Exploring adult inpatients' perceptions, understanding and preferences regarding the term 'malnutrition': A qualitative study.

AIMS: To explore adult inpatients' perceptions, understanding and preferences regarding the term 'malnutrition' and to identify the terms that adult inpatients report are used by themselves and health workers to describe malnutrition. DESIGN: This qualitative study was conducted using data collected for a separate qualitative study that investigated factors that influence the dietary intake of long-stay, acute adult inpatients. METHODS: Semi-structured interviews were conducted with a purposive sample of current inpatients. Data were analysed using inductive content analysis. RESULTS: Nineteen interviews were included (mean age 64 years (standard deviation ±17), 10 female (53%), 12 malnourished (63%)). Four categories were identified. 'Variation in patients' recognition of malnutrition' represents the differing abilities of patients to understand and identify with the term 'malnutrition'. 'Recognising individuals' needs and preferences' highlights patients' varying beliefs regarding whether 'malnutrition' is or is not an appropriate term and participants' suggestion that health workers should tailor the term used to each patient. 'Inconsistencies in health workers' and patients' practice regarding malnutrition terminology' encapsulates the multiple terms that were used to describe malnutrition by health workers and patients. 'Importance of malnutrition education' summarises patients' views that health workers should provide patient education on malnutrition prevention, management and complications. CONCLUSION: Findings highlight variations in patients' perceptions and understanding of the term 'malnutrition' and differences in the terms used by patients and health workers to describe malnutrition. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The terminology used by health workers to describe malnutrition risk or malnutrition to their patients can influence patients' recognition of their nutritional status and thus the multidisciplinary management of the condition. To ensure that patients receive information about their malnutrition risk or diagnosis in a way that meets their needs, health workers' practices must be revised. To do this, it is imperative to conduct further collaborative research with patients and health workers to identify optimum terms for 'malnutrition' and how health workers should communicate this to patients. IMPACT: There is a disparity in patients' perceptions, understanding and preferences for the term 'malnutrition' and there are inconsistencies in how health workers communicate malnutrition to patients. To support patients' recognition and understanding of their nutritional status, it is imperative for health workers to consider how they discuss malnutrition with patients.

Incidence and outcomes of in-hospital nutritional decline: A prospective observational cohort study in adult patients.

BACKGROUND AND AIMS: Hospital malnutrition is associated with higher healthcare costs and worse outcomes. Only a few prospective studies have evaluated trends in nutritional status during an acute stay, but these studies were limited by the short timeframe between nutrition assessments. The aim of this study was to investigate changes in nutritional status, incidence of hospital-acquired malnutrition (HAM), and the associated risk factors and outcomes in acute adult patients admitted for >14 days. METHODS: A prospective observational cohort study was conducted in two medical and two surgical wards in a tertiary hospital in Brisbane, Australia. Nutrition assessments were performed using the Subjective Global Assessment at baseline (day eight) and weekly until discharge. Nutritional decline was defined as a change from well-nourished to moderate/severe malnutrition (HAM) or from moderate to severe malnutrition (further decline) >14 days after admission. RESULTS: One hundred and thirty patients were included in this study (58.5% male; median age 67.0 years (IQR 24.4), median length of stay 23.5 days (IQR 14)). At baseline, 70.8% (92/130) of patients were well-nourished. Nutritional decline occurred in 23.8% (31/130), with 28.3% (26/92) experiencing HAM. Of the patients with moderate malnutrition on admission (n = 30), 16% (5/30) continued to decline to severe malnutrition. Improvement in nutritional status from moderate and severe malnutrition to well-nourished was 18.4% (7/38). Not being prescribed the correct nutrition care plan within the first week of admission was an independent predictor of in-hospital nutritional decline or remaining malnourished (OR 2.3 (95% CI 1.0-5.1), p = 0.039). In-hospital nutritional decline was significantly associated with other hospital-acquired complications (OR 3.07 (95% CI 1.1-8.9), p = 0.04) and longer length of stay (HR 0.63 (95% CI 0.4-0.9), p = 0.044). CONCLUSION: This study found a high rate of nutritional decline in acute patients, highlighting the importance of repeated nutrition screening and assessments during hospital admission and proactive interdisciplinary nutrition care to treat or prevent further nutritional decline.

