Detection of health deterioration in a COVID-19 patient at home: the potential of ambient sensor systems

The COVID-19 pandemic created increased interest in monitoring patients at home to allow timely recognition of health deteriorations. Hospital care is particularly demanding in these patients because of the necessity for isolation to avoid further spread of the disease. Therefore, home care is a preferred treatment setting for these patients. This is, to our knowledge, the first report indicating the potential of an affordable, contactless, and unobtrusive ambient sensor system for the detection of signs of health deterioration in a patient with COVID-19 by a caregiver from a distance. Prospective data acquisition and correlation of the data with clinical events were obtained from an 81-year-old senior with COVID-19 before and, in particular, over a period of 10 days prior to hospitalization. Clinical signs included weakness, increased respiration rate, sleep disturbances, and confusion. The visualization of a combination of this information on a dedicated dashboard allowed the caregiver to recognize a serious health deterioration that required a lifesaving hospitalization. The potential of such ambient sensor systems to detect signs of serious health deterioration in patients with COVID-19 opens new opportunities for use in asymptomatic or oligosymptomatic patients who live alone and are sent back to their homes for isolation in quarantine after diagnosis

Microcirculation abnormalities in patients with fibromyalgia – measured by capillary microscopy and laser fluxmetry

This unblinded preliminary case-control study was done to demonstrate functional and structural changes in the microcirculation of patients with primary fibromyalgia (FM). We studied 10 women (54.0 ± 3.7 years of age) with FM diagnosed in accordance with the classification criteria of the American College of Rheumatology, and controls in three groups (n = 10 in each group) – age-matched women who were healthy or who had rheumatoid arthritis or systemic scleroderma (SSc). All 40 subjects were tested within a 5-week period by the same investigators, using two noninvasive methods, laser fluxmetry and capillary microscopy. The FM patients were compared with the healthy controls (negative controls) and with rheumatoid arthritis patients and SSc patients (positive controls). FM patients had fewer capillaries in the nail fold (P < 0.001) and significantly more capillary dilatations (P < 0.05) and irregular formations (P < 0.01) than the healthy controls. Interestingly, the peripheral blood flow in FM patients was much less (P < 0.001) than in healthy controls but did not differ from that of SSc patients (P = 0.73). The data suggest that functional disturbances of microcirculation are present in FM patients and that morphological abnormalities may also influence their microcirculation

Mikro-Hörübungen und authentische Hörmaterialien : Impulse für eine alternative fremd- und zweitsprachliche Hörverstehensdidaktik und ihre Beforschung

Impulse für eine alternative fremd- und zweitsprachliche Hörverstehensdidaktik und ihre Beforschung, Online-Tagung am Fr. 26.2.2021 an der Universität Bamberg. Organisation: Prof. Dr. Gunther Dietz Professur für Deutsche Sprachwissenschaft / Deutsch als Fremdsprache Unter Schlagwörtern wie „Micro-Listening“ und „Bottom-up skills“ wird in der fremdsprachlichen Hör-(Seh-)Verstehensdidaktik seit geraumer Zeit eine Fokusverschiebung diskutiert – von den traditionellen (inhaltlich orientierten) „Fragen zum Text“ hin zu Aufgaben / Übungen, die stärker auf die Arbeit an der lautlichen Substanz des Gehörten abzielen. Damit tritt auch verstärkt die Forderung nach Nutzung authentischer Hörmaterialien in den Vordergrund. Der Tagungsband möchte relevante Fragestellungen hierzu aufgreifen und Impulse für eine Neuausrichtung im Bereich der fremdsprachlichen Hörverstehensdidaktik geben.Under buzzwords such as "micro-listening" and "bottom-up skills", a shift in focus has been discussed for some time in foreign language listening comprehension didactics - from the traditional (content-oriented) "questions about the text" to tasks/exercises that aim more strongly at working on the sound substance of what is heard. Thus, the demand for the use of authentic listening materials comes to the fore. The conference volume would like to take up relevant questions and give impulses for a new orientation in the area of foreign language listening comprehension didactic
