Disease-related malnutrition in hospitalized chronic patients with complex needs

Sex differences in clinical presentation, treatment response, and side effects of nutritional therapy among patients at nutritional risk: a secondary analysis of the randomized clinical trial EFFORT

BACKGROUND

Considering sex-specific factors has become an increasingly recognized area for research and practice, in the field of clinical nutrition, there is insufficient evidence regarding differences in clinical presentation, treatment response, and side effects of nutritional therapy among female and male patients.

METHODS

This secondary analysis investigated differences among female and male patients at risk for malnutrition regarding initial presentation, clinical outcomes, and treatment response in patients included in the Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), a randomized controlled trial comparing individualized nutritional support to usual care.

RESULTS

Of 2028 patients included in the trial, 964 were females and 1064 were males. The nutritional history and clinical presentation of female patients was different: they consumed less food and had a greater loss of appetite than the male population. Male patients had higher risk for mortality at 180 d [27% compared with 19%; adjusted hazards ratio (HR): 1.35; 95% CI: 1.12, 1.63] and further adverse clinical outcomes. However, there was no difference in the effect of nutritional support on mortality among female and male patients (HR: 0.76; 95% CI: 0.45, 1.27, compared with HR: 0.81; 95% CI: 0.54, 1.21, respectively; P-interaction = 0.939).

CONCLUSIONS

Results of this multicenter randomized trial suggest that multimorbid female inpatients have a different clinical presentation and are more prone to loss of appetite and reduced daily dietary intake than male inpatients. Importantly, the favorable response to nutritional interventions was similar in both sexes. This trial was registered at clinicaltrials.gov as NCT02517476.

Prevention and Management of Malnutrition in Patients with Chronic Obstructive Pulmonary Disease: A Scoping Review

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is linked to altered nutritional status due to increased catabolism, leading to muscle mass loss. This study aims to identify and map available evidence regarding multidisciplinary interventions focused on prevention, diagnosis and nutrition education, as well as the role of diet, to prevent and manage malnutrition in patients with COPD.

METHODS

A scoping review was conducted using the Cochrane, PubMed/Medline, CINAHL, Embase, Scopus, and Web of Science databases. This study adhered to the Arksey and O'Malley framework and JBI methodology.

RESULTS

Of the 1761 records identified, 15 were included. Evidence suggests that the Malnutrition Universal Screening Tool and Mini Nutritional Assessment are the most suitable screening scale. Guidelines have highlighted that personalized nutritional counseling is a very common intervention as it allows for a consideration of all physical, psychological, and social aspects of the patient.

CONCLUSIONS

The role of healthcare professionals is crucial in the early identification of nutrition-related issues and in educating patients about the prevention and management of malnutrition, both in hospital and community settings. Key aspects include early malnutrition detection, personalized counseling and patient education, and a multidisciplinary approach. These findings provide a foundation for developing of targeted patient educational initiatives to improve the nutritional management of COPD patients.

Management of disease-related malnutrition: a real-world experience with a novel concentrated high-protein energy-dense oral nutritional supplement

OBJECTIVE

Despite the availability of a wide range of oral nutritional supplements (ONS) offerings, individuals with malnutrition are still struggling to meet their nutritional targets. A new concentrated and high-protein energy-dense ONS (≥2.1 kcal/mL;32 g protein/200 mL) with high-quality protein (60% whey protein) has emerged as a pivotal formula to reach the patient's energy-protein requirements, enhance compliance, and maximize stimulation of muscle protein synthesis, key factors driving better nutritional, functional, and clinical outcomes. The purpose of this article is to provide our clinical experience using this new nutritionally concentrated ONS as a therapeutic strategy for patients with DRM.

METHODS

Three clinical cases have been examined using new assessment procedures and a new form of nutritional therapy, and their impact on the nutritional and functional outcomes in patients with moderate-to-severe DRM.

RESULTS

A tailored individualized nutritional interventions improved anthropometric, biochemical, and functional outcomes (Case 1,2, and 3) assessed using hand grip strength, bioimpedance and muscle ultrasound, and as well as good gastrointestinal tolerance (Case 1) and compliance to the ONS in patients with DRM (Case 1,2,3).

