Abstract
BACKGROUND: The development of musculoskeletal disorders (MSDs) associated with forestry operations is an alarming issue. OBJECTIVE: In the present paper, an attempt was made to assess the location and the prevalence of the MSDs in timber harvesting tasks. METHODS: The analysis of logging-related risk factors was carried out by observing working postures with the use of the assessment tool RULA (Rapid Upper Limb Assessment) during harvesting jobs. In addition, the standardised Nordic Musculoskeletal Questionnaire (NMQ) was used in order to record self-reported MSDs symptoms. RESULTS: Results revealed that, in all work stages, risk levels were extremely high. According to the results of the RULA analysis, 77.5% of the working postures adopted by the left side of the body and 61.25% of postures involving the right side belong to the very high-risk level. According to the results of the questionnaire, a high percentage of loggers (34%) reported that they were facing problems in their backs and knees. CONCLUSIONS: Training and informing operators about the correct positions and the manual movement techniques, as well as increasing the mechanisation level of harvesting operations could reduce physiological work hardship.

Abstract
BACKGROUND Frey's syndrome is a well-known complication of parotid surgery; its prevention may be achieved by the use of an interpositional barrier between the overlying flaps and the exposed parenchymal bed of parotid gland. The aim of this study was to retrospectively evaluate clinical outcomes with and without the interpositional placement of a porcine dermal collagen graft (PDCG) for prevention of syndrome occurrence. METHODS We conducted a 20-year retrospective study including the patients who had undergone "formal" (superficial, total, or subtotal) parotidectomies for benign pathologies. The inclusion criteria also involved patients that were (i) regularly monitored about clinical symptoms related to syndrome, and (ii) examined with Minor starch-iodine test. The severity of the diagnosed syndrome was retrospectively evaluated according to the grading score system of Luna-Ortiz. To assess group differences in terms of the extent of dissection in operating sites, we estimated the tumor and histological specimen volumes using the available dimensions. RESULTS We included 73 patients who had undergone 76 formal parotid surgeries. The surgical sites were divided into 2 groups: (1) Group A consisted of 44 sites that were reconstructed with a SMAS flap, and (2) Group B, comprised 32 sites where a PDCG was additionally applied as an artificial preventive barrier. At a mean follow-up of 26.3 months, a significantly lower incidence of clinically diagnosed Frey's syndrome was found after the use of dermal collagen interpositional barrier (P = .031). Specifically, subjective symptoms were reported at an incidence of 31.8% in Group A and 6.7% in Group B. Minor's test was positive at an incidence of 59.09% in Group A and 21.87% in Group B (P = .004, 95% CI). Severe Frey's syndrome was observed in 31.82% of the patients of Group A and in 3.12% of the patients of Group B (P = .002, 95% CI). Since there were no statistical significant differences between the volumes of the removed tumors and the excised histological specimens, the extent of dissection was not proved to influence the occurrence of Frey's syndrome in the compared groups. CONCLUSION Porcine dermal collagen is a safe, practical, and useful means for parotid reconstruction, since it seems to contribute in prevention of Frey's syndrome when increased amount of glandular tissue has to be removed. Additional randomized controlled studies with bigger samples are required to better assess the PDCG use in parotid surgery.

