Gesundheit wohnungsloser Menschen während der COVID-19-Pandemie [Health of homeless individuals during the COVID-19 pandemic]
The living situation and health of homeless people differs from the general population in many ways. It is reasonable to assume that the homeless population has been particularly vulnerable during the coronavirus disease 2019 (COVID-19) pandemic. This narrative review will summarize the current literature on the health and care of homeless people during the COVID-19 pandemic. The literature research was performed between December 2022 and February 2023. In addition to the current national and international literature, findings from the "National Survey on the Psychiatric and Somatic Health of Homeless Individuals" (NAPSHI study) will be synopsized, examining psychiatric and somatic diseases as well as the care for homeless people in Germany. Homeless individuals are often mentally and physically ill and have limited access to the regular medical care system. Facilities with group rooms and dormitories pose a risk for outbreaks during the COVID-19 pandemic. As suspected, evidence of Severe Acute Respiratory Syndrome Coronavirus Type 2 (SARS-CoV‑2) infections emerged more frequently in homeless individuals than in the general population during the pandemic. Many of the infected individuals were asymptomatic. High rates of those unknowingly infected homeless individuals may have contributed to the spread of the viral disease. However, uncontrolled COVID-19 outbreaks, as feared by some researchers at the beginning of the pandemic, were not observed. Die Lebenssituation und die Gesundheit wohnungsloser Menschen unterscheiden sich in vielerlei Hinsicht von denen der Allgemeinbevölkerung. Die Vermutung liegt nahe, dass es sich bei wohnungslosen Menschen um eine besonders vulnerable Personengruppe während der Coronavirus-Disease-2019(COVID-19)-Pandemie handelt. In dieser narrativen Übersichtsarbeit soll die aktuelle Literatur zur Gesundheit und Versorgung von wohnungslosen Menschen während der COVID-19-Pandemie zusammengefasst werden. Recherchiert wurde zwischen Dezember 2022 und Februar 2023. Neben der aktuellen nationalen und internationalen Literatur sollen insbesondere die Ergebnisse des „National survey on psychiatric and somatic health of homeless individuals“ (NAPSHI-Studie) synoptisch dargestellt werden; diese untersucht psychische und somatische Erkrankungen sowie die Versorgung wohnungsloser Menschen in Deutschland. Wohnungslose Menschen sind häufig psychisch und somatisch erkrankt und haben einen eingeschränkten Zugang zum medizinischen Regelsystem. Versorgungseinrichtungen mit Gruppenräumen und Schlafsälen stellen ein Risiko für ein Ausbruchsgeschehen in der COVID-19-Pandemie dar. Wie vermutet, zeigten sich im Verlauf der Pandemie bei wohnungslosen Menschen häufiger als in der Allgemeinbevölkerung Hinweise für Severe Acute Respiratory Syndrome Coronavirus Type 2(SARS-CoV‑2)-Infektionen, viele davon schienen allerdings asymptomatisch zu verlaufen. Eine hohe Rate an unwissentlich infizierten wohnungslosen Menschen könnte zur Verbreitung der Viruserkrankung beigetragen haben. Trotzdem war ein unkontrolliertes COVID-19-Ausbruchsgeschehen, vor dem einige Wissenschaftler:innen zu Beginn der Pandemie warnten, nicht zu beobachten
Relationship between Lipoprotein (a) and cognitive function – Results from the Berlin Aging Study II
It has been suggested that an age-related loss of cognitive function might be driven by atherosclerotic effects associated with altered lipid patterns. However, the relationship between Lipoprotein (a) [Lp(a)] and healthy cognitive aging has not yet been sufficiently investigated. For the current analysis we used the cross-sectional data of 1,380 Berlin Aging Study II (BASE-II) participants aged 60 years and older (52.2% women, mean age 68 ± 4 years). We employed the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD)-Plus test battery to establish latent factors representing continuous measures of domain specific cognitive functions. Regression models adjusted for APOE genotypes, lipid parameters and other risk factors for cognitive