Rural governance and livelihoods systems diversification in the Western Balkans: comparative case studies of Bosnia and Herzegovina, Montenegro and Serbia

Agriculture is still important for socio-economic development in rural areas of Bosnia, Montenegro and Serbia (BMS). However, for sustainable rural development rural economies should be diversified so attention should be paid also to off-farm and non-farm income-generating activities. Agricultural and rural development (ARD) processes and farm activity diversification initiatives should be well governed. The ultimate objective of this work is to explore linkages between ARD governance and rural livelihoods diversification in BMS. The thesis is based on an extended secondary data analysis and surveys. Questionnaires for ARD governance and coordination were sent via email to public, civil society and international organizations. Concerning rural livelihood diversification, the field questionnaire surveys were carried out in three rural regions of BMS. Results show that local rural livelihoods are increasingly diversified but a significant share of households are still engaged in agriculture. Diversification strategies have a chance to succeed taking into consideration the three rural regions’ assets. However, rural households have to tackle many problems for developing new income-generating activities such as the lack of financial resources. Weak business skills are also a limiting factor. Fully exploiting rural economy diversification potential in BMS requires many interventions including improving rural governance, enhancing service delivery in rural areas, upgrading rural people’s human capital, strengthening rural social capital and improving physical capital, access of the rural population to finance as well as creating a favourable and enabling legal and legislative environment fostering diversification. Governance and coordination of ARD policy design, implementation and evaluation is still challenging in the three Balkan countries and this has repercussions also on the pace of rural livelihoods diversification. Therefore, there is a strong and urgent need for mobilization of all rural stakeholders and actors through appropriate governance arrangements in order to foster rural livelihoods diversification and quality of life improvement.

IGF system, CD99 and tumor-specific chromosomal translocations: evaluation of their cross-talk and definition of their role in Ewing sarcoma and prostate cancer

Aberrant expression of ETS transcription factors, including FLI1 and ERG, due to chromosomal translocations has been described as a driver event in initiation and progression of different tumors. In this study, the impact of prostate cancer (PCa) fusion gene TMPRSS2-ERG was evaluated on components of the insulin-like growth factor (IGF) system and the CD99 molecule, two well documented targets of EWS-FLI1, the hallmark of Ewing sarcoma (ES). The aim of this study was to identify common or distinctive ETS-related mechanisms which could be exploited at biological and clinical level. The results demonstrate that IGF-1R represents a common target of ETS rearrangements as ERG and FLI1 bind IGF-1R gene promoter and their modulation causes alteration in IGF-1R protein levels. At clinical level, this mechanism provides basis for a more rationale use of anti-IGF-1R inhibitors as PCa cells expressing the fusion gene better respond to anti-IGF-1R agents. EWS-FLI1/IGF-1R axis provides rationale for combination of anti-IGF-1R agents with trabectedin, an alkylator agent causing enhanced EWS-FLI1 occupancy on the IGF-1R promoter. TMPRSS2-ERG also influences prognosis relevance of IGF system as high IGF-1R correlates with a better biochemical progression free survival (BPFS) in PCa patients negative for the fusion gene while marginal or no association was found in the total cases or TMPRSS2-ERG-positive cases, respectively. This study indicates CD99 is differentially regulated between ETS-related tumors as CD99 is not a target of ERG. In PCa, CD99 did not show differential expression between TMPRSS2-ERG-positive and –negative cells. A direct correlation was anyway found between ERG and CD99 proteins both in vitro and in patients putatively suggesting that ERG target genes comprehend regulators of CD99. Despite a little trend suggesting a correlation between CD99 expression and a better BPFS, no clinical relevance for CD99 was found in the field of prognostic biomarkers.

Guidelines of Special Care Dentistry in Patients with Chromosomal and Genetic syndromes

Chromosomal and genetic syndromes are frequently associated with dental and cranio-facial alterations. The aim of our study is to identify and describe the dental and craniofacial alterations typical of six genetic and chromosomal syndromes examined. Materials and Methods- A dental visit was performed to 195 patients referred from Sant’Orsola Hospital of Bologna, University of Bologna, to Service of Special Need Dentistry, Dental Clinic, Department of Biomedical and Neuromotor Science, University of Bologna. The patients recruited were 137 females and 58 males, in an age range of 3-49 years (mean age of 13.8±7.4). The total sample consisted of subjects affected with Down Syndrome (n=133), Familiar Hypophosphatemic Ricket (n=10), Muscular Dystrophies (n=12), Noonan Syndrome (n=13), Turner Syndrome (n=17), Williams Syndrome(n=10). A questionnaire regarding detailed medical and dental history, oral health and dietary habits, was filled by parents/caregivers, or patients themselves when possible. The intra-oral and extra-oral examination valued the presence of facial asymmetries, oral habits, dental and skeletal malocclusions, dental formula, dental anomalies, Plaque Index (Silness&LÖe Index), caries prevalence (dmft/DMFT index), gingivitis and periodontal disease, and mucosal lesions. Radiographic examinations (Intraoral radiographies, Orthopanoramic, Skull teleradiography) were executed according to patient’s age and treatment planning. A review of literature about each syndrome and its dental and cranio-facial characteristics and about caries, hygiene status and malocclusion prevalence on syndromic and non-syndromic population was performed. Results - The data of all the patients were collected in the “Data Collection Tables” created for each syndrome. General anamnesis information, oral hygiene habits and dmft/DMFT, PI, malocclusion prevalence were calculated and compared to syndromic and non-syndromic population results found in literature. Discussions and conclusions - Guidelines of Special Care dentistry were indicated for each syndrome, in relation to each syndrome features and individual patient characteristics.