Abstract
BACKGROUND Triflusal has demonstrated an efficacy similar to aspirin in the prevention of vascular events in patients with acute myocardial infarction (ΜΙ) and ischaemic stroke but with less bleeding events. OBJECTIVE We performed a randomised, multicentre, phase 4 clinical trial to compare the clinical efficacy and safety of triflusal versus aspirin, administered for 12 months in patients eligible to receive a cyclooxygenase-1 (COX-1) inhibitor. METHODS Patients with stable coronary artery disease or with a history of non-cardioembolic ischaemic stroke were randomly assigned to receive either triflusal 300 mg twice or 600 mg once daily or aspirin 100 mg once daily for 12 months. The primary efficacy endpoint was the composite of: (a) ΜΙ, (b) stroke (ischaemic or haemorrhagic), or, (c) death from vascular causes for the entire follow-up period. The primary safety endpoints were the rate of bleeding events as defined by Bleeding Academic Research Consortium (BARC) criteria. RESULTS At 12-month follow-up, an equivalent result was revealed between the triflusal (n=559) and aspirin (n=560) in primary efficacy endpoint. Specifically, the combined efficacy outcome rate (i.e. MI, stroke or death from vascular causes) difference was equal to -1.3% (95% confidence interval -1.1 to 3.5) and lied within the a-priori defined equivalence interval (p<0.001). Regarding the primary safety endpoints, patients on triflusal treatment were 50% less likely to develop bleeding events according to the BARC criteria, and especially any clinically overt sign of haemorrhage that requires diagnostic studies, hospitalisation or special treatment (BARC type 2). CONCLUSION The efficacy of triflusal in the secondary prevention of vascular events is similar to aspirin when administered for 12 months. Importantly, triflusal significantly reduced the incidence of ΜΙ and showed a better safety profile compared with aspirin.

Abstract
Abstract Background Brain metastases from sarcomatous lesions pose a management challenge owing to their rarity and the histopathological heterogeneity. Prognostic indices such as the Graded Prognostic Assessment (GPA) index have been developed for several primary tumour types presenting with brain metastases (e.g. lung, breast, melanoma), tailored to the specifics of different primary histologies and molecular profiles. Thus far, a prognostic index to direct treatment decisions is lacking for adult sarcoma patients with brain metastases. Methods We performed a multicentre analysis of a national group of expert sarcoma tertiary centres (French Sarcoma Group, GSF-GETO) with the participation of one Canadian and one Swiss centre. The study cohort included adult patients with a diagnosis of a bone or soft tissue sarcoma presenting parenchymal or meningeal brain metastases, managed between January 1992 and March 2012. We assessed the validity of the original GPA index in this patient population and developed a disease-specific Sarcoma-GPA index. Results The original GPA index is not prognostic for sarcoma brain metastasis patients. We have developed a dedicated Sarcoma-GPA index that identifies a sub-group of patients with particularly favourable prognosis based on histology, number of brain lesions and performance status. Conclusions The Sarcoma-GPA index provides a novel tool for sarcoma oncologists to guide clinical decision-making and outcomes research.

Abstract
In Mediterranean ecosystems an increasing demand for in situ trace gas exchange data is emerging to enhance the adaptation and mitigation strategies under forest degradation. Field-chamber green-house gas fluxes and site characteristics were analysed in two Mediterranean peri-urban pine forests showing degradation symptoms. We examined the effect of different thinning interventions on soil CO2, CH4 and N2O fluxes, addressing the relationships with the environmental variables and C and N contents along forest floor-soil layers. Soil temperature resulted as the main driving variable for CO2 efflux and CH4 uptake. Soil moisture content and organic matter availability affected CO2 emission patterns in the two sites. N2O fluxes showed a positive correlation with soil moisture under wetter climatic conditions only. GHG fluxes showed significant correlations with C and N content of both forest floor and mineral soil, especially in the deepest layers, suggesting that it should be considered, together with environmental variables when accounting GHG fluxes in degraded forests. Short-term effects of thinning on CO2 emissions were dependent on disturbance induced by logging operations and organic matter inputs. After thinning CH4 uptake increased significantly under selective treatment, independently from specific site-induced effects. N2O fluxes were characterized by low emissions in both sites and were not affected by treatments. Soil CO2 efflux was the largest component of global warming potential (GWP) from both sites (11,553 kg ha-1 y-1 on average). Although it has a large global warming potential, N2O contribution to GWP was about 131 kg CO2eq ha-1 y-1. The contribution of CH4-CO2 equivalent to total GWP showed a clear and significant CH4 sink behaviour under selective treatment (36 kg ha-1 y-1 on average). However, in the short-term both thinning approaches produced a weak effect on total GWP.