impairment were applied to assess the association between Lp(a) and performance in specific cognitive domains. Men within the lowest Lp(a)-quintile showed better cognitive performance in the cognitive domain executive functions and processing speed (p = 0.027). No significant results were observed in women. The results of the current analysis of predominantly healthy BASE-II participants point towards an association between low Lp(a) concentrations and better cognitive performance. However, evidence for this relationship resulting from the current analysis and the employment of a differentiated cognitive assessment is rather weak
Virtual non-contrast reconstructions of photon-counting detector CT angiography datasets as substitutes for true non-contrast acquisitions in patients after EVAR—performance of a novel calcium-preserving reconstruction algorithm
The purpose of this study was to evaluate virtual-non contrast reconstructions of Photon-Counting Detector (PCD) CT-angiography datasets using a novel calcium-preserving algorithm (VNC(PC)) vs. the standard algorithm (VNC(Conv)) for their potential to replace unenhanced acquisitions (TNC) in patients after endovascular aneurysm repair (EVAR). 20 EVAR patients who had undergone CTA (unenhanced and arterial phase) on a novel PCD-CT were included. VNC(Conv)- and VNC(PC)-series were derived from CTA-datasets and intraluminal signal and noise compared. Three readers evaluated image quality, contrast removal, and removal of calcifications/stent parts and assessed all VNC-series for their suitability to replace TNC-series. Image noise was higher in VNC- than in TNC-series (18.6 ± 5.3 HU, 16.7 ± 7.1 HU, and 14.9 ± 7.1 HU for VNC(Conv)-, VNC(PC)-, and TNC-series, p = 0.006). Subjective image quality was substantially higher in VNC(PC)- than VNC(Conv)-series (4.2 ± 0.9 vs. 2.5 ± 0.6; p < 0.001). Aortic contrast removal was complete in all VNC-series. Unlike in VNC(Conv)-reconstructions, only minuscule parts of stents or calcifications were erroneously subtracted in VNC(PC)-reconstructions. Readers considered 95% of VNC(PC)-series fully or mostly suited to replace TNC-series; for VNC(Conv)-reconstructions, however, only 75% were considered mostly (and none fully) suited for TNC-replacement. VNC(PC)-reconstructions of PCD-CT-angiography datasets have excellent image quality with complete contrast removal and only minimal erroneous subtractions of stent parts/calcifications. They could replace TNC-series in almost all cases
Prevalence and Factors Associated with Fear of COVID-19 Among Homeless Individuals During the COVID-19 Pandemic: Evidence from the Hamburg Survey of Homeless Individuals.
PURPOSE: To clarify the prevalence and determinants of fear of COVID-19 among homeless individuals during the COVID-19 pandemic. PATIENTS AND METHODS: Data were taken from the Hamburg survey of homeless individuals (n=150) covering homeless adults in Hamburg, Germany. Multiple linear regressions were used. Beyond sociodemographic and lifestyle-related independent variables, COVID-19-related factors were also used as independent variables. RESULTS: In sum, 56.2% of homeless individuals reported no fear of COVID-19, 23.8% reported a little fear of COVID-19, 9.2% reported some fear of COVID-19 and 10.8% reported severe fear of COVID-19. Regressions showed that an increased fear of COVID-19 was significantly associated with younger age (β=-.01, p<0.05), absence of chronic alcohol consume (β=-.55, p<0.01), an increased perceived own risk of getting infected with the coronavirus one day (β=0.42, p<0.001) and a higher agreement that a diagnosis of the coronavirus would ruin his/her life (β=0.13, p<0.01). CONCLUSION: Given the poor hygienic conditions and their increased vulnerability, data surprisingly suggest a quite low fear of COVID-19 among homeless individuals. Efforts may be beneficial which contribute to thinking rationally about COVID-19 among homeless people, since low levels of fear of COVID-19 may contribute to careless behavior and can lead to super-spreading events
Loneliness among Homeless Individuals during the First Wave of the COVID-19 Pandemic.
