Readmissions for treatment for alcoholism

First admissions and readmissions for alcoholism have risen steeply in recent decades. This study looked at readmission histories for four cohorts of alcoholics first admitted to inpatient psychiatric treatment in 1967-68, 1973, 1977 or 1979. Over the twelve years the first cohort was observed, alcoholics on average spent 254 days in treatment and had 2.14 alcohol-related readmissions. However the distributions were very skewed: 50% stayed less than 92 days and 45.6% had no readmissions at all. All four cohorts yielded similar results over comparable time periods and all showed markedly skewed distributions reflecting the diversity of readmission histories among alcoholics. Policy decisions about alcoholism inpatient treatment must take account of this diversity.     

Potential directions for drug development for osteoarthritis

Background: Osteoarthritis (OA) is a frustrating disease for both patient and physician because neither cause nor cure is known and there are currently no disease-modifying drugs. Objective: To review current therapeutic approaches as well as new findings regarding OA pathoetiology that could form the basis of future direction for the development of drugs to prevent or slow down disease progression. Methods: After reviewing disease progression in human OA, as demonstrated by histological analyses, the reasons for cartilage erosion are explored and possible therapeutic approaches are highlighted. Results/conclusions: OA may be an epigenetic disease. This new concept can explain many aspects of the disease and provide reasons why therapeutic approaches until now have met with little success.     

Projections for insulin treatment for diabetics

The evolution of insulin treatment of diabetes has dramatically changed the natural course of this disease. Modern recombinant DNA technology has brought about many new insulin analogues with improved pharmacokinetics, resulting in better glycemic control. In addition, improved insulin delivery systems, such as insulin pumps and pens, have been introduced to provide convenience and to enhance patient compliance. Efforts are currently being devoted to developing noninvasive insulin formulations, such as oral and pulmonary insulin. A number of products are at different stages of clinical trials. Meanwhile, the quest for a permanent cure for diabetes continues. The frontier of diabetes research has gone through a period of substantial expansion, with the emergence of new areas that include gene therapy, islet cell transplantation and diabetic vaccine. Technological breakthroughs, such as recombinant DNA, nanotechnology, microarray-aided genomics and proteomics, will provide more profound insights into the pathogenesis, and the immunological and biological basis of diabetes. Our growing knowledge in these areas will ultimately contribute to the discovery of preventive methods against or a cure for this disease.     

Prospects for MEK inhibitors for treating cancer

Introduction: The MAPK pathway is a signaling network that plays a key role in many normal cellular processes and in a large number of human malignancies. One of its effectors, MEK, is essential for the carcinogenesis of different tumors. In recent years, several drugs able to inhibit MEK have been assessed in clinical trials. Trametinib has recently become the first MEK inhibitor licensed for cancer treatment (advanced melanoma).

Areas covered: We comprehensively review the safety and clinical efficacy of the family of MEK inhibitors, either alone or in combination with other drugs. We discuss data ranging from the Phase III trial of trametinib in melanoma to the most recent drugs with early signs of antitumor activity. In addition, we explain the reasons for the unsuccessful results of the early trials with MEK inhibitors and provide a view of their role in cancer treatment in forthcoming years.

Expert opinion: MEK inhibitors are a potentially safe and active treatment option for the treatment of many human malignancies. The information provided by a large series of studies currently ongoing will be very valuable in order to optimize their use. Adequate selection of patients is crucial for achieving successful results with these compounds.
