Pendulum Exercises After Hip Arthroscopy: A Video Technique.

Advanced hip joint-preserving arthroscopic techniques have been shown to improve patient-reported functional outcomes with low rates of postoperative complications. Prior work has shown that formation of adhesive scar is a potential source of persistent pain and cause for revision surgery. As resources for postoperative in-studio physical therapy become scarce, a home-based strategy to avoid scar formation without adding formal therapy cost may be beneficial.

Efficacy and Safety of OM-85 in Patients with Chronic Bronchitis and/or Chronic Obstructive Pulmonary Disease.

Background: Recurrent acute exacerbations are generally associated with accelerated decline of lung function and characterized by reduced physical activity and worsening of clinical status in patients with chronic obstructive pulmonary disease (COPD). Effective practices and therapies aimed at preventing acute exacerbations are continuously under investigation by healthcare providers. This double-blind, placebo-control, randomized clinical trial sought to evaluate the preventive effect of a bacterial lysate (OM-85) on acute exacerbations in patients with COPD or chronic bronchitis in China.

Influenza-associated Hospitalizations and Deaths, Costa Rica, 2009-2012.

Data needed to guide influenza vaccine policies are lacking in tropical countries. We multiplied the number of severe acute respiratory infections by the proportion testing positive for influenza. There were ≈6,699 influenza hospitalizations and 803 deaths in Costa Rica during 2009-2012, supporting continuation of a national influenza vaccine program.

Identification of VHY/Dusp15 as a regulator of oligodendrocyte differentiation through a systematic genomics approach.

Multiple sclerosis (MS) is a neuroinflammatory disease characterized by a progressive loss of myelin and a failure of oligodendrocyte (OL)-mediated remyelination, particularly in the progressive phases of the disease. An improved understanding of the signaling mechanisms that control differentiation of OL precursors may lead to the identification of new therapeutic targets for remyelination in MS. About 100 mammalian Protein Tyrosine Phosphatases (PTPs) are known, many of which are involved in signaling both in health and disease.

Factors affecting phenological patterns of bombacaceous trees in seasonal forests in Costa Rica and Mexico.

We compared phenological patterns of tree species of the family Bombacaceae in three seasonal forests in Mexico and Costa Rica whose dry seasons vary in duration and intensity. The objectives were to (1) determine intraspecific variation in phenology between sites in different geographic locations with different precipitation regimes, (2) compare interspecific phenological patterns within sites during one year, and (3) document seasonal pollinator use of floral resources at one site in relation to the flowering phenology of these species. To determine the sequence of phenological events in trees of the family Bombacaceae across three study sites, phenology of marked individuals was recorded every 2 wk from September 2000 through August 2001 for six species.
