- Background: The purpose of this study is to investigate the impact of oxygen therapy on cardiovascular outcomes in relation to sex in patients with confirmed myocardial infarction (MI).Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction trial randomized 6,629 patients to oxygen at 6 L/min for 6-12 hours or ambient air. In the present subgroup analysis including 5,010 patients (1,388 women and 3,622 men) with confirmed MI, we report the effect of supplemental oxygen on the composite of all-cause death, rehospitalization with MI, or heart failure at long-term follow-up, stratified according to sex.Results: Event rate for the composite endpoint was 18.1% in women allocated to oxygen, compared to 21.4% in women allocated to ambient air (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.65-1.05). In men, the incidence was 13.6% in patients allocated to oxygen compared to 13.3% in patients allocated to ambient air (HR 1.03, 95% CI 0.86-1.23). No significant interaction in relation to sex was found (P=.16). Irrespective of allocated treatment, the composite endpoint occurred more often in women compared to men (19.7 vs 13.4%, HR 1.51; 95% CI, 1.30-1.75). After adjustment for age alone, there was no difference between the sexes (HR 1.06, 95% CI 0.91-1.24), which remained consistent after multivariate adjustment.Conclusion: Oxygen therapy in normoxemic MI patients did not significantly affect all-cause mortality or rehospitalization for MI or heart failure in women or men. The observed worse outcome in women was explained by differences in baseline characteristics, especially age

- Introduction: Pemetrexed and erlotinib have been approved as second-line monotherapy for locally advanced or metastatic non-small cell lung cancer (NSCLC). This multicentre, randomised, open-label, parallel phase II study assessed efficacy and safety of pemetrexed versus pemetrexed + erlotinib in patients with advanced non-squamous NSCLC. Methods: NSCLC stage III-IV patients who failed one prior platinum-based chemotherapy regimen, greater than= 1 measurable lesion by Response Evaluation Criteria in Solid Tumors, and Eastern Cooperative Oncology Group performance status less than= 2 were eligible. Patients received pemetrexed 500 mg/m(2) with vitamin B-12 and folic acid q3w alone or combined with erlotinib 150 mg daily. The primary end-point was progression-free survival (PFS). Secondary end-points were overall survival (OS), time-to-treatment failure (TTTF), response and toxicity. Results: Of 165 randomised non-squamous patients, 159 were treated (pemetrexed: 83; pemetrexed + erlotinib: 76). The median PFS (months; 95% CI) was 2.89 (1.94, 3.38) for pemetrexed versus 3.19 (2.86, 4.70) for pemetrexed + erlotinib (hazard ratio [HR] 0.63; 95% CI: (0.44, 0.90); P = 0.0047). The median OS (months; 95% CI) was 7.75 (5.29, 10.41) for pemetrexed versus 11.83 (8.18, 16.66) for pemetrexed + erlotinib (HR: 0.68; 95% CI: 0.46, 0.98; P = 0.019). The median TTTF (months: 95% CI) was 2.4 (1.74, 2.99) for pemetrexed versus 3.0 (2.23, 4.07) for pemetrexed + erlotinib (HR 0.64; 95% CI: 0.46, 0.89; P = 0.0034). One patient died in pemetrexed + erlotinib arm due to febrile neutropenia. Grades 3/4 drug-related toxicities (in greater than= 5% of patients) in pemetrexed/pemetrexed + erlotinib were febrile neutropenia (2.4%/10.5%), diarrhoea (1.2%/5.3%), rash (1.2%/9.2%); anaemia (6%/11.8%), leukopenia (9.6%/23.7%), neutropenia (9.6%/25.0%), and thrombocytopenia (4.8%/14.5%). Conclusions: Pemetrexed + erlotinib treatment significantly improved PFS, OS and TTTF in 2nd line non-squamous NSCLC and was associated with an increase in grade 3/4 toxicities compared with pemetrexed alone.
