Anti-interleukin-12 antibody for active Crohn's disease

Abstract: background Crohn’s disease is associated with excess cytokine activity mediated by type 1 helper T (Th1) cells. Interleukin-12 is a key cytokine that initiates Th1-mediated inflammatory responses. methods This double-blind trial evaluated the safety and efficacy of a human monoclonal antibody against interleukin-12 (anti–interleukin-12) in 79 patients with active Crohn’s disease. Patients were randomly assigned to receive seven weekly subcutaneous injections of 1 mg or 3 mg of anti–interleukin-12 per kilogram of body weight or placebo, with either a four-week interval between the first and second injection (Cohort 1) or no interruption between the two injections (Cohort 2). Safety was the primary end point, and the rates of clinical response (defined by a reduction in the score for the Crohn’s Disease Activity Index [CDAI] of at least 100 points) and remission (defined by a CDAI score of 150 or less) were secondary end points. results

Convergence of Genes and Cellular Pathways Dysregulated in Autism Spectrum Disorders

Abstract: Rare copy-number variation (CNV) is an important source of risk for autism spectrum disorders (ASDs). We analyzed 2,446 ASD-affected families and confirmed an excess of genic deletions and duplications in affected versus control groups (1.41-fold, p = 1.0 × 10(-5)) and an increase in affected subjects carrying exonic pathogenic CNVs overlapping known loci associated with dominant or X-linked ASD and intellectual disability (odds ratio = 12.62, p = 2.7 × 10(-15), ∼3% of ASD subjects). Pathogenic CNVs, often showing variable expressivity, included rare de novo and inherited events at 36 loci, implicating ASD-associated genes (CHD2, HDAC4, and GDI1) previously linked to other neurodevelopmental disorders, as well as other genes such as SETD5, MIR137, and HDAC9. Consistent with hypothesized gender-specific modulators, females with ASD were more likely to have highly penetrant CNVs (p = 0.017) and were also overrepresented among subjects with fragile X syndrome protein targets (p = 0.02). Genes affected by de novo CNVs and/or loss-of-function single-nucleotide variants converged on networks related to neuronal signaling and development, synapse function, and chromatin regulation.

Resection and liver transplantation for hepatocellular carcinoma.

Abstract: Surveillance programs in cirrhotic patients enable the detection of hepatocellular carcinoma (HCC) at early stages, when the tumor is amenable to curative treatments (60% of cases in Japan; 25 to 40% in Europe and the United States). Resection is the mainstay of treatment in noncirrhotic patients and in cirrhotics with well-preserved liver function. In modern series, a perioperative mortality < or = 3% and 5-year survival rates above 50% are expected. Tumor recurrence complicates half of the cases at 3 years, but there is no unquestionable preventive treatment. Liver transplantation provides excellent outcomes applying the Milan criteria (single nodule < or = 5 cm or two or three nodules < or = 3 cm), with 5-year survival rates of 70% and low recurrence rates. Although expansion of selection criteria is appealing, it should be assessed in the setting of prospective well-designed studies. Intention-to-treat analysis has shown that wide extended indications lead to 25% 5-year survival rates. Living donor liver transplantation is having a minor impact in HCC management. Molecular markers are needed to better select the candidates for surgery.

Use of transesophageal echocardiography to guide cardioversion in patients with atrial fibrillation.

Abstract: Background The conventional treatment strategy for patients with atrial fibrillation who are to undergo electrical cardioversion is to prescribe warfarin for anticoagulation for three weeks before cardioversion. It has been proposed that if transesophageal echocardiography reveals no atrial thrombus, cardioversion may be performed safely after only a short period of anticoagulant therapy. Methods In a multicenter, randomized, prospective clinical trial, we enrolled 1222 patients with atrial fibrillation of more than two days' duration and assigned them to either treatment guided by the findings on transesophageal echocardiography or conventional treatment. The composite primary end point was cerebrovascular accident, transient ischemic attack, and peripheral embolism within eight weeks. Secondary end points were functional status, successful restoration and maintenance of sinus rhythm, hemorrhage, and death. Results There was no significant difference between the two treatment groups in the rate of emboli...