The association of prealbumin, transferrin, and albumin with immunosenescence among elderly males.

OBJECTIVE: As people get older, the innate and acquired immunity of the elderly are affected, resulting in immunosenescence. Prealbumin (PAB), transferrin (TRF), and albumin (ALB) are commonly used markers to monitor protein energy malnutrition (PEM). However, their relationship with the immune system has not been fully explored. METHODS: In our study, a total of 93 subjects (≥65 years) were recruited from Tongji Hospital between January 2015 and February 2017. According to the serum levels of these proteins (PAB, TRF, and ALB), we divided the patients into the high serum protein group and the low serum protein group. Then, we compared the percent expression of lymphocyte subsets between two groups. RESULTS: All the low serum protein groups (PAB, TRF, and ALB) had significant decreases in the percentage of CD4+ cells, CD3+CD28+ cells, CD4+CD28+ cells and significant increases in the percentage of CD8+ cells, CD8+CD28- cells. PAB, TRF, and ALB levels revealed positive correlations with CD4/CD8 ratio, proportions of CD4+ cells, CD3+CD28+ cells, CD4+CD28+ cells, and negative correlation with proportions of CD8+ cells, CD8+CD28- cells. CONCLUSIONS: This study suggested PAB, TRF, and ALB could be used as immunosenescence indicators. PEM might accelerate the process of immunosenescence in elderly males.

A Case of Multi-Organ Failure Secondary to Malabsorption Occurring in the Presence of Acute-on-Chronic Pancreatitis.

This case report highlights a concerning and complex case of a middle-aged female presenting with severe malabsorption, diarrhea, and subsequent malnutrition. The patient's weight dramatically dropped from 85 lbs to 50 lbs over the course of two to four months. The medical history included ongoing pancreatitis, esophageal ulcers, and previous surgeries for a dermoid cyst in the brain and cervical neoplasia. Upon admission to the hospital, the patient received total parenteral nutrition (TPN) on the first day, but this led to delirium due to refeeding syndrome. Refeeding syndrome is a well-known condition that can occur when malnourished individuals receive too much nutrition too quickly, causing metabolic imbalances and potentially serious complications. Subsequently, during the second hospitalization, the patient did not receive TPN but was instead administered 5% dextrose with 20 mEq of potassium chloride (KCl). Unfortunately, her condition worsened, leading to multiorgan failure. During the third hospitalization, TPN was reintroduced under consultation and hospitalist evaluation, and the patient's symptoms improved. Overall, this case report outlines a complex case with multiple medical issues, including severe malnutrition, which required careful management and consideration of the patient's unique needs. It underscores the importance of cautious nutritional support for severely malnourished individuals to avoid complications such as refeeding syndrome. The case also emphasizes the value of interdisciplinary collaboration and continuous monitoring to achieve successful outcomes in such complex situations.

Blood Selenium Concentrations Are Inversely Associated with the Risk of Undernutrition in Older Adults.

BACKGROUND: Selenium is an essential trace element with an antioxidant and anti-inflammatory capacity that has been associated in experimental studies with beneficial effects on appetite control, the regulation of the gut microbiota, and control of the anabolic-catabolic balance. The main aim of the present study was to evaluate the association between circulating selenium concentrations and the risk of developing undernutrition in older adults. METHODS: This was a cohort study with 1398 well-nourished community-dwelling individuals aged ≥ 65 years residing in Spain in 2017, who were followed for a mean of 2.3 years. Whole blood selenium was measured at baseline using inductively coupled plasma-mass spectrometry. Undernutrition was assessed at baseline and at follow-up, and defined as having at least one of the three GLIM phenotypic criteria (involuntary weight loss, a low body mass index, and a reduced muscle mass) and at least one of the two etiologic criteria (reduced food consumption or nutrient assimilation and inflammation/disease burden). RESULTS: During the follow-up, 142 participants (11%) developed moderate undernutrition and 113 (8.8%) severe undernutrition. The standardized relative risks of moderate and severe undernutrition at the 75th percentile of Se levels versus the 25th were 0.90 and 0.70, respectively. In dose-response analyses, the risk of severe undernutrition decreased linearly with increasing selenium concentrations. This association was independent of protein intake or diet quality and was stronger among participants with a diagnosis of a musculoskeletal disorder. CONCLUSIONS: The results suggest that an adequate dietary selenium status is needed to prevent undernutrition in older adults. Also, this may open the door for clinical trials with selenium supplementation, at doses considered as safe, to prevent undernutrition.

