The nutritional status of Dutch elderly patients with Parkinson’s disease

Objectives: To assess the prevalence of (risk of) undernutrition in Dutch elder Parkinson’s disease patients as well as it’s risk factors. Design: Observational cross-sectional study. Setting: An outpatient clinic at the department Neurology of Medical Centre Leeuwarden, a large teaching hospital. Participants: 102 outpatients with Parkinson’s disease aged 65 years and older were recruited. Measurements: Data regarding various aspects of undernutrition including socio-demographic aspect, disease characterisitics, nutritional status, appetite and overall-physical and psychological functioning were collected. Results: Undernutrition was diagnosed in 2.0% and 20.5% of the patients were categorized as being at risk of undernutrition. Care dependency and appetite were the two risk factors with the highest predictive value for an unfavorable nutritional status. Conclusion: Of Dutch elderly patients with Parkinson’s Disease 22.5% had an unfavourable nutritional status. Dependency and appetite were the two risk factors with the highest predictive value fort his outcome. Because undernutrition can be regarded as a geriatric syndrome a comprehensive nutritional assessment should be done followed by nutritional interventions next to interventions focused on the risk factors. Further studies are needed to evaluate these interventions.

Does perioperative immunonutrition reduce postoperative complications in patients with gastrointestinal cancer undergoing operations?

Perioperative immune modulation using specialized enteral diets containing specific immunonutrients may improve postoperative outcomes in critically ill patients compared with standard formulas. A study from Italy involving 305 patents with histologically confirmed cancer of the gastrointestinal tract undergoing major elective surgery and preoperative weight loss < 10% demonstrated that a specialized preoperative oral formula enriched with arginine, omega-3 fatty acids, and RNA for 5 days before surgery with no nutritional support postoperatively (preoperative group) was as effective as pre- and postoperative administration of the same enriched formula (perioperative group) in decreasing the incidence of postoperative infections and length of hospital stay. Both pre- and perioperative immunonutritional strategies were superior to the conventional approach (no artificial nutrition perioperatively).     

Aortic features in tangier disease and pathogenetic considerations — Part I. Fatty dots and streaks

Morphological studies of aortic fatty dots and streaks, and the adjacent normally appearing intima, in a 5 3/4-year-old boy who died of pneumonia, showed several hitherto unreported features. In lesions, lipid vacuoles and/or other cytoplasmic “inclusions” (ultrastructurally considered to present complex forms of lipids) were present on occasion in the endothelium but consistently involved the (intimal) smooth muscle cells (SMC). Similar changes were present in the adjacentintima, but were here less prominent and “tapered off” distally. A moderate number of macrophages also contained cytoplasmic lipids but such cells entirely free of lipid inclusions were observed, too.Most surprisingly, dilated and manycisternae of rough-surfaced endoplasmicreticulum (ER) in the SMC of lesions were associated spatially with cytoplasmic droplets and other forms of lipids.The results of these studies question the generally accepted central role of macrophages as being primarily involved in the pathogenesis of tissue changes in Tangier disease. It is possible that in view of the absence or paucity of high-density lipoproteins (HDL) and alterations of (their) apo A-I and apo A-II (as well as of other lipids), the arterial SMC may be in some way involved in the metabolism of the above substances in this disorder.Support of this tentative (and highly speculative) assumption must await further work utilizing tissues and cells other than those containing macrophages and other derivatives of reticuloendothelial system.     

Nutritional status and dietary habits in Parkinson’s disease patients in Ghana

ObjectiveDietary treatment is important for the management of Parkinson’s disease (PD). Our objective was to describe the dietary habits and assess the nutritional status of Ghanaian patients with PD. This study is part of a larger project, for which Ghana has been selected as a pilot country.MethodsFifty-five Ghanaian patients with PD and 12 healthy Ghanaian controls were recruited. We assessed nutritional status, investigated dietary habits, and assessed the prevalence of the nutritional complications of PD (e.g., constipation and dysphagia).ResultsThe mean daily caloric intake was about 1200 kcal/d in patients with PD and in controls. The typical diet was based on semisolid foods, usually vegetable soups accompanied by cereal flour or root starch or sometimes chicken or fish. The intake of milk and its derivatives was low. The prevalences of constipation and dysphagia in patients with PD were 49% and 21%, respectively.ConclusionThis study has yielded information that could be useful for the study of the management of PD and for the assessment of response to therapy.     

