Ambiente e salute. Una prospettiva di genere in epidemiologia. - [Environment and health. A gender perspective in epidemiology]
No full textSi è svolto a Lecce dal 14 al 16 novembre di quest’anno “Ambiente e clima. Il presente per il futuro”, convegno annuale dell’Associazione Donne e Scienza organizzato in collaborazione con l’Università del Salento, diversi istituti del Consiglio nazionale delle ricerche e l’Università degli studi di Bari. Il convegno, che ha visto la partecipazione di un centinaio di persone ogni giorno, è stato articolato in quattro sessioni con interventi di donne e uomini attivi nella ricerca e nella comunicazione, di rappresentanti istituzionali, olitici, associazioni ambientaliste e movimenti civici. La sessione “Ambiente e salute: integrare la dimensione di genere” è stata incentrata sugli impatti dei cambiamenti climatici e dell’inquinamento sulla salute. Le diverse relazioni, dalla tossicologia all’epidemiologia ambientale, dalla pratica clinica a quella della medicina di base, hanno messo in evidenza la necessità di trasformare i paradigmi dominanti in medicina ed epidemiologia allargandoli a una prospettiva di genere
Familial colorectal cancer: a concept revisited
No full textOBJECTIVE: The family history of patients with colorectal cancer (CRC) shows an increased risk of disease although evident inherited syndromes are demonstrable in only a small percentage of patients. The purpose of this study was to identify factors that might suggest an inherited component in the transmission of CRC.
METHOD: The study monitored 880 consecutive patients between 1980 and 2005 treated for CRC.
RESULTS: Familial adenomatous polyposis (FAP) was found in only one patient, and a classical mutation of hereditary nonpolyposis colon cancer was found in only two patients. The risk assessment was possible mainly because of factors such as early onset CRC, the presence of multiple primary tumours and a high risk family history. Considering these 36 more patients were suspected to be high risk and referred for further genetic testing. At least one first-degree relative with CRC was reported in 140 patients. In 49 patients, CRC was diagnosed before 50 years of age. Multiple primary tumours, colonic or extra colonic, synchronous or metachronous were found in 136 patients.
CONCLUSION: Our study suggests that if only patients with identified mutations are taken into consideration, then the percentage of evident hereditary colon cancer is very low, but this percentage quickly increases if we make marginal adjustments to the identifying criteria. It seems that it is the physician's clinical suspicion, more than the fulfillment of rigid criteria, which plays a fundamental role in the timely identification and a subsequent focused treatment of patients with hereditary CR
Differenze sesso/genere nella letalità COVID-19: cosa dicono e non dicono i dati - [Sex/gender differences in covid-19 lethality: What the data say, and do not say]
No full textBackground: scientific literature indicates that there are sex, and gender differences in the development, symptomatology and evolution of different diseases, in the response to drugs and in the therapeutic pathways. Even in the COVID-19 epidemic some sex/gender differences emerged. Objectives: to analyze COVID-19 epidemic data by gender and age in Italy, Germany, Spain, and Sweden, characterized by having implemented different pandemic containment policies, with the aim of observing any characteristics that can be interpreted with the lens of sex/gender differences. Materials and methods: we used confirmed cases and deaths associated with COVID-19 for Italy, Spain, Germany, and Sweden from respective national surveillance databases. Mortality data for Italy were also analysed. The period of investigation was March-May 2020. As indicators, we used the case fatality ratio adjusted for time delay and SMR for mortality. Results: women are more vulnerable to COVID- 19 infection in the 30-60-year age group. Case fatality ratio is higher in men than women, with a ratio men/women equal to 1.7 in Italy, Spain, and Sweden and 1,4 in Germany. The ratio increases in the lower age groups. The analysis of the mortality data observed/expected in Italy in the same period with respect to 2015-2019 shows a comparable excess with SMR equal to 132 for men and 127 for women. Conclusions: COVID-19 affects both genders with some differences in the incidence, higher in women, and lethality, higher in men. These differences highlight the need to better understand the sex/gender and age interaction both for epidemiological surveillance and for a better gender-appropriateness of the ongoing prophylactic and therapeutic treatments. This would be possible if all health indicators (symptoms, past illnesses, primary and hospital-level health care, hospitalization, etc.) were provided by age and gender. Analysis of the causes of death could help to better understand the increase in mortality for both genders, in particular for women, for whom a lower lethality for COVID-19 appears from data
Heredity and colorectal cancer