Health inequalities of global protein-energy malnutrition from 1990 to 2019 and forecast prevalence for 2044: data from the Global Burden of Disease Study 2019.

OBJECTIVES: Protein-energy malnutrition poses a serious medical problem worldwide. This study aims to describe the global burden, trends, and health inequalities of protein-energy malnutrition and forecasts for future prevalence. STUDY DESIGN: This was a comprehensive analysis based on data provided by the Global Burden of Disease Study 2019. METHODS: Data were obtained from the Global Health Data Exchange query tool, including prevalence, deaths, disability-adjusted life years (DALYs) and sociodemographic index (SDI). The estimated annual percentage changes were calculated to evaluate temporal trends. We quantified cross-country inequalities in protein-energy malnutrition burden and predicted the prevalence number and rate to 2044. RESULTS: Globally, there were 147,672,757 (130,405,923 to 167,471,359) cases of protein-energy malnutrition in 2019, with 212,242 (185,403 to 246,217) deaths. Eastern Sub-Saharan Africa had the highest age-standardised death and DALY rates in 2019. From 1990 to 2019, the global age-standardised prevalence rate of protein-energy malnutrition showed an upward trend, while the age-standardised death rate showed a downward trend. A significant decline occurred in SDI-related health inequality, from 2126.1 DALYs per 100,000 persons between the poorest and richest countries in 1990 to 357.9 DALYs per 100,000 persons in 2019. There was a trend of decreasing age-standardised death and DALY rates along with increases in the SDI. Frontier analyses showed that there is much room for improving the current situation of protein-energy malnutrition in some countries. In the next 35 years, the prevalence of protein-energy malnutrition will continue to increase. CONCLUSION: Although the disease burden of protein-energy malnutrition has greatly decreased since 1990 and health inequalities between countries are shrinking, the prevalence in Asian and African countries may continue to increase. Focussing on regional differences and strengthening the nutritional intake of people in underdeveloped areas are necessary to reduce future burdens.

Opportunities for Patient Participation in Perioperative Malnutrition Care: A Qualitative Study.

Introduction: In the perioperative period of hospitalization, barriers to food intake are common due to special nutritional needs, compromised nutritional status, and metabolic stress. Good nutritional care call for an interdisciplinary approach. And patients themselves may also play an essential role in managing nutritional care. Objective: This study aimed to explore how patients with malnutrition experience nutritional care, their perspectives on patient participation, and their own role in malnutrition care in the perioperative period of hospitalization. Methods: A qualitative study was conducted using an interpretive phenomenological approach. To follow patients' experiences, in-depth longitudinal interviews were undertaken before, during, and after hospitalization. Interview transcripts were analyzed thematically using open, axial, and selective coding and interpreted in an iterative process. Results: Fifty-six interviews were undertaken with 26 patients with malnutrition scheduled for surgery and during the perioperative period of hospitalization. Four themes were identified: (1) unawareness and stigmata about being malnourished, (2) feasibility of optimal nutritional care, (3) needs and expectations for self-management, and (4) barriers and facilitators of taking own responsibilities in nutritional care. Conclusion: Awareness and responsiveness to patients' perspectives, motivation, and compliance are prerequisites for patient participation in malnutrition care. This requires good communication between healthcare professionals and patients in all phases of hospitalization.

Protein-Energy Malnutrition Is Associated with Worse Outcomes in Patients with Atrial Fibrillation: A Nationwide Analysis.

