Predictors of antenatal alcohol use among Australian women: a prospective cohort study.

OBJECTIVE: To identify predictors of antenatal alcohol consumption among women who usually consume alcohol. DESIGN: Prospective cohort study. SETTING: Australian Longitudinal Study on Women's Health (ALSWH). POPULATION OR SAMPLE: A total of 1969 women sampled from the ALSWH 1973-78 cohort. METHODS: Women were included if they were pregnant in 2000, 2003, 2006 or 2009. The relationship between antenatal alcohol consumption and sociodemographics, reproductive health, mental health, physical health, health behaviours, alcohol guidelines and healthcare factors was investigated using a multivariate logistic regression model. MAIN OUTCOME MEASURES: Alcohol use during pregnancy. RESULTS: Most (82.0%) women continued to drink alcohol during pregnancy. Women were more likely to drink alcohol during pregnancy if they had consumed alcohol on a weekly basis before pregnancy (odds ratio [OR] 1.47; 95% confidence interval [95% CI] 1.13-1.90), binge drank before pregnancy (OR 2.28; 95% CI 1.76-2.94), or if they were pregnant while alcohol guidelines recommended low alcohol versus abstinence (OR 1.60; 95% CI 1.26-2.03). Drinking during pregnancy was less likely if women had a Health Care Card (OR 0.63; 95% CI 0.45-0.88) or if they had ever had fertility problems (OR 0.64; 95% CI 0.48-0.86). CONCLUSIONS: Most Australian women who drank alcohol continued to do so during pregnancy. Prepregnancy alcohol consumption was one of the main predictors of antenatal alcohol use. Alcohol guidelines, fertility problems and Health Care Card status also impacted antenatal alcohol consumption.

Total laparoscopic versus open surgery for stage 1 endometrial cancer: the LACE randomized controlled trial.

PURPOSE: Endometrial cancer is the most common gynaecological malignancy in Australia and the US. Current standard treatment involves open surgery to remove the uterus, and both tubes and ovaries (TAH). The Laparoscopic Approach to Cancer of the Endometrium (LACE) trial was designed to assess equivalence of performing this in a total laparoscopic approach (TLH). METHODS: Patient recruitment was designed to proceed along two stages to accommodate for a potential increase in patient requests of laparoscopic surgery. During the first stage, patients are randomised in a 2:1 allocation to receive TLH or TAH, with the primary endpoint quality of life (QoL) at 6 month post-surgery, requiring 180 patients to be enrolled to have 80% power at alpha=0.05 to detect a clinically significant difference of 8 points on the Functional Assessment of Cancer General (FACT-G) QoL instrument. If additional recruitment of patients seems impossible after accrual of 180 patients, this cohort will be followed for 4 years, and disease free survival (DFS) of patients treated by TLH will be compared to DFS within the endometrial cancer population. During the second stage, recruitment will be extended to a total of 590 patients in a 1:1 TLH:TAH allocation, to assess the equivalence with respect to DFS with 80% power and alpha=0.05. Equivalence will be assumed if the difference in DFS does not exceed 7% at 4 years. Secondary outcomes include treatment related morbidity; costs and cost-effectiveness; patterns of recurrence; and overall survival. All data from this multicentre study will be entered using online electronic case report forms (e-CRF), allowing real time assessment of data completeness and patient follow-up. CONCLUSIONS: The LACE trial will establish the equivalence of a TLH approach for patients with stage 1 endometrial cancer following a two stage protocol to accommodate potential threats to patient recruitment through requests for laparoscopic surgery.

Effects of long-term fenofibrate therapy on cardiovascular events in 9795 people with type 2 diabetes mellitus (the FIELD study): randomised controlled trial.

