Detection of a COVID-19 cluster by universal SARS-CoV-2 testing in a geriatric hospital and implications for infection control management.

Hospital-level COVID-19 testing strategies may require rapid changes depending on the dynamics of local epidemiology. A COVID-19 outbreak in a hospital near the authors' institution, a Geriatric Medicine centre in Berlin, Germany, prompted the implementation of comprehensive SARS-CoV-2 testing. Serial nasopharyngeal swabs were collected from all patients and staff and analysed for SARS-CoV-2 virus RNA using quantitative real-time PCR.

[Patients with type-II diabetes mellitus and neuropathy have no deficiency of vitamins A, E, beta-carotene, B1, B2, B6, B12 and folic acid].

The present study was aimed to determine the vitamin status of vitamins A, E, beta-carotene, B1, B2, B6, B12 and folate in plasma using HPLC and vitamins B1, B2 and B6 in erythrocytes using the apoenzyme stimulation test with the Cobas-Bio analyzer in 29 elderly type II diabetic women with (G1: n = 17, age: 68.6 +/- 3.2 years) and without (G2: n = 12, age: 71.

Differential beta adrenergic sensitivity of atrial and ventricular tissue assessed by chronotropic, inotropic, and cyclic AMP responses to isoprenaline and dobutamine.

Cat atrial tissue was more sensitive to isoprenaline (USP:isoproterenol) and dobutamine than ventricular tissue. Chronotropic response of atrial strips occurred at lower agonist concentrations than inotropic responses of papillary muscle. Cyclic AMP responses in atrial slices also occurred at lower agonist concentrations and were of much greater magnitude than the cyclic AMP responses in ventricular slices.