Protein-energy malnutrition (PEM), which leads to a reduced ability of tissues to regenerate and repair themselves, may exacerbate many chronic diseases, including atrial fibrillation (AF), which occurs as a response of the heart to chronic inflammation. However, population-based studies examining the association between PEM and the prevalence and health care burden of AF are lacking. The aim of this retrospective cohort study was to estimate the impact of PEM on the prevalence and clinical outcomes of hospitalization for AF. The National Inpatient Sample (NIS) 2016 and 2017 datasets were searched for data on hospitalized adult patients with AF as a principal diagnosis; we subsequently identified AF patients with and without PEM as a secondary diagnosis using International Classification of Diseases, Tenth Revision (ICD-10), codes. The primary outcome of our study was inpatient mortality, while the secondary outcomes were hospital length of stay (LOS), total hospital cost (THC), cardiogenic shock, pacemaker insertion, successful ablation, and restoration of cardiac rhythm. Propensity score-weighted analysis was used accordingly to adjust for confounders. Out of 821,630 AF hospitalizations, 21,385 (3%) had PEM. Hospitalization for AF with PEM led to a statistically significant increase in mortality (adjusted odds ratio [aOR], 2.30; 95% confidence interval [CI], 1.93-2.75; P < .001) with an adjusted increase in the THC of $15,113 (95% CI, 11,246-18,980; P < .001), a 2-day increase in the LOS (95% CI, 1.92-2.41; P < .001), increased odds of cardiogenic shock (aOR, 1.36; 95% CI, 1.01-1.85; P = .04), and decreased odds of undergoing successful ablation (aOR, .71; 95% CI,.56-.88; P = .002) and achieving the restoration of cardiac rhythm (aOR, 0.56; 95% CI, 0.49-0.0.63; P ≤ .001) compared to those without PEM. These results indicate that PEM is associated with worse in-hospital outcomes in patients with AF. This potential association suggests that nutritional rehabilitation may be essential for improving hospitalization outcomes in AF patients.

Undernutrition is still highly frequent in hospitalized children with cystic fibrosis.

The aim of our study was to assess the nutritional status of hospitalized children with cystic fibrosis. We extracted data from the ePINUT surveys. Undernutrition was defined as a body mass index (BMI) of <18.5 according to the International Obesity Task Force cut-off, and the nutritional status goal was defined as a BMI z-score ≥0 SD for children older than 2 years and a weight-for-height z-score ≥0 SD for those younger than 2 years. Undernutrition frequency in the 114 patients with cystic fibrosis was 46% and was higher than in children with other chronic diseases (n = 5863; 30.5%; p = 0.001); 81% of children were below the nutritional status goal. Undernutrition frequency in cystic fibrosis is higher than in other chronic diseases.

Qualitative Research as a Basis for Transforming an Annual Plague Into an Economic and Nutrition Opportunity for Youths and Their Families in Madagascar: "From Harmful to Useful Critters" for Sustainable Development.

BACKGROUND: Madagascar is among the 10 highest burden countries for malnutrition. Protein-energy malnutrition, anemia, and vitamin deficiencies are major public health problems. Hunger is exacerbated by an annual locust invasion. The current policy of large-scale government spraying of pesticides from planes is logistically complex, costly, and damaging to the environment. OBJECTIVE: Our research aimed to study the feasibility of turning the locust invasion into a protein-rich food supply for families and an economic opportunity for youth. METHODS: We conducted 20 focus group discussions (FGDs) with females and males aged 18-24 and 25 years or older and with female artisans in 6 swarm communes in Madagascar's south to understand enablers and barriers to collection, preparation, and consumption of locusts. RESULTS: Enablers include consumption by all ages in Antandroy culture and perception of locusts as a delicacy, tasty, and free. Family members have different roles in the collection and preparation of locusts. Local technologies for mass collection include digging trenches in fields and entrapment via sisal netting. Common preparations include boiling in salted water, drying, skewering, frying, and grinding locusts into flour. Disablers include pesticide contamination of locusts and the view that locusts are a famine food. CONCLUSION: Our research provided a first step in demonstrating the feasibility of transforming locust infestations into economic and nutritional opportunities in a fragile environment with high levels of poverty and malnutrition. It contributes to advocacy in Madagascar to end the use of pesticides. It responds to the government desire to address the protein-energy malnutrition burden and youth poverty in an integrated way.

Correlation of Serum Asprosin Levels With Normalized Protein Catabolic Rate in Patients Receiving Peritoneal Dialysis Treatment.

