NP biodistribution is crucial to improve effects on target and dose regimens; thus, we performed in vivo studies of novel ZM4 NPs. ZM4 are conjugated with NIR fluorophores as optical probes suitable for studies on the Odyssey Imaging System. Our results indicate that NPs are widely distributed in all body muscles, including skeletal muscles and heart, suggesting that these vehicles are appropriate to deliver antisense oligonucleotides for targeting striated muscles in the DMD animal model, thus opening new horizons for Duchenne therapy.

Abstract
Objective. The aim of this study was to assess whether the combination of Adapted Physical Activity (APA) and Therapeutic Patient Education (TPE) improves function and quality of life in survivors of strokes. Methods. This nonrandomized controlled study enrolled patients with mild to moderate hemiparesis referred to 2 physical medicine and rehabilitation units in Emilia-Romagna, Italy, 3 to 18 months after a single unilateral mild to moderate stroke. The experimental group (n = 126) received 16 APA sessions and 3 sessions of TPE, and the control group (n = 103) received usual care; 86.9% completed treatment. The main outcome measure was a 4-month change in gait endurance (that corresponds to 2 months after intervention in the experimental group), and secondary outcomes included the Short Physical Performance Battery, Berg Balance Scale, Barthel Index, Geriatric Depression Scale, 12-item Short-Form Health Survey, and Caregiver Strain Index. Changes in scores at 4 months were compared between groups using analysis of variance and controlling for group imbalance by means of the propensity score. Results. Gait endurance, physical performance, balance, and the physical component of the quality of life score increased significantly at 4 months in the APA group and remained stable in the control group. The propensity-adjusted between-group change was significant for these scores at P < .01. Conclusions. Our results confirm that it is feasible and potentially effective to implement APA programs for elderly patients with complex clinical conditions as early as 3 months after a stroke and suggest that, when combined with TPE, the effects of a postrehabilitation APA program are relatively enduring.

Abstract
Vascular calcification decreases compliance and increases morbidity. Mechanisms
of this process are unclear. The role of oxidative stress and effects of
antioxidants have been poorly explored. We investigated effects of the
antioxidants lipoic acid (LA) and tempol in a model of atherosclerosis
associated with elastocalcinosis. Male New Zealand white rabbits (2.5-3.0 kg)
were fed regular chow (controls) or a 0.5% cholesterol (chol)
diet+104 IU/day vitamin D2 (vitD) for 12 weeks, and
assigned to treatment with water (vehicle, n=20), 0.12
mmol·kg-1·day-1 LA (n=11) or 0.1
mmol·kg-1·day-1 tempol (n=15). Chol+vitD-fed rabbits
developed atherosclerotic plaques associated with expansive remodeling, elastic
fiber disruption, medial calcification, and increased aortic stiffness.
Histologically, LA prevented medial calcification by ∼60% and aortic stiffening
by ∼60%. LA also preserved responsiveness to constrictor agents, while
intima-media thickening was increased. In contrast to LA, tempol was associated
with increased plaque collagen content, medial calcification and aortic
stiffness, and produced differential changes in vasoactive responses in the
chol+vitD group. Both LA and tempol prevented superoxide signals with chol+vitD.
However, only LA prevented hydrogen peroxide-related signals with chol+vitD,
while tempol enhanced them. These data suggest that LA, opposite to tempol, can
minimize calcification and compliance loss in elastocalcionosis by inhibition of
hydrogen peroxide generation.

