Comparing Different Sticky Traps to Monitor the Occurrence of Philaenus spumarius and Neophilaenus campestris, Vectors of Xylella fastidiosa, in Different Crops.

Following the detection of the quarantine bacterium Xylella fastidiosa (Wells et al.) in the Apulia region (southern Italy) and the identification of spittlebugs as the main vector species that contributes to its epidemic spread, monitoring activities have been intensified in an attempt to implement vector control strategies. To date, sweep nets have been the most widely used sampling method to monitor adult spittlebug populations. Field experiments were carried out, during 2018 and 2019, to evaluate the effectiveness of sticky traps in capturing spittlebugs in different woody crops. The attractiveness of different traps was compared: four colored sticky traps (white, red, blue, and yellow), with the yellow sticky traps having three different background patterns (plain yellow, yellow with a black circle pattern, and yellow with a black line pattern). In addition, the efficiency of the yellow sticky traps was evaluated by placing the traps on the ground or hanging them from the canopies in orchards with different spittlebug population densities. Trap catches of Philaenus spumarius (Linnaeus) and Neophilaenus campestris (Fallén) (Hemiptera: Aphrophoridae) were compared with those collected using sweep nets. The two spittlebug species showed a similar response to the colored traps and were mainly attracted to the yellow sticky traps. Captures throughout the adult season indicated that an accurate estimation of the presence and abundance of spittlebugs can be obtained by integrating the two sampling methods. Moreover, sweep nets appeared to be more efficient in collecting adults soon after their emergence, while the use of sticky traps was more efficient in the rest of the adult season when the use of traps can significantly expedite vector monitoring programs.

Unmet Nutritional and Psychological Needs of Cancer Patients: An Integrated Multi-Professional Model Approach.

This paper presents a multi-professional integrated approach toward the recognition and management of the nutritional and psychological needs of cancer patients. In particular, the patients undertook a multi-professional, multistep process that included the collection of both personal and clinical data, the evaluation of anthropometric measures, nutritional status and psychometric indices, and an ensuing personalized nutritional prescription and psychological support, ultimately leading to combined nutritional and psychological interventions to control their adherence to a nutritional program and to consolidate motivation to change. Overall, 120 patients were recruited for the study. The majority (84.2%) were female. Breast cancer was by far the most frequent malignancy (52.5%), followed by colorectal (17.5%), pancreatic (9.2%), ovarian (9.2%) and lung (5.0%) cancers. The results of the nutritional and psychological screening at baseline indicated that only 35% of patients had a normal BMI, whilst a relatively high proportion (nearly 32%) was overweight or obese (25%). The INRAN and MEDI-LITE questionnaires, which were used to assess the eating habits and adherence to a Mediterranean diet, respectively, revealed a mixed prevalence of cereals/cereal-based, fresh/processed meat, and fish or fishery food, with a medium-low adherence to the Mediterranean diet in nearly 38% of patients. The BUT, HADS and SF-36 tests, which were used to assess psychological disturbances, showed that 37.5% of patients had disorders regarding body image, 29.2% had abnormal anxiety and 20.0% had a depressive state, while no significant association was observed between the SF-36 PCS and MCS and the patients' characteristics. The results of the potential impact of this novel approach on the QoL of patients after completion of the course are awaited with expectation.

Weekly pegylated liposomal doxorubicin and paclitaxel in patients with metastatic breast carcinoma: A phase II study.

Pegylated liposomal doxorubicin (PLD) has the advantage of delivering active anthracycline directly to the tumor site, while exposing the patient to a lesser degree of doxorubicin-associated toxicities. Recently, a regimen in which paclitaxel is infused weekly over 1 h produced substantial antitumor activity with little myelosuppression. We designed a phase II trial to study the efficacy and toxicity of 10 mg/m(2) PLD on Days 1, 8 and 15, plus 70 mg/m(2) paclitaxel weekly in patients with untreated metastatic breast cancer and a high risk of cardiotoxicity. The study included 35 patients, with 31 (88.5%) evaluable for efficacy and 35 (100%) for toxicity. A total of 28 patients (80%) had two or more sites of disease. Overall, 4 complete and 16 partial responses were noted with an overall response rate of 64.5%, with 6 cases of stable and 5 cases of progressive disease. Toxicity was found to be manageable in that the only grade 3-4 side effects recorded were palmar-plantar erythrodysesthesia, 8.5%; mucositis, 2.8%; leucopenia, 12.5%; anemia, 2.8% and AST/ALT, 2.8%. No cardiotoxicity was observed. In conclusion, weekly PLD plus paclitaxel appears to be a well-tolerated and effective approach for metastatic breast cancer patients with a high risk of cardiotoxicity.

