RESUMO

BACKGROUND:: The research question for this study was as follows: Is the Code of Ethics for Nurses in Italy (Code) a valid or useful decision-making instrument for nurses faced with ethical problems in their daily clinical practice? METHOD:: Focus groups were conducted to analyze specific ethical problems through 11 case studies. The analysis was conducted using sections of the Code as well as other relevant documents. Each focus group had a specific theme and nurses participated freely in the discussions according to their respective clinical competencies. ETHICAL CONSIDERATIONS:: The executive administrative committee of the local nursing licensing council provided approval for conducting this project. Measures were taken to protect the confidentiality of consenting participants. FINDINGS:: The answer to the research question posed for this investigation was predominantly positive. Many sections of the Code were useful for discussion and identifying possible solutions for the ethical problems presented in the 11 cases. CONCLUSION:: We concluded that the Code of Ethics for Nurses in Italy can be a valuable aid in daily practice in most clinical situations that can give rise to ethical problems.

RESUMO

Nowadays, melanoma is one of the most common fatal malignancy of young adults. Incidence is increasing, but mortality rates from melanoma have remained stable. In-transit metastases from extremity or trunk melanoma are subcutaneous or cutaneous deposits of melanoma distant from the primary site, but not reaching the draining nodal basin. According to American Joint Committee on Cancer classification of stages based on Tumor, Node, Metastases classification stages IIIb and IIIc are considered local advanced disease and survival outcomes is quite poor, with 5-year survival rates of 24-54%. Loco-regional recurrence is an important risk factor for distant metastatic disease, either synchrone or metachrone. Therapy for this pattern of recurrence is limited and options vary based on the volume and site of disease. Definitive surgical resection remains the preferred therapeutic approach. However, when surgery cannot be performed with a reasonable cosmetic and functional outcome, other options must be utilized. Treatment options are classified as local, regional, or systemic. The choice of therapy depends on the number of lesions, their anatomic location, whether or not they are dermal or subcutaneous, the size, and the presence or absence of extra-regional disease.

RESUMO

Electroporation uses pulsed, high-intensity electric fields to temporarily increase cell membrane permeability by creation of pores, through which small molecules, such as chemotherapeutic agents, can diffuse inside cells before they reseal. The combination of electroporation with the administration of otherwise low-permeant cytotoxic drugs is known as electrochemotherapy (ECT). The two most commonly used drugs are bleomycin and cisplatin. ECT has already been proven to be effective in diverse tumor histotypes, including melanoma and basal and squamous cell carcinoma, Kaposi sarcoma, and breast cancer, also in those cases nonresponding to classical chemotherapies or other loco-regional treatment modalities, with a good safety profile. ECT can be proposed as loco-regional therapy for disseminated cutaneous and subcutaneous tumor lesions as alternative treatment modality to conventional therapies or as palliative care, in order to improve patients' quality of life.

RESUMO

BACKGROUND: Normal saline is considered a safe alternative for heparin as a locking solution in totally implantable venous access devices. The incidence rate of partial occlusion with the use of normal saline (easy injection, impossible aspiration) is estimated at 4%. OBJECTIVE: The aim of this study was to investigate determinants of partial occlusions with the use of normal saline solution and the maintenance of positive pressure in the catheter. METHODS: We enrolled 218 patients with different solid tumors who underwent pharmacologic treatment through the port with different frequencies: from once every week to at least once every month. The port was flushed with normal saline solution keeping a positive pressure in the catheter. RESULTS: We performed 4111 observations and documented normal port functioning in 99% of observations (n = 4057) and partial occlusions in 1% of observations (n = 54). Partial occlusions were significantly associated with frequency of port flushing (P < .05), chemotherapy (P < .001), and blood sample collection (P < .001). CONCLUSIONS: The use of positive pressure in addition to normal saline reduces the incidence rate of partial occlusions. The type of treatment, blood sample collection, and treatment schedule are important determinants of partial occlusions. IMPLICATIONS FOR PRACTICE: Nurses play a key role in maintaining a functioning port using positive pressure during the flushing techniques. Certain risk factors must be monitored to prevent partial occlusions, and certain patients are more likely to present with port-related problems.

RESUMO

The combined treatment of dacarbazine with an antiangiogenic drug such as bevacizumab may potentiate the therapeutic effects of dacarbazine in metastatic melanoma (MM). Preliminary antitumour activity of dacarbazine plus bevacizumab is evaluated, together with the toxicity and safety profile, in MM patients. This prospective, open-label, phase II study included patients with previously untreated MM or unresectable melanoma. Patients received dacarbazine and bevacizumab until progressive disease or unacceptable toxicity. The primary efficacy variable was the overall response rate. The secondary efficacy parameters included duration of response, duration of stable disease, time to progression/progression-free survival, time to treatment failure and overall survival. The safety analysis included recordings of adverse events and exposure to study treatment. The intention-to-treat population included 37 patients (24 men and 13 women, mean age 54.2±13.1 years). Overall response rate was 18.9% (seven patients achieved a response) and clinical benefit was 48.6%. In patients who achieved a response, the median duration of response was 16.9 months and the median duration of stable disease was 12.5 months. The median time to progression/progression-free survival and time to treatment failure were 5.5 and 3.1 months, respectively. The median overall survival was 11.4 months. Almost all patients (94.6%) experienced at least one adverse event; however, no new area of toxicity of bevacizumab emerged. The dacarbazine/bevacizumab combination provides benefits compared with dacarbazine monotherapy in historical controls, with an acceptable safety profile. This combination appears to be a valid option in specific subgroups of patients, namely, those triple negative (BRAF, C-KIT and NRAS wild type) or with a BRAF mutation who have already received, or are not eligible for, immunomodulating or targeted agents.