CONCLUSION

The use of this novel high-protein energy-dense formula with high-quality protein source (≥2.1 kcal/mL; 32 g protein/200 mL; 60% whey protein) overcome common practical challenges in the medical nutrition therapy of patients with DRM, either because these patients require a highly concentrated formulation to meet nutritional requirements due to loss of appetite, lack of interest in food, and high caloric-protein needs due to disease, and a large quantity and quality of protein to optimize muscle recovery due to sarcopenia, common in patients with moderate-severe malnutrition.

Improving nutrition care and diet intake for hospitalised older people at risk of malnutrition through a nurse-driven mealtime assistance bundle

BACKGROUND

Poor dietary intake is common in hospitalised older people. A targeted mealtime intervention is needed to improve nutrition care and dietary intake, especially for those at risk of malnutrition.

OBJECTIVES

This quality improvement project designed, implemented and evaluated a mealtime assistance bundle consisting of care measures driven by the hospital nursing team. The aims were to improve the mealtime care process to promote dietary intake of the hospitalised older people and to improve nursing staff's knowledge, attitude and practice in malnutrition.

METHODS

This project adopted a pre-post design, targeting older people aged 65 years and above, who were admitted to a general medical unit in a regional hospital in Singapore. A mealtime assistance bundle consisting of seven care measures, using the acronym CANFEED, was implemented for older adults at risk of malnutrition. Outcome measures on the amount of dietary intake during meals through chart reviews and surveys of nursing staff using Malnutrition Knowledge, Attitudes and perceived Practices (M-KAP) questionnaire were performed before and after implementation.

RESULTS

There were fewer older adults with poor intake in the post-implementation group than the pre-implementation group. Among those at risk of malnutrition, older adults in the post-implementation group had higher average intake of all provided meals as well as the protein-dense main dish. Significant improvements were noted in the total scores rated by the nursing staff in both the Knowledge-Attitude subscale and Practice subscale of the M-KAP questionnaire.

CONCLUSIONS

Integrating a nurse-driven mealtime assistance bundle into usual care may have positive outcomes on nutritional intake of hospitalised older people at risk of malnutrition, and on knowledge, attitude and practice of hospital nurses in nutrition care.

IMPLICATIONS FOR PRACTICE

Nurses play a critical role in nutrition care for hospitalised older people. Continuing efforts to improve nutritional intake of hospitalised older people should focus on staff education, building a multidisciplinary food-promoting culture and patient, family and community empowerment. More efficient clinical processes incorporating information technology with the EMR to support better nutrition care of the hospitalised older people are needed.

Time to act! - A cross-sectional study on how nutritional risk increases during hospitalization and associates with worse outcome

BACKGROUND & AIMS

Nutritional risk is prevalent, and it develops negatively during hospital stay. The aim of this cohort study was to assess the association of nutritional risk with total costs of hospital care, length of stay, and in-hospital mortality.

METHODS

Cross-sectional study with hospitalized patients (n = 3053). Nutritional risk screening 2002 and outcome were investigated. Chi-square, Fisher, and Mann-Whitney tests, univariable and multivariable generalized linear and binary logistic regression models were used.

RESULTS

Nutritional risk was detected in 18% (184/1024) of those patients assessed at admission while the number of patients at risk increased 3-fold (47%,152/265) in those screened 14 days after admission (odds ratio 6.25; 95% CI 4.58-8.53, p < 0.001). Nutritionally at-risk patients had 5.6 days longer length of stay (p < 0.001) and 9% higher adjusted total costs compared with non-risk patients (p < 0.001). Adjusted overall risk for in-hospital mortality was 4.4 (95% CI 2.44-7.92, p < 0.001) for patients at nutritional risk. The screening rate was between 52% and 68%, and only 4% of the nutritionally at-risk patients had dietitian consultation during their hospital stay.

CONCLUSIONS

The number of patients with nutritional risk increased clearly during hospitalization associating with a four times higher in-hospital mortality and substantially increased hospital costs. The results demonstrate that the nutritional risk and its detrimental influence on the outcome increases during hospitalization emphasizing the importance to screen patients at admission and repeated weekly.

