Mini Nutritional Assessment (MNA) is Rather a Reliable and Valid Instrument to Assess Nutritional Status in Iranian Healthy Adults and Elderly with a Chronic Disease

The relationship between depression and nutritional status among the elderly adults with cardiovascular diseases in Northern Iran

BACKGROUND

Malnutrition and depression among the elderly people with cardiovascular diseases are important public health concerns. This study made an attempt to determine the relationship between these people's depression and their nutritional status in northern Iran.

METHODS

This analytical cross-sectional study was conducted on 190 elderly patients hospitalized with cardiovascular diseases in Dr. Heshmat Heart Hospital in Rasht (Iran) in the 2022-2023. The research instruments included demographic information questionnaire, mini-nutritional assessment questionnaire, and geriatric depression scale. Data were analyzed by SPSS-21 software and using Chi-Square tests and ordinal logistic regression.

RESULTS

The participants' mean age was 68.4 ± 6.5 and 50.5% of the participants were women.56.3% of the elderly participants suffered from malnutrition and 96.3% of them suffered from various degrees of depression. Additionally, there was a relationship between the participants' severity of depression and their nutritional status. Significant relationships were also observed between the participants' depression (OR = 1.28 and p < 0.001), marital status (OR = 1.52 and p = 0.006), and underlying diseases (OR = 0.814, p = 0.035) with nutritional status.

CONCLUSION

Given the significant relationship depression with nutritional status in cardiovascular patients, early diagnosis and treatment of depression in these patients is essential to prevent the effects of depression on nutritional status and disease course.

The effect of Sarcomeal® oral supplementation plus vitamin D3 on muscle parameters and metabolic factors in diabetic sarcopenia patients: study protocol of a randomized controlled clinical trial

BACKGROUND

Diabetes is a significant risk factor for sarcopenia, a muscle dystrophy affecting older individuals. Sarcopenia management typically involves resistance exercise and oral supplements. Given the limitations of resistance training for many elderly individuals, oral supplements play a crucial role in treatment. This study is a protocol for evaluating the efficacy of the Sarcomeal® supplement, a mixture of whey protein, creatine, branch-chained amino acids (BCAAs), glutamine, and hydroxyl-methyl-butyrate (HMB) in diabetic people who also have sarcopenia. METHODS AND ANALYSIS: This study is a randomized clinical trial, in which sixty diabetic sarcopenia patients who meet the inclusion criteria will be randomly assigned to the control or the intervention group with a 1:1 allocation. The intervention group will receive one Sarcomeal® supplement sachet plus 1000 IU of vitamin D daily and both groups will be recommended to consume protein-rich food, be educated about the disease, and perform light exercises for 12 weeks. Anthropometric measurements, body composition analysis, muscle strength assessments, and blood tests will be conducted at the trial's start and end.

DISCUSSION

It is hypothesized that the Sarcomeal® supplement plus vitamin D may be beneficial for the management of diabetic sarcopenia by reducing inflammation, oxidative stress, and glucose metabolism. The outcome of this trial will provide a basis for prescribing sarcomeal to patients with diabetic sarcopenia.

ETHICS AND DISSEMINATION

This protocol is registered at the Iranian Registry of Clinical Trials (IRCT20230831059311N1) and also is approved by the ethics committee of Tehran University of Medical Sciences (September 2023, IR.TUMS.EMRI.REC.1402.071).

The ability of GLIM and MNA-FF to diagnose malnutrition and predict sarcopenia and frailty in hospitalized adults over 60 years of age

Introduction

Malnutrition remains common in adults over 60 years old. Although there are screening and diagnostic tools for malnutrition, there is no globally used approach to diagnosing malnutrition in older adults admitted to the hospital. In this study, we verified the agreement between the Global Leadership Initiative on Malnutrition (GLIM) and the Mini Nutritional Assessment (MNA) and the ability of the instruments to identify frailty and sarcopenia associated with malnutrition.

Methods

For adults over 60 years old, malnutrition diagnosis was performed using the Mini Nutritional Assessment Full Form (MNA-FF) tool and the GLIM criteria, which included calf circumference and fat-free mass index to assess muscle mass, with and without the Mini Nutritional Assessment Short Form (MNA-SF) screening. Health conditions were assessed in older adults, and the association of these conditions with malnutrition was analyzed using both tools.