Abstract
Background: Arbutus unedo is a valuable Mediterranean shrub as an ornamental plant as well as fruit tree. Fresh fruits of A. unedo are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements. Materials and Methods: The effects of gibberellic acid (GA3) and cold stratification (CS) on seed germination performance were investigated in A. unedo seeds collected from three provenances in the Northern part of Greece. Seeds of each provenance were soaked in solutions of GA3 (500, 1000 or 2000 ppm) for 24 h and subsequently were subjected to CS at 3 - 5°C for 0, 1, 2, and 3 months. Results: Non-stratified seeds of the three A. unedo provenances which were not treated with GA3 solutions exhibited very low germination. However, seed germination was significantly improved after a one-month period of CS. Similarly, the non-stratified seeds of all three provenances became non-dormant after the treatment with 2000 ppm GA3 and they germinated at high percentages. However, in untreated seeds with GA3, after a one-month CS period the seeds of the Pieria provenance exhibited higher germination percentage than that of Rodopi provenance seeds. Furthermore, in non-stratified seeds, the Pieria provenance seeds treated with GA3 germinated at higher percentages and more rapidly than those of the other two provenances. Conclusion: The results indicated that untreated seeds exhibited very low germination at 20/25°C. However, in all three provenances seed germinability was significantly improved by a one-month period of CS or treatment of seeds with 2000 ppm GA3. Furthermore, there was a considerable variability among seed provenances in response to the treatments which were applied.

Abstract
We aimed to evaluate the feasibility and reliability of brush cytology in the biomarker expression profiling of oral squamous cell carcinomas within the concept of theranostics, and to correlate this biomarker profile with patient measurable outcomes. Markers representative of prognostic gene expression changes in oral squamous cell carcinoma was selected. These markers were also selected to involve pathways for which commercially available or investigational agents exist for clinical application. A set of 7 markers were analysed by immunocytochemistry on the archival primary tumour material of 99 oral squamous cell carcinoma patients. We confirmed the feasibility of the technique for the expression profiling of oral squamous cell carcinomas. Furthermore, our results affirm the prognostic significance of the epidermal growth factor receptor (EGFR) family and the angiogenic pathway in oral squamous cell carcinoma, confirming their interest for targeted therapy. Brush cytology appears feasible and applicable for the expression profiling of oral squamous cell carcinoma within the concept of theranostics, according to sample availability.

Abstract
Interleukin (IL)-8 promotes cellular proliferation and angiogenesis in patients with non-small-cell lung cancer (NSCLC) and may be related to cachexia. Our aim was to investigate the relationship of IL-8 levels with nutritional status, and clinical outcome of patients with NSCLC. Patients with metastatic NSCLC referred for first-line therapy were eligible. Baseline IL-8 levels were measured in plasma. The Mini Nutritional Assessment (MNA) was used for the evaluation of the nutritional status, and patients were classified into 3 groups: A (score 24-30) "well nourished," B (score 17-23.5) "risk of malnutrition," and C (0-16.5) "malnourishment." Response to first-line chemotherapy, time-to-tumor progression (TTP), and overall survival (OS) were also recorded. In total, 114 patients (101 males, 88.5%; mean age = 67.5 yr) were evaluated. Performance status was 0-1 in 62% of the patients. According to the MNA, the majority of patients (71%) was either at nutritional risk or malnourished. IL-8 levels were significantly different between MNA groups (P = 0.023) and correlated with TTP (P = 0.013) and OS (P = 0.001) in univariate analysis. Baseline IL-8 levels correlate with the nutritional status of patients with metastatic NSCLC, suggesting that this cytokine may be related with cachexia.

