Ultrastructure of the Spermiogenesis in (Hemiptera: Pentatomidae): X-Irradiation and New Insights on the Centriolar Region Organization.

(Heteroptera: Pentatomidae) is an insect pest native to Asia that has spread over the last two decades to most of the North America, parts of South America, Europe and North Africa. Its impact is significant as it can feed on more than 300 host plants, rendering affected fruits and vegetable crops unsellable or of lower quality. Various chemical and biological methods have been used to control this pest, with varying degrees of success.

Effects of Irradiation on Biology and Mating Behaviour of Wild Males of Brown Marmorated Stink Bug Using a 6 MV Medical Linear Accelerator.

The brown marmorated stink bug, , is a pentatomid bug of Eastern Asian origin that became an economically relevant pest in the Eurasian and American continents. Management of this species is limited to use of chemical insecticides: an inefficient method due to the strong adaptability of the target pest. The sterile insect technique (SIT) is potentially a valid tactic in the search for nontoxic alternatives.

Proton pencil beam scanning reduces secondary cancer risk in breast cancer patients with internal mammary chain involvement compared to photon radiotherapy.

Purpose: Proton pencil beam scanning (PBS) represents an interesting option for the treatment of breast cancer (BC) patients with nodal involvement. Here we compare tangential 3D-CRT and VMAT to PBS proton therapy (PT) in terms of secondary cancer risk (SCR) for the lungs and for contralateral breast.

Methods: Five BC patients including supraclavicular (SVC) nodes in the target (Group 1) and five including SVC plus internal-mammary-nodes (IMNs, Group 2) were considered.

Is the systematic use of mapping systems during His Bundle catheter ablation cost-effective? A single-center experience.

Aim: Three-dimensional (3D) nonfluoroscopic mapping systems (NMSs) are generally used during the catheter ablation (CA) of complex arrhythmias. We evaluated the efficacy, safety, and economic advantages of using NMSs during His-Bundle CA (HB-CA).

Methods: A total of 124 consecutive patients underwent HB-CA between 2012 and 2019 in our EP Laboratory.

[Risk assessment and early predictors of survival after out-of-hospital cardiac arrest in the province of Trento, Italy].

Background: Early prognostication of patients experiencing out-of-hospital cardiac arrest (OHCA) remains difficult, with no recommended risk assessment tool. The aim of this study was to determine and assess the association between available variables with survival at discharge of patients with OHCA in our regional reality.

Methods: We conducted a retrospective observational study in a single-center cohort of 236 consecutive patients with OHCA and return of spontaneous circulation admitted to the S.

Management of patients with cardiac implantable electronic devices (CIED) undergoing radiotherapy: A consensus document from Associazione Italiana Aritmologia e Cardiostimolazione (AIAC), Associazione Italiana Radioterapia Oncologica (AIRO), Associazione Italiana Fisica Medica (AIFM).

The management of patients with a cardiac implanted electronic device (CIED) receiving radiotherapy (RT) is challenging and requires a structured multidisciplinary approach. A consensus document is presented as a result of a multidisciplinary working group involving cardiac electrophysiologists, radiation oncologists and physicists in order to stratify the risk of patients with CIED requiring RT and approaching RT sessions appropriately. When high radiation doses and beam energy higher than 6MV are used, CIED malfunctions can occur during treatment.

Purpose: To prospectively evaluate long-term late rectal bleeding (lrb) and faecal incontinence (linc) after high-dose radiotherapy (RT) for prostate cancer in the AIROPROS 0102 population, and to assess clinical/dosimetric risk factors.

Materials And Methods: Questionnaires of 515 patients with G0 baseline incontinence and bleeding scores (follow-up ≥6 years) were analysed. Correlations between lrb/linc and many clinical and dosimetric parameters were investigated by univariate and multivariate logistic analyses.

Increasing the risk of late rectal bleeding after high-dose radiotherapy for prostate cancer: the case of previous abdominal surgery. Results from a prospective trial.

Purpose: To evaluate and discuss the role of specific types of abdominal surgery (SURG) before radical radiation therapy as a risk factor for late rectal toxicity in prostate cancer patients.

Methods: Results concerning questionnaire-based scored late bleeding and faecal incontinence in 718 patients with a complete follow-up of 36 months were analysed, focusing on the impact of specific pre-radiotherapy abdominal/pelvic surgery procedures. Patients were accrued in the prospective study AIROPROS 0102.

Late fecal incontinence after high-dose radiotherapy for prostate cancer: better prediction using longitudinal definitions.

Purpose: To model late fecal incontinence after high-dose prostate cancer radiotherapy (RT) in patients accrued in the AIROPROS (prostate working group of the Italian Association of Radiation Oncology) 0102 trial using different endpoint definitions.

Methods And Materials: The self-reported questionnaires (before RT, 1 month after RT, and every 6 months for ≤3 years after RT) of 586 patients were available. The peak incontinence (P_INC) and two longitudinal definitions (chronic incontinence [C_INC], defined as the persistence of Grade 1 or greater incontinence after any Grade 2-3 event; and mean incontinence score [M_INC], defined as the average score during the 3-year period after RT) were considered.

Inclusion of clinical risk factors into NTCP modelling of late rectal toxicity after high dose radiotherapy for prostate cancer.

Background And Purpose: To fit an NTCP model including clinical risk factors to late rectal toxicities after radiotherapy for prostate cancer.

Methods And Materials: Data of 669 patients were considered. The probability of late toxicity within 36months (bleeding and incontinence) was fitted with the original and a modified Logit-EUD model, including clinical factors by fitting a subset specific TD(50)s: the ratio of TD(50)s with and without including the clinical variable was the dose-modifying factor (D(mod)).

Optimization of the gafchromic EBT protocol for IMRT QA.

Quality assurance of external beam (radio)therapy (EBT) requires tools with specific characteristics. A radiochromic film dubbed "Gafchromic EBT" (G-EBT) that is particularly suited for external beam therapy because of its features was introduced in 2004. Its characteristics, especially the high spatial resolution, make it suitable for measurement of dose distributions in radiotherapy, especially intensity-modulated radiation therapy (IMRT).

Full-dose intraoperative radiotherapy with electrons in breast cancer. First report on late toxicity and cosmetic results from a single-institution experience.

Purpose: To investigate the feasibility of applying exclusive intraoperative radiation therapy (IORT) after conservative surgery in limited-stage breast carcinoma and to evaluate late effects and cosmetic results after this new conservative treatment.

Patients And Methods: From October 2000 to November 2002, 47 consecutive patients with unifocal breast carcinoma up to a diameter of 2 cm received conservative surgery followed by IORT with electrons as the sole adjuvant local therapy. Three different dose levels were used: 20 Gy (seven patients), 22 Gy (20 patients), and 24 Gy (20 patients).

Rectal dose-volume constraints in high-dose radiotherapy of localized prostate cancer.

Purpose: To investigate the relationship between rectal bleeding and dosimetric-clinical parameters in patients receiving three-dimensional conformal radiotherapy (3D-CRT) for localized prostate cancer.

Methods: In a retrospective national study (AIROPROS01-01, AIRO: Associazione Italiana Radioterapia Oncologica), planning/clinical data for 245 consecutive patients with stage T1-4N0-x prostate carcinoma who underwent 3D-CRT to 70-78 Gy (ICRU point) were pooled from four Italian institutions. The correlation between late rectal bleeding and rectal dose-volume data (the percentage of rectum receiving more than 50, 55, 60, 65, 70, and 75 Gy [V(50-70)]) and other dosimetric and clinical parameters were investigated in univariate (log-rank) and multivariate (Cox regression model) analyses.