Results

A total of 432 adults over 60 years old were investigated with a mean age of 71.14 ± 8 years. The GLIM criteria with the nutritional screening tool identified 61-63% of older adults as malnourished. Of these, 63-64% were severely malnourished. The MNA-FF tool classified 20% of those assessed as malnourished. The agreement between the MNA-FF and GLIM was better with the use of screening, with a kappa (K) value of -0.10 and - 0.11. Sarcopenia was associated with malnutrition as identified by the MNA-FF (OR: 3.08, 95% CI: 1.84-5.14) and only by the GLIM ANTHRO (OR: 1.66, 95% CI: 1.05-2.63). Frailty was associated with the MNA-FF (OR: 15.99, 95% CI: 2.16-118.36), GLIM ANTHRO (OR: 2.21, 95% CI: 1.31-3.71), and GLIM BIA (OR: 2.45, 95% CI: 1.45-4.12).

Conclusion

It is possible to verify that divergent conceptual frameworks are used to understand malnutrition by the MNA-FF and GLIM and that the GLIM obtained a greater number of malnutrition diagnoses. Both the GLIM ANTHRO and the MNA-FF associated malnutrition with frailty and sarcopenia, with higher hazard ratios for the MNA-FF.

Sarcopenia and Associated Factors in Adults Aged 40 and Above: A Study Conducted in Primary Healthcare

INTRODUCTION

Sarcopenia, characterized by progressive skeletal muscle loss, has emerged as a significant public health concern, with a global prevalence of 10-27%. While traditionally studied in geriatric populations, recent evidence indicates its impact on individuals aged 40 and above, with early manifestations of muscle decline. Primary care settings play a pivotal role in the early identification and management of sarcopenia, facilitating timely diagnosis and intervention. This study aims to evaluate the prevalence of sarcopenia and its associated factors among individuals aged 40 and above attending a family medicine outpatient clinic.

METHODS

A cross-sectional study was conducted in a family medicine outpatient clinic, including participants aged 40 and above. Participants underwent handgrip strength measurements, calf circumference measurements, and a 4-m walking test. Based on the criteria of the European Working Group on Sarcopenia in Older People 2 (EGSWOP2), individuals with sarcopenia and those at risk of sarcopenia were identified. The Mini Nutritional Assessment (MNA) was used to assess nutritional status. Sociodemographic characteristics, comorbidities, and laboratory values were recorded. A comparison was made between individuals with normal muscle strength and those at risk of sarcopenia.

RESULTS

Among 213 individuals, 33 (15.4%) were at risk of sarcopenia (probable sarcopenia), and 12 (5.6%) were diagnosed with sarcopenia. There was a negative correlation observed between age and muscle strength (r=-0,339, p<0,001), and positive correlation was found between muscle strength and MNA score (r=0.301, p<0.001). Individuals with higher education and income levels exhibited higher muscle strength. Participants at risk of sarcopenia had higher prevalence rates of comorbidities such as diabetes mellitus (DM), chronic kidney disease, and cardiovascular disease (p=0.20, p<0.01, p=0.015, respectively).

CONCLUSION

Our study highlights the prevalence and associated factors of sarcopenia in individuals aged 40 and above emphasizing the need for screening and intervention strategies in primary care settings. The study findings support the role of primary care in addressing sarcopenia and improving patient outcomes.

Preventing Dementia-A Cross-Sectional Study of Outpatients in a Tertiary Internal Medicine Department

Dementia is a significant health problem worldwide, being the seventh leading cause of death (2,382,000 deaths worldwide in 2016). Recent data suggest there are several modifiable risk factors that, if addressed, can decrease dementia risk. Several national dementia screening programs exist; however, limited-income countries do not have the means to implement such measures. We performed a prospective cross-sectional study in an outpatient department to identify individuals at risk for dementia. Patients with no known cognitive dysfunction seeking a medical consult were screened for dementia risk by means of the cardiovascular risk factors, ageing, and dementia (CAIDE) and modified CAIDE tests. Additionally, we collected demographic and clinical data and assessed each participant for depression, mental state, and ability to perform daily activities. Of the 169 patients enrolled, 63.3% were identified as being in the intermediate-risk or high-risk group, scoring more than seven points on the mCAIDE test. Over 40% of the elderly individuals in the study were assessed as "somewhat depressed" or "depressed" on the geriatric depression scale. Almost 10% of the study population was diagnosed de novo with cognitive dysfunction. In conclusion, using a simple questionnaire such as the mCAIDE in a predefined high-risk population is easy and does not represent a major financial burden. At-risk individuals can subsequently benefit from personalized interventions that are more likely to be successful. Limited-resource countries can implement such screening tools in outpatient clinics.

Evaluation of the effect of fish oil in the prevention of pressure ulcers in patients admitted to the intensive care unit

Introduction

Today, the anti-inflammatory property of fish oil is used to heal wounds, but this property has not been investigated to prevent the occurrence of pressure ulcers. So the research team decided to evaluate this feature as well.

