Two new and very similar species of the genus Xynobius Foerster, 1863 are described and illustrated, X. subparallelus Han & van Achterberg, sp. nov. from Japan (Honshu) and X. setosiscutum van Achterberg, sp. nov. from Norway. Three species are newly reported from Norway: Xynobius aciculatus (Thomson, 1895), X. comatus (Wesmael, 1835), and X. polyzonius (Wesmael, 1835). X. polyzonius (Wesmael, 1835) and X. sapporanus (Fischer, 1963) are new combinations. Identification keys to the Xynobius species known from Norway and Japan are added.

Background/ObjectivesMoving into a nursing home is often an unavoidable life event for older people living with dementia. It is associated with negative emotions and outcomes. Research capturing their perspectives is scarce. This study aims to identify how older people living with dementia perceive a potential life in a nursing home and to understand their (future) care wishes.Materials and methodsThis study is part of the European TRANS-SENIOR research network. The study followed a qualitative phenomenological methodology. Semi-structured interviews with 18 community-dwelling older people living with dementia were conducted between August 2018 and October 2019 (METCZ20180085). A stepwise interpretive phenomenological analysis was performed.ResultsThe majority of community-dwelling older people feared the idea of potentially moving to a nursing home. The participants associated a possible move with negative perceptions and emotions. Additionally, this study emphasized the importance of knowledge of current and past experiences with care when identifying the participant's wishes. They wanted to remain (a) individuals, who are (b) autonomous and have (c) social contacts if they would move to a nursing home.Discussion/ImplicationsThis study showed how past and current care experiences can educate/inform healthcare professionals on the future care wishes of older people living with dementia. The results indicated that listening to the wishes, and life stories of people living with dementia could be a way of identifying 'a suitable time' to suggest a move to a nursing home. This could improve the transitional care process and adjustment to living in a nursing home.

Purpose After acute hospital admission, patients with a hip fracture are frequently discharged to skilled nursing homes providing geriatric rehabilitation (GR). There are few evidence-based studies regarding specific treatment times and assessments during GR. This study aims to provide a description of care for hip fracture patients during GR in the Netherlands. Methods Descriptive study analyzing the care pathways from GR facilities, regarding healthcare professionals involved, allocated treatment time per profession, total length of rehabilitation stay, and assessment instruments. Based on the reimbursement algorithm (diagnostic treatment combination = DBCs), of 25 patients, the registered actual treatment time per profession was calculated. Results The care pathways pivoted on three groups of health care professionals: medical team (MT), physiotherapy (PT), and occupational therapy (OT). There was some discrepancy between the allocated time in the care pathways and the calculated mean actual treatment time from the DBCs. First week: MT 120–180 min, DBC 120 (SD: 59) minutes; PT 120–230 min, DBC 129 (SD: 58) minutes; and OT 65–165 min, DBC 93 (SD: 61) minutes. From week two onwards, MT 15–36 min, DBC 49 (SD: 29) minutes; PT 74–179 min, DBC 125 (SD: 50) minutes; and OT 25–60 min, DBC 47 (SD: 44) minutes. Dieticians, psychologists, and social workers were sporadically mentioned. There was heterogeneity in the assessment and screening tools. Conclusions It is difficult to define current standard care in GR after hip fracture in the Netherlands due to the diversity in care pathways and large practice variation. This is a problem in conducting randomized effectiveness research with care provided as control. Trial register and date of registration NL7491 04-02-2019.

Purpose: To assess the presence of upper extremity pain after stroke over time and the course of its intensity in patients with persistent pain. Materials and methods: Patients with stroke completed a question on the presence of upper extremity pain (yes/no) and rated its intensity with a visual analogue scale (0-10) at 3, 18, and 30 months after starting multidisciplinary rehabilitation. The presence of upper extremity pain and its intensity over time were analysed with Generalized Estimating Equations models and Linear Mixed Models, respectively. Results: 678 patients were included. The proportions of patients reporting upper extremity pain were 41.8, 36.0, and 32.7% at 3, 18, and 30 months, respectively, with the decline in proportions reaching statistical significance (odds ratio 0.82, 95% confidence interval 0.74-0.92, p < 0.001). At all time points, in those reporting pain the median intensity was 5.0 (interquartile ranges (IQR) 4.0-7.0 at 3 and 3.0-6.0 at 18 and 30 months). In the 73 patients with persistent pain, there was no significant change in intensity over time. Conclusions: The proportion of patients reporting upper extremity pain after stroke was considerable, despite a significant decrease in 2.5 years. In patients reporting persistent pain, the intensity did not change over time.

Background: Nursing home (NH) staff and residents have been prioritized to receive COVID-19 vaccinations. However, NH staff have been hesitant. This study explored what strategies were used to overcome this hesitancy and which of these were found to be important by NH staff to increase their willingness to take a COVID-19 vaccine. Methods: This study employed a sequential exploratory qualitative design. The COVID-19 MINUTES study aimed to describe the challenges presented by, responses to, and impact of the COVID-19 pandemic in NHs. The minutes of COVID-19 outbreak teams (COTs) in Dutch long-term care organizations (n = 41) were collected and coded using content analysis. Textual units from December 2020 to April 2021 that regarded strategies to increase staff’s vaccination willingness (n = 67) were selected. Subsequently, to validate these data, two panels of NH healthcare workers (HCWs) and policy workers (PWs) (n = 8) selected, discussed, and ranked the strategies that they found to be important using a modified nominal group technique. Results: The strategies described in the minutes included financial reimbursements, personal contact, story sharing, logistics support, role models, visual information, and written information. Except for financial reimbursement, all these strategies were considered important or very important by the panel participants. Some organizations combined multiple strategies. Conclusion: The strategies that were found important in combination may be used more broadly and should be developed further with the involvement of HCWs.

Coronavirus disease 2019 (COVID-19) poses a threat to the health and independence of older people in particular. In this article we elaborate on the content and importance of post-acute COVID-19 geriatric rehabilitation from a European perspective. We explain the geriatric rehabilitation paradox and how this can and should be solved. We also present what post-acute COVID-19 geriatric rehabilitation should entail. This might not only help us to develop better geriatric rehabilitation services, but it should also inform pandemic preparedness in the future.

The new species comes close to C. procarinator Ranjith & van Achterberg, 2018, sharing the posterior pits of scutellum separated by 0.5 × diameter of pit. But the new species can be separated from C. procarinator by the following differences: transverse posterior carina of propodeum arched and close to an additional transverse carina (transverse posterior carina rounded medially and without additional transverse carina in C. procarinator), shorter malar space than in C. procarinator; lateral depressions of metanotum smooth (crenulate in C. procarinator), first flagellomere 4.8 × as long as wide (4.1 × in C. procarinator), hind basitarsus 4.0 × as long as wide (4.5 × in C. procarinator) and OOL 1.8 × POL (2.2 × in C. procarinator). Based on the character of midlongitudinal carina of propodeum bifurcated posteriorly, the new species comes close to C. tihamica Ghramh & Ahmad, 2019 described from Saudi Arabia. However, the new species can be distinguished from the latter in having mesoscutum yellowish (blackish brown in C. tihamica), dorsal length of eye 2.0 × as long as temple (1.5 × in C. tihamica), scutellar sulcus without crenulae (with crenulae in C. tihamica), hind tibia 5.7 × as long as wide (7.0 × in C. tihamica) and first metasomal tergite 2.4 × as long as maximum width (4.0 × in C. tihamica).
