Injectable and Oral Contraceptive Use and Cancers of the Breast, Cervix, Ovary, and Endometrium in Black South African Women: Case–Control Study

Abstract: The NHLS/MRC Cancer Epidemiology Research Group at the National Health Laboratory Service is currently funded by the South African Medical Research Council and the (South African) National Health Laboratory Service; previous funding was received from the University of the Witwatersrand, CANSA (Cancer Association of South Africa), and Cancer Research UK. The Cancer Epidemiology Research Unit at The Cancer Council NSW is funded in the main by The Cancer Council New South Wales. The Cancer Research UK Epidemiology Unit is supported by Cancer Research UK. EB and KC are supported by the Australian National Health and Medical Research Council. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Association of plasma biomarkers of fruit and vegetable intake with incident type 2 diabetes: EPIC-InterAct case-cohort study in eight European countries

Abstract: Objective To investigate the association of plasma vitamin C and carotenoids, as indicators of fruit and vegetable intake, with the risk of type 2 diabetes. Design Prospective case-cohort study. Setting Populations from eight European countries. Participants 9754 participants with incident type 2 diabetes, and a subcohort of 13 662 individuals from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort of 340 234 participants: EPIC-InterAct case-cohort study. Main outcome measure Incident type 2 diabetes. Results In a multivariable adjusted model, higher plasma vitamin C was associated with a lower risk of developing type 2 diabetes (hazard ratio per standard deviation 0.82, 95% confidence interval 0.76 to 0.89). A similar inverse association was shown for total carotenoids (hazard ratio per standard deviation 0.75, 0.68 to 0.82). A composite biomarker score (split into five equal groups), comprising vitamin C and individual carotenoids, was inversely associated with type 2 diabetes with hazard ratios 0.77, 0.66, 0.59, and 0.50 for groups 2-5 compared with group 1 (the lowest group). Self-reported median fruit and vegetable intake was 274 g/day, 396 g/day, and 508 g/day for participants in categories defined by groups 1, 3, and 5 of the composite biomarker score, respectively. One standard deviation difference in the composite biomarker score, equivalent to a 66 (95% confidence interval 61 to 71) g/day difference in total fruit and vegetable intake, was associated with a hazard ratio of 0.75 (0.67 to 0.83). This would be equivalent to an absolute risk reduction of 0.95 per 1000 person years of follow up if achieved across an entire population with the characteristics of the eight European countries included in this analysis. Conclusions These findings indicate an inverse association between plasma vitamin C, carotenoids, and their composite biomarker score, and incident type 2 diabetes in different European countries. These biomarkers are objective indicators of fruit and vegetable consumption, and suggest that diets rich in even modestly higher fruit and vegetable consumption could help to prevent development of type 2 diabetes.

Epidemiology of cancer of the nose and paranasal sinuses: current concepts.

Abstract: Cancer of the nose and paranasal sinuses (SNC) has been attributed to occupational exposure to nickel, chromium, radium, dichlordiethyl sulphide, isopropyl oil, and hydrocarbons. Occupational groups with an increased SNC risk include furniture, boot and show workers, and workers in U.S. countries heavily involved in both petroleum and chemical manufacturing; specific agents have not been identified with certainty. In most of the studies, the risk for developing SNC in the exposed workers was 21 to 100+ times greater than the risk for SNC in those who were not exposed. Undifferentiated and squamous histologies are associated with nickel refining; adenocarcinomas are found in woodworkers, boot and show manufacturers, and textile workers. Most occupations at risk for SNC were also at risk for cancer of other sites, particularly lung and skin cancer. Study of the epidemiology of SNC may identify unrecognized carcinogens and occupational groups at increased cancer risk.