Materials and methods

This clinical trial study was performed on 102 patients admitted to the intensive care unit located at Besat Hospital in 2020. Samples were assigned to three groups control, placebo, and intervention using permutation blocks. Before the intervention, the questionnaire of demographic and clinical variables, level of consciousness, Braden scale, and short nutritional status questionnaire was completed by the main researcher. In the intervention group, in addition to routine care, 2 cc of fish oil was gently rubbed into the sacrum once a day for 5 days. The same intervention was repeated in the placebo group, with the difference that soybean oil was used instead of fish oil, and the control group received only the usual care. The daily evaluation of pressure ulcers by one of the ICU nurses lasted up to 6 days.

Results

The results showed that there was a significant difference in the incidence of pressure ulcers in the three groups (P = 0.043). The risk of pressure ulcers in the control group was 11.9 and 2.7 times higher than the fish oil group and placebo group (P = 0.023) & (P = 0.132).

Conclusion

The use of topical fish oil can be effective in preventing pressure ulcers.

Prevalence of Malnutrition in Patients with Parkinson's Disease: A Systematic Review

OBJECTIVES

This systematic review analyzed the prevalence of malnutrition in patients with Parkinson's Disease.

STUDY DESIGN

a systematic review.

METHOD

Four databases-Cochrane, PubMed, Embase and Web of Science-were searched from October 2021 to June 2022 by two independent researchers. The inclusion criteria were as follows: patients above 18 years old with confirmed Parkinson's Disease, performed screening nutritional assessment, cohort studies, case-control studies, and cross-sectional studies. Patients without Parkinson's Disease and with other parkinsonian syndromes were excluded.

RESULTS

49 studies were included in this systematic review. Patients ranged in age from 20 to 96 years. There were 5613 subjects included. According to Mini Nutritional Assessment, 23.9% (n = 634) participants were at risk of malnutrition and 11.1% (n = 294) were malnourished. According to BMI score, most patients were either obese or overweight.

CONCLUSIONS

the prevalence of malnutrition or risk of malnutrition in the study group was significant. Therefore, more specific and detailed studies on the prevalence of malnutrition in patients with Parkinson's Disease are needed.

Rheumatoid arthritis and nutritional profile: A study in Brazilian females

BACKGROUND

Patients with rheumatoid arthritis (RA) may have nutritional impairment. In RA, muscle loss is associated with an increase in fat tissue, and the patients may not have body mass index (BMI) alterations.

AIM

To study the nutritional status in a sample of patients with RA in Brazil through mini nutritional assessment (MNA) and electric bioimpedance and its relationship to BMI, functionality, disease activity, and treatment.

METHODS

Seventy-one RA females were included. Chart review was used to obtain epidemiological, clinical, and treatment data. Patients answered the MNA and were submitted to electrical bioimpedance and anthropometric measurements. Disease activity was assessed through simple disease activity index (SDAI), clinical disease activity index (CDAI), and function, through health assessment questionnaire (HAQ).

RESULTS

According to MNA, 23 (32.4%) patients were at risk for malnutrition and 1 (1.4%) was malnourished. MNA were associated with disease activity and function impairment (SDAI P = .02; CDAI P = .02, and HAQ P = .002) but not with used medications. According to BMI, 76% were overweight or obese. An increased percentage of body fat was found in 98.7% and a lower percentage of lean mass in 95.7%. Disease activity and function were not associated with the percentage of body fat of any used medications, with a lower percentage of body fat in those using abatacept (P = .01).

CONCLUSION

Almost one-third of patients had nutritional impairment according to MNA which was associated with disease activity and loss of function. Almost the whole sample had an increased percentage of fat mass and a diminished percentage of muscle mass that could not be linked with disease activity, function or used medications.

Validity and Predictive Performance of Mini Nutritional Assessment Tool for Institutionalized Elders in Ethiopia

Background

Despite the high burden of malnutrition in the country, there is a lack of a simple and valid tool to screen elders in Ethiopia. The Mini Nutritional Assessment (MNA) tool has been validated for comprehensive geriatric assessment to identify malnutrition in other countries. However, there is a lack of evidence on the potential validity and reliability of the tool for institutionalized elders in Ethiopia. This study was aimed at determining the validity and predictive performance of MNA tool for malnutrition among Ethiopian institutionalized elderly.