INTRODUCTION The aim of this study was to evaluate the sensitivity, specificity, diagnostic accuracy, positive predictive value (PPV) and negative predictive value (NPV) of fine-needle aspiration cytology (FNAC) of salivary gland tumours performed at a tertiary cancer hospital over a time period of 10 years. MATERIALS AND METHODS A retrospective analysis was carried out between 1995 and 2004 to review the cases of patients with salivary gland tumours who had undergone pre-operative FNA and for whom definite histology was either by tru-cut biopsy or by histopathological examination of the operative specimen. RESULTS A total of 107 cases of salivary gland tumours were treated during that period, but only 82 cases diagnosed by FNAC could be correlated with histological and clinical data and were considered for this study. The sensitivity, specificity, diagnostic accuracy, PPV and NPV were estimated considering 54 benign and 28 malignant cases. Sensitivity was 90% (28/31), specificity was 98% (54/55), diagnostic accuracy was 95.1% (82/86), PPV was 96% and NPV was 94%. DISCUSSION This study confirms that FNA cytology is a technique that offers high sensitivity, specificity and diagnostic accuracy in salivary gland tumour diagnosis.

Abstract
BACKGROUND Head and neck cutaneous squamous cell carcinoma (HNCSCC) although rarely fatal has significant adverse public health effects due to high medical costs, compromised quality of life, functional impairment and other serious consequences. The present longitudinal cohort study of HNCSCC was designed to determine whether certain clinical-pathologic features of HNCSCC are associated with reduced overall and recurrence-free survival, as suggested by previous data. PATIENTS The cohort sample consisted of 315 consecutive patients presenting with primary HNCSCC of the head and neck. Life-table analysis and Kaplan-Meier survival analysis were performed. Multivariate Cox's proportional hazards regression models were used to assess the effects of covariates on the length of the interval. RESULTS There were 145 male and 170 female Caucasian patients. At the time of analysis, 222 patients were alive. The mean follow-up time of a patient after enrolment has been 46.7 months (range, 12-124 months). Broder's differentiation grade, perineural involvement, the presence of inflammation and T-stage were independent adjusted predictors for overall survival. pT and N-stage, inflammation and perineural involvement were significant predictors for recurrence-free survival while adjuvant irradiation was associated with a 92% reduced risk for recurrence. Life-table analysis showed that 87% and 69% study patients were free from recurrence at years 3 and 5, respectively. CONCLUSIONS Certain clinico-pathological predictors can be used to discriminate subsets of high-risk patients that could benefit from long-term follow-up. After excision in negative margins, patients with HNCSCC should be referred to specialised multidisciplinary oncology clinics for counselling on adjuvant radiotherapy and follow-up.

Abstract
Purpose The reported incidence of osteonecrosis of the jaw (ONJ) ranges from 0.94% to 18.6%. This cohort study aimed to calculate the incidence of and identify the risk factors for ONJ in patients with cancer treated with intravenous zoledronate, ibandronate, and pamidronate. Patients and Methods Data analyzed included age, sex, smoking status, underlying disease, medical and dental history, bisphosphonates (BP) type, and doses administered. Relative risks, crude and adjusted odds ratios (aORs), and cumulative hazard ratios for ONJ development were calculated. Results We included 1,621 patients who received 29,006 intravenous doses of BP, given monthly. Crude ONJ incidence was 8.5%, 3.1%, and 4.9% in patients with multiple myeloma, breast cancer, and prostate cancer, respectively. Patients with breast cancer demonstrated a reduced risk for ONJ development, which turned out to be nonsignificant after adjustment for other variables. Multivariate analysis demonstrated that use of dentures (aOR = 2.02; 95% CI, 1.03 to 3.96), history of dental extraction (aOR = 32.97; 95% CI, 18.02 to 60.31), having ever received zoledronate (aOR = 28.09; 95% CI, 5.74 to 137.43), and each zoledronate dose (aOR = 2.02; 95% CI, 1.15 to 3.56) were associated with increased risk for ONJ development. Smoking, periodontitis, and root canal treatment did not increase risk for ONJ in patients receiving BP. Conclusion The conclusions of this study validated dental extractions and use of dentures as risk factors for ONJ development. Ibandronate and pamidronate at the dosages and frequency used in this study seem to exhibit a safer drug profile concerning ONJ complication; however, randomized controlled trials are needed to validate these results. Before initiation of a bisphosphonate, patients should have a comprehensive dental examination. Patients with a challenging dental situation should have dental care attended to before initiation of these drugs.