Abstract
Antisense-mediated exon skipping has proven to be efficacious for subsets of Duchenne muscular dystrophy mutations. This approach is based on targeting specific splicing motifs that interfere with the spliceosome assembly by steric hindrance. Proper exon recognition by the splicing machinery is thought to depend on exonic splicing enhancer sequences, often characterized by purine-rich stretches, representing potential targets for antisense-mediated exon skipping. We identified and functionally characterized two purine-rich regions located within dystrophin intron 11 and involved in splicing regulation of a pseudo-exon. A functional role for these sequences was suggested by a pure intronic DMD deletion causing X-linked dilated cardiomyopathy through the prevalent cardiac incorporation of the aberrant pseudo-exon, marked as Alu-exon, into the dystrophin transcript. The first splicing sequence is contained within the pseudo-exon, whereas the second is localized within its 3' intron. We demonstrated that the two sequences actually behave as splicing enhancers in cell-free splicing assays because their deletion strongly interferes with the pseudo-exon inclusion. Cell-free results were then confirmed in myogenic cells derived from the patient with X-linked dilated cardiomyopathy, by targeting the identified motifs with antisense molecules and obtaining a reduction in dystrophin pseudo-exon recognition. The splicing motifs identified could represent target sequences for a personalized molecular therapy in this particular DMD mutation. Our results demonstrated for the first time the role of intronic splicing sequences in antisense modulation with implications in exon skipping-mediated therapeutic approaches.

Abstract
The aim of this study was to assess the effect of human immunodeficiency virus (HIV), hepatitis C (HCV) and B (HBV) virus infection on semen parameters. Semen samples were obtained from 27 HCV, 34 HIV, 30 HBV and 41 HCV-HIV-seropositive patients and compared with those of a control population of healthy seronegative subjects. Tests for detection of HIV, HCV and HBV were performed on seminal samples. The sperm concentration was significantly decreased in HCV- and HBV-seropositive males compared to that of controls (P < 0.001). The mean sperm motility (a + b) was significantly decreased in HCV- and HBV-seropositive (P < 0.001) and in HCV-HIV-seropositive subjects (P < 0.05) compared to that of controls. The sperm viability was significantly lower in HCV- and HBV-seropositive men than in controls (P < 0.001). The normal morphology was significantly reduced in HCV-seropositive and HBV-seropositive men (P < 0.05) with respect to that of controls (P < 0.05). The sperm concentration after sperm wash was significantly higher in controls than in HCV-, HIV-, HBV- and HIV-HCV-seropositive men (P < 0.001). We can conclude that HBV- and HCV-infected men have a significantly impaired sperm quality compared with that of controls. The reason for the better sperm quality in our series of HIV- and HCV-HIV-infected men is still under debate. Further investigations in a larger case series are warranted.

Abstract
Exon skipping using antisense oligonucleotides (AONs) has successfully been used to reframe the mRNA in various Duchenne muscular dystrophy patients carrying deletions in the DMD gene. In this study we tested the feasibility of the exon skipping approach for patients with small mutations in in-frame exons. We first identified 54 disease-causing point mutations. We selected five patients with nonsense or frameshifting mutations in exons 10, 16, 26, 33, and 34. Wild-type and mutation specific 2'OMePS AONs were tested in cell-free splicing assays and in cultured cells derived from the selected patients. The obtained results confirm cell-free splicing assay as an alternative system to test exon skipping propensity when patients' cells are unavailable. In myogenic cells, similar levels of exon skipping were observed for wild-type and mutation specific AONs for exons 16, 26, and 33, whereas for exon 10 and exon 34 the efficacy of the AONs was significantly different. Interestingly, in some cases skipping efficiencies for mutated exons were quite dissimilar when compared with previous reports on the respective wild-type exons. This behavior may be related to the effect of the mutations on exon skipping propensity, and highlights the complexity of identifying optimal AONs for skipping exons with small mutations.

