    Abstract Purpose: Implantable venous access ports are widely used in patients receiving chemotherapy, but there is still scarce evidence about any patient-reported outcome measures. This prospective randomized controlled trial examined the impact on patients' quality-of-life following the placement of an implantable port device for long-term chemotherapy treatment.
    Method: A total of 120 chemotherapy naïve adult outpatients scheduled to receive chemotherapy (duration ≥12 weeks) for solid tissue tumors in a single academic oncology unit were randomly allocated (n = 60 in each arm) between radiologically guided insertion of an implantable venous access port (PORT arm) or standard repeated peripheral venous access (Control arm). Health-related quality-of-life scores (HRQoL) were assessed with the EQ-5D-5L and the oncology-specific EORTC QLQ-C30 (version 3.0) questionnaires at baseline, 3- and 6-months post randomization. Non-parametric tests were applied and differences between medians (Δ) are reported because of skewed-left HRQoL data.
    Results: Baseline clinical and demographic characteristics were well balanced between the two groups. There were no complications during insertion and no infection or device failure in the PORT subjects through the 6-month follow-up. The functional and symptom scales of the EORTC QLQ-C30 questionnaire were similar between both study arms at all time intervals. The EORTC QLQ-C30 global health status was significantly improved in the PORT subjects both at 3 months (Δ: 8.3 out of 100; P = 0.04) and 6 months follow-up (Δ: 16.7 out of 100; P = 0.003). Changes in EQ-5D-5L scores were significantly improved at 6 months in the PORT arm compared to control (Δ: 0.074 out of 1; P = 0.01).
    Conclusions: Implantable venous access ports may confer significantly improved patient-reported quality-of-life benefits in patients receiving chemotherapy for solid tissue tumors.

    Abstract In the framework of Posidonia oceanica (PO) preservation activities, a small-scale restoration pilot project was implemented in 2005 at a Santa Marinella site to replace the loss of this important species of seagrass in this zone of the central Tyrrhenian coast via an innovative transplantation approach. In this context, taking into account the recent advances in the fields of high-resolution (HR) satellite/airborne remote-sensing and genetics laboratory analysis techniques, we propose this integrated methodology for monitoring changes in transplanted meadows in regard to perspective to provide support in the assessment of the entire local PO and seagrass population dynamic. According to specific information requirements in terms of radiometric and spectral/spatial resolution, the multispectral data currently available from the QuickBird polar satellite’s four-band (red, green, blue visible and near-infrared) HR sensor were exploited for methodology implementation using a practical ‘image-based’ approach to account for atmospheric and water column turbidity typical of this mid-coastal Mediterranean region. First, the extents and types of seagrass cover were suitably mapped, and then also the distributions of specific vegetation parameters related to PO dynamics and health were assessed by exploiting the remotely sensed satellite-derived radiance signals and point sea-truth calibration measurements of the bio-genetic parameters. In particular, we implemented maps of leaf area index, genetic similarity, and density Giraud indices corresponding to distributions of PO patches using multivariate and data-mining models (artificial neural network) based on appropriately preprocessed radiometric and auxiliary (bathymetry) input variables.