Docetaxel and gemcitabine in the treatment of metastatic breast carcinoma: a dose finding study.

AIMS AND BACKGROUND: Patients with metastatic breast cancer previously treated with anthracyclines for advanced disease are usually refractory to any further treatment with anthracyclines and have a poor prognosis. Therefore, new drugs or new combinations of drugs are needed. One approach has been to focus on the type of chemotherapy with low toxicity that preserves quality of life during treatment, such as weekly drug administration. STUDY DESIGN: We designed a dose-finding study to determine the maximum tolerated dose of gemcitabine plus docetaxel, given on a weekly schedule in metastatic breast cancer previously treated with anthracyclines. Three escalating doses of gemcitabine (900, 1000 and 1100 mg/m2) on days 1 and 8 in combination with a fixed dose of docetaxel, 35 mg/m2 on days 1 and 8 were planned. Dose-limiting toxicity included grade > 3 hematologic toxicity, grade > 2 stomatitis, asthenia, diarrhea or organ-specific toxicity (except alopecia). Dose escalation was stopped if 1 out of 3 patients at any dose level experienced dose-limiting toxicity. RESULTS: Nine patients received a mean of 5.1 (range, 1-9) cycles. Gastrointestinal and leukopenia were the main dose-limiting toxicity. No patient experienced dose-limiting toxicity at dose level 1; at dose level 2, 2 out of 3 patients had dose-limiting toxicity and 3 additional patients treated at dose level 2 confirmed that the maximum tolerated dose had been reached. CONCLUSIONS: The recommended gemcitabine dose in combination with docetaxel (35 mg/m2 for a phase II study) was established at 900 mg/m2.

Gemcitabine combined with carboplatin in patients with malignant pleural mesothelioma: a multicentric phase II study.

BACKGROUND: Malignant pleural mesothelioma (MPM) is increasing rapidly worldwide. Currently, pemetrexed plus cisplatin chemotherapy showed a survival advantage versus cisplatin alone. No impact on patient survival of surgery, radiotherapy, or their combination has been demonstrated. METHODS: Eight centers in northeastern Italy participated in a Phase II multicenter study. Chemotherapy was comprised of carboplatin area under the concentration-time curve 5 on Day 1 and gemcitabine 1000 mg/m(2) on Days 1, 8, and 15. This cycle was repeated every 4 weeks. RESULTS: Between July 1996 and September 2000, 50 patients were treated. Of the sample, 68% were males, 88% had a Eastern Cooperative Oncology Group performance status score of 0-1, 56% had Stage I-II disease, 68% had epithelioid histology, and 62% had no previous treatments. The delivered dose intensity of gemcitabine was 617 mg/m(2) per week, which was 82% of the planned dose (750 mg/m(2) per week). For carboplatin, the delivered dose intensity was 80 mg/m(2) per week. Overall, 44% of 15th day doses were omitted or reduced. Twenty-six percent of the patients had partial responses (95% confidence interval: 15-40%) and 24% had disease progression. None of the patients had complete responses. The median response duration was 55 weeks (range, 13-113 weeks). Patients had good clinical benefit. For example, 46% had improved dyspnea, 40% improved in weight, and 26% experienced pain reduction. Patients developed Grade 3-4 leukopenia during 18 cycles (11%) of chemotherapy. Grade 3-4 thrombocytopenia occurred more frequently, i.e., there were 24 episodes (15%) among 17 patients. Grade 3 anemia developed among patients during eight cycles (5%). None of the patients developed Grade 3-4 nonhematologic toxicity. The median survival of this sample of patients was 66 weeks with 53%, 30%, and 20% of patients alive at 1, 2, and 3 years, respectively. The median progression-free survival period was 40 weeks. CONCLUSIONS: The gemcitabine/carboplatin combination is a valid option in the treatment of MPM due to its acceptable toxicity profile, the good response rate, and the clinical benefit to patients. Minor adjustments in schedule (3-week cycles instead of 4-week cycles) would permit a more optimal treatment administration.