Abstract
Potentially viable therapeutic approaches for Duchenne muscular dystrophy (DMD) are now within reach. Indeed, clinical trials are currently under way. Two crucial aspects still need to be addressed: maximizing therapeutic efficacy and identifying appropriate and sensible outcome measures. Nevertheless, the end point of these trials remains painful muscle biopsy to show and quantify protein restoration in treated boys. In this study we show that PMMA/N-isopropil-acrylamide+ (NIPAM) nanoparticles (ZM2) bind and convey antisense oligoribonucleotides (AONs) very efficiently. Systemic injection of the ZM2-AON complex restored dystrophin protein synthesis in both skeletal and cardiac muscles of mdx mice, allowing protein localization in up to 40% of muscle fibers. The mdx exon 23 skipping level was up to 20%, as measured by the RealTime assay, and dystrophin restoration was confirmed by both reverse transcription-PCR and western blotting. Furthermore, we verified that dystrophin restoration also occurs in the smooth muscle cells of the dorsal skin arrector pili, an easily accessible histological structure, in ZM2-AON-treated mdx mice, with respect to untreated animals. This finding reveals arrector pili smooth muscle to be an appealing biomarker candidate and a novel low-invasive treatment end point. Furthermore, this marker would also be suitable for subsequent monitoring of the therapeutic effects in DMD patients. In addition, we demonstrate herein the expression of other sarcolemma proteins such as alpha-, beta-, gamma- and delta-sarcoglycans in the human skin arrector pili smooth muscle, thereby showing the potential of this muscle as a biomarker for other muscular dystrophies currently or soon to be the object of clinical trials.

Abstract
Background The commonest pathogenic DMD changes are intragenic deletions/duplications which make up to 78% of all cases and point mutations (roughly 20%) detectable through direct sequencing. The remaining mutations (about 2%) are thought to be pure intronic rearrangements/mutations or 5'-3' UTR changes. In order to screen the huge DMD gene for all types of copy number variation mutations we designed a novel custom high density comparative genomic hybridisation array which contains the full genomic region of the DMD gene and spans from 100 kb upstream to 100 kb downstream of the 2.2 Mb DMD gene. Results We studied 12 DMD/BMD patients who either had no detectable mutations or carried previously identified quantitative pathogenic changes in the DMD gene. We validated the array on patients with previously known mutations as well as unaffected controls, we identified three novel pure intronic rearrangements and we defined all the mutation breakpoints both in the introns and in the 3' UTR region. We also detected a novel polymorphic intron 2 deletion/duplication variation. Despite the high resolution of this approach, RNA studies were required to confirm the functional significance of the intronic mutations identified by CGH. In addition, RNA analysis identified three intronic pathogenic variations affecting splicing which had not been detected by the CGH analysis. Conclusion This novel technology represents an effective high throughput tool to identify both common and rarer DMD rearrangements. RNA studies are required in order to validate the significance of the CGH array findings. The combination of these tools will fully cover the identification of causative DMD rearrangements in both coding and non-coding regions, particularly in patients in whom standard although extensive techniques are unable to detect a mutation.

Abstract
AIM The aim of this study was to evaluate the frequency of carbon monoxide diffusing capacity (DLCO) impairment and microalbuminuria in patients with active ulcerative colitis (UC) and to assess whether these nonexpensive and noninvasive tests correlate with intestinal inflammation. METHODS A prospective observational study was set up at the Fiorenzuola Hospital and performed during a 4-year period. We enrolled 30 consecutive subjects with clinical and histological diagnosis of active UC and 20 healthy subjects matched for age and sex. After full colonscopic assessment with multiple mucosal biopsies, the clinical disease activity of each patient was quantified. A global spirometry and 24-h urine collection at rest to measure microalbuminuria were performed. Each biopsy specimen was assessed blindly by a histopathologist, who assigned a score according to the severity of enterocyte damage, cryptitis and acute and chronic inflammation of the lamina propria. RESULTS A latent pulmonary involvement with a reduction in DLCO was present in 20 patients (67%). A subclinical renal involvement with microalbuminuria was detected in 19 subjects (63%). The mean DLCO was 78.2+/-15.2 in Group 1 vs 94.7+/-13.1 in Group 2 (P<0.001). Microalbuminuria was 103.6+/-90.8 in Group 1 vs 57+/-31.7 in the control group (P=0.062). DLCO reduction correlated significantly with intestinal histopathological grading in Group 1 (r = -0.742, P< 0.001), although there was no correlation between microalbuminuria and histological grading (r = -0.273, P= 0.143). CONCLUSION Our data confirm that latent pulmonary involvement (DLCO impairment) and microalbuminuria are frequent in UC. The DLCO may provide a useful noninvasive indicator of colonic inflammation in subjects with UC and concomitant subclinical lung involvement.