Risks of undernutrition and depression in hospitalized patients: A cross-sectional study

Undernutrition in hospitalized patients is a significant healthcare burden worldwide. Depression is a major global health problem characterized by symptoms such as altered mood, loss of interest and pleasure, and impairment in cognitive and physical functions. Patients hospitalized for medical conditions have a higher risk of depression than the general population. The purpose of this study was to explore the relationship between undernutrition risk and depression risk in hospitalized patients. The design of this study was an observational cross-sectional analytic. A questionnaire form created by the investigator including sociodemographic data, dietary patterns, presence of chronic diseases and anthropometric measurements, Nutritional Risk Screening and Patient Health Questionnaire-2 were applied to the patients. All quantitative data were expressed as the median and interquartile range and qualitative data were expressed as numbers and percentage. Mann-Whitney U test and Kruskal-Wallis test were used to analyze nonparametric data; Chi-square and Fisher Exact test were used to analyze qualitative data. P < .05 was considered statistically significant. A total of 308 patients who met the criteria were reached. Undernutrition was detected in 28.6% of the participants, and depression was present in 37.3%. A statistically significant relationship was found between the risk of undernutrition and the risk of depression, with individuals without a risk of depression being found to have a lower risk of undernutrition. (P < .001). The risk of undernutrition was found to increase with advancing age. Moreover, individuals with higher values for arm muscle area, arm muscle circumference, mid-upper arm circumference, triceps skinfold thickness, calf circumference, and body mass index had a lower risk of undernutrition. No relationship was found between gender and the risk of depression. However, a statistically significant relationship was observed between age and the risk of depression, indicating that older patients had a higher risk of depression. In this study, a statistically significant relationship was found between the risk of undernutrition and the risk of depression in hospitalized patients. It was observed that the risk of undernutrition was lower in individuals without risk of depression.

The Prevalence and Impact of Nutritional Risk and Malnutrition in Gastrointestinal Surgical Oncology Patients: A Prospective, Observational, Multicenter, and Exploratory Study

A prospective, observational, multicenter, and exploratory study was conducted in 469 gastrointestinal cancer patients undergoing elective surgery. The Malnutrition Universal Screening Tool (MUST) and the Global Leadership Initiative on Malnutrition (GLIM) criteria were used to assess nutritional risk. On admission, 17.9% and 21.1% of patients were at moderate (MUST score 1) and severe (MUST score ≥ 2) nutritional risk, respectively. The GLIM criteria used in patients with a MUST score ≥ 2 showed moderate malnutrition in 35.3% of patients and severe in 64.6%. Forty-seven percent of patients with a MUST score ≥ 2 on admission had the same score at discharge, and 20.7% with a MUST score 0 had moderate/severe risk at discharge. Small bowel, esophageal, and gastric cancer and diabetes were predictors of malnutrition on admission. Complications were significantly higher among patients with a MUST score 1 or ≥2 either on admission (p = 0.001) or at discharge (p < 0.0001). In patients who received nutritional therapy (n = 231), 43% continued to have moderate/severe nutritional risk on discharge, and 54% of those with MUST ≥ 2 on admission maintained this score at discharge. In gastrointestinal cancer patients undergoing elective surgery, there is an urgent need for improving nutritional risk screening before and after surgery, as well as improving nutritional therapy during hospitalization.

Malnutrition and its association with the mortality in liver cirrhosis; a prospective nutritional assessment in two referral centers in Iran

INTRODUCTION

Liver cirrhosis is a chronic condition caused by different conditions including viral infection, alcoholism, and autoimmune disorders. Malnutrition is one of the complications of liver cirrhosis that is associated with poor outcomes. This study aimed to determine the association of malnutrition with mortality in liver cirrhosis patients.

