Background Angiostrongylus vasorum is a nematode residing in the heart and pulmonary vessels of dogs and wild carnivores. In Europe the red fox is its reservoir, while only three records from wolves have been published. Angiostrongylus vasorum has a worldwide distribution, and many pieces of evidence demonstrate that it is spreading from endemic areas to new ones. In Italy, A. vasorum was reported with increasing frequency in dogs and foxes in the last decades, and now it is considered endemic throughout the country. Angiostrongylus vasorum can be asymptomatic or cause respiratory and circulatory disorders, at times causing severe disseminated infections. Methods Between February 2012 and December 2016, 25 wolves found dead in central Italy were submitted to the Istituto Zooprofilattico del Lazio e della Toscana for post-mortem examination. Samples of lungs, heart, liver, spleen, kidneys, mediastinic lymph nodes and brain were collected from each animal for histological examination. When adult and larval nematodes were microscopically seen in lungs, the other organs were processed, and five histological sections for each organ were examined. To confirm parasite identification, lung samples were submitted to a PCR-sequencing protocol targeting the ITS2 region of A. vasorum. Results Seven wolves (28.0%) harboured nematode larvae in lung sections. In two of the positive wolves, adult nematodes were visible in pulmonary arteries, in four animals larvae were also detected in other organs. DNA sequencing reactions confirmed parasite identification as A. vasorum in all the cases. Conclusions As a result of the high prevalence of A. vasorum reported in wolves in the present study, a focus of high circulation could be hypothesised in central Italy. Nevertheless, the similarly high prevalence in foxes originating from the same areas were reported in previous papers. Histopathological evidence highlights the pathogenic potential of A. vasorum in the wolf, especially in juvenile animals.

Despite aggressive multimodality treatment the prognosis of patients with primary brain tumors (BT) remains poor. At present, there are no data about the role of palliative home-care services and their impact on quality of care. We report the results of a pilot project of palliative home care for BT patients started in 2000 in the National Cancer Institute Regina Elena of Rome. We report also the result of a cost/effectiveness analysis utilizing administrative data on re-hospitalization rate in the last two months of life.Since October 2000 until December 2009, 572 patients have been followed by our home care staff. Among 394 patients who died, 276 (70%) were followed at home until death. A cost/effectiveness analysis was carried out evaluating the rehospitalization rate in the last 2 months of life in a subgroup of patients (group 1 assisted at home, 72 patients; group 2 not assisted at home, 71). The number of hospital readmission in the last 2 months of life, and length and cost of hospitalization were retrospectively analyzed from hospital discharge records.Hospitalization rate of group 1 (16.7%) was lower than group 2 (38%) (95% CI: 0.18-0.65, p = 0.001). Costs of hospitalization also differed substantially: 517 Euros (95% CI: 512-522) in group 1 vs 24, 076 Euros (95%: 24,040-24,112 Euros) in group 2.Home-care may represent an alternative to in-hospital care for the management of brain tumor patients and may improve the end-of-life quality of care.

Background The Mini-Mental State Examination (MMSE) has contributed to detecting cognitive impairment, yet few studies have evaluated its accuracy when used by general practitioners (GP) in an actual public-health setting. Objectives We evaluated the accuracy of MMSE scores obtained by GPs by comparing them to scores obtained by Alzheimer's Evaluation Units (UVA). Methods The study was observational in design and involved 59 voluntary GPs who, after having undergone training, administered the MMSE to patients with symptoms of cognitive disturbances. Individuals who scored ≤ 24 (adjusted by age and educational level) were referred to Alzheimer's Evaluation Units (UVA) for diagnosis (including the MMSE). UVAs were unblinded to the MMSE score of the GP. To measure interrater agreement, the weighted Kappa statistic was calculated. To evaluate factors associated with the magnitude of the difference between paired scores, a linear regression model was applied. To quantify the accuracy in discriminating no cognitive impairment from any cognitive impairment and from Alzheimer's disease (AD), the ROC curves (AUC) were calculated. Results For the 317 patients, the mean score obtained by GPs was significantly lower (15.8 vs. 17.4 for the UVAs; p < 0.01). However, overall concordance was good (Kappa = 0.86). Only the diagnosis made by the UVA was associated with the difference between paired scores: the adjusted mean difference was 3.1 for no cognitive impairment and 3.8 for mild cognitive impairment. The AUC of the scores for GPs was 0.80 (95%CI: 0.75–0.86) for discriminating between no impairment and any impairment and 0.89 (95%CI: 0.84–0.94) for distinguishing patients with AD, though the UVA scores discriminated better. Conclusion In a public-health setting involving patients with symptoms of cognitive disturbances, the MMSE used by the GPs was sufficiently accurate to detect patients with cognitive impairment, particularly those with dementia.

Title. Pressure ulcer risk in long-term units: prevalence and associated factors Aim. This paper is a report of a study to assess pressure ulcer prevalence in a group of long-term units and to describe the main factors associated both with risk for and presence of a pressure ulcer. Background. Despite being potentially preventable, pressure ulcers are highly frequent among institutionalized patients and are associated with increased morbidity and mortality. Method. A cross-sectional study was carried out, involving 571 patients from 10 long-term units in Rome, Italy. Healthcare staff in each unit evaluated pressure ulcer risk and collected clinical data while a single Registered Nurse assessed all patients to identify pressure ulcers. Univariate and multivariate analyses were performed for the two outcomes: condition at risk for pressure ulcers (Braden score ≤ 16) and pressure ulcer presence. The data were collected in February-March 2005. Findings. The overall prevalence of pressure ulcers was 27%. Multivariate analysis showed a statistically significant positive association between high-risk condition of pressure ulcer and previous stroke (OR = 1·96; 95% CI 1·30–2·96), previous trauma (OR = 1·83; 95% CI 1·12–2·99) and cognitive decline (OR associated with a 1 point Short Portable Mental State Questionnaire increase = 1·26; 95% CI 1·05–1·50). The model for pressure ulcer presence confirmed a statistically significant excess in patients with cardiovascular diseases (OR = 1·79; 95% CI 1·13–2·85), with high Activity of Daily Living scores (OR associated with a 1 point increase 1·38; 95% CI 1·03–1·84) and low Braden Scale scores (OR associated with a 1 point increase = 0·80; 95% CI 0·70–0·87). The risk of pressure ulcers according to number of full-time nurses and auxiliary staff per 10 beds lower than five was marginally statistically significant (OR = 1·60; 95% CI 0·98–2·61). Conclusion. Further research is needed to validate our findings and further prospective research is needed to identify ways of preventing pressure ulcers. Our data on staffing suggest that organizational factors should be taken into account when exploring determinants of pressure ulcers.
