Outcome after ST elevation myocardial infarction in patients with cancer treated with primary percutaneous coronary intervention.

The simultaneous occurrence of cancer and coronary heart disease is increasing in the Western world. Nevertheless, the influence of cancer on ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) has not been investigated extensively. This multicenter registry included patients with STEMI treated with primary PCI from 2006 to 2009. Patients were stratified according to history of cancer, and primary focus lay on all-cause and cardiac mortalities during 1-year follow-up. Adjusted effect sizes were calculated using Cox proportional hazard models. In total, 208 patients had a history of cancer (diagnosed ≤6 months ago in 20.7%, 6 months to 3 years ago in 21.7%, and >3 years ago in 57.6%) and 3,215 patients had no history of cancer. Chemotherapy had been administered previously to 23% of patients with cancer. Patients with cancer were older, more frequently women, and more commonly known with previous myocardial infarction or anemia. Reperfusion rates were similar after PCI. Patients with cancer showed greater all-cause (17.4% vs 6.5% in other patients) and cardiac mortalities at 1 year (10.7% vs 5.4% in other patients) because of high early cardiac death (23.8%) in recently diagnosed patients with cancer. After adjustment, a recent cancer diagnosis predicted cardiac mortality at 7 days (hazard ratio 3.34, 95% confidence interval 1.57 to 7.08). The adverse prognosis was partly explained by anemia and occurrence of cardiogenic shock, whereas outcome was independent of cancer treatment. In conclusion, patients with cancer showed greater mortality after STEMI. A cancer diagnosis in the 6 months before primary PCI was strongly associated with early cardiac mortality.

Influence of gender on ischemic times and outcomes after ST-elevation myocardial infarction.

Previous studies investigating the influence of gender on ST-segment elevation myocardial infarction have reported conflicting results. The aim of this study was to assess the influence of gender on ischemic times and outcomes after ST-segment elevation myocardial infarction in patients treated with primary percutaneous coronary intervention in modern practice. The present multicenter registry included consecutive patients with ST-segment elevation myocardial infarctions treated with primary percutaneous coronary intervention at 3 hospitals. Adjusted mortality rates were calculated using Cox proportional-hazards analyses. In total, 3,483 patients were included, of whom 868 were women (25%). Women were older, had a higher risk factor burden, and more frequently had histories of malignancy. Men more often had cardiac histories and peripheral vascular disease. Ischemic times were longer in women (median 192 minutes [interquartile range 141 to 286] vs 175 minutes [interquartile range 128 to 279] in men, p = 0.002). However, multivariate linear regression showed that this was due to age and co-morbidity. All-cause mortality was higher at 7 days (6.0% in women vs 3.0% in men, p <0.001) and at 1 year (9.9% in women vs 6.6% in men, p = 0.001). After adjustment, female gender predicted 7 day all-cause mortality (hazard ratio 1.61, 95% confidence interval 1.06 to 2.46) and cardiac mortality (hazard ratio 1.58, 95% confidence interval 1.03 to 2.42) but not 1-year mortality. Moreover, gender was an independent effect modifier for cardiogenic shock, leading to substantially worse outcomes in women. In conclusion, ischemic times remain longer in women because of age and co-morbidity. Female gender independently predicted early all-cause and cardiac mortality after primary percutaneous coronary intervention, and a strong interaction between gender and cardiogenic shock was observed.

Electrosurgical loop excision/conisation for cervical intraepithelial neoplasia in an algorithm that excludes punch biopsy--a study of 210 cases.

UNLABELLED: This study aims to evaluate the use of LLETZ/conisation in an algorithm that excludes the colposcopically guided biopsy. MATERIAL AND METHODS: The study was carried out on 210 patients with LLETZ/conisation, performed in our service in 2 years. They were selected by pap smear, colposcopy, HPV genotyping, without punch biopsy. RESULTS: The pathological results on the excision specimen showed: benign lesion 10%, CIN 1/condyloma 58%, CIN 2 18%, CIN 3/CIS 11%, microinvasion 2% and invasion 1%. The Pap test showed: HGSIL 27%, LGSIL 56%, ASCUS 13%, and normal/benign in 4%. The therapeutic efficiency of the excisional treatment showed that there was a 9.5% excessive treatment, 14.8 residual lesions, 3 cases of hemorrhage, 2 cervical stenosis, and 7 cases with specimen alteration that made the pathological diagnostic difficult or impossible. In conclusion, the LLETZ/conisation are ambulatory procedures with an acceptable rate of over-treatment and residual lesions, and reduced rate of complication.

Efficacy of a new tetravalent coryza vaccine against emerging variant type B strains.

Outbreaks of infectious coryza have been reported in vaccinated flocks in different countries, indicating that new serotype(s) of Haemophilus paragallinarum may have evolved. Several field isolates from vaccinated flocks in the US, Ecuador, Argentina and Zimbabwe were examined and, apart from one serotype C strain, all were typed as serotype B. An inactivated commercial trivalent vaccine, containing serotypes A, B and C, protected against challenge with the serotype C isolate but protection against challenge with serotype B isolates was weaker, suggesting that they might represent a new variant immunotype. An experimental tetravalent oil adjuvant vaccine, containing one of the serotype B isolates, appeared immunogenic against all isolates after one vaccination. Its efficacy and safety were further tested in layer chickens housed under field conditions. Chickens were vaccinated at 8 and 16 weeks of age while controls were unvaccinated. Vaccinates and controls were challenged with type A, B, C and variant type B at 25, 45 or 65 weeks of age. There was good protection (P<0.05) against all four immunotypes after all challenges. No systemic reactions were observed and local reactions were similar to those found with the commercial trivalent vaccine. The tetravalent vaccine may therefore be a good choice for control of new field isolates.
