Protocol for Minute Calisthenics: a randomized controlled study of a daily, habit-based, bodyweight resistance training program.

Background: Resistance-training (RT) provides significant health benefits. However, roughly 3/4 of adults in the United States do not meet current Physical Activity Guidelines in this regard. There has been a call for research examining the effectiveness of interventions to increase participation in physical activity and to better understand the dose response relationship upon health outcomes.

Immunoglobulin M nephropathy in a patient with systemic lupus.

Immunoglobulin M (IgM) nephropathy is an uncommon glomerular disease characterized by IgM deposits in the mesangium. This case report describes a 52-year-old woman with a 10-year history of underlying systemic lupus erythematosus with minimal proteinuria who developed sudden onset of nephrotic syndrome. Renal biopsy revealed IgM nephropathy, with no clear evidence of lupus nephritis.

Henoch-Schönlein purpura after etanercept therapy for psoriasis.

Etanercept is a recombinant dimeric fusion protein consisting of a tumor necrosis factor-alpha receptor ligand-binding region linked to the Fc portion of human IgG. It is approved for use in the treatment of rheumatoid arthritis, ankylosing spondylitis, juvenile rheumatoid arthritis, psoriasis, and psoriatic arthritis. Since 1998, there have been reports of vasculitic adverse events, including necrotizing vasculitis and leukocytoclastic vasculitis.

Fabry's Disease Mimicking an Undifferentiated Connective Tissue Disease.

We describe a patient with Fabry's disease who for many years was seen in other clinics and was thought to have an undifferentiated connective tissue disease or an incomplete form of CREST syndrome. He presented with polyarthralgias; multiple telangiectasia-like lesions in his oral mucosa, hands, and periumbilical area; mild dysphagia; Raynaud's phenomenon; bilateral leg lymphedema; renal insufficiency; and aseptic bone necrosis at both knees. The diagnosis of Fabry's disease was first suspected when ultrastructural studies on his kidney revealed the typical inclusions characteristic of glycosphingolipidosis.

A clonal CD4-positive T-cell line established from the blood of a patient with Sézary syndrome.

The reported inability to establish long-term T-cell lines from the blood of cutaneous T-cell lymphoma patients with circulating neoplastic T cells has hindered the development of an in vitro system to investigate Sézary syndrome. We have established a rapidly proliferating T-cell line from the peripheral blood of a patient with Sézary syndrome, which expresses a mature helper T-cell phenotype and contains cytogenetic abnormalities and T-cell receptor gene rearrangements identical to those in the patient's blood. The method of establishment and characteristics of this line are described.