No full textColorectal cancer is the second leading cause of death from malignancies in Western Countries. In spite of advances in treatment, little change in survival has been accomplished in last decades and this mandates greater importance to prevention and early detection. Although dietary factors have received primary attention familial clustering suggests that susceptibility to KCR is inherited. Hereditary colorectal cancer can arise on Familial Adenomatous Polyposis (HCC) or not on polyposis (HNPCC) and members of these families are at high risk of such neoplasias. Anyway, even in "sporadic" forms of KCR first-degree relatives have a 2 to 3-fold increased risk of the same cancer. The most desirable screening protocol would be a simple procedure involving only a blood test to identify gene defect by molecular biology techniques. Unfortunately, this is not practically possible, for lack of specific genetic alterations, out of FAP, and only the study of family history can enable targeted surveillance and cost-effective management strategies
Update on epidemiology and risk factors of colorectal carcinoma [Attualità in tema di epidemiologia e fattori di rischio del carcinoma colo-rettale]
No full textEtiology of colorectal cancer is not completely clear. Epidemiologic studies, especially those on migrant populations, demonstrate the importance of environmental factors, particularly dietary, in cancerogenesis. Anyway, familial aggregation within a given population shows that genetic factors play an important role. General risk factors are represented by age, sex, physical activity... while some pathologies increased the risk of developing KCR or are frankly precancerous (adenomas, ulcerative colitis, Crohn's disease...)
Factors that could influence women's participation in colorectal cancer screening: an Italian study
No full textBackground. Colorectal cancer (CRC) is the 2nd most common cancer in women worldwide. In Italy, only 50% of people invited to get the Fecal Occult Blood Test (FOBT) decided to do it. Women's participation in breast and cervical screening is, instead, very high (>70%). The aim of our study was to investigate the beliefs, the feelings and the psychological factors that could influence the participation of women in CRC screening. Methods.We conducted a cross sectional study, in the Hospital of Siena, Central Italy, in 2011. We administered a questionnaire to 507 women of all ages, who attended mammography or clinical breast examination. The adherence to CRC screening was analyzed only in the group of 207 older women (age >50 years). We performed descriptive, bivariate and logistic regression analysis to identify whether an association was present between participant characteristics, willingness and adherence to screening. Results. Family history of colorectal cancer (OR 4.3; p<0.007) and the General Practitioner's advice (OR: 3.4; p<0.003) were associated with a greater adherence to screening (colonoscopy). The embarrassment was another factor related to colonoscopy compliance (OR: 0.34; p<0.016). Conclusions. Family history of CRC, pain or embarassment and GP's advice are the factors that correlated more strongly (positively or negatively) with adherence to colorectal cancer screening. These elements should be further analyzed to choose the best solution to improve the adherence in campaigns on colorectal cancer
Outcome of surgical treatment of colorectal cancer in the elderly
No full textThe aim of this study is to compare the clinical features and the perioperative and long-term outcomes after primary surgery for colorectal cancer (CRC) in the elderly population with those observed in younger patients. All the patients over the age of 55 who underwent primary surgery for CRC in our clinic from 1988 to 2008 were included in this study and divided into two age groups: 55-75 and >75 years considering the age of diagnosis. 914 consecutive patients were enrolled in the study (352 > 75 years). In the elderly group, tumors were predominantly right sided, and the overall number of comorbidities was statistical more frequent. Elderly patients underwent emergency surgery more than the control group (p = 0.0008). There were no significant differences between the two groups in terms of curative and palliative resections. The overall operative mortality rate was 5.9% in the study group compared with 2.1% in the control study (p = 0.0033). The overall 3-year, 5-year and 10-year survival rates were, respectively, 37, 16.2 and 5.1% in the study group, when compared with 52.3, 35.1 and 24.7% in the control group (p = 0.022, p = 0.0001 and p = 0.0001, respectively). More patients were lost during the follow-up in the elderly group (p = 0.0003) and more deaths unrelated to cancer were found in the study group compared with the control group (p = 0.0005). The cancer specific mortality was similar between the two groups. In conclusion, elderly patients that underwent major colorectal resection have an acceptable perioperative morbidity, mortality and survival rate when compared with younger patients. Age alone should not be considered a reason to deny surgery to these patient
