Calf circumference predicts sarcopenia in maintenance hemodialysis

BACKGROUND

Early recognition of sarcopenia in hemodialysis (HD) patients will be of great importance in preventing adverse outcomes and improving the quality of life in these patients. The main goal of this study was to evaluate the diagnostic accuracy of calf circumference (CC) measurement in detecting sarcopenia among CKD patients undergoing maintenance HD.

METHODS

This cross-sectional study included 52 patients (53 ± 17 years) who were currently in a maintenance HD. Muscle strength was evaluated using handgrip strength, and smooth muscle mass index (SMI) was assessed through bioelectrical impedance analysis, and CC was measured at the widest part of the calf with the foot pressed against a hard surface.

RESULTS

Out of the total patient population, sarcopenia was identified in 32.7% (n = 17). The two groups were comparable in terms of age, weight, and height, but the median body mass index of sarcopenic group was statistically lower than nonsarcopenic group (21.6 kg/m2 [18.9-24.6] vs 24.7 kg/m2 [21.4-27.3]. The sarcopenic group had a substantially smaller CC than the nonsarcopenic group (30.0 cm [26.5-32.0] vs 31.5 cm [30.3-34.8], P = 0.013; respectively). In the regression analysis, CC was found to be independently associated with post-HD SMI (P < 0.001; odds ratio, 1.938; and 95% CI, 1.020-2.856). CC was positively but weakly correlated with handgrip strength, however strong and significant correlation was found between CC and SMI (r = 0.277, P = 0.047 and r = 0.733, P < 0.001; respectively). A CC of 31 cm or less predicted confirmed sarcopenia in HD patients (area under the curve = 0.709, P = 0.006, specificity = 0.556, sensitivity = 0.765).

CONCLUSIONS

Low muscle mass and potentially low muscle strength in HD patients can be accurately identified through the use of CC measurements. Specifically, a CC measurement below 31 cm has found to be a useful indicator to identify individuals on maintenance HD.

Association between decreased neck circumference and impaired activities of daily living among older adults in long-term care

AIM

Assessment interventions for the decline of activities of daily living (ADLs) in older adults are crucial, as ADL decline increases hospitalization duration and mortality risk. Decreased neck circumference may result in various physical dysfunctions, including malnutrition. However, the association between neck circumference and ADLs has not been fully clarified. This study aimed to determine the association between decreased neck circumference and ADLs in older adults requiring long-term care.

METHODS

The study included 152 older adults deemed to require support or care under Japan's long-term care insurance system. Neck circumference was measured just below the thyroid cartilage with a measuring tape. The Barthel index was used to evaluate ADLs, and skeletal muscle mass and nutritional status were assessed by bioelectrical impedance analysis instruments. A multivariate analysis was conducted to investigate the association between neck circumference and ADLs.

RESULTS

Neck circumference demonstrated a significant inverse correlation with age and a significant positive correlation with body mass index, skeletal muscle mass index, phase angle, and Barthel index. In the multivariate analysis, ADLs was significantly associated with neck circumference (odds ratio [OR] = 0.51, P = 0.002) and phase angle (OR = 0.04, P < 0.001).

CONCLUSIONS

Neck circumference is associated with age, skeletal muscle mass, and nutritional status. Furthermore, a decrease in neck circumference is suggested as an independent risk factor for ADL decline in older adults requiring long-term care. Geriatr Gerontol Int 2023; 23: 906-911.

Association between Malnutrition Assessed by the Global Leadership Initiative on Malnutrition Criteria and Mortality in Older People: A Scoping Review

The Global Leadership Initiative on Malnutrition (GLIM) criteria were introduced in 2018 for the diagnosis of malnutrition in adults. This review was aimed at gathering the evidence about the association between malnutrition according to the GLIM criteria and mortality in older people, an emerging and clinically meaningful topic in the implementation of the GLIM criteria in geriatric healthcare settings. This scoping review considered meta-analyses, systematic reviews, cohort studies, and cross-sectional studies published in PubMed, Scopus, and the Cochrane Database for Systematic Reviews from the development of the GLIM criteria in 2018 to January 2023. Seventeen articles (15 cohort and 2 cross-sectional studies) were included. The association between GLIM criteria and mortality had been assessed in hospitalized (11 over the 17 articles) and community-dwelling older populations, and those in nursing homes. The review found a strong association between malnutrition according to GLIM criteria and mortality in hospitalized (1.2-fold to 7-fold higher mortality) and community-dwelling older people (1.6-fold to 4-fold higher mortality). These findings highlight the prognostic value of the GLIM criteria and support strategies towards the implementation of malnutrition evaluation according to the GLIM, in order to optimize comprehensive geriatric assessment and provide older people with the highest quality of nutritional care. Studies in nursing home populations were very scarce and may be urgently required.