Background Peritoneal dialysis patients are malnourished due to loss of protein in the dialysate and inadequate dialysis, although they take additional calories every day during treatment. Many parameters are used to assess nutritional status, with normalized protein catabolic rate (nPCR) being one of the most common. Asprosin, a novel adipokine secreted by adipose tissue, peaks during fasting and induces hepatic glucose release through the activation of the G-protein-cAMP-PKA pathway, which has been indicated to have a curative effect on chronic inflammation. In this study, we aimed to investigate the relationship between asprosin levels and nutritional parameters in patients receiving peritoneal dialysis treatment as well as to investigate the applicability of more practical tests. Methodology A total of 70 peritoneal dialysis patients, 35 female (59%) and 24 male (41%), were included in the study. The mean age of the patients was 53 ± 14 years (range = 18-80 years), and the median peritoneal dialysis duration was 31.5 months (range = 20-56.2 months). The most common etiologic cause was hypertension (37%). Patients over 18 years of age who had been receiving peritoneal dialysis treatment for at least 24 months were included in the study. The correlation between patients' nPCR levels and serum asprosin, body mass index, and lipids was evaluated. Results The correlation between the level of nPCR and the serum asprosin level, body mass index, and lipids was evaluated. Patients with nPCR <0.815 were considered malnourished, and factors affecting malnutrition were determined by univariate analysis. Among the factors affecting malnutrition according to univariate analysis, those with p-value <0.05 were analyzed by multivariate analysis. Low asprosin level was one of the independent factors affecting malnutrition in patients (Exp(B) = 0.944, 95% confidence interval (CI) = 0.896-0.994). Other independent factors affecting malnutrition were Kt/V (Exp(B) = 0.018, 95% CI = 0.001-0.550) and residual renal function (Exp(B) = -0.004, 95% CI = 0.993-0.999). Conclusions There is a need for more accessible tests and reliable parameters to evaluate dialysis and nutritional deficiency in peritoneal dialysis patients. One possible hormone that could serve as a guide is asprosin.

Impact of protein-energy malnutrition on outcomes of patients with diffuse large B cell lymphoma admitted for inpatient chemotherapy.

Background: Protein-energy malnutrition (PEM) is a major factor contributing to morbidity and mortality in cancer patients. Empiric data are limited on the effect of PEM on the outcomes of patients receiving chemotherapy in diffuse large B cell lymphoma (DLBCL). Methods: A retrospective cohort study was designed using data from the National Inpatient Sample for 2016 to 2019. Adult patients admitted for chemotherapy with DLBCL were stratified based on the presence of PEM. Primary outcomes assessed were mortality, length of stay, and total hospital charges. Results: PEM was associated with an increased odds of mortality, 2.21% vs 0.25% (adjusted odds ratio 8.20, P < 0.001, 95% confidence interval [CI] 4.92-13.69). There was also an increased length of stay in patients with PEM, 7.89 vs 4.85 days (adjusted difference of 3.01 days, P < 0.001, 95% CI 2.37-3.66), as well as an increase in total charges, $137,940 vs $69,744 (adjusted difference of $65,427, P < 0.001, 95% CI $38,075-$92,778). Similarly, the presence of PEM was associated with increased odds of several secondary outcomes measured, including neutropenia, Candida sepsis, septic shock, acute respiratory failure, and acute kidney injury compared to the other cohort. Conclusion: This study demonstrated an eightfold increased odds of mortality and concomitant prolonged length of stay with a 50% total charge increment in malnourished individuals with DLBCL compared to those without PEM. Prospective trials to evaluate PEM as an independent prognostic marker of chemotherapy tolerance and adequate nutritional support can improve clinical outcomes.

Assessment of Serum Vitamin D Status and Its Associated Health Problem Among Children With Protein Energy Malnutrition: A Cross-Sectional Research Study in Central Rural India.