Abstract
BACKGROUND Dermatitis herpetiformis may be regarded as the cutaneous counterpart of coeliac disease. These conditions are related to the ingestion of gluten and both are characterised by circulating antibodies against tissue transglutaminase. AIMS To study the distribution of tissue transglutaminase in the skin of dermatitis herpetiformis patients and controls, and to investigate whether the dermal IgA deposits, diagnostic for dermatitis herpetiformis, are related to tissue transglutaminase expression in the skin. METHODS A series of 11 patients with dermatitis herpetiformis had a 4 mm punch biopsy taken from the uninvolved perilesional skin. A group of 16 controls, undergoing surgical removal of benign nevi, gave perilesional skin. Biopsies were covered with OCT and frozen at -80 degrees C. After washing, skin biopsy sections were incubated with an IgG anti-tissue transglutaminase mouse monoclonal antibody. After washing, sections were incubated with anti-mouse IgG. RESULTS The anti-tissue transglutaminase monoclonal antibody specifically recognised the basal epidermal cells. This staining was no different between patients and controls. CONCLUSION Our results suggest that tissue transglutaminase can be recognised in the basal epidermal layer both of patients with dermatitis herpetiformis and controls. Since this distribution does not correspond to the distribution of dermal IgA deposits, it is concluded that dermatitis herpetiformis dermal IgA deposits are not due to antibodies directed against cutaneous tissue transglutaminase.

Abstract
OBJECTIVES The aim of the present study is to analyze the results achieved with the ileal bladder according to the VIP (vescica ileale Padovana) procedure. METHODS/RESULTS We compared the results obtained in 31 patients with invasive bladder cancer who underwent radical surgery (22 underwent the ileal conduit procedure and 9 were treated by orthotopic bladder substitution) and analyzed the early complications, long-term results and physiological data of the group submitted to the VIP procedure. In the patient group submitted to the VIP procedure, there was only one case who required removal of the new bladder due to an enteroneovesical fistula. Another case developed medium serrate anular stricture of the bulbar urethra about 8 months postoperatively and was treated by endoscopic urethrotomy. The uroradiologic and urodynamic evaluations confirmed urinary tract stability integrity of renal function and good adaptation of the new reservoir. The andrological studies showed complete sexual potency in 2 of 9 patients. CONCLUSIONS The VIP procedure appears to be a good technique, with complications no greater than those of traditional urinary diversion, and improves the quality of life of patients undergoing radical surgery for invasive bladder cancer.

Abstract
OBJECTIVE To assess and to follow along the time-span of ICU stay the process of resources allocation and utilization. DESIGN Prospective study. PATIENTS A cohort of 778 patients consecutively admitted to 7 multipurpose general ICU in the Milano area were enrolled in a survey of the daily performed interventions/procedures. MEASUREMENTS AND MAIN RESULTS The majority of diagnostic procedure/interventions were performed during the first two days. The number and quality of interventions were transferred into points obtaining a score system in non-monetary units. The resource allocation process shows a regular trend in the sub-intensive patients who were only monitorized. On the contrary the 258 patients who were intensively treated and survived show a phase of high resource-consumption (about 30 daily points: roughly twice the score of monitorized patients) then followed by a post-intensive phase with a resource consumption resulting in a daily score absolutely equal to the sub-intensive patients. The intensive patients who die show a significantly higher score than survived patients. Both daily and cumulative scores do not show differences among different type of patients. CONCLUSION The evaluation of the process of resources allocation, even if in non-monetary units enables the knowledge of the trend of ICU costs and allows the elaboration of the appropriate budget mechanism.