Malnutrition in older adults

Malnutrition is a highly prevalent condition in older adults, and poses a substantial burden on health, social, and aged-care systems. Older adults are vulnerable to malnutrition due to age-related physiological decline, reduced access to nutritious food, and comorbidity. Clinical guidelines recommend routine screening for malnutrition in all older adults, together with nutritional assessment and individually tailored nutritional support for older adults with a positive screening test. Nutritional support includes offering individualised nutritional advice and counselling; oral nutritional supplements; fortified foods; and enteral or parenteral nutrition as required. However, in clinical practice, the incorporation of nutritional guidelines is inadequate and low-value care is commonplace. This Review discusses the current evidence on identification and treatment of malnutrition in older adults, identifies gaps between evidence and practice in clinical care, and offers practical strategies to translate evidence-based knowledge into improved nutritional care. We also provide an overview of the prevalence, causes, and risk factors of malnutrition in older adults across health-care settings.

Indicators predicting the development and improvement of sarcopenia in older adults requiring long-term care

[Purpose] This study aimed to identify factors associated with sarcopenia development and improvement among older adults requiring long-term care. [Participants and Methods] This prospective observational study included 118 older adults requiring long-term care in a single facility. Sarcopenia was assessed according to the 2019 diagnostic criteria of the Asian Working Group for Sarcopenia at baseline and after 6 months. Nutritional status was measured using calf circumference and the Mini Nutritional Assessment-Short Form to examine the association between sarcopenia onset and improvement. [Results] Risk of malnutrition and lower calf circumference at baseline were significantly associated with sarcopenia development. The study also showed that a non-risk of malnutrition, higher calf circumference, and higher skeletal muscle mass index were significantly associated with improved sarcopenia. [Conclusion] The Mini Nutritional Assessment-Short Form and calf circumference were able to predict sarcopenia development and improvement in older adults requiring long-term care.

Efficacy of Global Leadership Initiative on Malnutrition as potential cachexia screening tool for patients with solid cancer

PURPOSE

Cachexia has a very high prevalence in patients with cancer, and lacks effective screening tools yet. Global Leadership Initiative on Malnutrition (GLIM) is a novel malnutrition assessment tool, with increased important roles in malnutrition diagnosis for patients with cancer. However, whether GLIM can be used as an effective screening tool remains unknown.

METHODS

We performed a multicenter cohort study including 8,478 solid tumor patients from 40 clinical centers throughout China. Cachexia was diagnosed based on the 2011 international cancer cachexia consensus. The receiver operating characteristic curves (ROC) and decision curve analysis (DCA) were developed to determine the efficacy and clinical net benefit of GLIM and Patient-Generated Subjective Global Assessment (PG-SGA) in the detection of cancer cachexia, respectively.

RESULTS

According to the consensus guidelines, 1,441 (17.0%) cancer patients were diagnosed with cachexia among 8,478 patients in the present study. The sensitivity of one-step GLIM and two-step GLIM for detecting cachexia were 100 and 88.8%, respectively, while that of PG-SGA was 86.2%. The accuracies of one-step GLIM and two-step GLIM reached 67.4 and 91.3%, which were higher than that of PG-SGA (63.1%). The area under the curves (AUCs) of one-step GLIM (0.835) and two-step GLIM (0.910) were higher than PG-SGA (0.778) in patients with cancer. The DCA also revealed that two-step GLIM had better clinical effect than PG-SGA between 20-50% threshold probabilities.

CONCLUSION

GLIM could be used as an effective tool in screening cancer cachexia, two-step GLIM criteria show more accurate while one-step GLIM criteria is more sensitive.

Comparing the validity of anthropometric measurements in identifying malnutrition status of older age people in Borena district, North Central Ethiopia: a cross_sectional study

Background

Malnutrition among older age people is becoming significantly higher in spite of improvements in the health care system. Life expectancy of Ethiopian elders is increasing; but reliable and valid tools for screening and diagnosis of malnutrition in this subgroup are limited. This study aimed to assess the validity of anthropometric measurements: Mid Upper Arm Circumference (MUAC), Body Mass Index (BMI), and Calf Circumference (CC) in detecting malnutrition status of older age people in Ethiopia.

