From a clinical practice perspective, and in terms of the most relevant efficacy measures (PASI 50 and PASI 75) and time points (end of induction phase [week 24] and time to assess primary failure as per the SmPCs), in the currently approved conditions of use ustekinumab is the most efficacious therapeutic alternative for moderate-to-severe plaque psoriasis, followed by infliximab, adalimumab and etanercept.
A community outbreak of Legionella pneumonia in the district of Cerdanyola, Mataró (Catalonia, Spain) was investigated in an epidemiological, environmental and molecular study. Each patient was interviewed to ascertain personal risk-factors and the clinical and epidemiological data. Isolates of Legionella from patients and water samples were subtyped by pulsed-field gel electrophoresis. Between 7 August and 25 August 2002, 113 cases of Legionella pneumonia fulfilling the outbreak case definition criteria were reported, with 84 (74%) cases being located within a 500-m radius of the suspected cooling tower source. In this area, the relative risk of being infected was 54.6 (95% CI 25.3-118.1) compared with individuals living far from the cooling tower. Considering the population residing in the Cerdanyola district (28,256 inhabitants) as a reference population, the attack rate for the outbreak was 399.9 cases/100,000 inhabitants, and the case fatality rate was 1.8%. A single DNA subtype was observed among the ten clinical isolates, and one of the subtypes from the cooling tower matched exactly with the clinical subtype. Nine days after closing the cooling tower, new cases of pneumonia caused by Legionella ceased to appear. The epidemiological features of the outbreak, and the microbiological and molecular investigations, implicated the cooling tower as the source of infection.
This study aimed to assess the efficacy and safety of megestrol acetate (MA) in anorexia-cachexia syndrome (ACS). Literature and relevant databases were searched for randomized controlled trials of MA to treat ACS in patients with cancer, AIDS, or other pathologies. Data were extracted by two independent reviewers, and meta-analyses were performed where possible. Twenty-six studies were included (n=3,887). Compared to placebo, MA increased appetite in oncology patients [RR=2.31 (95% CI 1.52-3.59)], led to weight gain [RR=1.88 (95% CI 1.43-2.47)] and improved HRQOL [RR=1.52 (95% CI 1.00-2.30)]. In AIDS patients, it increased weight [RR=2.16 (95% CI 1.45-3.21)]. MA showed significant benefits over dronabinol in improving appetite, but no statistically significant advantages over other drugs for treating ACS were observed. There were no appreciable differences between lower (<800 mg/day) and higher (>800 mg/day) doses of MA. Few serious adverse events were recorded. MA is an effective and safe treatment for ACS in cancer and AIDS patients, particularly in terms of improvement in appetite and weight gain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
