The effects of caffeine consumption on delayed conception were evaluated in a European multicenter study on risk factors of infertility. Information was collected retrospectively on time of unprotected intercourse for the first pregnancy and the most recent waiting time episode in a randomly selected sample of 3,187 women aged 25-44 years from five European countries (Denmark, Germany, Italy, Poland, and Spain) between August 1991 and February 1993. The consumption of caffeinated beverages at the beginning of the waiting time was used to estimate daily caffeine intake, which was categorized as 0-100, 101-300, 301-500, and > or = 501 mg. Risk of subfecundity (> or = 9.5 months) and the fecundability ratio, respectively, were assessed by logistic regression and Cox proportional hazard analyses, adjusting for age, parity, smoking, alcohol consumption, frequency of intercourse, educational level, working status, use of oral contraceptives, and country. A significantly increased odds ratio (OR) of 1.45 (95% confidence interval (CI) 1.03-2.04) for subfecundity in the first pregnancy was observed for women drinking more than 500 mg of caffeine per day, the effect being relatively stronger in smokers (OR = 1.56, 95% CI 0.92-2.63) than in nonsmokers (OR = 1.38, 95% CI 0.85-2.23). Women in the highest level of consumption had an increase in the time leading to the first pregnancy of 11% (hazard ratio = 0.90, 95% CI 0.78-1.03). These associations were observed consistently in all countries as well as for the most recent waiting time episode. The authors conclude that high levels of caffeine intake may delay conception among fertile women.
"Dark Winds" is making an impact with viewers. The AMC series debuted on Sunday, June 12, with 1.38 million viewers, which is a good showing for the cable network. The series is filmed in New Mexico and based on Tony Hillerman's series. "The Blessing Way" kicked off the series in 1970 and introduced the world to Navajo Tribal Police officers Joe Leaphorn and Jim Chee. The series is set in 1971 on a remote outpost of the Navajo Nation near Monument Valley, Utah, and follows Lt. Joe Leaphorn of the Tribal Police as he is besieged by a series of seemingly unrelated crimes. He is joined on this journey by his new deputy, Jim Chee. Chee, too, has old scores to settle from his youth on the reservation. Together, the two men battle the forces of evil, each other and their own personal demons on the path to salvation. The production filmed in Santa Fe, but will have locations in Espaola, Cochiti Pueblo, Tesuque Pueblo and the Navajo Nation. According to the New Mexico Film Office, the production employed 200 New Mexico crew members and more than 275 New Mexico background and extras. The next episode airs on Sunday, June 19, on AMC and AMC+.
The researchers of the European Organization for Research and Treatment of Cancer (EORTC), Radiation Oncology Group and Genito-Urinary Tract Cancer Group conducted a trial to investigate if brief-term androgen suppression (radiotherapy and 6 months of androgen suppression) could maintain quality of life and obtain the general survival rate achieved with long-term androgen suppression (radiotherapy and 3 years of androgen suppression) in individuals with locally advanced prostate cancer. Almost 1,000 subjects (970) who had had external-beam radiotherapy and 6 months of androgen suppression were allocated in a random way to two groups, one receiving no other treatment (brief-term suppression, 483 patients) and the other receiving further treatment with a luteinizing hormone-releasing hormone agonist for 2.5 years (long-term suppression, 487 patients). Ninety-eight patients in the long-term group and 132 patients in the brief-term suppression group were died after a follow-up period of 6.4 years, and 29 were died because of prostate cancer in the long-term suppression group, compared to 47 in the brief-term group. The general mortality at 5 years for the long-term suppression group was 15.2%, compared to an overall mortality of 19% in the brief-term suppression group, with an observed hazard ratio of 1.42. Statistically significant differences were documented between the groups with reference to insomnia (P = 0.006), hot flushes (P
Sometimes older women are not fully represented in clinical trials, and in particular elderly women affected by breast cancer seem to be not appropriately represented in controlled clinical trials. Since information regarding the impact of adjuvant chemotherapy in these patients is improvable, the researchers of the Cancer and Leukemia Group B (CALGB) (49907 trial) (planned to compare the efficacy of standard chemotherapy, constituted by methotrexate, cyclophosphamide plus fluorouracil or doxorubicin plus cyclophosphamide, with capecitabine) evaluated the non-inferiority of capecitabine compared with standard adjuvant chemotherapy in women affected by breast cancer and aged at least 65 years. Women with stage I, II, IIIA, or IIIB breast cancer were allocated in a random way to standard chemotherapy (cyclophosphamide, methotrexate and fluorouracil or cyclophosphamide and doxorubicin) or capecitabine, and the major end point of this trial was the assessment of survival free of relapse. Recruitment was stopped when the 600th patient was enrolled, because at that time the probability that, with an extended follow-up, capecitabine was much likely to be inferior to standard adjuvant chemotherapy, satisfied a fixed threshold. Following another year, the hazard ratio for relapse or mortality in the capecitabine group was 2.09, with a 95% confidence interval included between 1.38 and 3.17, and a P value
In Italy, stroke is the third determinant of death accounting for more than 10% of total mortality. Mortality within 30 days following a stroke is at least 20%, and mortality within 12 months ranges from 30 to 40%; moreover, stroke constitutes the main cause of invalidity. Stroke, particularly if associated with atrial fibrillation, also carries a significant risk of recurrence, and therefore timely diagnostic patterns are mandatory to begin appropriate anticoagulant therapy.
The authors conclude that improved cardiorespiratory fitness is linked to a decreased risk in overall mortality and in coronary heart disease and cardiovascular disease episodes, and that healthy subjects with a MAC of at least 7.9. METs have significantly minor rates of total mortality and coronary heart disease and cardiovascular disease events when compared with people with a MAC inferior to 7.9 METs.
Cardiovascular diseases are the main determinants of mortality across the world, and coronary heart disease is considered to cost individual European countries national economies billions of euros each year. The authors of this study used information on the number of patients with coronary heart disease and data on clinical and surgical therapy uptake levels to explore the decrease in coronary heart disease mortality potentially obtainable enhancing the availability of dedicated clinical and surgical therapy to eligible subjects in the USA. They have found that in 2000 no more than 60% of eligible individuals in the USA had a sound treatment, and that, by treating 60% of eligible patients, almost 300,000 (297,470, range from 118,360 to 628,120) fewer deaths would have been achieved, constituting 134,635 deaths less than in 2000, with 15% from primary prevention using statins, 19% from the management of acute coronary syndromes, 30% from secondary prevention and 32% from heart failure treatment. Almost 135,000 fewer deaths would be therefore obtained in 2000 augmenting the number of eligible individuals with coronary heart diseases appropriately treated, and consequently current and future care models should be addressed to improve the provision of correct, timely and appropriate treatment to every eligible subject affected by coronary heart disease. In this scenario, in particular secondary prevention and heart failure treatment should be optimised since they account for the highest proportions of clinical benefit.