Methods

A community based cross-sectional study was conducted in Borena District from January to March, 2020. A total of 421 participants aged were systematically included in the study. To test reliability and validity of the measurements,Cronbach’s α coefficient and Pearson’s correlations were used, respectively. The full Mini-Nutritional Assessment (MNA) tool was used to diagnosis malnutrition. Overall accuracy, sensitivity and specificity of BMI, MUAC and CC were estimated using Receiver Operating Characteristic curves. The Youden Index was used to determine the best cut-off point.

Results

The reliability of BMI, MUAC and CC by Cronbach’s alpha was found 0.847. Significant positive correlations between MNA, BMI(r = 0.56, p < 0.01); MNA, MUAC(r = 0.43, p < 0.01; and MNA, CC(r = 0.52, p < 0.01) revealed. The area under the curve (AUC) of BMI, MUAC and CC were found: 0.98(95% CI, 0.96–0.99, p < 0.001), 0.94(95% CI, 0.89–0.98, p < 0.001) and 0.96(95% CI, 0.94–0.98, p < 0.001) indicating the overall accuracy respectively. The sensitivity and specificity of BMI, MUAC and CC using established cut off points were found: 90%, 96%; 78%, 94% and 84%, 95% respectively. However, using the Youden index the best cut-off point, the sensitivity and specificity of MUAC and CC were 88%, 86%; 92% and 89% respectively and adjusted for age and sex.

Conclusions

The current study demonstrated that BMI was a reliable and valid method to identify the malnutrition status of older age people. A MUAC value of 19 cm and CC of 30 cm were simple and efficient cut-off points for the determination of malnutrition in the older age people. A future study is needed to validate the validity of BMI, MUAC and CC against biochemical tests as gold standard.

Mini Nutritional Assessment and physical function of older people in residential aged care facility, Bangladesh

BACKGROUND

Malnutrition may decrease physical function and exacerbate health conditions and thus have a negative effect on health-related quality of life of older people.

AIM

The study was aimed at evaluating the extent of malnutrition, physical function and other associated risk factors for the older persons (>65 years) living in the residential aged care facilities in Bangladesh.

METHODS

A cross-sectional study was performed with a sample of 200 older people in various residential aged care facilities in Dhaka, Bangladesh. Nutritional status was evaluated using the Mini Nutritional Assessment. A structured questionnaire was used to assess the socioeconomic condition, dietary diversity, functional ability and other related risk factors for malnutrition.

RESULTS

According to the Mini Nutritional Assessment, 33.5% of participants living in residential aged care facilities were malnourished and 52.5% were at risk of malnutrition. Dietary diversity score differs significantly (p<0.001) among malnourished (3.78 ± 0.45), at risk of malnutrition (4.46 ± 0.98) and well-nourished (4.75 ± 1.11) groups. Twenty-five percent of the study participants reported limitations in mobility and 26.5% reported limitations in activities of daily living. Females were more vulnerable in terms of malnutrition and physical function than males. Mini Nutritional Assessment score is significantly correlated (p<0.05) with several risk factors for malnutrition such as body mass index, education level, meal, protein consumption, dietary diversity score, weight loss, reduced food intake, mobility and activities of daily living of the older people.

CONCLUSIONS

The study reaffirms that a high rate of malnutrition and risk of malnutrition is prevalent among aged care residents, who need special attention and may benefit from individualized nutrition interventions.

Results of High-Protein, High-Calorie Oral Nutritional Supplementation in Malnourished Older People in Nursing Homes: An Observational, Multicenter, Prospective, Pragmatic Study (PROT-e-GER)

OBJECTIVES

To assess if the impact of oral nutritional supplements (ONS) on nutritional and functional status in malnourished older persons living in nursing homes shown by clinical trials are also found outside a trial setting.

DESIGN

Observational, multicenter, prospective, pragmatic study.

SETTING AND PARTICIPANTS

This study was carried out in 38 nursing homes throughout Spain. Nursing home physicians recruited consecutive residents, older than 65 years, with a diagnosis of malnutrition, when a clinical decision to start ONS had been taken after unsuccessful initial management with dietary interventions.

INTERVENTION

The participants received daily 2 bottles of an energy-rich, high-protein commercial ONS for 3 months.

