Effects of Attendance to an Organized Fecal Immunochemical Test Screening Program on the Risk of Colorectal Cancer: An Observational Cohort Study.

BACKGROUND & AIMS: This cohort study compared colorectal cancer (CRC) incidence and mortality between people who participated in an Italian regional biennial fecal immunochemical test (FIT) screening program and people who did not. METHODS: The program started in 2005. The target population included over 1,000,000 people aged 50 to 69 years. The FIT was a one-sample OC-Sensor (Eiken Chemical Co, Tokyo, Japan) (cutoff, ≥20 µg hemoglobin/g feces). The average annual response rate to invitation was 51.4%. The records of people invited up to June 2016 were extracted from the screening data warehouse. Attenders were subjects who responded to the first 2 invitations or to the single invitation sent them before they became ineligible. Non-attenders were subjects who did not respond to any of these invitations. The records were linked with the regional CRC registry. People registered up to December 2016 were identified. Self-selection-adjusted incidence rate ratios (IRRs) and incidence-based CRC mortality rate ratios (MRRs) for attenders to non-attenders, with 95% confidence intervals (CIs), were calculated. RESULTS: The cohort generated 2,622,131 man-years and 2,887,845 woman-years at risk with 4490 and 3309 CRC cases, respectively. The cohort of attenders was associated with an IRR of 0.65 (95% CI, 0.61-0.69) for men, 0.75 (95% CI, 0.70-0.80) for women and 0.69 (95% CI, 0.66-0.72) for both sexes combined. The self-selection-adjusted IRR was 0.67 (95% CI, 0.62-0.72) for men and 0.79 (95% CI, 0.72-0.88) for women. The IRR for stage I, II, III, and IV CRC was 1.35 (95% CI, 1.20-1.50), 0.61 (95% CI, 0.53-0.69), 0.60 (95% CI, 0.53-0.68) and 0.28 (95% CI, 0.24-0.32) for men and 1.64 (95% CI, 1.43-1.89), 0.60 (95% CI, 0.52-0.69), 0.73 (95% CI, 0.63-0.85) and 0.35 (95% CI, 0.30-0.42) for women. The overall incidence-based CRC MRR was 0.32 (95% CI, 0.28-0.37) for men, 0.40 (95% CI, 0.34-0.47) for women and 0.35 (95% CI, 0.31-0.39) for both sexes combined. The adjusted MRR was 0.35 (95% CI, 0.29-0.41) for men and 0.46 (95% CI, 0.37-0.58) for women. CONCLUSIONS: Attendance to a FIT screening program is associated with a CRC incidence reduction of 33% among men and 21% among women, and a CRC mortality reduction of 65% and 54%, respectively.

Early menopause is associated with lack of response to antiviral therapy in women with chronic hepatitis C.

BACKGROUND & AIMS: Chronic hepatitis C (CHC) and liver fibrosis progress more rapidly in men and menopausal women than in women of reproductive age. We investigated the associations among menopause, sustained virologic response (SVR), and liver damage in patients with CHC. METHODS: We performed a prospective study of 1000 consecutive, treatment-naïve patients 18 years of age and older with compensated liver disease from CHC. Liver biopsy samples were analyzed (for fibrosis, inflammation, and steatosis) before patients received standard antiviral therapy. From women (n = 442), we collected data on the presence, type, and timing of menopause; associated hormone and metabolic features; serum levels of interleukin-6; and hepatic tumor necrosis factor (TNF)-α. RESULTS: Postmenopausal women achieved SVRs less frequently than women of reproductive age (46.0% vs 67.5%; P < .0001) but as frequently as men (51.1%; P = .283). By multivariate regression analysis, independent significant predictors for women to not achieve an SVR were early menopause (odds ratio [OR], 8.055; 95% confidence interval [CI], 1.834-25.350), levels of γ-glutamyl transpeptidase (OR, 2.165; 95% CI, 1.364-3.436), infection with hepatitis C virus genotype 1 or 4 (OR, 3.861; 95% CI, 2.433-6.134), and cholesterol levels (OR, 0.985; 95% CI, 0.971-0.998). Early menopause was the only independent factor that predicted lack of an SVR among women with genotype 1 hepatitis C virus infection (OR, 3.933; 95% CI, 1.274-12.142). Baseline levels of liver inflammation, fibrosis, steatosis, serum interleukin-6 (P = .04), and hepatic TNF-α (P = .007) were significantly higher among postmenopausal women than women of reproductive age. CONCLUSIONS: Among women with CHC, early menopause was associated with a low likelihood of SVR, probably because of inflammatory factors that change at menopause.

Efficacy, tolerance and safety of new intragastric air-filled balloon (Heliosphere BAG) for obesity: the experience of 17 cases.

BACKGROUND: Overweight and obesity lead to serious health consequences, so that many strategies were recommended for preventing or curing this emerging problem. Treatments are various: diet, physical activity, psychotherapy, drugs, and bariatric surgery. Moreover, during these years, the use of intragastric balloon (BIB) to treat obesity increased rapidly, aimed to (1) reduce bariatric surgical risks; (2) reduce general surgical risks; (3) lead to a significant reduction in the prevalence of cardiovascular diseases, diabetes, musculoskeletal disorders and some cancers. Recently, a new device inflated with air to reduce weight has been developed since 2004 (Heliosphere BAG). METHODS: Between March 2006 and September 2006, in our unit, intragastric air-filled balloon insertion was performed under general anesthesia and endoscopic control. The balloons were removed after 6 months. We evaluated efficacy, tolerance, and safety of this technique. Seventeen patients (eight men, nine women), with a mean age of 43 +/- 10 years (range 18-65), mean basal BMI of 46 +/- 8 (range 35-58) were included, after providing informed consent. Weight and BMI loss were evaluated in all patients. RESULTS: BMI decreased 4 +/- 3 (range +0.33/-11), weight loss was 11 +/- 9 kg (range +1/-29.5; 8.5%). 14/17 patients maintain a BMI > 35 at the time of balloon removal. The difference between initial weight and BMI was statistically significant (p = 0.02 for weight and p < 0.01 for BMI, T Student test). Tolerance was very good, limited only to some dyspeptic symptoms during the first 3 days after insertion. One asymptomatic gastric ulcer was seen at the removal of balloon. Only one severe adverse effect was registered at the time of insertion (acute coronary syndrome in patient with chronic coronary disease). No serious technical problems were noted at balloon insertion. Balloon removal was more difficult and successful in 15/17 cases (one distal migration and one patient led to surgery because of balloon fragmentation). CONCLUSION: Intragastric air-filled balloon showed a good profile of efficacy and tolerance. Weight loss appeared to be equivalent to other type of balloons. On the other hand, technical problems (especially at the time of removal) probably linked to the device's material, set a low safety profile.