Cardiometabolic factors and disease duration in patients with Parkinson’s disease

ObjectivePrevious studies have reported that patients with Parkinson’s disease (PD) have a favorable cardiometabolic risk profile. The aim of this study was to investigate the relationship between cardiometabolic risk factors and the duration of disease.MethodsOne hundred and fifty patients with PD (56.7% men) were studied, measuring body mass index (BMI), waist circumference (WC), body fat percentage (BF%) by impedance, fasting glucose, serum lipids, and transaminases.ResultsIn sex- and age-adjusted correlation models, duration of PD was inversely related to BMI (r = ?0.20; P < 0.05) and BF% (r = ?0.29; P < 0.005). Using multivariable regression models (adjustments: age, gender, smoking status, levodopa dose and, alternatively, BMI, WC, or BF%), high-density lipoprotein (HDL) levels were positively correlated with disease duration (P < 0.01 for all). In models adjusted for WC and BF%, total HDL-cholesterol ratio was also inversely associated with duration of PD (P < 0.05 for both). No other association between biochemical variables and the duration of PD was found. Moreover, no dose–response effect of levodopa on metabolic risk factors was observed.ConclusionsHDL levels and total HDL-cholesterol ratio were favorably associated with duration of PD. This factor may contribute to cardiometabolic protection in PD. The mechanisms underlying this association deserve further investigation.     

Nutritional status in Parkinson’s disease patients undergoing deep brain stimulation surgery: A pilot study

Objectives

People with Parkinson’s disease (PD) are at higher risk of malnutrition due to PD symptoms and pharmacotherapy side effects. When pharmacotherapy is no longer effective for symptom control, deep-brain stimulation (DBS) surgery may be considered. The aim of this study was to assess the nutritional status of people with PD who may be at higher risk of malnutrition related to unsatisfactory symptom management with optimised medical therapy.

Design

This was an observational study using a convenience sample.

Setting

Participants were seen during their hospital admission for their deep brain stimulation surgery.

Participants

People with PD scheduled for DBS surgery were recruited from a Brisbane neurological clinic (n=15).

Measurements

The Patient-Generated Subjective Global Assessment (PG-SGA), weight, height and body composition were assessed to determine nutritional status.

Results

Six participants (40%) were classified as moderately malnourished (SGA-B). Eight participants (53%) reported previous unintentional weight loss (average loss of 13%). On average, participants classified as well-nourished (SGA-A) were younger, had shorter disease durations, lower PG-SGA scores, higher body mass (BMI) and fat free mass indices (FFMI) when compared to malnourished participants (SGA-B). Five participants had previously received dietetic advice but only one in relation to unintentional weight loss.

Conclusion

Malnutrition remains unrecognised and untreated in this group despite unintentional weight loss and presence of nutrition impact symptoms. Improving nutritional status prior to surgery may improve surgical outcomes.     

Type D, anxiety and depression in association with quality of life in patients with Parkinson’s disease and patients with multiple sclerosis

Purpose

The present study examines the role of Type D personality, anxiety and depression in quality of life (QoL) in patients with two chronic neurological diseases—Parkinson’s disease (PD) and multiple sclerosis (MS).

Methods

This cross-sectional study included 142 PD patients (73 % males; mean age 67.6 ± 9.2 years) and 198 patients with MS (32.3 % males; 38.4 ± 10.8 years). Multiple regression analyses were used to analyze the association of UDPRS (PD patients) or EDSS (MS patients), Type D personality (DS-14) and anxiety and depression (HADS) with the physical (PCS) and mental summary (MCS) of QoL, as measured by the SF-36.

Results

In PD patients, Type D was significantly associated with MCS only; in MS patients, Type D was significantly associated with both dimensions—MCS and PCS. After adding anxiety and depression, the importance of Type D for the QoL model dramatically decreased. Anxiety and depression were strongly associated with lower scores in MCS and PCS in both PD and MS patients.