Methods

A facility-based survey was conducted on randomly selected 164 elders in geriatric centers to evaluate the validity, reliability, and predictive performance of full MNA against hemoglobin (Hgb) and ideal body weight (IBW) measured under standard procedures. The data was presented in ROC graphs, and reliability was evaluated with Cronbach alpha. The receiver-operating characteristic curve (ROC) analysis was used to assess the predictive performance of the tool. The area under the curve (AUC) with its 95% CI was reported. The Youden index, at maximum sensitivity and specificity, was used to obtain optimal cutoff points.

Results

The internal consistency of the tool was good (α = 0.80). The full MNA score can better predict Hgb (AUC = 0.845; 0.783-0.899) and percentage of IBW (AUC = 0.90; 0.842-0.941) at specified cutoff points. A full MNA can predict malnutrition or risk of malnutrition based on percentage IBW at a sensitivity and specificity of 97.3% and 72.2%, respectively.

Conclusions

The full MNA has the potential to be a reliable and valid nutritional assessment tool for institutional elders.

Topical Almond Oil for Prevention of Pressure Injuries: A Single-Blinded Comparison Study

PURPOSE

The aim of our study was to determine the effect of topical almond oil for prevention of pressure injuries.

DESIGN

Single-blind randomized clinical trial.

SAMPLE AND SETTING

Patients admitted to an intensive care unit in Besat Hospital, Hamadan, Iran, were invited to participate in the trial. Data were collected over an 8-month period.

METHODS

A convenience sample of 108 patients, using a permuted block randomization method was assigned to 3 equal groups that received the intervention almond oil, placebo (liquid paraffin), or control (standard of care). Data included demographic information, Braden Scale score, and National Pressure Ulcer Advisory Panel-European Pressure Ulcer Advisory Panel (NPUAP-EPUAP) pressure injury staging system classification score. The intervention and placebo groups received daily application of 6.5 cc of topical almond oil or paraffin to the sacrum, heels, and shoulders for 7 consecutive days. The skin was evaluated for pressure injuries by an expert nurse who was blinded to groups. Chi-square test, analysis of variance, and regression analyses were used to evaluate relationships within and between groups for study variables, incidence of pressure injuries, and duration of time of onset of pressure injuries. P values less than .05 were deemed statistically significant.

RESULTS

The incidence of pressure injury in the almond oil group (n = 2; 5.6%) was lower than that in the placebo (n = 5; 13.9%, P = .189) or control groups (n = 9; 25.1%, P = .024). The incidence of pressure injuries in the control group was 6.8 and 2.12 (P = .227) times higher than that in the almond and placebo groups, respectively. The onset day of a pressure injury occurred 5.4 days after initiation of the protocol in the almond oil group compared to 4.22 days in the control group (P = .023) and 5 days in the placebo group (P = .196).

CONCLUSION

The topical application of almond oil was associated with a lower incidence of pressure injuries and that developed later during the study compared to participants who received paraffin or standard of care only. Further study is recommended to advance this work in populations at risk for pressure injury.

Prevalence of malnutrition/malnutrition risk and nutrition-related risk factors among patients with Parkinson's disease: systematic review and meta-analysis

INTRODUCTION

The clinical symptoms and nutritional status of patients with Parkinson's disease (PwP) are interrelated, and the clinical outcomes in malnourished patients are often poor. Only a few studies have reviewed the prevalence of malnutrition and nutrition-related risk factors in PwP.

OBJECTIVE

To explore the prevalence of malnutrition/ malnutrition risk among PwP, and estimate nutrition-related risk factors.

METHODS

PubMed, EMBASE, and Cochrane Library were systematically searched. Literatures published between 1 January 1995 and 1 November 2020, subjects were patients with idiopathic PD underwent Mini Nutritional Assessment (MNA) were included.

RESULT

Sixteen articles, including 1650 PwP from 13 countries/regions, were included in the meta-analysis. The prevalence of malnutrition and malnutrition risk were 8.8% (Confidence interval [CI] 95%, 5.3%-12.2%) and 35.3% (CI 95%, 29.0%-41.7%), and the prevalence of nutritional disorders was 42.3% (CI 95%, 33.7%-51%). The prevalence of malnutrition in developing countries was higher than that in the developed countries. Meta-analysis reveals there were significant differences in the course of the disease (0.88 years; 95% CI, 0.26-1.50), levodopa equivalent daily dose (LEDD; 60.77 mg/day; 95% CI, 2.7-118.8), Hoehn and Yahr (H&Y) staging (0.323; CI 95%, 0.164-0.482), and unified Parkinson's disease rating scale (UPDRS) scores (total: 13.66, CI 95%: 10.57-16.75 and part III: 5.52, CI 95%: 3.79-7.25) between normal and nutritional disorder groups.