METHODS

This prospective cross-sectional study was conducted on liver cirrhosis patients who were referred to two referral centers for liver disease in Tehran, Iran. Patients' information including demographics (age, gender, etiology of cirrhosis, alcohol and smoking history) in addition to triceps skinfold (TSF), mid-arm circumference (MAC), Child-Pugh score and Model for End-Stage Liver Disease (MELD) score were recorded in all patients. Patients were classified into A, B, and C categories based on the Subjective Global Assessment (SGA) questionnaire.

RESULTS

Among 121 participants (68.6%) were males and the mean age was 54.78. Viral infections were the most common etiology and 65 patients (56.2%) were in the classification A of Child-Pugh Score. TSF (P = 0.001) and MAC (P = 0.003) were significantly lower in SGA class C. The survival rate in SGA class C was significantly lower than other groups (P < 0.001; log-rank test). The risk of mortality in patients with SGA class A and B was 85% (HR value: 0.15; 95% CI: 0.02-0.87; P = 0.03) and 76% (HR value: 0.24; 95% CI: 0.06-0.83; P = 0.02) lower than those with SGA class C.

CONCLUSION

Anthropometric and SGA measure are two easy and accessible methods for assessing malnutrition and mortality in liver cirrhosis patients.

The syndromic triad of COVID-19, type 2 diabetes, and malnutrition

The coronavirus disease 2019 (COVID-19) pandemic challenges our collective understanding of transmission, prevention, complications, and clinical management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Risk factors for severe infection, morbidity, and mortality are associated with age, environment, socioeconomic status, comorbidities, and interventional timing. Clinical investigations report an intriguing association of COVID-19 with diabetes mellitus and malnutrition but incompletely describe the triphasic relationship, its mechanistic pathways, and potential therapeutic approaches to address each malady and their underlying metabolic disorders. This narrative review highlights common chronic disease states that interact epidemiologically and mechanistically with the COVID-19 to create a syndromic phenotype-the COVID-Related Cardiometabolic Syndrome-linking cardiometabolic-based chronic disease drivers with pre-, acute, and chronic/post-COVID-19 disease stages. Since the association of nutritional disorders with COVID-19 and cardiometabolic risk factors is well established, a syndromic triad of COVID-19, type 2 diabetes, and malnutrition is hypothesized that can direct, inform, and optimize care. In this review, each of the three edges of this network is uniquely summarized, nutritional therapies discussed, and a structure for early preventive care proposed. Concerted efforts to identify malnutrition in patients with COVID-19 and elevated metabolic risks are needed and can be followed by improved dietary management while simultaneously addressing dysglycemia-based chronic disease and malnutrition-based chronic disease.

[Evaluation of improved nutritional status in patients over 60 years with 6-month follow-up by a nutritionist in a hospital setting in Almería. The MOR-NUT study]

BACKGROUND

non-institutionalized elderly patients who are prescribed an oral nutritional supplement (ONS) often have difficulties with compliance, which leads to physical deterioration and increases the risk of malnutrition.

OBJECTIVE

to assess improvement in the nutritional status of patients over 60 years of age, using the Mini Nutritional Assessment (MNA) score after the intervention of a nutritionist during a 6-month follow-up of malnourished patients with an indication for ONS. To demonstrate that the intervention of a nutritionist provides long-term improvements in the nutritional status of malnourished patients who are taking an ONS.

RESULTS

the nutritional intervention significantly improved BMI (from 22.9 ± 4.5 to 24.0 ± 4.1; p = 0.001) and the MNA score (from 14.7 ± 4.4 to 20.4 ± 5.8; p < 0.001) of the patients, as well as their perception of health (measured by VAS).

CONCLUSIONS

the nutritional advice provided by a nutritionist to patients who were taking an ONS provided a high rate of adherence to treatment, which resulted in improvement in the nutritional status of patients.

Compliance with a high-protein and energy-dense oral nutritional supplement in patients with disease-related malnutrition: a randomized open-label crossover trial

Introduction

Patient compliance with oral nutritional supplements (ONS) is not optimal for meeting energy and nutritional requirements in a high proportion of patients with disease-related malnutrition (DRM). Energy density or prescribed volume of ONS may impact compliance.

