Effects of Cisplatin in Neuroblastoma Rat Cells: Damage to Cellular Organelles

Cisplatin (cisPt) is a chemotherapy agent used as a treatment for several types of cancer. The main cytotoxic effect of cisplatin is generally accepted to be DNA damage. Recently, the mechanism by which cisPt generates the cascade of events involved in the apoptotic process has been demonstrated. In particular it has been shown that some organelles are cisPt target and are involved in cell death. This paper aims to describe the morphological and functional changes of the Golgi apparatus and lysosomes during apoptosis induced in neuronal rat cells (B50) by cisplatin. The results obtained show that the cellular organelles are the target of cisPt, so their damage can induce cell death

Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

A partnership model between high- And low-volume hospitals to improve results in hepatobiliary pancreatic surgery

Objective: To optimize the results of low-volume (LV) centers for hepatopancreaticobiliary (HPB) surgery. Background: High-volume (HV) centers for HPB surgery have lower mortality than LV. Strategies for collaboration between HV and LV centers are not well investigated. Methods: Postoperative outcomes of patients undergoing curative HPB resection were evaluated at an LV hospital before (2006-2008) and during the collaboration (2009-2012) and at 2 hospitals with HV for either liver or pancreatic resection (2009-2012). Itinerant tutor surgeons from the HV centers were involved in the pre-, intra- And postoperative course of HPB patients at the LV hospital. Results: HPB cases at the LV center increased from 18 to 40 patients per year from 2006 to 2012, whereas 6-month postoperative mortality decreased from 17.8% (2006-2008) to 6% (2009-2012), P < 0.05 (liver: 10.3% vs 4.7% and pancreas: 29.4% vs 7.9%). During the collaborative study period, outcomes for hepatectomy were similar for LV and HV (85 vs 507 cases): postoperative Clavien-Dindo scores 4 and 5 were 2% and 0.2% for HV versus 2.4% and 1.2% for LV, respectively. Outcomes for pancreatic procedures (LV 63 vs HV 269 cases) showed better postoperative Clavien-Dindo scores 4 and 5 in the HV (0.7% score 4 and 1.5% score 5 for HV vs 3.2% and 6.3%, respectively, for LV) but the difference disappeared in the last 2 years (2011-2012) and matching the cases. Conclusions: Our partnership model helped improve postoperative outcomes at the LV center. Results at the LV hospital were comparable with the HV centers, although 2 years of partnership were required to achieve this in pancreatic surgery

Prevalence of a BRCA2 Pathogenic Variant in Hereditary-Breast-and-Ovarian-Cancer-Syndrome Families with Increased Risk of Pancreatic Cancer in a Restricted Italian Area

PVs and LPVs in BRCA1/2 genes are correlated to a high risk of developing breast cancer and/or ovarian cancer (Hereditary Breast and Ovarian Cancer syndrome, HBOC); additionally, in recent years, an increasing number of BRCA 1/2 variants have been identified and associated with pancreatic cancer. Epidemiologic studies have highlighted that inherited factors are involved in 10% to 20% of PCs, mainly through deleterious variants of BRCA2. The frequency of BRCA1/2 germline alterations fluctuates quite a lot among different ethnic groups, and the estimated rate of PVs/LPVs variants in Italian HBOC families is not very accurate, according to different reports. The aim of our study is to describe the prevalence of a BRCA2 PV observed in a selected cohort of HBOC patients and their relatives, whose common origin is the eastern coast of Emilia Romagna, a region of Italy. This study provides insight into the frequency of the variant detected in this area and provides evidence of an increased risk of pancreatic and breast cancer, useful for genetic counseling and surveillance programs

Hope in cancer patients: the relational domain as a crucial factor

15Aims and background: Hope is crucial for patients with cancer. We explored the determinants of hope in patients with cancer using a questionnaire administered over the course of 1 day to an unselected sample of patients at an Italian cancer center. Methods: A team of oncologists, statisticians, and chaplains developed a questionnaire with medical, psychological, spiritual, and religious content. A cross-sectional study was conducted on 320 patients who answered the questionnaire. Results: In the group of participants, 92.8% had a religious belief. Women, patients with limited formal education, and believers were more hopeful. Patients placed trust in God, their partners and children, scientific research, and doctors. On univariate and multivariate analysis, hope was found sensitive to patients' sharing their experiences with others (including family and friends), their positive perception of the people around them, and their relationship with doctors and nurses. Conclusions: If validated in further studies, these results support the notion that a patient with cancer's sense of hope is sensitive to the quality of relationships with caregivers. This may be important to health care organization and resource allocation.nonenoneProserpio T; Ferrari A; Lo Vullo S; Massimino M; Clerici CA; Veneroni L; Bresciani C; Casali PG; Ferrari M; Bossi P; Galmozzi G; Pierantozzi A; Licitra L; Marceglia S; Mariani LProserpio, T; Ferrari, A; Lo Vullo, S; Massimino, M; Clerici, Ca; Veneroni, L; Bresciani, C; Casali, Pg; Ferrari, M; Bossi, P; Galmozzi, G; Pierantozzi, A; Licitra, L; Marceglia, S; Mariani,
