A cross-sectional survey of policies guiding second stage labor in urban Japanese hospitals, clinics and midwifery birth centers.

Background: The Japan Academy of Midwifery developed and disseminated the '2012 Evidence-based Guidelines for Midwifery Care (Guidelines for Midwives)' for low-risk births to achieve a more uniform standard of care during childbirth in Japan. The objective of this study was to cross-sectional survey policy implementation regarding care during the second stage of labor at Japanese hospitals, clinics, and midwifery birth centers, and to compare those policies with the recommendations in Guidelines for Midwives.

Methods: This study was conducted in the four major urbanized areas (e.

Rheumatoid neutrophilic dermatosis with tense blister formation: a case report and review of the literature.

We report a 78-year-old woman with rheumatoid neutrophilic dermatosis (RND) presenting with tense blisters; an extremely rare manifestation of this condition. Systemic corticosteroid was of limited efficacy, while dapsone was effective. A literature review of four similar cases showed that tense blisters in this type of RND tended to appear on the lower extremities of aged, female rheumatoid arthritis patients.

Cell surface biotinylation by azaelectrocyclization: easy-handling and versatile approach for living cell labeling.

Versatile method for living cell labeling has been established. Cell surfaces are initially biotinylated by azaelectrocyclization, and then treated with the fluorescence-labeled avidin or the anti-biotin antibody.

Imbalanced production of cytokines by T cells associates with the activation/exhaustion status of memory T cells in chronic HIV type 1 infection.

Chronic HIV-1 infection is characterized by immune cell dysfunctions driven by chronic immune activation. Plasma HIV-1 viral load (VL) is closely correlated with disease progression and the level of immune activation. However, the mechanism by which the persistent presence of HIV-1 damages immune cells is still not fully understood.