Methods

A randomized, open-label crossover trial was conducted in outpatients with DRM to compare compliance with a high energy-dense ONS (edONS, 2.4 kcal/mL) and a reference ONS (heONS, 2.0 kcal/mL; NCT05609006). Patients were randomly assigned to two 8-week treatment sequences of four-weeks periods: edONS + heONS (sequence A) or heONS + edONS (sequence B). Patients daily reported the amount of product left over gastrointestinal tolerance and satisfaction with ONS. A non-inferiority analysis was performed to compare the compliance rate (percentage of consumed energy over the prescribed) for each period and sequence.

Results

Fifty-three patients were assigned to sequence A and 50 to sequence B (55.7 ± 13.9 years, 37.0% female, 67.1% oncology patients). In sequence A, the compliance rates were 88.6% ± 14.3% vs. 84.1 ± 21.8% (p = 0.183), while in sequence B, they were 78.9% ± 23.8% vs. 84.4% ± 21.4% (p < 0.01). In both sequences, the lower range of the confidence interval for compliance with edONS was greater than the non-inferiority threshold (for sequence A Δ_Comp^A was 4.5% [95% CI, -2.0% to 10.0%], and for sequence, B Δ_Comp^B was 5.6% [95% CI, -3.0% to 14.0%]). The total discarded cost for each ONS was higher for heONS than edONS, being the difference statistically significant in sequence B. BMI increased slightly and not significantly in both sequences, and the percentage of patients with severe malnutrition was reduced. The frequency of gastrointestinal symptoms was low for both sequences, and satisfaction with ONS was slightly higher for edONS.

Conclusion

Our findings highlight that edONS was non-inferior to heONS in terms of consumed energy over the prescribed, with a lower amount of edONS discarded, which suggests a higher efficiency of edONS.

Impact of nutrition status and body mass index on mortality in hospitalized general medical patients: A prospective observational study

BACKGROUND

Malnutrition and low body mass index (BMI) are risk factors for mortality in hospitalized patients. Data substantiating this are unavailable for hospitalized general medical patients in our setting. We studied the prevalence of malnutrition among patients admitted to general medical wards in a tertiary care hospital and its role as a risk factor for 1-month mortality. We also investigated the association of BMI with mortality.

METHODS

In this prospective observational study, nutrition assessment using Subjective Global Assessment (SGA) and anthropometric measurements was performed in 395 hospitalized general medical patients. Charlson Comorbidity Index (CCI) and Modified Early Warning System (MEWS) score were calculated. Clinical course and vital status at 1 month after discharge was noted. Factors associated with mortality were identified using logistic regression.

RESULTS

The mean age of the study population was 46.2 + 16.1 years; 247 (62.5%) were males. Of 395 patients, 129 (32.7%) belonged to SGA A, 155 (39.2%) to SGA B, and 111 (28.1%) to SGA C. Mean (±SD) BMI was 23.38 (±5.33); 141 (35.6%) were obese. Mortality was observed in 61 (15.4%) patients. Patients in the lowest BMI quartile had the lowest mortality. The adjusted regression analysis showed that higher age and MEWS scores were independently associated with mortality. Severe malnourishment (SGA C) was another important predictor. Further, the odds of death increased consistently across the consecutive BMI quartiles.

CONCLUSION

Higher age, higher MEWS scores, severe malnourishment, and higher BMI scores were independent risk factors for 1-month mortality in hospitalized general medical patients.

European mature adults and elderly are moving closer to the Mediterranean diet-a longitudinal study, 2013-19

BACKGROUND

The decreasing adherence in Mediterranean Diet (M.D.) during the last decades has been attributed to social, cultural and economic factors. However, recent efforts to improve dietary habits and the economic improvement might be reversing this trend. We analyze the changes in M.D. adherence between 2013 and 2019 among a sample of European mature adults and the elderly.

METHODS

Using data from the Survey of Health, Ageing and Retirement in Europe for adults over 50 years old, we designed a longitudinal cohort study with a sample of participants from waves 5 (2013) and 8 (2019/20). Logistic regressions were used to model the consumption of M.D. adherence as a function of the year. We then stratified the analyses by education, age and transitions in economic status, employment and self-perceived health.