MEASURES

Primary outcomes were changes in nutritional status [body weight, body mass index (BMI), and Mini Nutritional Assessment-Short Form (MNA-SF)]; secondary outcomes were functional changes [Functional Ambulation Classification, Barthel index, handgrip strength, and Short Physical Performance Battery (SPPB)], as well as safety and adherence after 12 weeks of follow-up.

RESULTS

A total of 282 residents (median age 86 years, 67% women) were included, and 244 (86.5%) completed the follow-up. At baseline, 77.3% of the participants were malnourished (BMI 19.7 kg/m², interquartile range 18.3-21.8). After 12 weeks of follow-up, participants experienced significant increases in body weight (2.6 ± 3.1 kg, 5.2 ± 5.9%), BMI (1.0 ± 1.2 kg/m²) and MNA-SF (4.0 ± 2.5 points). There were also significant improvements in functional status measured by the Barthel index, handgrip strength, SPPB, and gait speed. Good adherence was registered in 94.6% of the participants. No relevant side effects were found.

CONCLUSIONS AND IMPLICATIONS

Improvements in nutritional and functional status can be found when using a high-protein, high-calorie ONS in older undernourished people living in nursing homes.

Nutritional Assessment in Older Adults : MNA® 25 years of a Screening Tool and a Reference Standard for Care and Research; What Next?

A tool to assess nutritional status in older persons was really needed. It took 5 years to design the MNA® (Mini Nutrition Assessment) tool, complete the first validations studies both in Europe and in the U.S. and to publish it. After the full MNA®, the MNA® short form and the self-MNA® have been validated. As well as Chinese and other national MNA® forms. Now more than 2000 clinical research have used the MNA® all over the world from community care to hospital. At least 22 Expert groups included the MNA® in new clinical practice guidelines, national or international registries. The MNA® is presently included in almost all geriatric and nutrition textbook and part of the teaching program for medicine and other health care professional worldwide. The urgent need is to target the frail older adults more likely to have weight loss and poor appetite and to prevent frailty and weight loss in the robust. We present in this paper the review of 25 years of clinical research and practice using the MNA® worldwide.

Prediction of 5-year mortality risk by malnutrition according to the GLIM format using seven pragmatic approaches to define the criterion of loss of muscle mass

OBJECTIVES

To assess the association between baseline malnutrition according to the GLIM format, using seven pragmatic approaches to define the criterion of loss of muscle mass, with mortality in the SarcoPhAge (Sarcopenia and Physical Impairment with advancing Age) study during a 5-year follow-up. Secondarily, to calculate diagnostic performance indicators, concordance, and feasibility of these 7 pragmatic approaches compared to the original GLIM criteria.

METHODS

Post-hoc analysis of the SarcoPhAge cohort, which included 534 community-dwelling volunteers ≥65-year-old, followed-up from 2013 to 2019. Baseline malnutrition was defined by GLIM criteria and 7 approaches: 1) Omission of a reduced muscle mass as a criterion; 2) Substitution for handgrip strength, 3) Calf-circumference, 4) Mid-arm circumference, 5) Goodman's grid, 6) Ishii's score chart, and 7) Yu's formula. The association between malnutrition (according to GLIM criteria and the 7 approaches) and mortality was assessed by Cox-regressions. Sensitivity, Specificity, Positive (PPV), Negative (NPV) predictive values, area under the curve (AUC), Cohen-kappa coefficient, and TELOS-feasibility score were calculated.

RESULTS

Data to calculate GLIM criteria were available for 373 subjects (73.07 ± 5.96 years, 56% women). Prevalence of malnutrition with GLIM criteria was 24.4% (ranged from 13.9% to 20.9% with the 7 approaches). GLIM criteria showed a HR = 3.38 (1.89-6.09) to predict mortality during the 5-year follow-up, which ranged from HR = 2.72 (1.51-4.91) to 3.94 (2.14-7.24) with the 7 approaches. All 7 approaches were feasible (TELOS ≥ 3), showed sensitivity ≥ 65%, specificity ≥ 95.4%, PPV ≥ 85%, NPV ≥ 88%, AUC ≥ 0.7 and had almost-perfect/strong concordance (k ≥ 0.7) with the original GLIM criteria.

CONCLUSIONS

GLIM criteria and the 7 approaches predicted three-to four-fold mortality, all ensured an accurate diagnosis, and were feasible in clinical settings.
