Effects of a Highly Portable Noninvasive Open Ventilation System on Activities of Daily Living in Patients with COPD.

For patients with chronic obstructive pulmonary disease (COPD), an increase in exercise tolerance and ability to perform activities of daily living (ADLs) can mean an improved quality of life with fewer exacerbations and lower health care expenses. We evaluated a wearable, noninvasive open ventilation (NIOV) system designed to enhance exercise capacity and increase mobility. Patients with stable, oxygen-dependent COPD were recruited for this prospective, open-label, crossover study.

Charlotte Wolff and lesbian history: reconfiguring liminality in exile.

This article considers the "liminality" of the psychologist Charlotte Wolff, MD (1897-1986). Always living openly as a lesbian since her school days in Danzig, Wolff trained as a doctor-also pursuing a parallel interest in poetry and in philosophy. As a Jewish person, she was forced to leave the Berlin Health Service and flee Germany when the Nazi regime came to power.

Magnus Hirschfeld, his biographies and the possibilities and boundaries of "biography" as "doing history.".

This article considers the two major biographies of sexologist Magnus Hirschfeld, MD (1868-1935), an early campaigner for "gay rights" avant la lettre. Like him, his first biographer Charlotte Wolff (1897-1986) was a Jewish doctor who lived and worked in Weimar Republic Berlin and fled Germany when the Nazi regime came to power. When researching Hirschfeld's biography (published in English in 1986) Wolff met a librarian and gay activist, Manfred Herzer, who would eventually be a cofounder of the Gay Museum in Berlin and publish (in German, in 1992) the other major Hirschfeld biography currently available.