RESULTS

There was in 2019/20 a significant increase in the M.D. adherence (10.8% vs. 14.3%, OR = 1.367, P < 0.01). The rise was mainly related to the decrease of meat and fish (38.4% vs. 30.5%, OR = 0.703, P < 0.01) and growth of legumes and eggs intake (36.3% vs. 41.8%, OR = 1.260 P < 0.01). The results were consistent in all European regions and most sociodemographic groups. Younger people with higher income and education had a greater rise in adherence.

CONCLUSIONS

Our analysis shows a generalized growth in adherence to the M.D. across most socioeconomic subpopulations and countries in Europe, suggesting a shift to healthier diet patterns. The more noticeable increase among affluent, educated and healthy respondents, may further entrench dietary and health inequalities.

Nutritional Status and Potentially Inappropriate Medications in Elderly

(1) Background: The association between polypharmacy and malnutrition has been investigated in several studies; however, few of these specifically deepened the relationship between potentially inappropriate medication and malnutrition. With a descriptive approach, the primary aim of our study was to evaluate the impact of the nutritional status, assessed with the Mini Nutritional Assessment (MNA), on potentially inappropriate medications (PIM), estimated 10-year survival, and the risk of adverse drug reactions in elderly patients; the secondary aim was to evaluate how the Screening Tool of Older People’s Prescriptions (STOPP), Screening Tool to Alert to Right Treatment (START), and BEERS 2019 criteria identify PIM compared to nutritional status. (2) Methods: In this study, 3091 subjects were enrolled, of whom 2748 (71.7%) were women; the median age was 80 years, with an interquartile range between 75 and 85 years of age. The subjects were assessed at the outpatient service for frail older people of the University Hospital of Cagliari. The study population was evaluated for their: MNA, Charlson Comorbidity Index, 10-year survival estimation, BEERS 2019, STOPP and START criteria, and ADR Risk scores. (3) Results: We divided the study population into three groups: MNA1 (MNA score ≥ 24), MNA2 (23.5−17), and MNA3 (<17): the severity of comorbidities, STOPP and START alerts, and BEERS 2019 criteria were significantly worse in both MNA2 and MNA3 compared to MNA1—with the exception of BEERS “non-anti-infective medications that should be avoided or have their dosage reduced with varying levels of kidney function in older adults”. Moreover, the estimated 10-year survival was significantly higher in MNA1 than in MNA2 and MNA3, and also in MNA2 compared to MNA3. Finally, the ADR risk scores were significantly lower in MNA1 than in MNA2 and MNA3. (4) Conclusions: Our study demonstrated the association between nutritional status and PIM checked with the BEERS 2019 criteria, and, for the first time, with the STOPP and START criteria.

Perioperative Nutritional Support: A Review of Current Literature

Since the beginning of the practice of surgery, the reduction of postoperative complications and early recovery have been two of the fundamental pillars that have driven the improvement of surgical techniques and perioperative management. Despite great advances in these fields, the rationalization of antibiotic prophylaxis, and other important innovations, postoperative recovery (especially in elderly patients, oncological pathology or digestive or head and neck surgery) is tortuous. This can be explained by several reasons, among which, malnutrition has a major role. Perioperative nutritional support, included within the ERAS (Enhanced Recovery After Surgery) protocol, has proven to be a main element and a critical step to achieve better surgical results. Starting with the preoperative nutritional assessment and treatment in elective surgery, we can improve nutritional status using oral supplements and immunomodulatory formulas. If we add early nutritional support in the postoperative scenario, we are able to significantly reduce infectious complications, need for intensive care unit (ICU) and hospital stay, costs, and mortality. Throughout this review, we will review the latest developments and the available literature.

