Reference values for Jamar+ digital dynamometer hand grip strength in healthy adults and in adults with non-communicable diseases or osteoarthritis: the Norwegian Tromsø study 2015–2016
Hand grip strength (HGS) is a key indicator of intrinsic capacity and has shown good predictive ability for morbidity and mortality. Reference values from normative populations are valuable, and such data from the Norwegian population are scarce. Normative values for the digital Jamar+ dynamometer are largely lacking. HGS was assessed in the Norwegian Tromsø study, survey 7 in 2015-2016 for 7824 participants (9324 invited) aged 40+ using a Jamar+ digital dynamometer, and three measurements for each hand were performed following the Southampton protocol. To account for non-response, full Tromsø population data, by age, education and sex, were collected from registry data from microdata.no, a service from Statistics Norway, and were then used as post-stratification weights, to provide standardized HGS values. HGS was higher in men than in women and inversely associated with age. Men and women with a history of non-communicable diseases had lower HGS than those without these conditions, while osteoarthritis was associated with lower HGS only among men. Lower height was associated with lower HGS, especially at younger ages in men. This article provides up-to-date references values for HGS in the community-dwelling population aged 40+ with or without osteoarthritis or non-communicable diseases, in Tromsø, Norway. These reference values will guide clinicians and researchers.

Mobility and associations with levels of cerebrospinal fluid amyloid β and tau in a memory clinic cohort
Background: Mobility impairments, in terms of gait and balance, are common in persons with dementia. To explore this relationship further, we examined the associations between mobility and cerebrospinal fluid (CSF) core biomarkers for Alzheimer’s disease (AD).
Methods: In this cross-sectional study, we included 64 participants [two with subjective cognitive decline (SCD), 13 with mild cognitive impairment (MCI) and 49 with dementia] from a memory clinic. Mobility was examined using gait speed, Mini-Balance Evaluation Systems test (Mini-BESTest), Timed Up and Go (TUG), and TUG dual-task cost (TUG DTC). The CSF biomarkers included were amyloid-β 42 (Aβ42), total-tau (t-tau), and phospho tau (p-tau181). Associations between mobility and biomarkers were analyzed through correlations and multiple linear regression analyses adjusted for (1) age, sex, and comorbidity, and (2) SCD/MCI vs. dementia.
Results: Aβ42 was significantly correlated with each of the mobility outcomes. In the adjusted multiple regression analyses, Aβ42 was significantly associated with Mini- BESTest and TUG in the fully adjusted model and with TUG DTC in step 1 of the adjusted model (adjusting for age, sex, and comorbidity). T-tau was only associated with TUG DTC in step 1 of the adjusted model. P-tau181 was not associated with any of the mobility outcomes in any of the analyses.
Conclusion: Better performance on mobility outcomes were associated with higher levels of CSF Aβ42. The association was strongest between Aβ42 and Mini-BESTest, suggesting that dynamic balance might be closely related with AD-specific pathology.

Hearing Loss, Hearing Aid Use, and Subjective Memory Complaints: Results of the HUNT Study in Norway
Objective: To study the association between hearing loss severity, hearing aid use, and subjective memory complaints in a large cross-sectional study in Norway.
Methods: Data were drawn from the fourth wave of the Trøndelag Health Study (HUNT4 Hearing, 2017–2019). Hearing threshold was defined as the pure tone average of 0.5, 1, 2 and 4 kHz in the better ear. The participants were divided into five groups: normal hearing or slight/mild/moderate/severe hearing loss. Subjective self-reported short-term and long-term memory complaints was measured by the nine-item Meta-Memory Questionnaire (MMQ). The sample included 20,092 individuals (11,675 women, mean age 58,3 years) who completed both hearing and MMQ tasks. Multivariate analysis of variance (adjusted for covariates of age, sex, education, and health cofounders) was used to evaluate the association between hearing status and hearing aid use (in the hearing-impaired groups) and long-term and short-term subjective memory complaints.
Results: Multivariate analysis of variance, followed by univariate ANOVA and pairwise comparisons showed that hearing loss was associated only with more long-term subjective memory complaints and not with short-term subjective memory complaints. In the hearing-impaired groups, the univariate main effect of hearing aid use was only observed for subjective long-term memory complaints and not for subjective short-term memory complaints. Similarly, the univariate interaction of hearing aid use and hearing status was significant for subjective long-term memory complaints and not for subjective short-term memory complaints. Pairwise comparisons, however, revealed no significant differences between hearing loss groups with respect to subjective long-term complaints.
Conclusion: This cross-sectional study indicates an association between hearing loss and subjective long-term memory complaints, but not with subjective short-term memory complaints. In addition, an interaction between hearing status and hearing aid use for subjective long-term memory complaints was observed in hearing-impaired groups, which calls for future research to examine the effects of hearing aid use on different memory systems.