The feeling of loneliness is a major public health concern associated with multiple somatic and psychiatric illnesses. Studies have shown increasing incidence of loneliness in the general population during the first wave of the COVID-19 pandemic. Homeless individuals are a particularly vulnerable group; however, little is known about loneliness among homeless individuals. We therefore aimed to examine the prevalence of loneliness among homeless individuals during the pandemic. Furthermore, we estimated the association between loneliness and sociodemographic and lifestyle factors, as well as the self-perceived risk of contracting COVID-19. Data from the Hamburg survey of homeless individuals were used, including 151 homeless individuals that were recruited in spring of 2020. Loneliness was measured by the 3- item version of the UCLA-3 Loneliness Scale. To summarize, 48.5% of the participants experienced loneliness. Multiple linear regressions showed increased loneliness to be associated with male gender (β = 1.07, p = 0.01), being single (β = 1.33, p = 0.00), originating from Germany (β = 1.48, p = 0.00), high frequency of sharing a sleeping space with more than three people (β = 0.42, p = 0.02) and a higher self-perceived risk of contracting COVID-19 (β = 0.41, p = 0.02). On the contrary, there was no association of loneliness with age, educational level, chronic alcohol consumption or frequently sharing a sleeping space. In conclusion, the magnitude of loneliness among homeless individuals during the pandemic was highlighted. Description of factors determining loneliness may help to identify homeless individuals at risk
Seroprevalence of arthropod-borne bacterial infections in homeless individuals in Hamburg in 2020
PURPOSE: The number of homeless people in Germany is steadily increasing. Due to their often precarious living conditions, this specific population may be increasingly exposed to ectoparasites that can transmit various pathogens. To assess the prevalence and thus the risk of such infections, we analyzed the seropositivity of rickettsiosis, Q fever, tularemia and bartonellosis in homeless individuals. METHODS: A total of 147 homeless adults from nine shelters in Hamburg, Germany, were included. The individuals underwent questionnaire-based interviewing, physical examination, and venous blood was drawn between May and June 2020. Blood samples were analyzed for antibodies against rickettsiae (Rickettsia typhi and R. conorii), Coxiella burnetii, Francisella tularensis and bartonellae. RESULTS AND CONCLUSION: A very low seroprevalence of R. typhi and F. tularensis infection was found (0-1%), while antibodies against R. conorii and C. burnetii were more common (7% each), followed by a relatively high seroprevalence of 14% for bartonellosis. Q fever seroprevalence was associated with the country of origin, whereas bartonellosis seroprevalence was associated with the duration of homelessness. Preventive measures targeting ectoparasites, especially body lice, should be put in place continuously
Expiratory Venous Volume and Arterial Tortuosity are Associated with Disease Severity and Mortality Risk in Patients with COPD: Results from COSYCONET
Fear of COVID-19 among homeless individuals in Germany in mid-2021.
AIMS: To investigate the prevalence and the correlates of fear of COVID-19 among homeless individuals. METHODS: We used data from the "national survey on psychiatric and somatic health of homeless individuals during the COVID-19 pandemic" (NAPSHI-study) which took place in several large cities in Germany in Mid-2021 (n = 666 in the analytical sample). Mean age equaled 43.3 years (SD: 12.1 years), ranging from 18 to 80 years. Multiple linear regressions were performed. RESULTS: In our study, 70.9% of the homeless individuals reported no fear of COVID-19. Furthermore, 14.0% reported a little fear of COVID-19, 8.4% reported some fear of COVID-19 and 6.7% reported severe fear of COVID-19. Multiple linear regressions revealed that fear of COVID-19 was higher among individuals aged 50-64 years (compared to individuals aged 18-29 years: β = 0.28, p < 0.05), among individuals with a higher perceived own risk of contracting the coronavirus 1 day (β = 0.28, p < 0.001) as well as among individuals with a higher agreement that a diagnosis of the coronavirus would ruin his/her life (β = 0.15, p < 0.001). CONCLUSIONS: Only a small proportion of homeless individuals reported fear of COVID-19 in mid-2021 in Germany. Such knowledge about the correlates of higher levels of fear of COVID-19 may be helpful for addressing certain risk groups (e.g., homeless individuals aged 50-64 years). In a further step, avoiding extraordinarily high levels of fear of COVID-19 may be beneficial to avoid irrational thinking and acting regarding COVID-19 in this group
Determinants of health-related quality of life (HRQoL) among homeless individuals during the COVID-19 pandemic
OBJECTIVE: Thus far, there is very limited knowledge regarding homeless individuals during the COVID-19 pandemic, particularly related to the health-related quality of life (HRQoL). Thus, our aim was to evaluate HRQoL and to clarify the determinants of HRQoL among homeless individuals during the COVID-19 pandemic in Germany. METHODS: Data were taken from the national survey on psychiatric and somatic health of homeless individuals during the COVID-19 pandemic-NAPSHI (n = 616). The established EQ-5D-5L was used to quantify problems in five health dimensions, and its visual analogue scale (EQ-VAS) was used to record self-rated health status. Sociodemographic factors were included in regression analysis. RESULTS: Pain/discomfort was the most frequently reported problem (45.3%), thereafter anxiety/depression (35.9%), mobility (25.4%), usual activities (18.5%) and self-care (11.4%). Average EQ-VAS score was 68.97 (SD: 23.83), and the mean EQ-5D-5L index was 0.85 (SD: 0.24). Regressions showed that higher age and having a health insurance were associated with several problem dimensions. Being married was associated with higher EQ-VAS scores. CONCLUSIONS: Overall, our study findings showed a quite high HRQoL among homeless individuals during the COVID-19 pandemic in Germany. Some important determinants of HRQoL were identified (e.g., age or marital status). Longitudinal studies are required to confirm our findings