CONCLUSIONS

Malnutrition/malnutrition risk prevalence in PwP are high. The duration of the disease, LEDD, H&Y staging, and UPDRS score (part III and total) may be nutrition-related risk factors in PwP.

MNA-SF is not sufficient without questioning protein and fruit-vegetable consumption to detect malnutrition risk in Parkinson's Disease

Malnutrition risk (MR) prevalence in Parkinson's Disease (PD) is 3-60%. Mini-Nutritional Assessment (MNA) and MNA-SF are the widely Query used measurements for MR. The aim of this study was to identify if MNA-SF is sufficient to detect MR instead of total MNA in PD. Participants were compared in terms of anthropometric measurements, MNA (total, screening and evaluation), non-motor questionnaire, beck depression inventory, beck anxiety inventory. They were additionally compared according to evaluation part of MNA. All PD patients were divided into two groups as "with MR" and "without MR" according to total MNA scores and comparisons were done again. Then, IPD patients whose MNA-SF scores were normal were divided into another two subgroups as "with MR" and "without MR" according to total MNA scores and compared again. 58.7% PD patients and 28.6% controls were at MR. 32.5% PD patients whose MNA-SF scores were normal were detected as "with MR" by total MNA. MNA-SF had 87.1% sensitivity, 70.5% specificity, 67.5% positive predictive value, 88.6% negative predictive value and 77.3% accuracy in PD. PC and FVC were found to be the most important questions in MR estimation. Total MNA was sufficient to measure MR in PD, however MNA-SF missed many patients who were at MR. PC and FVC should be insistently questioned in addition to MNA-SF to find the accurate results of MR in PD patients, especially in females with higher disease severity and duration.

Clinical measurement properties of malnutrition assessment tools for use with patients in hospitals: a systematic review

Background

The use of malnutrition outcome measures (OM) by registered dietitians (RD) with inpatients in hospitals has increased promoting the achievement of nutritional care goals and supporting decision-making for the allocation of nutritional care resources in hospitals. There are 3 commonly used OMs: Subjective Global Assessment (SGA), Patient Generated-Subjective Global Assessment (PG-SGA) and Mini Nutritional Assessment (MNA). The purpose of this current study was to systematically review the evidence of the clinical measurement properties of malnutrition assessment tools for use with patients admitted in hospitals.

Methods

MEDLINE, Cinahl, EMBASE, and PubMed were searched for articles published between 2000 and 2019. Research articles were selected if they established reliability, validity, and responsiveness to change properties of the SGA, PG-SGA and MNA tools, were written in English, and used any of these OMs as an outcome measure. Abstracts were not considered. The risk of bias within studies was assessed using the Quality Appraisal for Clinical Measurement Study (QA-CMS).

Results

Five hundred five studies were identified, of which 34 articles were included in the final review: SGA (n = 8), PG-SGA (n = 13), and MNA (n = 13). Of the 34 studies, 8 had a quality score greater than 75%; 23 had a quality score of 40–75% and 3 studies had a quality score of less than 40%. PG-SGA was found to have excellentdiagnostic accuracy (ROC: 0.92–0.975; Sensitivity: 88.6–98%; Specificity: 82–100%), sufficient internal consistency (Cronbach’s alpha: 0.722–0.73), and strong test-retest reliability (r = 0.866). There was insufficient evidence to suggest adequate diagnostic accuracy and good inter-rater reliability for SGA. Only one study examined the minimum detectable change of MNA (MDC = 2.1).

Conclusions

The evidence of validity for the existing malnutrition assessment tools supports the use of these tools, but more studies with sound methodological quality are needed to assess the responsiveness of these OMs to detect the change in nutritional status.

The Physical Activity and Fall Risk Among Iranian Older Male Adults

Background:

Fall is a major cause of disability and mortality in the elderly.

Objective:

The aim of the present study was to investigate the relationship between the level of physical activity and falls in elderly men in Tehran.

Methods:

The subjects of this study included 434 elderly males over the age of 60 in Tehran, who were randomly selected from parks in different parts of Tehran. The data was collected from August to September, 2019. The demographic characteristics of the subjects were collected and recorded. Then, body composition and anthropometric indices including weight, body mass index (BMI), height and calf circumferences (CC), waist circumferences (WC) and hip circumferences were measured using a digital scale of OMRON and meter tape. The level of physical activity and nutritional status were calculated using the questionnaires of physical activity scale for the elderly (PASE) and mini nutritional assessment (MNA), respectively. The Short Physical Performance Battery (SPPB) test was used to assess the risk of falling. Statistical analysis of data was performed using SPSS21 software.