Background Protein energy malnutrition (PEM) is a condition that results from inadequate intake of both macronutrients and micronutrients, leading to a lack of energy. The condition can manifest quickly or gradually, ranging from mild to severe. It predominantly affects children in low-income countries who do not receive enough calories and proteins. In developed nations, it is more prevalent among older individuals. PEM is more common in children as they consume less protein. In rare cases in developed countries, it may result from fad diets or a lack of knowledge about children's nutritional requirements, especially in cases of milk allergy. Vitamin D plays a critical role in bone growth and development by facilitating the absorption of calcium and phosphorus from food and supplements. Additionally, vitamin D has been linked to a reduced risk of infections, immune system disorders, diabetes, high blood pressure, and heart disease. Aims and objectives The primary objective of this study is to evaluate serum vitamin D levels and their relationship with health complications in children affected by PEM. The specific aim is to estimate the serum vitamin D levels in children with PEM who exhibit symptoms of being underweight, stunting (limited linear growth), wasting (abrupt weight loss), or edematous malnutrition (kwashiorkor). Additionally, this study seeks to analyze the correlation between serum vitamin D levels and the associated health problems in children with PEM. Materials and methods This cross-sectional study employed an analytical research approach. A total of 45 children with PEM participated in the study. Data were collected through a venipuncture method, and serum vitamin D level was assessed using an enhanced chemiluminescence method. The children's pain was assessed using a visual analogue scale, and developmental delay was evaluated using an assessment chart. Data were analyzed using SPSS Version 22 (IBM Corp., Armonk, NY). Results The study's results indicate that a considerable proportion of children, specifically 46.6%, were deficient in vitamin D, whereas 42.2% exhibited insufficiency and only 11.2% had sufficient levels of the vitamin. Pain assessment using the visual analogue scale classification revealed that 15.6% of children reported no pain, 60% reported mild pain, and 24.4% reported moderate pain. The mean and standard deviation of vitamin D levels correlated with developmental delay were 4.22±0.212 and 5.34±0.438, respectively. Similarly, the mean and standard deviation of vitamin D levels correlated with pain were 4.22±0.212 and 2.98±0.489, respectively. The Pearson correlation coefficient for vitamin D levels and pain was 0.010, with a significant level of 0.989, significantly lower than the tabulated value at a 5% significance level. Conclusion Based on the study's findings, it was concluded that children who suffer from PEM are at a risk of developing vitamin D deficiency, which can result in adverse health outcomes, including developmental delay and pain.

Nutritional Support for Alcoholic Liver Disease.

Malnutrition is a common finding in alcohol use disorders and is associated with the prognosis of patients with alcoholic liver disease (ALD). These patients also frequently show deficiencies in vitamins and trace elements, increasing the likelihood of anemia and altered cognitive status. The etiology of malnutrition in ALD patients is multifactorial and complex and includes inadequate dietary intake, abnormal absorption and digestion, increased skeletal and visceral protein catabolism, and abnormal interactions between ethanol and lipid metabolism. Most nutritional measures derive from general chronic liver disease recommendations. Recently, many patients with ALD have been diagnosed with metabolic syndrome, which requires individualized treatment via nutritional therapy to avoid overnutrition. As ALD progresses to cirrhosis, it is frequently complicated by protein-energy malnutrition and sarcopenia. Nutritional therapy is also important in the management of ascites and hepatic encephalopathy as liver failure progresses. The purpose of the review is to summarize important nutritional therapies for the treatment of ALD.

Protein-energy malnutrition and worse outcomes after major cancer surgery: A nationwide analysis.

Background: Protein-energy malnutrition (PEM) has been recognized as a poor prognostic factor in many clinical issues. However, nationwide population studies concerning the impact of PEM on outcomes after major cancer surgery (MCS) are lacking. We aimed to evaluate the postoperative outcomes associated with PEM following MCS. Methods: By using the Nationwide Inpatient Sample database, data of patients undergoing MCS including colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, lung resection, pancreatectomy, or prostatectomy were analyzed retrospectively from 2009 to 2015, resulting in a weighted estimate of 1,335,681 patients. The prevalence trend of PEM, as well as mortality and major complications after MCS were calculated. Multivariable regression analysis was applied to estimate the impact of PEM on postoperative outcomes after MCS. Results: PEM showed an estimated annual percentage increase of 7.17% (95% confidence interval (CI): 4-10.44%) from 2009 to 2015, which contrasts with a 4.52% (95% CI: -6.58-2.41%) and 1.21% (95% CI: -1.85-0.56%) annual decrease in mortality and major complications in patients with PEM after MCS. PEM was associated with increased risk of mortality (odds ratio (OR)=2.26; 95% CI: 2.08-2.44; P < 0.0001), major complications (OR=2.46; 95% CI: 2.36-2.56; P < 0.0001), higher total cost ($35814 [$22292, $59579] vs. $16825 [$11393, $24164], P < 0.0001), and longer length of stay (14 [9-21] days vs. 4 [2-7] days, P < 0.0001), especially in patients underwent prostatectomy, hysterectomy and lung resection. Conclusions: PEM was associated with increased worse outcomes after major cancer surgery. Early identification and timely medical treatment of PEM for patients with cancer are crucial for improving postoperative outcomes.

