Custom Dual Transportation Mode Detection by Smartphone Devices Exploiting Sensor Diversity
Making applications aware of the mobility experienced by the user can open
the door to a wide range of novel services in different use-cases, from smart
parking to vehicular traffic monitoring. In the literature, there are many
different studies demonstrating the theoretical possibility of performing
Transportation Mode Detection (TMD) by mining smart-phones embedded sensors
data. However, very few of them provide details on the benchmarking process and
on how to implement the detection process in practice. In this study, we
provide guidelines and fundamental results that can be useful for both
researcher and practitioners aiming at implementing a working TMD system. These
guidelines consist of three main contributions. First, we detail the
construction of a training dataset, gathered by heterogeneous users and
including five different transportation modes; the dataset is made available to
the research community as reference benchmark. Second, we provide an in-depth
analysis of the sensor-relevance for the case of Dual TDM, which is required by
most of mobility-aware applications. Third, we investigate the possibility to
perform TMD of unknown users/instances not present in the training set and we
compare with state-of-the-art Android APIs for activity recognition.Comment: Pre-print of the accepted version for the 14th Workshop on Context

Neuromuscular adaptations to a motor skills training program for adults with intellectual disabilities
The purpose of this study is to demonstrate the relationship between an injury reduction program and the improvement of stability and muscle strength in adults with intellectual disabilities because, so far, the impact of strength training has been little studied in people with intellectual disabilities. Specifically, a sample of 16 people (aged between 20 and 40) divided randomly into 2 groups: A experimental with specific protocol and control B with traditional program. The training period lasted 3 months with 3 sessions per week. Tests were administered before the start of the program and after 3 months to assess stability and physical fitness. Physical fitness tests assessed the functional aspects of muscle strength and endurance, as well as flexibility. In order to identify the factors associated with the participation of physical activity among active subjects, staff and assisted placement organizations were asked to identify the people they believed to be physically active. The results indicated differences in performance between the two groups. Group A presented better strength in the lower limbs and increased mobility with the use of Pearson's correlation statistical tool and Student's t test. Therefore, the null hypothesis is confirmed
Naturalness consumption and Biodiversity in an Ecoregion of Central Italy
Landscape naturalness and landscape biodiversity are closely connected with ecosystem sustainability. In this study, “naturalness consumption” and “induced biodiversity” created by human interference were evaluated in an ecoregion of Central Italy that represents a meaningful local example of land-use pattern in a Mediterranean environment. A core set of selected indicators and indexes applied to the database produced by GIS was used first to evaluate the landscape naturalness for each phyto-climatic unit and then to calculate the naturalness consumption. Moreover, the landscape biodiversity of each phyto-climate was evaluated, considering the ecomosaic space organization and taking into account the presence of some important ecological structures like ecotones and hedges.
In the naturalness analysis, the highest naturalness consumption occurred in phyto-climates with a higher presence of cultivated areas. In the biodiversity analysis, the phyto-climates with a lower naturalness and a higher presence of agricultural land showed higher values of landscape biodiversity in comparison with the other phyto-climatic units. The results suggest that biodiversity in agro-ecosystems can compensate for naturalness consumption in terms of landscape sustainability. Indeed, natural landscapes carry out a conservative role, while more bio-diverse landscapes offer a balance between human requirements and native ecosystem conditions in a frame of co-evolutionary development
Efficacy and toxicity of bevacizumab in recurrent ovarian disease: an update meta-analysis on phase III trials
Background: To analyze the efficacy and toxicity of bevacizumab on survival outcomes in recurrent ovarian cancer.
Results: Bevacizumab was associated with significant improvement of PFS and OS compared with standard treatment with HRs of 0.53 (95% CI 0.44 - 0.63; p < 0.00001) and 0.87 (95% CI, 0.77 to 0.99; p = 0.03), respectively.
Bevacizumab increased the incidence of G3/G4 hypertension (RR 19.01, 95% CI 7.77 - 46.55; p < 0.00001), proteinuria (RR 17.31, 95% CI 5.42 - 55.25; p < 0.00001), arterial thromboembolic events (ATE) (RR 4.99, 95% CI 1.29 - 19.27; p = 0.02) and bleeding (RR 3.14, 95% CI 1.35 - 7.32; p = 0.008).
Materials and Methods: Three randomized phase III trials representing 1502 patients were identified.