Results:

The results of statistical analysis of the data showed a positive and significant relationship between global physical activity level (P<0.000) and subscales of its domains (P<0.000) with fall score and a significant inverse relationship between age and fall score (P<0.000). In addition, it was found that age (P<0.000) and physical activity (P<0.000) are two strong factors in predicting falls in the elderly.

Conclusion:

Based on the resulting positive relationship between physical activity and falls, it can be stated that the using strategies such as increasing sports environments with a focus on exercise, physiologists can play an effective role in preventing falls and related complications in the elderly.

Nutritional Status Associated with Molecular Biomarkers, Physiological Indices, and Clinical Severity in Parkinson's Disease Patients

This study is intended to explore the associations between nutritional status and molecular biomarkers and the clinical severity of Parkinson's disease (PD), as well as to examine the differences in related factors between PD patients with normal nutrition and those with at risk for malnutrition. A cross-sectional assessment of 82 consecutive outpatients with PD was conducted using the mini nutritional assessment (MNA), Unified Parkinson's Disease Rating Scale (UPDRS), and the Hoehn and Yahr scale to determine the nutritional status, the clinical severity of PD, and the stage of the disease. Recordings of blood samples collected after 12 h of overnight fasting were also assessed in terms of serum levels of glycated hemoglobin (HbA1c), blood urea nitrogen (BUN), creatinine, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), hemoglobin (Hgb), folate, and vitamin B12. All participants were divided into normal nutrition and malnutrition risk groups via the MNA scores to compare the above-mentioned parameters. The results showed that the total MNA score was significantly correlated with some parts of the UPDRS scale (e.g., Sections 1 and 2) and the levels of HbAlc in PD patients and those with risk for malnutrition, with significantly lower weight and body mass index (BMI), and with lower levels of Hgb and HDL. Higher levels of cholesterol were observed in the malnutrition risk group as compared with the normal nutrition group. The findings suggest that the clinical severity of PD is associated with nutritional status. Body weight, BMI, and the levels of Hgb, cholesterol, and HDL could be, at least partially, important biological markers to monitor malnutrition and the progression of the disease.

Comparison of Three Nutritional Screening Tools with the New Glim Criteria for Malnutrition and Association with Sarcopenia in Hospitalized Older Patients

The integrated assessment of nutritional status and presence of sarcopenia would help improve clinical outcomes of in-hospital aged patients. We compared three common nutritional screening tools with the new Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria among hospitalized older patients. To this, 152 older patients were assessed consecutively at hospital admission by the Malnutrition Universal Screening Tool (MUST), the Subjective Global Assessment (SGA), and the Nutritional Risk Screening 2002 (NRS-2002). A 46% prevalence of malnutrition was reported according to GLIM. Sensitivity was 64%, 96% and 47%, and specificity was 82%, 15% and 76% with the MUST, SGA, and NRS-2002, respectively. The concordance with GLIM criteria was 89%, 53% and 62% for the MUST, SGA, and NRS-2002, respectively. All the screening tools had a moderate value to diagnose malnutrition. Moreover, patients at high nutritional risk by MUST were more likely to present with sarcopenia than those at low risk (OR 2.5, CI 1.3-3.6). To conclude, MUST is better than SGA and NRS-2002 at detecting malnutrition in hospitalized older patients diagnosed by the new GLIM criteria. Furthermore, hospitalized older patients at high risk of malnutrition according to MUST are at high risk of presenting with sarcopenia. Nutritional status should be determined by MUST in older patients at hospital admission, followed by both GLIM and the European Working Group on Sarcopenia in Older People (EWGSOP2) assessment.

Malnutrition Screening and Assessment in Hospitalised Older People: a Review

Malnutrition (undernutrition) remains one of the most serious health problems for older people worldwide. Many factors contribute to malnutrition in older people, including: loss of appetite, polypharmacy, dementia, frailty, poor dentition, swallowing difficulties, social isolation, and poverty. Malnutrition is common in the hospital setting, yet often remains undetected by medical staff. The objective of this review is to compare the validity and reliability of Nutritional Screening Tools (NSTs) for older adults in the hospital setting. We also provide an overview of the various nutritional screening and assessment tools used to identify malnutrition in hospitalised older adults. These include: Subjective Global Assessment (SGA), the Mini Nutritional Assessment (MNA), MNA-short form (MNA-SF), Malnutrition Universal Screening Tool (MUST), Simplified Nutritional Appetite Questionnaire (SNAQ), Geriatric Nutrition Risk Index (GNRI) and anthropometric measurements. The prevalence and outcomes of malnutrition in hospitalised older adults are also addressed.