BACKGROUND: Patients with type 2 diabetes mellitus are at increased risk of cardiovascular disease, partly owing to dyslipidaemia, which can be amenable to fibrate therapy. We designed the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study to assess the effect of fenofibrate on cardiovascular disease events in these patients. METHODS: We did a multinational, randomised controlled trial with 9795 participants aged 50-75 years, with type 2 diabetes mellitus, and not taking statin therapy at study entry. After a placebo and a fenofibrate run-in phase, we randomly assigned patients (2131 with previous cardiovascular disease and 7664 without) with a total-cholesterol concentration of 3.0-6.5 mmol/L and a total-cholesterol/HDL-cholesterol ratio of 4.0 or more or plasma triglyceride of 1.0-5.0 mmol/L to micronised fenofibrate 200 mg daily (n=4895) or matching placebo (n=4900). Our primary outcome was coronary events (coronary heart disease death or non-fatal myocardial infarction); the outcome for prespecified subgroup analyses was total cardiovascular events (the composite of cardiovascular death, myocardial infarction, stroke, and coronary and carotid revascularisation). Analysis was by intention to treat. The study was prospectively registered (number ISRCTN 64783481). FINDINGS: Vital status was confirmed on all but 22 patients. Averaged over the 5 years' study duration, similar proportions in each group discontinued study medication (10% placebo vs 11% fenofibrate) and more patients allocated placebo (17%) than fenofibrate (8%; p<0.0001) commenced other lipid treatments, predominantly statins. 5.9% (n=288) of patients on placebo and 5.2% (n=256) of those on fenofibrate had a coronary event (relative reduction of 11%; hazard ratio [HR] 0.89, 95% CI 0.75-1.05; p=0.16). This finding corresponds to a significant 24% reduction in non-fatal myocardial infarction (0.76, 0.62-0.94; p=0.010) and a non-significant increase in coronary heart disease mortality (1.19, 0.90-1.57; p=0.22). Total cardiovascular disease events were significantly reduced from 13.9% to 12.5% (0.89, 0.80-0.99; p=0.035). This finding included a 21% reduction in coronary revascularisation (0.79, 0.68-0.93; p=0.003). Total mortality was 6.6% in the placebo group and 7.3% in the fenofibrate group (p=0.18). Fenofibrate was associated with less albuminuria progression (p=0.002), and less retinopathy needing laser treatment (5.2%vs 3.6%, p=0.0003). There was a slight increase in pancreatitis (0.5%vs 0.8%, p=0.031) and pulmonary embolism (0.7%vs 1.1%, p=0.022), but no other significant adverse effects. INTERPRETATION: Fenofibrate did not significantly reduce the risk of the primary outcome of coronary events. It did reduce total cardiovascular events, mainly due to fewer non-fatal myocardial infarctions and revascularisations. The higher rate of starting statin therapy in patients allocated placebo might have masked a moderately larger treatment benefit.

Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study: baseline characteristics and short-term effects of fenofibrate [ISRCTN64783481].

OBJECTIVE: The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) Study is examining the effects of long-term fibrate therapy on coronary heart disease (CHD) event rates in patients with diabetes mellitus. This article describes the trial's run-in phase and patients' baseline characteristics. RESEARCH DESIGN AND METHODS: FIELD is a double-blind, placebo-controlled trial in 63 centres in 3 countries evaluating the effects of fenofibrate versus placebo on CHD morbidity and mortality in 9795 patients with type 2 diabetes mellitus. Patients were to have no indication for lipid-lowering therapy on randomization, but could start these or other drugs at any time after randomization. Follow-up in the study was to be for a median duration of not less than 5 years and until 500 major coronary events (fatal coronary heart disease plus nonfatal myocardial infarction) had occurred. RESULTS: About 2100 patients (22%) had some manifestation of cardiovascular disease (CVD) at baseline and thus high risk status. Less than 25% of patients without CVD had a (UKPDS determined) calculated 5-year CHD risk of <5%, but nearly all had a 5-year stroke risk of <10%. Despite this, half of the cohort were obese (BMI > 30), most were men, two-thirds were aged over 60 years, and substantial proportions had NCEP ATP III features of the metabolic syndrome independent of their diabetes, including low HDL (60%), high blood pressure measurement (41%), high waist measurement (65%), and raised triglycerides (52%). After a 6-week run-in period before randomisation with all participants receiving 200 mg comicronized fenofibrate, there were declines in total and LDL cholesterol (10%) and triglycerides (26%) and an increase in HDL cholesterol (6.5%). CONCLUSION: The study will show the effect of PPAR-alpha agonist action on CHD and other vascular outcomes in patients with type 2 diabetes including substantial numbers with low to moderate CVD risk but with the various components of the metabolic syndrome. The main results of the study will be reported in late 2005.