Malnutrition management of hospitalized patients with diabetes/hyperglycemia and COVID-19 infection

Diabetes mellitus and/or hyperglycemia are highly prevalent medical conditions in patients hospitalized for coronavirus disease 2019 (COVID-19) and are associated with adverse outcomes. In addition, COVID-19 itself can provoke fluctuating and high glucose levels that can be difficult to manage upon hospitalization. Hospitalized patients with COVID-19 are at high risk of malnutrition due to an increase in nutritional requirements and a severe acute inflammatory response. The management of patients with diabetes/hyperglycemia and COVID-19 is challenging and requires a specific nutritional approach, the purpose of which is to fulfill the nutritional requirements while maintaining an optimal glycemic control. In this study, an expert group of nutritional endocrinologists carried out a qualitative literature review and provided recommendations based on evidence and guidelines, when available, or on their own experience. The optimal care based on these recommendations was compared with the routine bedside care as reported by a panel of physicians (mainly, endocrinologists, geriatricians, and internists) treating patients with diabetes/hyperglycemia and COVID-19 in their daily practice. Early screening and diagnosis, a diabetes-specific therapeutic approach, and a close malnutrition monitoring are essential to improve the clinical outcomes of these patients. In conclusion, the proposed recommendations are intended to provide a useful guide on the clinical management of malnutrition in patients with COVID-19 and diabetes/hyperglycemia, in order to improve their outcomes and accelerate their recovery. The comparison of the recommended optimal care with routine clinical practice could aid to identify gaps in knowledge, implementation difficulties, and areas for improvement in the management of malnutrition in this population.

Investigation of Zinc Supplement Impact on the Serum Biochemical Parameters in Pulmonary Tuberculosis: A Double Blinded Placebo Control Trial

BACKGROUND

Zinc (Zn) is nutritionally essential trace element, and thus deficiency may severely affect human health. The results of cross-sectional studies indicate that micronutrient deficiencies are common in patients with tuberculosis. Our goal is to investigate whether Zn supplementation can increase the effects of anti-TB treatment or not.

METHODS

Patients with newly diagnosed tuberculosis were divided in to 2 groups. One group (n= 37) received capsule contains 50 mg of elemental zinc (as zinc sulfate) for 6 months every other day (micronutrient group) and Group II (n= 37) received placebo. Both groups received the same anti-tuberculosis treatment recommended by the WHO. Clinical examination, BMI, chest X-ray, direct sputum examination, assessment of serum zinc levels (by atomic absorption spectrophotometry), and biochemical markers serum concentration (by using an RA1000 AutoAnalyzer) were carried out before and after 2- and 6-months anti-tuberculosis treatment.

RESULTS

Plasma zinc concentrations in the micronutrient group was higher than placebo group After treatment. In the placebo group increasing in SGOT and SGPT concentrations were significantly higher than micronutrient group after 2 months of treatment (p< 0.05). The significant changes (p< 0.05) were observed on the serum levels of total protein, albumin. Alkaline phosphatase (ALP) levels, serum creatinine, uric acid and urea in groups were not significantly different.

CONCLUSION

Zinc supplementation results in earlier sputum smear conversion in the micronutrient group during the first 6 weeks. Increased body weight and serum zinc and serum albumin and decrease in total protein was observed in the micronutrient group.

SeDREno study - prevalence of hospital malnutrition according to GLIM criteria, ten years after the PREDyCES study

BACKGROUND & AIMS

the last large multicenter study on disease-related malnutrition (DRM) in Spain (the PREDyCES study) showed a 23.7 % prevalence of malnutrition, according to the Nutritional Risk Screening (NRS-2002) tool. The main objective of the SeDREno study was to assess the prevalence of hospital malnutrition upon admission, according to GLIM criteria, ten years later.

METHODS

a cross-sectional, observational, multicenter study in standard clinical practice, conducted in 17 hospitals during a period of five to seven days. Patients were initially screened using the Malnutrition Universal Screening Tool (MUST), and then assessed using the GLIM criteria for diagnosis and severity grading.