Geriatric impairments are associated with reduced quality of life and physical function in older patients with cancer receiving radiotherapy – A prospective observational study
Quality of life (QoL) and function are important outcomes for older adults with cancer. We aimed to assess differences in trends in patient-reported outcomes (PROs) during radiotherapy (RT) between (1) groups with curative or palliative treatment intent and (2) groups defined according to the number of geriatric impairments.
Materials and Methods
A prospective observational study including patients aged ≥65 years receiving curative or palliative RT was conducted. Geriatric assessment (GA) was performed before RT, and cut-offs for impairments within each domain were defined. Patients were grouped according to the number of geriatric impairments: 0, 1, 2, 3, and ≥ 4. Our primary outcomes, global QoL and physical function (PF), were assessed by The European Organisation for Research and Treatment of Cancer Quality-of-Life Core Questionnaire (EORTC) (QLQ-C30) at baseline, RT completion, and two, eight, and sixteen weeks later. Differences in trends in outcomes between the groups were assessed by linear mixed models.
301 patients were enrolled, mean age was 73.6 years, 53.8% received curative RT. Patients receiving palliative RT reported significantly worse global QoL and PF compared to the curative group. The prevalence of 0, 1, 2, 3 and ≥ 4 geriatric impairments was 16.6%, 22.7%, 16.9%, 16.3% and 27.5%, respectively. Global QoL and PF gradually decreased with an increasing number of impairments. These group differences remained stable from baseline throughout follow-up without any clinically significant changes for any of the outcomes.
Increasing number of geriatric impairments had a profound negative impact on global QoL and PF, but no further decline was observed for any group or outcome, indicating that RT was mainly well tolerated. Thus, geriatric impairments per se should not be reasons for withholding RT. GA is key to identifying vulnerable patients in need of supportive measures, which may have the potential to improve treatment tolerance.
Fysisk funksjon hos eldre som går til fysioterapeut i Kongsberg kommune – en tverrsnittsundersøkelse
Hensikt: Kartlegge og sammenligne fysisk funksjon hos eldre personer som får fysioterapi hos avtalefysioterapeuter og fastlønnede fysioterapeuter. Beskrive karakteristika av behandlingen som blir gitt.
Materiale: 250 pasienter fra fysioterapitjenesten i Kongsberg kommune, 179 deltagere ble inkludert fra avtalefysioterapeuter og 71 fra fastlønnede fysioterapeuter.
Metode: Spørreskjema og fysiske tester (Short Physical Performance Battery og ganghastighet).
Resultat: Pasientene som mottar fysioterapi fra de fastlønnede fysioterapeutene har et lavere funksjonsnivå enn de de som mottar fysioterapi fra avtaleterapeutene. De er også eldre, har flere sykdommer og bruker flere offentlige tjenester.
Konklusjon: Kartleggingen av pasienter over 70 år som mottar fysioterapi i Kongsberg kommune viser at avtaleterapeuter og fastlønnede terapeuter følger opp ulike pasientgrupper, men at det hos begge grupper er en stor andel sårbare eldre med begrenset reservekapasitet.
