TL;DR: Atezolizumab was not associated with significantly longer overall survival than chemotherapy in patients with platinum-refractory metastatic urothelial carcinoma overexpressing PD-L1, thus precluding further formal statistical analysis.

TL;DR: The use of parecoxib and valdecoxib after CABG was associated with an increased incidence of cardiovascular events, arousing serious concern about the use of these drugs in such circumstances.
Abstract: background Valdecoxib and its intravenous prodrug parecoxib are used to treat postoperative pain but may involve risk after coronary-artery bypass grafting (CABG). We conducted a randomized trial to assess the safety of these drugs after CABG. methods In this randomized, double-blind study involving 10 days of treatment and 30 days of follow-up, 1671 patients were randomly assigned to receive intravenous parecoxib for at least 3 days, followed by oral valdecoxib through day 10; intravenous placebo followed by oral valdecoxib; or placebo for 10 days. All patients had access to standard opioid medications. The primary end point was the frequency of predefined adverse events, including cardiovascular events, renal failure or dysfunction, gastroduodenal ulceration, and wound-healing complications. results As compared with the group given placebo alone, both the group given parecoxib and valdecoxib and the group given placebo and valdecoxib had a higher proportion of patients with at least one confirmed adverse event (7.4 percent in each of these two groups vs. 4.0 percent in the placebo group; risk ratio for each comparison, 1.9; 95 percent confidence interval, 1.1 to 3.2; P=0.02 for each comparison with the placebo group). In particular, cardiovascular events (including myocardial infarction, cardiac arrest, stroke, and pulmonary embolism) were more frequent among the patients given parecoxib and valdecoxib than among those given placebo (2.0 percent vs. 0.5 percent; risk ratio, 3.7; 95 percent confidence interval, 1.0 to 13.5; P=0.03). conclusions The use of parecoxib and valdecoxib after CABG was associated with an increased incidence of cardiovascular events, arousing serious concern about the use of these drugs in such circumstances.

TL;DR: It is reported here that the new CRF is more potent than vasopressin in releasing ACTH and potentiation of CRF activity with steep dose–response characteristics was observed, suggesting that thenew CRF does not account for all the non-vasopressIn portion of the CRF complex.
Abstract: Initially the hypothalamic factor responsible for the release of corticotropin (CRF), was thought to be a simple peptide. More recent work has led to the conclusion that CRF is a multifactorial complex. In 1979 we proposed that vasopressin, much disputed as a CRF candidate, was a major constituent of the complex, interacting with a potentiating the CRF activity of the other component(s). The recent characterization of a 41 residue ovine hypothalamic peptide capable of releasing adrenocorticotropic hormone (ACTH) in a dose-related manner has allowed us to compare its CRF bioactivity with that of vasopressin and simple extracts of the hypothalamus, and to investigate any interaction it may have with vasopressin and other hypothalamic factors in the release of ACTH. We report here that the new CRF is more potent than vasopressin in releasing ACTH. When given simultaneously with vasopressin a fourfold potentiation of CRF activity with steep dose-response characteristics were observed. It also potentiated vasopressin-free hypothalamic extracts, suggesting that a new CRF does not account for all the nonvasopressin portion of the CRF complex.

TL;DR: It is concluded that if a reliable and consistent method of measuring quality of life in cancer patients is required, it must come from the patients themselves and not from their doctors and nurses.
Abstract: The extent to which a doctor or health professional can make a valid assessment of a patient's quality of life, anxiety and depression was investigated in a series of cancer patients. Doctors and patients filled out the same forms, viz. the Karnofsky, Spitzer, Linear Analogue Self Assessment Scales and a series of simple scales designed for this study, at the same time. Correlations between the two sets of scores were poor, suggesting that the doctors could not accurately determine what the patients felt. A further study examining the reproducibility of these scales demonstrated considerable variability in results between different doctors. It is concluded that if a reliable and consistent method of measuring quality of life in cancer patients is required, it must come from the patients themselves and not from their doctors and nurses.

TL;DR: The new screening method would detect over 60% of affected pregnancies, more than double that achievable with the same amniocentesis rate in existing programmes, and could reduce the number of children born with Down's syndrome in the United Kingdom from about 900 a year to about 350 a year.
Abstract: The possibility of improving the effectiveness of antenatal screening for Down's syndrome by measuring human chorionic gonadotrophin concentrations in maternal serum during the second trimester to select women for diagnostic amniocentesis was examined. The median maternal serum human chorionic gonadotrophin concentration in 77 pregnancies associated with Down's syndrome was twice the median concentration in 385 unaffected pregnancies matched for maternal age, gestational age, and duration of storage of the serum sample. Measuring human chorionic gonadotrophin in maternal serum was an effective screening test, giving a lower false positive rate (3%) at a 30% detection rate than that for maternal age (5%) and the two existing serum screening tests, unconjugated oestriol (7%) and alpha fetoprotein (11%). The most effective screening results were obtained with all four variables combined; at the same 30% detection rate the false positive rate declined to 0.5%. The new screening method would detect over 60% of affected pregnancies, more than double that achievable with the same amniocentesis rate in existing programmes (5%), and could reduce the number of children born with Down's syndrome in the United Kingdom from about 900 a year to about 350 a year.