RESULTS

a total of 2,185 patients, 54.8 % males, mean age 67.1 (17.0) years (50.2 % aged ≥ 70 years), were evaluated. Malnutrition was observed in 29.7 % of patients according to GLIM criteria (12.5 % severe, 17.2 % moderate). In patients ≥ 70 years malnutrition was observed in 34.8 %. The clinical conditions significantly associated with a higher prevalence of malnutrition were dysphagia (47.6 %), cognitive impairment (43.4 %), cancer (39.1 %), gastrointestinal disease (37.7 %), diabetes (34.8 %), and cardiovascular disease (33.4 %). The multivariate analysis revealed that gender, BMI, diabetes, cancer, gastrointestinal disorders, and polypharmacy were the main independent factors associated with DRM. Malnutrition was associated with an increase in length of hospital stay and death (p < 0.001).

CONCLUSIONS

DRM in admitted patients has increased in Spain in the last 10 years paralleling ageing of the population. In the SeDREno study almost one in three patients are malnourished. A systematic assessment of nutritional status allows early detection and implementation of nutritional interventions to achieve a better clinical outcome.

Maternal Characteristics Mediating the Impact of Household Poverty on the Nutritional Status of Children Under 5 Years of Age in Bangladesh

OBJECTIVES

We explored the maternal characteristics that mediate the effect of household poverty on childhood undernutrition.

METHODS

We used the population-based Bangladesh Demographic Health Survey data from 2014 for demographic characteristics, child and maternal factors.

RESULTS

Of the 7173 under-5 children, 3456 (48.2%) had undernutrition. The prevalence of undernutrition was less common in wealthy households (poorest vs richest: adjusted prevalence ratio [aPR] = 1.37), mothers having history of antenatal care (ANC) visits (no visit vs ≥ 4 visits: aPR = 1.22), maternal higher education (no education vs higher education: aPR = 1.54), and mothers with good nutritional status (underweight vs healthy: aPR = 1.13). The risk of undernutrition (37.1%) was attributed to household wealth, mediated 55% by maternal factors; of which 20% by maternal education, 21% by ANC visits, and 14% by maternal nutritional status.

CONCLUSIONS

Our study findings outlined higher maternal education, ≥ 4 ANC visits and good maternal nutritional status in mediating the impact of household wealth on childhood nutrition.

The Burden of Malnutrition and Fatal COVID-19: A Global Burden of Disease Analysis

Background: Although reasonable to assume, it is not yet clear whether malnourished countries are at higher risk for severe or fatal coronavirus disease 2019 (COVID-19). This study aims to identify the countries where prevalent malnutrition may be a driving factor for fatal disease after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Methods: Using estimates from the Global Burden of Disease 2019, country-level burden of malnutrition was quantified using four indicators: death rates for child growth failure (underweight, stunting, and/or wasting) and years lived with disability (YLD) attributed to iron and vitamin A deficiencies and high body mass index (BMI). Global mortality descriptors of the ongoing COVID-19 pandemic were extracted from the European Centre for Disease Prevention and Control, and case fatality ratios (CFRs) were calculated introducing a lag time of 10 weeks after the first death of a confirmed case. Bivariate analyses for 172 countries were carried out for malnutrition indicators and fatal COVID-19. Correlations between burden indicators were characterized by Spearman's rank correlation coefficients (ρ) and visually by scatterplots. Restricted cubic splines and underlying negative binomial regressions adjusted for countries' age-structure, prevalent chronic comorbidities related to COVID-19, population density, and income group were used to explore non-linear relationships. Results: Stratified by the World Bank income group, a moderate positive association between YLD rates for iron deficiency and CFRs for COVID-19 was observed for low-income countries (ρ = 0.60, p = 0.027), whereas no clear indications for the association with child growth failure, vitamin A deficiency, or high BMI were found (ρ < 0.30). Countries ranking high on at least three malnutrition indicators and presenting also an elevated CFR for COVID-19 are sub-Saharan African countries, namely, Angola, Burkina Faso, Chad, Liberia, Mali, Niger, Sudan, and Tanzania, as well as Yemen and Guyana. Conclusions: Population-level malnutrition appears to be related to increased rates of fatal COVID-19 in areas with an elevated burden of undernutrition, such as countries in the Sahel strip. COVID-19 response plans in malnourished countries, vulnerable to fatal COVID-19, should incorporate food security, nutrition, and social protection as a priority component in order to reduce COVID-19 fatality.
