Validation of the Abridged Patient-Generated Subjective Global Assessment as a Screening Tool for Malnutrition in an Outpatient Oncology Setting

Nutrition impact symptoms and the risk of malnutrition in people with Parkinson's disease: A cross-sectional study

BACKGROUND

People with Parkinson's disease (PD) often experience symptoms that affect their ability to eat. This may contribute to weight loss and increased risk of malnutrition. The present study aimed to quantify the extent of nutrition impact symptoms (NIS) in the population and a scoring system of NIS was incorporated in the tool used to identify malnutrition.

METHODS

In this cross-sectional study, members of the Norwegian Parkinson's Association, with any PD diagnosis and stage of illness, were invited to respond to an online 24-item questionnaire. Questions from two validated questionnaires, comprising the abridged Patient-Generated Subjective Global Assessment (aPG-SGA) and the Radboud Oral Motor Inventory for Parkinson's disease (ROMP), were adapted to an online format.

RESULTS

The questionnaire was sent to 3047 members, of which 508 persons (17%) responded (61% men). In total, 59% were categorised as well-nourished, 34% at risk of malnutrition and 6.5% as malnourished. One quarter of all participants reported symptoms that affected food intake. The most frequent symptoms were constipation (14.2%) and dry mouth (13.4%). Malnourished participants reported a mean ± SD of 3.4 ± 1.4 symptoms versus 0.1 ± 0.3 per well-nourished participant. Malnourished participants had more swallowing problems than well-nourished participants, with a mean ± SD total ROMP score of 15.5 ± 6.0 versus 9.0 ± 2.9 (p < 0.001). As the number of points in the ROMP score increased by one, the points in the aPG-SGA score increased with 37% (95% confidence interval = 0.309-0.428).

CONCLUSIONS

Risk of malnutrition was largely related to NIS, especially dysphagia in people with PD. Symptoms affecting food intake should be systematically mapped and treated in conjunction with PD to prevent malnutrition.

The abridged patient-generated subjective global assessment is a useful tool for early detection and characterization of cancer cachexia

Cancer cachexia (CC) is a syndrome characterized by wasting of lean body mass and fat, often driven by decreased food intake, hypermetabolism, and inflammation resulting in decreased lifespan and quality of life. Classification of cancer cachexia has improved, but few clinically relevant diagnostic tools exist for its early identification and characterization. The abridged Patient-Generated Subjective Global Assessment (aPG-SGA) is a modification of the original Patient-Generated Subjective Global Assessment, and consists of a four-part questionnaire that scores patients' weight history, food intake, appetite, and performance status. The purpose of this study was to determine whether the aPG-SGA is associated with both features and clinical sequelae of cancer cachexia. In this prospective cohort study, 207 advanced lung and gastrointestinal cancer patients completed the following tests: aPG-SGA, Edmonton Symptom Assessment System, handgrip strength, a complete blood count, albumin, apolipoprotein A and B, and C-reactive protein. Ninety-four participants with good performance status as assessed by the Eastern Cooperative Oncology Group Performance Status completed additional questionnaires and underwent body composition testing. Of these, 68 patients tested for quadriceps strength and completed a 3-day food recall. Multivariable regression models revealed that higher aPG-SGA scores (≥9 vs 0 to 1) are significantly associated (P<0.05) with the following: unfavorable biological markers of cancer cachexia, such as higher white blood cell counts (10.0 vs 6.7×10(9)/L; lower hemoglobin (115.6 vs 127.7 g/L), elevated C-reactive protein (42.7 vs 18.2 mg/L [406.7 vs 173.3 nmol/L]); decreased anthropometric and physical measures, such as body mass index (22.5 vs 27.1); fat mass (14.4 vs 26.0 kg), handgrip (24.7 vs 34.9 kg) and leg strength; an average 12% greater length of hospital stay; a dose reduction in chemotherapy; and increased mortality. Given its association with the main features of cancer cachexia and its ease of use, the aPG-SGA appears to be a useful tool for detecting and predicting outcomes of cancer cachexia. Additional research is required to determine what impact the aPG-SGA has on quality of care when used in the clinical setting.

The impact of nutritional status, physical function, comorbidity and early versus late start in dialysis on quality of life in older dialysis patients

BACKGROUND

For the majority of the older patients in dialysis, the treatment will be lifelong. Thus, quality of life (QoL) is a crucial outcome. Our aim was to assess the QoL of older Norwegian dialysis patients and to investigate the impact of early (estimated glomerular filtration rate, eGFR ≥10 mL/min) versus late (eGFR <10 mL/min) start in dialysis, comorbidity, nutritional status and physical capacity.

METHODS

A self-report questionnaire including SF-36 (QoL) and the Subjective Global Assessment (SGA; nutritional status) was mailed to all patients (n = 320) ≥75 years registered in the Norwegian Renal Registry (NRR) as being in dialysis by September 2009. Reply was received from 233 patients (73%). Medical data including comorbidities and eGFR at dialysis start (obtained for 194 patients) were retrieved from the NRR. Functional capacity was determined from the SGA.

RESULTS

Compared to reports from younger dialysis patients, our patients scored poorer on all SF-36 subscales. Early start in dialysis was registered for 52 patients, 142 patients started late, 51.4% were well nourished (SGA A), 32.3% moderately malnourished (SGA B) and 16.4% were severely malnourished (SGA C). No significant association between any SF-36 scores and early versus late start, nutritional status or comorbidity was found. Better physical function was significantly associated with better scores on all SF-36 scales.

CONCLUSIONS

Our results indicate that physical function is important to all QoL aspects. Increased focus on physical rehabilitation seems pertinent. Early start of dialysis treatment was not associated with better long term QoL scores.