Geriatric nutritional risk index as a simple tool for assessment of malnutrition among geriatrics in Northwest of Iran: comparison with mini nutritional assessment

BACKGROUND

Older people are more likely to develop nutritional problems and timely diagnosis of malnutrition is crucial to prevent hazardous consequences following poor nutrition.

AIMS

To evaluate the efficacy of Geriatric Nutritional Risk Index (GNRI) to assess nutritional status among non-hospitalized elderly, compared to mini nutritional assessment (MNA) among Iranian seniors.

METHODS

One hundred and sixty-four subjects, aged ≥ 65 years old were recruited to our cross-sectional study from various districts of Tabriz (Tabriz, Iran). Anthropometric and biochemical measurements were performed, short- and long-form MNAs and GNRI were assessed in our study subjects. Sensitivity, specificity and predictive values of the three indices, agreement between them, and their correlation with anthropometric and biochemical parameters were evaluated. Receiver-operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off point for GNRI in our study population.

RESULTS

GNRI had lower sensitivity (50, 57%), but optimal specificity (94, 93%) and lower negative predictive value (NPV; 68, 71%) compared to MNA-LF and MNA-SF, respectively. We found a moderate agreement between GNRI and MNA-SF (K = 0.52) and MNA-LF (K = 0.46) scores. Significant correlations were observed between re-categorized MNAs as well as GNRI scores, and age, weight, MAC, CC, WC, albumin, and pre-albumin. The cut-off point of 110.33 was obtained for GNRI, according to the ROC curve.

CONCLUSIONS

Although GNRI may not be an efficient tool for screening malnutrition due to its lower sensitivity, it is moderately correlated with MNAs and also more useful when limited funding needs to target the truly malnourished seniors.

Weight Loss and Malnutrition in Patients with Parkinson's Disease: Current Knowledge and Future Prospects

Parkinson's Disease (PD) is currently considered a systemic neurodegenerative disease manifested with not only motor but also non-motor symptoms. In particular, weight loss and malnutrition, a set of frequently neglected non-motor symptoms, are indeed negatively associated with the life quality of PD patients. Moreover, comorbidity of weight loss and malnutrition may impact disease progression, giving rise to dyskinesia, cognitive decline and orthostatic hypotension, and even resulting in disability and mortality. Nevertheless, the underlying mechanism of weight loss and malnutrition in PD remains obscure and possibly involving multitudinous, exogenous or endogenous, factors. What is more, there still does not exist any weight loss and malnutrition appraision standards and management strategies. Given this, here in this review, we elaborate the weight loss and malnutrition study status in PD and summarize potential determinants and mechanisms as well. In conclusion, we present current knowledge and future prospects of weight loss and malnutrition in the context of PD, aiming to appeal clinicians and researchers to pay a closer attention to this phenomena and enable better management and therapeutic strategies in future clinical practice.

Comprehensive comparison of malnutrition and its associated factors between nursing home and community dwelling elderly: A case-control study from Northwestern Iran

BACKGROUND & AIMS

Only a limited number of studies have compared nursing home and community residing elderly in terms of health-related issues. The present study aimed to compare nutritional status and its associated factors between nursing home residents and community-dwelling seniors.

METHODS

In this case-control, age- and gender-matched study in Tabriz (East Azarbaijan, Iran), elderly subjects aged 65 years and older were recruited from nursing homes (n = 76) and community (n = 88). Anthropometric, blood pressure and dietary intake measurements, as well as biochemical assays were performed. Nutritional status (Mini Nutritional Assessment: MNA), cognitive function (Mini Mental State Examination: MMSE) and physical performance (Barthel Index) were assessed and compared between the two settings.

RESULTS

Nursing home residents had significantly lower body mass index (BMI), limbs, waist and hip circumferences, and diastolic blood pressure. Caloric and protein intake of the groups were similar, while nursing home residents received lower amounts of many micronutrients and saturated fats and higher polyunsaturated fats. MNA, MMSE and Barthel index scores were significantly different between the groups, all of them in favor of the free living elderly (p < 0.001, p < 0.001 and p = 0.014, respectively). Laboratory tests revealed significantly lower levels of hemoglobin, folate, fasting blood sugar, insulin, albumin, prealbumin, creatinine and uric acid in the nursing home group; however, mean cell volume (MCV) and HDL-cholesterol were higher in this group.

CONCLUSION

Elderly people living in nursing homes have lower BMI, suffer from many nutritional deficiencies and are predisposed to malnutrition, impaired cognition and deteriorating physical performance, compared to community dwelling seniors.

