- Appetite lossianorexia of aging is a highly prevalent and burdensome geriatric syndrome that strongly impairs the quality of life of older adults. Loss of appetite is associated with several clinical conditions, including comorbidities and other geriatric syndromes, such as frailty. Despite its importance, appetite loss has been under-evaluated and, consequently, under-diagnosed and under-treated in routine clinical care. The International Conference on Frailty and Sarcopenia Research (ICFSR) Task Force met virtually on September 27th 2021 to debate issues related to appetite loss/anorexia of aging. In particular, topics related to the implementation and management of appetite loss in at-risk older adult populations, energy balance during aging, and the design of future clinical trials on this topic were discussed. Future actions in this field should focus on the systematic assessment of appetite in the care pathway of older people, such as the Integrated Care for Older People (ICOPE) program recommended by the World Health Organization. Moreover, clinical care should move from the assessment to the treatment of appetite loss/anorexia. Researchers continue to pursue their efforts to find out effective pharmacologic and non-pharmacologic interventions with a favorable risk/benefit ratio.

- Background: Selection bias is often inevitable in epidemiologic studies. It is not surprising that study conclusions based on participants’ health status are frequently questioned. Objective: This study aimed to assess whether the non-participants affected the characteristics of a general population of the very old people. Design, Setting and Participants: Prospective, cross-sectional (N=650, aged 85 years old) analysis and 1-year follow-up (n=273), in Linköping, Sweden. Measurements: We analysed data on health-related factors from a postal questionnaire, a home visit and a clinic visit at baseline and at the 1-year follow-up. We calculated the effect size to evaluate the degree of differences between the groups. Results: A greater proportion of non-participants resided in sheltered accommodation or nursing homes (participants vs non-response vs refusal, 11% vs 22% vs 40, P<0.001, φ=0.24). During the home visit or clinic visit, a higher proportion of dropouts reported mid-severe problems in EQ-5D domains (mobility and self-care) and limitations in personal activities of daily living, but the differences between participants and dropouts were very small (φ<0.2). No significant difference was found between the groups with regard to emergency room visits or hospital admissions, despite the fact that more participants than dropouts (φ=0.23) had multimorbidities (≥2 chronic diseases). Living in sheltered accommodation or a nursing home (odds ratio (OR), 2.8; 95% confidence interval (CI), 1.5-5), female gender (OR, 1.8; 95% CI, 1.1-3.1) and receiving more home visits in primary care (OR, 1.03; 95% CI, 1-1.06) contributed positively to drop out in the data collection stages over the study period. Conclusion: Non-participants were not considered to be a group with worse health. Mobility problems may influence very old people when considering further participation, which threatens attrition.

- Background: FGF23 has been associated with frailty and functional performance in older individuals, but the association to sarcopenia is unknown. Objectives: To investigate the association between FGF23, frailty, sarcopenia and fractures in older community dwelling women. Design: Prospective longitudinal cohort study. Setting: Malmö, Sweden. Participants: 995 75-year-old women, followed prospectively for ten years, with re-investigations after five (n=667) and ten (n=324) years. Measurements: C-terminal levels of FGF23 were measured and a frailty index of ‘deficits in health’ created. Sarcopenia was defined by low muscle mass and strength and “probable sarcopenia” by low muscle mass only. Incident fractures were continuously registered for 10-years. Based on tertiles of FGF23, odds ratio for frailty, sarcopenia and probable sarcopenia was investigated using logistic regression models adjusted for: eGFR, PTH, calcium, vitamin D and phosphate. Fracture-free survival during 10-year follow-up was depicted using Kaplan Meier curves. Results: While fracture-free survival did not differ between tertiles, women in the highest tertile of FGF23 had lower muscle strength and gait speed, and higher proportion with impaired mobility at baseline. At age 75, these women had higher odds of also being frail (ORadj 1.6 (95% CI 1.1–2.4)) and suffering from probable sarcopenia (ORadj 1.8 (95% CI 1.1–3.1)), but not sarcopenia. At follow-up the association between FGF23 and probable sarcopenia was not evident. While the association with frailty was attenuated at age 80 after adjustment (ORadj 1.6 (95% CI 1.0–2.5)), women in the highest tertile had higher odds of being frail at age 85 (ORadj 3.4 (95% CI 1.7–6.6)). Conclusions: FGF23 may be a promising clinical marker for muscle strength, functional performance, and frailty in older women, but not for future fragility fractures. Whether FGF23 is also associated with sarcopenia requires further investigation.