Conclusions

The actual mood of PD and MS patients—the level of anxiety or depression—might have a greater impact on patients’ QoL than their personality. Further longitudinal research should focus on how the pathway consisting of personality traits, anxiety and depression, and QoL might be constructed.     

Neuroticism and extraversion in association with quality of life in patients with Parkinson’s disease

Purpose  Personality traits appear as determinants of quality of life (QoL) in most chronic diseases. The aim of this study is to explore whether neuroticism and extraversion contribute to the variance in QoL in patients with Parkinson’s disease (PD) when controlled for age, functional status and disease duration. Methods  The Parkinson’s Disease Quality of Life Questionnaire (PDQ-39) was used to assess QoL and the Unified Parkinson’s Disease Rating Scale (UPDRS) for disease severity. Neuroticism and extraversion were measured with the Eysenck Personality Questionnaire (EPQR-A). Multiple linear regression analysis was then used to assess the contribution of neuroticism and extraversion to QoL. Results  The sample consisted of 153 PD patients (48.4% women; 67.9 ± 9.3 years; mean disease duration 7.5 ± 5.8 years). Neuroticism was, after disease severity, the second most important variable associated with QoL in PD patients, in particular for domains associated with psychological processes: emotional well-being, social support, stigma and communication. A higher score in extraversion was significantly associated with better emotional well-being in males, but surprisingly, with worse emotional well-being in females. Conclusions  After functional status, personality traits were clearly associated with QoL in PD patients. Therefore, they should be taken into account by health-care professionals in their appraisal of patient complaints.     

Ghrelin and leptin secretion in patients with moderate Alzheimer’s disease

Background

Weight loss is a characteristic finding of patients with Alzheimer??s disease (AD). It seems that precedes cognitive impairment by some years, but the underlying causes are not fully understood. Ghrelin and leptin are involved in energy homeostasis, and may be implicated in weight losing observed in these patients.

Objective

To examine the potential relationship between ghrelin and leptin levels and weight loss in patients with AD.

Design

The study included 27 patients (10 men and 17 women) with AD of moderate severity, and 23 controls (10 males and 13 females), matched for age and BMI. Body fat and lean mass content were assessed using a portable apparatus. Cognitive function was assessed with the Mini-Mental State Examination. Basal serum samples for the measurement of leptin, ghrelin, insulin and glucose were obtained, and serum ghrelin, insulin and glucose were measured after a 75-gr glucose load in both groups.

Results

Patients with Alzheimer Disease (AD) have lower lean mass content compared to controls. Basal ghrelin and leptin is similar in patients with AD and controls. The area-under-the-curve for ghrelin (AUC) is lower in male patients with AD compared to control males, while no difference was observed between females AD and controls.

Conclusion

Male patients with AD, in contrast with female patients, fail to maintain a normal energy homeostasis even in the early stages of the disease, as shown by the decreased lean mass content in males AD compared to controls. Disruption of the normal compensatory modulation of ghrelin secretion might contribute to the metabolic changes observed in male patients with AD.     

Prevalence of pressure ulcers in hospitals in Brazil and association with nutritional status—A multicenter,cross-sectional study

BackgroundPressure ulcers (PU) represent a widespread, painful, and expensive health care problem directly associated with increased morbidity, mortality, and length of hospital stay. The aim of this study was to determine the prevalence of PU in hospitalised patients in public and private Brazilian institutions and the ulcers’ associations with nutritional status and other risk factors.MethodsA multicenter, cross-sectional, quantitative and qualitative study was carried out in hospitals in different geographic regions of Brazil from March 2009 to February 2011. The prevalence and characteristics of PU, the nutritional status and the association between the presence of PU, and the nutritional status and other study variables were evaluated. The association of the presence of PU with the study variables was performed by univariate analyses and multivariate logistic regression models. The final multivariate model was one in which all variables were significant at the 0.05 level.ResultsAccording to the subjective global assessment (SGA), the prevalence of PU was 16.9%, and 52.4% of patients were malnourished. PU and their severity were directly associated with malnutrition (P < 0.05). Patients who are bedridden, who are elderly, who have neurological disorders or cancer, who are staying at a public or private institution, and who are staying at the hospital between 8 d and 15 d had an increased risk of PU (P < 0.05).ConclusionThe prevalence of PU in Brazilian general hospitals is high, and the prevalence of malnutrition is extremely high. Malnourishment is one of the most important risk factors associated with the development and severity of PU in hospitals. Patients who are malnourished are more prone to developing PU.     

