Background: The COVID-19 pandemic is challenging healthcare systems worldwide. This study examines geriatric patients with proximal femur fractures during the COVID-19 pandemic, shifts in secondary disease profile, the impact of the pandemic on hospitalization and further treatment. Methods: In a retrospective monocentric study, geriatric proximal femur fractures treated in the first six months of 2020 were analyzed and compared with the same period of 2019. Pre-traumatic status (living in a care home, under supervision of a legal guardian), type of trauma, accident mechanism, geriatric risk factors, associated comorbidities, time between hospitalization and surgery, inpatient time and post-operative further treatment of 2 groups of patients, aged 65-80 years (Group 1) and 80+ years (Group 2) were investigated. Results: The total number of patients decreased (70 in 2019 vs. 58 in 2020), mostly in Group 1 (25 vs. 16) while the numbers in Group 2 remained almost constant (45 vs. 42). The percentage of patients with pre-existing neurological conditions rose in 2020. This corresponded to an increase in patients under legal supervision (29.3%) and receiving pre-traumatic care in a nursing home (14.7%). Fractures were mostly caused by minor trauma in a home environment. In 2020, total number of inpatient days for Group 2 was lower compared to Group 1 (p = 0.008). Further care differed between the years: fewer Group 1 patients were discharged to geriatric therapy (69.6% vs. 25.0%), whereas in Group 2 the number of patients discharged to a nursing home increased. Conclusions: Falling by elderly patients is correlated to geriatric comorbidities, consequently there was no change in the case numbers in this age group. Strategic measures to avoid COVID-19 infection in hospital setting could include reducing the length of hospital stays by transferring elderly patients to a nursing home as soon as possible and discharging independent, mobile patients to return home.

While load of inertial resistance directly affects the magnitude of the transient blood pressure reduction and heart rate response to active standing, blood pressure stabilization is most rapidly attained during terrestrial +G. The observation might suggest that the human cardiovascular system is tuned to cope with orthostatic stress on earth.

healthy subjects in the standing position while they were in parabolic flight at 0 and 1.8 g z . Plasma volume (PV) and fluid regulating blood hormones were determined five times over the flight day. Eleven out of the 18 subjects were subjected to an identical test protocol in a hypobaric chamber in ambient conditions comparable to parabolic flight. Results cI rb in 0 g z decreased significantly during flight (early, 5.139 ± 1.326 l/min; late, 4.150 ± 1.082 l/ min) because of a significant decrease in heart rate (Hr) (early, 92 ± 15 min −1 ; late, 78 ± 12 min −1), even though the stroke volume (SV) remained the same. HH produced a small decrease in the PV, both in the hypobaric chamber and in parabolic flight, indicating a dominating HH effect without a significant effect of gt on PV (−52 ± 34 and −115 ± 32 ml, respectively). Pulmonary tissue volume decreased in the HH conditions because of hypoxic pulmonary vasoconstriction (0.694 ± 0.185 and 0.560 ± 0.207 ml) but increased at 0 and 1.8 g z in parabolic flight (0.593 ± 0.181 and 0.885 ± 0.458 ml, respectively), indicating that cardiac output and arterial blood pressure rather than HH are the main factors affecting pulmonary vascular regulation in parabolic flight. Conclusion HH and gt each lead to specific responses of the cardiovascular system in parabolic flight. Whereas HH seems to be mainly responsible for the PV decrease in flight, gt overrides the hypoxic pulmonary vasoconstriction induced by HH. this finding indicates the need for careful and individual medical examination and, if necessary, health status improvement for each individual considering a parabolic flight, given the effects of the combination of HH and gt in flight.Keywords Inert gas rebreathing · Weightlessness · Hypobaric hypoxia · Hypobaric chamber · gravity AbstractPurpose commercial parabolic flights accessible to customers with a wide range of health states will become more prevalent in the near future because of a growing private space flight sector. However, parabolic flights present the passengers' cardiovascular system with a combination of stressors, including a moderately hypobaric hypoxic ambient environment (HH) and repeated gravity transitions (gt). thus, the aim of this study was to identify unique and combined effects of HH and gt on the human cardiovascular, pulmonary and fluid regulation systems. Methods cardiac index was determined by inert gas rebreathing (cI rb ), and continuous non-invasive finger blood pressure (FBP) was repeatedly measured in 18 communicated by guido Ferretti.Electronic supplementary material the online version of this article

ZusammenfassungSeit Auftreten der neuen Coronavirus (COVID-19) Pandemie im März 2020 erkrankten viele Menschen in Deutschland. Dies bedeutete eine Herausforderung für die Versorgung psychisch kranker stationärer Personen. Es kam zu einem sozialen Shut-down in Bayern mit Abnahme der sozialen Kontakte. Die vorliegende Studie beschäftigt sich mit der Umsetzung der stationären psychiatrischen Versorgung durch Psychologen und Psychiater im homeoffice und in der Klinik. Psychologen der Klinik für Psychiatrie und Psychotherapie der LMU München etablierten in der akuten Krise im homeoffice während der Quarantäne zusammen mit den in der Klinik tätigen Ärzten eine telefonische Patientenversorgung für stationäre Patienten, an der 23 Patienten mit depressiven und schizophrenen Störungen teilnahmen. Die Psychologen arbeiteten danach im stationären Setting mit 98 Teilnehmern. Die derzeitige Notlage und ihre Belastungen werden thematisiert und neue therapeutische Komponenten in die Versorgung integriert. Die Umsetzbarkeit von homeoffice, deren Möglichkeiten und Grenzen werden vorgestellt. Konzepte der stationären Patientenversorgung für Betroffene mit affektiven und schizophrenen Störungen sowie aktuelle Belastungsfaktoren und psychotherapeutische Konzepte werden thematisiert. Der aktuelle Ansatz wird von den Betroffenen und Ärzten positiv bewertet und bietet gute Möglichkeiten in der derzeitigen Situation. Mit Ausnahme der Patienten von der Akutstation konnten alle Patienten und selbst ältere von dieser Maßnahme profitieren. Während der Krise von März bis August arbeiteten alle Psychologen auf Ganztagsstellen mit der üblichen Behandlungsfrequenz von 1–2 Sitzungen die Woche, was insbesondere für ältere Personen von Bedeutung war. Während der akuten COVID-19 Krise pausierten lediglich stationsübergreifende Gruppen und Angehörigengruppen. Die Psychologen hatten wie die Ärzte und das Pflegepersonal eine systemrelevante Aufgabe.