Intradialytic parenteral nutrition for patients on hemodialysis: when, how and to whom?

Hemodialysis is associated with high morbidity and mortality rates as well as low quality of life. Altered nutritional status and protein-energy wasting are important indicators of these risks. Maintaining optimal nutritional status in patients with hemodialysis is a critical but sometimes overlooked aspect of care. Nutritional support strategies usually begin with dietary counseling and oral nutritional supplements. Patients may not comply with this advice or oral nutritional supplements, however , or compliance may be affected by other complications of progressive chronic kidney disease. Intradialytic parenteral nutrition (IDPN) may be a possibility in these cases, but lack of knowledge on practical aspects of IDPN delivery are seldom discussed and may represent a barrier. In this review, we, as a consensus panel of clinicians experienced with IDPN, survey existing literature and summarize our views on when to use IDPN, which patients may be best suited for IDPN, and how to effectively deliver and monitor this strategy for nutritional support.

Genome Editing and Protein Energy Malnutrition.

Protein-energy malnutrition is a state of disordered catabolism resulting from metabolic derangements or starvation. It is associated with chronic disease, hypoglycemia, hypothermia, serious infections, and even an increased prevalence of morbidity and mortality in countries with poor socioeconomic or environmental factors. Adequate food administration is essential to satisfy the main caloric and nutritional demands of humans. The most significant factors seen in the development of protein-energy malnutrition in areas of high incidence, such as underdeveloped countries, are inadequate food and nutrient supplies. It has been well established that one of the strategies to alleviate undernourishment is the biofortification of staple crops. This is because vegetables and plants are significant sources of crucial nutrients for human growth and development. To enhance plant nutrition, recent tactics aim to formulated balanced and diverse diets with acceptable levels of vitamins and minerals that benefit human health. New advances in plant biotechnology and animal productivity could control key enzymes in several metabolic pathways, enriching important nutrients such as iron and vitamins and decreasing the content of disadvantageous compounds such as acrylamide-forming amino acids and phytic acids. Numerous biofortified crops such as rice, maize, and wheat have been created to resolve the problem of nutrition deficiencies. Some examples of these methodologies are genome editing engineered nucleases, transcriptional activator-like effector nucleases, zinc finger nucleases, and clustered regularly interspaced short palindromic repeats and associated Cas9 endonuclease which have been created and widely studied for their application, efficiency, and specificity.

Early childhood malnutrition impairs adult resting brain function using near-infrared spectroscopy.

Introduction: Early childhood malnutrition affects 200+ million children under 5 years of age worldwide and is associated with persistent cognitive, behavioral and psychiatric impairments in adulthood. However, very few studies have investigated the long-term effects of childhood protein-energy malnutrition (PEM) on brain function using a functional hemodynamic brain imaging technique. Objective and methods: This study aims to investigate functional brain network alterations using near infrared spectroscopy (NIRS) in adults, aged 45-51 years, from the Barbados Nutrition Study (BNS) who suffered from a single episode of malnutrition restricted to their first year of life (n = 26) and controls (n = 29). A total of 55 individuals from the BNS cohort underwent NIRS recording at rest. Results and discussion: Using functional connectivity and permutation analysis, we found patterns of increased Pearson's correlation with a specific vulnerability of the frontal cortex in the PEM group (ps < 0.05). Using a graph theoretical approach, mixed ANCOVAs showed increased segregation (ps = 0.0303 and 0.0441) and decreased integration (p = 0.0498) in previously malnourished participants compared to healthy controls. These results can be interpreted as a compensatory mechanism to preserve cognitive functions, that could also be related to premature or pathological brain aging. To our knowledge, this study is the first NIRS neuroimaging study revealing brain function alterations in middle adulthood following early childhood malnutrition limited to the first year of life.