Association of obesity,diabetes, and physical frailty with dental and tongue–lip motor dysfunctions in patients with metabolic disease

ObjectiveThis study aimed to reveal the clinical features associated with decreased dental (or shearing/crushing) and tongue–lip motor functions in patients with metabolic diseases.MethodsOne thousand patients with metabolic diseases including diabetes, dyslipidemia, hypertension, and hyperuricemia were recruited. Dental function was assessed with a gummy jelly test, wherein glucose elution from a chewed gummy jelly was measured. Tongue–lip motor function was measured as repeatedly pronounced syllables per second. The association of clinical variables with the two functions was analyzed using multivariate linear regression models.ResultsThe mean measurement of dental function was 202 ± 73 mg/dL, and that of tongue–lip motor function was 5.5 ± 1.0 times/s. Clinical variables independently associated with dental function (mg/dL) were age (adjusted regression coefficient β = ?9.8 per standard deviation [SD]), smoking (β = ?14.4 and ?25.9 for past and current smoking, respectively), body mass index (BMI) 25–30 and ≥30 versus 20–25 kg/m² (β = ?14.7 and ?23.1, respectively), diabetes (β = ?11.9), hemoglobin A1c level ≥64 mmol/mol (β = ?14.6), gait speed (β = 6.2 per SD), and handgrip strength (β = 7.5 and 7.7 per SD for males and females, respectively) (all P < 0.05). Clinical variables independently associated with tongue–lip motor function (times/s) were age (β = ?0.31 per SD), BMI ≥ 30 versus 20–25 kg/m² (β = ?0.24), diabetes (β = ?0.22), dyslipidemia (β = 0.16), gait speed (β = 0.12 per SD), and handgrip strength (β = 0.18 and 0.13 per SD for males and females, respectively) (all P < 0.05).ConclusionsObesity, diabetes, physical frailty, and old age were shared risk factors for decreased dental and tongue–lip motor functions in patients with metabolic diseases.     

Is it possible using handgrip strength instead of body mass index in MNA-SF test to assess the nutritional status of geriatric patients?

Introduction

In Mini-Nutritional Assessment-Short Form (MNA-SF) test, a practical and reliable alternative parameter is still necessary for patients with difficult body mass index evaluation. We aimed to show whether or not handgrip strength may be used instead of body mass index (BMI) in MNA-SF test.

Materials and Methods

MNA-SF test scores, calf circumferences (CC), handgrip strength (HGS), and BMI of 191 patients were evaluated. The first one of calculated MNA-SF tests was with BMI, the second one with CC, and the last one with HGS. Zero point was given if CC was <31 cm and 3 points were given if CC was ≥31 cm. Zero, 1, 2, and 3 points were given if the loss of HGS when compared to expected HGS were ≥%60, from ≥%30 to <%60, from ≥%10 to <%30, and <%10 or greater than expected HGS, respectively. MNA-SF scores and nutritional status according to these three measures were compared.

Results

Mean age and median MNA-SF scores of the patients were 75±7.6 years and 12 points (min-max: 0-14) respectively. There were strongly positive correlations between MNA-SF scores with BMI and CC, with BMI and HGS, and with CC and HGS (r=0.938 p<0.001, r=0.938 p<0.001, r=0.914 p<0.001, respectively). Substantial agreement in nutritional status of the patients were seen between MNA-SF groups with BMI and CC, with CC and HGS, and with BMI and HGS (kappa: 0.795 p<0.001, kappa: 0.709 p<0.001, and kappa: 0.760 p<0.001, respectively).