Sexual dimorphism in Parkinson's disease: differences in clinical manifestations, quality of life and psychosocial functioning between males and females

INTRODUCTION

Sex-related differences in clinical manifestations and consequences of Parkinson's disease (PD) have been poorly explored. Better understanding of sexual dimorphism in neurologic diseases such as PD has been announced as a research priority. The aim of our study was to determine independent sex differences in clinical manifestations and subtypes, psychosocial functioning, quality of life (QoL) and its domains between male and female individuals with PD.

PATIENTS AND METHODS

A comprehensive list of demographics, motor symptoms and subtypes, nonmotor features, health-related quality of life (HRQoL), psychosocial functioning and general aspects of daily life was assessed in 157 individuals (108 males and 49 females) with idiopathic PD. In order to control for potential confounding variables, we applied Orthogonal Partial Least Squares - Discriminant Analysis (OPLS-DA) to explore the strength of each feature to discriminate male and female patients with PD.

RESULTS

While no sex difference was found in the total Unified Parkinson's Disease Rating Scale (UPDRS) score and cumulative daily dose of levodopa, females had significantly more severe anxiety (mean difference =2.2 [95% confidence interval, CI: 0.5-4.0], P=0.011), worse nutritional status (23.8 [standard deviation, SD =4.2] vs 25.8 [SD =2.6], P=0.003) and poorer QoL (28.3 [SD =15.7] vs 17.9 [SD =14.2], P<0.001). Based on multivariate discriminant analysis, emotional well-being, bodily discomfort, social support, mobility and communication domains of HRQoL, together with anxiety, depression and psychosocial functioning, were the strongest features with more severe/worse status in females after adjustment for potential statistical confounders.

CONCLUSION

Our study provides a comprehensive understanding of sexual dimorphism in PD. Anxiety, depression, specific domains of HRQoL (mobility, emotional well-being, social support and bodily discomfort) and psychosocial functioning were significantly worse in female individuals with PD. Sexual dimorphism in PD highlights the features that are more likely to be affected in each sex and should be specifically targeted when managing male and female individuals with PD.

Clinical value of nutritional status in neurodegenerative diseases: What is its impact and how it affects disease progression and management?

Neurodegenerative diseases constitute a major problem of public health that is associated with an increased risk of mortality and poor quality of life. Malnutrition is considered as a major problem that worsens the prognosis of patients suffering from neurodegenerative diseases. In this aspect, the present review is aimed to critically collect and summarize all the available existing clinical data regarding the clinical impact of nutritional assessment in neurodegenerative diseases, highlighting on the crucial role of nutritional status in disease progression and management. According to the currently available clinical data, the nutritional status of patients seems to play a very important role in the development and progression of neurodegenerative diseases. A correct nutritional evaluation of neurodegenerative disease patients and a right nutrition intervention is essential in monitoring their disease.

Heterogeneous Determinants of Quality of Life in Different Phenotypes of Parkinson's Disease

OBJECTIVES

Health-related quality of life (HRQoL) is considered a very important outcome indicator in patients with Parkinson's disease (PD). A broad list of motor and non-motor features have been shown to affect HRQoL in PD, however, there is a dearth of information about the complexity of interrelationships between determinants of HRQoL in different PD phenotypes. We aimed to find independent determinates and the best structural model for HRQoL, also to investigate the heterogeneity in HRQoL between PD patients with different phenotypes regarding onset-age, progression rate and dominant symptom.

METHODS

A broad spectrum of demographic, motor and non-motor characteristics were collected in 157 idiopathic PD patients, namely comorbidity profile, nutritional status, UPDRS (total items), psychiatric symptoms (depression, anxiety), fatigue and psychosocial functioning through physical examination, validated questionnaires and scales. Structural equation model (SEM) and multivariate regressions were applied to find determinants of Parkinson's disease summary index (PDSI) and different domains of HRQoL (PDQ-39).

RESULTS

Female sex, anxiety, depression and UPDRS-part II scores were the significant independent determinants of PDSI. A structural model consisting of global motor, global non-motor and co-morbidity indicator as three main components was able to predict 89% of the variance in HRQoL. In older-onset and slow-progression phenotypes, the motor domain showed smaller contribution on HRQoL and the majority of its effects were mediated through non-motor features. Comorbidity component was a significant determinant of HRQoL only among older-onset and non-tremor-dominant PD patients. Fatigue was not a significant indicator of non-motor component to affect HRQoL in rapid-progression PD.

CONCLUSIONS

Our findings showed outstanding heterogeneities in the pattern and determinants of HRQoL among PD phenotypes. These factors should be considered during the assessments and developing personalized interventions to improve HRQOL in PD patients with different phenotypes or prominent feature.