Effects of perinatal protein restriction on the oxidative balance in the hypothalamus of 60-day-old rats / Efeitos da restrição proteica perinatal sobre o balanço oxidativo no hipotálamo de ratos de 60 dias de idade

ABSTRACT Objective Evaluate the effects of maternal low-protein diet on the oxidative stress in the hypothalamus of 60-day-old rats. Methods Male Wistar rats were divided into two experimental groups according to the mother's diet during pregnancy and lactation; control group (NP:17% casein n=6) and a malnourished group (LP:8% casein n=6). At 60 days of life, the rats were sacrificed for the collection of the hypothalamus for further biochemical analysis. Results Our results showed an increase in oxidative stress in malnourished group, observed through an increase in carbonyl content (p=0.0357), a reduction in the activity of the glutathione-S-transferase enzyme (p=0.0257), and a reduction in the non-enzymatic antioxidant capacity evidenced by the decrease in the ratio reduced glutathione/oxidized glutathione (p=0.0406) and total thiol levels (p=0.0166). Conclusion A low-protein diet during pregnancy and lactation is closely associated with increased oxidative stress and reduced antioxidant capacity in the hypothalamus of sixty-day-old rats.

RESUMO Objetivo Avaliar os efeitos da restrição proteica materna sobre o estresse oxidativo no hipotálamo de ratos de 60 dias de idade. Métodos Ratos Wistar machos foram divididos em dois grupos experimentais de acordo com a dieta da mãe durante a gestação e lactação: grupo controle (NP: 17% caseína n=6) e grupo desnutrido (LP: 8% caseína n=6). Aos 60 dias de vida, os ratos foram sacrificados para coleta do hipotálamo para posterior análise bioquímica. Resultados Os resultados demonstraram aumento do estresse oxidativo no grupo desnutrido, observado através do aumento do conteúdo de cabonilas (p=0,0357) e redução da atividade da enzima glutationa-S-transferase (p=0,0257) e da capacidade antioxidante não enzimática, evidenciada pela queda da razão glutationa reduzida/glutationa oxidada (p=0,0406) e dos níveis de tióis totais (p=0,0166). Conclusão Uma dieta com baixo teor de proteínas durante a gestação e lactação está intimamente associada ao aumento do estresse oxidativo e à redução da capacidade antioxidante no hipotálamo de ratos de 60 dias de vida.

Ocular Morbidity Among Children With Protein Energy Malnutrition in Northwest Nigeria.

Background: Protein energy malnutrition (PEM) remains a major health challenge in Nigeria, especially Northern Nigeria. Its association with ocular morbidity and irreversible blindness has been previously documented. There are however limited recent literature on these ocular manifestations, which may have evolved over the years. This study is thus relevant to establish a current baseline for the ocular manifestations associated with PEM in Northern Nigeria. Materials and Methods: This was a comparative, cross-sectional study. The sample size was 400 children; 200 with PEM, and 200 without PEM. Consenting parents with children between 6 - 59 months of age diagnosed with PEM, and those without PEM were recruited. Sociodemographic characteristics, general and ocular history were documented. A detailed ocular examination which included visual acuity assessment, examination of ocular adnexae, as well as the anterior and posterior segment of the eyes were done. Data was collected in a structured proforma, and analysed with the SPSS version 21, and Windows WinPepi softwares. Results: Abnormal ocular findings were significantly higher in the PEM group compared to the non-malnourished group [46.5% vs 24%, OR = 2.910 (1.891, 4.477), p = < 0.001]. The predominant ocular examination findings in the PEM and non-malnourished groups were infective conjunctivitis (35.5% vs 17%), lid oedema (11% vs 0%), signs of xerophthalmia (6% vs 0%) and visual impairment (3% vs 0%). Conclusion: PEM is still complicated by varying severity of ocular morbidity, with the potential of progression to irreversible blindness.