Conclusions

HGS might be considered instead of BMI in MNA-SF test to assess nutritional status of geriatric patients.

     

Association between nutritional status (MNA®-SF) and frailty (SHARE-FI) in acute hospitalised elderly patients

Objective

This study aimed to explore the association between the impaired nutritional status and frailty in acute hospitalised elderly patients by using two tools, the MNA®-SF (Mini Nutritional Assessment® short-form) and the SHARE-FI (Frailty Instrument for Primary Care of the Survey of Health, Ageing and Retirement in Europe).

Design

Cross-sectional study.

Setting

Acute hospitalised, community-dwelling elderly patients were recruited at internal medicine wards in Vienna, Austria.

Participants

133 men (39%) and women (61%) aged 74 (65–97) years.

Measurements

MNA®-SF was used to investigate malnutrition (<7 points) and patients at risk of malnutrition (8 to 11 points). By using the SHARE-FI, subjects were classified as frail, pre-frail or robust. A factor analysis was applied to identify overlaps between the MNA®-SF and SHARE-FI items. Internal consistency of different dimensions was assessed by using Cronbach’s Alpha.

Results

Malnutrition or risk of malnutrition was found in 76.7% of the total sample and in 46.8% of robust, in 69.0% of pre-frail, and in 93.0% of frail participants. Frailty or prefrailty was found in 75.9% of the total sample and in 45.1% of the subjects with no risk of malnutrition, in 80.9% of subjects at risk of malnutrition, and in 94.1% of malnourished patients. The two used tools show overlaps in three dimensions: (1) nutrition problems, (2) mobility problems and (3) anthropometric items with a moderate to strong internal consistency (Cronbach’s Alpha of 0.670, 0.834 and 0.946, respectively). 64.7% of the total sample (79.5% of frail and 87.9% of malnourished subjects) would participate in a home-based muscle training and nutritional intervention program.

Conclusions

This study underlines the association and the overlap between frailty and impaired nutritional status. There is a high readiness to participate in a program to tackle the problems associated with malnutrition and frailty, especially in those, who would benefit most from it.     

Nutritional status of community-dwelling elderly with newly diagnosed Alzheimer’s disease: Prevalence of malnutrition and the relation of various factors to nutritional status

Objetives

To determine the prevalence of malnutrition and its relation to various factors in community-dwelling elderly with newly diagnosed Alzheimer’s disease (AD).

Design

Retrospective crosssectional study.

Setting

Memory clinic in a rural part of the Netherlands.

Participants

312 Community-dwelling AD patients, aged 65 years or older, were included.

Measurements

At the time the diagnosis AD was made, socio-demographic characteristics and data on nutritional status (Mini Nutritional Assessment (MNA)), cognitive function (Mini Mental State Examination (MMSE), Cambridge Cognitive Examination (Camcog)), functional status (Interview for Deterioration in Daily Living Activities in Dementia (IDDD), Barthel Index (BI)) and behaviour (Revised Memory and Behaviour Problems Checklist (RMBPC)) were assessed. Characteristics of well-nourished patients (MNA score >23.5) were compared to characteristics of patients at risk of malnutrition (MNA score 17–23.5). Linear regression analysis was performed to assess the effect of various factors on nutritional status.

Results

The prevalence of malnutrition was 0% and 14.1% was at risk of malnutrition. AD patients at risk of malnutrition were more impaired in basic and complex daily functioning than well-nourished AD patients (median IDDD score 41.5 [25th–75th percentile 38.8–48.0] versus median IDDD score 40.0 [25th–75th percentile 37.0–43.0], p = 0.028). The degree of impairment in basic and complex daily functioning (IDDD) was independently related to nutritional status (MNA) (p = 0.001, B = ?0.062).

Conclusion

One in seven community-dwelling elderly with newly diagnosed AD is at risk of malnutrition. The degree of impairment in daily functioning is independently related to nutritional status. Therefore, assessment of the nutritional status should be included in the comprehensive assessment of AD patients. The relation between daily functioning, nutritional status and AD warrants further investigation.