- Objectives: To study the prevalence and overlap between malnutrition, sarcopenia and frailty in a selected group of nursing home (NH) residents. Design Cross-sectional descriptive study. Setting: Nursing homes (NH).Participants: 92 residents taking part in an exercise and oral nutritional supplementation study; >75 years old, able to rise from a seated position, body mass index <= 30 kg/m(2)and not receiving protein-rich oral nutritional supplements.Measurements: The MNA-SF and Global Leadership Initiative on Malnutrition (GLIM) criteria were used for screening and diagnosis of malnutrition (moderate or severe), respectively. Sarcopenia risk was assessed by the SARC-F Questionnaire (0-10p; >= 4=increased risk), and for diagnosis the European Working Group of Sarcopenia in Older People (EWGSOP2) criteria was used. To screen for frailty the FRAIL Questionnaire (0-5p; 1-2p indicating pre-frailty, and >3p indicating frailty), was employed.Results: Average age was 86 years; 62% were women. MNA-SF showed that 30 (33%) people were at risk or malnourished. The GLIM criteria verified malnutrition in 16 (17%) subjects. One third (n=33) was at risk for sarcopenia by SARC-F. Twenty-seven (29%) subjects displayed confirmed sarcopenic according to EWGSOP2. Around 50% (n=47) was assessed as pre-frail or frail. Six people (7%) suffered from all three conditions. Another five (5%) of the residents were simultaneously malnourished and sarcopenic, but not frail, while frailty coexisted with sarcopenia in 10% (n=9) of non-malnourished residents. Twenty-nine (32%) residents were neither malnourished, sarcopenic nor frail.Conclusions: In a group of selected NH residents a majority was either (pre) frail (51%), sarcopenic (29%) or malnourished (17%). There were considerable overlaps between the three conditions.

Tidskriftsartikel (refereegranskat)abstract
- Background: Human aging is characterized by a chronic, low-grade inflammation suspected to contribute to reductions in skeletal muscle size, strength, and function. Inflammatory cytokines, such as interleukin-6 (IL-6), may play a role in the reduced skeletal muscle adaptive response seen in older individuals.Objectives: To investigate relationships between circulating IL-6, skeletal muscle health and exercise adaptation in mobility-limited older adults.Design: Randomized controlled trial.Setting: Exercise laboratory on the Health Sciences campus of an urban university.Participants: 99 mobility-limited (Short Physical Performance Battery (SPPB) <= 9) older adults.Intervention: 6-month structured physical activity with or without a protein and vitamin D nutritional supplement.Measurements: Circulating IL-6, skeletal muscle size, composition (percent normal density muscle tissue), strength, power, and specific force (strength/CSA) as well as physical function (gait speed, stair climb time, SPPB-score) were measured pre- and post-intervention.Results: At baseline, Spearman's correlations demonstrated an inverse relationship (P<0.05) between circulating IL-6 and thigh muscle composition (r = -0.201), strength (r = -0.311), power (r = -0.210), and specific force (r = -0.248), and positive association between IL-6 and stair climb time (r = 0.256; P<0.05). Although the training program did not affect circulating IL-6 levels (P=0.69), reductions in IL-6 were associated with gait speed improvements (r = -0.487; P<0.05) in "higher" IL-6 individuals (>1.36 pg/ml). Moreover, baseline IL-6 was inversely associated (P<0.05) with gains in appendicular lean mass and improvements in SPPB score (r = -0.211 and -0.237, respectively).Conclusions: These findings implicate age-related increases in circulating IL-6 as an important contributor to declines in skeletal muscle strength, quality, function, and training-mediated adaptation. Given the pervasive nature of inflammation among older adults, novel therapeutic strategies to reduce IL-6 as a means of preserving skeletal muscle health are enticing.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND OBJECTIVE: The study aimed to evaluate the predictive validity of the Brody self-report frailty index among older people. Design, setting and measurements: A longitudinal cohort study (2-years) conducted in Sweden, which included 1141 respondents, aged 65-103 years. Data were collected during 2011-2013 through a postal questionnaire with questions about demographic data, living conditions, self-reported health, ADL dependency (ADL-staircase) and frailty (the Brody frailty index).RESULTS: The total sample was comprised of 53 percent women and the mean age was 74.5 years (SD 7.0). The mean frailty index score at baseline was 0.12 and increased with higher age (rs= 0.819) as well as with increased ADL dependency (rs = 0.740). The analyses showed high percentage of correctly classified cases (97.1-98.2), high specificity (98.1-98.4) but low sensitivity (22.2-66.7).CONCLUSION: The self-report frailty index seems to be a valid measure of current frailty, but its predictive validity was found to be non-acceptable especially regarding the instrument's sensitivity. Such instrument can be useful to predict frailty and allocate resources in the care of older people.

Tidskriftsartikel (refereegranskat)abstract
- Background: Limited data are available on body composition (BC) and physical function in healthy adults >80 y, potentially hampering development of reference values. We aimed to study 1) BC and physical function and 2) changes in hand-grip strength over a 4-year period in a community dwelling elderly Swedish population.Methods: Apparently healthy, community-dwelling men (n=51) and women (n=51) aged >83y were measured by Sit to Stand-test, hand grip strength, body height, body weight and BC using a Bioimpedance Spectroscopy (Impedimed). The study was approved by the Regional Ethical Review Board in Gothenburg as an addition to Elderly Persons in the Risk Zone (T176-12).Results: Mean age 86.5 y, no age difference between sexes. Men and women performed equally well at the Sit to Stand-test. Men were significantly stronger with a mean HGS of 34.1 kg compared to women of 19.5 kg. 15 % had a BMI below 22 kg/m2. According to skeletal muscle index (SMI) 64 % were assessed as having severe sarcopenia (Cruz-Jentoft et al 2010).Conclusion: In this healthy elderly population BC and physical function was well preserved compared to previous studies, although many were classified as sarcopenic according to current cut-offs. Results from this study can be used as reference values for healthy community-dwelling elderly in high age.