Pooled hazard ratio (HR), odd ratio (OR), risk ratio (RR) with 95% confidence interval (CI) were calculated using fixed or random effects model.
Conclusions: Adding bevacizumab to standard chemotherapy improved ORR, PFS and OS, and it had a higher, but manageable, incidence of toxicities graded 3 to 4
Fertility preservation in gynaecologic cancers
Due to substantial improvement in the diagnosis and treatment of gynaecologic cancers, a better understanding of patient care needs to be revised. We reviewed the literature related to fertility preservation strategies in gynaecological cancer and discussed current general management approaches. New technical modalities and patients’ own desire for motherhood should be integral and paramount in the clinical evaluation to significantly contribute to preserving fertility in those women diagnosed with gynaecologic cancers during the reproductive years
Clinical predictive factors of pathologic complete response in locally advanced rectal cancer
Background: Predictive factors of pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC) are still not identified. The purpose of this study was to define them.
Materials and Methods: Data from consecutive LARC patients treated between January 2008 and June 2014 at our Institution were included in the analysis. All patients were treated with a long course of nCRT. Demographics, initial diagnosis and tumor extension details, as well as treatment modalities characteristics were included in the univariate and logistic regression analysis.
Results: In total 99 patients received nCRT, of whom 23 patients (23.2%) achieved pCR. Patients with and without pCR were similar in term of age, sex, comobidities, BMI and tumor characteristics. Multivariate logistic regression indicated that pre-treatment tumor size <= 5 cm was a significant predictor for pCR (p = 0.035), whereas clinical N stage only showed a positive trend (p = 0.084).
Conclusions: Tumor size at diagnosis could be used to predict pCR, and thus to individualize therapy in LARC patients management. Validation in other studies is needed
Cardio-facio-cutaneous syndrome and gastrointestinal defects: report on a newborn with 19p13.3 deletion including the MAP 2K2 gene
Background: Cardio-facio-cutaneous syndrome (CFCS) belongs to RASopathies, a group of conditions caused by
mutations in genes encoding proteins of the rat sarcoma/mitogen-activated protein kinase (RAS/MAPK) pathway. It is
a rare syndrome, with about 300 patients reported. Main clinical manifestations include facial dysmorphisms, growth
failure, heart defects, developmental delay, and ectodermal abnormalities. Mutations (mainly missense) of four genes
(BRAF, MAP 2 K1, MAP 2 K2, and KRAS) have been associated to CFCS. However, whole gene deletions/duplications and
chromosomal microdeletions have been also reported. Specifcally, 19p13.3 deletion including MAP 2 K2 gene are
responsible for cardio-facio-cutaneous microdeletion syndrome, whose afected subjects show more severe phenotype than CFCS general population.
Case presentation: Hereby, we report on a female newborn with prenatal diagnosis of omphalocele, leading to further genetic investigations through amniocentesis. Among these, array comparative genomic hybridization (a-CGH)
identifed a 19p13.3 microdeletion, spanning 1.27Mb and including MAP 2 K2 gene. Clinical features at birth (coarse
face with dysmorphic features, sparse and friable hair, cutaneous vascular malformations and hyperkeratotic lesions,
interventricular septal defect, and omphalocele) were compatible with CFCS diagnosis, and further postnatal genetic
investigations were not considered necessary. Soon after discharge, at around 1month of life, she was readmitted to
our Neonatal Intensive Care Unit due to repeated episodes of vomiting, subtending a hypertrophic pyloric stenosis
(HPS) which was promptly identifed and treated.
Conclusions: Our report supports the 19p13.3 microdeletion as a contiguous gene syndrome, in which the involvement of the genes contiguous to MAP 2 K2 may modify the patients’ phenotype. It highlights how CFCS afected
subjects, including those with 19p13.3 deletions, may have associated gastrointestinal defects (e.g., omphalocele
and HPS), providing further data on 19p13.3 microdeletion syndrome, and a better characterization of its genomic
and phenotypic features. The complex clinical picture of such patients may be worsened by additional, and even
precocious, life-threatening conditions like HPS. Clinicians must consider, anticipate and/or promptly treat possible
medical and surgical complications, with the aim of reducing adverse outcomes. Extensive diagnostic work-up, and
early, continuous, and multidisciplinary follow-up, as well as integrated care, are necessary for the longitudinal clinical
evolution of any single patient
